TABLE I.

Demographic characteristics of cochlear implanted participants. Note: P = participant. Chronological age in years, age at CI in months (for participants 1–9) or years (for participants 10–19). Participants 1–4, 6–9, and 13 were bilaterally implanted. * Age at CI in months for children and in years for adults. Ear tested was always better hearing ear or right ear if symmetrical. CM = communication mode. TC = total communication (Signed Exact English plus oral). Bil = oral plus American sign language. NS = genetic identified nonsyndromic. VS = post vestibular schwannoma resection. Genetic = hereditary, not specified.
