耳硬化症和鼓室硬化症的镫骨切除术

Stapedectomy in the patients with tympanosclerosis and otosclerosis

目的评估耳硬化症和鼓室硬化症镫骨切除术的效果。方法对10耳鼓室硬化症和75耳耳硬化症行镫骨切除术患者,其手术前后气骨导差,SRT,手术后气导听力增进进行了评估。结果行镫骨切除术的耳硬化症患者,气骨导差减至0～20dB范围的有效率达91%,气导听力增进22.6±5.4dB。行镫骨切除术的鼓室硬化症患者,气骨导差减至0～20dB范围的有效率达90%,气导听力增进28.4±4.6dB。结论镫骨切除术对耳硬化症和镫骨性鼓室硬化症均有良好疗效。

PURPOSE To evaluate the results of stapedectomy in patients with otoscle-rosis and tympanosclerosis.METHODS A retrospective review of 85 patients who underwent stapedectomies was conducted. In these patients, 10 ears had tympanosclerosis and 75 ears had otosclerosis,We evaluated the preoperative and postoperative air-bone gaps, SRT, and the preoperative and postoperative air conduction hearing improvement.RESULTS The patients with oto- sclerosis who underwent stapedectomies achieved the efficiency of 91% in the reduction of air-bone gap of 0-20 dB range with an air conduction hearing improvement of 22.6±5.4 dB. The patients with tympanosclerosis who underwent stapedectomies achieved the efficiency of 90% in the reduction of air-bone gap of 0 -20 dB range, with an air conduction hearing improvement of 28.4 ±4.6 dB.CONCLUSIONS Stapedectomies for otosclerosis and tympanosclerosis may obtain good results.
