有关喉内淋巴管分布和吻合的研究报道较多 ,但尚有争议。酶组织化学染色法研究淋巴管细微分布比淋巴管间接注射法更客观 ,但应用该法研究喉内淋巴管分布的报道甚少。本文采用该法对喉内不同部位淋巴管细微分布进行观察。1　材料与方法1 .1　材料来源对 2 3例一侧喉腔未受肿瘤侵 There are still many reports on the distribution and anastomosis of the laryngeal tubes in the throat, but there is still controversy. Enzyme histochemical staining of lymphatic microlocalization is more objective than indirect lymphatic injection, but the application of this method to study the distribution of lymphatic vessels in the larynx is poorly understood. This article uses this method to observe the different distribution of lymphatic vessels in different parts of the throat. 1 Materials and Methods 1.1 The source of material on the side of the throat of 23 cases were not tumor invasion
