【摘要】：目的:探讨耳屏软骨+颞肌筋膜在外耳道骨壁及皮肤缺损重建手术中的应用及治疗效果。方法:41例外耳道病变患者中,39例为外耳道胆脂瘤,2例为外耳道骨瘤。术中出现外耳道骨壁及皮肤缺损,乳突气房暴露,用耳屏软骨+颞肌筋膜对外耳道缺损骨壁及皮肤进行修复,并于术后3周、3个月、6个月和1年进行随访。结果:术后3周时,29例外耳道骨壁及皮肤缺损重建患者1期愈合,12例术区见肉芽生长,刮除肉芽,再次碘仿纱条填塞1周后,创面愈合;3个月时,所有患者外耳道术区上皮化,无外耳道狭窄发生;术后6个月、1年复查,外耳道形态正常,无外耳道骨壁塌陷及乳突气房暴露。结论:采用耳屏软骨+颞肌筋膜修复外耳道骨壁及皮肤缺损,取材方便,易于操作;修复的外耳道壁封闭了与外耳道相通的乳突气房;由于软骨的支撑,保持了外耳道的正常形态。
[Abstract]:Objective: to investigate the application and effect of temporalis fascia in reconstruction of bone wall and skin defect of external auditory canal. Methods 39 cases of cholesteatoma of external auditory canal and 2 cases of osteoma of external auditory canal were found in 41 cases. The defect of bone wall and skin of external auditory canal was found during the operation, and the papillary chamber was exposed. The bone wall and skin of external auditory canal defect were repaired with temporalis muscle fascia of auricular cartilage, and followed up at 3 weeks, 3 months, 6 months and 1 year after operation. Results: at 3 weeks after operation, 29 patients with reconstruction of bone wall and skin defect of external auditory canal showed granulation growth, granulation was scraped out, and the wound healed after filling with iodoform gauze for 1 week, and at 3 months, all patients had epithelization of external auditory canal. No stenosis of external auditory meatus occurred, 6 months and 1 year after operation, the shape of external auditory canal was normal, no bone wall collapse of external auditory meatus and exposure of mastoid chamber. Conclusion: the defect of bone wall and skin of external auditory canal is repaired by using the temporalis fascia of auricular cartilage, which is convenient and easy to operate. The repaired wall of external auditory canal has closed the mastoid air chamber which is connected with the external auditory canal, and because of the support of cartilage, Maintain the normal shape of the external auditory canal.
