OBJECTIVE
To determine the efficacy of reversal steps stapedotomy in the treatment of otosclerosis.
METHOD
From January 2006 to December 2009, a total of 70 patients (81 ears) with otosclerosis who underwent stapedotomy were retrospectively evaluated. Among these 81 ears, 41 ears underwent classical stapedotomy and 40 ears underwent reversal steps stapedotomy. We compared the postoperative results of pure tone tes , the intraoperative complications of stapes and incus and the incidence rate of postoperative vertigo after surgery between the two groups.
RESULT
The rate of postoperative air bone gap < or = 20 dB was 70.7% in the classical stapedotomy group and was 80.0% in reversal steps stapedotomy group. There were no significant differences between the two groups (P =0.181). The reversal steps stapedotomy group seem to had less complications of stapes and incus. The incidence rate of postoperative vertigo in reversal steps stapedotomy group significantly lower than in classical stapedotomy group (P = 0.037).
CONCLUSION
Reversal steps stapedotomy can effectively improve the hearing of patients with otosclerosis and can reduce the complications of stapedotomy.
目的
确定镫骨切除术的反转步骤在耳硬化症治疗中的疗效。
方法
回顾性评估2006年1月至2009年12月期间共70例（81耳）接受镫骨切除术的耳硬化症患者。在这81耳中，41耳接受了经典镫骨切除术，40耳接受了镫骨切除术的反转步骤。我们比较了两组术后纯音测试结果、镫骨和砧骨的术中并发症以及术后眩晕的发生率。
结果
经典镫骨切除术组术后气骨导间距≤20dB的比例为70.7%，镫骨切除术反转步骤组为80.0%。两组之间无显著差异（P = 0.181）。镫骨切除术反转步骤组的镫骨和砧骨并发症似乎较少。镫骨切除术反转步骤组术后眩晕的发生率显著低于经典镫骨切除术组（P = 0.037）。
结论
镫骨切除术的反转步骤可有效改善耳硬化症患者的听力，并可减少镫骨切除术的并发症。
