Abstract：
To report the case of the simultaneous treatment of otosclerosis and malleus fixation through an entirely endoscopic transcanal approach. A targeted transcanalar epitympanotomy with annular bony ridge conservation was planned preoperatively, with 3D CT localization of the fixed part of the malleus head. The upper part of the malleus head and the superior ossified ligament of the malleus were drilled. A 0.6 mm stapedotomy was performed and a piston inserted. The patient\'s recovery was uneventful, with closure of the air-bone gap on her postoperative audiogram, associated with an overclosure in 500Hz, 1kHz, 2 kHz and 4 kHz.

摘要：
报告通过完全内窥镜经管入路同时治疗耳硬化症和锤骨固定的病例。术前计划进行针对性的经颅鼓膜切开术，并保留环形骨脊，通过3DCT定位锤头的固定部分。锤骨头部的上部和锤骨的上骨化韧带被钻孔。进行0.6mm的钳制切开术并插入活塞。病人的康复顺利，她术后听力图上的气-骨间隙闭合，与500Hz的过度封闭相关，1kHz,2kHz和4kHz。喉镜,2023年。
