Age's Effect on Outcome of Revision Cochlear Implantation Assessed
(HealthDay News) — Age at revision cochlear implantation does not impact post-revision speech perception performance, according to research published online January 22 in JAMA Otolaryngology-Head & Neck Surgery.
Margaret T. Dillon, AuD, from the University of North Carolina at Chapel Hill, and colleagues conducted a retrospective analysis to examine whether age at revision cochlear implantation correlates with post-revision speech perception performance. Participants included 14 younger adults (<65 years) and 15 older adults (≥65 years).
The researchers observed a restoration in speech perception scores after revision cochlear implantation compared with the best performance before revision in both cohorts (for younger cohort, mean consonant-nucleus-consonant [CNC] word test scores, 43.9% before revision vs. 47.7 and 47.6%, respectively, at three and six months after revision; for older cohort, mean CNC word test scores, 36.3% before revision vs. 35.3 and 39.9%, respectively, at three and six months after revision; P=0.40). No interaction was seen between age at revision surgery and speech perception performance at each assessment interval (P=0.60).
"Advanced age should not be considered a contraindication to revision cochlear implantation," the authors write.
