To compare endoscope-assisted microdrill stapedotomy with the conventional technique.
A retrospective comparative study of 37 otosclerosis stapes fixation surgeries performed with the conventional technique or the endoscope-assisted microdrill stapedotomy were evaluated. Audiometric data and intraoperative and postoperative complications were recorded.
The mean operating time was 128 min in the endoscopic group and 132 min in the conventional group, (p = 0.72). Residual air-bone gaps of ≤10 decibels were obtained in 83.3% and 47.4% of the patients in the endoscopic group and the conventional group, respectively, (p = 0.04). No footplate fractures and incidences of postoperative vertigo and chorda tympani nerve injuries were found in the endoscopic group. Postoperative vertigo was found in 31.6% of the conventional group, and 26.3% of the patients in the conventional group had undergone an endaural surgical approach owing to inadequate exposure under the microscope.
An endoscope-assisted microdrill stapedotomy was associated with significantly better hearing results, a lower postoperative vertigo rate, and fewer footplate fractures and chorda tympani nerve injuries than the conventional technique.
比较内镜辅助微钻镫骨切除术与传统技术。
对37例采用传统技术或内镜辅助微钻镫骨切除术进行的耳硬化镫骨固定手术进行回顾性比较研究。记录听力数据以及术中及术后并发症。
内镜组平均手术时间为128分钟，传统组为132分钟，（p = 0.72）。内镜组和传统组分别有83.3%和47.4%的患者获得了≤10分贝的残余气骨间隙，（p = 0.04）。内镜组未发现镫骨底板骨折以及术后眩晕和鼓索神经损伤的情况。传统组有31.6%的患者出现术后眩晕，并且由于显微镜下暴露不足，传统组有26.3%的患者采用了耳内手术入路。
与传统技术相比，内镜辅助微钻镫骨切除术的听力结果明显更好，术后眩晕率更低，镫骨底板骨折和鼓索神经损伤更少。
