口腔颌面部恶性肿瘤颈部淋巴结阳性率分析

Analysis of Neck Lymphatic Metastasis of the Malignant Tumors in the Oral-Maxilloficial Region

口腔颌面部恶性肿瘤颈部淋巴结转移较为常见。颈部淋巴结根治性切除术在口腔颌面部恶性肿瘤的治疗中已广泛应用，对于减少术后复发、延长病人的生命有明显意义。本文通过对１５例根治性颈清扫术中淋巴结的检出数及阳性率进行分析，术中发现淋巴结１２０个，其中：颌下淋巴结４１个，颈深上淋巴结４４个，额部淋巴结２１个，颈深中淋巴结９个，颈深下淋巴结３个，颈后区淋巴结２个。病检阳性率依次为：颌下淋巴结１９．５１％（８／４１），颈深上淋巴结１１．３６％（５／４４）。并对根治性颈清扫术与功能性颈清扫术的适应证及利弊提出自己观点。

It is more common that neck lymphatic metastasis of malignant tumors in the oral rnaxilloficial region.In this article We analyze 1.5 cases,in whom 120 lymph nodes wete found. Among them 41 lymph nodes were discovered in the submaxillary regions 21 in the submental regionl 44 in the superior deep cetvical region;9 in the middle deep cervical region;3 in the inferior deep cervical region.The possitive incidence of lymph nodes in the sub maxillary region and superior deep eervial region is 19.5% (8/41) and 11.36 (5/44) respectively. The paper makes a new suggestion about RND(Radical Neck Dissection)and FND(Function Neck dissection).
