Postinflammatory atresia of the external meatus following recurrent external otitis or chronic otitis media has been treated in twenty-two ears with endaural excision of the fibrous tissue and coverage of the denuded drum and bone of the medial part of the external ear canal with a split-skin transplant. Primary and late results are presented. During the first six months postoperatively, the patients developed recurrent atresia. At follow-up, with a median observation time of five years, no further progression of atresia had occurred. Hearing improvement has been considerable after removal of the atresia, and in many ears the air-bone gap was closed, so the patient also benefited from the operation in the long run.
复发性外耳炎或慢性中耳炎后外耳道的炎性闭锁已在22只耳朵中通过耳内切除纤维组织并用中厚皮片移植覆盖外耳道内侧裸露的鼓膜和骨质进行治疗。呈现了初期和后期结果。术后前六个月,患者出现复发性闭锁。随访时,中位观察时间为五年,闭锁未进一步进展。去除闭锁后听力有显著改善,许多耳朵的气骨导差缩小,因此从长远来看患者也从手术中获益。
