CT scans of 35 patients were obtained during rapid drip infusion of contrast material to determine the range of normal variation in the structures of the oropharynx and the floor of the mouth. Superficial structures such as the tonsillar pillars and lingual and faucial tonsils vary so much in appearance that they are not useful indicators in the detection of subtle lesions; in fact, they are potential sources of "pseudomasses." Asymmetric obliteration of the parapharyngeal space is useful for the detection of subtle lesions of the upper tonsillar fossae; however, confident diagnosis in regard to the lower oropharynx depends on visualization of a mass lesion or loss of the more constant planes in the floor of the mouth and the tongue base. CT findings added unique and valuable information in eight of 12 cases of carcinoma, confirmed the clinical impression of the extent of the lesion in four cases, and were potentially misleading in one case. CT is a valuable adjunct to the detection and staging of an oropharyngeal malignancy.
对35例患者在快速滴注造影剂期间进行CT扫描，以确定口咽和口底结构的正常变异范围。诸如扁桃体柱、舌扁桃体和咽扁桃体等浅表结构外观差异很大，在检测细微病变时并非有用的指标；事实上，它们是“假肿块”的潜在来源。咽旁间隙的不对称闭塞有助于检测扁桃体上隐窝的细微病变；然而，对于口咽下部的可靠诊断取决于是否能看到肿块病变或口底和舌根更恒定平面的消失。在12例癌病例中，CT检查结果在8例中提供了独特且有价值的信息，在4例中证实了病变范围的临床印象，在1例中可能产生误导。CT是检测口咽恶性肿瘤及其分期的有价值辅助手段。
