目的:探讨开放式鼓室成型手术含Ⅰ期听骨链重建患者术后听力情况及导致术后听力不提高的原因。方法:总结我科2005-03/2007-07的32例患者鼓室成型Ⅰ期听骨链重建术后听力恢复情况。结果:术后随访2~3 a,所有患者皆干耳,以术后3个月气骨导差评价术后听力恢复情况:气骨差在15 dB以内22例;气骨差在20 dB以内2例;术后听力没有改变者8例;总有效率75%。结论:鼓室成型Ⅰ期听骨链重建可以使患者术后在获得干耳的同时有一好的听力。同时又有许多因素导致术后听力不提高。
OBJECTIVE: To investigate the postoperative hearing status and the causes of postoperative hearing loss in open tympanoplasty patients with stage I ossicular chain reconstruction. Methods: To summarize the hearing recovery of 32 cases undergoing tympanoplasty in our department from March 2005 to July 2007 with stage ossicular reconstruction. Results: The patients were followed up for 2 to 3 years. All patients were treated with dry ear. The postoperative 3-month follow-up evaluation of the airway deafness was used to evaluate the postoperative hearing recovery: 22 cases whose air-sac difference was less than 15 dB; 2 cases; no change in hearing after surgery in 8 cases; the total effective rate of 75%. Conclusions: Tympanoplasty stage I reconstruction of ossicular chain can make patients have good hearing after obtaining dry ears. At the same time there are many factors that lead to increased hearing after surgery.
