摘　　要：目的比较半导体激光和机械足板小孔开窗术治疗耳硬化症的疗效。方法回顾分析了1998年至2007年资料完整的部分耳硬化症病例45例(50耳),对半导体激光足板开窗术26例(29耳)和机械足板小孔开窗术19例(21耳)患者的术后听力指标及并发症进行了统计分析。结果两组术后言语频率及高频纯音平均听阈气骨导差缩小无明显差异,但半导体激光组言语频率的术前气骨导差与术后气骨导差的差值明显大于机械造孔组,并有统计学意义。术后眩晕的发生机械造孔组高于半导体激光组。结论半导体激光组和机械造孔组在改善耳硬化症病人的听力方面均有较好的疗效,而半导体激光组能够更为明显的改善患者的听力,减少术后眩晕的发生。Objective To compare the effects of small fenestra stapedotomy with semiconductor diode laser and microdrill in patients with otosclerosis. Methods Twenty-six patients （29 ears） undergoing stapedotomy with semiconductor diode laser and 19 patients （21 ears） with microdrill were compared for the hearing results and complication rates. Results No statistically significant differences were found in postoperative speech frequency and high frequency pure tone average in closing the air-bone gap between the two groups. The ears treated by stapedotomy with semiconductor diode laser showed significantly better preoperative minus the postoperative air-bone gap and milder dizziness. Conclusion In spite of the good hearing outcomes in both groups, small fenestra stapedotomy with semiconductor diodelaser can achieve better results and reduce the incidence of complications.
