按常规方法行镫骨切除术的患者,大多数纯音测听骨气导差距消失,但要满意适应日常生活还差得远。言语辨别总是不好。镫骨切除术中切断镫骨肌键很可能引起上述情况。作者选择25例耳硬化症患者。男12例,女13例,年龄20～45岁,纯音测听气骨导差在30～50dB之间。听反射用220Hz探测音排除假阳性结果。言语辨别率 According to the conventional method of stapes resection of patients, most pure tone audiometry gap disappears, but to adapt to daily life still far. Speech recognition is always not good. Choroidctomy resection of the stapedius muscular key is likely to cause the above situation. The authors chose 25 patients with otosclerosis. There were 12 males and 13 females, aged from 20 to 45 years old. Pure tone audiometry was between 30 and 50 dB. Listen to reflections with 220Hz sounding test to eliminate false-positive results.
