Background: Mastoiditis frequently occurs in children as they are more susceptible to middle ear infections, but infrequently occurs in adults. A rare complication that results from mastoiditis and an obstructing cholesteatoma is a Bezold's abscess, of which there are less than 100 reported cases in literature to date., Case Presentation: Here, we present a case of a 72-year-old Caucasian man who has had no history of prior ear infections and was found to have a cholesteatoma and advanced acute coalescent mastoiditis complicated by a Bezold's abscess., Conclusions: Bezold's abscess is a rare entity infrequently encountered in the modern era, likely owing to more prompt treatment of otitis media. Cholesteatoma poses a great risk for both the development of otitis media and further progression to mastoiditis and its associated complications, such as Bezold's abscess. Knowledge of said abscess is crucial; without prompt recognition, further spread of infection can occur with vascular or mediastinal involvement., (© 2024. The Author(s).)

Objective: To analyze the clinical characteristics of middle ear mastoiditis combined with sigmoid sinus thrombophlebitis in children. Methods: Author retrospectively analyzed the clinical data of 6 children with middle ear mastoiditis combined with sigmoid sinus thrombophlebitis who were hospitalized in the Department of Infectious Diseases and Department of Neurology with first diagnosis of fever/headache, and subsequently underwent middle ear mastoidectomy in our department. All patients underwent comprehensive otoscopic, audiologic, imaging, and pathogenetic examinations. Clinical manifestations, pathogenetic features, treatment methods and prognosis were summarized, and the follow-up period was 3-6 months. Results: All 6 cases were first diagnosed with intracranial complications such as fever and headache in the internal medicine department. Within one month, all patients developed ear symptoms including pain, discharge, and hearing loss. Audiologic examination revealed conductive hearing loss in five cases and total deafness in one case. MRI, MRV and MRA examinations suggested that there were 6 cases of middle ear infection combined with thrombophlebitis of the ethmoid sinus, of which 3 cases had thrombus in the ethmoid sinus. 6 cases received surgical treatments: 2 cases of radical mastoidectomy+grommet Insertion, and 4 cases of radical mastoidectomy. Pathogenetic examination identified Streptococcus pneumoniae in three cases, Pseudomonas aeruginosa in one case, Enterobacter cloacae complex in one case, and no pathogens were detected in one case. Postoperative pathology was inflammatory granulation in all 6 cases. Follow-up was 3-6 months with no recurrence of intracranial and middle ear lesions on regular review. Conclusion: Children with recurrent fever, headache, and a recent history of acute and chronic otitis media should be evaluated for the possibility of sigmoid sinus thrombophlebitis, and imaging tests should be performed in a timely manner to clarify the diagnosis. Once diagnosed, surgery to remove the lesions around the ethmoid sinus, smooth drainage combined with antibiotic therapy is the most direct and effective treatment, and anticoagulation therapy is given when necessary. Timely diagnosis, multidisciplinary collaboration, and accurate timing of the management of primary foci and comorbidities are crucial to the treatment of the disease., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Introduction: Acute mastoiditis (AM) can rapidly become life-threatening with various intracranial complications. The standard care includes antibiotics, mastoidectomy, and drainage. Reports show varying preferences for conservative and surgical treatments, with a more conservative approach gaining popularity. In this study we aim to evaluate the presenting symptoms, management and outcomes of patients presenting with intracranial complications secondary to acute mastoiditis., Methods: Retrospective review for all children admitted for acute mastoiditis for 12 years period (January 2010-December 2021). Children who had mastoiditis associated with intracranial complications were included in the study. STROBE guidelines were followed in this study., Results: 23 patients were diagnosed with acute mastoiditis with intracranial complications. The mean age was 2.1 years. The most common presenting sign was fever, followed by otalgia. The most common pathogens were Fusobacterium necrophorum and Streptococcus pneumoniae. The most common intracranial complication was sinus vein thrombosis (SVT) affecting 13 patients. Eventually, 10 patients underwent cortical mastoidectomy during 1-6 days upon admission, with an average of 3.2 days. During the follow-up period patients were monitored for clinical progression. Patients who did not show clinical improvement such as persistent fever, worsening symptoms, or the presence of neurological symptoms were treated surgically. The length of stay was an average of 15.5 days overall, with no significantly longer hospital stay in patients who were treated surgically compared to patients who were treated conservatively (17.1 days vs. 14.2 days, P = .26)., Conclusion: Intracranial complications of acute mastoiditis remain a significant challenge. Selected patients with intracranial complications can be treated conservatively with close monitoring, without increasing the risk of immediate or long-term complications. Initial antimicrobial treatment should cover anaerobic bacteria, as it correlates with severe complications., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background and Purpose: Fusobacterium necrophorum ( F necrophorum ) is an anaerobic bacteria that causes invasive head and neck infections in children. Several studies have demonstrated an increasing prevalence of F necrophorum as the causative agent in acute mastoiditis in children, with associated high rates of intracranial complications such as epidural abscess and sinus venous thrombosis, to name a few. F necrophorum requires a treatment protocol that differs from the empiric treatment that is tailored to more common pathogens (eg, group A streptococci, Streptococcus pneumonia), and hence expediting the diagnosis is important. For evaluating complicated acute mastoiditis in children, cranial CT venography remains the imaging study of choice in most medical centers due to its availability in emergency situations. Based on our clinical experience, our hypothesis is that children with F necrophorum -associated complicated acute mastoiditis can be differentiated from those with other etiologies using CT venography., Materials and Methods: CT venography studies of 76 children hospitalized and treated for complicated acute mastoiditis were retrospectively reviewed. Retrieved imaging data included intracranial complications (epidural abscess, sinus venous thrombosis), cranial bone-related complications, and extracranial complications (subperiosteal abscess, temporomandibular joint abscess, and soft-tissue inflammation). The cohort was divided into children with F necrophorum -related disease (study group) and those with non- F necrophorum -related disease (control group)., Results: Thirty-seven children (49%) comprised the study group, and 39 children in whom the causative agents were other bacteria comprised the control group. There were significantly higher rates of complications in the study group: sinus venous thrombosis ( P < .001), perisigmoid epidural abscess ( P  = .036), and extramastoid osteomyelitis ( P  < .001). Thrombosis in venous sites beyond the sigmoid sinus and jugular foramen (a pattern consistent with an otogenic variant of Lemierre syndrome) and emphysematous osteomyelitis were found only among children in the F necrophorum -related study group (32% and 22% accordingly)., Conclusions: In children with complicated acute mastoiditis, CT venography findings of emphysematous osteomyelitis and/or thrombosis in venous sites beyond the sigmoid sinus and jugular foramen (a pattern consistent with the otogenic variant of Lemierre syndrome) should lead the radiologist to suggest F necrophorum -related mastoiditis., (© 2024 by American Journal of Neuroradiology.)

Background: Acute mastoiditis (AM) is a potentially life-threatening condition primarily affecting children. To date, there are no consistent criteria or valid guidelines for the diagnosis and treatment of pediatric AM. Therefore, this study evaluates the clinical course of AM in terms of clinical signs and treatment. In addition, a novel classification scheme for the disease and a treatment algorithm is being proposed., Methods: Patient records over a 12-year period from a single center were reviewed to identify confirmed cases of AM in children. Data collected included clinical signs, body temperature, and infection parameters during the disease, as well as radiological imaging, antibiotics, and surgical as well as conservative treatment. In addition, a classification of the AM stages was established in accordance with the findings described and practical experience, consisting of four stages (1, mastoidal irritation; 2, mild AM; 3, advanced AM; 4, advanced AM and additional complications) with corresponding treatment recommendations. In the retrospective cohort, those AM cases that were treated alongside the classification were compared with the rest concerning clinical course and outcome., Results: A total of 109 patients (mean age, 3.8 ± 3.8 years) were included. The main symptoms at hospital admission were auricular protrusion (n = 73; 67.0%), fever (n = 56; 51.4%) with a mean temperature of 38.3 ± 1.1°C, and otalgia (n = 28; 25.7%). The mean laboratory-tested levels of leukocytes and C-reactive protein at the time of hospital admission were 15.96 ± 8.7/nl and 59.6 ± 54.0 mg/L, respectively. During winter, there was a higher prevalence of AM, with peak hospital admissions in April (n = 22). The most common pathogen was Streptococcus pyogenes (32 cases). Treatment was purely conservative in four cases, whereas the remaining cases underwent surgery (41× grommet insertion, 64× plus mastoidectomy). The outcome was generally good, but in eight patients a second surgical procedure had to be performed as they showed signs of clinical deterioration. A total of 101 patients were treated according to the proposed algorithm, and all of which had a good outcome without the need for further interventions., Conclusion: Based on clinical experience in a large cohort of pediatric AM patients, a novel diagnostic and treatment algorithm has been developed and successfully tested in a retrospective cohort for AM in children to prevent further complications and to ease its management by pediatricians and otorhinolaryngologists in the emergency setting., Competing Interests: Conflicts of interest and source of funding: The authors have no conflicts of interest or source of funding to disclose., (Copyright © 2023, Otology & Neurotology, Inc.)

Objectives: Acute mastoiditis (AM) and its associated intra and extracranial complications are rare complications of acute otitis media. However, they are associated with a high morbidity. The management of AM with complications carries significant variations in approach. We aimed to evaluate the presentation of children with AM with complications to a tertiary referral centre in the United Kingdom and describe evolution of the treatment approaches., Methods: We undertook a retrospective chart review of all children admitted with AM to the University Hospitals of Leicester between 2013 and 2022., Results: Twenty-seven children were included in this study: 7 patients had sigmoid sinus thrombosis (SST), 4 had an intracranial collection, 3 had cranial nerve palsy and 16 had a subperiosteal abscess (SPA); some patients had more than 1 complication. In this study, treatment of SPA with incision and drainage (I&D) and grommet insertion was effective, as all patients treated with grommet insertion and I&D recovered well and did not require a subsequent cortical mastoidectomy. All patients with SST received anticoagulation and intravenous (IV) antibiotics; surgical input consisted of grommet insertion alone and cortical mastoidectomy was not routinely performed in these patients., Conclusion: In our series, management of SPA with grommet insertion and drainage had good outcomes. SST management mainly consisted of IV antibiotics, anticoagulation and grommet insertion with good recovery. The evidence to guide the management of complications of mastoiditis is of poor quality and further research is needed to clarify the optimal management of these complications., (© 2023 John Wiley & Sons Ltd.)

Background: Acute mastoiditis and orbital complications of acute rhinosinusitis are among the most common complications of pediatric infections in otolaryngology., Objective: The aim of this study was to investigate the frequency of pediatric acute mastoiditis in the setting of acute otitis media as well as pediatric orbital complications in the setting of acute rhinosinusitis. Data from before the pandemic were compared to data after the end of the COVID-19 restrictions., Materials and Methods: Included were hospitalized children who presented with acute mastoiditis from acute otitis media or with orbital complications from acute rhinosinusitis during the period from April 2017 to March 2023. Compared were three periods using descriptive statistics: April 2017 to March 2020 (before the pandemic in Germany), April 2020 to March 2022 (during the contact restrictions of the pandemic), and April 2022 to March 2023 (after the contact restrictions were lifted)., Results: A total of 102 children (43 with acute mastoiditis, 42%, and 59 with orbital complications of acute sinusitis, 58%) were included. During the 2022/2023 period, more than twice as many children with acute mastoiditis and approximately three times as many children with orbital complications of acute rhinosinusitis were hospitalized compared to the average of the periods 2017/2018, 2018/2019, and 2019/2020. In the 2021/2022 period, the number of these patients was below the average of previous years., Conclusion: This year's seasonal cluster of upper respiratory tract infections is associated with a higher-than-average incidence of orbital complications and mastoiditis., (© 2023.

Objectives: To identify and review key research advances from the literature published between 2019 and 2023 on the diagnosis and microbiology of otitis media (OM) including acute otitis media (AOM), recurrent AOM (rAOM), otitis media with effusion (OME), chronic suppurative otitis media (CSOM) and AOM complications (mastoiditis)., Data Sources: PubMed database of the National Library of Medicine., Review Methods: All relevant original articles published in Medline in English between July 2019 and February 2023 were identified. Studies that were reviews, case studies, relating to OM complications (other than mastoiditis), and studies focusing on guideline adherence, and consensus statements were excluded. Members of the panel drafted the report based on these search results., Main Findings: For the diagnosis section, 2294 unique records screened, 55 were eligible for inclusion. For the microbiology section 705 unique records were screened and 137 articles were eligible for inclusion. The main themes that arose in OM diagnosis were the need to incorporate multiple modalities including video-otoscopy, tympanometry, telemedicine and artificial intelligence for accurate diagnoses in all diagnostic settings. Further to this, was the use of new, cheap, readily available tools which may improve access in rural and lowmiddle income (LMIC) settings. For OM aetiology, PCR remains the most sensitive method for detecting middle ear pathogens with microbiome analysis still largely restricted to research use. The global pandemic response reduced rates of OM in children, but post-pandemic shifts should be monitored., Implication for Practice and Future Research: Cheap, easy to use multi-technique assessments combined with artificial intelligence and/or telemedicine should be integrated into future practice to improve diagnosis and treatment pathways in OM diagnosis. Longitudinal studies investigating the in-vivo process of OM development, timings and in-depth interactions between the triad of bacteria, viruses and the host immune response are still required. Standardized methods of collection and analysis for microbiome studies to enable inter-study comparisons are required. There is a need to target underlying biofilms if going to effectively prevent rAOM and OME and possibly enhance ventilation tube retention., Competing Interests: Declaration of competing interest No conflict., (Copyright © 2023 Elsevier B.V.

Objective: To investigate the microbial patterns and clinical outcomes of pediatric patients undergoing mastoidectomy for acute coalescent mastoiditis and to identify factors associated with poor outcomes and/or prolonged treatment., Study Design: Monocentric retrospective cohort study., Setting: Tertiary referral pediatric hospital in Indiana., Methods: By cross-referencing database data from the Pediatric Health Information System (PHIS) querying for all inpatient stays (patients younger than eighteen) with a diagnostic code of mastoiditis between January 1st, 2010 and August 31, 2019, and the electronic health record (Cerner) for Riley Hospital for Children, 46 patients with mastoidectomy were included. A two-tailed T-test was used to evaluate continuous parametric data. Statistical significance was determined as P < 0.05. For continuous variables, data was analyzed using continuous logistic regression. A criteria of p > 0.1 was used for inclusion in the multivariate regression., Results: Inclusion criteria was met by 46 patients. From 2010 to 2019, S. pyogenes and S. pneumoniae were the most common bacteria, each isolated in 11 of 42 bacterial isolates (26.2%). There was no growth in 35.4% (17/48) of intra-operative wound cultures. On univariate analysis, patients with negative cultures had longer length of hospital stay (LOS) (7.7 days [6.5] vs. 4.3 [2.8]; p = 0.018) as well as higher rates of PICC (peripherally inserted central catheter) placement (53.3% vs. 19.4%; p = 0.021). There was a statistically significant difference in terms of gender (p = 0.021), with 15 males and 16 females in the positive culture cohort and 13 males and 2 females in the negative culture cohort. On multivariate analysis, which included gender, PICC placement, both intracranial and extracranial complications, duration of antibiotics, and LOS, female gender was the only significant predictor of positive culture status (p = 0.039)., Conclusion: S. pyogenes and S. pneumoniae were the predominant etiologic agents in acute coalescent mastoiditis between 2010 and 2019, and negative wound cultures were associated with worse clinical outcomes., Competing Interests: Declaration of competing interest The authors declare no conflict of interest or any commercial associations., (Copyright © 2023 Elsevier B.V.

Introduction: Intratemporal or intracranial complications of acute mastoiditis are often of significant severity, can be life-threatening, and require prompt and usually aggressive treatment. This study focused on analyzing the outcomes and complications of different surgical techniques used in intracranial and intratemporal complications of acute mastoiditis, the most common complication of acute otitis media., Methods: A retrospective study of pediatric patients with mastoiditis with intratemporal and intracranial complications was designed at the Niño Jesús University Children's Hospital in Madrid, Spain, from 2005 to 2021., Results: Of 417 patients with mastoiditis, 112 patients developed intratemporal and intracranial complications, with subperiosteal abscess being the most frequent complication. The most frequently isolated pathogens were Streptococcus pneumoniae, Streptococcus pyogenes, and Fusobacterium necrophorum. The most used surgical technique was myringotomy with placement of transtympanic drainage, in 86.6% of all cases. In patients with intracranial complications, neurosurgical procedures were necessary for 19.2%, with craniotomy with mastoidectomy being the most frequent. Most of the cases evolved favorably, and only 5.4% of the patients required surgical reintervention, being more frequent in intratemporal complications. In terms of complications, we found cases of neutropenia in 3.6%, neurological sequelae in 5.4%, and permanent hearing loss in 2.7%., Conclusions: There was a favorable evolution with a low incidence of reoperation and sequelae within our series. The surgical technique of choice correlated with the severity of the complication. If the mean size of the abscess exceeds 20 mm, incision and drainage, along with myringotomy and tube placement, should be considered as the initial treatment. Closed mastoidectomy should be reserved for deteriorating of clinical evolution or acute mastoiditis with intracranial complications. Intracranial and multiple concomitant complications were associated with a more extended hospital stay, ICU occupancy, neurosurgical intervention, and risk of neurological sequelae and neutropenia. Conversely, intratemporal complications may result in permanent hearing loss., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Objectives: The neurotologic literature commonly describes venous sinus thrombosis as a complication of mastoiditis. However, thrombosis of the internal carotid artery in the setting of mastoiditis is rarely described. We aim to document a case of carotid artery thrombosis in a patient presenting with mastoiditis., Methods: We describe this case and review relevant literature., Results: A renal transplant patient was transferred to our hospital with a left middle cerebral artery (MCA) infarct due to acute mastoiditis. Examination demonstrated middle ear effusion and radiologic workup confirmed mastoid infection adjacent to the site of arterial thrombosis. During cortical mastoidectomy and facial recess approach to the middle ear, the petrous carotid bone was found to be dehiscent with pneumatization of the petrous apex. Thrombosis was found to resolve following surgery, IV antibiotics and anticoagulation. Clinically, his focal neurological deficits improved. Proximity of the infectious process to an exposed petrous carotid artery supports the hypothesis that this patient's thrombus was a product of infectious spread and extra-luminal compression., Conclusion: To our knowledge, this is the first report of MCA infarction due to petrous ICA arterial thrombus in the setting of mastoid infection. The patient's immunocompromised state may have predisposed and contributed to the adverse outcome. We advocate for aggressive management of acute mastoiditis in the immunocompromised to prevent or manage complications (such as venous thrombophlebitis as well as ICA thrombus) as these patients don't show typical signs of infection and inflammation.

Objective: Neurosurgical outcomes are not well defined in the management of pediatric patients with cerebral venous sinus thrombosis (CVST) following acute mastoiditis. Specific notable sequelae are otogenic (otitic) hydrocephalus and CVST management. Correspondingly, the aim of this study was to integrate the currently published metadata to summarize these outcomes., Methods: Electronic searches were performed using the Ovid Embase, PubMed, Scopus, and Cochrane databases from inception to November 2022 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Cohort-level data were then abstracted for analysis for appropriate pediatric patients. Outcomes were pooled by random-effects meta-analyses of proportions where possible., Results: Twenty-three study cohorts describing 312 pediatric patients with otogenic CVST were included. At a cohort level, the median patient age was 6 years among 181 boys (58%) and 131 girls (42%). Modeling indicated papilledema at presentation in 46% of cases (95% CI 30%-62%). Regarding management, antibiotics were applied universally in all cases, mastoidectomy or other otologic surgery was performed in 91% (95% CI 82%-98%), and prophylactic anticoagulation was administered in 86% (95% CI 75%-95%). There was only 1 case (0.3%) of postprocedural intracranial hemorrhage, and there were no deaths reported among all studies. Although diagnostic lumbar puncture was performed in 14% (95% CI 3%-28%) at presentation, clinical otogenic hydrocephalus was ultimately suspected in 31% (95% CI 14%-49%), and acetazolamide was given in 65% (95% CI 35%-91%) overall. There were 10 cases (3%) that proceeded to permanent CSF diversion in the form of ventricular shunting. At a median follow-up of 8 months among all studies, the venous sinus was completely recanalized in 67% (95% CI 53%-79%)., Conclusions: Most CVSTs following acute mastoiditis will recanalize with the standard use of antibiotics, otologic surgery, and anticoagulation, with minimal symptomatic hemorrhage risk. However, an appreciable proportion of these patients will develop symptomatic otogenic hydrocephalus, and it is imperative that the appropriate surveillance and workup is performed to fully optimize patient outcomes long-term. The possible need for permanent CSF diversion should be recognized.

Purpose: To analyze the prevalence and associations of facial canal dehiscence (FCD), dural exposure, and labyrinthine fistula in chronic otitis media (COM) with and without cholesteatoma., Methods: This was a retrospective study performed in an academic medical center. Patients who received tympanoplasty with mastoidectomy for COM with and without cholesteatoma were included. The prevalence of FCD, dural exposure, and labyrinthine fistula in COM with and without cholesteatoma (mastoiditis) and their relationships were analyzed., Results: A total of 189 patients, including 107 (56.6%) females and 82 (43.4%) males, with 191 ears were included. There were 149 cases (78.0%) of cholesteatoma and 42 patients (22.0%) with mastoiditis. FCD was noted in 27.5% of patients with cholesteatoma and 9.5% of patients with mastoiditis. Dural exposure was found in 21 patients (14.1%) with cholesteatoma and 4 patients (9.5%) with mastoiditis. Eleven patients (7.4%) with cholesteatoma and 1 patient (2.4%) with mastoiditis had labyrinthine fistula. Patients with a labyrinthine fistula had nearly a fivefold greater chance (OR = 4.924, 95% CI = 1.355-17.896, p = 0.015) of having FCD than those without a fistula. There was a positive correlation between dural exposure and labyrinthine fistula (P = 0.011, Fisher's exact test)., Conclusion: FCD, dural exposure, and labyrinthine fistula are common complications in COM. These complications are more frequently observed in patients with cholesteatoma than in patients with mastoiditis. Surgeons should pay more attention to the treatment of COM., (© 2022.

Background: Acute mastoiditis is a suppurative infection of mastoid air cells and is the most common intratemporal complication of otitis media., Aim: This study aimed to evaluate the demographic and clinical characteristics and treatment outcomes of children with acute mastoiditis (AM)., Patients and Methods: We retrospectively reviewed the medical records of hospitalized pediatric patients aged between 1 month and 18 years with a diagnosis of AM between May 2015 and December 2021., Results: A total of 28 hospitalized children with AM were enrolled in this study, of whom 22 (78.6%) were males and 6 (21.4%) were females with a mean ± standard deviation age of 93.5 ± 53.2 months (range = 6 months-16.1 years). The most common clinical symptoms were postauricular erythema (n = 17, 60.7%), tenderness (n = 16, 57.1%), swelling (n = 14, 50%), fever (n = 14, 50%), and auricular protrusion (n = 7, 25%). Mastoiditis complications occurred in 10 (35.7%) children. The most common extracranial complication was subperiosteal abscess (n = 8, 28.6%). The erythrocyte sedimentation rate (ESR) and the rate of antibiotic use before hospitalization were higher in patients with complicated mastoiditis (P = 0.006 and P = 0.039, respectively). Surgery was performed in 12 (42.9%) patients. Statistically, more surgical interventions were performed in patients who developed complications (P = 0.003)., Conclusion: AM continues as an important disease of childhood. Successful results are obtained with systemic antibiotic therapy and additional surgical intervention as necessary. A careful evaluation of patients with a high ESR and those who received antibiotic therapy before hospitalization is appropriate due to the correlation between these factors and the risk of complication development., Competing Interests: None

Objective: Hypertrophic pachymeningitis (HP) is a rare disorder that causes localized or diffuse inflammatory fibrosis and thickening of the dura mater. Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV)-related HP is the most frequent form of HP. Otitis media with AAV (OMAAV) patients with HP are associated with higher rates of both ANCA-negative phenotypes and disease-related mortality. However, few studies have reported the imaging characteristics of HP due to AAV/OMAAV. Therefore, we investigated this issue in the present study., Methods: This retrospective study included patients diagnosed with HP between 2011 and 2020 at our hospital. Age, sex, causative disease, serum C-reactive protein (CRP) level, and MRI data were collected from medical records. We compared the locations of MRI enhancement depending on the causative diseases., Results: Of the 18 included patients with HP (mean age, 64.1 ± 2.6 years; range, 33-77 years), 10 (55.6%) were female, 12 (66.7%) were diagnosed with AAV/OMAAV, four (22.2%) were diagnosed as idiopathic, two (11.1%) were diagnosed with invasive Aspergillus mastoiditis. Eleven (61.1%) had cranial neuropathies. Facial nerve paralysis was common in AAV/OMAAV, while abducent nerve paralysis was common in idiopathic HP. Cranial fossa enhancement was most common presentation in patients with HP, whereas inner acoustic canal (IAC) enhancement was seen only in patients with AAV/OMAAV, while HP involving the cavernous sinus was seen only in patients with idiopathic and mastoiditis., Conclusion: HP involving the IAC may be a key factor in diagnosing AAV/OMAAV., Competing Interests: Conflicts of Interest None, (Copyright © 2022.

Purpose: The aim of this study was to present a series of 6 patients with facial nerve palsy and masked mastoiditis which constituted as revelators of localized granulomatosis with polyangiitis (GPA) and to evaluate the utility of the ACR/EULAR 2017 provisional classification criteria for GPA in such cases., Methods: Study group included 58 patients with GPA. Cases with facial nerve palsy and masked mastoiditis were thoroughly analyzed., Results: The mean age of patients was 37 years. All manifested unilateral facial nerve palsy and hearing loss, while only 2 reported aural complaints suggesting inflammatory cause of the disease. All cases were qualified for surgical intervention. Intraoperative findings were similar: granulation tissue in tympanic cavity and/or pneumatic spaces of the mastoid process. Only 50% of histopathological results suggested vasculitis. In all cases, elevated levels of antineutrophil cytoplasmic antibodies (ANCA) against peroxidase 3 (PR3-ANCA) were determined. Two patients presented rapid progression of the disease and died within 1 week and 2 months, respectively. Four other patients manifested gradual improvement of hearing and facial nerve function after treatment., Conclusion: GPA should be included into differential diagnosis in all cases of persistent facial nerve palsy especially when otological symptoms coexist. Even localized GPA could be very aggressive, revelating generalized form of the disease. Rapid systemic treatment of GPA can protect hearing and facial nerve from permanent severe dysfunction. The ACR/EULAR 2017 provisional classification criteria for GPA seem to be valuable tool in diagnosing ENT patients with localized otological form of the disease., (© 2021. The Author(s).)

Background: To evaluate the epidemiology, management and outcome of acute mastoiditis (AM) in children and to improve strategies for antimicrobial stewardship., Methods: We conducted a retrospective observational study of children aged >6 months to ≤18 years of age admitted to a tertiary care hospital with AM over an 8-year period (2011-2019). Electronic medical records were reviewed to collect data., Results: A total of 129 patients met inclusion criteria for AM during this time period. Eighty-one (63 %) were males with 110 (81 %) White and 67 (52 %) non-Hispanic. The median age at presentation was 6.4 years (3-10.1 years). Ear protrusion was associated with reduced odds of having AM with intracranial extension (ICE) (OR 0.307, 95 % CI = 0.107-0.883) whereas presence of headaches and/or neck pain increased the odds of having AM with ICE (OR = 3.96, 95%CI 1.29-12.1). The most common etiologies were Streptococcus pyogenes (n = 23, 19.2 %), Pseudomonas aeruginosa (n = 20, 17 %), and Streptococcus pneumoniae (n = 15, 12.5 %). Empiric antibiotic selection and duration of therapy was highly variable. The most common empiric antibiotic used was intravenous vancomycin with a third generation cephalosporin (n = 45, 34.8 %). Majority completed course (n = 92; 73 %) with an oral antibiotic. Shorter (≤10 and ≤14 days) versus longer courses (>10 and >14 days) did not affect readmission rates for AM without ICE., Conclusion: There is high variability of treatment of AM in children. Broad spectrum antibiotics, especially vancomycin were used most frequently despite low rates of Methicillin Resistant Staphylococcus aureus. The use of antibiotic stewardship is essential for judicious antibiotic use., Competing Interests: Declaration of competing interest No conflicts of interest to disclose., (Copyright © 2022 Elsevier Inc.

Objective: The objective for this systematic review is to characterize clinical presentations of Bezold's abscesses to improve awareness and promote earlier diagnoses and prompt intervention in this increasingly rare otologic infection., Data Sources: Pubmed/Medline, CINAHL (EBSCOhost), and Web of Science articles in all languages were searched., Study Selection: Inclusion criteria were that the article was either a case report, case series, or retrospective review with individual case data available. Non-English articles were excluded if they lacked an English language abstract and if that abstract lacked information on baseline demographics, clinical presentation, and management., Data Extraction: Included studies were evaluated using fulltext review and demographics, etiology, microbiology, antibiotic usage, and surgical variables were collected., Data Synthesis: Data were qualitatively synthesized, with means and averages obtained for all continuous variables., Conclusions: Bezold's abscess remains a rare otologic infection, but they are relatively commonly associated with serious neurologic and systemic complications. Delay in diagnosis was a frequent commonality and diagnostic vigilance is tantamount in avoiding this sequelae.

Objectives: Sinus venous thrombosis (SVT) is a rare complication of acute otitis media (AOM) with acute mastoiditis (AM), which during recent years has been associated with Fusobacterium necrophorum (Fn) infection. Our objective was to review clinical, microbiologic, and hematologic features of paediatric otogenic SVT, with a specific focus on the role of Fn., Methods: A retrospective database review in a tertiary paediatric hospital between 2000-2019., Results: Fifty children aged 6-155 months were treated for AM with SVT. Forty-seven (94%) underwent cortical mastoidectomy. Forty-six children received low-molecular-weight heparin (LMWH). Follow-up imaging revealed recanalisation in 92% of cases. No long-term neurologic or haematologic complications were observed. Since 2014, when anaerobic cultures and PCR were routinely used in our institute, Fn was isolated from 15/21 children with SVT. Their time to recanalisation was longer, and the rate of lupus anticoagulant antibodies (LAC) was higher than in the 6 non-Fn patients. Children positive for LAC also had a longer time to recanalisation., Conclusions: Fn is a common pathogen in AM with SVT; its thrombogenic role was demonstrated by a higher prevalence of LAC and a longer time to recanalisation., (Copyright © 2022 Società Italiana di Otorinolaringoiatria e Chirurgia Cervico-Facciale, Rome, Italy.)

Purpose: To determine the immediate post-operative course and outcome of pediatric patients with complicated acute mastoiditis (CAM) following surgical treatment., Methods: A retrospective chart review of children diagnosed with CAM who underwent mastoid surgery during 2012-2019 in a tertiary care university hospital. 33 patients, divided into 2 groups: 17 patients with sub-periosteal abscess (SPA) alone-single complication group (SCG) and 16 patients with SPA and additional complications: sigmoid sinus thrombosis (SST), peri-sinus fluid/abscess, epidural/subdural abscess, and acute meningitis-multiple complications group (MCG)., Results: 33 patients belong to the SCG 17(51%) and 16(49%) belonged to the MCG, respectively. 6/17(35.3%) SCG patients experienced POF vs. 12/16(75%) in the MCG (P = 0.012). At post-operative day 2 (POD2), 10/13(77%) febrile patients belonged to MCG and 3/13(23%) to SCG (P = 0.013). POF was recorded until POD6 in both groups. Seven patients, all from MCG with POF, underwent second imaging with no new findings; a total of 18 positive cultures were reported. Fusobacterium necrophorum counted for 8/18(44.5%) of all positive cultures, 7/9(77.8%) in the MCG vs. 1/9(11.1%) in the SCG, P = 0.004. Streptococcus pneumoniae was reported only in SCG (5/9, 55.5%, vs. 0/9, P = 0.008)., Conclusion: Post-mastoidectomy fever due to CAM is not unusual and seems to be a benign condition for the first 5-6 days, following surgery. MCG patients are more prone to develop POF. F. necrophorum is more likely to be associated with MCG, and S. pneumoniae is common in SCG patients., (© 2021.

Introduction: Septic arthritis of the Temporomandibular joint (TMJ) is a rare complication of acute middle ear infection. Presentation is elusive and could be easily missed. Often diagnosis is made only with consequential development of TMJ ankylosis. This study intends to characterize patients and course of disease and suggest a diagnostic and therapeutic strategy., Methods: Retrospective review of all children diagnosed with TMJ arthritis and/or TMJ ankylosis secondary to acute middle ear infection, treated in a tertiary pediatric medical center between the years 2005 and 2021., Result: Seven patients were identified with otogenic TMJ arthritis. Median age at presentation was 1.14 years (IQ range 1.1-1.5). All seven were diagnosed with acute mastoiditis. CT scans demonstrated TMJ related collections in 5/7 and intracranial complications in 3/7. Treatment included cortical mastoidectomy for 5/7. One patient had a concomitant surgical washout of the TMJ. Two patients had drainage only of subperiosteal collections. Six of the seven patients went on to develop TMJ ankylosis that presented within a median of 2.8 years (IQ range 2.6-3.9) after the episode of acute mastoiditis. All six patients presented with trismus and facial growth anomalies, and all but one required surgery to release the ankylosis., Conclusion: Otogenic TMJ arthritis develops mostly in young children with acute mastoiditis and intratemproal and/or intracranial suppuration. Imaging is helpful in making the diagnosis, with TMJ related collections on CT being the most common finding. TMJ ankylosis can develop within a few years and present with trismus and abnormal facial growth. Cortical mastoidectomy does not seem to prevent ankylosis. It remains unclear whether focused treatment to the TMJ or physiotherapy could be beneficial in that., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Background: The objective of our study was to evaluate the efficacy of treatment options for the most frequently reported complications of acute mastoiditis in the English literature. PubMed, EMBASE, and The Cochrane Library were searched from database inception through March 29, 2019., Methods: Two independent reviewers (M.R.K., K.S.) evaluated search results for study inclusion. References cited in publications meeting inclusion criteria were reviewed. Twenty-three included studies were published from 1998 through 2018. Treatment efficacy was determined by comparing the change in number of complication subtypes in each treatment subgroup (medical, conservative, or surgical) from admission to discharge (range: 5-30 days) or postdischarge follow-up (range: 1-27.5 months) with a random effects model., Results: Among 733 identified articles, 23 met inclusion criteria. Of the 883 included patients, 203 were managed medically (23%), 300 conservatively (34%) and 380 surgically (43%). Conservative patients had more extracranial complications (ECC, P = 0.04) and intratemporal complications (IT, P = 0.04) at follow-up compared with medical patients. Medical patients had more total number of complications (TNC, P = 0.03), ECC (P = 0.02), and IT (P = 0.01) at discharge compared with surgical patients. Conservative patients had more of all complications except intracranial/extracranial abscess and "other" at discharge and follow-up compared with surgical patients., Conclusions: There were larger reductions in TNC, ECC, and IT at discharge and follow-up among surgical patients compared with medical and conservative patients. There were greater reductions in TNC, ECC, IT, intracranial complications, subperiosteal abscess and lateral sinus thrombosis at discharge and follow-up among surgical patients compared with conservative patients., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: We aimed to describe the clinical presentation, risk of bleeding and recurrent thrombosis, and perioperative anticoagulant management of children with cerebral venous thrombosis (CVT) and an associated head or neck infection., Methods: In this subgroup analysis of the EINSTEIN-Jr study, we included children with CVT and an associated head or neck infection who received therapeutic anticoagulants with either low-molecular-weight heparin (with or without subsequent vitamin K antagonists) or rivaroxaban for a period of 3 months. Analyses are descriptive., Results: Of 74 included children, 59 (80%) had otomastoiditis, 21 (28%) a central nervous system infection, 18 (24%) sinusitis, and 9 (12%) another upper respiratory tract infection; 29 (39%) had infection of multiple regions of the head or neck. All 74 children received antibiotics and therapeutic anticoagulants; 41 (55%) underwent surgery, of whom 34 were diagnosed with CVT preoperatively. Anticoagulation was started before surgery in 12 children and interrupted 0-1 days prior to surgery. Anticoagulation was (re)started in all 34 children at a median of 1 day (interquartile range: 0-1) postoperatively, in therapeutic doses in 94%. Overall, one child (1%, 95% confidence interval: 0-7) had recurrent thrombosis, and one (1%, 95% confidence interval: 0-7) had major bleeding; neither was associated with surgery. At 3 months, no children had died, 3 (4%) had persistent focal neurologic deficits, and 2 (3%) had impaired vision., Conclusions: Children with CVT and an associated head or neck infection administered therapeutic anticoagulants generally had low risks of bleeding and thrombotic complications, including those who had surgical interventions with delay or interruption of anticoagulation., (Copyright © 2021 The Author(s).

Purpose: Cerebral sinus vein thrombosis (CSVT) associated with acute mastoiditis is a rare complication of acute otitis media. Elevated intracranial pressure (ICP) frequently occurs secondary to CSVT. The study aims to review the 5 years of experience of four medical centres to treat sigmoid sinus thrombosis and elevated intracranial pressure in children., Methods: Patients with CSVT that developed secondary mastoiditis from 2016 through 2021 were evaluated in four centres from Turkey. Patients diagnosed with a preceding or synchronous mastoiditis and intracranial sinus thrombosis were included in the study. Magnetic resonance imaging (MRI), magnetic resonance venography (MRV), ICP measurements, ophthalmological examinations, thrombophilia studies and treatments for increased ICP have also been recorded., Results: The study group comprises 18 children. Twelve patients were diagnosed with right-sided, six patients with left-sided sinus vein thrombosis. All of the patients had ipsilateral mastoiditis. The most common presenting symptoms were fever, ear pain, headache, visual disorders and vomiting. The most encountered neurologic findings were papilledema, strabismus and sixth cranial nerve palsy. ICP was over 20 cm H 2 O in eleven patients. Anticoagulant treatment, antibiotics, pressure-lowering lumbar puncture and lumboperitoneal shunt were among the treatment modalities., Conclusion: Elevated ICP can damage the brain and optic nerve irreversibly, without treatment. For treating elevation of ICP associated with cerebral sinus thrombosis, pressure-lowering lumbar puncture (LP), acetazolamide therapy, optic nerve sheath fenestration (ONSF) and cerebrospinal fluid (CSF)-shunting procedures are suggested in case of deteriorated vision., (© 2021.

Background: Paediatric otogenic cerebral venous sinus thrombosis is a rare, heterogeneous and life-threatening condition, with possible otological, neurological and ophthalmological sequelae. Its course and outcomes can be widely variable. The publications available often consider individual aspects of paediatric otogenic cerebral venous sinus thrombosis management. The condition itself and the nature of the currently available guidance can lead to uncertainties when holistically managing patients with paediatric otogenic cerebral venous sinus thrombosis., Objectives: Clear recommendations for the comprehensive assessment and management of paediatric otogenic cerebral venous sinus thrombosis are presented, along with the literature review upon which they are based. Its clinical and radiological assessment are discussed., Conclusion: A multidisciplinary approach to assessment and management is recommended, inclusive of infectious diseases, ENT surgery, neurology, ophthalmology and haematology. On balance, anticoagulation is recommended for three months. Follow-up imaging is not recommended in the absence of clinical concern. Follow up by ENT surgery, neurology and ophthalmology departments is recommended.

A clinical case of diagnosis and treatment of an 8-year-old patient with bilateral acute suppurative otitis media (ASOM) complicated by left mastoiditis and petrositis is presented. By itself, such a rare complication of ASOM as petrositis manifested itself not in the form of the classic Gradenigo triad, but as a parapharyngeal abscess (PPA), due to the destruction of the lower wall of the temporal bone pyramid. Complications arose as a result of contact and hematogenous pathways for the spread of the infection, which debuted in the middle ear cavities 1 month before the patient was admitted to the hospital. The combination of factors such as an aggressive pathogen, the anatomical structure of the middle ear, a decrease in the immune reactivity of the child's body, the spread of infection through the lower cells of the temporal bone pyramid and the lack of timely antibiotic therapy, led to destructive changes in the bony walls of the temporal bone and the spread of a purulent process to the temporal pyramid bones, and then to the parapharyngeal space. The destruction by inflammation of the lower wall of the pyramid of the temporal bone led to the development of PPA, and not meningoencephalitis, which could have fatal consequences.

A 4-year-old boy was diagnosed with intracranial abscess following adequately treated otorrhea and mastoiditis. This is an uncommon finding. He underwent mastoidectomy with drainage of the abscess. In cases where patients clinically deteriorate during treatment for otorrhea and mastoiditis, further examination using CT-scan is recommended.

Objective: A small proportion of children with otitis media develop acute mastoiditis, which has the potential to spread intracranially and result in significant morbidity and mortality. The aim of this study was to evaluate the incidence and management of complications related to pediatric acute mastoiditis using a national database., Study Design: Retrospective review of 2016 Kids' Inpatient Database, part of the Healthcare Cost and Utilization Project., Setting: Academic, community, general, and pediatric specialty hospitals in the United States., Methods: International Classification of Diseases, Tenth Revision, Clinical Modification code H70.XXX was used to retrieve records for children admitted with a diagnosis of mastoiditis. Data included patient demographics, intracranial infections, procedures (middle ear drainage, mastoidectomy, and intracranial drainage), length of stay (LOS), and total charges., Results: In total, 2061 children aged ≤21 years were identified with a diagnosis of acute mastoiditis. Complications included subperiosteal abscess (6.90%), intracranial thrombophlebitis/thrombosis (5.30%), intracranial abscess (3.90%), otitic hydrocephalus (1.20%), encephalitis (0.90%), subperiosteal abscess with intracranial complication (0.60%), petrositis (0.60%), and meningitis (0.30%). Children with intracranial abscesses were more likely ( P < .001) to undergo myringotomy ± ventilation tube insertion (63.7%), mastoidectomy (53.8%), mastoidectomy with ventilation tube or myringotomy (42.5%), intracranial drainage procedure (36.3%), or all 3 key procedures (15.0%). Children with any type of intracranial complication had a significantly longer LOS ( P < .001) and higher total charges ( P < .001). Both a diagnosis of bacterial meningitis and undergoing an intracranial drainage procedure ( P < .001) contributed significantly to LOS and total charges., Conclusion: Patients with intracranial complications are more likely to undergo surgical procedures; however, there is still wide variability in practice patterns, illustrating that controversies in the management of otitis media complications persist.

The authors report a case of fungal otitis media complicated by extension of the infection into adjacent structures causing apical petrositis and subsequently involvement of the jugular foramen in a 71-year-old diabetic man. First described in 1907, Gradenigo's syndrome is a serious but rare clinical triad of acute otitis media, unilateral pain in the distribution of cranial nerve V (trigeminal) and ipsilateral cranial nerve VI (abducens) palsy that commonly presents without all three features and is therefore often missed. In this report, our patient was initially misdiagnosed as having a diabetic cranial neuropathy, and later he developed Vernet's syndrome. Despite aggressive surgical and medical management, he did poorly and died a few weeks later. Clinicians need to be aware of this serious and life-threatening complication of otitis media in high-risk individuals with diabetes or immunocompromised states, to allow early diagnosis and improved clinical outcomes., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

The complications of otomastoiditis are serious diseases, with a rapid unfavorable evolution in the absence or delay of the appropriate treatment. The urgent establishment of the diagnosis, with the differentiation of the types of complications that have arisen, is vital for determining the therapeutic decision, which is often difficult since there are still many controversies. There are presented several situations of otomastoiditis complications, each with their treatment particularities, the therapeutic decision being difficult to choose, most often coexisting with a mixed ENT-neurosurgical-infectionist management.

Aim: Diagnosis and management of complicated mastoiditis in childhood are still controversial. We investigated the clinical manifestations, evaluation and management of children with mastoiditis complicated with cerebral venous sinus thrombosis., Methods: Retrospective cohort study that included all children admitted for acute mastoiditis over the last 5 years. Children were divided in two groups based on the presence or not of venous sinus thrombosis. Clinical, laboratory, imaging and management data were retrieved and compared., Results: Overall, 20 children with acute mastoiditis were included, of whom 5 had magnetic resonance imaging-confirmed cerebral venous sinus thrombosis and elevated intracranial pressure (ICP). In all complicated cases, neurological signs rather than mastoiditis signs, prevailed. The more prominent neurologic signs observed were lethargy (60%), nuchal rigidity (60%), abducens nerve palsy (60%) and ataxic gait (20%). Treatment consisted of intravenous antibiotics combined with anticoagulation. Surgery was performed in four children (4/5). Complicated cases had prolonged symptoms prior to admission (p 0.002), presented with neurologic signs and symptoms (p < 0.001), underwent more often lumbar puncture (p < 0.001) and brain imaging (p < 0.001), and were treated with prolonged courses of antibiotics and surgery (<0.001), compared to children with uncomplicated mastoiditis., Conclusion: Neurological signs and symptoms and elevated ICP dominate in children with mastoiditis complicated with thrombosis. Brain imaging is essential for early diagnosis of cerebral venous sinus complications and appropriate management., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Objectives/hypothesis: To describe the presentation and management of acute complicated mastoiditis in children.Study Design: Retrospective case series.Methods: An analysis of pediatric patients with acute complicated mastoiditis treated at an urban, tertiary care children's hospital from 2007 to 2014 was performed.Results: Forty-eight patients presented with a total of 67 complications of acute mastoiditis. Mean age at presentation was 4.8 years (range = 0.1-15.3 years). The most common complications were subperiosteal abscess (n = 22, 45.8%), epidural abscess (n = 16, 33.3%), and sigmoid sinus thrombosis (n = 14, 29.2%). The most common pathogens isolated included Streptococcus pneumoniae (n = 14, 29.2%) and group A streptococcus (n = 10, 20.8%). Multidrug resistance was not associated with complication type. Surgical management included myringotomy ± tympanostomy tube placement in 46 (95.8%) patients (the only surgery in 10), drainage of subperiosteal abscess without mastoidectomy in 18 (37.5%) patients, and mastoidectomy in 21 (43.8%) total patients. Patients presenting with intracranial complications were the most likely to undergo a mastoidectomy. Anticoagulation was used in the management of nine of 14 (64.3%) patients presenting with sigmoid sinus thrombosis. Neurosurgical interventions (n = 7, 14.6% patients) were primarily performed to manage increased intracranial pressure.Conclusions: Subperiosteal abscess was the most common complication of acute mastoiditis, and when occurring as the sole complication was successfully managed with antibiotics and surgical intervention that did not include mastoidectomy. Epidural abscess and sigmoid sinus thrombosis were more prevalent than reported in prior series and were managed more aggressively. These patients were more likely to need neurosurgical interventions.Level Of Evidence: 4. Laryngoscope, 127:2321-2327, 2017. [ABSTRACT FROM AUTHOR]

Objective: The incidence of complications due to acute otitis media (AOM) in childhood has decreased significantly with the use of new antibiotics in recent years. However, acute mastoiditis (AM) is still the most common complication that can lead to further intracranial conditions with high morbidity. Our study aimed to evaluate the clinical characteristics of children with AM and identify possible indicators for further intracranial complications associated with this condition., Methods: Children hospitalized in our clinic with a diagnosis of AM were reviewed. Demographic data, disease-related symptoms, types of complications accompanied by AM, medical/surgical treatments modalities, and culture results were screened. The patients were divided into two groups as those with and without intracranial complications (ICCs). Routine complete blood count tests, biochemical analysis, and C-reactive protein (CRP) level measurement were evaluated and compared between the groups., Results: Of the 28 AM patients, five (17.9%) had isolated AM. Complications associated with AM included sub-periosteal abscess (28.6%), facial paralysis (25%), meningitis (17.9%), meningitis with sigmoid sinus thrombosis (7.1%), and meningitis with cerebellar abscess (3.6%). Eight patients developed ICCs (28.6%), of whom three had more than one complication. Ceftriaxone was found to be the first-line medical treatment (57.1%). Streptococcus pneumoniae was the most common pathogen isolated from the cultures (42.9%). Three patients (10.7%) were treated non-surgically, eight (28.6%) with myringotomy and ventilation tube (VT) insertion, eight patients (28.6%) with abscess drainage and VT insertion, and nine (32.1%) with cortical mastoidectomy and VT insertion. There was no significant difference between the patients with and without ICCs in terms of complete blood count parameters. The CRP level and the CRP-albumin ratio were significantly higher in patients with ICCs than those without these complications (p < 0.001)., Conclusion: AM remains to be the most common complication of AOM in childhood and can lead to further life-threatening conditions. Additional interventions according to the type of the complication with VT insertion is safe and effective in the management of AM. In patients with AM, it is of great importance to determine whether there is an accompanying ICC. The CRP-albumin ratio is a simple and reliable calculation to detect ICCs in patients with AM., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Aim: We aimed to describe otogenic lateral sinovenous thrombosis (OLST), a rare, potentially life-threatening complication of otomastoiditis., Methods: Children diagnosed with OLST in a tertiary-care Hospital from 2014 to 2019 was retrospectively selected. Clinical and radiological features, timing of diagnosis, treatment and outcome are reported., Results: Seven children (5 males) were studied. Fever and neurological symptoms (headache, lethargy, diplopia, dizziness and papilledema) were always present. Otalgia and/or otorrhea were found in 6 children; none had signs of mastoiditis. Diagnosis was reached after 7 days (median) from clinical onset. Brain CT-scan was performed in 5 children being diagnostic for 3. Venography-MRI detected OLST and mastoiditis in all cases without parenchymal lesions. Treatment was based on intravenous rehydration, antibiotic and low-molecular weight heparin; acetazolamide was added in 3 children. Mastoidectomy and ventriculoperitoneal-shunting were selectively performed. Patients were discharged after 26 days (median). Follow-up neuroimaging showed sinus recanalization after a median time of 6 months., Conclusion: A multidisciplinary approach is needed to optimize diagnostic-therapeutic protocols of pediatric OLST., Competing Interests: Declaration of Competing Interest The authors declare no potential conflict of interest with respect to the research, authorship and/or publication of this article., (Copyright © 2020 Elsevier Inc.

Background: Cerebral venous sinus thrombosis in children is a rare but potentially fatal complication of acute mastoiditis, one of the most common pediatric infectious diseases. Due to its subtle clinical presentation, suspicion is essential for a prompt diagnosis and appropriate management. Unfortunately, no standard treatment options are available. To discuss the possible clinical presentation, microbiology, and management, we here report the case of a child with otogenic cerebral venous sinus thrombosis and perform a literature review starting from 2011., Case Presentation: The child, a 10-months-old male, presented clinical signs of right acute otitis media and mastoiditis. Brain computed tomography scan detected right sigmoid and transverse sinus thrombosis, as well as a subperiosteal abscess. Fusobacterium necrophorum and Haemophilus Influentiae were detected on cultural sampling. A multidisciplinary approach along with a combination of medical and surgical therapy allowed the patient's full recovery., Conclusion: Cerebral venous sinus thrombosis is a rare but severe complication of acute otitis media and mastoiditis. The management of this pathological condition is always challenging and an interdisciplinary approach is frequently required. Current therapeutic options include a combination of medical and surgical therapy. A patient-centered approach should guide timing and treatment management.

Objective: Bibliographic data for the management of acute mastoiditis in infants aged six months or less are very limited. This study investigated the presenting symptomatology, diagnostic and treatment options, and final outcomes in this age group., Method: A retrospective review was conducted of all infants aged six months or less suffering from acute mastoiditis, admitted to our department between 2007 and 2017., Results: Eleven infants were identified. All of them developed the typical symptomatology of acute mastoiditis, while a higher rate of subperiosteal abscess formation was observed. Imaging was necessary in three cases only. Parenteral antibiotics and myringotomy were applied in all infants. A drainage procedure was also included in the infants with a subperiosteal abscess. Antrotomy was reserved for non-responsive cases. No intracranial complications were observed. All infants were cured without further complications or sequelae., Conclusion: Acute mastoiditis in infants aged six months or less can be safely diagnosed and treated using a standardised algorithmic approach, similar to that used for older children.

Background: Mastoiditis is the most common intra-temporal complication of acute otitis media. Despite potentially lethal sequelae, optimal management remains poorly defined., Method: A retrospective case review was conducted of children diagnosed with mastoiditis at a tertiary referral centre, in North East England, between 2010 and 2017., Results: Fifty-one cases were identified, 49 without cholesteatoma. Median patient age was 42 months (2 months to 18 years) and median hospital stay was 4 days (range, 0-27 days). There was no incidence trend over time. Imaging was conducted in 15 out of 49 cases. Surgery was performed in 29 out of 49 cases, most commonly mastoidectomy with (9 out of 29) or without (9 out of 29) grommets. Complications included sigmoid sinus thrombosis (3 out of 49) and extradural abscess (2 out of 51), amongst others; no fatalities occurred., Conclusion: A detailed contemporary description of paediatric mastoiditis presentation and management is presented. The findings broadly mirror those published by other UK centres, but suggest a higher rate of identified disease complications and surgical interventions.

Gradenigo's Syndrome is a rare complication of otitis media and/or mastoiditis resulting in inflammation of the petrous apex of the temporal bone. Here, we highlight an interesting case from our institution, summarize available pediatric cases from the past fifty years to provide an updated diagnostic categorization for this rare condition with confusing nomenclature, and suggest guidance for diagnosis and management., Competing Interests: Declaration of competing interest The authors do not have any conflicts of interest to disclose relevant to this work., (Copyright © 2020 Elsevier B.V.

Objectives: Luc's abscess is a rare complication of acute otitis media, with a challenging diagnosis and a controversial surgical treatment. The aim of the present study was to review the published literature in order to clarify the clinical features and the surgical management of those patients., Methods: A systematic review of the literature was carried out for published reports or case series in English language, describing a temporo-zygomatic (or Luc's) abscess which complicated an acute or chronic otitis media and/or mastoiditis, confirmed through CT scan or MRI of the petrous bone. The collected clinical and radiological data were merged and critically appraised., Results: Eighteen reports of Luc's abscess were included. Adding our case report, a total of 21 cases were included in the analysis. Abscess drainage plus myringotomy alone vs. abscess drainage plus myringotomy and mastoidectomy were the two surgical management approaches described in the literature. Patients undergoing first line mastoidectomy were successfully treated in all cases, while among those undergoing a more conservative approach, one failure required subsequent mastoidectomy., Conclusions: The clinical features of Luc's abscess are rather constant and help in rising the suspicion before the radiological diagnosis. Although cases with associated intra-cranic complications have been reported, the limited existing data do not permit to advocate the mastoidectomy over a more conservative surgical approach. However, the decision to avoid mastoidectomy as the first line surgical treatment should be based on the clinical and radiologic assessment, after an accurate counseling, particularly in the case of a pediatric patient., Competing Interests: Declaration of Competing Interest None., (Copyright © 2019.

Acute mastoiditis is an infection that affects the mastoid air-cell system, usually due to the progression of an acute otitis media. The bacteria most frequently isolated in acute mastoiditis are Streptococcus pneumoniae, Streptococcus pyogenes and Staphylococcus aureus. The mastoid infection can extend affecting contiguous structures and producing intra or extracranial complications. The most frequent ones are intracranial complications, including meningitis, temporal lobe or cerebellar abscess, epidural or subdural abscess and venous sinus thrombosis. We present the case of a 4-year-old girl who developed two intracranial complications (intracranial epidural abscess and transverse and sigmoid sinus thrombosis) initiated in an acute mastoiditis produced by Streptococcus pyogenes., Competing Interests: The authors report no conflicts of interest in this work., (Sociedad Argentina de Pediatría.)

Objective: To evaluate in children the clinical severity and evolution of otogenic lateral sinus thrombosis (OLST) due to Fusobacterium necrophorum compared with other bacterial otogenic thrombosis and propose a specific management flowchart for Fusobacterium OLST., Design: A retrospective multicentre cohort study., Settings: Four French ENT paediatric departments., Participants: A total of 260 under 18 years old admitted for acute mastoiditis were included. Initial imaging was reviewed to focus on complicated mastoiditis and 52 OLST were identified. Children were then divided into two groups according to bacteriological results: 28 in the "OLST Fusobacterium group" and 24 in the "OLST other bacteria group"., Results: There was a significant association between F necrophorum and OLST (P < .001). When compared to the OLST other bacteria group, children in the OLST Fusobacterium group were significantly younger (61 months vs 23 months, P < .01) and had a more severe clinical presentation: higher CRP (113 mg/L vs 175.7 mg/L, P = .02) and larger subperiosteal abscess (14 mm vs 21 mm, P < .01). Medical management was also more intensive in the OLST Fusobacterium group than in the OLST other bacteria group: increased number of conservative surgeries (66.7% vs 92.9%, P = .03) and longer hospital stay (13.7 days vs 19.8 days, P = .02). At the end of follow-up, the clinical course was good in both groups without any neurological sequelae., Conclusions: Thrombotic complications are very frequent in case of Fusobacterium mastoiditis and clinicians should be aware of the initial severity of the clinical presentation. Under appropriate management, the clinical course of Fusobacterium OLST is as good as that of other bacterial otogenic thrombosis., (© 2019 John Wiley & Sons Ltd.)
