摘要
目的通过自体听骨与人工听骨在听骨链重建术中远期疗效的对比观察,寻求听骨链重建术更好的材料。方法对接受人工听骨(PORP)植入进行陈旧性中耳炎听骨链重建的患者及接受自体听骨植入进听骨链重建的患者,随访半年以上、资料完整的病例进行回顾性总结,进行疗效对比分析。计算语言频率(分别为0.5、1、2 kHz)平均听力,比较PORP植入及自体听骨植入的疗效。结果两组植入物鼓膜修补术后纯音测听语言频率,听力提高情况间差异无统计学意义(P>0.05)。1个月复查所有患者均愈合良好,术后3个月至3年PORP植入组发现6例听骨脱出,自体听骨植入组未发现听骨吸收及排出现象,仅1例鼓膜再穿孔(胆脂瘤型中耳炎)。结论自体听骨是听骨链重建中理想的材料,优于PORP。
Objective To observe long-term effect of self-incus and partial ossicular replacement prosthesis（PORP） in reconstruction of ossicular chain,to seek preferable materials of reconstruction of ossicular chain.Methods The efficacy of ossicular reconstruction with PORP and self-incus were retrospectively summed up in 58 ears and 69 ears.All patients were followed up for six months to 3 years.All patients were examined by audiometric measurement（the average hearing threshold at 0.5,1.0,2.0 kHz） before and after reconstruction of ossicular chain.We also compared the influence of different inserts.Results Hearing improvement between two different inserts had no statistical difference（P〈0.05）.All patients healed well at one month.6 ears were discovered prolapsed auricular bone in PORP group at 3 month to 3 year,while no patients were discovered bone resorption or prolapse in self-incus group.Only 1 case of eardrum reperforation occurred in self-incus group（cholesteatoma tympanitis）.Conclusion Self-incus could be a useful and ideal materials in reconstruction of ossicular chain.with an advantage over PORP.
