Objective Limited evidence to date has examined public perceptions of cochlear implants among adult hearing aid users with moderate to profound hearing loss. The current work was conceived with the chief objective of characterizing the perceptions surrounding cochlear implants among the prospective candidate pool. Study design National cross-sectional survey study. Setting United States. Patients Adults between 50 and 80 years of age with self-reported moderate to moderately severe (n = 200) or moderately severe to profound (n = 200) hearing loss currently using hearing aids. Results The overall survey response rate was 12%. Median age at time of survey for the 400 respondents was 66 years (interquartile range, 60–71 yr) and included 215 (54%) men. In total, 26% did not think of hearing loss as a medical condition, and another 23% were unsure. Overall, 63% of respondents had heard of cochlear implants, but only 2% indicated they were very familiar with them. Despite 52% of respondents reporting “very positive” or “somewhat positive” feelings about cochlear implants, only 9% indicated they were “very likely” to get a cochlear implant in the future, including 7% of those with estimated moderately severe to profound hearing loss at time of survey. Conclusions Even among people with presumed qualifying levels of hearing loss, there exists a widespread lack of familiarity with cochlear implantation as a viable treatment option. This limited awareness seems influenced by a generally poor appreciation for hearing loss as a chronic disease state that warrants treatment. However, among those familiar with cochlear implants, they are generally viewed favorably.

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.

Objective Hearing loss is increasingly recognized as a chronic disease state with important health sequelae. Although considered a central component of routine audiometric testing, the degree to which various patient factors influence speech discrimination is poorly characterized to date. The primary objective of the current work was to describe associations of cognitive performance, sociodemographic factors, and pure-tone audiometry with speech discrimination in older adults. Study Design Prospective study. Setting Olmsted County, Minnesota. Patients There were 1,061 study participants 50 years or older at enrollment in the population-based Mayo Clinic Study of Aging between November 2004 and December 2019 who underwent formal audiometric and cognitive testing included in the current investigation. Main Outcome Measures The primary outcome measure was word recognition scores (WRSs; measured as <100% vs 100% as well as continuous), with pure-tone averages (PTAs; 0.5, 1, 2, and 3 kHz), age, sex, years of education, state area deprivation index (ADI) quintiles, and global cognition z scores as explanatory features. Results The mean (SD) age among the 1,061 participants was 76 (9) years with 528 (50%) males. Participant age [OR (95% CI) for a 10-year increase of 1.8 (1.4–2.3), p < 0.001], male sex [OR = 2.6 (1.9–3.7), p < 0.001], and PTA [OR for a 10-dB hearing loss increase of 2.4 (2.1–2.8), p < 0.001] were all significantly associated with <100% WRSs, with the greatest explanatory ability attributable to the PTA. Years of education (p = 0.9), state ADI quintile (p = 0.6), and global cognitive performance (p = 0.2) were not associated with WRS. The multivariable model demonstrated strong predictive ability for less than perfect WRSs, with a c index of 0.854. Similar results were seen for WRSs analyzed as continuous, with the multivariable model resulting in an R 2 value of 0.433. Conclusions Although PTA exhibited the greatest influence on speech discrimination, advancing age and male sex both independently increased the likelihood of having worse speech discrimination among older adults, even after accounting for years of education, neighborhood-level socioeconomic disadvantage, and cognitive function. These findings help identify patient factors that can be instrumental when designing screening programs for adult-onset hearing loss.

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.

10.1097/mao.0000000000003932 | PMID 37367698

Objectives The current study characterizes age and incidence of cochlear implantation among qualifying children with congenital bilateral profound hearing loss in the U.S. Study Design Deidentified cochlear implantation data were acquired from prospectively collected patient registries from two cochlear implant (CI) manufacturers (Cochlear Americas and Advanced Bionics). Children <36 months old were assumed to have congenital bilateral profound sensorineural hearing loss. Setting U.S. CI centers. Patients Children <36 months old who received CIs. Interventions Cochlear implantation. Main Outcome Measures Age at implantation and incidence. Results A total of 4,236 children <36 months old underwent cochlear implantation from 2015 to 2019. The median age at implantation was 16 months (interquartile range, 12–24 mo) and did not change significantly during the 5-year study period (p = 0.09). Patients residing closer to CI centers (p = 0.03) and treated at higher-volume centers (p = 0.008) underwent implantation at a younger age. Bilateral simultaneous implantation increased from 38% to 53% of CI surgeries in 2015 and 2019, respectively. Children who received bilateral simultaneous CIs were younger compared with those receiving unilateral or bilateral sequential CIs (median, 14 versus 18 mo; p < 0.001). The incidence of cochlear implantation increased from 7,648 per 100,000 person-years in 2015 to 9,344 in 2019 (p < 0.001). Conclusion Although the incidence of pediatric CI recipients and the frequency of bilateral simultaneous implantation increased over the study period, age at implantation did not change significantly and far exceeded current Food and Drug Administration (9 mo) and American Academy of Otolaryngology and Head and Neck Surgery position statement (6–12 mo) guidelines.
Incidence of Cochlear Implantation Among Adult Candidates in the United States

10.1097/mao.0000000000003894 | PMID 37205861

Objectives To investigate the associations of age and year of cochlear implantation (CI) with CI incidence among adults 20 years and older residing in the US. Study Design Deidentified cochlear implant data were acquired from prospective patient registries from two cochlear implant manufacturers (Cochlear Americas and Advanced Bionics), which supply an estimated 85% of cochlear implants in the US. Population estimates for severe-to-profound sensorineural hearing loss by age group were extracted from Census and National Health and Nutrition Examination Survey data. Setting US CI centers. Patients Adults 20 years and older who underwent CI. Interventions CI. Main Outcome Measures CI incidence. Results The study cohort included 30,066 adults 20 years and older who underwent CI from 2015 to 2019. When combining actual and estimated data from all three manufacturers, the annual number of cochlear implants increased 5,406 in 2015 to 8,509 in 2019. Overall, the incidence of CI among adult traditional (bilateral severe-to-profound hearing loss) CI candidates increased from 244 per 100,000 person-years in 2015 to 350 in 2019 (p < 0.001). Although the elderly (80 years and older) population had the lowest incidence of CI, this cohort experienced the largest growth from an incidence of 105 per 100,000 person-years to 202 during the study period. Conclusions Despite growing incidence among those with qualifying hearing loss, cochlear implants remain widely underutilized. Elderly adults continue to exhibit the lowest relative cochlear implant utilization rates; however, trends over the last half-decade suggest a shift has occurred, resulting in improved access among this underserved subset.

AbstractObjectiveTo assess the correlation between linear and volumetric changes in vestibular schwannomas (VS).Study DesignRetrospective 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).SettingTwo large tertiary care centers.MethodsChanges 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.ResultsNinety‐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.ConclusionChanges 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.

Objective To characterize the effect of the COVID-19 pandemic on national cochlear implantation utilization by age using inclusive cochlear implantation data from two manufacturers between 2015 and 2020. Study Design Analysis of prospectively registered consecutive patient data from two major cochlear implant (CI) manufacturers in the United States. Patients Children or adults who received CIs. Interventions Cochlear implantation. Main Outcome Measures Annual implantation utilization by age. Results A total of 46,804 patients received CIs from the two participating manufacturers between 2015 and 2020. The annual number of implant recipients increased significantly during the first 5 years of the study period for both children and adults, from a total of 6,203 in 2015 to 9,213 in 2019 (p < 0.001). During 2020, there was a 13.1% drop in national cochlear implantation utilization across all ages compared with 2019, including a drop of 2.2% for those ≤3 years old, 3.8% for those 4–17 years old, 10.1% for those 18–64 years old, 16.6% for those 65–79 years old, and 22.5% for those ≥80 years old. In a multivariable linear regression model, the percent drop in CIs differed significantly by age-group (p = 0.005). Conclusions Especially in light of the prepandemic projected CI counts for 2020, the COVID-19 pandemic reduced national cochlear implantation utilization by over 15% among Medicare-aged patients and by almost 25% among those ≥80 years old, resulting in more than a 3-year setback in total annual CIs. Children were less affected, with those ≤3 years old experiencing minimal interruption during 2020.
Cochlear Implant Awareness in the United States: A National Survey of 15,138 Adults

AbstractHearing loss is increasingly recognized as a chronic disease that warrants treatment. Depression, social isolation, loneliness, and poorer cognitive performance have all been linked to untreated and undertreated adult-onset hearing loss. A significant subset of the patient population with hearing loss is inadequately rehabilitated by hearing aids alone and may benefit from cochlear implantation. Yet, it is estimated that less than 10% of those who qualify have received implants to date. A national survey was conducted online in November and December 2021. Subjects were identified using Dynata panelists and river sampling. Enrollment occurred on a rolling basis. Upfront sample management techniques were used to control the distribution, balancing the respondent cohort to the 2018 U.S. Census on age, household income, sex, marital status, household size, race/ethnicity, and education. Among 15,138 adult respondents with a mean (SD) age of 51 (17) years (54% female), only 10% reported being very familiar with cochlear implants, and 31% of those with hearing difficulty reported that they have “never heard” of a cochlear implant. Females were statistically significantly more likely to report some degree of familiarity with cochlear implants than men (34 vs. 26%; p < 0.01). The greatest familiarity with cochlear implants was observed among those aged 35 to 44 years (18% reporting “very familiar”), whereas only 9% of those aged 65 to 74, 10% aged 75 to 84, and 8% ≥85 reported being very familiar (p < 0.01). Those identifying as White/Caucasian were statistically significantly more likely to report familiarity with cochlear implants than those identifying as Black/African American and Hispanic/Latino/Spanish (33 vs. 56 vs. 50% responding that they had “never heard” of cochlear implants; p < 0.01). Among adults with hearing difficulty, nearly 80% report having never talked with a medical or hearing care professional about cochlear implants. Limited cochlear implant awareness likely influences its widespread underutilization across the United States. Sex, age, and race disparities compound these issues among men, the Medicare-aged population, and those identifying as Black/African American and Hispanic/Latino/Spanish.
