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 stapedectomy were compared for hearing 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.
目的
比较小开窗镫骨手术与全镫骨切除术治疗耳硬化症患者的效果。
方法
比较接受小开窗镫骨手术的27例患者（30耳）和接受全镫骨切除术的36例患者（43耳）的听力结果和并发症发生率。
结果
两组术后言语纯音平均气骨导差缩小值无统计学显著差异。小开窗镫骨手术治疗的耳在高频气骨导差闭合方面统计学上表现更好，高频感音神经性听力损失发生率更低，头晕症状更轻。
结论
尽管两组听力结果均成功，但小开窗镫骨手术在高频方面能取得更好效果，并降低并发症发生率。
