To review hearing results after implantation of a self-crimping stapes prosthesis.
Analysis of hearing results in patients implanted with a self-crimping stapes prosthesis at two academic hospitals from 2000 to 2004.
Seventy-nine ears were divided into short-term and intermediate follow-up groups. The mean postoperative air-bone gap (ABG), preoperative minus postoperative ABG, and preoperative minus postoperative bone conduction values were 5.7, 21.4, and 4.1 dB, respectively, for the short-term group, and 6.3, 22.3, and 4.7 dB, respectively, for the intermediate group. The ABG was <10 dB in 88 percent of the short-term group and in 79 percent of the intermediate group.
The self-crimping Nitinol stapes prosthesis provides excellent short-term and intermediate postoperative hearing results, and may overcome the limitations of stapes prostheses requiring manual crimping.
This paper provides evidence for the use of a self-crimping Nitinol stapes prosthesis, which may simplify hearing restoration surgery for stapes fixation.
回顾自卷曲镫骨假体植入后的听力结果。
对2000年至2004年在两家学术医院植入自卷曲镫骨假体的患者的听力结果进行分析。
79只耳朵被分为短期和中期随访组。短期组术后平均气骨导间距（ABG）、术前减去术后ABG以及术前减去术后骨导值分别为5.7 dB、21.4 dB和4.1 dB，中期组分别为6.3 dB、22.3 dB和4.7 dB。短期组88%以及中期组79%的患者ABG<10 dB。
自卷曲镍钛合金镫骨假体术后短期和中期听力结果良好，可能克服了需要手动卷曲的镫骨假体的局限性。
本文为使用自卷曲镍钛合金镫骨假体提供了证据，这可能简化镫骨固定的听力恢复手术。
