摘　　要：目的比较足板小孔开窗与镫骨全切除术治疗耳硬化症的疗效。方法回顾性分析1993年至2004年资料完整的部分耳硬化症病例63例(73耳),统计足板小孔开窗术27例(30耳)和镫骨全切除术36例(43耳)患者的术后听力和并发症等指标,比较两种术式的优劣。结果两组术后言语频率纯音平均听阈气骨导差缩小无明显差异,但在高频气骨导差改善及减少术后高频听力损失和眩晕方面,足板小孔开窗术明显优于镫骨全切除术,并有统计学意义。结论足板小孔开窗与镫骨全切除术在提高耳硬化症病人的听力方面均具有较好的疗效,而足板小孔开窗可更好地提高高频听力、减少术后并发症的发生。Objective To compare the effect of small fenestra stapedotomy and total stapedectomy in patients with otosclerosis. Methods Twenty-seven patients （30 ears） undergoing small fenestra stapedotomy and 36 patients （43 ears） receiving total stapcdectomy were compared for heating results and complication rates. Results No statistically significant differences were seen in postoperative speech pure tone average in closing air-bone gap between the two groups. The ears treated by small fenestra stapedotomy showed statistically better air-bone gap closure at high frequencies with lower rates of sensorineural hearing loss at high frequencies and milder dizziness. Conclusion In spite of the successful hearing outcomes in both groups, small fenestra stapedotomy can achieve better results at high frequencies and reduce the incidence of complications.
