目的:了解耳硬化症的听力特点及纯音测听的诊断作用。方法:选择24例病程1~25年、声导抗及纯音测听结果符合耳硬化症病变特征的患者,其中少数民族患者12例,汉族患者12例。应用纯音测听仪检测听力水平。结果:24例耳硬化症患者听力损害程度均为B~E级。少数民族患者的病程均超过5年,听力损害程度均为C级以上。所有患者均有较明显的气骨导间距,盖莱试验均为阴性,均有Carhart切迹。4例患者合并感音神经性耳聋。结论:耳硬化症患者的听力损失程度与发病年限有关,且少数民族患者听力受损程度较汉族患者重。
Objective: To understand the hearing characteristics of ear sclerosis and the diagnostic role of pure tone audiometry. Methods: Twenty-four patients with duration of 1 to 25 years and acoustic impedance and pure tone audiometry conforming to the pathological features of otosclerosis were selected. Among them, 12 were minority patients and 12 were Han patients. Apply a pure tone audiometer to detect hearing levels. Results: All 24 patients with otosclerosis had grade B ~ E of hearing impairment. Minority patients with more than 5 years of disease duration, hearing impairment are more than C-level. All patients had a more obvious air-bone spacing, Geller test were negative, all with Carhart notch. 4 patients with sensorineural deafness. Conclusion: The degree of hearing loss in patients with otosclerosis is related to the age of onset, and minority patients have more hearing loss than Han patients.
