Tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .This paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.
Sixty referring patients to specialty and subspecialty clinics between the age 15 to 60 years-old were selected. All patients suffered from Chronic Otitis Media and they were categorized into two groups: a) those with wet ears and b) those with dry ears. Tympanoplasty surgery was performed through the use of embedding technique of temporalis fascia graft and in medial position (Medial Graft Technique). Finally, the data about the level of hearing improvement and the repair of tympanic membrane were analyzed.
Although there was hearing improvement in both groups - with wet or dry ear - no statistically significant difference was observed between two groups. Following the surgery, tympanic membrane in two patients with wet ear and one with dry ear was not repaired, however according to the statistical analysis this difference was not significant.
The results of this study showed that in contrast to the common perception that tympanoplasty results in the patients with wet ear is poorer than those with dry ear, there was little difference in the results of the operations performed on two groups.
鼓室成形术是鼓膜穿孔闭合的标准且成熟的手术方法。本文比较了鼓膜慢性穿孔患者在手术时有或无活动性引流的两组患者鼓室成形术在听力改善和移植物整合方面的结果。
选取60例年龄在15至60岁之间转诊至专科和亚专科诊所的患者。所有患者均患有慢性中耳炎，他们被分为两组：a）耳湿组和b）耳干组。鼓室成形术采用颞肌筋膜移植物嵌入技术并在内侧位置进行（内侧移植物技术）。最后，分析了听力改善水平和鼓膜修复的数据。
尽管耳湿组和耳干组患者术后听力均有改善，但两组之间未观察到统计学上的显著差异。术后，两名耳湿患者和一名耳干患者的鼓膜未修复，然而根据统计分析，这种差异并不显著。
本研究结果表明，与普遍认为的耳湿患者鼓室成形术效果比耳干患者差的观点相反，两组手术结果几乎没有差异。
