摘要
目的 :为使乳突根治术后耳向外耳道开放的乳突腔重新中耳化和一期行听力重建。方法 :用同种异体肋软骨为外耳道后壁重建材料、乳突充填材料、听骨链重建材料 ,对 71例乳突根治术后耳 (流脓 53耳 ,干耳 18耳 )作了中耳重建术。结果 :71耳术后经 6个月～ 5年随访 ,6 6耳重建中耳腔接近正常生理结构 ,听力提高 15dB以上或达应用水平 55耳 ,占 77 5% (55/71) ;听力提高未达 15dB11耳 ,占 15 5% (11/71) ;因不同原因失败 5耳占 7 0 % (5/71)。结论 :用同种异体肋软骨行乳突根治术后的中耳重建术 ,是解决乳突腔重新中耳化 ,听力重建 ,防止术腔感染的较理想术式。
Objective:To reconstruct middle ear structure for open mastoid antrum with external auditory canal after radical mastoidectomy in one-stage.Methods:71 ears of post-mastoidectomy (discharging 53 ears and dried up 18 ears)were undergone with reconstruction of middle ear.The posterior wall of external auditory canal,mastoid cavity and chain of ossicles were reconstructed by homologous costal cartilage.Results:66 ears of 71 cases are near normal structure followed up 6 months to 5 years after operations.The result showed hearing over 15dB are 55 ears(77 5%)and under 15dB are 11 cases(15 5%).Five cases(7 0%)were failed.Conclusion:Reconstruction of middle ear with homologous costal cartilage is a ideal surgery to reconstruct hearing structure and avoid infection of middle cavity after radical mastoidectomy.
