Abstract

OBJECTIVE

Retrospectively analyzed the influences of preoperative acoustic immittance pressure balance tests and intraoperative wet ear findings in myringoplasty surgery results.

METHODS

One hundred and twenty-one chronic suppurative otitis media patients underwent myringoplasty surgeries were included and divided into functional group and non-functional group according to preoperative acoustic immittance pressure balance tests. Meanwhile, cases were divided into dry ear group and wet ear group according to intraoperative findings. Postoperative hearing improvement and perforation rate were compared between the two groups.

RESULTS

Functional group had 72 cases, including 58 dry ears and 14 wet ears. Non-functional group had 46 cases, including 19 dry ears and 27 wet ears. Postoperative hearing improvement rate in functional group was 85.5% (59/69), and 72.1% (31/43) in non-functional group (χ(2) = 2.230, P = 0.093). Perforation rate in functional group was 16.7% (12/72), significant higher when compared with 2.2% (1/46) in non-functional group (χ(2) = 4.626, P = 0.015). Postoperative hearing improvement rate in dry ear group was 85.3% (64/75), and 71.8% (28/39) in wet ear group (χ(2) = 2.213, P = 0.085) . Perforation rate in dry ear group was 12.8% (10/78), and 7.0% (3/43) in wet ear group (χ(2) = 0.472, P = 0.377).

CONCLUSIONS

Non-functional result of preoperative acoustic immittance pressure balance test had significant relationship with the intraoperative wet ear findings. It may result in lower postoperative hearing level, and lower perforation rate. Large sample studies should be carried out in future.

摘要

目的

回顾性分析术前声导抗压力平衡试验及术中中耳积液情况对鼓膜成形术手术效果的影响。

方法

纳入121例行鼓膜成形术的慢性化脓性中耳炎患者，根据术前声导抗压力平衡试验分为功能组和非功能组。同时，根据术中情况分为干耳组和中耳积液组。比较两组术后听力改善情况及穿孔率。

结果

功能组72例，其中干耳58例，中耳积液14例。非功能组46例，其中干耳19例，中耳积液27例。功能组术后听力改善率为85.5%（59/69），非功能组为72.1%（31/43）（χ² = 2.230，P = 0.093）。功能组穿孔率为16.7%（12/72），显著高于非功能组的2.2%（1/46）（χ² = 4.626，P = 0.015）。干耳组术后听力改善率为85.3%（64/75），中耳积液组为71.8%（28/39）（χ² = 2.213，P = 0.085）。干耳组穿孔率为12.8%（10/78），中耳积液组为7.0%（3/43）（χ² = 0.472，P = 0.377）。
