Is a Simple Checklist Associated With Improvement in Gender Representation at the AAO-HNSF Annual Meeting?

In September 2017, the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) added 2 questions querying panel organizers if gender/racial diversity was considered in selecting panel presenters, beginning with the 2018 Annual Meeting (AM). This study examines how this checklist impacted the gender diversity of panel presenters at the AAO-HNS AM. This was a cross-sectional investigation comparing female representation before and after the addition of questions inquiring about diversity in 2018. A review of abstract submissions for the AMs from 2015 to 2021. AM Official Program Abstracts were used to obtain presenter names and specialty area for each panel. The percentage of female presenters, in total and stratified by specialty area, were compared before and after 2018 to quantify changes following the addition of the checklist. There was a significant increase in the proportion of female panel presenters from 22.3% (total n = 1199) in 2015 to 2017 to 33.0% (total n = 1868) in 2018 to 2021 (P < .001) and in all panel specialties. The number of female moderated panels also significantly increased after checklist implementation from 22% to 38% (P < .001). Correspondingly, the number of panels with no female representation decreased from 42% in 2015 to 2017 to 23% in 2018 to 2021 (P < .001). The addition of a checklist asking panel organizers to consider diversity in selecting panelists was associated with an increased proportion of female presenters at the AM. This simple strategy can be implemented by all medical conferences to help close the gender gap.

Female leadership representation within otolaryngology specialty societies

ObjectivesDetermine if women have continued parity in leadership in otolaryngology specialty societies as compared to a paper by Choi and Miller in 2012. Additionally, we wanted insight into obstacles female leaders faced by surveying them directly to better understand their experiences with gender bias. MethodsChi-squared test evaluation was done using the American Academy of Otolaryngology Head and Neck Surgery (AAOHNS) 2020 membership data and directly from various otolaryngology specialty societies. An anonymous survey to assess different experiences of leaders in various Otolaryngology specialty societies was sent to current and past leaders of specialty societies via email. Survey data was assessed using descriptive statistics and multivariate logistical analyses. Study Design: Cross-sectional study and survey study. ResultsFemale members comprised 19.3 % of practicing AAOHNS otolaryngologists. All societies had proportionate female leadership representation except for AAOA, which had greater representation. Compared to data from 10 years ago, female representation in all the societies' leadership has not changed significantly. Survey results demonstrated 64.9 % of respondents felt gender bias exists in Otolaryngology. 45.6 % of respondents personally experienced gender bias during their careers. Survey results showed males are less likely to experience gender bias. ConclusionThere is stability in the proportion of women in otolaryngology leadership positions compared to a decade ago largely due to efforts of leaders in the field. However, women leaders note experiencing gender bias and time away from clinical duties are prospective areas where support can be given. Level of evidence3.

Establishment of Nomogram for Prediction of Hearing Preservation after Retrosigmoid Approach in Patients with Vestibular Schwannoma.

To derive and validate a prognostic nomogram for the prediction of hearing preservation (HP) after retrosigmoid approach (RSA) in patients with vestibular schwannoma (VS) and further assist in clinical decision-making. Retrospective study. Tertiary referral center. A total of 111 patients diagnosed with VS with serviceable hearing from January 2013 to March 2023. All patients underwent surgery via RSA, and hearing outcomes were reviewed 2 weeks postoperatively. Preoperative and postoperative hearing were analyzed and stratified according to the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS). In multivariate analysis of the primary group, preoperative hearing, tumor size, and tumor origin were significantly related to postoperative HP ( p = 0.029, p = 0.043, and p = 0.018, respectively). Factors derived from the multivariate analysis were all assembled into the nomogram. The receiver operating characteristic (ROC) curves showed good predictive accuracy of the nomogram model in both primary and validation groups with area under the ROC curve (AUC) values of 0.802 and 0.797, respectively. Independent predictors of postoperative HP in patients with VS were selected to create the nomogram. The nomogram was able to stratify patients into different risk groups and assist in clinical decision making.

The Effect of Rivaroxaban in the Complementary Therapy of Sudden Sensorineural Hearing Loss

Abstract Background: Due to the importance of sudden sensorineural hearing loss (SSNHL) and the possible role of blood coagulation in its mechanism and the likely therapeutic effect of anticoagulants and also the lack of studies in this field, this study aimed to evaluate the effect of rivaroxaban (RXA) in the treatment of this disease. Materials and Methods: The present double-blind randomized clinical trial study was performed on 34 patients with SSNHL. Patients were randomly divided into two groups. In the first group, in addition to corticosteroid therapy (CST), RXA 10 mg tablets were used daily for 10 days (RXA group), and in the second group, only CST (CST group) treatment was prescribed. Hearing recovery was then assessed and recorded according to the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) criteria. Results: This study showed that the grade of hearing recovery in the RXA group (58.8%) was higher than the CST group (47.1%), but this difference was not significant (P value &gt;0.05). Also, RXA treatment increased the odds of hearing recovery, and this difference was not statistically significant (odd ratio (95% confidence interval)(OR (95% CI): 2.327 (0.180–18.082); P value = 0.518). In contrast, delay to treatment, more increased PTA (pure tone average (PTA)), and having vertigo reduced the odds of hearing recovery by 0.138-, 0.019-, and 0.069-fold, respectively (P value &lt;0.05). Conclusion: According to the results of this study, although the percentage of hearing recovery was higher in the RXA group, in general, the results of the two treatments were not significantly different.

New Medical Device and Therapeutic Approvals in Otolaryngology: State of the Art Review of 2022.

To review new drugs and devices relevant to otolaryngology approved by the Food and Drug Administration (FDA) in 2022. Publicly available FDA data on drugs and devices approved in 2022. A preliminary screen was conducted to identify drugs and devices relevant to otolaryngology. A secondary screen by members of the American Academy of Otolaryngology-Head and Neck Surgery's (AAO-HNS) Medical Devices and Drugs Committee differentiated between minor updates and new approvals. The final list of drugs and devices was sent to members of each subspecialty for review and analysis. A total of 1251 devices and 37 drugs were identified on preliminary screening. Of these, 329 devices and 5 drugs were sent to subspecialists for further review, from which 37 devices and 2 novel drugs were selected for further analysis. The newly approved devices spanned all subspecialties within otolaryngology. Many of the newly approved devices aimed to enhance patient experience, including over-the-counter hearing aids, sleep monitoring devices, and refined CPAP devices. Other advances aimed to improve surgical access, convenience, or comfort in the operating room and clinic. Many new devices and drugs are approved each year to improve patient care and care delivery. By staying up to date with these advances, otolaryngologists can leverage new innovations to improve the safety and quality of care. Given the recent approval of these devices, further studies are needed to assess long-term impact within the field of otolaryngology.

"The Pedagogical Legacy of Dr. Chevalier Jackson: An Archival Visit to the John Q. Adams History Center at the American Academy of Otolaryngology-Head and Neck Surgery".

This article explores the historic records of the American Academy of Otolaryngology-Head and Neck Surgery's (AAO-HNS) John Q. Adams Center for the History of Otolaryngology-Head and Neck Surgery, with particular attention paid to the Dr. Chevalier Jackson Collection. The library houses diverse materials that would be of interest to medical historians seeking to understand the early innovations in our specialty. With a repository of over 2200 items chronicling over 200-years of otolaryngological history, the library contains special collections dedicated to Drs. Maurice H. Cottle, Samuel Rosen, Adam Politzer, and Chevalier Jackson. An original aim of this visit sought to understand Dr. Jackson's early contributions to the fields of laryngology, bronchology, and esophagology; yet, an intimate review of his works, including autobiographical material, reveals a fascinating pedagogical legacy.

Eugene Nicholas Myers' Lecture on Head and Neck Cancer, 2020: The Surgeon as a Prognostic Factor in Head and Neck Cancer Patients Undergoing Surgery.

This paper is a transcript of the 29 th Eugene N. Myers, MD International Lecture on Head and Neck Cancer presented at the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) in 2020. By the end of the 19 th century, the survival rate in treated patients was 10%. With the improvements in surgical techniques, currently, about two thirds of patients survive for > 5 years. Teamwork and progress in surgical reconstruction have led to advancements in ablative surgery; the associated adjuvant treatments have further improved the prognosis in the last 30 years. However, prospective trials are lacking; most of the accumulated knowledge is based on retrospective series and some real-world data analyses. Current knowledge on prognostic factors plays a central role in an efficient treatment decision-making process. Although the influence of most tumor- and patient-related prognostic factors in head and neck cancer cannot be changed by medical interventions, some environmental factors-including treatment, decision-making, and quality-can be modified. Ideally, treatment strategy decisions should be taken in dedicated multidisciplinary team meetings. However, evidence suggests that surgeons and hospital volume and specialization play major roles in patient survival after initial or salvage head and neck cancer treatment. The metrics of surgical quality assurance (surgical margins and nodal yield) in neck dissection have a significant impact on survival in head and neck cancer patients and can be influenced by the surgeon's expertise. Strategies proposed to improve surgical quality include continuous performance measurement, feedback, and dissemination of best practice measures.

Cerebral Outflow Discrepancies in Recurrent Benign Paroxysmal Positional Vertigo: Focus on Ultrasonographic Examination.

This prospective pilot study aimed to evaluate whether cerebral inflow and outflow abnormalities assessed by ultrasonographic examination could be associated with recurrent benign paroxysmal positional vertigo (BPPV). Twenty-four patients with recurrent BPPV, affected by at least two episodes, and diagnosed according to American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria, evaluated at our University Hospital, between 1 February 2020 and 30 November 2021, have been included. At the ultrasonographic examination, 22 of 24 patients (92%) reported one or more alterations of the extracranial venous circulation, among those considered for the diagnosis of chronic cerebrospinal venous insufficiency (CCSVI), although none of the studied patients were found to have alterations in the arterial circulation. The present study confirms the presence of alterations of the extracranial venous circulation in recurrent BPPV; these anomalies (such as stenosis, blockages or regurgitation of flow, or abnormal valves, as per the CCSVI) could cause a disruption in the venous inner ear drainage, hampering the inner ear microcirculation and then possibly causing recurrent otolith detachment.

CyberKnife Stereotactic Radiosurgery for Growing Vestibular Schwannoma: Longitudinal Tumor Control, Hearing Outcomes, and Predicting Post-Treatment Hearing Status.

(1) To determine tumor control rates for treating growing vestibular schwannoma (VS) with CyberKnife stereotactic radiosurgery (CK SRS); (2) to determine hearing outcomes after CK SRS; (3) to propose a set of variables that could be used to predict hearing outcomes for patients receiving CK SRS for VS. Retrospective case series review. 127 patients who received CK SRS for radiographically documented growing VS were reviewed. Tumors were monitored for post-procedure growth radiographically with linear measurements and three-dimensional segmental volumetric analysis (3D-SVA). Hearing outcomes were reviewed for 109 patients. Cox proportional hazard modeling was used to identify variables correlated with hearing outcomes. Tumor control rate was 94.5% for treating VS with CK SRS. Hearing outcomes were categorized using the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) classification system. As of their last available audiogram, 33.3% of patients with pre-treatment class A and 26.9% of patients with class B retained their hearing in that class. 15.3% of patients starting with class A or B with extended follow-up (>60 months), maintained hearing within this same grouping. Our final model proposed to predict hearing outcomes included age, fundal cap distance (FCD), tumor volume, and maximum radiation dose to the cochlea; however, FCD was the only statistically significant variable. CK SRS is an effective treatment for control of VS. Hearing preservation by class was achieved in a third of patients. Finally, FCD was found to be protective against hearing loss. 4 Laryngoscope, 134:S1-S12, 2024.

Association of Dizziness-Related Handicap or Disability with Clinical Features in Patients with Early Parkinson's Disease.

Complaining of dizziness is common in patients with Parkinson's disease (PD) even at the early phase of the disease. Therefore, regarding motor or non-motor symptoms, clinical implication of subjective dizziness in early Parkinsonian patients is needed to be explored. Eighty patients diagnosed with early PD (defined by disease duration of five years or less) were retrospectively enrolled for the study. Dizziness handicap inventory (DHI), the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) Functional Level Scale (FLS), and clinical features of parkinsonian motor and non-motor symptoms using representative measurements. Through simple and multiple linear regression analyses, we found that both DHI and FLS were significantly and positively correlated with postural instability/gait disorder (PIGD) score but negatively with the Montreal cognitive assessment (MoCA) score. We found that subjective dizziness in patients with early PD was related to not only axial symptoms of PIGD, but also global cognitive function of MoCA. Further research is required to confirm our results.

Management, Referral Patterns, and Outcomes in Bell's Palsy: A Single-Institution 903 Patient Series.

In 2013, the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) published guidelines for Bell's palsy (BP), including recommendations for workup, management, and specialist referral. Patients with BP often present to primary care; however, adherence to guidelines may vary by setting. This study sought to evaluate the management of patients with BP presenting to primary care, emergency department (ED), and urgent care settings. Retrospective cohort study. Tertiary care center. Retrospective chart review of patients identified by diagnosis code for BP. A total of 903 patients were included; 687 (76.1%) presented to ED, 87 (9.6%) to internal medicine, 77 (8.5%) to family medicine, and 52 (5.8%) to urgent care. On presentation, 804 (89.0%) patients were prescribed corticosteroids and 592 (65.6%) antiviral therapy. Steroid therapy ranged from 1 dose to greater than a 14-day course, with 177 (19.6%) receiving an adequate duration of 10 days or greater. Referrals were provided to facial plastics and/or otolaryngology for 51 patients (5.6%). For all comers, 283 (31.3%) had complete resolution, 197 (21.8%) had an incomplete resolution, 62 (6.9%) had persistent palsy, and 361 (40.0%) lost to follow-up. In assessing the association between clinic setting and management, appropriate corticosteroid therapy (p < .01), imaging (p < .01), and eye care (p < .01) were statistically significant. Adherence to guidelines for BP management varies amongst providers. In our study cohort, 15.5% of patients received medical therapy in accordance with AAO-HNS guidelines, and only 5.6% were referred to facial plastics. To facilitate more appropriate care, tertiary care institutions may benefit from system-wide care pathways to manage acute BP.

Guideline Adherence to Benign Paroxysmal Positional Vertigo Treatment and Management in Primary Care.

To determine adherence to the 2017 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines for the management and treatment of benign paroxysmal positional vertigo (BPPV) in primary care (PC) and compare whether key recommendations differed by sex, race, or insurance status. Retrospective chart review. Twenty-six clinic locations within a single healthcare system. Charts of 458 patients diagnosed with BPPV in PC between 2018 and 2022 were reviewed. Encounters where the diagnosis of BPPV was made were identified. From the clinical encounter note, demographics, symptomatology, management, and treatment were extracted. Nonparametric analyses were used to identify whether AAO-HNS guidelines differed regarding sex, race, or insurance status. Of 458 patients, 249 (54.4%) did not receive a diagnostic exam, and only 4 (0.9%) patients received imaging. Regarding treatment, only 51 (11.1%) received the Epley maneuver, with 263 (57.4%) receiving vestibular suppressant medication and 12.4% receiving a referral to a specialist. In regard to sex, race, or insurance status, there was no significant difference in receiving a Dix-Hallpike diagnostic maneuver, Epley maneuver, vestibular suppressant medication, imaging, or referral to a specialist. Our data suggestthat there continue to be gaps in the adherence to AAO-HNS guidelines; however, these gaps did not differ by sex, race, or insurance status. Care should be taken to increase the use of diagnostic and treatment maneuvers but decrease the use of vestibular-suppressant medications for the treatment of BPPV in PC.

Surgery for Otitis Media with Effusion: A Survey of Otolaryngologists Who Treat Children in Brazil.

Introduction  Myringotomy and ear tube placement (MTP) is the surgical treatment for otitis media with effusion (OME), and it is the most common surgery performed in children. Several guidelines have been developed to assist in the care of patients who become candidates for MTP. Objectives  To evaluate the practice of Brazilian otorhinolarynogologists when performing MTP according to the years of clinical experience. Secondarily, we also want to assess if their practice regarding MTP varied according to the percentage of children treated and the location of their practice. Methods  A 30-question survey was sent to otolaryngologists affiliated with the Brazilian Academy of Pediatric Otorhinolaryngology (Academia Brasileira de Otorrinolaringologia Pediátrica, ABOPe, in Portuguese) and/or the Scientific Department of Otorhinolaryngology of the Brazilian Society of Pediatrics (Sociedade Brasileira de Pediatria, SBP, in Portuguese). The questions included were carefully chosen to provide a profile about the practices adopted in the pre-, peri- and postoperative periods of MTP. Results  The questionnaire was sent to 208 otolaryngologists, and there were 124 (59.6%) respondents. Of those, 59.7% use antiseptics before surgery. Only 54 otolaryngologists, less than half of the subjects in this study (43.5%), always place a tube during the procedure. More physicians who practice in small cities recommend water precautions after MTP when compared to other physicians ( p  < 0.001). Conclusion  The present study reveals that many respondents do not follow some of the recommendations of the current guidelines of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) on OME, either perioperatively and postoperatively, or regarding the option of placing a ventilation tube. This part of the care also varied depending on the respondents' work location and experience in the medical practice.

Noise-induced hearing loss profile among Taiwan Airforce on duty pilots

PurposeNoise-induced hearing loss (NIHL) often results in impaired functional hearing and accidental injuries; thus, reducing military performance and endangering flight safety. While a few studies addressing laterality (left-right ear differences) and NIHL incidence between fixed-winged (jet-fighter) and rotary-wing (helicopter) aircrafts yielded inconsistent results, little is known about the NIHL profile among different types of jet-fighter pilots. This study aims to conduct a fine-grained examination of NIHL among Airforce jet pilots, with planned comparisons of laterality and aircraft type, along with the goal to compare the sensitivity of different hearing indices in predicting military pilot NIHL. Materials and methodsThis cross-sectional study utilizes the health and hearing data of 1025 Taiwanese Air Force Military pilots from the 2019 Taiwanese physical examination database to assess the changes in their hearing thresholds, and evaluate their risk for NIHL. ResultsOur results showed that, among available military aircraft types, the trainer aircraft and M2000-5 jet-fighter had the highest risk of NIHL, in addition to a left ear inferiority found in the overall population of military pilots. Among the three hearing indices used in this study –the International Organization for Standardization (ISO) three-point hearing index, the Occupational Safety and Health Administration (OSHA) three-point hearing index, and the American Academy of Otolaryngology-Head and Neck Surgery's (AAO-HNS) high-frequency three-point hearing index–, the OSHA the AAO-HNS were the most sensitive. ConclusionOur results suggest a better noise protection for trainer and M2000-5 pilots, especially for the left ear, is warranted.

World Voice Day 2023

World Voice Day 2023 Robert T. Sataloff (bio) CARE OF THE PROFESSIONAL VOICE Each year, the journal of singing publishes an issue highlighting World Voice Day. The journal is committed to collaborating with the American Academy of Otolaryngology—Head and Neck Surgery (AAO-HNS), the Voice Foundation, and other organizations to support World Voice Day. This article is modified periodically and republished before World Voice Day (April 16th) in order to remind people to prepare to participate in its commemoration. This topic has been discussed previously by the author and others (see References). All singing and acting teachers, physicians, speech-language pathologists, nurses, voice patients, and others who care for and about the voice, should work together to raise awareness of the importance of the voice and of developments in voice care. Some years ago, the World Health Organization (WHO) recognized a particularly high rate of laryngeal cancer in Brazil. In April, 1989, the Executive Committee of the Sociedade Brasileira de Laringologia e Voz (Brazilian Association of Laryngology and Voice), a multidisciplinary society that includes physicians, speech-language pathologists and singing teachers, proposed April 16th as “Voice Day.” Later, that idea was transformed to a national voice week, and even a voice month in some locations. Soon, other societies around the world recognized the importance of public education about voice; and the European Laryngological Association (www.elsoc.org), the American Academy of Otolaryngology-Head and Neck Surgery (AAOHNS) (www.entnet.org), the Voice Foundation (www.voicefoundation.org), the American Laryngological Association (ALA) (www.alahns.org), American Bronchoesophagological Association (www.abea.net), the National Association of Teachers of Singing (www.nats.org), and other organizations began collaborating to establish an annual celebration of voice. The AAO-HNS recognized this event in 2002, and the name World Voice Day was adopted. World Voice Day was celebrated in the United States for the first time on April 16, 2003, supported by the AAO-HNS, the Voice Foundation, the American Laryngological Association, the National Association of Teachers of Singing, and numerous other societies and organizations. A summary of the evolution of World Voice Day can be found on the website of the AAO-HNS, at World-Voice-Day.org, and in a 2007 editorial by Svec and Behlau. Typically, World Voice Day activities include lectures, concerts, educational programs, clinical voice screenings, and media events scheduled to take place on and around April 16th. Web-based educational initiatives may be found through the AAO-HNS, Voice Foundation and World-Voice-Day.org websites, and elsewhere. Laryngologists, speech-language pathologists, [End Page 483] nurses, singers, singing teachers, actors, acting teachers and others organize celebratory events in cities throughout the world. Voice professionals are bound together by a commitment to expand public appreciation of and knowledge about the human voice, and to raise awareness about the importance of good voice health and education. For example, in Philadelphia, Voice Foundation World Voice Day events have included a PECO Crown Lights display visible throughout much of the city, singing performances, and lectures on voice care, readings for children at venues such as libraries, stand-up comedy performances, cabaret events, and other activities. Extensive events honoring World Voice Day take place each year in Lisbon, Portugal, under the auspices of Professor Mario Andrea; in the Detroit area under the guidance of Dr. Adam Rubin; in Pittsburgh with Dr. Libby Smith; in San Francisco with Drs. Clark Rosen and VyVy Young; in Los Angeles under the guidance of Dr. Michael Johns; in Cleveland through Dr. Michael Benninger; in Paris with Dr. Jean Abitbol; in Beirut under the supervision of Dr. Abdul Hamdan; and in many other cities. In addition to the physician-led events, the National Association of Teachers of Singing supports World Voice Day actively, and many events throughout the United States are organized by singing teachers, as well as by speech-language pathologists and other voice professionals. Future activities are likely to be even more expansive. Many will be coordinated through the relatively new ad hoc World Voice Day planning committee, notable for its broad international representation. The group’s initial meeting was held in Erlangen, Germany, on July 4, 2012; and the organization is committed to sharing...

Clinical decision making in paediatric otitis media: A pilot quality improvement study.

This study aimed to improve local management of paediatric otitis media using the 2022 American-Academy of Otolaryngology Head and Neck Surgery (AAO-HNS) Clinical Practice Guideline for Tympanostomy Tubes in Children. A SQUIRE 2.0 compliant quality improvement study was carried out within the outpatient department of our otolaryngology tertiary referral centre. Local outpatient management of paediatric otitis media was compared to the AAO-HNS guidelines, specifically focussing on the decision to offer tympanostomy tubes. Following initial audit of practice, an educational session was performed within the otolaryngology department and local practice was subsequently re-evaluated. Overall, 88 children were included (46 pre-intervention and 42 post-intervention) with a mean age of 7.6 years (range 1-12 years). Sixty-four (72.7%) children presented with suspected otitis media with effusion. The remainder presented with recurrent or persistent acute otitis media (24/88, 27.3%). Twenty-six children were offered tympanostomy tubes (29.5%). Initial evaluation of practice identified that the decision to offer tympanostomy tubes was guideline appropriate in 76.1% of children (35/46). This significantly improved following an educational session (40/42, 95.2%, p=0.02). The reasons for non-guideline compliance included: otitis media with effusion <3 months, no evidence of middle ear fluid and patients meeting criteria for tympanostomy tube insertion not being offered. A focussed educational intervention may improve local adherence to guidelines in the management of paediatric otitis media. Continued re-evaluation of local practice is essential in order to ensure children are managed in accordance with the guidelines.

Factors associated with hearing outcomes after a middle fossa approach in 131 consecutive patients with vestibular schwannomas.

The middle fossa approach is an effective option for the treatment of small (Koos grade I and II) vestibular schwannomas (VSs) when the goal is hearing preservation. The authors evaluated the rates of hearing preservation and examined the factors associated with improved hearing outcomes after the middle fossa approach for VSs. In this retrospective, single-center cohort study evaluating the clinical outcomes after resection of small VSs using the middle fossa approach, consecutive adult patients (> 18 years) who underwent surgery between January 2000 and December 2021 were included. Clinical and imaging characteristics were analyzed, including baseline hearing status, duration of surgery, anesthetic parameters, and imaging characteristics of the surgically treated tumors. Among the 131 included patients, 102 had valid and discoverable pre- and postoperative audiology assessments. The mean follow-up was 26 months (range 1-180 months). There were 85 patients with serviceable hearing preoperatively, defined as American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) class A or B, of whom 78% retained class A or B hearing at the last follow-up. Binary logistic regression demonstrated that preoperative hearing AAO-HNS class (OR 0.19, 95% CI 0.05-0.77; p = 0.02), overlap between fundus and cochlea (OR 0.32, 95% CI 0.11-0.96; p = 0.04), and duration of anesthesia (OR 0.98, 95% CI 0.97-0.99; p = 0.03) were independent predictors of hearing outcomes. Additionally, 75% of patients with high diffusion-weighted imaging signal in the tumor (p = 0.009) and 67% of patients with the tumor originating at the modiolus of the cochlea (p = 0.004) had poor hearing outcomes. The hearing preservation rates after microsurgical resection of small VSs using the middle fossa approach are high, with 78% of patients maintaining AAO-HNS class A or B hearing. Poor hearing status at baseline, longer duration of anesthesia, and large overlap between the fundus of the internal auditory canal and the cochlea were independently associated with unfavorable hearing outcomes. Imaging characteristics can be used to stratify patients' risk of hearing loss.

Standardization of Outcome Measures for Intratympanic Steroid Treatment for Idiopathic Sudden Sensorineural Hearing Loss.

To identify variability in reported hearing outcomes for intratympanic (IT) steroid treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) by comparing outcomes using the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guideline with other published criteria. Retrospective chart review. Tertiary otology practice. Patients with ISSNHL treated with IT steroid between April 2003 and December 2020. IT steroid injection and audiometric evaluation. 1) Rates of full, partial, or no recovery using the AAO-HNS guideline versus other reported criteria, and 2) correlation analyses of demographic and clinical variables with response to IT steroid. Using AAO-HNS reporting criteria, full recovery of the pure-tone average was noted in 25.68% of patients. Applying eight other published outcomes criteria to this patient cohort classified full recovery in 14.87 to 40.54% of patients. Similarly, AAO-HNS criteria classified "no recovery" in 51.35% of our patients, whereas applying the other reported criteria showed an average rate of 62.16% no recovery and as high as 82.43% of patients without recovery. Younger age ( p = 0.003; effect size, 0.924) and IT injection within a week of onset ( p < 0.001; effect size, 1.099) positively correlated with full recovery. There was no impact of prior or concurrent oral steroids, or number of steroid injections on outcome. Great variability exists in the literature for assessment of IT steroid outcomes in ISSNHL. Standard reporting of outcomes as per the AAO-HNS SSNHL guideline is recommended to consistently characterize IT steroid efficacy and allow comparison across studies.

Correlation of clinical parameters with endolymphatic hydrops on MRI in Meniere's disease.

A clinical diagnosis of Ménière's disease (MD) is made based on medical history and audiometry findings. The 1995 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines requires histopathological confirmation of endolymphatic hydrops (EH) for a diagnosis of “certain” MD. Symptoms such as dizziness and ear fullness are important diagnostic features; however, the descriptions provided by patients are frequently vague and non-specific. A recently developed magnetic resonance imaging (MRI) protocol to document EH is, therefore, useful for the evaluation of inner ear status in patients with MD. In this study, patients with MD were assessed using MRI and the HYDROPS (HYbriD of Reversed image Of Positive endolymph signal and native image of positive perilymph Signal) protocol to investigate the effectiveness of MRI for visualization of the endolymphatic space in the diagnosis of MD by correlating clinical laboratory parameters with the grade of EH. Of the 123 patients with MD recruited in this study, 80 had definite MD, 11 had probable MD, and 32 had possible MD based on the 1995 AAO-HNS guidelines. The EH grade based on HYDROPS MRI was determined independently by two otorhinolaryngologists and compared with several clinical parameters, including the diagnostic scale of MD (1995 AAO-HNS guidelines), pure tone average (PTA), low tone average (LTA), canal paresis (CP) on the caloric test, and disease duration. Cochlear hydrops and vestibular hydrops were detected in 58 and 80% of 80 definite MD ears, in 33 and 58% of 12 probable MD ears, and in 5 and 27% of 37 possible MD ears, respectively. The proportion of higher hydrops grades increased significantly with grade according to the MD diagnostic scale (p < 0.0001). Both PTA and LTA were significantly higher in patients with hydrops grade 2 than hydrops grade 0 in both the cochlea and the vestibule. CP was significantly higher in patients with grade 2 than grade 0 vestibular hydrops. Disease duration was not associated with hydrops grade. Radiological evaluation of MD using the HYDROPS protocol is useful for evaluation of the extent and severity of EH in the diagnosis of MD based on its pathophysiological mechanism.

Risk factors for Meniere disease: a systematic review and meta-analysis.

To summarized the latest evidence of risk factors for developing MD. We searched Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, CBM, VIP, WanFANG, and CNKI, and ClinicalTrials.gov. till June 2021 for cohort and case-control studies investigating risk factors for MD. The exposure group was participants with a clinical diagnosis of MD which was made according to the diagnostic scale of the Equilibrium Committee of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS), the control group was participants without MD. The outcome was determined by incidence or prognostic of MD. Paired reviewers independently screened citations, assessed bias risk of included studies using the Newcastle-Ottawa Scale. Odds ratios (OR), hazard ratios(HR), relative risk(RR) and 95% confidence interval (CI) were calculated for dichotomous data. The statistical analyses were carried out with the use of Review Manager 5.3. The level of statistical heterogeneity for pooled data were assessed by using I2 statistics and Q-test. 768 abstracts and articles were identified by our search, of which 25 studies (n = 1, 471, 944) were included. There were 18 cohort studies, 7 case-control studies. Three distinct subgroups (age, sex, sleep) were identified. There were a total of two studies involving age, two studies involving gender and two studies involving sleep disorder. High to moderate methodological quality established that age [hazard ratios (HR) 2.21, 95% CI 1.85-2.65, I2 = 0%] and sleep disorder[HR 1.68, 95% CI 1.47-1.93, I2 = 0%] were risk factors for MD. While there was little evidence showing that sex was not a risk factor for MD [HR 1.61, 95% CI 0.91-2.84, I2 = 74%]. The current evidence supports the suggestion that age and sleep disorder are risk factors for MD. Sex, gene, and hypothyroidism are tentative risk factors but conflicting/inconclusive results.
