目的探讨声门上型喉癌颈淋巴结隐匿性转移的病理特点和规律，帮助临床治疗。方法对100例临床N0的声门上型喉癌患者和颈廓清标本（153侧）进行连续切片，光镜观察。结果隐匿性转移率为38%。发现转移淋巴结51个:Ⅰ区1个（2％）、Ⅱ区37个（73％）、Ⅲ区12个（23％）、Ⅳ区1个（2％）。转移淋巴结的长径0.5-2.6?cm，平均为1.1?cm。51个淋巴结中，癌早期21个（41％)、癌长期18个（35％）、癌满期7个（14 ％）、破膜期5个（10％）。结论声门上型喉癌颈淋巴结的隐匿性转移率高，早期不易诊断，应积极行选择性颈廓清术。

Objective　To study the pathologic features of occult lymphatic metastasis in supraglottic carcinoma.Methods　Serial sections of 153 neck dissection specimens in 100 patients with supraglottic carcinoma were evaluated under the microspcope.Results　In 100 patients, 38 had occult metastatic lymph nodes. 51 metastatic lymph nodes were found in pathology, and their sizes ranged from 0.5?cm to 2.6?cm (average 1.1?cm). The distribution of 51 lymph nodes was 1 in level Ⅰ (2%), 37 in level Ⅱ (73%), 12 in level Ⅲ (24%), and 1 in level Ⅳ (2%). Among the 51 nodes, 21 (41%) were early stage, 18 (35%) were growth stage, 7 (14%) were tull stage, and 5 (10%) were extracapsular stage. The differentiation degree and appearance of supraglottic carcinoma was not directly related with occult metastasis.Conclusion　The occult metastatic rate of supraglottic carcinoma is high, and selective neck dissection may be necessary.
