To evaluate the therapeutic effect that the titanium partial ossicular reconstruction prosthesis and autologous ossicles have on hearing loss after reconstruction of a damaged ossicular chain.
Forty-two medical records of treatments carried out from 2013 to 2015 for ossicular chain damage with facial nerve paralysis due to temporal bone fractures were reviewed. The study assessed: causes of damage, pre-operative pure tone audiometry findings, types of intra-operative ossicular chain damage, intra-operative ossicular chain repair methods (titanium partial ossicular reconstruction prosthesis or autologous ossicles) and post-operative pure tone audiometry results.
The titanium partial ossicular reconstruction prosthesis was used in 26 cases; the average air-bone gap was 32.3 ± 5.3 dB pre-operatively and 12.8 ± 5.3 dB post-operatively. Autologous ossicles were used in 16 cases; the average air-bone gap was 33.4 ± 4.5 dB pre-operatively and 17.8 ± 7.8 dB post-operatively.
Ossicular chain reconstruction is an effective way of improving hearing in patients with ossicular chain damage. The results suggest that repair with either the titanium partial ossicular reconstruction prosthesis or autologous ossicles can improve hearing following ossicular chain injury with facial nerve paralysis caused by a temporal bone fracture.
评估钛质部分听骨链重建假体和自体听骨对受损听骨链重建后听力损失的治疗效果。
回顾了2013年至2015年因颞骨骨折导致听骨链损伤伴面神经麻痹而进行治疗的42份病历。该研究评估了：损伤原因、术前纯音听力测定结果、术中听骨链损伤类型、术中听骨链修复方法（钛质部分听骨链重建假体或自体听骨）以及术后纯音听力测定结果。
26例使用了钛质部分听骨链重建假体；术前平均气骨导间距为32.3±5.3dB，术后为12.8±5.3dB。16例使用了自体听骨；术前平均气骨导间距为33.4±4.5dB，术后为17.8±7.8dB。
听骨链重建是改善听骨链损伤患者听力的有效方法。结果表明，使用钛质部分听骨链重建假体或自体听骨进行修复均可改善因颞骨骨折导致的听骨链损伤伴面神经麻痹后的听力。
