Résumé

Objective To investigate the hearing performance of adult patients presenting unilateral deafness with contralateral fluctuating hearing loss who received a cochlear implant on the deaf side. Study Design Case series with chart review. Setting University tertiary referral center. Subjects and Methods Preoperatively and at 6 and 12 months postoperatively, 23 patients underwent pure tone audiometry and speech audiometry with disyllabic and monosyllabic words in a quiet environment and sentences in quiet and noisy (signal-to-noise ratio +10 dB SPL) environments under best-aided conditions. The Abbreviated Profile of Hearing Aid Benefit (APHAB) inventory was evaluated preoperatively and at 6 and 12 months postoperatively. Results No difference was found between pre- and postoperative tests for disyllabic and monosyllabic words. For sentences in quiet and noisy environments, a difference between pre- and postoperative performance was present at 1 year ( P = .002 and P = .02, respectively). In a noisy environment, a difference was present at 6 and 12 months postoperatively as compared with the preoperative value (mean ± SD: 6 months: 42% ± 7.1% vs 61% ± 6.5%, P = .016). A significant improvement in the APHAB score was found at 6 and 12 months postimplantation (Friedman’s 2-way analysis of variance by ranks, P < .001). The number of years of hearing deprivation of the deaf ear was not correlated with performance. Conclusion When incapacitating fluctuating hearing loss occurs in patients presenting a contralateral deaf ear, a cochlear implant is indicated in the latter ear, significantly improving performance in noisy conditions and allowing a better quality of communication to be achieved.
