A review of 23 consecutive patients with tumors of the nasopharynx and maxillary sinus seen over a two-year period was carried out. The purpose was to assess the value of computerized tomography (CT) in the definition of tumor extension to contiguous structures and its effect on treatment selection and management.CT was found to be very useful in detailing bone and soft-tissue invasion. In 11 of 15 patients with nasopharyngeal cancer and in the eight patients with maxillary sinus tumors, the selection of treatment and the techniques of irradiation were influenced by the CT findings.There is a high degree of accuracy in the evaluation to the nasopharynx and maxillary sinus by CT. This improvement in pretreatment assessment of the tumors enables adequate treatment to be offered. Since most of the failures of treatment are a result of local recurrence, improvement in local control is likely to result in improved survival.
对在两年期间连续收治的23例鼻咽癌和上颌窦肿瘤患者进行了回顾性研究。目的是评估计算机断层扫描（CT）在确定肿瘤向相邻结构扩展方面的价值及其对治疗选择和管理的影响。发现CT在详细显示骨和软组织侵犯方面非常有用。在15例鼻咽癌患者中的11例以及8例上颌窦肿瘤患者中，治疗选择和放疗技术受到CT检查结果的影响。CT对鼻咽和上颌窦的评估具有高度准确性。肿瘤治疗前评估的这种改善使得能够提供充分的治疗。由于大多数治疗失败是局部复发的结果，改善局部控制可能会提高生存率。
