颈淋巴清扫术是治疗口腔颌面部恶性肿瘤的重要手段。但是,由于口腔颌面部恶性肿瘤的颈淋巴结转移的早期诊断问题目前仍未解决,以至选择性淋巴清扫术的误选率仍较高。因此,努力提高诊断颈淋巴结转移的准确率仍然是摆在我们面前的重要课题。关于口腔磷癌淋巴结转移的预测问题,Shear于1976年就提出了“转移机率”预测法,并根据转移机率再决定是否应作预防性清扫术。本文就我科25年 Neck dissection is an important method for the treatment of oral and maxillofacial malignancies. However, the early diagnosis of cervical lymph node metastases in oral and maxillofacial malignancies remains unresolved, and the rate of misselection in selective lymphadenectomy is still high. Therefore, efforts to improve the accuracy of the diagnosis of cervical lymph node metastasis is still an important issue before us. Regarding the prediction of lymph node metastasis in oral phosphorus cancer, Shear proposed the “transition rate” prediction method in 1976, and based on the probability of transfer, he decided whether to perform preventive cleaning.
