Individual differences in speech recognition changes after cochlear implantation
JAMA Otolaryngology—Head & Neck Surgery Jan 11, 2021
Dornhoffer JR, Reddy P, Meyer TA, et al. - Using a prospectively maintained database, researchers conducted this cross-sectional study to evaluate changes in preoperative aided vs postoperative speech recognition scores for individual patients receiving cochlear implants when considering the measurement error for each speech recognition test. The sample consisted of patients who received cochlear implants between January 1, 2012, and December 31, 2017, at a tertiary, university-based referral center. In this cross-sectional study, postoperative cochlear implant outcomes for individual patients were largely encouraging with respect to preoperative aided speech recognition. Improvements in scores for individual patients, however, remained highly variable, which may not be sufficiently reflected in groupwise analyses and mean scores reporting. Presenting individual patient data from a large sample of individuals with cochlear implants offers a greater explanation of individual variations in speech recognition outcomes and leads to a more complete interpretation of good outcomes following cochlear implantation.
