目的 :探讨上颌恶性肿瘤中间区淋巴转移的检测手段。方法 :采用伊索显 - 3 0 0对 14例上颌恶性肿瘤进行间接淋巴造影 ,通过CT检查淋巴显影情况。结果 :7例咽后咽旁淋巴结受累者 ,毛细淋巴管粗糙、狭窄 ;淋巴结体积增大 ,形态不规则 ,边缘缺损呈虫蚀状改变。结论 :该方法切实可行 ,有助于对中间区淋巴转移的诊断和治疗
Objective: To investigate the detection of lymphatic metastasis in the maxillary malignant tumor. Methods: Indoximax-300 was used in indirect lymphadenectomy on 14 cases of maxillary malignant tumor. Lymph imaging was examined by CT. Results: In 7 cases with involvement of parapharyngeal parapharynx, the lymphatic capillaries became rough and stenotic. The lymph nodes increased in size and irregular in shape. Conclusion: This method is feasible and helpful for the diagnosis and treatment of lymphatic metastasis in the middle area
