ABSTRACT
BACKGROUND: Epistaxis is a recurring cause for referral to emergency departments. Its management can be complex; hence, it is critical to provide appropriate support to Otolaryngology-Head and Neck Surgery (OHNS) residents to develop clinical reasoning skills to manage such cases. Learning-by-Concordance (LbC) is a recently developed educational tool that encourages learners to think through simulated clinical scenarios. A panel of ENTs provides insightful feedback to residents, reflecting a diversity of opinions about practice. Our study aimed to assess LbC's feasibility and perceived value for training OHNS residents in epistaxis management. METHODS: In this qualitative study, three OHNS surgeons, including two faculty members and one resident, wrote the LbC scenarios. The LbC tool was made available to participants through an online platform. A panel of four OHNS faculty provided feedback on answers to LbC questions. Otolaryngology-Head and Neck Surgery residents participated and provided their opinion on the value of this educational tool through an online questionnaire. RESULTS: A total of 10 one-hour sessions were required to create and upload the training tool. To provide insightful feedback embedded in the learning tool, the four panelists needed 60â min each. Of the 37 participating residents, 25 (68%) completed the training. Overall satisfaction was high: 88% appreciated the training method, and 92% wanted to use this type of training again. Most residents felt the training enabled them to improve their clinical reasoning when encountering a patient with epistaxis (92%) and their knowledge about epistaxis (96%). CONCLUSION: Findings suggest that OHNS residents could benefit from clinical reasoning exercises with panelist feedback using the LbC approach for clinical presentations that require complex approaches to manage conditions such as epistaxis.

BACKGROUND: Squamous cell carcinoma (SCC) of the temporal bone (TB) is a rare pathology originating from the external auditory canal (EAC). Surgery remains the gold standard to achieve local control.Aims/Objectives:The aim of this study was to evaluate overall survival (OS) and disease-free survival (DFS) after surgery of the SCC of EAC. MATERIAL AND METHODS: A retrospective chart review in a tertiary referral center included 26 patients: 23 were operated with lateral temporal bone resection (LTBR, n = 10) and extended temporal bone resection (ETBR, n = 13). The outcomes were OS and DFS. RESULTS: Adjuvant radiotherapy was performed in 91.3% (n = 21/23). Mean age was 60.8 and sex ratio was 1. Median follow-up was 43 months; The 5-years OS was 90% (± 9.5%) and 47.7% (± 12.9%) for stage I/II and III/IV respectively (p = .033). DFS was 67.6% (IC 95%, 51.4%-88.9%) without statistical difference between early advanced stage. Incomplete margins (p = .004) and Stage IV(p < .001) were associated with poorer DFS. Free margins significantly correlated with better OS (HR = 9.8, p = .04). CONCLUSION: En bloc surgical resection with free margins, coupled with postoperative radiotherapy, provides optimal local control. For stage IV tumors, where complete margins are achievable, ETBR is recommended to enhance local control.
ABSTRACT
OBJECTIVES: To analyse prognostic factors and survival outcomes of malignant tumors of the external auditory canal, to investigate the role of regional surgery, and adjuvant radiotherapy in early stages and to investigate the role of surgery in operable T4 stage. SETTING: A retrospective analysis was conducted on all patients prospectively included in the national database of the French Expertize Network for Rare ENT Cancers (REFCOR) from January 2000 to December 2016. PARTICIPANTS: 103 patients from 19 reference centers were included. A propensity score matching analysis was applied to enable comparisons between treatments. MAIN OUTCOMES AND MEASURES: Event-free survival, overall survival and factors of poor prognosis of the cohort were described. The interest of local and regional surgery and postoperative radiotherapy were evaluated. RESULTS: The factors of poor prognosis on event-free survival were immunosuppression (p = 0.002), Karnofsky status less than 90% (p = 0.02), body mass index less than 19 Kg / m2 (p = 0.0009), peripheric facial palsy (p = 0.0016), and positive margin (p = 0.0006). In early stages, locoregional surgery was associated with an increase in event-free survival (p = 0.003, HR = 0.21) versus local surgery alone, while postoperative radiotherapy was not associated with an increase in event-free survival (p = 0.86, HR = 0.91) or overall (p = 0.86, HR = 0.91). In locally advanced stages, locoregional surgery followed by radiotherapy was associated with an increase in event-free survival (p = 0.03, HR = 0.39) and overall (p = 0.02, HR = 0.34) versus chemoradiotherapy alone. CONCLUSION AND RELEVANCE: Regional surgery is recommended for early stages of cancers of the external auditory canal. In operable cases, locoregional surgery followed by radiotherapy is recommended.

To report the case of the simultaneous treatment of otosclerosis and malleus fixation through an entirely endoscopic transcanal approach. A targeted transcanalar epitympanotomy with annular bony ridge conservation was planned preoperatively, with 3D CT localization of the fixed part of the malleus head. The upper part of the malleus head and the superior ossified ligament of the malleus were drilled. A 0.6 mm stapedotomy was performed and a piston inserted. The patient's recovery was uneventful, with closure of the air-bone gap on her postoperative audiogram, associated with an overclosure in 500Hz, 1kHz, 2 kHz and 4 kHz.

BACKGROUND: The surgical treatment of otosclerosis consists of the replacement of the stapes using a piston. AIMS/OBJECTIVES: The objective of this study is to assess the audiometric results and quality of life (QOL) of patients who underwent surgery for otosclerosis by stapedectomy with fascia interposition (STIP) or by stapedotomy using CO2 laser (SLaser) without fascia interposition. MATERIAL AND METHODS: Ninety-one patients operated on for otosclerosis by STIP (40 patients) and by SLaser (51 patients) were included. Audiometric results were graphically displayed using the Amsterdam Hearing Evaluation Plot and were compared to the Common Otology Database (COD) comprising 660 patients. The patients' QOL was assessed with an otological validated survey. The significance level was p < .05. RESULTS: There was no significant difference in hearing improvement between SLaser and STIP-operated patients. There was no significant difference between our results and that of COD. QOL was significantly improved (+3.5/10) postoperatively for both STIP and SLaser in both social and professional fields. CONCLUSIONS AND SIGNIFICANCE: By comparing QOL and hearing gain of STIP and SLaser, our results suggest that both surgical techniques are a safe and successful treatment for otosclerotic stapes fixation. Further studies aiming at comparing larger series may confirm and refine these results.

OBJECTIVE: Chronic otitis media (COM) can seriously impact quality of life (QOL). Disease-specific questionnaires are essential for an accurate assessment of this impact. There is no questionnaire available for French-speaking patients with COM. This study aims to adapt and validate the French version of the COMQ-12 questionnaire. DESIGN: This is a controlled, prospective study, conducted between May 2020 and December 2021. Translation was performed using a forward-backward technique, and statistical validation was performed with a COM patients and a controls adult cohorts. STUDY SAMPLE: 100 patients (mean age 48 ± 16), and 50 controls (mean age 41 ± 16; p = 0.02) completed the test. RESULTS: Internal consistency, assessed by Cronbach's alpha, was 0.870 for the cases group. The mean COMQ-12 total score was 23.92 ± 11.3 for cases versus 3.70 ± 6.15 for controls (p < 0.0001). Individual items all had high discriminatory performances. The three items concerning ear discharge (Q1, Q2, Q9) had weaker correlation with the other items and the global score, but did not have a negative impact on internal consistency. CONCLUSION: The French version of the COMQ-12 is a short and easy-to-use test, with robust statistical properties, for assessing QOL in patients with COM.

Phaeohyphomycoses comprise a heterogeneous group of fungal infections caused by dematiaceous fungi and have primarily been reported in patients with underlying acquired immunodeficiencies, such as hematological malignancies or solid-organ transplants. Over the past decade, a growing number of patients with phaeohyphomycosis but otherwise healthy were reported with autosomal recessive (AR) CARD9 deficiency. We report a 28-year-old woman who presented with invasive rhinosinusitis caused by Alternaria infectoria. Following a candidate gene sequencing approach, we identified a biallelic loss-of-function mutation of CARD9, thereby further broadening the spectrum of invasive fungal diseases found in patients with inherited CARD9 deficiency. In addition, we reviewed 17 other cases of phaeohyphomycosis associated with AR CARD9 deficiency. Physicians should maintain a high degree of suspicion for inborn errors of immunity, namely CARD9 deficiency, when caring for previously healthy patients with phaeohyphomycosis, regardless of age at first presentation.
ABSTRACT
PURPOSE: In chronic otitis media (COM), disease chronicity and severity of middle ear inflammation may influence the development of inner ear deficits, increasing the risk of vestibular impairment. This secondary analysis of the multinational collaborative Chronic Otitis Media Questionnaire-12 (COMQ-12) dataset sought to determine the prevalence of vestibular symptoms in patients with COM and identify associated disease-related characteristics. METHODS: Adult patients with a diagnosis of COM in outpatient settings at nine otology referral centers across eight countries were included. We investigated the presence of vestibular symptoms (dizziness and/or disequilibrium) using participant responses to item 6 of a native version of the COMQ-12. Audiometric data and otoscopic assessment were also recorded. RESULTS: This analysis included 477 participants suffering from COM, with 56.2% (n = 268) reporting at least mild inconvenience related to dizziness or disequilibrium. There was a significant association between air conduction thresholds in the worse hearing ear and presence of dizziness [adjusted odds ratio (AOR), 1.01; 95% CI 1.00-1.02; p = 0.0177]. Study participants in European countries (AOR 1.53; 95% CI 1.03-2.28; p = 0.0344) and Colombia (AOR 2.48; 95% CI 1.25-4.92; p = 0.0096) were more likely to report dizziness than participants in Asian countries. However, ear discharge and cholesteatoma showed no association with dizziness in the adjusted analyses. CONCLUSION: Vestibular symptoms contribute to burden of disease in patients with COM and associates with hearing disability in the worse hearing ear. Geographical variation in presentation of dizziness may reflect financial barriers to treatment or cultural differences in how patients reflect on their health state.

OBJECTIVE: This study aimed to assess how two disease-related factors, hearing disability and ear discharge, affect health-related quality-of-life (HRQoL) in patients with chronic otitis media (COM). STUDY DESIGN: Multinational prospective cohort study. SETTING: Nine otology referral centers in eight countries. PATIENTS: Adult patients suffering from COM. MAIN OUTCOME MEASURES: Hearing disability and ear discharge were assessed by audiometry (Department of Health and Social Security formula) and otoscopy, respectively. Participants completed a native version of the Chronic Otitis Media Questionnaire-12 (COMQ-12). We determined how the two disease-related factors affect HRQoL by performing two separate analyses: (1) using a 6-item score combining responses to COMQ-12 items independent of hearing loss and ear discharge and (2) using item 12 alone as a proxy for global HRQoL. RESULTS: This study included 478 participants suffering from COM. There was a significant association between HRQoL and hearing disability in the adjusted analysis. For every unit increase in the Department of Health and Social Security average hearing threshold (1) there was an increase of 0.06 (95% CI [0.007, 0.121], pâ=â0.0282) in the 6-item score and (2) the adjusted odds of having a higher item 12 score was 1.03 (95% CI [1.01, 1.04], pâ=â0.0004). There was no association between the presence of ear discharge and HRQoL in both COMQ-12 score analyses. CONCLUSIONS: Knowledge of disease-related factors that influence HRQoL will aid interpretation of patient-reported measures for COM. Patients with a greater degree of hearing impairment appear to have poorer HRQoL, which is not exacerbated by the presence of ear discharge. The magnitude of postoperative hearing improvement rather than the attainment of a dry ear may be a better indicator of surgical success from the patient's perspective.

PURPOSE: Patients with superior semicircular canal dehiscence syndrome, which can only be treated by surgery, present cochleo-vestibular symptoms related to a third-mobile window but also endolymphatic hydrops. Since cVEMP and oVEMP are disturbed by the presence of the dehiscence, the aim of the study is to assess the value of MRI for the diagnosis of endolymphatic hydrops in patients with superior semicircular canal dehiscence syndrome in comparison with cVEMP and oVEMP. METHODS: In this retrospective cohort study we enrolled 33 ears in 24 patients with superior semicircular dehiscence syndrome who underwent a 4-h delayed intravenous Gd-enhanced 3D-FLAIR MRI and pure tone audiometry, cVEMP and oVEMP. For each patient MRI images were evaluated by two radiologists who used a compartmental endolymphatic hydrops grading system in comparison with cVEMP and oVEMP. RESULTS: Endolymphatic hydrops was found on MRI in 9 out of 33 SCDS ears (27.3%). We found no significant correlation between the presence of endolymphatic hydrops on MRI and cVEMP and oVEMP (p = 0.36 and p = 0.7, respectively). However, there was a significant correlation between the presence of endolymphatic hydrops on MRI and the degree of sensorineural hearing loss, Air Conduction-Pure Tone Average level (p = 0.012) and Bone Conduction-Pure Tone Average level (p = 0.09), respectively. CONCLUSION: We demonstrated that EH might be observed in 27.3% of superior semicircular dehiscence syndrome ears. The role of inner ear MRI is important to detect endolymphatic hydrops, since cVEMP and oVEMP are disturbed by the presence of the dehiscence, because these patients could benefit from a medical treatment. LEVEL OF EVIDENCE: Level 3.

PURPOSE: To describe and analyse functional treatment of temporal bone chondroblastoma (TBCh). METHODS: From January 2000 to June 2019, at the Department of Otorhinolaryngology, Hôpital Lariboisière, Paris, France, patients with TBCh were enrolled in this study. All cases routinely performed pre-operatory work-up including evaluation of performance status, audio-vestibular function test, ear endoscopy, contrasted CT scan and MRI of head and neck region; in one case we also performed an angio-CT scan. All patients underwent resection of the tumour with a "functional" approach RESULTS: Three male patients (mean age 46,6 years)-two primary tumours and one recurrence-were treated. In all three cases the tumour invaded the middle ear with a variable degree of hearing loss and infiltration of temporal bone structures. All surgeries were performed with a microscopic approach associated with open/endoscopic approach when necessary. Inner ear and facial nerve were speared in all cases and the TMJ was partially resected in 2 cases due to its moderate involvement. At present, after a mean follow-up of 103 months (range 40-225 months), only one case presented recurrence which has been successfully treated with radiotherapy. CONCLUSIONS: Our results of treatment suggest that functional surgery can be relevant in the management of TBCh since it is focused on both treatment of this pathology and maintenance of a good quality of life.

OBJECTIVE: Preoperative embolization of juvenile nasopharyngeal angiofibroma (JNA) is usually performed by the occlusion of branches of the external carotid artery (ECA). However, a significant proportion of JNAs also receive blood from the internal carotid artery (ICA). The objective of this study was to report on the feasibility and clinical impact of superselective embolization of ICA branches in complex cases of JNA. METHODS: This was a single-center retrospective study of all patients operated on for JNA between 2000 and 2018. The patients treated with embolization of branches of the ICA were identified. The results in terms of complications, intraoperative blood loss, and rate of residual disease were analyzed and compared to those of a control group of patients treated only with embolization of ECA branches and matched by age, stage, angiographic pattern, surgical approach, and previous surgery. RESULTS: Ninety-two patients were included. Embolization of branches of the ICA was attempted in 14 cases of advanced or recurrent tumors and was ultimately possible in nine cases. There were no complications after embolization. The mean intraoperative blood loss was 1428 mL. Residual disease was found in three cases (33%). There was no significant difference compared with the control group (mean intraoperative blood loss = 1355 mL, residual disease = 4 (44%); all P > .05). CONCLUSION: In this retrospective study, we report the feasibility of superselective embolization of ICA branches in selected cases of JNA. There was no observed benefit of this technique in terms of intraoperative bleeding or decreased risk of residual disease. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E775-E780, 2021.

OBJECTIVES: The Chronic Otitis Media Questionnaire-12 (COMQ-12) assesses patient-reported health-related quality of life. A multinational collaborative project was performed to translate and appraise the psychometric properties of the COMQ-12 across Europe, Asia, and South America. METHODS: Eight otology units from seven countries (China, Colombia, France, Italy, Japan, Korea, Turkey) created native versions of the COMQ-12 by the process of translation and back-translation. Questionnaire reliability was assessed on the basis of internal consistency by calculating Cronbach's coefficient alpha. Exploratory factor analysis was performed to identify underlying correlations between individual questionnaire items. RESULTS: This study included 478 participants from 8 countries. Calculated values for Cronbach's coefficient alpha were between 0.71 and 0.90. Exploratory factor analysis allowed the identification of three dominant factors, the primary factor (related to hearing problems) explaining 42% of the total variance, the secondary factor (related to daily activities) explaining 30% of the variance, and the third factor (related to acute disease activity) explaining 28% of the variance. CONCLUSIONS: This is a large study of patients with chronic otitis media, from centers from within many different countries spanning Europe, Asia, and South America. This study supports the use of the COMQ-12 within the individual countries where it was tested.

BACKGROUND: The roles of thrombophilia and cardiovascular risk factors in sudden sensorineural hearing loss (SSNHL) remain controversial. Cochlear microthrombosis and vasospasm have been hypothesized as possible pathogenic mechanisms of SSNHL. This article investigates the circulating serotonin and homocysteine levels besides thrombophilia screening in patients with idiopathic SSNHL. METHODS: A total of 133 SSNHL patients and age- and sex-matched controls were investigated (discovery cohort). Measurement included common inherited natural coagulation inhibitors, factor VIII, von Willebrand factor (VWF), antiphospholipid antibodies, homocysteine, and serotonin (whole blood, platelet, and plasma) levels, along with frequent relevant genetic variants. A validation cohort (128 SSNHL patients) was studied for homocysteine and serotonin levels. RESULTS AND CONCLUSION: In the discovery cohort, 58.6% of patients exhibited thrombophilia, of which most had a low to moderate titers of antiphospholipid antibodies and high levels of factor VIII/VWF. Twenty-seven patients (20%) had mild-to-moderate hyperhomocysteinemia or were homozygous for the methylenetetrahydrofolate reductase (MTHFR) C677T mutation. Regarding serotonin, SSNHL patients had elevated whole blood levels that remained within the normal range and normal platelet content. However, approximately 90% patients of both cohorts had elevated plasma serotonin. Elevated plasma serotoninemia was accompanied by serotonylation of platelet rhoA protein. This study shows that increased plasma serotonin appears as a biomarker of SSNHL (specificity: â¼96%, sensitivity: â¼90%) and could participate in the pathophysiology of SSNHL.

Background: We previously described that adenoid tissue in children with chronic otitis media (COM) contained more mucosal biofilms than adenoid tissue removed for hypertrophy.Aims/objectives: The aim of the second part was to characterize nasopharyngeal microbiota and explore virulence of the most common middle ear pathogens.Material and methods: Bacteriological analysis was performed following a culture-based approach on the samples recovered from 30 patients of COM group (15 biofilm-positive and 15 biofilm-negative) and from 30 patients of a control group (15 biofilm-positive and 15 biofilm-negative). Virulence factors of Streptococcus pneumoniae, Streptococcus pyogenes, and Haemophilus influenzae were investigated.Results: The most frequent species were Firmicutes followed by Proteobacteria and Actinobacteria. The presence of biofilm was statistically associated with an increase of the number of bacterial species and Firmicutes phylum regardless of the condition (case/control). No virulence factors associated with invasive isolates were found for the most common middle ear pathogens.Conclusions and significance: This case-control study demonstrated that the presence of COM plus biofilm was associated with a given microbiota which contained more Firmicutes. Our study allows a better understanding of physiopathological mechanisms involved in chronic otitis media and paves the way for further investigations.

PURPOSE: Bilateral vestibulopathy (BV) is an uncommon disorder and the etiology remained idiopathic in most cases. Delayed 3D-FLAIR sequences have provided new insights into various inner ear diseases, allowing the evaluation of the endolymphatic space and the permeability of the blood-labyrinthine barrier (BLB). The aim of this study was to assess both the morphology of the endolymphatic space and the permeability of the BLB in patients with BV as evaluated by delayed 3D-FLAIR sequences. METHODS: In this retrospective study, we performed 3D-FLAIR sequences 4 h after administering contrast media to 42 patients with BV. Two radiologists independently evaluated the morphology of the endolymphatic space (either vestibular atelectasis or endolymphatic hydrops) and the permeability of the BLB. RESULTS: Morphologic anomalies of the endolymphatic space and vestibular blood-labyrinthine barrier impairment were observed in 59.6% of patients with BV. Bilateral vestibular atelectasis (VA) was found in 21 patients (50%), involving only the utricle and all three ampullas while the saccule was always observed with no sign of collapse: idiopathic BV (n = 19), aminoglycoside administration (n = 1) and few days following abdominal surgery (n = 1). One patient had bilateral vestibular malformation. BLB impairment was observed in five patients (11.9%): paraneoplastic (n = 1), lymphoma (n = 1), autoimmune (n = 1), and vestibular "neuritis" (n = 2). Seventeen patients (40.4%) had normal MRI with no endolymphatic space anomaly or BLB impairment. CONCLUSION: Patients with BV presented with morphologic anomalies of the endolymphatic space or BLB impairment in 59.6% of patients.
