The integration of MIP over inspiratory duration (ID) provides the sustained maximal inspiratory pressure (SMIP). Evidence on the reliability and validity of these measurements in COPD is not currently available. Therefore, we assessed the reliability, responsiveness and construct validity of the TIRE measures of inspiratory muscle performance in subjects with COPD. Patients and methods: Test–retest reliability, known-groups and convergent validity assessments were implemented simultaneously in 81 male subjects with mild to very severe COPD. TIRE measures were obtained using the portable PrO2 device, following standard guidelines. Results: All TIRE measures were found to be highly reliable, with SMIP demonstrating the strongest test–retest reliability with a nearly perfect intraclass correlation coefficient (ICC) of 0.99, while MIP and ID clustered closely together behind SMIP with ICC values of about 0.97. Our findings also demonstrated known-groups validity of all TIRE measures, with SMIP and ID yielding larger effect sizes when compared to MIP in distinguishing between subjects of different COPD status. Finally, our analyses confirmed convergent validity for both SMIP and ID, but not MIP. Conclusion: The TIRE measures of MIP, SMIP and ID have excellent test–retest reliability and demonstrated known-groups validity in subjects with COPD. SMIP and ID also demonstrated evidence of moderate convergent validity and appear to be more stable measures in this patient population than the traditional MIP.

Purpose: Retraction pocket and extrusion of the ossicular prosthesis remain significant problems after tympanoplasty in cholesteatoma surgery. This study presents an alternative surgical technique with a total compact ossicular prosthesis including cartilage, wire, and temporalis fascia. Materials and Methods: A total of 42 patients (27 adults, 15 children) underwent an ear operation for cholesteatoma requiring total ossicular chain replacement during a 10-year period. Surgery included canal wall down mastoidectomy and reconstruction of the middle ear in one stage. The total ossicular replacement prosthesis was made by a stainless steel wire passed and secured through a piece of conchal cartilage and temporalis fascia positioned on the free end of the wire. The analysis of our data included hearing results pre-surgery and post-surgery, complications recorded in the case notes, and postoperative otoscopic findings. Results: The mean air-bone gap decreased from 39.2 to 22.4 dB in the early postoperative period (mean follow-up, 12.8 months). Eight patients with a long-term follow-up (mean, 7.1 years) presented a small deterioration of their postoperative hearing improvement. The bone conduction did not present significant changes. Three patients developed postoperative infection and treated successfully with medical therapy. No significant complications as displacement or extrusion of the prosthesis and retraction pocket were detected postoperatively. Conclusion: This is an alternative tympanoplasty technique with a stable cartilage-wire-fascia total ossicular prosthesis. This technique has a low complication rate; good hearing results and offers another surgical option to the surgeon especially for cases where the cost is a concern. [ABSTRACT FROM AUTHOR]

Introduction: Laryngeal cancer, especially in the advanced stages, is a highly devastating disease, characterized by increased invasiveness and high rates of metastasis. Gelatinases A and B (MMP-2 and -9 respectively) are of particular interest due to their contribution to various stages of carcinogenesis. There is a growing body of evidence with regard to the prognostic value of certain MMPs and their possible role as tumour markers. Aim: To identify the pattern of alteration of serum gelatinases A and B in patients with laryngeal cancer following treatment, and a possible correlation with various clinicopathological parameters. Materials and methods: Forty nine patients were included in this study. Pre-treatment and post-treatment serum samples were collected and processed by gelatin zymography and western blotting. Results: Only the latent forms of MMP-2 and -9 were identified. Both gelatinases were increased in the serum of laryngeal cancer patients compared to healthy individuals. Patients with supraglottic tumours and active smokers had significantly higher pre-treatment levels of proMMP-2 than patients with glottic tumours (p < 0.05) and ex-smokers (p < 0.05), respectively. Patients with primary disease and patients with lymph node involvement showed lower serum proMMP-9 pre-treatment levels than patients with recurrence (p < 0.05) and patients without neck disease (p < 0.1), respectively. During the follow-up period the proMMP-2 serum levels increased significantly in the first ten to fifteen days after treatment, gradually decreasing over the following months. The proMMP-9 serum levels showed a gradual decrease after treatment, which was statistically significant (p<0.05). Conclusions: The post-treatment alteration pattern of proMMP-9 serum levels shows a possible role of this molecule as a tumour marker in laryngeal cancer. Further research is necessary to clarify the contribution of both gelatinases to the disease progress and determine their role as prognostic factors and tumour markers. [ABSTRACT FROM AUTHOR]

Chronic obstructive pulmonary disease (COPD) causes respiratory muscle weakness that leads to disabling dyspnea and poor functional performance. Therapies are often geared to improve inspiratory muscle performance. Yoga has been shown to improve exercise capacity, quality of life, and some pulmonary function measures in COPD, but little research has examined the effects of yoga training on inspiratory muscle performance. The purpose of this study was to investigate the effects of yoga training on inspiratory muscle performance in military veterans using the Test of Incremental Respiratory Endurance (TIRE). A prospective pilot study examined a 6-week yoga training program consisting of asana (poses) and pranayama (controlled breathing). Subjects had baseline inspiratory muscle weakness. The TIRE measured inspiratory muscle performance via the PrO2 device, providing maximal inspiratory pressure, sustained maximal inspiratory pressure, and inspiratory duration. Secondary measures included 6-minute walk distance, St. George Respiratory Questionnaire, Hospital Anxiety and Depression Scale, and spirometry. Mean age and BMI of subjects were 67 ± 3.6 years and 20.7 ± 3.3, respectively. The majority of subjects had severe (28.7%) or very severe (57.1%) COPD. Statistically significant improve m e n t s were seen in maximal inspiratory pressure (39.0 ± 14.1 cmH2O to 56.4 ± 20.6 cmH2O) and sustained maximal inspiratory pressure (244.1 ± 100.6 PTU to 308.1 ± 121.2 PTU). No statistically significant improvements we re observed in 6-minute walk distance, St. George Respiratory Questionnaire, Hospital Anxiety and Depression Scale, or spirometry. Yoga training has the potential in improve inspiratory muscle performance in veterans with severe to very severe COPD who present with inspiratory muscle weakness. This is of importance because improving inspira-tory muscle performance has been shown to improve COPD outcomes.

Chronic Obstructive Pulmonary Disease (COPD) is a chronic inflammatory airway disease punctuated by exacerbations (AECOPD). Subjects with frequent AECOPD, defined by having at least two exacerbations per year, experience accelerated loss of lung function, deterioration in quality of life and increase in mortality. Fibroblast growth factor (FGF)23, a hormone associated with systemic inflammation and altered metabolism is elevated in COPD. However, associations between FGF23 and AECOPD are unknown. In this cross-sectional study, individuals with COPD were enrolled between June 2016 and December 2016. Plasma samples were analyzed for intact FGF23 levels. Logistic regression analyses were used to measure associations between clinical variables, FGF23, and the frequent exacerbator phenotype. Our results showed that FGF23 levels were higher in frequent exacerbators as compared to patients without frequent exacerbations. FGF23 was also independently associated with frequent exacerbations (OR 1.02; 95%CI 1.004-1.04; p = 0.017), after adjusting for age, lung function, smoking, and oxygen use. In summary, FGF23 was associated with the frequent exacerbator phenotype and correlated with number of exacerbations recorded retrospectively and prospectively. Further studies are needed to explore the role of FGF 23 as a possible biomarker for AECOPD to better understand the pathobiology of COPD and to help develop therapeutic targets.

Background: Chronic obstructive pulmonary disease (COPD) is associated with an inflammatory response that becomes more pronounced in acute exacerbations. Considerable attention has recently focused on the value of several inflammatory mediators in predicting worsening of COPD-related symptoms. Whereas respiratory muscle dysfunction is also widely present in this population, little is known about how systemic inflammation relates to inspiratory muscle dysfunction in COPD., Methods: Fifty-three males with mild-to-very severe airflow obstruction underwent blood sampling for 23 inflammatory markers, including acute-phase proteins, cytokines and adipokines. Inspiratory muscle performance was assessed via the test of incremental respiratory endurance, providing measures of maximal (MIP) and sustained maximal (SMIP) inspiratory pressures., Results: The mean ± SD MIP and SMIP were 75.32 ± 19.62 cmH 2 O and 406.15 ± 124.55 PTU. MIP negatively correlated with CRP, SAA and cystatin C (r-values from -0.333 to -0.378, P < 0.02), while SMIP was inversely related to SAA and cystatin C (r = -0.534 and r = -0.396, P = 0.00). Significant differences in CRP, SAA, cystatin C and PARC were also found between subjects with and without inspiratory muscle weakness. No additional significant relationships were observed between either MIP or SMIP and other inflammatory markers in the study., Conclusions: MIP and SMIP are markedly reduced with greater degrees of inflammation in COPD as expressed by higher levels of CRP, SAA and cystatin C. Future research is needed to further examine the above findings and determine the impact of systemic inflammation along with its underlying mechanisms on inspiratory muscle function in COPD., (© 2019 John Wiley & Sons Ltd.)

Background: Inspiratory muscle function in COPD has been traditionally described in terms of maximal inspiratory pressure (MIP). Arguably, however, is the day-to-day relevance of MIP, given that individuals rarely need maximal inspiratory forces to perform general tasks, but rather repeated breathing muscle contractions which demand endurance. The sustained maximal inspiratory pressure (SMIP) reflects the ability of the respiratory muscles to maintain force over time (i.e. single-breath work capacity). We investigated the relationships between SMIP and COPD-related clinical outcomes, hypothesizing that SMIP would have superior correlational and discriminatory value when compared to MIP., Methods: 61 males with mild-to-very severe airflow obstruction underwent measures of spirometry, whole-body plethysmography, symptomatology, comorbidity, quality of life, exacerbations and mental health. MIP and SMIP were obtained via the Test of Incremental Respiratory Endurance., Results: The mean ± SD MIP and SMIP were 77.2 ± 22.9 cmH 2 O and 407.9 ± 122.8 PTU. Both MIP and SMIP positively correlated with pulmonary function, with SMIP displaying the highest correlations. We found significant differences in spirometry, hyperinflation, symptomatology, exacerbation frequency, comorbidity, quality of life and anxiety in subjects grouped as having reduced or normal single-breath work capacity. Finally, significantly lower SMIP values were found in individuals with an IC/TLC ratio ≤25%., Conclusions: The assessment of SMIP appears to have superior clinical value than MIP in COPD. Our analyses revealed that subjects whose SMIP was reduced experienced more severe airflow obstruction, greater hyperinflation, as well as worse health and mental status with increased symptomatology and impaired quality of life., (Copyright © 2019 Elsevier Ltd.

Objectives: The Test of Incremental Respiratory Endurance is a novel testing method that provides a unique examination of one's inspiratory muscle strength, work and endurance. Little is known about the relationship between inspiratory muscle performance and mortality risk in obstructive lung disease. We examined the relationship between the Test of Incremental Respiratory Endurance measures and the Body-mass index, airflow Obstruction, Dyspnea and Exercise index in chronic obstructive pulmonary disease., Methods: In all, 70 males with mild-to-very severe chronic obstructive pulmonary disease (mean ± standard deviation of 70.2 ± 5.9 years) underwent measurements of body-mass index, spirometry, dyspnea and a 6-min walk test from which the Body-mass index, airflow Obstruction, Dyspnea and Exercise score was calculated. The Test of Incremental Respiratory Endurance provided measures of maximal inspiratory pressure, sustained maximal inspiratory pressure and inspiratory duration., Results: All Test of Incremental Respiratory Endurance parameters inversely correlated with the Body-mass index, airflow Obstruction, Dyspnea and Exercise score: maximal inspiratory pressure (r = -0.355, p = 0.00), sustained maximal inspiratory pressure (r = -0.426, p = 0.00) and ID (r = -0.278, p = 0.02), with sustained maximal inspiratory pressure displaying the highest correlation. Independent significant correlations were also observed between the sustained maximal inspiratory pressure and all Body-mass index, airflow Obstruction, Dyspnea and Exercise score components, except for body-mass index. Finally, sustained maximal inspiratory pressure was significantly different among the Body-mass index, airflow Obstruction, Dyspnea and Exercise index quartiles., Discussion: The significant association between the Body-mass index, airflow Obstruction, Dyspnea and Exercise score and inspiratory muscle performance, in particular sustained maximal inspiratory pressure, suggests that these measures may have a potential prognostic value in the evaluation of chronic obstructive pulmonary disease., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Plain English Summary: The impacts of involvement in research are often described in terms of the difference made to the research, the people involved and less frequently the researchers. This paper focuses on the researchers' experiences of involvement, based on an evaluation of a pilot project supporting patient/carer involvement in research at Parkinson's UK. Telephone interviews were conducted with researchers from eight different research projects with involvement. The researchers reported gaining new knowledge from patients and carers. They used this knowledge to change their project designs, interventions and new devices. They also gained new skills in communicating with the public. Meeting patients for the first time had a profound impact on some researchers, causing a change in their professional values. Face-to-face contact seemed particularly important to gain a sense of the 'people behind the data', which suggests such meetings may result in impacts beyond those typically achieved through an exchange of documents. Involvement also influenced one researcher's choices and preferences, in terms of who to ask to take part in their study In summary, researchers often learn something new from talking to patients and carers. Facilitating this conversation seems important to maximise the impact of this learning. In future, it might be helpful for evaluations of involvement to ask researchers in more detail about what they learnt from patients/carers and how they applied their new skills and knowledge. This may help to understand how involvement can influence researchers' thinking to have an impact on research., Abstract: Background The impacts of patient/public involvement are often described in terms of the difference made to the research, the researchers and the people involved. Involvement often impacts on research by influencing the design, delivery and dissemination. Patients/the public report gaining new skills and knowledge, increased self-confidence, and satisfaction from making a difference. There are fewer reports of the impacts on researchers . This paper discusses the findings from an evaluation of a pilot project supporting patient/carer involvement in research at Parkinson's UK, focusing on the researchers' experiences. Methods Semi-structured telephone interviews were conducted with one researcher from each of the eight research projects which involved patients/carers in the pilot. The findings were analysed using theoretical thematic analysis. Results and discussion Learning can be described as acquiring new knowledge, behaviours, skills, values, or preferences. The researchers' reports reflected these different types of learning. They reported gaining new knowledge from patients and carers, which they recognised as distinct from their textbook knowledge of the condition. They used this learning to change their project designs and their new interventions and devices. They also gained new skills in communicating with patients and carers about the aims and significance of their research. Meeting patients for the first time had a profound impact on some researchers causing them to change their professional values. Face-to-face contact seemed particularly important to gain a sense of the 'people behind the data', which suggests such meetings may result in impacts beyond those typically achieved through an exchange of documents. The involvement also influenced one researchers' priorities and preferences, in terms of what questions to ask and of whom, in their project. Conclusions Researchers learn from an exchange of knowledge with patients/ carers, which influences their plans and actions. This seems to be one way that involvement subsequently has an impact on research. Facilitating this exchange seems important to support mutual learning and to enhance the impact on researchers. Future evaluations of involvement might benefit from exploring what researchers learnt from patients/carers and how they applied their new skills and knowledge.

Surgical resection of extracranial head and neck schwannomas (ECHNS) may be associated with major morbidity, but some ECHNSs can be safely treated expectantly. The aim of this study is to present a large case series and an algorithm for therapeutic decision-making in the management of ECHNS. The clinical records of patients diagnosed and treated for ECHNS between 1999 and 2012 at The Tel Aviv Sourasky Medical Center were reviewed retrospectively. All relevant demographic and medical data were extracted, among them presenting symptoms, surgical approaches, nerve of origin, complications and follow-up. A total of 53 patients with ECHNS were included in this clinical study. There were 29 males and 24 females whose mean age was 49.2 years, and all were treated surgically. The schwannomas originated from the brachial plexus, sympathetic chain, vagus nerve, trigeminal nerve, lip, hypoglossal nerve and larynx. Intracapsular enucleation was performed in 32 (60 %) patients, and the remaining 21 (40 %) patients underwent complete excision of the tumor with the involved nerve segment. Thirty-two patients (60 %) had postoperative neurological deficits. This study provides an algorithm to serve as a guideline in the decision-making process for this patient population. Although there is abundant evidence regarding the efficacy of radiotherapy for acoustic schwannoma, the value of radiotherapy as a treatment alternative for patients with ECNHS, especially those unsuitable for surgery, has not been established and further studies are warranted.

We evaluated the ototoxic effect of aminoglycosides on the outer hair cells of newborns in a neonatal intensive care unit (NICU) by means of distortion-product otoacoustic emissions (DPOAE) testing. Our study population was made up of 164 newborns who were divided into three groups: group A consisted of 105 infants who were given aminoglycoside therapy (either gentamicin or amikacin, or a combination of the two) as treatment for suspected or proven bacterial infection and septic states; group B included 30 newborns who were not given an antibiotic or who were given an antibiotic other than an aminoglycoside; group C, a control group, was made up of 29 healthy neonates who were hospitalized in the well-baby nursery. All the neonates underwent DPOAE testing in both ears (the f2 primary tone was presented at 2.0, 2.5, 3.2, and 4.0 kHz). We found that 41 patients in group A (39.0%) and 13 in group B (43.3%) failed the DPOAE test in one or both ears; the difference between these two groups was not statistically significant (p = 0.673). In group C, the DPOAE fail rate was 13.8% (4 newborns). In group A, there was no statistically significant association between the pass/fail rate and the specific aminoglycoside that was administered, or in the duration of antibiotic treatment, the number of doses, and the size of the mean daily dose and the mean total dose. In clinical practice, DPOAE testing is a sensitive method of evaluating the integrity of the outer hair cells in the basal turn of the cochlea after exposure to ototoxic drugs such as aminoglycosides. However, our study did not demonstrate that the aminoglycosides had any ototoxic effect on the hearing of neonates in the NICU.

Objective: To investigate the efficacy of hyperbaric oxygen therapy as a salvage treatment for patients with sudden sensorineural hearing loss (SSHL)., Materials and Methods: Fifteen patients affected by sudden hearing loss and treated with hyperbaric oxygen after steroid and vasodilator therapy failed constituted the study group. A control group of 30 patients who were treated with steroids and vasodilator alone was also included. Hyperbaric oxygen was administered once daily for 15 sessions at a constant pressure of 2.2 atmospheres. Pure-tone hearing thresholds were obtained for both groups before and after each treatment and frequency-specific thresholds 3 months after the end of hyperbaric oxygen therapy., Results: Salvage hyperbaric oxygen therapy was performed with a mean delay of 24 days from the onset of SSHL. The overall rate of hearing improvement was higher in the study group (7/15 cases, 46.6%) compared with the control group (4/30 cases, 13.3%). The mean pure-tone hearing average thresholds after salvage treatment in the study group was 53.4 dB HL (mean gain, 12.1 dB HL), which was significantly lower than that in the control group of 67.9 dB HL (mean gain, 2.7 dB HL). Hearing recovery was found to be better at low frequencies (250-500 Hz)., Conclusion: Hyperbaric oxygen therapy should be suggested to all patients for whom initial conventional medical treatment for SSHL has failed.

Objective: The aim of this study was to report the effect of unilateral cochlear implantation to vestibular system using vestibular evoked myogenic potentials (VEMPs) by air-conduction in a sample of children aged less than 5 years., Materials: This study consisted of 10 children (6 boys and 4 girls), who underwent cochlear implantation surgery at our clinic, and 8 normal hearing children (5 boys and 3 girls) matched for age. The VEMPs were performed before, 10 days, and 6 months after surgery. Both the implanted and unimplanted ears of each child were evaluated, with the cochlear implant both off and on., Results: Preoperatively, six (60%) children had abnormal VEMPs responses on both ears. In the postoperative sessions, no child showed any VEMPs response on the implanted side. The VEMPs were not recorded on the unimplanted side either, except for one case. At 6 months, the VEMPs response on the unimplanted side of three children became normal when the cochlear implant was on, and in two children with the device off., Conclusion: In the postoperative 6-month-period, the disappearance of VEMPs suggests that the saccule of children can be extensively damaged following cochlear implantation. A recovery of VEMPs can take place on the unimplanted side, with the cochlear implant both on and off. Despite this saccular injury, the absence of clinical signs in children could be explained by their ability to effectively compensate for such vestibular deficits., (Copyright © 2014 Elsevier Ireland Ltd.

Introduction. The nonsquamous carcinomas of the larynx are considered rare with the majority of malignant tumors in this area, reaching the rate of 95%, to be squamous cell neoplasms. Case Report. The case refers to a 53-year-old man that presented with symptomatology of motor nerve disease. During the evaluation of the neurologic disease, a subglottic mass of the larynx was revealed accidentally in the imaging examination. Under general anesthesia, we performed direct laryngoscopy and biopsy of the mass. The histopathologic examination revealed a hybrid carcinoma coexistence of two different carcinomas, an adenoid cystic carcinoma and an adenocarcinoma, not otherwise specified with poor differentiation. Regarding the therapeutic plan, the mass was considered inoperable due to its expansion to trachea and the patient received radiotherapy. Conclusions. Both the adenocarcinoma and adenoid cystic carcinoma are extremely rare types of malignant tumors in the larynx. The special interest of the present case is the coexistence of these two rare tumors in the same region of the larynx, being a hybrid tumor of the salivary glands in the larynx, which is the second reported case, based on our systematic literature review.

Laryngeal schwannomas (neurilemmomas) are extremely rare, and they present the otorhinolaryngologist with diagnostic and management challenges. These lesions usually present as a submucosal mass, and they are always a potential threat to the airway. We describe the case of a 75-year-old woman with a laryngeal schwannoma that arose from the left postcricoid area and covered the piriform sinus and arytenoid cartilage on that side. The tumor was completely excised under direct laryngoscopy with the use of a CO(2) laser, and preservation of the mucosal lining of the larynx was achieved.

Objectives: The aim of this study is to evaluate the effectiveness of a new manoeuvre in the treatment of posterior canal benign paroxysmal positional vertigo (p-BPPV) based on the idea that highly accelerated endolymphatic flow may lead a mass of otoconia to collide with the walls of the posterior semicircular canal, resulting in its disintegration and/or in the expulsion of the free particles from the posterior semicircular canal., Material-Methods: Our study group included 146 patients with a diagnosis of p-BPPV. All patients underwent the new manoeuvre, which consisted of several high-acceleration successive head movements in the horizontal plane performed by the same physician. The results of the study group were compared with those of a sham control group of 30 patients with p-BPPV undergoing placebo treatment. The patients of both groups were reviewed in a follow-up appointment 1 month and 1 year after the initial treatment., Results: Complete resolution of symptoms immediately after the manoeuvre was observed in 92% of patients. At 1-month and 1-year follow-up assessment, all the patients in the study group reported complete relief from their symptoms compared with only 13% and 43% of control patients respectively. Recurrence of symptoms was reported in 12 patients (8%) from the study group, who responded successfully to one additional session., Conclusions: This study establishes the efficacy of the new manoeuvre in the short- and long-term management of p-BPPV. It is a quick office procedure, usually resolving this disorder with a single session, although there some limitations in patients with underlying cervical spine pathology.

The most frequent addictions observed in the elderly are alcoholism and therapeutic drug abuse, due to the psychic and physical vulnerability associated with age. First, the impact of aging to addiction is presented from epidemiologic data. Somatic and neuropsychiatric complications, interaction between addiction and mental illnesses, and therapeutic approach are detailed. In the second part, the psychopathological basis likely to support the addictive conduit occurring in old age is explored.

We present the first reported case of simultaneously occurring bilateral antrochoanal polyps in a 49-year-old female patient, originated from previously performed inferior antrostomies as a treatment for chronic maxillary sinusitis. The antrochoanal polyps were removed by endoscopic surgery with combined approach through the inferior and middle meatal antrostomies. Microscopic analysis of the specimens showed benign inflammatory antrochoanal polyps. Follow-up appointment 6 months postoperatively showed patent antrostomies and no recurrence of the disease. Endoscopic treatment with middle meatal antrostomy is the recommended technique in most cases of antrochoanal polyps as the greater portion of the antral part of the polyp can be removed with the healthy antral mucosa left intact promoting epithelialization and mucociliary clearance of the antrum. Inferior antrostomy can be an additional part of the operation in selected cases.

Aim: Obstruction of the osteomeatal complex is the commonest anatomic finding in revision endoscopic sinus surgery. This study assesses the efficacy of topical mitomycin C in the middle meatus, intra- and postoperatively in the prevention of adhesion formation and restenosis of the maxillary sinus antrostomy., Materials and Methods: At the end of endoscopic surgery for chronic rhinosinusitis and four weeks postoperatively 30 patients received a pledget soaked with 1 ml of mitomycin C (0.5 mg/ml) in the middle meatus for 5 minutes while a pledget soaked in saline was placed in the contralateral side. Patients were assessed at least 6 months postoperatively by a blinded observer for the presence of synechiae and antrostomy stenosis. Medical records were reviewed for episodes of recurrent sinusitis., Results: Adhesions were observed in 8 patients. All adhesions rated as moderate to severe (4 patients) were observed in the control side (p = 0.043). Restenosis was observed in 2 sides treated with mitomycin C and in 9 control sides (p = 0.032). Recurrent symptoms of sinusitis occurred in three patients on the saline side., Conclusion: Mitomycin C is safe and effective in the prevention of severe adhesions and antrostomy stenosis when applied twice, during surgery and the early postoperative period.

Introduction: Warthin's tumour usually involves the parotid gland. However, it can also arise from ectopic salivary tissue in the para-parotid and latero-cervical lymph nodes., Case Report: We present the case of a 60-year-old man with a 3-month history of a smooth, mobile mass on the right side of the neck. Computed tomography (CT) scanning (coronal, axial and sagittal sections) showed a cystic lesion in the right upper neck without connection to the major salivary glands (8 x 4 x 3 cm). Complete surgical excision with a transverse neck incision was performed. Histological findings of the specimen revealed Warthin's tumour., Conclusion: This neoplasm should be included in the differential diagnosis of cystic lesions of the neck. Although rare, it has potential for malignant transformation. Coronal and sagittal CT scans are necessary to accurately localize the tumour and to differentiate the diagnosis from earring lesions of the parotid tail.

Objective: Hearing loss can significantly impair patient's quality of life, affecting communicative behavior, emotional and social function. This study assesses the impact of hearing aids on the quality of life of patients in a rural area and its correlation with socio-economic factors., Materials-Methods: Thirty patients (18 male, 12 female), with bilateral sensorineural hearing loss of variable etiology, using hearing aid for at least five years, were enrolled in this study. Mean age of subjects was 74 years. This study used the Glasgow Benefit Inventory (GBI) to quantify the changes in quality of life. Patients were divided in above and below criterion group. The criterion used was the median of the air contraction threshold improvement. The binaural use and the type of hearing aids were recorded and correlated with the type of social security service of patients., Results: Eighty per cent of patients reported significant benefit from the hearing aid use. The majority of patients (90%) used one hearing aid (mean GBI total score 35) and only 10% had binaural hearing aid (mean GBI total score 45). The majority of patients used analog hearing aid (56.5%) while 43.5% used digital hearing aid. Interestingly, it was found that patients did not attend appointments for hearing aids maintenance with a mean follow up of 2.5 years., Conclusion: This study demonstrates a trend of better quality of life for patients with bilateral hearing loss and binaural hearing aid use. The type of hearing aid is related to the funding from their social security service. Therefore more patients are using analog hearing aids, as they are less expensive than the digital hearing aids.

Problems/objectives: The aim of this study is to report on ossicular necrosis in the middle ear occurring shortly after head injury., Methodology: Our sample included 3 males and 2 females aged 9 to 37 years who complained of unilateral hearing loss after a head trauma that had occurred 3 to 6 months previously. The tympanic membranes were intact, and a CT-scan did not show fracture of the temporal bone. Audiometry showed a unilateral conductive hearing loss in all cases., Results: On tympanotomy exploration, 4 of the 5 patients had a necrosis of the lenticular process of the incus and one patient had a necrosis of the posterior and anterior crura of the stapes. Additionally, the incus was displaced at the incudomalleolar joint towards the promontory in two patients. The long process of the incus was surgically aligned and adjusted to the head of the stapes through interposition of either temporal fascia or a bone chip. At the 2-year-postoperative follow-up, the pure tone audiometry showed that the preoperative air-bone gap was almost closed with a mean of 11.8 dB., Conclusions: It is possible that the head injury resulted in ossicular displacement in the middle ear with disturbance of the local vascular supply. Due to the tenuous blood supply to the lenticular and long processes of the incus, this portion of the ossicular chain, including the stapes suprastructure, may become more vulnerable to an ischemic process and subsequent necrosis shortly after the head trauma.

The chondrosarcoma of the larynx is an exceptionally rare tumour. It appears mainly in white men in their 7th decade. The most significant clinical manifestation is hoarseness accompanied at times by stridor. It involves mainly the cricoid cartilage and the treatment of choice is surgical excision. A case of a large tumour of the cricoid cartilage is described. The diagnostic work-up consisted of two minor operations for biopsies and an MRI scan prior to the patient being treated with total laryngectomy.
