To analyse patients with cholesteatoma undergoing canal wall down mastoidectomy together with ossicular reconstruction with a titanium prosthesis, in order to identify factors associated with hearing outcomes.
Retrospective review of 97 cases undergoing single-stage surgical management.
All patients underwent canal wall down mastoidectomy. Kurz titanium ossicular prostheses were used for ossicular chain reconstruction. Pre-operative and post-operative air conduction and bone conduction hearing thresholds were obtained at 500, 1000, 2000 and 3000 Hz.
The mean pure tone average improved from 46.02 ± 14.54 dB pre-operatively to 29.32 ± 14.64 dB post-operatively, for both total and partial ossicular replacement prosthesis groups combined. The mean air-bone gap improved from 30.38 ± 11.12 dB pre-operatively to 15.62 ± 9.65 dB post-operatively, for both groups combined.
Reconstruction with a titanium prosthesis offers good functional results when performed during canal wall down surgery for advanced cholesteatoma, as a single-stage procedure.
分析接受开放式乳突根治术并使用钛质假体进行听骨链重建的胆脂瘤患者，以确定与听力结果相关的因素。
对97例行单阶段手术治疗的病例进行回顾性分析。
所有患者均接受开放式乳突根治术。使用Kurz钛质听骨假体进行听骨链重建。于术前及术后分别测量500、1000、2000和3000Hz频率下的气导和骨导听力阈值。
对于全听骨置换假体组和部分听骨置换假体组，平均纯音平均值从术前的46.02±14.54dB改善至术后的29.32±14.64dB。两组的平均气骨导间距从术前的30.38±11.12dB改善至术后的15.62±9.65dB。
在开放式手术治疗晚期胆脂瘤时，使用钛质假体进行单阶段听骨链重建可取得良好的功能效果。
