The lymph drainage of lower lip mucosa was studied in 30 fresh cadavers of fetus and neonatus by submucosa injection of 30% Prussian blue of chloroform solution. The collecting lymphatics in lateral third of both the right and left sides of the lower lip mucosa ran laterally to the angles of the mouth, and then back- and downward between mandible and depressor muscle of angle of mouth, and finally, accompanying the facial vessels, emptied into submandibular lymph nodes. The efferent lymphatics of the latter emptied into angular lymph nodes and jugulo-omohyoid lymph nodes. The collecting lymphatics in the middle third of the lower lip mucosa went superficially to the mental muscle and downward into submental lymph nodes. The efferent lymphatic of the latter emptied, anteriorly to the body of the hyoid bone, latter- and downward into right and left jugulo-omohyoid lymph nodes. All collecting lymphatics lie in the loose connective tissue between the muscles.
采用30%普鲁士蓝氯仿溶液黏膜下注射法，对30例新鲜胎儿及新生儿尸体的下唇黏膜淋巴引流进行了研究。下唇黏膜左右两侧外1/3的集合淋巴管横向走行至口角，然后在下颌骨与口角降肌之间向后下方走行，最后伴随面血管注入下颌下淋巴结。下颌下淋巴结的输出淋巴管注入角淋巴结和颈内静脉肩胛舌骨肌淋巴结。下唇黏膜中1/3的集合淋巴管浅行至颏肌，向下注入颏下淋巴结。颏下淋巴结的输出淋巴管在舌骨体前方、向后下方注入左右颈内静脉肩胛舌骨肌淋巴结。所有集合淋巴管均位于肌间疏松结缔组织内。
