First, to determine if prosthesis length plays a role in optimizing successful hearing outcomes in stapedotomy surgery; and second, to determine if patient factors such as height are correlated with prosthesis length.
Retrospective chart review.
Retrospective chart review of patients undergoing stapedotomy surgeries with adequate follow up. Length of prosthesis, pre-/postoperative audiograms, and follow-up data were obtained.
The primary group consisted of 227 cases. The prosthesis length ranged from 3.75 mm to 4.75 mm (median 4.25 mm). The greatest improvement in postoperative air-bone gap (ABG) occurred in the 4.25 mm group, and the least in the 3.75 mm group. Patient height showed a positive, although weak, correlation with prosthesis length. No findings reached statistical significance.
Accurate measurement of prosthesis length is important for successful postoperative hearing outcomes. There is a positive but not significant correlation between patient height and prosthesis length.
第一，确定人工镫骨长度在镫骨手术中优化听力成功结果方面是否起作用；第二，确定诸如身高之类的患者因素是否与人工镫骨长度相关。
回顾性病历审查。
对接受镫骨手术且有充分随访的患者进行回顾性病历审查。获取人工镫骨长度、术前/术后听力图以及随访数据。
主要组包括227例病例。人工镫骨长度范围为3.75毫米至4.75毫米（中位数为4.25毫米）。术后气骨导间距（ABG）改善最大的是4.25毫米组，最小的是3.75毫米组。患者身高与人工镫骨长度呈正相关，尽管较弱。没有结果达到统计学意义。
准确测量人工镫骨长度对术后听力成功结果很重要。患者身高与人工镫骨长度之间存在正相关但不显著。
