Otitis in Patients With Community-Acquired Bacterial Meningitis: A Nationwide Prospective Cohort Study.

BACKGROUND: Otitis is commonly associated with community-acquired bacterial meningitis, but the role of ear surgery as treatment is debated. In this study, we investigated the impact of otitis and ear surgery on outcome of adults with community-acquired bacterial meningitis. METHODS: We analyzed episodes of adults with community-acquired bacterial meningitis from a nationwide prospective cohort study in the Netherlands, between March 2006 and July 2021. RESULTS: A total of 2548 episodes of community-acquired bacterial meningitis were evaluated. Otitis was present in 696 episodes (27%). In these patients the primary causative pathogen was Streptococcus pneumoniae (615 of 696 [88%]), followed by Streptococcus pyogenes (5%) and Haemophilus influenzae (4%). In 519 of 632 otitis episodes (82%) an ear-nose-throat specialist was consulted, and surgery was performed in 287 of 519 (55%). The types of surgery performed were myringotomy with ventilation tube insertion in 110 of 287 episodes (38%), mastoidectomy in 103 of 287 (36%), and myringotomy alone in 74 of 287 (26%). Unfavorable outcome occurred in 210 of 696 episodes (30%) and in 65 of 696 episodes was fatal (9%). Otitis was associated with a favorable outcome in a multivariable analysis (odds ratio 0.74; 95% confidence interval [CI] .59-.92; P = .008). There was no association between outcome and ear surgery. CONCLUSIONS: Otitis is a common focus of infection in community-acquired bacterial meningitis in adults, with S. pneumoniae being the most common causative pathogen. Presence of otitis is associated with a favorable outcome. Ear surgery's impact on the outcome of otogenic meningitis patients remains uncertain.

Americans with disabilities act cases initiated by individuals with cochlear implants in the United States.

OBJECTIVE: The Americans with Disabilities Act (ADA) is a federal law that forbids discrimination against individuals with certain disabilities, including hearing impairment. This study aimed to determine the nature of ADA discrimination complaints in individuals with cochlear implants. METHODS: A search for court decisions containing the terms "cochlear implant" and ("Americans with Disabilities Act" or "ADA") from 1985 to 2021 was performed with the Westlaw Campus Research legal database. Cases were included and analyzed if at least one of the plaintiffs had a cochlear implant and was claiming discrimination related to their hearing impairment based on the ADA. RESULTS: 24 cases initiated between 2003 and 2021 in 19 US states were identified based on inclusion criteria. The highest number of cases occurred in California (N = 4, 16.7 %). The alleged discrimination most frequently took place at a K-12 school (N = 9, 37.5 %), workplace (N = 7, 29.2 %), or during an encounter with police/correctional officers (N = 4, 16.7 %). Fourteen (58.3 %) cases involved complaints under Title II (Public Services) of the ADA. Seven (29.2 %) involved Title I (Employment) and 4 (16.7 %) involved Title III (Public Accommodations). Summary judgment was given in favor of the defendant or the case was dismissed entirely in 16 (66.7 %) of the cases. CONCLUSION: Patients with cochlear implants are still at risk of discrimination because of their disability. Cochlear implantees, school employees, workplace supervisors, and law enforcement personnel can benefit from ADA education.

Havana syndrome: Overview for otolaryngologists.

Havana Syndrome is used to describe the array of deficits seen in diplomats stationed in Cuba from August 2016 to September 2017.1 Patients from this cohort were clinically studied, investigating their symptoms, audition and vestibular deficits, and imaging abnormalities seen on MRI.1-3 The primary studies were retrospective, looking at how these symptoms could be classified or fit into diagnostic criteria. The cohort had many similarities: a sound at the onset of symptoms, a mix of neurologic and otologic symptoms, and persistent symptoms that lasted for months.1-3 Theories of the cause of Havana Syndrome have led to no conclusive answer. Potential viral etiologies, mass psychogenic illness, and head trauma were examined as causes.1-5 Diseases with established diagnostic criteria were used to compare the patients' symptoms to try to find a disease that fits Havana Syndrome.3 Recent information from the Office of the Director of National Intelligence suggested the most likely cause to be mass psychogenic illness. With the cause of Havana Syndrome still unknown, a review of reported cases and reports helps otolaryngologists understand Havana Syndrome so they diagnose it only when appropriate and do not miss other conditions that may present with similar symptoms and that might respond well to targeted treatment.

Comparing the educational quality of YouTube and Facebook videos on tympanostomy tubes.

PURPOSE: Patients often refer to online materials when researching surgical procedures. This study compares the educational quality of online videos about tympanostomy tubes on two popular video platforms: YouTube and Facebook. This study provides clinicians with context about the content and quality of information patients may possess after watching online videos on tympanostomy tubes. MATERIALS AND METHODS: YouTube and Facebook were searched using key terms related to tympanostomy tubes. Videos were screened and scored in triplicate. DISCERN quality, content, production, and alternative medicine scores were assigned. Statistical analysis was conducted using GraphPad Prism. RESULTS: 76 YouTube and 86 Facebook videos were analyzed. DISCERN quality scores (mean = 1.8 vs. 1.4, P < .0001), content scores (mean = 1.7 vs. 1.0, P < .0001), and production scores (mean = 4.8 vs. 4.6, P = .0327) were significantly higher on YouTube compared to Facebook. 33 % of Facebook videos referenced alternative medicine, as compared with 0 % of YouTube videos (P < .0001). Physician/hospital-generated videos had significantly higher DISCERN and content scores than parent-, product-, and chiropractor-generated videos. Views did not correlate with DISCERN or content scores. CONCLUSION: YouTube is a better platform than Facebook for educational videos about tympanostomy tubes. YouTube videos had higher educational quality, more comprehensive content, and less alternative medicine. One third of Facebook videos advocated for alternative treatments. Importantly, videos on both platforms were of limited educational quality as demonstrated through low DISCERN reliability scores and coverage of few important content areas.

Evaluating the accuracy of a self-administered smartphone hearing test application in a geriatric population.

BACKGROUND: As the global population ages, hearing loss becomes increasingly prevalent, and is associated with neurocognitive and psychiatric comorbidities, impacting quality of life. Early screening and timely intervention might prevent or delay cognitive decline, a gap in care that can potentially be addressed by self-administered smartphone hearing tests. OBJECTIVE: This study aims to evaluate the accuracy of Mimi™ (Berlin, Germany), a commercially available self-administered smartphone hearing test compared to pure tone audiogram (PTA) in terms of both hearing levels and hearing thresholds in our local geriatric population > 65 years-old. METHOD: Fifty-two participants above 65 years of age requiring conventional audiograms were recruited from a National Referral University Hospital Otolaryngology clinic from March to June 2022. All participants were administered the conventional PTA tests in a sound-proof booth conducted by audiology technicians followed by Mimi™ Hearing Test in a quiet clinic room. Comparisons between the hearing levels of both tests were analyzed using Spearman's rank correlation coefficient, Bland-Altman plots and Gwet's Kappa which looked at concordance. Hearing thresholds were then analysed using the Wilcoxon signed rank (SR) test. RESULTS: Mimi™ showed strong to very strong correlation with good agreement compared to readings obtained from formal PTA. Concordance in determining hearing loss also showed substantial to almost perfect agreement at each individual frequency, with values of kappa falling between 0.735-0.857. In terms of thresholds, there were no significant differences in thresholds given by both tests except for 2.0 kHz, HFPTA and 4FPTA (p < 0.05). CONCLUSION: Mimi™ serves as a good screening tool for detection of moderate hearing loss for early pickup and treatment except at higher frequencies. The smartphone hearing test is also less accurate in determining the extent of hearing loss and formal PTA after hearing loss is detected on screening should still be standard of care.

The influence of intraoperative auditory brainstem responses on vibroplasty coupling-quality and analysis of the impact of different fixation steps on the coupling.

PURPOSE: The Vibrant Soundbridge (VSB) is an established active-middle-ear-implant for patients with moderate-to-profound hearing-loss. This surgery is referred to as "Vibroplasty". Sufficient transfer of the VSB's floating-mass-transducers (FMT) energy to the inner ear is a crucial factor influencing the coupling-quality (CQ). However, assessing CQ is hamper by two issues: the method of CQ-assessment itself and the method of FMT-fixation during Vibroplasty. METHODS: This prospective study explored the influence of intraoperative auditory-brainstem-response (+ ABR) measurements and various fixation methods on postoperative CQ after Vibroplasty as compared to matched-patients after Vibroplasty without intraoperative ABR (-ABR). Propensity-score-matching was performed based on preoperative bone-conduction-pure-tone-average-3 (BC-PTA3) at 1-, 2- and 4 kHz. Primary outcome parameters were postoperative CQ-PTA3, intraoperative ABR threshold for various fixation methods and postoperative BC-PTA3. RESULTS: A total of 28 patients were included, of which 14 were + ABR. Preoperative BC-PTA3, sex, age, and number of previous surgeries did not differ significantly between groups (all p > 0.301). Mean postoperative CQ-PTA3 was significantly better for + ABR (1.8 vs. 12.3 dB-HL; p = 0.006). Mean intraoperative ABR threshold was superior for cartilage-counter-bearing and cartilage-housing compared to additional fixation with injectable-platelet-rich- fibrin (53 vs. 56 & 57 dB-HL, respectively; p = 0.04; η2 = 0.33). Mean postoperative BC-PTA3 did not significantly differ between patients (41.4 vs. 41.8 dB-HL; p = 0.77). A total of 7% of the patients required intraoperative readjustment of the FMT based on unsatisfactory intraoperative ABR threshold. CONCLUSION: Intraoperative ABR measurement resulted in significantly better postoperative CQ. Cartilage-counter-bearing and cartilage-housing were observed to have superior CQ. A total of 7% of the patients could be spared revision-Vibroplasty due to intraoperative ABR measurement.

The effect of piston diameter in primary stapes surgery on surgical success.

PURPOSE: To evaluate the effect of piston diameter in patients undergoing primary stapes surgery on audiometric results and postoperative complications. METHODS: A retrospective single-center cohort study was performed. Adult patients who underwent primary stapes surgery between January 2013 and April 2022 and received a 0.4-mm-diameter piston or a 0.6-mm-diameter piston were included. The primary and secondary outcomes were pre- and postoperative pure-tone audiometry, pre- and postoperative speech audiometry, postoperative complications, intraoperative anatomical difficulties, and the need for revision stapes surgery. The pure-tone audiometry included air conduction, bone conduction, and air-bone gap averaged over 0.5, 1, 2 and 3 kHz. RESULTS: In total, 280 otosclerosis patients who underwent 321 primary stapes surgeries were included. The audiometric outcomes were significantly better in the 0.6 mm group compared to the 0.4 mm group in terms of gain in air conduction (median = 24 and 20 dB, respectively), postoperative air-bone gap (median = 7.5 and 9.4 dB, respectively), gain in air-bone gap (median = 20.0 and 18.1 dB, respectively), air-bone gap closure to 10 dB or less (75% and 59%, respectively) and 100% speech reception (median = 75 and 80 dB, respectively). We found no statistically significant difference in postoperative dizziness, postoperative complications and the need for revision stapes surgery between the 0.4 and 0.6 mm group. The incidence of anatomical difficulties was higher in the 0.4 mm group. CONCLUSION: The use of a 0.6-mm-diameter piston during stapes surgery seems to provide better audiometric results compared to a 0.4-mm-diameter piston, and should be the preferred piston size in otosclerosis surgery. We found no statistically significant difference in postoperative complications between the 0.4- and 0.6-mm-diameter piston. Based on the results, we recommend always using a 0.6-mm-diameter piston during primary stapes surgery unless anatomical difficulties do not allow it.

Follow-up strategies in pediatric cholesteatoma: a systematic review.

PURPOSE: The aim of this article was to systematically review the literature on the pediatric population surgically treated for cholesteatoma and describe the applied post-operative follow-up strategies. METHODS: A systematic review was conducted following the Primary Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement recommendations. After running the selected search string in PubMed, Scopus and Google Scholar, studies in English, reporting on surgically treated pediatric cholesteatoma patients (age younger or equal to 18 year-old) were retrieved. Both primary and revision cholesteatoma surgeries were included. Articles lacking specific data on post-surgical follow-up and case series with less than 10 patients were excluded. RESULTS: Nineteen papers, published between 2000 and 2023, were included for final analysis. Fourteen studies were retrospective and five prospective, for a total of 1319 patients and 1349 operated ears. Male to female ratio was 1.8:1, with a mean age at surgery of 10.4 years (range 1-18). The mean length of the follow-up after surgery was 4.4 ± 1.7 years (range 1-6.9). Clinical follow-up was detailed in 9 studies (47%) with otomicroscopy being the most common evaluation. In most articles (n = 8, 50%), MRI alone was utilized for radiological follow-up, while in 3 studies (19%), CT scans were employed exclusively. In 5 studies (31%), MRI was combined with CT scans. The timing of radiological investigations varied widely (ranging from 6 months to 3 years). A second-look strategy was reported in 14 studies (74%). CONCLUSION: This systematic review highlights the heterogeneity of the follow-up strategies applied to pediatric patients after cholesteatoma surgery, both in terms of timing and types of investigations.

A study on the efficacy of combined surgery in advanced-stage congenital cholesteatoma with canal-wall-up surgery.

PURPOSE: This study aimed to compare the outcomes of patients with advanced congenital cholesteatoma who underwent microscopic or endoscope-combined Canal Wall Up Tympanomastoidectomy (CWUT) in our clinic and to determine the contribution of endoscope use in reducing recurrence/residual rates. METHODS: In this retrospective study, the data of individuals who underwent microscopic or combined endoscopic surgery between 2008 and 2022 in our clinic were scanned from the database. Demographic data, preoperative computed tomography (CT) findings, preoperative and postoperative hearing results, operation and intraoperative status of the ossicles, duration of surgery, postoperative follow-up period, recurrence and residual disease status during follow-up were investigated. RESULTS: The data of 37 pediatric cases operated in our clinic were included in the study. All of the included cases were Potsic Stage 4 patients who underwent CWUT. The mean age of the operated individuals was 8.7 years (5-12 years) and the mean follow-up period was 47.3 months (12-112 months). 19 cases were performed microscopically only, 2 recurrences and 5 residuals were detected. 18 cases were performed combined and 1 recurrence and 1 residual was found. CONCLUSION: In this study, it was determined that using an endoscope together with a microscope in congenital cholesteatoma cases, decreased the rate of recurrence and residual disease by protecting the external auditory canal in patients with advanced mastoid invasion.

Long-term facial nerve outcome in surgically treated petrous bone cholesteatoma patients.

INTRODUCTION: The term petrous bone cholesteatoma (PBC) represents a slow-growing epidermal lesion arising from the petrous part of the temporal bone. It is a rare incidence accounting for only 4-9% of all petrous bone lesions. PBC represents a real surgical challenge due to its complex relationship with critical neurovascular structures. OBJECTIVE: To demonstrate our experience in using various options of facial nerve (FN) management during surgical treatment of PBC and analyze the long-term facial function outcomes. STUDY DESIGN: Retrospective medical record review in a quaternary skull-base center. MATERIALS AND METHODS: Medical records of 298 PBC cases operated between the years 1983 and 2024 were thoroughly evaluated. Sanna's classification scheme was used to classify cases into the appropriate class and the House-Brackmann (HB) grading system of the FN was used to assess the facial function pre- and postoperatively. RESULTS: A total of 298 PBC cases were surgically treated at our center. Males constitute 68% (n = 203) of total operated PBC patients while the rest 32% (95) were females, making the male-to-female ratio 2.2:1. The age in this series ranged from 9 to 85. According to updated Sanna's PBC classification, 44% were supralabyrinthine, 33% were massive, 9% were infralabyrinthine-apical, 8% were infralabyrinthine, and 5% were apical. On preoperative FN function examination, 45% (n = 133) of patients had various degrees of paresis and complete paralysis whereas 55% (n = 165) had normal FN function. The commonest degree of paresis observed was HB-III (18.5%) followed by HB-IV (5.7%). A total of 40(13.4%) patients, however, had complete facial paralysis at the initial presentation. The facial function was compromised more frequently in supralabyrinthine and massive PBCs. Among the total patients who had an abnormal facial function at presentation, 52% had paresis/paralysis for less than a year whereas 48% had FN paresis/paralysis for greater than one year. The most commonly used surgical approaches at our center were transotic (TO), modified transcochlear type A (MTCA) with rerouting of the FN, and translabyrinthine (TLAB) with external auditory canal (EAC) closure. Intraoperatively an intact fallopian canal was found only in 33% (n = 99) cases whereas the rest 67% (n = 199) had erosion of the fallopian canal either with intact (n = 24) or infiltrated FN (n = 175). The FN was maintained in the bony fallopian canal in 35% (n = 104) cases. An active form of FN management, however, was required in 65% (n = 194) of cases either intraoperatively or as a second-stage procedure. Factors affecting postoperative FN function include age, preoperative FN function (HB), duration of paralysis, class of PBC, surgical approach, and method of active FN management. CONCLUSION: PBCs represent diagnostically and surgically challenging lesions of temporal bone which are usually frustrating to the treating surgeon. Preoperative anatomic classification of the lesion enables the physician to choose the appropriate surgical approach. Sanna's classification is the most widely accepted system used to classify PBC. This classification is based on the relation of the lesion to the labyrinthine block. Active FN management, including rerouting, end-to-end anastomosis, cable nerve grafting, and masseteric-to-FN anastomosis routinely come into play in the surgical management of PBCs, and the postoperative FN results after such interventions can be satisfactory in most cases.

Dizziness in adults with chronic otitis media at two otology referral centres in Colombia: a cross-sectional study in a middle-income country.

OBJECTIVE: This study aimed to determine the prevalence of dizziness and its associated factors in patients with COM at two otologic referral centres in a middle-income country. DESIGN: Cross-sectional study. Adults with and without COM diagnosis from two otology-referral centres in Bogotá (Colombia) were included. Dizziness and quality of life were assessed using the "Chronic Suppurative Otitis Media Questionnaire-12" (COMQ-12), and sociodemographic questionnaires were applied. Otoscopic evaluation and audiometric data were collected. STUDY SAMPLE: A total of 231 adults. RESULTS: Of the 231 participants, up to 64.5% (n = 149) reported at least mild inconvenience due to dizziness. Factors associated with dizziness included female sex (aPR: 1.23; 95% CI: 1.04-1.46), chronic suppurative otitis media (aPR: 3.02; 95% CI: 1.21-7.52), and severe tinnitus (aPR: 1.75; 95% CI: 1.24-2.48). An interaction was found between socioeconomic status and educational level, with more frequent reports of dizziness in the middle/high economic status and secondary education (aPR: 3.09; 95% CI: 0.52-18.55; p < 0.001). Differences of 14 points in symptom severity and 18.5 points in the total score of the COMQ-12 were found between the groups with dizziness and without dizziness. CONCLUSIONS: Dizziness was frequent in patients with COM and was associated with severe tinnitus and quality of life deterioration.

A New Community-to-Hospital Specialist Otology Pathway Using Telemedicine: A Pilot Study of 50 Patients.

INTRODUCTION: Pathway innovation using smartphone otoscopy and tablet-based audiometry technologies to deliver ear and hearing services via trained audiologists may improve efficiency of the service. An ENT-integrated-community-ear service (ENTICES-combining community audiology management, remote ENT review and novel technologies) was piloted. We aimed to assess the efficiency and safety of ENTICES. METHOD: ENTICES was a community-based and audiologist-led pathway. Patients with otological symptoms were self-referred to this service. Smartphone otoscopy and tablet-based audiograms were performed. Two otologists reviewed all decisions made in the community by audiologists based on video-otoscopy, hearing tests and chart reviews. Data on the first 50 consecutive new patients attending either consultant-led hospital otology clinics (HOC), audiologist-led hospital advanced audiology diagnostics (AAD) or ENTICES clinics were collected between 1 August 2021 and 31 December 2021. Data were collected through chart reviews and questionnaires to compare the three pathways with respect to efficiency, patient satisfaction, technology utility and safety. RESULTS: No audiology-led ENTICES decisions were amended by hospital otologists following remote review. Remote review of video-otoscopy with history was sufficient for a diagnosis in 80% of cases. Adding hearing tests and standardised history increased the diagnostic yield to 98%. Patient satisfaction scores showed 100% service recommendation. The cost per patient, per visit, was £83.36, £99.07 and £69.72 for AAD, HOC or ENTICES, respectively. CONCLUSION: ENTICES provides a safe ear and hearing service that patients rated highly. Thirty-two per cent of hospital otology patients were eligible for this service. For those patients, ENTICES is 20% more cost-effective and can reduce the number of clinic visits by up to 60% compared with HOC.

Quality assessment of patient-reported outcome measures for patients with multiple ear complaints.

INTRODUCTION: There is an increased demand for well-validated PROMs in otology. This study will systematically assess the methodological quality of all published patient-reported outcome measures (PROMS) for patients with multiple ear complaints and to identify the best suitable PROM for use by clinicians treating patients with multiple ear complaints. METHODS: An extensive systematic mapping review of all otology questionnaires was performed to identify questionnaires measuring multiple ear complaints. The 'Consensus-based standards for the selection of health measurement Instruments' (COSMIN) checklists were used to evaluate the quality of the questionnaire by two researchers. The worst item score per aspect of the methodological assessment counted. RESULTS: Twelve multiple-complaint questionnaires were included in the study for quality assessment. Ten questionnaires were disease-specific (COMQ-12, CES, ZCMEI-21, MD-POSI, PAN-QOL, ETDQ-7, MDOQ, GYSSCDQ, COMOT-15 and DEU-MDDS). Two questionnaires were ear domain-specific (OQUA and COQOL). The majority of multiple complaint questionnaires lacked good design with concept elicitation and patient involvement. CONCLUSION: For the majority of questionnaires, the quality assessment was inadequate as only a few authors consulted with patients affected by the complaints in the development. Modifications of earlier versions of PROMS or combinations of multiple questionnaires lead to ongoing (cross-cultural) validation of these questionnaires albeit mediocre design and validation. The two domain-specific questionnaires are the COQOL and OQUA, both with adequate quality but different focus. COQOL to quantify the quality of life and OQUA to measure and evaluate the severity and impact of ear complaints. [Correction added on 26 January 2024, after first online publication: In the preceding sentence, the spelling of the abbreviation COQOL has been corrected in this version.].

Risk factors associated with the development of chronic suppurative otitis media in children: Systematic review and meta-analysis.

OBJECTIVES: Chronic suppurative otitis media (CSOM) is defined as persistent discharge through a tympanic membrane perforation for greater than 2 weeks. It is associated with a significant disease burden, including hearing loss, and reducing its incidence could significantly improve short- and long-term health. We aimed to identify risk factors associated with the development of CSOM in children. DESIGN AND SETTING: Systematic review and meta-analysis of studies set in community, primary and secondary care settings, identified from Medline, Embase and Cochrane databases from 2000 to 2022. PARTICIPANTS: Children 16 years old and below. MAIN OUTCOME MEASURES: Clinical diagnosis of CSOM. RESULTS: In total, 739 papers were screened, with 12 deemed eligible for inclusion in the systematic review, of which, 10 were included in the meta-analysis. Risk factors examined included perinatal, patient, dietary, environmental and parental factors. Meta-analysis results indicate that atopy (RR = 1.18, 95% CI [1.01-1.37], p = .04, 2 studies); and birth weight <2500 g (RR = 1.79 [1.27-2.50], p < .01, 2 studies) are associated with an increased risk of CSOM development. Factors not associated were male sex (RR = 0.96 [0.82-1.13], p = .62, 8 studies); exposure to passive smoking (RR = 1.27 [0.81-2.01], p = .30, 3 studies); and parental history of otitis media (RR = 1.14 [0.59-2.20], p = .69, 2 studies). CONCLUSION: Optimal management of risk factors associated with CSOM development will help reduce the burden of disease and prevent disease progression or recurrence. The current quality of evidence in the literature is variable and heterogeneous. Future studies should aim to use standardised classification systems to define risk factors to allow meta-analysis.

[An unusual case: fracture of the handle of the malleus due to finger manipulation]. / Ein ungewöhnlicher Fall: Fraktur des Hammergriffs durch Fingermanipulation.

An isolated fracture of the handle of the malleus is a rare entity in otorhinolaryngology and manifests clinically as acute-onset unilateral hearing loss. Several factors may cause this injury, including acute barotraumatic pressure changes or traumatic events. Various therapeutic approaches such as tympanoplasty, autologous graft, or application of bone cement are discussed. We report the case of a 46-year-old female patient who developed acute hearing loss in her left ear after finger manipulation. Clinical evaluation revealed axial displacement of the handle of the malleus and audiometry indicated conductive hearing loss. After otoscopy, audiometry, and computed tomography, tympanoscopy was indicated due to suspicion of ossicular chain disruption. Intraoperatively, an isolated fracture of the handle of malleus was found, which was treated with glass ionomer cement. Following postoperative examination, there was progressive improvement in the acoustic transmission component, such that a normal hearing threshold was observed 4 months postoperatively. This case report underlines the importance of precise diagnosis and individualized treatment for rare middle ear injuries.

Psychometric properties of the Turkish version of the Vestibular Migraine Patient Assessment Tool and Handicap Inventory.

Background/aim: There are insufficient tools to assist in the diagnosis and treatment of vestibular migraine. Hence, the aim of this study was to perform the Turkish adaptation of the Vestibular Migraine Patient Assessment Tool and Handicap Inventory (VM-PATHI). Materials and methods: After the language and content validity was completed, a pilot study was conducted. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to test construct validity, and as a result of the validity analyses, Cronbach's alpha internal consistency coefficient and test-retest analyses were conducted for reliability. Results: In the study, in which 289 participants were evaluated, the Kaiser-Meyer-Olkin coefficient was calculated as 0.903. The percentage of variance explained by the EFA was 67.246% and the range of factor load change was 0.433-0.828. The scale structure was tested with CFA and the model was confirmed with adequate goodness of fit index values. The Cronbach's alpha internal consistency coefficient of the scale was 0.931. Conclusion: The VM-PATHI is a valid and reliable tool for the subjective evaluation of vestibular migraine in Türkiye.

COX inhibitor use during definitive radiotherapy is associated with worse hearing preservation in patients with vestibular schwannoma.

PURPOSE: Patients with vestibular schwannoma undergoing definitive radiotherapy commonly experience hearing loss due to tumor and treatment effects; however, there is limited data evaluating concurrent medication use and other clinicopathologic factors associated with hearing preservation during and after radiotherapy. We performed a retrospective cohort study reviewing consecutive patients from 2004 to 2019 treated with radiotherapy for vestibular schwannoma at our institution. METHODS: Ninety four patients with concurrent medications, baseline audiograms, and post-radiotherapy audiograms available were evaluable. We performed chi-squared analyses of the frequency of various clinicopathologic factors and t-tests evaluating the degree of hearing loss based on audiograms. RESULTS: At a median follow-up of 35.7 months (mean: 46.5 months), the baseline pure-tone average (PTA) of the ipsilateral ear worsened from 38.4 to 59.5 dB following completion of radiotherapy (difference: 21.1, 95% CI 17.8-24.4 dB, p < 0.001). 36 patients (38.3%) reported regular use of cyclooxygenase (COX) inhibitors (including acetaminophen and NSAIDs) during radiotherapy. The mean increase in PTA was significantly higher for patients taking COX inhibitors (25.8 dB vs 18.1 dB, p = 0.024) in the ipsilateral ear but not for the contralateral side. COX inhibitor use remained independently associated with worse PTA in the multivariate analysis. CONCLUSION: COX inhibitor use during definitive radiotherapy is associated with worse hearing loss in the affected ear but not for the contralateral side. This suggests the ototoxic effects of COX inhibitors may influence the effects of radiotherapy. These results could have clinical implications and warrant further investigation.

Clinically relevant increases in serum neurofilament light chain and glial fibrillary acidic protein in patients with Susac syndrome.

BACKGROUND AND PURPOSE: Serum levels of neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) are promising neuro-axonal damage and astrocytic activation biomarkers. Susac syndrome (SS) is an increasingly recognized neurological condition and biomarkers that can help assess and monitor disease evolution are highly needed for the adequate management of these patients. sNfL and sGFAP levels were evaluated in patients with SS and their clinical relevance in the relapse and remission phase of the disease was assessed. METHODS: As part of a multicentre study that enrolled patients diagnosed with SS from six international centres, sNfL and sGFAP levels were assessed in 22 SS patients (nine during a relapse and 13 in remission) and 59 age- and sex-matched healthy controls using SimoaTM assay Neurology 2-Plex B Kit. RESULTS: Serum NfL levels were higher than those of healthy controls (p < 0.001) in SS patients and in both subgroups of patients in relapse and in remission (p < 0.001 for both), with significantly higher levels in relapse than in remission (p = 0.008). sNfL levels showed a negative correlation with time from the last relapse (r = -0.663; p = 0.001). sGFAP levels were slightly higher in the whole group of patients than in healthy controls (p = 0.046) and were more pronounced in relapse than in remission (p = 0.013). CONCLUSION: In SS patients, both sNFL and sGFAP levels increased compared with healthy controls. Both biomarkers had higher levels during clinical relapse and much lower levels in remission. sNFL was shown to be time sensitive to clinical changes and can be useful to monitor neuro-axonal damage in SS.

Solitary fibrous tumor of the tympanic membrane a case report and systematic review.

PURPOSE: Otological solitary fibrous tumors (SFT) are exceedingly rare. There has been no report of SFT localized to the tympanic membrane. To report on a rare case of solitary fibrous tumor of the tympanic membrane and provide systematic review of the literature pertaining the demographics and pathophysiology of otological SFTs. MATERIALS AND METHODS: This review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. A search of PubMed, Google Scholar, and Cochrane Library databases was conducted to identify English-language articles on solitary fibrous tumor of the ear, with emphasis on the tympanic membrane, published through 2022. A combination of Boolean operators and the following keywords were included in the search strategy: "solitary fibrous tumor", "tympanic membrane", and "ear". RESULTS: We found 12 previous reports of solitary fibrous tumors of the ears, none of which were in the tympanic membrane. All cases underwent surgical resection, with or without perioperative embolization, or radiation. There was no evidence of distant diseases in any cases. CONCLUSIONS: In the context of a tympanic membrane mass with associated pain and hearing loss, our findings suggest that solitary fibrous tumor should be included in the differential diagnosis.

Mastoid obliteration versus canal wall down or canal wall up mastoidectomy for cholesteatoma: Systematic review and meta-analysis.

BACKGROUND: There is ongoing debate over the optimal surgical approach for cholesteatoma treatment1-5. The aim of this review was to determine whether canal-wall down with mastoid obliteration is associated with favourable outcomes compared to either canal-wall down without obliteration or canal-wall up. The primary outcome was cholesteatoma reoccurrence with secondary outcomes including otorrhoea, reoperation and patient-reported outcome measures. METHODS: Medline, Embase, Cochrane databases and clinicaltrials.gov were searched for studies reporting outcomes of patients undergoing primary CWD-MO for cholesteatoma and directly compared with CWD and CWU mastoidectomies. Data were collated and meta-analysis performed. RESULTS: 2379 patients were included from 12 studies that met the inclusion criteria. CWD-MO was found to be associated with significantly less risk of recurrence when compared to CWU (OR = 0.330 (95 % CI 0.191-0.570, p < 0.001). When compared to CWD, CWD-MO was associate with significantly lower incidence of persistent otorrhoea (OR 0.405 (95 % CI 0.232-0.706, p < 0.001) while the rates of recurrence were comparable (OR: 1.231 [95 % CI: 0.550-2.757] p = 0.613). Otorrhoea rates between CWD-MO and CWU were equivalent as was reoperation. Quality of life and hearing outcomes were variably reported. CONCLUSIONS: This systematic review demonstrates that CWD-MO technique achieves lower recurrence rates comparable to CWD approaches and superior to CWU, while offering improved long-term control of otorrhoea. The final procedural choice should be decided based on surgeon experience, skill set and individual patient factors. To address the risk of selection bias, a randomised controlled trial is needed to answer this important research question.
