Abstract

Objective: This study aims to evaluate the long-term auditory performance at 5 years in patients with far advanced otosclerosis (FAO) after cochlear implantation compared to controls.

Study design: A retrospective cohort study.

Setting: This study was conducted at a single tertiary medical center.

Methods: Patients with FAO were compared to a control group of postlingually deafened patients, selected from the same cochlear implant database. The following data were collected from medical records: age, sex, etiology, duration of hearing deprivation, prior stapes surgery, age at implantation, side of implantation, computed tomography scan findings, surgery details, postoperative complications, and hearing test results.

Results: A total of 41 patients with otosclerosis and 73 control cases were included in this study. The mean speech comprehension score at 5 years was 48.63% ± 24.66 in the otosclerosis group compared to 48.17% ± 23.08 in the control group (P = .76). Cochleostomy (P = .01), scala vestibuli insertion (P < .001), and postoperative dizziness (P < .01) were more common in the otosclerosis group. Facial nerve stimulation was observed in both groups: otosclerosis group 4 cases (9.8%) and control group 4 cases (5.48%) (P = .39). In the otosclerosis group, at 5 years, the average speech comprehension in patients with a previous stapedotomy was 39.3% ± 23.9 and 57.52% ± 22.45 in patients without a previous stapedotomy (P = .02).

Conclusion: Cochlear-implanted patients with otosclerosis achieve satisfactory long-term audiometric outcomes, although with higher surgical challenges and complication rates compared to other etiologies. Notably, we found that a history of stapedotomy can negatively impact long-term auditory outcomes after cochlear implantation.

期刊介绍： Otolaryngology–Head and Neck Surgery (OTO-HNS) is the official peer-reviewed publication of the American Academy of Otolaryngology–Head and Neck Surgery Foundation. The mission of Otolaryngology–Head and Neck Surgery is to publish contemporary, ethical, clinically relevant information in otolaryngology, head and neck surgery (ear, nose, throat, head, and neck disorders) that can be used by otolaryngologists, clinicians, scientists, and specialists to improve patient care and public health.
