IntroductionThe physical modification of cartilage grafts during rhinoplasty risks chondrocyte death at the margins where the tissue is cut. This study compares chondrocyte viability between diced, scaled, and pate samples in human models, and further computes percent chondrocyte viability as a function of sequential dicing size in a computational model.MethodsSeptal cartilage from 11 individuals was prepared as follows: diced (1 mm cubic), scaled (shaved to  0.05). Conversely, pate samples had significantly less viability compared to positive controls, diced samples, and scaled samples (all p

Objectives  Head and neck mucosal melanoma (HNMM) is a rare malignancy with high mortality. This study evaluates the impact of treatment delays on overall survival in HNMM. Design/Setting/Participants  A retrospective review of patients with surgically managed HNMM treated with adjuvant radiation was performed from the 2004-2016 National Cancer Database. Main Outcome Measures  Durations of diagnosis-to-treatment initiation (DTI), surgery-to-radiotherapy initiation (SRT), duration of radiotherapy (RTD), surgery-to-immunotherapy initiation (SIT), diagnosis-to-treatment end (DTE), and total treatment package (TTP) were calculated. Results  A total of 1,011 patients (50.7% female, 90.5% Caucasian) met inclusion criteria. Median DTI, SRT, RTD, SIT, DTE, and TTP were 30, 49, 41, 102, 119, and 87 days, respectively. Only longer DTE was associated with decreased mortality (hazard ratio, 0.720; 95% confidence interval, 0.536-0.965; p  = 0.028). Conclusion  DTI, SRT, RTD, SIT, and TTP do not significantly affect overall survival in patients with HNMM who undergo surgery and adjuvant radiation. Longer DTE is associated with improved survival in this population. Level of Evidence  4.

ObjectiveDrug induced sleep endoscopy (DISE) is often performed for pediatric obstructive sleep apnea (OSA) when initial diagnostic studies do not provide adequate information for therapy. However, DISE scoring is subjective and with limitations. This proof-of-concept study demonstrates the use of a novel long-range optical coherence tomography (LR-OCT) system during DISE of two pediatric patients.MethodsLR-OCT was used to visualize the airway of pediatric patients during DISE. At the conclusion of DISE, the OCT probe was guided in the airway under endoscopic visual guidance, and cross-sectional images were acquired at the four VOTE locations. Data processing involved image resizing and alignment, followed by rendering of three-dimensional (3D) volumetric models of the airways.ResultsTwo patients were included in this study. Patient one had 18.4%, 20.9%, 72.3%, and 97.3% maximal obstruction at velum, oropharynx, tongue base, and epiglottis, while patient two had 40.2%, 41.4%, 8.0%, and 17.5% maximal obstruction at these regions, respectively. Three-dimensional reconstructions of patients' airways were also constructed from the OCT images.ConclusionThis proof-of-concept study demonstrates the successful evaluation of pediatric airway during DISE using LR-OCT, which accurately identified sites and degrees of obstruction with respective 3D airway reconstruction.

Background: Many open-access artificial intelligence (AI)-based websites that rate facial attractiveness are available, but none have been compared with human focus group outcomes. Objective: To compare human and AI-based websites scoring of facial attractiveness of adult female white faces. Methods: A 40-photograph database of AI-generated adult, white, female, expressionless, and frontal-view facial images were scored by otolaryngology residents and five AI-based facial rating websites: prettyscale.com, attractivenesstest.com, face-score.com/en, hotchat3000.com, and beautyscoretest.com. Sample t-test and bivariate correlation were performed for statistical analyses. Results: The focus group of 24 otolaryngology residents consisted of 62.5% males and 58.3% white participants. There was a strong positive correlation between average human score and average AI score for each photo (Pearson's correlation 0.84, p

ObjectivesTo evaluate the effectiveness of triamcinolone injections in treating external magnet displacement in cochlear implant (CI) patients with adhesions problems of their processor.PatientsWe present seven CI patients with magnet adhesion issues who presented to our tertiary care neurotology clinic. None of the patients had a history of head trauma, postimplant MRI, or surgery in the head and neck other than the cochlear implantation.InterventionTriamcinolone 40 mg/mL injected subcutaneously at the CI magnet site.Main outcome measureReduction of scalp thickness and successful magnet retention.ResultsOur cohort consisted of seven patients (eight implant sites) of which five were overweight or obese. The temporoparietal scalp thickness measured on preoperative CT scans varied between 8.4 and 15.9 mm. Initial conservative measures such as hair shaving at the magnet site, using a headband, and increasing magnet strength failed in all patients. After receiving triamcinolone injections at the CI receiver site, six out of seven patients (seven out of eight CI sites) were able to use their processor again without the need for a headband for an average of 9.55 hours/day. The average number of injections required for each patient was 2.57 (SD = 2.18), median (range) = 1 (1-7). One patient required a flap thinning surgery but showed no improvement even after flap thinning. None of the patients showed skin irritation, breakdown, ulceration, necrosis, or magnet exposure during follow-up period.ConclusionsThe significant improvement in CI retention shows that triamcinolone injections are effective in making the subcutaneous tissue thinner and allowing magnet retention.

BackgroundAcute invasive fungal sinusitis (AIFS) is an aggressive disease that requires prompt diagnosis and multidisciplinary treatment given its rapid progression. However, there is currently no consensus on diagnosis, prognosis, and management strategies for AIFS, with multiple modalities routinely employed. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on AIFS, summarize the existing evidence, and provide recommendations on the management of AIFS.MethodsThe PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through January 2022. Studies evaluating management for orbital, non-sinonasal head and neck, and intracranial manifestations of AIFS were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on management principles for AIFS were generated.ResultsA review and evaluation of published literature was performed on 12 topics surrounding AIFS (signs and symptoms, laboratory and microbiology diagnostics, endoscopy, imaging, pathology, surgery, medical therapy, management of extrasinus extension, reversing immunosuppression, and outcomes and survival). The aggregate quality of evidence was varied across reviewed domains.ConclusionBased on the currently available evidence, judicious utilization of a combination of history and physical examination, laboratory and histopathologic techniques, and endoscopy provide the cornerstone for accurate diagnosis of AIFS. In addition, AIFS is optimally managed by a multidisciplinary team via a combination of surgery (including resection whenever possible), antifungal therapy, and correcting sources of immunosuppression. Higher quality (i.e., prospective) studies are needed to better define the roles of each modality and determine diagnosis and treatment algorithms.

ObjectivesThe objective of this study is to understand whether the hearing loss laterality in Menière's disease (MD) correlates with migraine symptoms laterality such as headache, neck stiffness, and otalgia.MethodsWe performed a retrospective review of prospectively obtained data on patients presenting between September 2015 and October 2021 with definite or probable MD. A custom-designed, comprehensive questionnaire was used to identify patients' migraine-related symptoms. The clinical and audiometric data were used to diagnose patients with definite or probable MD using criteria set by the American Academy of Otolaryngology-Head and Neck Surgery.ResultsIn total, 113 patients with definite or probable MD were included in the study. The mean age of the patients was 60 ± 15 years with no gender predominance (49.6% male and 50.4% female). A total of 57 (50%) patients were presented with headaches. Among the migraine headache cohort, headache and otalgia were on the same side as the MD ear affected by hearing loss. In addition, in patients who present with otalgia as the primary feature of headache, otalgia was more likely to be on the same side as the ear affected by the hearing loss.ConclusionsThe high prevalence of migraine symptoms on the same side of the ear affected by MD among this cohort could suggest a shared pathophysiology in both MD and migraine, possibly involving migraine-related changes in both the cochlea and vestibule.

OBJECTIVES: To evaluate the influence of facility case-volume on survival in patients with locally advanced papillary thyroid cancer (PTC), and to identify prognostic case-volume thresholds for facilities managing this patient population. STUDY DESIGN: Retrospective database study. METHODS: The 2004-2017 National Cancer Database was queried for patients receiving definitive surgery for locally advanced PTC. Using K-means clustering and multivariable Cox proportional-hazards (CPH) regression, two groups with distinct spectrums of facility case-volumes were generated. Multivariable CPH regression and Kaplan-Meier analysis assessed for the influence of facility case-volume and the prognostic value of its stratification on overall survival (OS). RESULTS: Of 48,899 patients treated at 1304 facilities, there were 34,312 (70.2%) females and the mean age was 48.0 ± 16.0 years. Increased facility volume was significantly associated with reduced all-cause mortality (HR 0.996; 95% CI, 0.992-0.999; p = 0.008). Five facility clusters were generated, from which two distinct cohorts were identified: low (LVF;

Objectives  Skull base chordomas are locally aggressive malignant tumors derived from the notochord remnant. There are limited large-scale studies examining the role and extent of surgery and radiation therapy. Design  Analysis of the National Cancer Database (NCDB) was performed to evaluate the survival outcomes of various treatments, and to assess for predictors of overall survival (OS). Participants  This is a retrospective, population-based cohort study of patients diagnosed with a clival/skull base chordoma between 2004 and 2015 in the NCDB. Main Outcome Measures  The primary outcome was overall survival (OS). Results  In all, 468 cases were identified. Forty-nine percent of patients received surgery and 20.7% had positive margins. Mean age at diagnosis was 48.4 years in the surgical cohort, and 55% were males. Of the surgical cohort, 33.8% had negative margins, 20.7% had positive margins, and 45.5% had unknown margin status. Age ≥ 65 (hazard ratio [HR]: 3.07; 95% confidence interval [CI]: 1.63-5.76; p  5 cm (HR: 2.29; 95% CI: 1.26-4.15; p  = 0.007), and government insurance (HR: 2.28; 95% CI: 1.24-4.2; p  = 0.008) were independent predictors of OS. When comparing surgery with or without adjuvant radiation, no survival differences were found, regardless of margin status ( p  = 0.66). Conclusion  Surgery remains the mainstay of therapy. Advanced age (>65 years), large tumor size, and government insurance were predictors of worse OS. Whereas negative margins and the use of adjuvant radiation did not appear to impact OS, these may very well reduce local recurrences. A multidisciplinary approach is critical in achieving optimal outcomes in this challenging disease.

OBJECTIVE: To evaluate the prognostic strengths of American Joint Committee on Cancer (AJCC) staging and American Thyroid Association (ATA) risk classification in well-differentiated thyroid cancer (DTC), and their implications in guiding medical decision-making and epidemiological study designs. METHODS: The 2004-2017 National Cancer Database was queried for DTC patients. Cox proportional hazards (CPH) and Kaplan-Meier analyses modeled patient mortality and overall survival, respectively. Each CPH model was evaluated by its concordance index, measure of explained randomness (MER), Akaike information criterion (AIC), and area under receiver operating characteristic curve (AUC). RESULTS: Overall, 134,226 patients were analyzed, with an average age of 48.1 ± 15.1 years (76.9% female). Univariate CPH models using AJCC staging demonstrated higher concordance indices, MERs, and AUCs than those using ATA risk classification (all p

ObjectiveTo determine the implications of obesity on postoperative adverse events following skull base surgery.MethodsThe 2005-2017 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for adverse events in skull base surgery cases. Patients were stratified by body mass index (BMI) into normal weight (18.5 ≤ BMI  .05). On propensity score-adjusted multivariable analysis, only bleeding (OR = 0.42, P  .05).ConclusionsObesity was associated with decreased postoperative bleeding and increased deep vein thromboses. Obese patients were otherwise at no higher risk for medical or surgical complications. Elevated BMI did not confer an increased risk for readmission, reoperation, or death. Thus, patient obesity should not be a major determinant in offering skull base surgery in individuals who would otherwise benefit from treatment.

ObjectiveTo investigate the use of near-infrared (NIR) imaging as a tool for outpatient clinicians to quickly and accurately assess for maxillary sinusitis and to characterize its accuracy compared to computerized tomography (CT) scan.MethodsIn a prospective investigational study, NIR and CT images from 65 patients who presented to a tertiary care rhinology clinic were compared to determine the sensitivity and specificity of NIR as an imaging modality.ResultsThe sensitivity and specificity of NIR imaging in distinguishing normal versus maxillary sinus disease was found to be 90% and 84%, normal versus mild maxillary sinus disease to be 76% and 91%, and mild versus severe maxillary sinus disease to be 96% and 81%, respectively. The average pixel intensity was also calculated and compared to the modified Lund-Mackay scores from CT scans to assess the ability of NIR imaging to stratify the severity of maxillary sinus disease. Average pixel intensity over a region of interest was significantly different (P < .001) between normal, mild, and severe disease, as well as when comparing normal versus mild (P < .001, 95% CI 42.22-105.39), normal versus severe (P < .001, 95% CI 119.43-174.14), and mild versus severe (P < .001, 95% CI 41.39-104.56) maxillary sinus disease.ConclusionBased on this data, NIR shows promise as a tool for identifying patients with potential maxillary sinus disease as well as providing information on severity of disease that may guide administration of appropriate treatments.

Facial nerve (FN) injury can lead to debilitating and permanent facial paresis/paralysis (FP), where facial muscles progressively lose tone, atrophy, and ultimately reduce to scar tissue. Despite considerable efforts in the recent decades, therapies for FP still possess high failure rates and provide inadequate recovery of muscle function. In this pilot study, we used a feline model to demonstrate the potential for chronically implanted multichannel dual-cuff electrodes (MCE) to selectively stimulate injured facial nerves at low current intensities to avoid stimulus-induced neural injury. Selective facial muscle activation was achieved over six months after FN injury and MCE implantation in two domestic shorthaired cats (Felis catus). Through utilization of bipolar stimulation, specific muscles were activated at significantly lower electrical currents than was achievable with single channel stimulation. Moreover, interval increases in subthreshold current intensities using bipolar stimulation enabled a graded EMG voltage response while maintaining muscle selectivity. Histological examination of neural tissue at implant sites showed no appreciable signs of stimulation-induced nerve injury. Thus, by selectively activating facial musculature six months following initial FN injury and MCE implantation, we demonstrated the potential for our neural stimulator system to be safely and effectively applied to the chronic setting, with implications for FP treatment.

ObjectivesFacial paralysis is a debilitating condition with substantial functional and psychological consequences. This feline-model study evaluates whether facial muscles can be selectively activated in acute and chronic implantation of 16-channel multichannel cuff electrodes (MCE).MethodsTwo cats underwent acute terminal MCE implantation experiments, 2 underwent chronic MCE implantation in uninjured facial nerves (FN) and tested for 6 months, and 2 underwent chronic MCE implantation experiments after FN transection injury and tested for 3 months. The MCE were wrapped around the main trunk of the skeletonized FN, and data collection consisted of EMG thresholds, amplitudes, and selectivity of muscle activation.ResultsIn acute experimentation, activation of specific channels (ie, channels 1-3 and 6-8) resulted in selective activation of orbicularis oculi, whereas activation of other channels (ie, channels 4, 5, or 8) led to selective activation of levator auris longus with higher EMG amplitudes. MCE implantation yielded stable and selective facial muscle activation EMG thresholds and amplitudes up to a 5-month period. Modest selective muscle activation was furthermore obtained after a complete transection-reapproximating nerve injury after a 3-month recovery period and implantation reoperation. Chronic implantation of MCE did not lead to fibrosis on histology. Field steering was achieved to activate distinct facial muscles by sending simultaneous subthreshold currents to multiple channels, thus theoretically protecting against nerve damage from chronic electrical stimulation.ConclusionOur proof-of-concept results show the ability of an MCE, supplemented with field steering, to provide a degree of selective facial muscle stimulation in a feline model, even following nerve regeneration after FN injury.Level of evidenceN/A.

ObjectiveTo review overall survival (OS), recurrence patterns, and prognostic factors of de novo sinonasal squamous cell carcinoma (DN-SCC).Data sourcesPubMed, Scopus, OVID Medline, and Cochrane databases from 2006 to December 23, 2020.Review methodsThe study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Articles were required to report either recurrence patterns or survival outcomes of adults with DN-SCC. Case reports, books, reviews, meta-analyses, and database studies were all excluded.ResultsForty-one studies reported on survival or recurrence outcomes. The aggregate 5-year OS was 54.5% (range, 18%-75%) from 35 studies (n = 1903). Patients undergoing open surgery were more likely to receive radiation therapy and present at an advanced stage compared to those receiving endoscopic surgery (all P < .001). Advanced T stage, presence of cervical nodal metastases, maxillary sinus primary site, and negative human papillomavirus (HPV) status were all correlated with significantly worse 5-year OS. Direct meta-analysis of 8 studies demonstrated patients with surgery were more likely to be alive at 5 years compared to those who did not receive surgery (odds ratio, 2.26; 95% CI, 1.48-3.47; P < .001). Recurrence was reported in 628 of 1471 patients from 26 studies (42.7%) with an aggregate 5-year locoregional control rate of 67.1% (range, 50.4%-93.3%).ConclusionThis systematic review and meta-analysis suggests that the 5-year OS rate for DN-SCC may approach 54.5% and recurrence rate approaches 42.7%. In addition, various tumor characteristics including advanced T stage, positive nodal status, maxillary sinus origin, and negative HPV status are all associated with decreased survival.

BackgroundNasopharyngeal swab testing, which has greatly increased in utilization due to the COVID-19 pandemic, is generally safe and well-tolerated, although it may be rarely associated with adverse events.MethodsPublicly reported adverse events associated with nasopharyngeal COVID-19 testing within the Manufacturer and User Facility Device Experience (MAUDE) database and the published literature were queried.ResultsA total of 129 adverse events were reported, including 66 from the MAUDE database and 63 from literature review. The most common complications were swab fracture resulting in retained foreign body (47%), followed by epistaxis (17%), and headache (11%). Seven (12%) of the reported retained foreign body cases required removal under general anesthesia, while 1 (5%) of the epistaxis cases required surgical intervention. The most serious adverse event was meningitis following cerebrospinal fluid leak.ConclusionsPatients and healthcare providers should be aware of the potential risks associated with testing, with attention to ensuring proper technique, and be prepared to recognize and manage adverse events.

We characterized the clinical and sociodemographic factors predictive of surgery refusal in pituitary adenoma (PA) patients. We queried the National Cancer Database (NCDB) to identify adult PA patients treated from 2004−2015 receiving or refusing surgery. Multivariate logistic regression and Cox proportional-hazards analysis identified clinical and/or sociodemographic factors predictive of surgery refusal or mortality, respectively. Of the 34,226 patients identified, 280 (0.8%) refused surgery. On multivariate logistic regression, age > 65 (OR: 2.64; p < 0.001), African American race (OR: 1.70; p < 0.001), Charlson-Deyo Comorbidity (C/D) Index > 2 (OR: 1.52; p = 0.047), and government insurance (OR: 2.03; p < 0.001) or being uninsured (OR: 2.16; p = 0.03) were all significantly associated with surgery refusal. On multivariate cox-proportional hazard analysis, age > 65 (HR: 2.66; p < 0.001), tumor size > 2 cm (HR: 1.30; p < 0.001), C/D index > 1 (HR: 1.53; p < 0.001), having government insurance (HR: 1.66; p < 0.001) or being uninsured (HR: 1.67; p < 0.001), and surgery refusal (HR: 2.28; p < 0.001) were all significant predictors of increased mortality. Macroadenoma patients receiving surgery had a significant increase in overall survival (OS) compared to those who refused surgery (p < 0.001). There are significant sociodemographic factors that influence surgery refusal in PA patients. An individualized approach is warranted that considers functional status, clinical presentations, and patient choice.

Objectives/hypothesisThis study utilizes a large population national database to comprehensively analyze prognosticators and overall survival (OS) outcomes of varying treatment modalities in a large cohort of sinonasal diffuse large B-cell lymphoma (SN-DLBCL) patients.Study designRetrospective database study.MethodsThe National Cancer Database was queried for all SN-DLBCL cases diagnosed from 2004 to 2015. Kaplan-Meier log-rank test determined differences in OS based on clinical covariates. Cox proportional-hazards analysis was used to determine clinical and sociodemographic covariates predictive of mortality.ResultsA total of 2,073 SN-DLBCL patients were included, consisting of 48% female with a mean age of 66.0 ± 16.2 years. Overall, 82% of patients were Caucasian, 74% had early-stage disease, and 49% had primary tumors in the paranasal sinuses. Early-stage patients were more likely to receive multi-agent chemoradiotherapy compared to multi-agent chemotherapy alone (P

BackgroundNo study to date has analyzed the progression of sinonasal symptoms over time in COVID-19 patients. The purpose of this study is to analyze the progression of sinonasal symptoms and risk factors for olfactory dysfunction in the mild severity COVID-19 patient.MethodsAn internet survey was used to assess sinonasal symptoms in patients with COVID-19. Changes in rhinologic domain and symptom-specific Sinonasal Outcome Test (SNOT-22) scores were compared at five time points: two weeks before diagnosis, at diagnosis, two weeks after diagnosis, four weeks after diagnosis, and six months after diagnosis.Results521 responses were collected. Rhinologic domain SNOT-22 scores increased significantly (p  0.999). Taste-specific SNOT-22 scores also peaked at diagnosis (2.06, p  0.999). There were no significant differences in sense of smell or taste between 1-month and 6-month timepoints.ConclusionSinonasal symptoms, particularly loss of smell and taste, may be important presenting symptoms in the mild severity COVID-19 patient. Our findings support incorporating these symptoms into screening protocols.Level of evidence4.

ObjectivesTo investigate whether migraine is independently associated with tinnitus and subjective hearing loss (HL) in a large national database.MethodsThe de-identified 1999 to 2004 National Health and Nutrition Examination Survey database was retrospectively queried for subjects aged 18 to 65. HL and tinnitus were subjectively reported by subjects.ResultsA total of 12,962 subjects (52.9% female) with a mean age of 38.1 ± 14.6 years were included. This consisted of 2,657 (20.5%), 2,344 (18.1%), and 2,582 (19.9%) subjects who had migraine, subjective-HL, and tinnitus, respectively. In patients with tinnitus or subjective-HL, migraine was reported in 35.6% and 24.5%, respectively. Migraineurs were more likely to have subjective-HL (25.0% vs. 16.6%, p

ObjectivesTo develop a multiclass-classifier deep learning model and website for distinguishing tympanic membrane (TM) pathologies based on otoscopic images.MethodsAn otoscopic image database developed by utilizing publicly available online images and open databases was assessed by convolutional neural network (CNN) models including ResNet-50, Inception-V3, Inception-Resnet-V2, and MobileNetV2. Training and testing were conducted with a 75:25 breakdown. Area under the curve of receiver operating characteristics (AUC-ROC), accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were used to compare different CNN models' performances in classifying TM images.ResultsOur database included 400 images, organized into normal (n = 196) and abnormal classes (n = 204), including acute otitis media (n = 116), otitis externa (n = 44), chronic suppurative otitis media (n = 23), and cerumen impaction (n = 21). For binary classification between normal versus abnormal TM, the best performing model had average AUC-ROC of 0.902 (MobileNetV2), followed by 0.745 (Inception-Resnet-V2), 0.731 (ResNet-50), and 0.636 (Inception-V3). Accuracy ranged between 0.73-0.77, sensitivity 0.72-0.88, specificity 0.58-0.84, PPV 0.68-0.81, and NPV 0.73-0.83. Macro-AUC-ROC for MobileNetV2 based multiclass-classifier was 0.91, with accuracy of 66%. Binary and multiclass-classifier models based on MobileNetV2 were loaded onto a publicly accessible and user-friendly website (https://headneckml.com/tympanic). This allows the readership to upload TM images for real-time predictions using the developed algorithms.ConclusionsNovel CNN algorithms were developed with high AUC-ROCs for differentiating between various TM pathologies. This was further deployed as a proof-of-concept publicly accessible website for real-time predictions.

ObjectiveTo examine neurotologists' 2013 to 2016 Medicare Part-D data and evaluate commonly prescribed medications, longitudinal changes in prescribing patterns, presumed associated pathologies, and cost distribution across United States.MethodsComprehensive prescription data of Part-D-participating neurotologists was quiered from the 2013 to 2016 Medicare Part-D database. Outcome variables consisted of the 25 most commonly prescribed + refilled medications, cost distribution per medication, presumed associated pathologies, and standardized prescription cost across United States.ResultsOf the 594 available U.S. neurotologists, 336 (57%) were found in the Medicare Part-D database. In 2016, total prescription costs were $4 483 268 with an averaged $13 343 ± $18 698 per neurotologist. The three most frequently filled drugs were fluticasone propionate, ciprofloxacin, and triamterene-hydrochlorothiazide. From 2013 to 2016, the greatest change in prescription pattern was observed with azelastine (+188%), montelukast sodium (+104%), mupirocin (+63%), and mometasone (-91%), whereas the greatest change in relative drug cost distribution was seen in ofloxacin, (+695.7%) neomycin-polymyxin-hydrocortisone (+262.1%), and mometasone (-83%). Triamterene-hydrochlorothiazide, prednisone, montelukast, amoxicillin-clavulanate, azelastine, spironolactone, and mupirocin had statistically significant increases in average number of prescriptions per physician, whereas ofloxacin and mometasone had significant decreases. Medications presumably treating Eustachian tube dysfunction, Meniere's disease, and vestibular migraine had the greatest percent changes across years. Cost distribution of four drugs increased upwards of 100%. Geographic analysis demonstrated that Southern and Midwest regions had higher standardized prescription costs.ConclusionsThis study is the first to analyze neurotologists' trends in prescribing patterns, regional prescription cost distributions, and commonly treated pathologies. This can lead to better standardization of prescribing patterns and cost in the future.

BackgroundThis study evaluates the influence of facility case-volume on nasopharyngeal carcinoma (NPC) treatments and overall survival (OS).MethodsThe 2004-2015 National Cancer Database was queried for patients with NPC receiving definitive treatment.ResultsA total of 8260 patients (5-year OS: 63.4%) were included. The 1114 unique facilities were categorized into 854 low-volume (treating 1-8 patients), 200 intermediate-volume (treating 9-23 patients), and 60 high-volume (treating 24-187 patients) facilities. Kaplan-Meier log-rank analysis demonstrated significantly improved OS with high-volume facilities (p

The objective of this study is to evaluate the impact of preoperative frailty on short-term outcomes following intradural resection of skull base lesions. The 2005-2017 ACS-NSQIP database was queried for 30-day post-operative outcomes of patients undergoing intradural resection of the skull base, extracted by CPT codes 61601, 61606, 61608, and 61616. Five-item modified frailty index (mFI) was calculated based on the history of diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure, chronic hypertension, and functional status. A total of 701 patients (58.8% female, 72.0% white) were included with a mean age of 51.8 ± 14.7 years. Compared to patients with mFI = 0 (n = 403), patients with mFI ≥ 1 (n = 298) were more likely to have higher rates of reoperation (13.4% vs. 8.7%, p = 0.045), medical complications (20.5% vs. 9.2%, p

ObjectivesTo describe a cohort of patients presenting with long-term sudden sensorineural hearing loss (SSNHL) treated with prophylactic migraine and intratympanic steroid therapy.MethodsPatients presenting to a neurotology clinic at least 6 weeks from SSNHL onset were included. All patients received migraine prophylactic medication (nortriptyline, topiramate, and/or verapamil) and lifestyle changes for at least 6 weeks, as well as intratympanic steroid injections, if appropriate.ResultsTwenty-one patients (43% female) with a mean age of 64 ± 11 years who presented 9 ± 8 months (median = 5) from symptom onset were included. Posttreatment hearing thresholds were significantly improved compared with pretreatment thresholds at 500 Hz (49 ± 19 dB versus 55 ± 20 dB, p = 0.01), 1000 Hz (52 ± 19 dB versus 57 ± 21 dB, p = 0.03), low-frequency pure-tone average (53 ± 15 dB versus 57 ± 17 dB, p = 0.01), and speech-frequency pure-tone average (57 ± 13 dB versus 60 ± 15 dB, p = 0.02). Posttreatment word-recognition-score (WRS) and speech-recognition-threshold (SRT) were also significantly improved (45 ± 28% versus 70 ± 28% and 57 ± 18 dB versus 50 ± 16 dB, respectively, both p 50% WRS with an average improvement of 39 ± 9%.ConclusionsMigraine medications in addition to intratympanic steroid injections significantly improved SRT and hearing frequencies in 40% and 29% of SSNHL patients, respectively, while significant WRS recovery was observed in most (68%) patients. This suggests SSNHL may be an otologic migraine phenomenon, which may be at least partially reversible even after the traditional 30-day postonset window.

ObjectiveTo review overall survival (OS), recurrence patterns, and prognostic factors of de novo sinonasal squamous cell carcinoma (DN-SCC).Data sourcesPubMed, Scopus, OVID Medline, and Cochrane databases from 2006 to December 23, 2020.Review methodsThe study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.

Advanced T stage, presence of cervical nodal metastases, maxillary sinus primary site, and negative human papillomavirus (HPV) status were all correlated with significantly worse 5-year OS. Direct meta-analysis of 8 studies demonstrated patients with surgery were more likely to be alive at 5 years compared to those who did not receive surgery (odds ratio, 2.26; 95% CI, 1.48-3.47; P < .001). Recurrence was reported in 628 of 1471 patients from 26 studies (42.7%) with an aggregate 5-year locoregional control rate of 67.1% (range, 50.4%-93.3%).ConclusionThis systematic review and meta-analysis suggests that the 5-year OS rate for DN-SCC may approach 54.5% and recurrence rate approaches 42.7%. In addition, various tumor characteristics including advanced T stage, positive nodal status, maxillary sinus origin, and negative HPV status are all associated with decreased survival.

IntroductionThe short-term adverse events and predictors of morbidity in surgical resection of esthesioneuroblastoma (ENB) are largely unknown, and investigating these variables can help direct planning for at-risk patients.MethodsThe 2005-2017 National Surgical Quality Improvement Program database was queried to identify patients with a diagnosis of ENB undergoing skull base surgery for tumor resection. Information regarding demographics, patient morbidity score, pre-operative and intra-operative data, and post-operative outcomes were extracted. Cox proportional hazard analysis was utilized to assess complication and readmission/reoperation rates.ResultsA total of 95 patients undergoing skull base surgery for resection of ENB were included. Mean age, BMI, operation time, and post-operative length of stay (LOS) of the cohort were 53.6 ± 16.2 years, 29.1 ± 6.5, 392.0 ± 204.6 minutes, and 5.8 ± 4.6 days, respectively. In total, 31 patients (32.6%) experienced at least one 30-day adverse event, which included blood transfusion intra-operatively or within 72 hours from the operation (22.1%), readmission (10.7%), intubation >48 hours (7.4%), reintubation (4.2%), organ or space infection (4.2%), reoperation (4.0%), superficial or deep surgical site infection (2.1%), sepsis (2.1%), pulmonary embolism (1.1%), and myocardial infarction (1.1%). Patients who experienced at least one adverse event had significantly higher operation time (486.8 ± 230.4 vs. 347.5 ± 176.2 minutes, p = 0.002), LOS (9.2 ± 5.6 days vs. 4.2 ± 3.0, p

ObjectivesTo develop a smartphone application providing sound therapy and cognitive behavioral therapy (CBT) for treating tinnitus and performing a proof-of-concept pilot study evaluating its potential efficacy.MethodsAn interactive smartphone application available on iOS and Android platforms was developed, which provided an 8-week tinnitus-specific CBT and personalized and frequency-matched sound therapy. Included patients presented to our tertiary clinic between 2017 and 2018, while those waitlisted were regarded as controls. Three surveys were administrated: Tinnitus Handicap Inventory (THI), Generalized Anxiety Disorder 7-item (GAD-7), and Perceived Stress Scale (PSS).ResultsA total of 30 patients enrolled in this study consisting of 20 treatment and 10 control patients and mean age was 55.4 ± 11.6 years. Treatment and control patients had similar age, sex, and pre-enrolment GAD and PSS (all P > .05). Baseline THI scores were also similar between treatment and control cohorts (50.1 ± 21.9 vs 62.0 ± 20.7; P = .15). After 8 weeks, though changes in GAD and PSS scores were similar (P > .05), the treatment group reported a significantly greater improvement in THI scores (17.7 ± 15.8 vs 5.3 ± 10.5, P = .04).ConclusionsThis pilot study demonstrated potentially promising efficacy of a smartphone-based CBT and sound therapy platform for treating tinnitus and encourages future randomized controlled trials on this treatment modality.

IntroductionThe emergence of popular online rating websites, social media platforms, and public databases for industry payments and scholarly outputs provide a complete physician online presence which may guide choice and satisfaction.MethodsWebsites of all U.S. otolaryngology academic institutions were queried for fellowship-trained rhinologists. Additional well-known and academically active rhinologists were identified by the senior author. Online ratings and comments were collected from Google, Healthgrades, Vitals, and RateMD websites, and weighted rating scores (RS) were calculated on a 1-5 scale.ResultsA total of 210 rhinologists with 16 ± 9 years of practice were included, where 6901 online ratings (33 ± 47 per rhinologist) provided an average RS of 4.3 ± 0.6. RS was not different according to gender (p = 0.58), geographic quartile (p = 0.48), social media presence (p = 0.41), or attending top-ranked medical school (p = 0.86) or residency programs (p = 0.89). Years of practice negatively correlated with RS (R = -0.22, p$300 (n = 113). Attending a top-ranked medical school was associated with higher industry payments (p

ObjectivesTo investigate the clinical presentation, treatment breakdown, and overall survival (OS) outcomes of patients with neurofibromatosis type 2 (NF2)-associated bilateral vestibular schwannoma (NVS).MethodsThe 2004 to 2016 National Cancer Database was queried for patients with a diagnosis of VS. The "Laterality" code was used to stratify patients into sporadic unilateral vestibular schwannoma (UVS) and NVS.ResultsOf the 33,839 patients with VS, 155 (0.46%) were coded for NVS with an average age and tumor size of 37.4 ± 20.5 years and 23.5 ± 18.2 mm. Patients underwent observation (45.3%), surgery (29.3%), and radiotherapy (20.0%), and had a 5.8% 5-year mortality rate. Compared with UVS, NVS was negatively associated with receiving surgery (40.2% versus 29.3%, p = 0.02) while watchful observation was more prevalent (30.1% versus 45.3%, p = 0.001). In NVS, undergoing surgery was associated with larger tumor size (34.5 ± 21.2 versus 17.8 ± 13.3 mm, p = 0.001) and shorter diagnosis-to-treatment time (49.1 ± 60.6 versus 87.0 ± 78.5 d, p = 0.02), radiotherapy was associated with older age (44.4 ± 18.9 versus 35.2 ± 20.6 yr, p = 0.02) and longer diagnosis-to-treatment time (85.9 ± 77.9 versus 53.9 ± 65.5 d, p = 0.04), and observation was associated with smaller tumor size (17.8 ± 15.9 versus 28.0 ± 19.2 mm, p = 0.01). Kaplan-Meier log-rank analysis demonstrated similar 10-year OS between NVS and UVS patients (p = 0.58) without factoring the earlier age of presentation. Furthermore, there were no temporal changes in presentation/management of NVS, and OS was not dependent on the received treatment (p = 0.30).ConclusionsWith younger age, larger tumors, and more conservative management, NVS's OS was not treatment-dependent and was similar to sporadic UVS, though the latter should not be interpreted as similar life expectancies due to the much earlier presentation.

ObjectiveFor symptomatic nonsecreting pituitary adenomas (PAs), resection remains a critical option for treatment. In this study, the authors used a large-population national database to compare endoscopic surgery (ES) to nonendoscopic surgery (NES) for the surgical management of PA.MethodsThe National Cancer Database was queried for all patients diagnosed with histologically confirmed PA who underwent resection between 2010 and 2016 in which the surgical approach was specified. Due to database limitations, microsurgery and craniotomy were both categorized as NES.ResultsOf 30,488 identified patients, 16,373 (53.7%) underwent ES and 14,115 (46.3%) underwent NES. There was a significant increase in the use of ES over time (OR 1.16, p < 0.01). Furthermore, there was a significant temporal increase in ES approach for tumors ≥ 2 cm (OR 1.17, p < 0.01). Compared to NES, patients who underwent ES were younger (p = 0.01), were treated at academic centers (p < 0.01), lived a greater distance from their treatment site (p < 0.01), had smaller tumors (p < 0.01), had greater medical comorbidity burden (p = 0.04), had private insurance (p < 0.01), and had a higher household income (p < 0.01). After propensity score matching to control for age, tumor size, Charlson/Deyo score, and type of treatment center, patients who underwent ES had a shorter length of hospital stay (LOS) (3.9 ± 4.9 days vs 4.3 ± 5.4 days, p < 0.01), although rates of gross-total resection (GTR; p = 0.34), adjuvant radiotherapy (p = 0.41), and 90-day mortality (p = 0.45) were similar. On multivariate logistic regression, African American race (OR 0.85, p < 0.01) and tumor size ≥ 2 cm (OR 0.89, p = 0.01) were negative predictors of receiving ES, whereas diagnosis in more recent years (OR 1.16, p < 0.01), greater Charlson/Deyo score (OR 1.10, p = 0.01), receiving treatment at an academic institution (OR 1.67, p < 0.01) or at a treatment site ≥ 20 miles away (OR 1.17, p < 0.01), having private insurance (OR 1.09, p = 0.01), and having a higher household income (OR 1.11, p = 0.01) were predictive of receiving ES. Compared to the ES cohort, patients who started with ES and converted to NES (n = 293) had a higher ratio of nonwhite race (p < 0.01), uninsured insurance status (p < 0.01), longer LOS (p < 0.01), and higher rates of GTR (p = 0.04).ConclusionsThere is an increasing trend toward ES for PA resection including its use for larger tumors. Although ES may result in shorter LOS compared to NES, rates of GTR, need for adjuvant therapy, and short-term mortality may be similar. Factors such as tumor size, insurance status, facility type, income, race, and existing comorbidities may predict receiving ES.

ObjectivesTo identify migraine features present in a cohort of patients with recurrent benign paroxysmal positional vertigo (BPPV).MethodsPatients presenting with recurrent BPPV were surveyed. Recurrent BPPV was defined as three episodes or greater in 6 months before presentation, with resolution of symptoms after Epley maneuver. Current or past migraine headache (MH) diagnosis was made according to the International Headache Society guidelines.ResultsFifty-eight patients with recurrent BPPV with a mean age of 53.8 ± 17.4 years were included. Half (29 patients) fulfilled criteria for MH and half (29 patients) did not meet the criteria for MH (non-MH). No statistically significant difference was found in a majority of migraine-related symptoms between the MH and non-MH cohorts with recurrent BPPV. History of migraine medication usage (p = 0.008), presence of a weekly headache (p = 0.01), and duration of dizziness after positional vertigo (p = 0.01) were the only variables that were different on multivariate analysis between the MH and non-MH cohorts.ConclusionsHalf of recurrent BPPV patients suffer from migraine headaches. The other half presented with migraine-related symptoms, but do not meet criteria for MH. The high comorbidity of MH in our recurrent BPPV cohort as well as the absence of a statistically significant difference in a majority of migraine-related features among patients who did and did not fulfill criteria for MH may suggest that recurrent BPPV has a relationship with migraine. Recurrent BPPV may potentially be a manifestation of migraine in the inner ear, which we term otologic migraine including cochlear, vestibular, or cochleovestibular symptoms.

ObjectivesTo investigate how the decision to report United States Medical Licensing Examination (USMLE) Step 1 score as pass/fail will influence future otolaryngology residency application and match processes.Study designSurvey study.MethodsAn anonymous and voluntary survey approved by the Otolaryngology Program Directors Organization was administered to academic faculty members from April 24, 2020 through May 19, 2020.ResultsTwo hundred fifty-seven surveys were received from department chairs (17.5%), program directors (24.1%), associate program directors (12.5%), and department faculty (45.9%). USMLE Step 1 has been the most heavily weighted metric for offering interviews (44.0%), and it has correlated with residents' medical knowledge (77.0%) and in-service performance (79.8%) but not with surgical skills (57.6%) or patient care (47.1%). In total, 68.1% disagreed with the decision to make USMLE Step 1 pass/fail. This change is anticipated to lead to an increase in significance of USMLE Step 2 CK (89.1%), core clerkship grades (80.9%), elective rotation at the respective institutions (65.7%), Alpha Omega Alpha and other awards (64.6%), and letters of recommendation (63.8%). The new scoring is also anticipated to especially benefit students from top-ranked schools (70.8%), increase medical students' anxiety/uncertainty regarding obtaining interview invites (59.1%), and negatively affect international (51.4%), doctor of osteopathic medicine (45.9%), and underrepresented students (36.9%). Indication that USMLE Step 2 CK will significantly increase in weight varied according to department position (P = .049), geographic region (P = .047), years of practice (P

BackgroundThis study develops machine learning (ML) algorithms that use preoperative-only features to predict discharge-to-nonhome-facility (DNHF) and length-of-stay (LOS) following complex head and neck surgeries.MethodsPatients undergoing laryngectomy or composite tissue excision followed by free tissue transfer were extracted from the 2005 to 2017 NSQIP database.ResultsAmong the 2786 included patients, DNHF and mean LOS were 421 (15.1%) and 11.7 ± 8.8 days. Four classification models for predicting DNHF with high specificities (range, 0.80-0.84) were developed. The generalized linear and gradient boosting machine models performed best with receiver operating characteristic (ROC), accuracy, and negative predictive value (NPV) of 0.72-0.73, 0.75-0.76, and 0.88-0.89. Four regression models for predicting LOS in days were developed, where all performed similarly with mean absolute error and root mean-squared errors of 3.95-3.98 and 5.14-5.16. Both models were developed into an encrypted web-based interface: https://uci-ent.shinyapps.io/head-neck/.ConclusionNovel and proof-of-concept ML models to predict DNHF and LOS were developed and published as web-based interfaces.

Objectives/hypothesisTo examine the hearing outcomes of patients with sudden sensorineural hearing loss (SSNHL) treated with oral and intratympanic (IT) steroid only or a combination of steroid and migraine treatment. Our hypothesis was that adjuvant migraine medications may improve outcomes in SSNHL.MethodsA retrospective chart review at a tertiary otology center was conducted to identify patients with SSNHL who received oral steroid and IT dexamethasone injection(s) with or without migraine medications (a combination of nortriptyline and topiramate).ResultsA total of 47 patients received oral steroid and IT dexamethasone injection(s) only, and 46 patients received oral steroid and IT dexamethasone injection(s) as well as migraine lifestyle changes plus a combination of nortriptyline and topiramate. There were no significant differences in demographics and baseline audiometric data between the two groups. Both groups demonstrated improvements in pure tone average (PTA) and hearing thresholds at 250 Hz and 8000 Hz posttreatment. However, compared to steroid-only group, the adjuvant migraine medications group had significantly greater improvements in hearing thresholds at the lower frequencies (250 Hz, 500 Hz, 1000 Hz). Patients in the latter cohort also had greater improvement in PTA (P = .01) and received fewer IT injections (P = .04) PTA improvement of ≥ 10 dB was observed in 36 patients (78%) in the adjuvant migraine medications group and 22 patients (46%) in the control group (P < .001).ConclusionIn multimodal treatment of SSNHL, supplementing oral and IT steroid with migraine medications may result in greater improvements in lower frequency hearing thresholds and PTA. Furthermore, adjuvant migraine treatment can lead to decrease in number of IT injections, thus reducing procedure-related risks and complications.Level of evidence3 Laryngoscope, 131:E283-E288, 2021.

The current literature lacks strong guidelines regarding surgical management of patients with aspirin-exacerbated respiratory disease (AERD), who present with the clinical triad of chronic rhinosinusitis with nasal polyposis (CRSwNP), bronchial asthma, and aspirin/nonsteroidal anti-inflammatory drug intolerance. To further define the effectiveness of sinus surgery in treating AERD patients, this review article discusses current evidence regarding outcomes associated with more extensive surgery, the benefits of frontal sinus surgery on polyposis, and the role of Draf III intervention. Numerous studies suggest that Draf III frontal sinusotomy may be an efficacious early intervention due to increased neo-ostial patency and subsequent distribution of topical therapies. Future studies that further investigate the efficacy and safety of extensive surgery in AERD patients are warranted.

ObjectiveTo evaluate whether increased body mass index (BMI), age, or frailty influence vestibular schwannoma (VS) short-term surgical morbidity.MethodsThe 2005-2017 National Surgical Quality Improvement Program database was queried for patients with VS undergoing surgical resection. Age was stratified according to age

ObjectivesTo determine the relationship between vestibular migraine (VM) and motion sickness (MoS) susceptibility and their comorbidity in a large student population, and to assess whether experiencing MoS is associated with higher susceptibility for VM.MethodsSurveys including Motion Sickness Susceptibility Questionnaire (MSSQ) and questions assessing migraine-related symptoms as well as family history of motion sickness and migraine headache were distributed to the university undergraduate students through Facebook and email. Diagnosis of definite VM (dVM) was based on the criteria of the International Classification of Headache Disorders.ResultsOf 277 survey responders, 148 (53%) were found to be susceptible to MoS in which 74 (50%) met the criteria for dVM. Only childhood MSSQ score was significantly higher in participants with dVM compared with those without dVM (25.78 ± 15.89 versus 20.77 ± 14.28, p = 0.04); however, its significance faded out by regression analysis. Multivariate logistic regression showed having 1st degree relative with migraine headache (p = 0.02), neck stiffness (p = 0.001), and sinus pain, facial pressure, or headache with wind exposure (p = 0.02) to be independently associated with presence of dVM in MoS subjects.ConclusionsThough participants with MoS and dVM had significantly greater rates of migraine-related symptoms and family history of migraine headache compared with those with MoS only, childhood and adulthood MSSQ scores were similar. This and the high prevalence of dVM in our MoS cohort may suggest an existing association between MoS susceptibility and VM.

ObjectivesTo assess the validity of a bench-top model of an optical tympanometry device to diagnose in vitro model of middle ear effusion (MEE).Methods and materialsWe illuminated an in vitro model of ear canal and tympanic membrane with broadband light and relayed remitted light to a spectrometer system. We then used our proprietary algorithm to extract spectral features that, together with our logistic regression classifiers, led us to calculate a set of simplified indices related to different middle ear states. Our model included a glass vial covered with a porcine submucosa (representing the tympanic membrane) and filled with air, water, or milk solution (representing different MEE), and a set of cover-glass slips filled with either blood (representing erythema) or cerumen. By interchanging fluid types and cover-glass slips, we made measurements on combinations corresponding to normal healthy ear and purulent or serous MEE.ResultsEach simulated condition had a distinct spectral profile, which was then employed by our algorithm to discriminate clean and cerumen-covered purulent and serous MEE. Two logistic purulent and serous MEE classifiers correctly classified all in vitro middle ear states with 100% accuracy assessed by leave-one-out and k-fold cross validation.ConclusionsThis proof-of-concept in vitro study addressed an unmet need by introducing a device that easily and accurately can assess middle ear effusion. Future in vivo studies aimed at collecting data from clinical settings are warranted to further elucidate the validity of the technology in diagnosing pediatric acute otitis media.

ObjectivesTo evaluate the efficacy of a multi-modal migraine prophylaxis therapy for patients with hyperacusis.MethodsIn a prospective cohort, patients with hyperacusis were treated with a multi-modal step-wise migraine prophylactic regimen (nortriptyline, verapamil, topiramate, or a combination thereof) as well as lifestyle and dietary modifications. Pre- and post-treatment average loudness discomfort level (LDL), hyperacusis discomfort level measured by a visual analogue scale (VAS), and scores on the modified Khalfa questionnaire for severity of hyperacusis were compared.ResultsTwenty-two of the 25 patients (88%) reported subjective resolution of their symptoms following treatment. Post-treatment audiograms showed significant improvement in average LDL from 81.3 ± 3.2 dB to 86.4 ± 2.6 dB (P < .001), indicating increased sound tolerability. The VAS discomfort level also showed significant improvement from a pre-treatment average of 7.7 ± 1.1 to 3.7 ± 1.6 post-treatment (P < .001). There was also significant improvement in the average total score on modified Khalfa questionnaire (32.2 ± 3.6 vs 22.0 ± 5.7, P < .001).ConclusionsThe majority of patients with hyperacusis demonstrated symptomatic improvement from migraine prophylaxis therapy, as indicated by self-reported and audiometric measures. Our findings indicate that, for some patients, hyperacusis may share a pathophysiologic basis with migraine disorder and may be successfully managed with multimodal migraine prophylaxis therapy.

ObjectivesTo compare two statistical models, namely logistic regression and artificial neural network (ANN), in prediction of vestibular schwannoma (VS) recurrence.MethodsSeven hundred eighty-nine patients with VS diagnosis completed an online survey. Potential predictors for recurrence were derived from univariate analysis by reaching the cut off P value of .05. Those nine potential predictors were years since treatment, surgeon's specialty, resection amount, and having incomplete eye closure, dry eye, double vision, facial pain, seizure, and voice/swallowing problem as a complication following treatment. Multivariate binary logistic regression model was compared with a four-layer 9-5-10-1 feedforward backpropagation ANN for prediction of recurrence.ResultsThe overall recurrence rate was 14.5%. Significant predictors of recurrence in the regression model were years since treatment and resection amount (both P

BACKGROUND AND OBJECTIVES: Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease, causes recurrent mucous membrane hemorrhage, especially epistaxis. In this systematic review, we discuss the efficacies of the three most common laser photocoagulation treatments for HHT-related epistaxis. STUDY DESIGN/MATERIALS AND METHODS: A systematic literature search was conducted in PubMed and MEDLINE from database inception to March 2019. Studies reporting epistaxis outcomes following argon, neodymium-doped yttrium aluminum garnet (Nd:YAG), and diode laser photocoagulation for HHT were included. χ2 and Barnards exact tests were utilized to detect differences in reduced epistaxis frequency and intensity rates. RESULTS: Fifteen out of 157 published studies met our eligibility criteria, spanning a collective 362 patients. Argon, Nd:YAG, and diode laser therapy reduced epistaxis frequency in 90.4%, 88.9%, and 71.1% of patients, respectively, and reduced epistaxis intensity in 87.8%, 87.2%, and 71.1% of patients, respectively. Diode laser photocoagulation significantly underperformed in both outcome measurements when compared with argon (frequency: P = 0.005; intensity: P = 0.034) and Nd:YAG (frequency: P = 0.012; intensity: P = 0.041). There was no significant difference between argon and Nd:YAG in reducing HHT epistaxis frequency (P = 0.434) or intensity (P = 0.969). Categorizing HHT patients by clinical severity demonstrated a higher rate of improvement in the mild-moderate group compared with the severe group in both argon (P

ObjectivesTo evaluate if patients with a diagnosis of vestibular migraine (VM) by the International Classification of Headache Disorders (ICHD) criteria have meaningful differences in symptomatology and disease characteristics when compared to patients with concurrent vestibular symptoms and migraine that do not meet ICHD criteria.MethodsPatients who presented for the evaluation of vertigo were provided a detailed questionnaire about dizziness and migraine symptoms. Patients were assigned to either VM cohort (met ICHD criteria for VM) or migraine headache (MH) cohort (met ICHD criteria for migraine with or without aura but not VM). Disease characteristics, symptomatology, quality of life, and perceived stress score were compared between the cohorts.ResultsThe VM cohort demonstrated a shorter duration of vertigo episodes, 11 ± 22 hours versus 84 ± 146 hours in the MH cohort. In the VM cohort, 81% reported experiencing migraine headaches during episodes of vertigo, versus 61% in the MH cohort. All patients in the VM cohort reported a previous diagnosis of migraine headache, whereas 9% of the MH cohort had not been previously diagnosed by another physician. There was no difference in quality of life or perceived stress scores between the cohorts.ConclusionsA large proportion of vertigo patients with migrainous features do not meet the ICHD criteria for VM. The differences between cohorts represent selection bias rather than meaningful features unique to the cohorts. As such, VM and MH with vestibular symptoms may exist on a spectrum of the same disease process and may warrant the same treatment protocols.

Between 2016 and 2017, several U.S. Diplomats in Havana, Cuba, experienced perplexing vestibular and neurological symptoms attributed to an unknown source. They presented with significant vestibular and headache symptoms similar to individuals who experience vestibular migraine (VM). As such, we hypothesize that VM may be a possible explanation for the Havana cohort's presenting symptoms. To evaluate this hypothesis, we compared symptoms reported by the affected individuals in Havana, Cuba, to symptoms reported by corresponding patients from a tertiary academic neurotology clinic with a chief complaint of vertigo or disequilibrium, who met the International Classification of Headache Disorders criteria for VM. The prevalence of the Havana subjects experiencing various symptomatic domains was compared with the VM cohort, leading to 26 unique domains and statistical comparisons between the cohorts. Of the 26 domains compared between the two cohorts, 18 were not significantly different. This included the two most important components of meeting criteria for VM, namely the co-existence of headache and vestibular symptoms. On regression analysis, the only feature which kept its significant difference between the two cohorts was acute intense head pressure (P = 0.007). The domains with similar occurrence ratios included dizziness, headache, light sensitivity, hearing reduction, and tinnitus. In other words, multiple headache and vestibular symptoms, consistent with VM criteria, were similar between the two cohorts. The considerable similarities across various domains between VM patients and Havana subjects could be due to migraine as a possible common etiology for both groups. We propose VM as a potential etiology for the symptomatology in the U.S. diplomats in Cuba.
