摘　　要：在头颈部肿瘤中,放射性脑病一般发生于鼻咽癌放疗之后,而在外耳道和中耳癌放疗后发生的脑损伤并不常见。本文报告1例外耳道癌和1例中耳癌的患者术后放疗后发生了放射性脑病的病例,同时进行相关文献复习并讨论外耳道和中耳癌放疗后放射性脑病的发生机理、临床特征及治疗方法。虽然此病在外耳道癌和中耳癌中比较罕见,但在这类病人中还是应该提高警惕,注意其出现的可疑症状,尽早发现尽早处理。In treating head and neck tumors, radiation encephalopathy generally occurs following radiotherapy in pa- tients with nasopharyngeal carcinoma. It is not commonly seen in patients with external auditory meatus or middle ear carci- noma. This paper reports two cases of radiation encephalopathy after postoperative radiotherapy （1 for external auditory me- atus carcinoma and 1 for middle ear carcinoma）. Relevant literature is reviewed and pathogenesis, clinical manifestation and treatment of radiation encephalopathy following radiotherapy in relation to external auditory meatus and middle ear car- cinoma are discussed. Although radiation encephalopathy is rare in external auditory meatus or middle ear carcinoma, we must heighten our vigilance and pay attention to suspicious symptoms.
