Staging of malignant tumors of the nasal cavity and paranasal sinuses by computed tomography (CT) was studied in a total of 49 patients, 33 with squamous cell carcinoma and 16 with tumors of other histologic types. Involved sites by the tumor were studied, and clinical staging was made using CT findings alone according to AJC classification for maxillary sinus tumors. Surgical findings for comparison were available for most cases. Of 33 squamous cell carcinomas and of 16 tumors with other histologic types, the maxillary sinus was the site of origin in 29 and eight, respectively. Of these 37 maxillary sinus tumors, 11 were staged T3, 26, T4, and none was staged T1 or T2. None of these tumors were down staged, and one T3 was upstaged after surgical procedures, although all sinuses were not explored in some cases. Sinusitis due to obstruction was indistinguishable from the tumor without bone destruction. And the determination of the site of origin was difficult in some cases. Despite these, CT should be used for pretreatment evaluation of the tumors of these sites.
我们对49例鼻腔和鼻窦恶性肿瘤患者进行了计算机断层扫描（CT）分期研究，其中33例为鳞状细胞癌，16例为其他组织学类型的肿瘤。研究了肿瘤累及的部位，并根据美国癌症联合委员会（AJC）对上颌窦肿瘤的分类，仅使用CT检查结果进行临床分期。大多数病例都有可供比较的手术结果。在33例鳞状细胞癌和16例其他组织学类型的肿瘤中，上颌窦分别是29例和8例的原发部位。在这37例上颌窦肿瘤中，11例分期为T3，26例为T4，无T1或T2期。这些肿瘤均未降期，1例T3期肿瘤在手术后升期，不过在某些病例中并非对所有鼻窦都进行了探查。阻塞性鼻窦炎在无骨质破坏时与肿瘤难以区分。而且在某些病例中，确定原发部位也很困难。尽管如此，CT仍应用于这些部位肿瘤的治疗前评估。
