收集并分析了疗前鼻咽癌伴颈淋巴结转移者 2 5 4例 ,探讨其咽旁间隙和 /或“茎内”受界与颈淋巴结的关系。结果　本组鼻咽癌单侧颈淋巴结转移率 78.35 % ,双侧者 2 1.6 5 %。“茎内”和咽旁间隙受累与颈淋巴结转移有关 ,但与其大小无关。鼻咽癌仅累及鼻咽一侧时 ,颈淋巴结转移与侵犯鼻咽部位多少无关 ;双侧“茎内”受界与同时伴单侧或双侧咽旁间隙受累 ,两者颈林巴结转移率无差别。鼻咽癌累及双侧“茎内”合并单侧咽旁间隙受累比合并双侧咽旁间隙受累 ,其单侧颈淋巴结转移率较高 ,双侧颈淋巴结转移率较低 ,而双侧“茎内”或咽旁间隙受累比单侧“茎内”或咽旁间隙受累 ,其双侧颈淋巴结转移则较高 Collected and analyzed 254 cases of nasopharyngeal carcinoma with cervical lymph node metastasis before treatment, to explore the parapharyngeal space and / or “stem” bound and cervical lymph node relationship. Results The nasopharyngeal carcinoma in this group had 78.35% unilateral neck lymph node metastasis and 2 1.6 5% bilateral. “Stem” and parapharyngeal space involvement is associated with cervical lymph node metastasis, but not with its size. Nasopharyngeal carcinoma involving only one side of the nasopharyngeal, cervical lymph node metastasis and the number of violations of the nasopharynx has nothing to do; both sides of the “stem” bound with simultaneous unilateral or bilateral parapharyngeal space involvement, both cervical junction metastasis rate No difference. Nasopharyngeal carcinoma involving both sides of the “stem” with unilateral parapharyngeal space involvement than the bilateral parapharyngeal space involvement, the unilateral neck lymph node metastasis rate was higher, lower cervical lymph node metastasis rate, and bilateral “stem Internal ”or parapharyngeal space involvement than unilateral“ stem ”or parapharyngeal space involvement, the bilateral cervical lymph node metastasis is higher
