头颈部晚期肿瘤伴有大于３ｃｍ直径或被膜破裂的颈淋巴结转移，其有效治疗通常包括原发肿瘤的广泛切除和根治性颈廓清，并随之行术后放疗。这些病人中有肿瘤侵及颈动脉者，颈廓清时应同时切除颈动脉；这就可能会由于脑缺血而导致严重的神经系统并发症。作者于１９７２～１９９? Advanced head and neck cancers with cervical lymph node metastases larger than 3 cm in diameter or with ruptured capsules usually require extensive resection of the primary tumor and radical neck dissection followed by postoperative radiotherapy. In these patients, tumors invade the carotid artery. When the neck is clear, the carotid artery should be resected at the same time; this may cause serious neurological complications due to cerebral ischemia. Authors from 1972 to 199?
