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。
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 trapanoplasty 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 irmer-invaginated and thinnerturned. Because the inner-invaginated TM are perfectly reserved and propped up by tragal cartilage autografts, the therapeutic efficacy is obviously elevated.
