Coronavirus Disease-19 and Otology/Neurotology.

The severe acute respiratory syndrome corona virus 2, responsible for the worldwide COVID-19 pandemic, has caused unprecedented changes to society as we know it. The effects have been particularly palpable in the practice of medicine. The field of otolaryngology has not been spared. We have had to significantly alter the way we provide care to patients, changes that are likely to become a new norm for the foreseeable future. This article highlights some of the changes as they apply to otology/neurotology. Although this is written from the perspective of an academic physician, it is also applicable to private practice colleagues.

Trends in Intraoperative Testing During Cochlear Implantation.

OBJECTIVE: No consensus guidelines exist regarding intraoperative testing during cochlear implantation and wide variation in practice habits exists. The objective of this observational study was to survey otologists/neurotologists to understand practice habits and overall opinion of usefulness of intraoperative testing. STUDY DESIGN: Cross-sectional survey. SETTING: A web-based survey was sent to 194 practicing Otologists/Neurotologists. MAIN OUTCOME MEASURES: Questions included practice setting and experience, habits with respect to electrodes used, intraoperative testing modalities used, overall opinion of intraoperative testing, and practice habits in various scenarios. RESULTS: Thirty-nine of 194 (20%) completed the survey. For routine patients, ECAPs and EIs were most commonly used together (38%) while 33% do not perform testing at all. Eighty-nine percent note that testing "rarely" or "never" changes management. Fifty-one percent marked the most important reason for testing is the reassurance provided to the family and/or the surgeon. CONCLUSION: Intraoperative testing habits and opinions regarding testing during cochlear implantation vary widely among otologic surgeons. The majority of surgeons use testing but many think there is minimal benefit and that surgical decision-making is rarely impacted. The importance of testing may change as electrodes continue to evolve.

Survey of the American Neurotology Society on Cochlear Implantation: Part 2, Surgical and Device-Related Practice Patterns.

OBJECTIVE: To examine surgical and device-related cochlear implant practice patterns across centers in the United States. METHODS: Cross-sectional survey of the American Neurotology Society (ANS). RESULTS: A total of 81 surveys were returned from ANS members who report regular involvement in cochlear implant care. Overall there was a broad distribution in age and clinical experience, with most respondents reporting Accreditation Council for Graduate Medical Education (ACGME) accreditation in neurotology and employment at an academic center. The annual volume of cochlear implant surgeries varied considerably across centers. Eighty percent of respondents report to offer all three Food and Drug Administration (FDA) approved device brands at their center.In cases where hearing preservation is not a goal, 56% of respondents prefer a perimodiolar electrode design, while 44% prefer a lateral wall electrode. With regard to insertion technique for scala tympani access, 64% prefer inserting through the round window (RW) membrane, 26% prefer an extended round window (ERW) approach, while only 10% prefer a cochleostomy. In cases where hearing preservation is a goal of surgery, 86% of respondents prefer a lateral wall electrode design, while only 14% prefer a perimodiolar electrode design. With regard to insertion technique, 86% prefer RW insertion, while only 9% prefer an ERW approach, and only 5% prefer a cochleostomy. Respondents who prefer RW electrode insertion more commonly use a lateral wall electrode, whereas those who prefer an ERW or cochleostomy approach more commonly use a periomodiolar electrode (p < 0.001). There was a statistically significant greater number of surgeons that prefer lateral wall electrodes (p < 0.001) and RW insertion (p < 0.001) for hearing preservation cases compared with non-hearing preservation cases. For implantation of a hypothetical patient with significant residual hearing, within the range of hybrid device candidacy, the great majority of surgeons prefer a conventional length electrode and only 29% prefer to implant a hybrid device.In cases where hearing preservation is a goal, the overwhelming majority of respondents (96%, n = 74) reported using at least one form of steroid application. Ninety-two percent (n = 71) used intraoperative intravenous steroids, 55% (n = 42) prescribed postoperative oral steroids, 44% (n = 34) bathed the middle ear with steroids during surgery, and 30% (n = 23) prescribed preoperative oral steroids.Together, 65% of respondents use a variation of the tight subperiosteal pocket technique for internal device fixation, 19% prefer a bony well and trough with tie-downs, 10% prefer a bony well and trough without tie-downs, and 5% prefer a screw fixation system. Of the 50 who prefer utilizing a subperiosteal pocket, 31 (62%) incorporate a bony trough and 19 (38%) perform a subperiosteal pocket alone without a bony trough. CONCLUSION: The results of this survey reflect the evolution in surgical and device-related preferences for cochlear implantation in the United States. An increasing number of surgeons prefer the RW approach for electrode insertion. When hearing preservation is not a goal, there is a near even preference for lateral wall and perimodiolar electrode designs; however, the great majority of surgeons prefer a lateral wall design when attempting to preserve residual acoustic hearing. Even in cases where substantial residual hearing exists, many surgeons prefer conventional length electrodes to hybrid designs. These changes reflect the prioritization of atraumatic surgery and parallel the development of thinner and more atraumatic electrodes.

Survey of the American Neurotology Society on Cochlear Implantation: Part 1, Candidacy Assessment and Expanding Indications.

OBJECTIVE: To examine practice variance of cochlear implant candidacy assessment and off-label indications across centers in the United States. METHODS: Cross-sectional survey of the American Neurotology Society (ANS). RESULTS: A total of 81 surveys were returned from ANS members who report regular involvement in cochlear implant care. Overall there was a broad distribution in age and clinical experience, with most respondents reporting ACGME accreditation in neurotology and employment at an academic center. The annual volume of cochlear implant surgeries varied considerably across centers.Seventy-eight percent of respondents performed cochlear implantation for at least one of the following indications within the last 2 years: profound hearing loss in children less than 12 months of age (35, 43%), children with asymmetrical hearing loss where at least one ear was better than performance cutoff for age (25, 31%), adults with asymmetrical hearing where at least one ear was better than the performance cutoff for adult criteria (49, 61%), single-sided deafness (37, 46%), and ipsilateral vestibular schwannoma (28, 35%). Centers with a higher annual implant volume more frequently performed off-label implantation in all queried populations (all, p≤0.001), and performed surgery on infants with congenital deafness at a younger age (p = 0.013), compared with centers with lower surgical volume.When surveyed regarding speech perception testing practices for adult candidacy assessment, 75 (100%) respondents who answered this question reported routine use of AzBio sentences, 42 (56%) CNC word scores, and 26 (35%) HINT testing; only 7 (9%) reported using BKB-SIN testing and 6 (8%) reported using CUNY scores. Fifty-one (68%) reported routine use of speech-in-noise testing to determine adult cochlear implant candidacy, 21 (28%) reported selective use only when patient scores were borderline in quiet, and 3 (4%) reported that their center does not currently use testing in noise for candidacy determination. Nineteen (26%) solely used +10 dB signal-to-noise ratio (SNR), 12 (16%) solely used +5 dB SNR, and 41 (55%) used both +10 and +5 dB SNR. Overall, 19% (N = 14) only perform unilateral implantation in the Medicare population, while 81% (N = 58) consider bilateral implantation. CONCLUSION: Significant variation in cochlear implant candidacy assessment and off-label implantation exists across centers and providers in the United States resulting in healthcare inequities. The high percentage of surgeons performing implantations for off-label or nontraditional indications reflects the overly restrictive and dated status of current implant guidelines. With greater adoption of more difficult speech perception testing in noise, careful clinical judgment is needed to maintain a favorable risk-benefit balance for prospective implant candidates.

Epidemiology of Dizzy Patient Population in a Neurotology Clinic and Predictors of Peripheral Etiology.

OBJECTIVE: To compare the proportion of peripheral versus nonperipheral dizziness etiologies among all patients, inclusive of those presenting primarily or as referrals, to rank diagnoses in order of frequency, to determine whether or not age and sex predict diagnosis, and to determine which subgroups tended to undergo formal vestibular testing. STUDY DESIGN: Retrospective cohort. SETTING: Academic neurotology clinic. PATIENTS: Age greater than 18 neurotology clinic patients with the chief complaint of dizziness. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Age, sex, diagnosis, record of vestibular testing. RESULTS: Two thousand seventy-nine patients were assigned 2,468 diagnoses, of which 57.7 and 42.3% were of peripheral and nonperipheral etiologies, respectively. The most common diagnoses were Ménière's (23.0%), vestibular migraine (19.3%), benign paroxysmal positional vertigo (BPPV) (19.1%), and central origin, nonmigraine (16.4%). Peripheral diagnoses are more likely to be found in men than in women (odds ratio [OR] 1.59). Peripheral diagnoses were most likely to be found in the 60 to 69 age group (OR 3.82). There was not a significant difference in rate of vestibular testing between women and men. Among patients with two diagnoses, the most common combinations were vestibular migraine and BPPV then vestibular migraine and Ménière's. CONCLUSIONS: A large proportion of patients seen for the chief complaint of dizziness in the neurotology clinic were found not to have a peripheral etiology of their symptoms. These data challenge a prevalent dogma that the most common causes of dizziness are peripheral: BPPV, vestibular neuritis, and Ménière's disease. Age and sex are statistically significant predictors of peripheral etiology of dizziness.

[Pre- and posttreatment results of an inpatient neurotologic and psychosomatic tinnitus therapy]. / Prä- und Post-Ergebnisse einer stationären neurootologisch fundierten und psychosomatischen Tinnitustherapie.

BACKGROUND: Inpatient treatment of chronic complex tinnitus can be necessary for patients with a high symptomatic strain, mostly accompanied by a corresponding mental comorbidity, and/or for patients that can only perceive their psychogenic suffering through somatization into tinnitus. METHODS: We report the results of 368 consecutively treated inpatients with chronic complex tinnitus. Patients' audiometric data were collected, and at the beginning and end of treatment, the Mini-Tinnitus Questionnaire (Mini-TQ12; Hiller und Goebel) was completed, as was the German version of the Hospitality Anxiety and Depression Score (HADS). Effect sizes were calculated for both questionnaires. Mean treatment duration was 38.8 days (standard deviation, SD: 13.6 days). The main therapeutic elements were intensive disorder-specific neurotologic counselling and psychoeducation; improvement of hearing by fitting of hearing aids, complemented by an individualized hearing therapy; and intensive individual and group-based psychotherapy. RESULTS: In addition to tinnitus, 82.1% of the patients had reduced hearing requiring rehabilitation with hearing aids. After hospitalization, a highly significant improvement in tinnitus strain could be demonstrated by the Mini-TQ12. Furthermore, a significant reduction in the depression and anxiety components of HADS was also achieved, with high effect sizes of 1.6 to 2.2. No reduction of tinnitus symptoms to a medium- or low-range level was experienced by 8.9% of patients. CONCLUSION: With corresponding symptomatic suffering, disorder-specific inpatient tinnitus treatment comprising neurotologic and psychosomatic alignment can achieve medium- to high-range therapeutic effects.

Survey on the state of otoneurology in Spain.

Otoneurology is a subspecialty of otolaryngology-neurology, which has experienced extraordinary progress in the last 50 years and is currently fully consolidated in our environment. Through this study, prepared by the Otoneurology Commission of the Spanish Society of Otorhinolaryngology (SEORL), we have attempted to design an approach to provide information on what the current situation regarding the exercise in Spain is, trying to determine who practice it and where, what resources are available and what the teaching and scientific productions are. The results obtained are generally satisfactory and reflect the strength of the exercise of otoneurology. The number of centres with otoneurology units is significant and the majority of centres that lack such a unity consider it necessary. However, there are aspects to establish related to minimum requirements for its performance in satisfactory conditions, as well as determining future guidelines to ensure improved teaching and increased scientific production.
