目的：目的：探讨CT在上颌牙龈癌和硬腭癌诊断中的价值。方法：回顾性分析27例上颌牙龈癌和硬腭癌患者的CT表现，并与手术和病理结果进行比较，评价CT对上颌牙龈癌和硬腭癌的敏感性、特异性和准确性。89%的患者通过CT发现了原发肿瘤。CT所确定的骨破坏程度与手术或组织病理学检查所证实的骨破坏程度相关。CT诊断颊粘膜受侵的敏感性、特异性和准确性分别为64%、89%和75%。CT对上颌窦侵犯的诊断特异性低，但敏感性高。结论：CT对上牙龈癌和硬腭癌侵犯上颌窦的判断有一定的价值。然而，上颌窦的侵犯应仔细考虑，因为CT表现提示上颌窦底破坏并不总是与窦侵犯一致。
Objectives: To clarify the diagnostic utility of CT in the evaluation of carcinoma of the maxillary gingiva and hard palate.Methods: The CT scans of 27 patients with squamous cell carcinoma of the upper gingiva and hard palate were reviewed, Tumor extent and bone destruction were compared with the surgical and histopathological findings to estimate the sensitivity, specificity and accuracy of CT.Results: The primary tumor was detected by CT in 89% of patients. The grade of bone destruction determined by CT correlated well with that verified at surgery or by histopathological examination. The sensitivity, specificity, and accuracy of CT for invasion to the buccal mucosa were 64%, 89% and 75% respectively. For maxillary sinus invasion, CT showed low specificity but high sensitivity. The accuracy was 86% when the criterion for sinus invasion was the presence of an enhanced mass continuous with the primary tumor.Conclusion: CT is helpful for the evaluation of tumor extent in the upper gingiva and hard palate carcinoma. However, invasion of the maxillary sinus should be considered carefully, because CT findings suggestive of destruction of the floor of the maxillary sinus are not always consistent with sinus invasion.
