人工听骨在鼓室成形术中的应用

Effects of ossicular reconstruction with Partial ossicular replacement prostheses in tympanoplasty

目的探讨人工听骨在传导性耳聋患者鼓室成形手术中应用的效果。方法对传导性耳聋患者采用人工听骨赝复物（Partial ossicular replacement prostheses，PORP或Toutal ossicular replacement prostheses，TORP，美国美敦力公司）取代被破坏的和缺失的自体听小骨而将听骨链进行有效的链接。结果对施行该手术的患者进行随访6—47个月，鼓膜修补愈合良好，平均气导听阈降低27．8dB HL，术后听力提高有效率79．3％，没有患者发生排异反应和病变复发。结论应用人工听骨赝复物PORP或TORP对传导性耳聋患者重建听骨链行鼓室成形术是安全有效的。

Objective OEvaluate the effect of ossieular reconstruction with partial ossieular replacement prostheses （PORP） or toutal ossicular replacement prostheses （TORP） . Methods We effectively connected the ossicular chain used the PORP or TORP, replaced the destructive autologous ossicular. Results All the patients were followed-up for 6-47 months, the tympanic membrane got well, the averaged postoperative air conduction reduced 27.8 dB HL, the effectiveness was 79.3%. The recurrent and the reject reaction were zero. Conclusion It is considered that the PORP or TORP was a safety and useful material for ossieular reconstrction in the tympanoplasty.
