Radiotherapy is an accepted part of the treatment of malignant tumours of the parotid gland. The use of radiotherapy in benign parotid tumours, where spillage of tumour cells has occurred at operation, is more controversial. Radiotherapy to the parotid bed is not without morbidity. Complications may arise as a result of radiation damage to neighbouring structures and there is also potential to induce malignant disease. A patient, whose postoperative radiotherapy following resection of a pleomorphic salivary gland adenoma was complicated by cerebral necrosis, is discussed. The literature pertaining to morbidity of radiotherapy for parotid tumours is reviewed.
放射治疗是腮腺恶性肿瘤治疗中被认可的一部分。对于良性腮腺肿瘤,在手术中发生肿瘤细胞溢出时使用放射治疗更具争议性。对腮腺床进行放射治疗并非没有并发症。并发症可能因对邻近结构的辐射损伤而产生,并且也有诱发恶性疾病的可能性。本文讨论了一名患者,其在切除多形性腺样囊性癌后进行术后放射治疗时出现了脑坏死并发症。同时对有关腮腺肿瘤放射治疗并发症的文献进行了综述。
