摘要
目的研究儿童外耳道胆脂瘤的临床特征。方法回顾性分析了2005年3月至2010年3月重庆医科大学附属儿童医院耳鼻咽喉科收治的32例(33耳)外耳道胆脂瘤患儿的临床资料,包括病因、相关症状、内镜及CT特征、治疗结果。结果患儿的平均年龄8.3岁(3～14岁),男26例,女6例。单耳发病31例,右耳多见,占21例。耳流脓和听力损害是最常见症状。伴耳道肉芽形成者22耳,骨质破坏仅5耳。8耳行单纯外耳道胆脂瘤清除术;22耳伴有外耳道肉芽者,行外耳道肉芽切除术及外耳道胆脂瘤清除术,3耳伴有外耳道狭窄行外耳道胆脂瘤清除术及外耳道成形术。经治疗后32例患儿随访2～7年无复发。结论儿童外耳道胆脂瘤报道率低,多为自发性,早期的诊断和治疗是关键。
Objective To investigate the characteristics of pediatric external auditory canal cholesteatoma（EACC）.MethodsChart review of thirty-two children with EACC between Mar.2005 and Mar.2012 was performed with subsequent analysis of etiologic factors,associated symptoms,otoscopic findings,imaging features,and treatment outcomes.Results The average age of patients was 8.3 years（range 3-14 years）.There were 26 boys and 6 girls.There was greater incidence of EACC on the right side（21 of 32 patients）.Otorrhea and hearing impairment were the most common presenting symptoms.There were 22 ears with external auditory canal granulation tissue and only 5 ears with bony erosion of the external ear canal on temporal bone CT.Eight ears underwent cholesteatoma removal.Twenty-two ears were treated with combined removing EACC and resection of granulation tissue.Three ears underwent canaloplasty of external auditory meatus.No recurrence was found during the follow-up period.Conclusion Pediatric EACC is underreported.Most of them were spontaneous.Early diagnosis and treatment is essential in the management of pediatric EACC.
