喉内外淋巴管间的吻合

The Anastomosis between Lymphatics of Laryn and Surrounding Organs

目的 了解喉内淋巴管与喉邻近器官淋巴管之间的关系。方法 利用 2 2具胎儿和婴儿尸体的喉标本 ,30 %普鲁士兰氯仿液 ,淋巴管间接注射法 ,显微镜观察。结论 会厌舌面与舌根部淋巴管、喉内与喉咽部淋巴管以及声门下区与气管上段淋巴管之间存在吻合。结果 由于喉内、外淋巴管间存在吻合 ,临床手术中应充分考虑这一特点。并提出了肿瘤侵及会厌舌面 ,杓会厌皱襞和声门下区的手术切除范围。

The relationship between laryngeal lymphatics and the lymphatics of surrounding organs was studied. Methods: Twenty two fresh dead fetuses and babies were studied by indirect lymphatics injection technique(30% Prussian blue) and observed under light microscope. Result: There were lymphatic anastomosis between lingual surface of the epiglotts and root of the tongue, the, The infraglottic region and cervical portion of the trachea. Conclusions: Because the internal and external lymphatics of larynx were anastomized each other, when cancer invades lingual surface of the epiglottis, the arytenoid region or the infraglottic region, therefore the root of the tongue, the pyriform sinux or the cervical portion of the trachea should be excised respectively.
