COVID-19 and otologic surgery.

In this article, we aim to summarize the impacts of COVID-19 on the practice of otologic surgery. Cadaveric studies have indicated COVID-19 viral particles are present in the middle ear mucosa of infected hosts. Otologic procedures can generate significant amounts of droplets due to reliance on high-speed drills. Multiple guidelines have been developed to improve patient and provider safety peri-operatively. Particle dispersion can be mitigated during microscopic mastoidectomy by utilizing barrier drape techniques. The barrier drape may similarly be applied to the surgical exoscope. Endoscopic techniques have theoretical improved safety benefits by minimizing the need for drilling. The discoveries and innovations borne of the COVID-19 pandemic will lay the groundwork for the practice of otology amidst future pandemics.

Better defining best-aided condition: The role of hearing aids on cochlear implantation qualification rates.

OBJECTIVE: Describe the effect of hearing aid type used during cochlear implantation evaluation on qualification rates. METHODS: Consecutive adult patients at an academic cochlear implant program undergoing cochlear implantation evaluation were identified to determine cochlear implantation qualification rate according to history of hearing aid use and type of hearing aid used during evaluation. RESULTS: 609 patients met criteria. 90.1% of patients reported prior use of a hearing aid, and 77.4% reported current use of a hearing aid. Patients were most likely to undergo cochlear implantation evaluation utilizing their own personal hearing aids exclusively (61.6%) followed by loaner hearing aids fitted at the time of the evaluation (28.2%). White patients were more likely to be tested using personal hearing aids (OR = 2.60, 95% CI 1.43 to 4.71). Married patients were more likely to be current hearing aid users (OR 1.62, 95% CI 1.04 to 2.51) and were more likely to be tested using personal hearing aids (OR = 1.68, 95% CI 1.10 to 2.56). Patients with a history of any hearing aid use (OR = 2.50, 95% CI 1.42 to 4.40) and current hearing aid use (OR = 1.62, 95% CI 1.06 to 2.49) were more likely to qualify for cochlear implantation. Patients tested using personal hearing aids were 1.5 times more likely to qualify for cochlear implantation (95% CI 0.99 to 2.27). CONCLUSION: History of hearing amplification and current amplification predict cochlear implant qualification. Hearing aids fitted at the time of cochlear implantation evaluation may result in lower qualification rates.

Rapidly Growing and Asymptomatic Skull Base Lesion.

Trochlear schwannomas typically present with diplopia and are extremely rare benign intracranial neoplasms that require the combined expertise of neurotologists and neurosurgeons for surgical excision. A combined petrosal approach offers a surgical route for removal of growing and/or symptomatic tumors. A study of a trochlear nerve schwannoma that demonstrated rapid growth but was otherwise asymptomatic was presented in this study.

Multiple cranial neuropathies following etanercept administration.

There have been recent reports of sarcoid-like granulomatosis development following the administration of tumor necrosis factor (TNF) inhibitors. To date, only four cases of neurosarcoidosis have been reported in association with TNF inhibitors, two of which were attributed to etanercept. We present the first case of etanercept-induced neurosarcoidosis involving multiple cranial neuropathies, including the trigeminal, facial, and vestibulocochlear nerves, while also highlighting the differential diagnoses of multiple cranial neuropathies and the association of TNF inhibitors and neurosarcoidosis.

Evaluating calcium channel blockers and bisphosphonates as otoprotective agents in cochlear implantation hearing preservation candidates.

OBJECTIVES: Evaluate potential effects of calcium channel blockers (CCB) and bisphosphonates (BP) on residual hearing following cochlear implantation. METHODS: Medications of 303 adult hearing preservation (HP) candidates (low frequency pure tone average [LFPTA] of 125, 250, and 500 Hz ≤80 dB HL) were reviewed. Postimplantation LFPTA of patients taking CCBs and BPs were compared to controls matched by age and preimplantation LFPTA. RESULTS: Twenty-six HP candidates were taking a CCB (N = 14) or bisphosphonate (N = 12) at implantation. Median follow-up was 1.37 years (range 0.22-4.64y). Among subjects with initial HP, 29% (N = 2 of 7) CCB users compared to 50% (N = 2 of 4) controls subsequently lost residual hearing 3-6 months later (OR = 0.40, 95% CI = 0.04-4.32, p = 0.58). None of the four BP patients with initial HP experienced delayed loss compared to 50% (N = 2 of 4) controls with initial HP (OR = 0.00, 95% CI = 0.00-1.95, P = 0.43). Two CCB and one BP patients improved to a LFPTA <80 dB HL following initial unaided thresholds that suggested loss of residual hearing. DISCUSSION: There were no significant differences in the odds of delayed loss of residual hearing with CCBs or BPs. CONCLUSION: Further investigation into potential otoprotective adjuvants for maintaining residual hearing following initial successful hearing preservation is warranted, with larger cohorts and additional CCB/BP agents.

Salvage Microsurgery Following Failed Primary Radiosurgery in Sporadic Vestibular Schwannoma.

Importance: Management of sporadic vestibular schwannoma with radiosurgery is becoming increasingly common globally; however, limited data currently characterize patient outcomes in the setting of microsurgical salvage for radiosurgical failure. Objective: To describe the clinical outcomes of salvage microsurgery following failed primary stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) among patients with sporadic vestibular schwannoma. Design, Setting, and Participants: This was a cohort study of adults (≥18 years old) with sporadic vestibular schwannoma who underwent salvage microsurgery following failed primary SRS/FSRT in 7 vestibular schwannoma treatment centers across the US and Norway. Data collection was performed between July 2022 and January 2023, with data analysis performed between January and July 2023. Exposure: Salvage microsurgical tumor resection. Main Outcomes and Measures: Composite outcome of undergoing less than gross total resection (GTR) or experiencing long-term facial paresis. Results: Among 126 patients, the median (IQR) age at time of salvage microsurgery was 62 (53-70) years, 69 (55%) were female, and 113 of 117 (97%) had tumors that extended into the cerebellopontine angle at time of salvage. Of 125 patients, 96 (76%) underwent primary gamma knife SRS, while 24 (19%) underwent linear accelerator-based SRS; the remaining patients underwent FSRT using other modalities. Postoperative cerebrospinal fluid leak was seen in 15 of 126 patients (12%), hydrocephalus in 8 (6%), symptomatic stroke in 7 (6%), and meningitis in 2 (2%). Each 1-mm increase in cerebellopontine angle tumor size was associated with a 13% increased likelihood of foregoing GTR (64 of 102 patients [63%]) or long-term postoperative House-Brackmann grade higher than I (48 of 102 patients [47%]) (odds ratio, 1.13; 95% CI, 1.04-1.23). Following salvage microsurgery, tumor growth-free survival rates at 1, 3, and 5 years were 97% (95% CI, 94%-100%), 93% (95% CI, 87%-99%), and 91% (95% CI, 84%-98%), respectively. Conclusions: In this cohort study, more than half of patients who received salvage microsurgery following primary SRS/FSRT underwent less than GTR or experienced some degree of facial paresis long term. These data suggest that the cumulative risk of developing facial paresis following primary SRS/FSRT by the end of the patient's journey with treatment approximates 2.5% to 7.5% when using published primary SRS/FSRT long-term tumor control rates.

"Do-It-Yourself" Ear Canal Care.

There are a large variety of over-the-counter home remedies and devices for cerumen impaction available in the United States. It is a challenge for clinicians to maintain awareness of the safety and efficacy of these tools, as they are not considered "medical devices" and frequently have no requirement for demonstrating safety or efficacy. This article provides a broad overview of the products being advertised to patients and discusses considerations when recommending home cerumen maintenance.

A Simulation of the Effect of Interview Caps on the National Resident Matching Program Match in Otolaryngology.

Concerns regarding interview hoarding in the Match process have led to calls for a cap on the number of interviews an applicant can accept. However, no study has examined the effects of interview caps on applicants or a specialty. The authors created a simulation otolaryngology Match to analyze the effects of interview caps. The simulation included 120 residency programs, 360 positions, and 570 applicants (each assigned a competitiveness weighted value). Programs created interview lists (subject to 4 different interview cap conditions: no, 16, 12, and 8 cap) using weighted random selection and the competitiveness weighted values. Programs then selected 3 interviewees to fill their positions via weighted random selection using the competitiveness weighted values. Data analysis explored the effects of interview caps on individual applicants' probability of matching, the probability of matching with a certain number of interviews, and the average matched applicant competitiveness rank using one-way analysis of variance. The introduction of interview caps caused interviews to be distributed more equally among applicants. The 12-interview cap caused the applicants in the 100th competitiveness percentile to see their probability of matching fall from 99.3% to 67.2% ( P < .001). Applicants with ≥ 12 interviews had a probability of matching of 94.4% when there was no cap, compared to 76.9% with a 12-interview cap ( P < .001). The average competitiveness rank of matched applicants fell from 191 with no cap to 245 with a 12-interview cap ( P < .001). Interview caps in the otolaryngology Match may create major distortions in the probability of matching, leading to much lower chances of matching for more competitive applicants, lower probabilities of matching with certain numbers of interviews, and a decreased average competitiveness of matched applicants.

The Influence of Activities and Functional Social Support on Adult Cochlear Implant Outcomes.

Objective: The objective of this study is to assess whether patient participation in specific activities and perceived social support correlate with speech perception following cochlear implantation. Setting: Tertiary referral hospital. Methods: Adult cochlear implantation patients implanted in their poorer hearing ear between January 2019 and December 2020 completed the Functional Social Support Questionnaire (FSSQ) and a modified version of the Victoria Lifestyle Study-Activities Lifestyle Questionnaire (VLS-ALQ). Demographics, FSSQ score, and individual activities were correlated with implanted ear and binaural AzBio scores. Results: Twenty-three patients completed the survey and had at least 6 months of follow-up with appropriate speech perception testing. The average age at survey completion was 71.7 (SD, 9.1). Average pure-tone average in the contralateral ear was 70.1 (SD: 20) dB. The majority (N = 21, 91.3%) wore a hearing aid in the contralateral ear following cochlear implantation. Mean AzBioQuiet score improvement was 60.6% (range: 20%-99%) in the implanted ear and 42.6% (range: -2% to 67%) binaurally. Work-related social support correlated positively with improvement in the implanted ear (Pearson's R = 0.473; 95% CI, 0.075-0.741; P = 0.023). Improvement in the implanted ear correlated positively with creative writing (R = 0.542; 95% CI, 0.167-0.780; P = 0.008), attending films (R = 0.448; 95% CI, 0.044-0.726; P = 0.032), going out with friends (R = 0.423; 95% CI, 0.013-0.711; P = 0.044) listening to audiobooks (R = 0.433; 95% CI, 0.025-0.717; P = 0.039), and public speaking (R = 0.468; 95% CI, 0.069-0.738; P = 0.024). Gains in binaural performance correlated positively with watching TV news (R = 0.819; 95% CI, 0.509-0.941; P < 0.001) and negatively with eating at restaurants (R = -0.532; 95% CI, -0.829 to -0.002; P = 0.05). Conclusions: Activities that provide intellectual stimulation and engage auditory faculties correlate with greater speech perception testing improvements in adult cochlear implantation patients.

Management of Complications in Vestibular Schwannoma Surgery.

Microsurgical removal of acoustic neuroma has advanced tremendously; however, complications still occur. Facial nerve injury is the most common detrimental complication and should take precedence over gross tumor removal in cases where there is an unfavorable tumor-facial nerve interface. Cerebrospinal fluid leakage can occur even with meticulous closure techniques and is generally treatable with either lumbar-subarachnoid drainage or revision wound closure. Meningitis is a serious complication that requires a high index of suspicion in the postoperative period. Other less common complications include intraoperative and postoperative vascular injuries. Early identification and treatment can prevent devastating outcomes.

Joint Vestibular Schwannoma Enlargement Prediction and Segmentation Using a Deep Multi-task Model.

OBJECTIVE: To develop a deep-learning-based multi-task (DMT) model for joint tumor enlargement prediction (TEP) and automatic tumor segmentation (TS) for vestibular schwannoma (VS) patients using their initial diagnostic contrast-enhanced T1-weighted (ceT1) magnetic resonance images (MRIs). METHODS: Initial ceT1 MRIs for VS patients meeting the inclusion/exclusion criteria of this study were retrospectively collected. VSs on the initial MRIs and their first follow-up scans were manually contoured. Tumor volume and enlargement ratio were measured based on expert contours. A DMT model was constructed for jointly TS and TEP. The manually segmented VS volume on the initial scan and the tumor enlargement label (≥20% volumetric growth) were used as the ground truth for training and evaluating the TS and TEP modules, respectively. RESULTS: We performed 5-fold cross-validation with the eligible patients (n = 103). Median segmentation dice coefficient, prediction sensitivity, specificity, accuracy, and area under the receiver operating characteristic curve (AUC) were measured and achieved the following values: 84.20%, 0.68, 0.78, 0.72, and 0.77, respectively. The segmentation result is significantly better than the separate TS network (dice coefficient of 83.13%, p = 0.03) and marginally lower than the state-of-the-art segmentation model nnU-Net (dice coefficient of 86.45%, p = 0.16). The TEP performance is significantly better than the single-task prediction model (AUC = 0.60, p = 0.01) and marginally better than a radiomics-based prediction model (AUC = 0.70, p = 0.17). CONCLUSION: The proposed DMT model is of higher learning efficiency and achieves promising performance on TEP and TS. The proposed technology has the potential to improve VS patient management.

Racial and Ethnic Disparities Among Hearing Aid and Cochlear Implant Patients at a Tertiary-Level Academic Otology Practice.

OBJECTIVE: Utilization of hearing aids (HAs) and cochlear implants (CIs) is limited, with our group previously demonstrating that non-White patients pursue CI less than White patients. The aim of this study was to compare the demographic makeup of patients more recently evaluated for both interventions in our clinic, exploring the influence of insurance on pursuit of HA, and whether changes have occurred in CI uptake. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary-level academic otology clinic. METHODS: All patients (18 yr or older) evaluated for an HA or CI in 2019 were included. Demographic variables (including race, insurance, and socioeconomic status) were compared between patients who did and did not obtain an HA or CI. RESULTS: In 2019, 390 patients underwent an HA evaluation, and 195 patients received a CI evaluation. Relative to patients evaluated for CI, patients evaluated for HA were more likely to be White (71.3% versus 79.4%, p = 0.027). Examining factors that affected HA purchase, Black race (odds ratio, 0.32; 95% confidence interval, 0.12-0.85; p = 0.022), and lower socioeconomic status (odds ratio, 0.99; 95% confidence interval, 0.98-1.00; p = 0.039) were associated with decreased odds. Demographic variables and AzBio quiet scores were not associated with decision to pursue CI surgery. CONCLUSIONS: White patients comprised a larger proportion of HA evaluations than CI evaluations. Furthermore, White patients and those of higher socioeconomic status were more likely to purchase HA. Improved outreach and expanded insurance benefits for HA are needed to ensure equal access to aural rehabilitation.

Audiometric and Patient-Reported Outcomes in Single-Sided Deafness Cochlear Implant Recipients Using the CIQOL-35.

OBJECTIVE: Describe the effect that cochlear implantation (CI) has on audiometric outcomes and quality of life (QOL) in patients with single-sided deafness (SSD). STUDY DESIGN: Retrospective case review. SETTING: Tertiary university hospital system. METHODS: Preoperative and postoperative AzBio performance and Cochlear Implant Quality of Life-35 (CIQOL-35) Profile scores in CI patients with SSD were compared, and postoperative measures were compared to those from CI patients without SSD. RESULTS: Seventeen patients with unilateral CI and contralateral unaided pure-tone averages ≤30 dB were included. The median age was 60.2 (interquartile range [IQR], 50.9-64.9 years), and 7/17 (41%) were women. Median daily use was 8.2 hour (IQR, 5.4-11.9 h). The median preoperative AzBio quiet score in the ear to be implanted was 3% (IQR, 0%-6%). After a median follow-up of 12.0 months, the median postoperative AzBio quiet score was 76% (IQR, 47%-86%) (p < .01). SSD subjects demonstrated statistically significant improvements in median scores on the following CIQOL-35 subdomains following implantation: Entertainment (17 preoperatively vs 21 postoperatively), Listening Effort (12 vs 14), Social (17 vs 22), and Global (28 vs 35; p < .05). SSD patients achieved equal or higher postoperative CIQOL-35 scores in most subdomains (6/7) compared to an age-matched group of non-SSD CI recipients who underwent unilaterally (N = 19) or sequential (N = 6) implantation. CONCLUSION: SSD CI patients not only demonstrate significant improvements in speech perception testing in the implanted ear but also exhibit improvement in multiple QOL subdomains on the CIQOL-35, the only validated cochlear implant QOL instrument.

Comparing Linear and Volumetric Tumor Measurements During Observation of Growing Sporadic Vestibular Schwannomas.

OBJECTIVE: To assess the correlation between linear and volumetric changes in vestibular schwannomas (VS). STUDY DESIGN: Retrospective imaging review was performed on patients diagnosed with sporadic VS from 2000 to 2019 who demonstrated linear growth on observation with serial magnetic resonance imaging (MRI). SETTING: Two large tertiary care centers. METHODS: Changes in diameter on serial MRI scans, measured by 1995 American Academy of Otolaryngology-Head and Neck Surgery guidelines, were compared to changes in volume, calculated by segmentation. RESULTS: Ninety-two patients had VS confined to the internal auditory canal (IAC) with 236 MRIs analyzed, and 108 patients had VS involving the cerebellopontine angle (CPA) with 193 MRIs analyzed. The Spearman rank correlation coefficients between changes in diameter and volume for IAC and CPA tumors were 0.43 (p < .001) and 0.65 (p < .001), respectively. Linear diameter increases of 1 to <2 mm corresponded to a median volume change of 32% (interquartile range [IQR]: 6%-86%) for IAC tumors, compared to 23% (IQR: 13%-40%) for CPA tumors. Linear diameter increases of 2 to <3 mm (ie, the minimum linear diameter change classically considered "true growth") corresponded to a median volume change of 42% (IQR: 23%-100%) and 47% (IQR: 26%-69%) for IAC and CPA tumors, respectively. CONCLUSION: Changes in linear diameter significantly correlated with changes in volume for IAC and CPA tumors, although diameter changes that did not meet the definition of linear growth (<2 mm) had corresponding median volume changes in excess of 20% for both IAC and CPA tumors.

Metformin Reduces Tumor Growth in a Murine Flank Schwannoma Model.

HYPOTHESIS: Metformin and aspirin reduce vestibular schwannoma (VS) growth. BACKGROUND: There have been reported associations between patients with VS prescribed metformin and decreased tumor volumetric growth. Aspirin has also been associated with decreased VS growth in animal studies. METHODS: Rat schwannoma cell lines were grown and implanted into 50 athymic nude mice. Tumors were grown to 5 mm, and then mice were injected with either low- or high-dose metformin, aspirin, or saline daily. Tumors were measured until 14 days elapsed or mice demonstrated symptoms such as ulceration, inability to walk, or passed away. RESULTS: There were no significant differences in day 0 tumor sizes between the control and the treatment groups ( p = 0.73). In the low-dose, but not high-dose groups, day 7 volumes were significantly different for both metformin ( p = 0.04) and aspirin ( p = 0.02) compared with placebo. Mean tumor growth rates were 126.6 ± 65.6 mm 3 /day for saline compared with 73.7 ± 29.5 mm 3 /day for low-dose metformin ( p = 0.03) and 68.7 ± 34.8 mm 3 /day for low-dose aspirin ( p = 0.016). There were no significant differences in tumor sizes ( p = 0.59) or growth rates ( p = 0.75) between low-dose metformin and aspirin groups. Low-dose groups had treatment stopped at 14 days, with continued monitoring demonstrating significant increases in tumor growth off treatment for both aspirin ( p = 0.006) and metformin ( p = 0.048). CONCLUSIONS: Metformin treatment significantly reduced VS growth to a similar level as aspirin. Furthermore, when removing both metformin and aspirin treatment, tumor growth significantly increased.

Stratifying Risk of Future Growth Among Sporadic Vestibular Schwannomas.

OBJECTIVE: In certain cases, clinicians may consider continued observation of a vestibular schwannoma after initial growth is detected. The aim of the current work was to determine if patients with growing sporadic vestibular schwannomas could be stratified by the likelihood of subsequent growth based on initial growth behavior. STUDY DESIGN: Slice-by-slice volumetric tumor measurements from 3,505 serial magnetic resonance imaging studies were analyzed from 952 consecutively treated patients. SETTING: Three tertiary-referral centers. PATIENTS: Adults with sporadic vestibular schwannoma. INTERVENTIONS: Wait-and-scan. MAIN OUTCOME MEASURES: Composite end point of subsequent growth- or treatment-free survival rates, where growth is defined as an additional increase of at least 20% in tumor volume from the volume at the time of initial growth. RESULTS: Among 405 patients who elected continued observation despite documented growth, stratification, of volumetric growth rate into less than 25% (reference: n = 107), 25 to less than 50% (hazard ratio [HR], 1.39; p = 0.06; n = 96), 50 to less than 100% (HR, 1.71; p = 0.002; n = 112), and at least 100% (HR, 2.01; p < 0.001; n = 90) change per year predicted the likelihood of future growth or treatment. Subsequent growth- or treatment-free survival rates (95% confidence interval) at year 5 after detection of initial growth were 31% (21-44%) for those with less than 25% growth per year, 18% (10-32%) for those with 25 to less than 50%, 15% (9-26%) for those with 50 to less than 100%, and 6% (2-16%) for those with at least 100%. Neither patient age ( p = 0.15) nor tumor volume at diagnosis ( p = 0.95) significantly differed across stratification groups. CONCLUSIONS: At the time of diagnosis, clinical features cannot consistently predict which tumors will ultimately display aggressive behavior. Stratification by volumetric growth rate at the time of initial growth results in a stepwise progression of increasing likelihood of subsequent growth. When considering continued observation after initial growth detection, almost 95% of patients who have tumors that double in volume between diagnosis and the first detection of growth demonstrate further tumor growth or undergo treatment if observed to 5 years.

Approach to Cochlear Implantation in Patients With Ventriculoperitoneal Shunts.

OBJECTIVE: To evaluate the safety and outcomes of cochlear implantation (CI) in patients with ventriculoperitoneal (VP) shunts to inform clinical practice. STUDY DESIGN: Historical cohort study. SETTING: Tertiary referral centers. METHODS: A multi-institutional historical cohort of patients with VP shunts and CI was identified and analyzed. RESULTS: A total of 46 patients (median age 8 years [interquratile range, IQR: 2-46]) with VP shunts and CI were identified. Of these, 41 (89%) patients had a VP shunt prior to CI. Based on institutional preference and individual patient factors, CI was performed contralateral to a pre-existing VP shunt in 24 of these 41 cases (59%) and ipsilateral in 17 (41%). Furthermore, pre-CI relocation of the VP shunt was performed in 3 cases (7%), and 2 patients (5%) underwent planned revision of their VP shunt concurrent with CI. In total, 2 of 27 pediatric patients (7%) required unanticipated revision shunt surgery, both contralateral to CI device placement, given VP shunt malfunction. One of 19 adult patients (5%) required shunt revision during CI due to shunt damage noted intraoperatively. Among 43 patients with available follow-up, 38 (88%) are regular CI users, with a median consonant-nucleus vowel-consonant word: score of 58% (IQR: 28-72). CONCLUSION: CI can be performed at low risk, either contralateral or ipsilateral, to a VP shunt, and does not mandate shunt revision in most cases. Additional considerations regarding CI receiver-stimulator placement are necessary with programmable shunts to mitigate device interaction. Preoperative planning, including coordination of care with neurosurgery, is important to achieving optimal outcomes.

Rationale for the Development of a Novel Clinical Grading Scale for Postoperative Facial Nerve Function: Results of a Multidisciplinary International Working Group.

OBJECTIVE: The objective of the current study was to present the results of an international working group survey identifying perceived limitations of existing facial nerve grading scales to inform the development of a novel grading scale for assessing early postoperative facial paralysis that incorporates regional scoring and is anchored in recovery prognosis and risk of associated complications. STUDY DESIGN: Survey. SETTING: A working group of 48 multidisciplinary clinicians with expertise in skull base, cerebellopontine angle, temporal bone, or parotid gland surgery. RESULTS: House-Brackmann grade is the most widely used system to assess facial nerve function among working group members (81%), although more than half (54%) agreed that the system they currently use does not adequately estimate the risk of associated complications, such as corneal injury, and confidence in interrater and intrarater reliability is generally low. Simplicity was ranked as the most important attribute of a novel postoperative facial nerve grading system to increase the likelihood of adoption, followed by reliability and accuracy. There was widespread consensus (91%) that the eye is the most critical facial region to focus on in the early postoperative setting. CONCLUSIONS: Members were invited to submit proposed grading systems in alignment with the objectives of the working group for subsequent validation. From these data, we plan to develop a simple, clinically anchored, and reproducible staging system with regional scoring for assessing early postoperative facial nerve function after surgery of the skull base, cerebellopontine angle, temporal bone, or parotid gland.

The purpose of this article is to outline the current state of evaluating children with unilateral hearing loss, with significant focus on cochlear implantation, in terms of reviewing the key points of the history, including the duration of deafness, outlining the recommended audiometric testing battery, and discussing issues related to imaging of the auditory system and related anatomy. In addition, a comprehensive and up-to-date summary of outcomes in terms of speech perception, sound localization, and quality of life for both the child with unilateral hearing loss as well as their parent(s) is reported.

Trends in Cochlear Implantation in Texas: An Exploration of Outpatient Discharge Data, 2010 to 2017.

OBJECTIVES: To describe trends in cochlear implantation (CI) disparities in Texas using an all-payer database from 2010 to 2017. METHODS: Texas Outpatient Surgical and Radiological Procedure Data, a public use data file, was accessed to analyze outpatient CI cases for Texas. Variables analyzed include patient age, sex, race/ethnicity, and insurance status. Population data from the American Community Survey generated CI utilization rates by patient demographic characteristics. RESULTS: There were 6158 CI cases identified during the study period. The number of CI per year nearly doubled from 497 in 2010 to 961 in 2017. The majority of CI recipients were white (59.5%), male (51.9%), and privately insured (47.9%). All sub-populations statewide had more CI in 2017 compared to 2010, with the overall CI per 100 000 population increasing from 1.98 to 3.50 per 100 000 population. Patients over 75 demonstrated the greatest increase in the CI rate per 100 000 population, increasing from 4.60 in 2010 to 14.30 in 2017. Regarding race/ethnicity, all sub-populations noted an increase in the CI per 100 000 population, with white patients demonstrating the highest rate in 2017, at 4.36 CI per 100 000 population. Asian patients had a 502% increase in the CI rate (from 0.42 to 2.53), compared with 87.9%, 84.4%, and 69.2% increases for white, Black, and Hispanic populations, respectively. CONCLUSIONS: CI became more widespread between 2010 and 2017, benefiting certain populations more than others. Black and Hispanic populations had lower CI per 100 000 population than their white peers, while patients >65 years of age accounted for the greatest increase in CI.
