Objectives/Hypothesis To describe the pre‐implant audiometric profile of adult cochlear implant (CI) recipients to investigate whether current binaural candidacy requirements prevent access to patients who could benefit from CI. Study Design Retrospective case series. Methods Retrospective review from 2016 to 2018 evaluating preoperative pure‐tone thresholds and speech perception scores in the ipsilateral and contralateral ear. Results A total of 252 adult CI recipients undergoing 270 implants were identified. Median age at time of implantation was 70.5 years (IQR 61.3–78.3) for those undergoing unilateral implantation and 59.0 (IQR 48.0–72.3) for those undergoing bilateral implantation ( P < .01). For unilateral implantation, median pre‐implantation speech perception performance in the ear to be implanted was 8.0% (IQR 0%–26.0%) for CNC word scores, and 9.0% (IQR 0%–34.0%) for AzBio sentence scores in quiet. Median speech perception performance in the contralateral ear was 36.0% (IQR 14.0%–60.0%) on CNC word scores, and 48.5% (IQR 17.5%–76.0%) on AzBio sentence tests. Speech perception scores were significantly different between ears for word and sentence tests ( P < .01). Patients older than age 65 were significantly less likely to undergo bilateral implantation ( P = .03). Conclusions Adult CI recipients exhibit substantially poorer pre‐implant speech perception scores than the commonly utilized ipsilateral qualifying threshold of 50% on sentence testing. Yet, existing insurance paradigms limit patients by excessively stringent binaural best‐aided requirements. This limitation likely leads to worse device performance as patients often wait years for their binaural hearing to qualify while their ear to be implanted potentially experiences an unnecessarily extended duration of deafness. Older patients also experience a unique delay in referral for cochlear implantation. Level of Evidence 3‐ Retrospective review Laryngoscope , 131:E2007–E2012, 2021

Précis: Kaplan-Meier analysis was used to compare the rate of corneal grafting after glaucoma drainage device (GDD) placement in pediatric and adult patients. Adults were at an increased risk of receiving a corneal graft after device placement. Purpose: The goal of this study was to compare the rate of corneal graft implantation after GDD placement in pediatric and adult patients. Patients: Patients receiving a GDD between January 1, 1985 and December 31, 2017 were selected from the medical records. Patients receiving their first device while <18 years of age were considered children for the extent of the study. Methods: We compared the rate of receiving a corneal graft after GDD implantation using Kaplan-Meier analysis. Baseline patient characteristics and surgical characteristics were compared using a generalized estimating equation. Results: Corneal grafting occurred in 8.6% of adults and 4.7% of children from the original cohort. The rate of receiving a corneal graft at 5, 10, and 15 years was 9.4%, 16.8%, 39.4% and 1.6%, 1.6%, 12.5% for adults and children, respectively. However, certain characteristics were different between the 2 groups. Conclusion: Adult patients were more likely to receive a corneal graft after GDD placement. However, pediatric and adult patients differed in the prevalence of preexisting corneal disease, glaucoma type, GDD type used, and types of previous surgeries. Elucidation of the impact of these factors on corneal graft rate requires a larger cohort size.
