炭材料在听力重建术中的临床应用

目的：通过对应用了炭材料的听力重建手术68耳的分析,探讨炭质材料在听力重建手术中的相关问题。方法：慢性单纯性中耳炎2例,骨疡型中耳炎3例,胆脂瘤型中耳炎63例,均应用炭材料修复并行Ⅰ期听力重建手术。结果：术后患者随访时间1.5～9年,听力提高30dB以上者17耳,听力提高10～30dB者47耳,听力无提高者4耳（其中因术后感染致人工听骨经新鼓膜排出者2耳）。结论：炭质材料应用于耳科在彻底清除病变基础上可行Ⅰ期听力重建术,缩短了患者治疗时间,是一种具有推广价值的赝复材料。

Clinical application of carbon material in audile reconstruction

Objective Through 68 patients undergoing audile reconstruction with carbon material,to discuss the relative problems of carbon materials in the audile reconstruction.Method Two cases of chronic otitis media simplex,3 of otitis media caries,and 63 of otitis media cholesteatoma were all repaired with carbon materials and operated with stage I audile reconstruction.Results Postoperative follow-up lasted for 1.5~9 years,and audition increased more than 30dB in 17 patients,increased 10~30dB in 47,no increase in 4(including 2 cases of artificial auditory ossicles expelling through tympanum because of postoperative infection).Conclusion Carbon material can apply in stage I audile reconstruction on the basis of cleaning up focus in otology operation,and can shorten the therapy time.Carbon material is a good simulative material with popularized value.
