目的 :探讨 期整复术治疗先天性外耳、中耳畸形和外耳道闭锁并存的患者的疗效。方法 :耳廓成形术 :取自体肋软骨作支架 ,患耳颞部超薄皮瓣及皮下组织瓣包裹软骨支架形成再造耳廓。鼓室成形术 :根据鼓室畸形情况作 型或大鼓室 型成形术 ;外耳道再造 :用全厚皮片移植。结果 :术后随访 4～ 6年 ,全部病例外耳道宽畅 ,成形鼓膜完整。语言频率听阈降低均达到应用水平 ;再造耳 11耳成活 ,8耳外形满意。结论 : 期整复术是治疗外耳、中耳畸形和外耳道闭锁并存的有效方法。

Objective:To investigate the application of one stage otoptasty for congenital atresia of the external acoustic canal and malformations of the middle ear and the auricle. Method:patients with the ear malformations were given surgical reconstruction of one stage otoplasty. The auricle was reconstructed with the rib which was encapsuled with the superthin temporal flap. According to the malformations of the middle ear in patients, I style tympanoplasty and Ⅲ style tympanoplasty were carried out respectively. All patients were performed myringoplasty with temporal fascia and reconstructed the external acoustic canal with full thickness skin grafting. Result:A long term follow up (4～6 years)demonstrated that 11 ears were survival of which 8 ears figuration were ideal. The hearing improvement was observed in all patients.Conclusion:one stage otoplasty is effective for treatment of the congenital malformations of the external and middle ear.
