摘要

结果:平均年龄28.5岁,年龄范围15 ~ 41岁,男女比例为1.3:1。所有患者均有间歇性耳漏和不同程度的听力损失。平均空气传导阈值术前为40.2 dB,术后为27.1 dB。术前气骨间隙26.9 dB,术后气骨间隙16.1 dB。术前组与术后组比较差异有统计学意义。空气传导阈值平均改善13.1 dB,气骨间隙平均改善10.8 dB。2 / 3(66%)患者空气传导阈值<15 db改善,17(34%)患者空气传导阈值≥15 db改善。本研究以术后听力在40db以内的患者比例为标准,46例(92%)患者达到该标准,40例(80%)患者术后AB间隙在20db以内。

Evaluation of hearing status after type I tympanoplasty
Results: The mean age was found 28.5 years with range from 15 to 41 years and male female ratio was 1.3:1. All patients had intermittent otorrhoea and varying degree of hearing loss. The mean air conduction threshold was 40.2 dB preoperatively and 27.1 dB post-operatively. Air-bone gap was found 26.9 dB in preoperative and 16.1 dB in post-operative group. The differences were statistically significant between preoperative and post-operative group. Thus mean improvement of air conduction threshold was 13.1 dB and air-bone gap was 10.8 dB. Two third (66.%) patients improved <15 db air conduction thresholds and 17(34%) improved ≥15 db air conduction thresholds. Using the proportion of patients with a postoperative hearing within 40 dB as the criterion, this study showed 46(92%) patients achieving this and 40(80%) patients achieving AB gap within 20 db postoperatively.
