目的：探讨声门上喉癌隐性颈淋巴结转移对预后的影响。方法：回顾性分析129例声门上喉癌的病例资料，分组统计预后。结果：声门上喉癌颈淋巴结转移组与隐性颈淋巴结转移组二者预后无差异；N0病例中有无隐性颈淋巴结转移两组预后差异显著。结论：声门上喉癌隐性颈淋巴结转移影响预后，对声门上型喉癌N0病例应考虑选用分区性颈清扫术。
Objective: To investigate the effect of recessive cervical lymph node metastasis on the prognosis of supraglottic carcinoma. Methods: A retrospective analysis of 129 cases of supraglottic laryngeal cancer data, the prognosis of the subgroup. Results: There was no difference in the prognosis of supraglottic carcinoma between cervical lymph node metastasis and occult cervical lymph node metastasis. There was significant difference between the two groups in prognosis of N0 cases with or without cervical lymph node metastasis. CONCLUSION: The prognostic significance of recessive cervical lymph node metastasis in supraglottic laryngeal carcinoma should be considered in the case of N0 supraglottic laryngeal carcinoma. Regional neck dissection should be considered.
