外耳道乳头状瘤是发生在外耳道皮肤的良性肿瘤。多发生于外耳道软骨部,我国南方地区多见。其治疗方法一般均手术摘除,但往往因不彻底而致复发,特别是位置较深和多发性者。多次复发有恶变可能,手术治疗会给患者带来一定痛苦,因故不能手术或惧怕手术者常因之延误病情。我们采用宁德地区二院顾态成介绍的用氟脲嘧啶注射治疗外耳道乳突状瘤的方法,从1983年起治疗50例 The external auditory canal papilloma is a benign tumor that occurs in the external auditory canal skin. Occurred in the external ear canal cartilage, more common in southern China. The treatment is generally surgical removal, but often due to incomplete recurrence, especially in the deeper and more frequently. Multiple recurrences may cause malignant transformation. Surgical treatment may cause some pain to the patient. For some reason, surgery or fear of surgery often causes delays in the patient’s condition. We used the method of injection of fluorouracil introduced by Gu Yuancheng of Ningde District to treat the external ear canal papilloma. 50 cases have been treated since 1983.
