自体听骨与钛合金人工听骨在听骨链重建术中的疗效对比研究

Comparative study on the effects between self-incur and Titanium alloy artificial ossicle replacement pros-thesis in reconstruction of ossicular chain

目的通过自体听骨与钛合金人工听骨在听骨链重建术中疗效的对比观察,寻求农村基层医院听骨链重建术最佳材料。方法对31耳接受钛合金人工听骨植入进行陈旧性中耳炎听骨链重建的患者及35耳接受自体听骨植入进听骨链重建的患者,随访6个月~3年、资料完整的病例进行回顾性总结分析,进行疗效对比。计算语言频率(0.5、1及2 k HZ)平均听力,比较钛合金人工听骨及自体听骨植入的疗效。结果两组植入物间术后纯音测听语言频率,听力提高情况对比差异无统计学意义(P>0.05)。结论自体听骨是农村基层医院听骨链重建术中理想的材料。

Objective To observe the effect of self-in- cur and titanium prosthesis in reconstruction of ossicular Chain, to seek preferable materials for reconstruction of ossic- ular chain in the rural grass-roots hospital. Methods The efficacy of ossicular reconstruction with titanium prosthesis and self-incur were retrospectively summed up in 31 ears and 35 ears. All patients were followed up for 6 months to 3 years. All patients were examined by audiometric mea- surement （the average hearing threshold at 0.5, 1.0, 2.0 kHz） before and after reconstruction of ossicular chain. Results Hearing improvement of speech frequency of pure tone audiometry between two different groups was not statistically different （P〉0.05） . Conclusion Self-in- cur is the ideal material for reconstruction of ossicular chain in rural grass roots hospitals.
