【摘要】 目的了解自体耳屏软骨在鼓膜严重内陷回缩、或再生鼓膜严重菲薄内陷患者鼓室成形术中的疗效。方法将自体耳屏软骨用于11例鼓膜严重内陷回缩、或再生鼓膜严重菲薄内陷的患者,修补鼓膜,其中5例单纯行鼓膜修补,6例同期行乳突改良根治,术中完整保留内陷的鼓膜,将耳屏软骨置于其内侧。结果11例移植物均成活,术后语言频率气骨导间距≤10 dB 5例;气骨导间距≤20 dB 6例。语言频率气导平均提高16.5 dB;本组患者均未发现听力回降及鼓膜回缩。结论对鼓膜严重内陷回缩、或再生鼓膜严重菲薄内陷患者利用自体耳屏软骨行鼓室成形术,移植物易成活,因术中完整保留内陷鼓膜,利用耳屏软骨对鼓膜的支撑作用,手术疗效明显提高。更多还原

【Abstract】 Objective To investigate the therapeutic efficacy of tympanoplasty with tragal cartilage autografts in patients whose tympanic membranes(TM) are seriously inner-invaginated and retracted,or regenerated TM are seriously inner-invaginated and thinner-turned.Methods 11 patients received tympanoplasty with tragal cartilage autografts,5 of them received single reconstruction of TM and 6 of them also received modified radical mastoidectomy.During the operations,inner-invaginated TM was completely reserved and tragal cartilages were put in the inner side of TM.Results TM inner-invaginations were all successfully treated.Audiometric data were presented as a 3-frequency(500,1000,and 2000Hz) purtone average air-bone gap.After the operations,an air-bone gap of less than or equal to 10 dB was achieved in 5 patients,and less than or equal to 20 dB in 6 patients.Hearing was elevated 16.5 dB on average.Conclusion Tympanoplasty with tragal cartilage autografts has a good result in patients whose TM are seriously inner-invaginated and retracted,or regenerated TM are seriously inner-invaginated and thinner-turned.Because the inner-invaginated TM are perfectly reserved and propped up by tragal cartilage autografts,the therapeutic efficacy is obviously elevated.更多还原
