摘　　要：目的:探讨先天性外耳道狭窄畸形合并外耳道胆脂瘤患者的临床特点和治疗经验。方法:回顾性分析2009年1月—2019年12月期间首都医科大学附属北京同仁医院耳鼻咽喉头颈外科收治的152例(153耳)先天性外耳道狭窄畸形合并外耳道胆脂瘤患者的临床资料,包括发病年龄、临床表现、体征、听力学、颞骨CT、手术方式等。根据术前影像学表现、术中所见和病理结果,152例患者均为先天性外耳道狭窄畸形合并外耳道胆脂瘤,在清理胆脂瘤的同时行外耳道成形和鼓室成形术。结果:所有患者术后随访2~2.5年,未见胆脂瘤复发,再造后的外耳道均宽敞。行听力重建的108耳,听力有明显改善,平均听阈下降20~35 dB。结论:外耳道口狭窄容易并发外耳道胆脂瘤,且外耳道胆脂瘤的发生与外耳道口直径直接相关,但发病早晚与外耳道口直径大小并无直接关系。伴耳廓畸形的严重先天性外耳道狭窄者,极易因耳后红肿破溃造成漏诊、误诊而延误治疗。对此类患者,要先处理胆脂瘤,再进行耳廓再造等整形相关手术。手术应避免耳后切口,为以后行耳廓再造手术创造条件。Objective:To investigate the clinical features,diagnosis,and treatment experience of congenital stenosis of an external auditory canal with external auditory canal cholesteatoma.Methods:The clinical data of 152 patients(153 ears)with congenital external auditory canal stenosis complicated with external auditory canal cholesteatoma treated in the Department of Otorhinolaryngology Head and Neck Surgery of Beijing Tongren Hospital affiliated to Capital Medical University from January 2009 to December 2019 were analyzed retrospectively,including the age of onset,clinical manifestations,signs,audiology,high-resolution computed tomography(HRCT)of the temporal bone,mode of operation and so on.According to the preoperative imaging findings,intraoperative findings,and pathological results,152 patients with congenital external auditory canal stenosis with external auditory canal cholesteatoma were treated with canaloplasty and tympanoplasty while clearing the cholesteatoma.Results:All patients were followed up for 2-2.5 years,there was no recurrence of cholesteatoma,and the reconstructed external auditory canal was spacious.The hearing levels of 108 ears who underwent hearing reconstruction were significantly improved,and the average hearing threshold was reduced by 20-35 dB.Conclusion:The stenosis of the external auditory meatus is easy to be complicated with cholesteatoma of the external auditory canal,and the occurrence of cholesteatoma of the external auditory canal is directly related to the diameter of the external auditory canal meatus.But the time of occurrence of the cholesteatoma is not directly related to the diameter of the external auditory canal.Severe congenital stenosis of the external auditory canal with auricle deformity is easy to be missed and misdiagnosed due to retroauricular redness,swelling,and ulceration.For this kind of patient,cholesteatoma should be treated first,and then plastic surgery such as auricle reconstruction should be performed.Retroauricular incisions should be avoided to create condi
