To evaluate the efficacy and safety of a titanium total prosthesis (TORP) in ossicular chain reconstruction.
Retrospective analysis of 113 cases of total ossicular chain reconstruction performed by a single surgeon between 2006 and 2018. Follow-up lasted until January 2020. Participants were patients with chronic otitis media, cholesteatoma, or ossicular chain disruption.
Mean preoperative air-bone gap (± standard deviation) was 32.74 dB (± 11.62). Mean postoperative air-bone gap was 21.68 (± 11.29). Mean air-bone gap improvement was 11.06 dB (± 14.99) (p < 0.001). 57 cases had a post-operative air-bone gap smaller than or equal to 20 dB (50.44%). In four cases, prosthesis dislocation was observed (12.39%). Mean prosthesis length in this group was 5.29 mm (± 0.86) versus 4.36 mm (± 1.02) in cases without prosthesis dislocation (p = 0.002).
Total ossicular reconstruction using a titanium prosthesis yields favorable functional results, also during prolonged follow-up. Prosthesis length was significantly longer in cases with prosthesis dislocation.
评估钛质全听骨假体（TORP）在听骨链重建中的疗效和安全性。
回顾性分析了 2006 年至 2018 年间由一位外科医生进行的 113 例全听骨链重建病例。随访持续到 2020 年 1 月。参与者为患有慢性中耳炎、胆脂瘤或听骨链中断的患者。
平均术前气骨导差（±标准差）为 32.74dB（±11.62）。平均术后气骨导差为 21.68dB（±11.29）。平均气骨导差改善 11.06dB（±14.99）（p＜0.001）。57 例术后气骨导差小于或等于 20dB（50.44%）。4 例观察到假体脱位（12.39%）。在这组病例中，假体长度平均为 5.29mm（±0.86），而在无假体脱位的病例中平均为 4.36mm（±1.02）（p=0.002）。
使用钛质假体进行全听骨重建可获得良好的功能结果，且在长期随访中亦如此。在发生假体脱位的病例中，假体长度明显更长。
