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 understand the curative effect of autologous otorhinal cartilage in tympanoplasty with severe retraction and retraction of tympanic membrane, or with severe melanosis in regenerating tympanic membrane. Methods Elective trabeculectomy was used in 11 patients with severe tympanic retraction and retraction of tympanic membrane, or in patients with severe edema of regenerative tympanic membrane. Five cases of simple eardrum repair were treated with tympanic membrane repair, 6 cases were treated with modified radical mastectomy and complete operation Retain the retracted tympanic membrane and place the tragus cartilage on its medial side. Results All the 11 cases survived. There were 5 cases with the frequency of tracheostomy ≤ 10 dB and 6 cases with the interval of tracheostomy ≤ 20 dB. Language frequency of air conduction increased by an average of 16.5 dB; this group did not find patients with hearing loss and tympanic membrane retraction. Conclusions The tympanoplasty of trabeculectomy with severe traumatic invagination and retraction of the tympanic membrane, or severe traumatic intima of the regenerative tympanic membrane can be easily performed with autologous trabeculectomy. Because of the complete retention of the invaginal tympanic membrane during operation, the supportive effect of tragus on the tympanic membrane , The surgical effect was significantly improved.
