Age Doesn't Affect Outcome of Revision Cochlear Implantation
Restoration in speech perception scores after revision cochlear implantation in younger, older cohorts
FRIDAY, Jan. 23, 2015 (HealthDay News) -- Age at revision cochlear implantation does not impact post-revision speech perception performance, according to research published online Jan. 22 in JAMA Otolaryngology-Head & Neck Surgery.
Margaret T. Dillon, Au.D., 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 percent before revision versus 47.7 and 47.6 percent, respectively, at three and six months after revision; for older cohort, mean CNC word test scores, 36.3 percent before revision versus 35.3 and 39.9 percent, 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.
