Objective

Compare outcomes between a microscopic and endoscopic technique for anterior tympanic membrane (TM) perforation.

Methods

Results of microscopic overlay (MT) and endoscopic tympanoplasty (ET) for management of anterior TM perforations from a single surgeon.

Results

There were 28 patients in the MT group and 35 in the ET group. The mean age was 7.1 years and 10.9 years (p < 0.001) MT and ET groups respectively. There was no statistical differences in perforation location (p = 0.1), etiology (p = 0.52) or size (p = 0.1) between both groups. Mean operating time was 119.0 min and 131.0 min in the MT and ET groups respectively (p = 0.23). Follow up was 30.9 months and 9.0 months (p = 0.001) MT and ET respectively. The perforation was successfully closed in 29 patients at 6 weeks in the ET (82.9%) and 25 in the MT (89.3%), p = 0.47. Adjusting for age revealed no significant difference between groups. Long term follow up, resulted in 10 failures (28.6%) and 7 patients (25.0%) in the ET and MT groups respectively, p = 0.75. Adjusting for the follow-up period or age, there was no significant difference between groups. The change in ABG and PTA measures were not statistically different between groups.

Conclusions

An anteriorly based ET is a novel technique for management of anterior TM perforations. Results from this pilot study indicate that this ET approach may be an appropriate alternative to MT for difficult to repair anterior perforations. A longer follow-up will be necessary to determine its role in these perforations.

比较两种不同的修复小儿前鼓膜穿孔技术

客观的

比较前鼓膜 (TM) 穿孔的显微和内窥镜技术之间的结果。

方法

单个外科医生对前 TM 穿孔进行显微覆盖 (MT) 和内窥镜鼓室成形术 (ET) 的结果。

结果

MT组28例，ET组35例。MT 和 ET 组的平均年龄分别为 7.1 岁和 10.9 岁 (p < 0.001)。两组在穿孔位置 (p = 0.1)、病因 (p = 0.52) 或大小 (p = 0.1) 方面没有统计学差异。MT 和 ET 组的平均手术时间分别为 119.0 分钟和 131.0 分钟（p = 0.23）。MT 和 ET 的随访时间分别为 30.9 个月和 9.0 个月（p = 0.001）。在 ET 中 29 名患者 (82.9%) 和 MT 中 25 名患者 (89.3%) 在 6 周时成功闭合穿孔，p = 0.47。年龄调整显示组间无显着差异。长期随访，ET 和 MT 组分别导致 10 例失败 (28.6%) 和 7 例患者 (25.0%)，p = 0.75。调整随访期或年龄，组间没有显着差异。ABG 和 PTA 测量值的变化在组间没有统计学差异。
