The aims of this study were to evaluate the hearing outcomes 28 to 30 years after stapedectomy in patients with surgically confirmed otosclerosis, and to evaluate inner ear involvement.
A retrospective clinical study was performed. Sixty-five consecutive patients who underwent stapedectomy at a tertiary referral center between 1977 and 1979 were included in the study. Medical records, including preoperative and postoperative audiograms, were reviewed, and a long-term follow-up clinical examination and pure tone audiometry were performed. The hearing outcome was compared with that of a reference population (ISO 7029) in terms of age and gender.
Thirty years after stapedectomy, 66% of the patients' ears studied showed a moderate to profound hearing loss. The deterioration was mainly caused by a sensory hearing loss. The hearing loss was significantly greater than that in the reference population for both air and bone conduction thresholds at the early and late stages of the disease. A large majority of the patients (88%) had bilateral otosclerosis.
Patients with otosclerosis have a sensorineural hearing loss that cannot be explained by age. Otosclerosis should be regarded as a middle and inner ear disease. Almost all patients with otosclerosis are in need of ongoing audiological rehabilitation and hearing aids.
本研究旨在评估手术确诊耳硬化症患者镫骨切除术后28至30年的听力结果，并评估内耳受累情况。
进行了一项回顾性临床研究。研究纳入了1977年至1979年间在一家三级转诊中心连续接受镫骨切除术的65例患者。查阅了包括术前和术后听力图在内的病历，并进行了长期随访临床检查和纯音听力测定。根据年龄和性别，将听力结果与参考人群（ISO 7029）进行比较。
镫骨切除术后30年，所研究患者的66%耳显示中度至重度听力损失。听力下降主要由感音性听力损失引起。在疾病的早期和晚期，气导和骨导阈值的听力损失均显著大于参考人群。绝大多数患者（88%）患有双侧耳硬化症。
耳硬化症患者存在无法用年龄解释的感音神经性听力损失。耳硬化症应被视为中耳和内耳疾病。几乎所有耳硬化症患者都需要持续的听力学康复和助听器。
