摘要目的 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27.8 dB 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.

abstractsObjective OEvaluate the effect of ossicular reconstruction with partial ossicular 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 ossicular reconstrction in the tympanoplasty.
