Abstract

IMPORTANCE: This study reviewed whether advanced age should be a consideration when revision cochlear implantation is warranted. OBJECTIVE: To examine whether age at revision cochlear implantation is related to postrevision speech perception performance. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysiswas performed in an academic tertiary care center. Participants included 14 younger adults (<65 years) and 15 older adults (≥65 years) who underwent revision cochlear implantation. INTERVENTION: Revision cochlear implantation. MAIN OUTCOMES AND MEASURES: Speech perception performance, as measured with consonant-nucleus-consonant [CNC] words in quiet, at the best prerevision interval as well as the 3- and 6-month postrevision intervals were compared between the 2 cohorts. The CNC word test consists of 10 lists of 50 phonemically balanced monosyllabic words, scored with a range of 0%to 100% correct. RESULTS: Both cohorts experienced a restoration in speech perception scores after revision cochlear implantation compared with their best performance before the revision (mean [SD] CNC word test scores for the younger cohort: 43.9%[25.6%] before revision and 47.7% [21.3%] at 3 months and 47.6%[19.8%] at 6 months after revision; for the older cohort: 36.3%[19.1%] before revision and 35.3%[17.2%] at 3 months and 39.9%[16.3%] at 6 months after revision; F2,54 = 0.93; P = .40). There was no interaction between age at revision surgery and speech perception performance at each assessment interval (F2,54 = 0.51; P = .60). CONCLUSIONS AND RELEVANCE: In this study, age at revision cochlear implantation was not related to postrevision speech perception performance. Advanced age should not be considered a contraindication to revision cochlear implantation.
