耳甲腔软骨-软骨膜复合物在上鼓室外侧壁重建加鼓膜成形术中的应用

Application of cartilage-perichondrium complexs of cavity of auricular concha in the reconstructions in atticus lateral wall and tympanoplasty

目的探讨耳甲腔软骨-软骨膜复合物的制作及其应用在上鼓室外侧壁重建加鼓室成形术的疗效。方法10耳局限上鼓室胆脂瘤，10耳慢性中耳炎，7耳鼓室硬化，5耳粘连性中耳炎，开放上鼓室清除病变后应用耳甲腔软骨-软骨膜复合物重建上鼓室外侧壁加鼓室成形术。结果32耳手术修复均一期愈合。术后随访0．3—3年，1耳胆脂瘤术后再穿孔。术前、术后3月骨气导间距分别为36dBHL和13．5dBHL，术后较术前平均缩小22．5dBHL。结论耳甲腔软骨-软骨膜复合物是上鼓室外侧壁重建、鼓室成形的理想材料，值得应用。

objective To investigate the making methods of cartilage-perichondrium complexs of cavity of auricular concha and the effect in reconstruction of atticus lateral wall and tympanoplasty. Method Among 10 ears of limited attic cholesteatoma, 10 ears of chronic otitis media, 7 ears of tympanosclerosis, 5 ears adhesive otitis media, chiseling attic , removing lesions and applying cartilage-perichondrium complexs of cavity of auricular concha to reconstruct atticus lateral wall and tympanoplasty. Results 32 ears achieved primary healing. Follow-up 0.3-3 years, 1 ears of chotesteatoma reperforated after operation. The hearing threshold of average pure-tone in air-bone gap reduced 22.5 dBHL. （Preoperation in 36 dBHL, Postoperation in 13.5 dBHL）.Conclusions Cartilage-perichondrium complex of cavity of auricular concha is ideal material in the construction of atticus lateral wall and tympanoplasty , and is worth to be applied.
