著者报告1例女性患者,因耳硬化症行左侧镫骨切除术,术后听力明显改进,三个月后常规电测听检查,在检查右耳骨传导时测听人员给已切除镫骨的左耳用强噪声掩蔽,测听后患者发现左耳听力又恢复术前状态,术后获得改进的那一部分听力完全丧失。著者认为这是由于镫骨切除术后不能经受强声刺激之故,否则即引起内耳损伤,甚至产生永久性感音性全聋。 The authors report a female patient who underwent left ostomy for otosclerosis. Hearing was significantly improved after surgery. Three months later routine electrical audiometry was performed. In the examination of the right ear bone conduction, the audiologist gave the resected stapes Of the left ear with strong noise masking, audiometry found that patients with left ear hearing and return to preoperative state, improved after that part of the hearing loss completely. The authors believe that this is due to the stomatognomy can not withstand the strong sound stimulation, or cause damage to the inner ear, and even have a permanent sensorineural deafness.
