摘要
目的 :探讨用耳屏软骨 -软骨膜复合体行听力重建术的疗效。方法 :用自体耳屏软骨 -软骨膜复合体重建鼓膜和听骨链 ,并根据听骨链是否完整而采取了不同的术式。结果 :4 8耳手术穿孔均一期愈合。术后随访 18个月~ 5年半 ,未见再穿孔。术前、术后骨、气导间距分别为 2 2 .1d BHL和 6 .8d BHL ,术后较术前平均缩小 15 .3d BHL。结论 :耳屏软骨 -软骨膜复合体是修复鼓膜大穿孔的理想材料 ,并能起到槌骨和 /或砧骨的作用。
Objective: To investigate the effect of the application of tragus cartilage perichondrium composite in tympanoplasty.Methods:The tympanic membrane perforation and ossicular chains reconstruction by surgery of tympanoplasty using the tragus cartilage\|perichondrium composite autograft in 48 patients with otitis media(48 ears,27 males and 21 females,ranging in age from 10 to 59 years old) were completed from 1996 to 2000.Results:The tympanic perforation closure was achieved in all 48 patients undergoing cartilage\|perichondrium composite reconstruction.No recurrent perforation was found during the follow\|up period of 1 5~5 5 year.The hearing threshold of average pure\|tone in air\|bone gap (ABG) reduced 15 3dBHL(preoperation in 22 1dBHL,postoperation in 6 8dBHL respectively).The graft of cartilage\|perichondrium offered an excellent postoperative hearing results.Conclusion:The tragus cartilage\|perichondrium composite is an ideal material for repairing large tympanic membrane perforation.
