Objective:To investigate the clinical value of tympanic membrane repairment with modified ear canal flap under endoscope. Methods:A retrospective analysis was conducted on the clinical data of 62 patients who underwent simple tympanic membrane perforation repair surgery in our hospital from August 2019 to January 2023. All patients were divided into two groups: 37 cases in the otoscopy group and 25 cases in the microscope group. The surgical duration, postoperative pain response, and postoperative tympanic membrane healing and hearing recovery were compared between the two groups. Results:Compared with the microscope group, the total surgical duration of the otoscopy group was significantly shortened[（70.4±13.2） min vs. （102.8±17.5） min, P<0.001], and there was a statistically significant difference in postoperative VAS pain score[（3.1±1.2） vs. （6.5±1.4）, P<0.001]. The two groups achieved tympanic membrane healing and no infection occurred after operation. There was no significant difference in postoperative hearing recovery between the two groups（P>0.05）. Conclusion:Modified tympanic membrane repairment through otoscope can greatly shorten the operation time and reduce the hospitalization cost, which is more suitable for the application of primary hospitals.
目的：探讨耳内镜下改良外耳道皮瓣夹层法鼓膜修补术的临床应用价值。 方法：回顾性分析于2019年8月-2023年1月在首都医科大学附属北京安贞医院收治入院进行单纯鼓膜穿孔修补术的62例患者的临床资料，并将所有患者分为2组，耳内镜组37例，显微镜组25例，比较2组手术时长、术后疼痛反应，观察术后鼓膜愈合和听力恢复情况。 结果：耳内镜组与显微镜组比较，手术全时程显著缩短[（70.4±13.2） min vs.（102.8±17.5） min，P<0.001]，术后VAS疼痛评分差异有统计学意义[（3.1±1.2） vs.（6.5±1.4），P<0.001]。2组术后3个月平均气导阈值均较术前提高，差异无统计学意义（P>0.05）。耳内镜组术后1个月鼓膜愈合率为100%，显微镜组为92%；3个月2组均完全愈合。 结论：与显微镜下鼓膜修补术相比，耳内镜下经外耳道改良皮瓣夹层法鼓膜修补术可缩短手术时间、减轻术后疼痛，且2组间听力恢复情况和鼓膜愈合率无差异，更适合基层医疗单位开展应用。.
