目的：探讨鼻咽癌原发灶部位、体征与鼻咽、颅底CT关系。材料与方法：分析1993年12月至1995年10月我院收治的110例鼻咽癌之临床表现及鼻咽、颅底CT扫描。结果：茎突内侧软组织受侵率为87．3％（96／110），颈淋巴结转移率为77．3％。原发灶位于侧壁单侧颈淋巴结转移为52．9％（18／34），双侧颈淋巴结转移为35．4％（12／34）；原发灶位于顶侧壁单侧颈淋巴结转移为48．4％（17／35），双侧颈淋巴结转移为40．0％（14／35）。鼻咽癌除了直接向各壁和周围邻近组织发展蔓延外，咽旁间隙受侵和颈淋巴结转移有直接关系。鼻咽癌原发灶部位与颈淋巴结转移亦有关。本组资料还说明茎突内侧软组织受侵的侧别对颈深上淋巴结转移和前后组颅神经损害有一定关系。
Objective: To investigate the relationship between the location and the sign of the primary tumor of nasopharyngeal carcinoma and the CT of the nasopharyngeal and skull base. Materials and Methods: The clinical manifestations of nasopharyngeal carcinoma and nasopharyngeal and skull base CT scans were analyzed in our hospital between December 1993 and October 1995. RESULTS: The invasion rate of the soft tissue inside the styloid process was 87.3% (96/110), and the cervical lymph node metastasis rate was 77.3%. The primary tumor located 52.9% (18/34) of unilateral cervical lymph node metastasis and 35.4% (12/34) of bilateral cervical lymph node metastases; the primary tumor was located in the unilateral cervical lymph node metastasis of the parietal side wall. It was 48.4% (17/35) and bilateral cervical lymph node metastasis was 40.0% (14/35). In addition to the direct propagation of nasopharyngeal carcinoma to each wall and surrounding tissue, there is a direct relationship between parapharyngeal space invasion and cervical lymph node metastasis. The primary tumor site of nasopharyngeal carcinoma is also related to cervical lymph node metastasis. This group of data also shows that the side of the styloid process soft tissue invasion of the upper cervical lymph node metastasis and cranial nerve injury before and after a certain relationship.
