To compare the surgical time, auditory outcomes and safety between microdrill and diode laser in endoscopic stapedotomy. The data of patients with otosclerosis who underwent endoscopic stapedotomy in Eye and ENT Hospital of Fudan University from January 2020 to December 2023 were retrospectively analyzed. The patients were divided into microdrill group and laser group according to treatment method. Surgical time, hearing level and complications were compared between the two groups. A total of 148 patients (41 males and 107 females) aged (42.8±7.7) years were included. There were 81 cases in the microdrill group and 67 cases in the laser group, respectively. No statistically significant differences in age, gender, duration of disease and surgical side were detected between the two groups (all >0.05). Preoperative air-bone gap (ABG) was (27.0±5.5) decibel hearing level (dB HL) in microdrill group and (25.0±5.1) dB HL in laser group, with no statistically significant difference (=0.191). Postoperative ABG was (14.0±2.6) dB HL and (12.1±2.7) dB HL in microdrill group and laser group, respectively, and there was no statistically significant difference between the two groups (=0.595). Compared with preoperative results, postoperative ABG decreased in both groups (both <0.05). Postoperative vertigo was observed in 7 patients (8.6%) in the microdrill group and 6 patients (9.0%) in the laser group, respectively (=0.947). The surgical time in microdrill group [(53.0±9.0) min] was shorter than that in laser drilling group [(59.3±12.8) min] (<0.001). Postoperative improvement in hearing level after microdrill is similar to diode laser, but microdrill has shorter surgical time.
比较微型钻头和二极管激光在内镜下镫骨手术中的手术时间、听觉效果及安全性。回顾性分析2020年1月至2023年12月在复旦大学附属眼耳鼻喉科医院接受内镜下镫骨手术的耳硬化症患者的数据。根据治疗方法将患者分为微型钻头组和激光组。比较两组的手术时间、听力水平及并发症。共纳入148例患者（男41例，女107例），年龄（42.8±7.7）岁。微型钻头组81例，激光组67例。两组在年龄、性别、病程及手术侧别方面差异均无统计学意义（均>0.05）。微型钻头组术前气骨导间距（ABG）为（27.0±5.5）分贝听力级（dB HL），激光组为（25.0±5.1）dB HL，差异无统计学意义（P = 0.191）。微型钻头组和激光组术后ABG分别为（14.0±2.6）dB HL和（12.1±2.7）dB HL，两组间差异无统计学意义（P = 0.595）。与术前结果相比，两组术后ABG均降低（均<0.05）。微型钻头组有7例患者（8.6%）出现术后眩晕，激光组有6例患者（9.0%）出现术后眩晕，差异无统计学意义（P = 0.947）。微型钻头组的手术时间[（53.0±9.0）分钟]短于激光钻孔组[（59.3±12.8）分钟]（P<0.001）。微型钻头术后听力水平的改善与二极管激光相似，但微型钻头的手术时间更短。
