Objective: To evaluate the associations between proxy measures of socioeconomic status (SES) and usage of cochlear implants. Study Design: Retrospective case series. Methods: Usage outcomes were measured among patients with a cochlear implant and data logging at a tertiary care children's hospital between 2002 and 2017. Time per day with cochlear implant turned on, coil off, and listening to speech in noise and speech in quiet were extracted from audiology records, averaging right and left ear usage for those with bilateral implants. Associations between cochlear implant usage and demographic factors such as insurance type and median household income for zip code were assessed. Results: There were 142 total patients; 74 had bilateral usage data. Mean on air time was 10.76 hours (SD: 4.4). Those with private insurance had 1.2 hour more on air time/day (P =.047) and 0.9 hour more quiet time/day (P =.011) compared to those with public insurance. Younger age at last visit was associated with increased speech in quiet (B = −.08; 95% CI: −0.12-[−0.05], P <.001) and coil off (B = −0.06; 95% CI: −0.11-[−0.02], P =.006). Younger age at implant was associated with longer duration since last data logging visit (B = −10.46; 95% CI: −18.41-[−2.51], P =.010), more daily use (on air; B = −0.23; 95% CI: −0.43-[−0.03], P =.026), and increased time spent listening to speech in noise (B = −0.07; 95% CI: −0.14-[−0.01], P =.024). No other significant associations between datalogging output and each proxy SES factor were found. Conclusions: Lack of private insurance and older age at implantation decreased access to binaural hearing for children and young adults with cochlear implants. [ABSTRACT FROM AUTHOR]

Objective: Evaluate health‐related quality of life (HR‐QOL) benefits with cochlear implantation (CI) in children with unilateral sensorineural hearing loss (USNHL) versus bilateral sensorineural hearing loss (BSNHL). Study Design: A cross‐sectional survey of parents of children who underwent CI for USNHL and BSNHL. Setting: Tertiary care academic centers. Methods: The "Children with cochlear implants: parental perspectives" survey was administered. Parents rated responses on a 5‐point Likert scale. Scores greater than 3.0 were considered favorable. Responses were recorded within 8 domains and groups were compared with respect to domain scores. Analysis of covariance models was used to compare groups while adjusting for age at implantation and duration of implant use. Results: There were 31 patients with USNHL and 27 patients with BSNHL. The average age of implantation in BSNHL patients was 1.9 and 6.7 years for USNHL. Parents of all children answered favorably in all domains. When adjusted for age at implantation and duration of implant use, parents of BSNHL children responded significantly more favorably only in 2 domains. When comparing patients with older age or prolonged duration of hearing loss in the USNHL cohort, there were favorable responses in all domains with no significant differences between groups. Conclusion: There are HR‐QOL benefits of CI in USNHL children; less pronounced favorable results were noted only in 2 domains when compared to BSNHL children. Benefits were noted with CI in USNHL children at an older age at implantation or prolonged duration of hearing loss. Therefore, these factors should not be absolute contraindications for CI in USNHL.

COVID-19 (COVID) delayed access to speech and hearing services. The objective of this study was to identify interactions between socioeconomic status (SES) and cochlear implant (CI) usage during COVID. Consecutive pediatric patients (age 0–17) with CI and audiology visits between 2019 and 2022 at a tertiary care children's hospital were reviewed. Age, sex, race, insurance type, and proxy measures for SES using zip code were recorded. Hours spent with CI on and in different listening environments were compared between pre-COVID (1/1/2019–12/31/2019), COVID (4/1/2020–3/31/2021), and most recent (6/1/2021–5/31/2022) time periods. Most patients were male (32/59, 54 % ears of 48 patients) and White, non-Hispanic (45/59, 76 %). Median age at implant was 2.0 years (range:0.6–12.2). There were no significant differences in hours spent with CI on during COVID compared with pre-COVID. However, children spent more time listening to louder noises (70–79 dB and ≥80 dB) recently compared with during COVID (p = 0.01 and 0.006, respectively). During COVID, children living in areas with greater educational attainment showed smaller reductions in total hours with CI on (β = 0.1, p = 0.02) and hours listening to speech in noise (β = 0.03, p = 0.005) compared with pre-COVID. In the most recent time period, children of minority race (β = −3.94 p = 0.008) and those who were older at implant (β = −0.630, p = 0.02) were more likely to experience reductions in total hours with CI on compared with during COVID. Interventions which mitigate barriers of implant use and promote rich listening home-environments for at risk populations should be implemented during challenging future social and environmental conditions.

Objective Routine plain film radiographs are often obtained to confirm proper placement of electrode after pediatric cochlear implant surgery. Objective is to evaluate necessity of routine radiographs in pediatric cochlear implant cases. Study design Retrospective review. Setting Two tertiary care academic centers. Subjects and methods Review of all children that underwent cochlear implantation from January 2003 thru June 2015. Exclusions include patients without intraoperative evoked compound action potential (ECAP) data or radiographs and patients undergoing revision surgeries. Results 235 pediatric patients underwent 371 cochlear implants. ECAP measurements were not available in two cases and were excluded from study. Radiographs were obtained in 35/369 cases due to intraoperative concern and four had abnormal findings. All four cases underwent change in management. One other patient had an x-ray because of difficult insertion and abnormal ECAP. Radiograph was normal; however, incision was opened and electrodes inserted further. Overall, 5/369 cases had changes in management intraoperatively. In all five cases, abnormalities were suspected by clinician judgment or abnormal ECAP measurements. Routine radiographs were completed in 349/369 cases and one was abnormal. This patient had known partial insertion due to cochlear fibrosis from meningitis and abnormal radiograph did not result in change in management. Conclusion Clinician suspicion and/or abnormal ECAP prompted suspicion for abnormal electrode placement prior to evaluation with radiograph in all cases in which change in management occurred. Intraoperative radiographs may be valuable in setting of clinical suspicion. Routine radiographs do not result in change in management and are, therefore, unnecessary. [ABSTRACT FROM AUTHOR]

Recent cochlear implant (CI) electrodes are designed to be atraumatic to inner ear structures. Studies in adults have demonstrated improved hearing preservation rates with the CI532/632 electrode, but none have examined this in children. Our objective is to describe the hearing preservation rate with CI532/632 in pediatric patients and determine factors that influence hearing preservation. We conducted a retrospective cohort study of children undergoing CI over a three-year period. Inclusion criteria were: CI with the 532/632 electrode, presence of pre-operative low frequency hearing defined by pure tone average (PTA) of ≤80 dB at 250 Hz or at the average of 250 and 500 Hz, and post-operative unaided audiometry. Other data collected included demographics, otologic history, imaging, and surgical details. A total of 13 patients and 15 ears were included. Hearing was preserved in 10/15 (66%) ears at an average follow-up of 6 months, similar to that reported in the adult literature. Patients with preserved hearing post-operatively were more likely to have a positive family history of hearing loss. There was a trend towards patients with anatomic inner ear abnormalities being more likely to lose hearing after CI, but this was not statistically significant. Pre-operative thresholds were not predictive of hearing preservation. Patients with preserved hearing had a significantly smaller shift in thresholds after cochlear implantation. Therefore, hearing preserved and non-preserved groups differed more by the magnitude of change in threshold, rather than their preoperative threshold. Other factors such as age, sex, surgeon, and surgery duration were not associated with hearing preservation. This study describes low frequency hearing preservation after pediatric CI532/632 implantation. The hearing preservation rate in our cohort was consistent with that reported in the adult literature. Our data suggest that preoperative thresholds do not solely determine which patients will go on to experience hearing preservation. We believe this will aid surgeons with patient-specific device selection and counseling potential pediatric CI recipients with preserved hearing. • Hearing preservation rate in this pediatric cohort was 66% with CI532/632. • Comparable to reports in adults with perimodiolar and lateral wall implants. • Anatomic inner ear abnormalities may confer higher risk of residual hearing loss. • Pre-operative thresholds are not strongly associated with hearing preservation.
