摘要

過去四年來（民國六十二年十月至六十六年十月）有314例患者經門診檢查（296例）及放射線一般常規頭部攝影閱片（18例）時有疑似鼻咽瘤腫徵象，後經活體病理檢查證實為鼻咽癌之患者，在未經放射線治療前予以多向斷面攝影以硏究顱底骨受侵蝕的情形。經硏制分析結果發現在11-30歲患者39人中有29人顱底骨有被優蝕微象(79.6%)；31-50歲患者128人中79人之顫底骨被侵蝕(61.7%)；51歲以上患者147人中顱底骨受侵蝕者有84人(57.14%)。全部314人中顱底骨被侵蝕者有192人，其侵蝕率平均高達61.2%。如此高的顱底骨侵蝕率除姜，黃兩位醫師之統計較本文略低之外，在國外文戲上尚無類似之統計，僅提出以供醫界同仁之參考。

At the Department of Radiology of the Veterans General Hospital, 314 well documented cases of nasopharyngeal carcinoma with polytomographic examination have been seen between Oct. of 1973 to Oct. of 1977. There were 252 males and 62 females with the ratio of 4 to 1. The age distribution was from 14 to 76. The skull base was involved by the tumor in 192 of 314 patients (61.2%). In 18 of all these 314 patients (5.7%) the tumor was initially suspected by the presence of a soft tissue bulging mass over the posterior wall of the nasopharynx by the routine skull investigation.
It is concluded from this observation that regular skull study should be considered as the initial routine work up in patients with symptoms referring to the- ear, nose and throat in order to detect early carcinoma, especially in patient who was born in the area along the southeastern coast of China.
For assessment of tumor with bony invasion of the skull base, polytomographic evaluation is much superior than that of the regular skull films, and is the most clinic, 1 accurate method at the present time.
