根据３６例腮腺恶性肿瘤临床资料，评价了ＣＴ扫描对腮腺恶性肿瘤ＴＮＭ分期的价值，并详细分析了ＣＴ扫扬对准确和量原发灶大小及判断颈淋巴结有无肿瘤转移的情况，着重讨论了颈淋巴转移的ＣＴ诊所标准，与术后病理结果相对照，得出触诊法对预淋巴转移诊断准确率为６９．４％，ＣＴ扫标的诊断准确率为８０．６％．比较ＣＴ扫出前后３６例腮腺恶性肿瘤ＴＮＭ分期情况，其分期变００率为３３．３％．表明ＣＴ扫描提高了对腮腺恶性肿瘤诊断分期的准确率，为确定手术方案及判断预后提供更科学的依据． Based on the clinical data of 36 patients with parotid malignancies, we evaluated the value of CT scan in the TNM staging of parotid malignancies, and analyzed in detail the accuracy of the CT scan and the size of the primary tumor, as well as the presence or absence of tumor metastasis in the cervical lymph nodes The CT clinic criteria for cervical lymphatic metastasis were compared with postoperative pathological results. The accuracy of palpation was 69.4% for palpation and 80.6% for CT scan. The TNM staging of 36 parotid malignant tumors was compared before and after CT scan. The staging 00 rate was 33.3%. It shows that CT scan improves the accuracy of the diagnosis of parotid malignancies staging, to provide a more scientific basis for determining the surgical plan and prognosis.
