Although cholesteatomas are more commonly found in the middle ear and the mastoid, the disease can occur in the external ear canal. All cases of ear canal cholesteatoma treated by the author were reviewed. There were nine ears in seven patients, who had an average age of 62 years. The lesions ranged in size from a few millimeters to extensive mastoid destruction. Smaller lesions can be managed by frequent cleaning as an office procedure. Larger lesions require surgery, either canaloplasty or mastoidectomy. The otolaryngologist should suspect this disease in the elderly. Microscopic examination of the ear with meticulous cleaning of all wax, especially in elderly patients, is most useful in detecting early disease. Frequent applications of mineral oil to the canal should be used in the management of the disease and to prevent recurrence.
虽然胆脂瘤更常见于中耳和乳突，但该病也可发生在外耳道。作者回顾了所有经其治疗的外耳道胆脂瘤病例。7名患者共9只耳朵，平均年龄62岁。病变大小从几毫米到广泛的乳突破坏不等。较小的病变可作为门诊手术通过频繁清理来处理。较大的病变需要手术，即外耳道成形术或乳突切除术。耳鼻喉科医生应怀疑老年患者患有此病。对耳朵进行显微镜检查并仔细清理所有耵聍，尤其是老年患者，这对早期疾病的检测最为有用。在疾病的治疗和预防复发方面，应经常向外耳道涂抹矿物油。
