OBJECTIVE
To assess the efficiency of ossiculoplasty procedures with the Kurz titanium ossicular prosthesis and evaluate prognostic factors for the functional results.
METHODS
Retrospective chart reviews were performed for ossiculoplasty involving Kurz titanium prostheses between 2006 and 2009 in the ENT Head and Neck Department of the hôpital Nord, Marseille, France.
RESULTS
The population studied was 70 patients, with 37 procedures using the partial (PORP) and 33 the total ossicular replacement prosthesis (TORP). Mean follow-up was 9 months. Pre- and postoperative audiological parameters on four frequency averages (0.5, 1, 2, and 3kHz) were compared according to AAO-HNS guidelines. A postoperative air-bone gap (ABG)≤20dB was obtained in 71.43% of the patients (86.49% for PORP, and 54.55% for TORP). The mean change in ABG was 12.45dB in cholesteatomatous otitis versus 13.41dB in non-cholesteatomatous otitis.
CONCLUSION
Increasing the length of the ossicular prosthesis, especially TORP, may improve postoperative functional results.
目的
评估 Kurz 钛质听骨假体在鼓室成形术中的应用效果，并评估功能结果的预测因素。
方法
对法国马赛 Nord 医院 ENT 头颈部科 2006 年至 2009 年间使用 Kurz 钛质假体进行的鼓室成形术进行回顾性病历分析。
结果
研究人群为 70 例患者，其中 37 例行部分（PORP）和 33 例行全听骨置换假体（TORP）。平均随访时间为 9 个月。根据 AAO-HNS 指南，比较了术前和术后四个频率平均值（0.5、1、2 和 3kHz）的听力学参数。71.43%的患者（PORP 为 86.49%，TORP 为 54.55%）术后气骨导差（ABG）≤20dB。胆脂瘤性中耳炎患者的 ABG 平均变化为 12.45dB，而非胆脂瘤性中耳炎患者的 ABG 平均变化为 13.41dB。
结论
增加听骨假体的长度，尤其是 TORP，可能会改善术后功能结果。
