摘要
目的 :研究上下唇的血液供应 ,为新的组织瓣设计提供解剖学基础。方法 :对 10具从面动脉灌注红色乳胶的成年新鲜尸体标本的口周区域进行解剖研究 ,在 2具尸体标本的面静脉内注入兰色乳胶。在 3.5倍的手术放大镜下解剖显露血管。结果 :上唇动脉发出浅隔支与深隔支 ,向上走行进入鼻中隔前下部参与克氏动脉丛的组成。观察到 2种新的下唇动脉的分布情况。下唇动脉沿途发出唇颏支 ,与进入颏部的其它血管分支相互吻合。结论 :上下唇血供丰富 ,可设计含浅、深隔支的上唇岛状组织瓣、含鼻隔支的岛状鼻中隔软骨粘膜瓣及含颏唇支的垂直颏唇瓣 ;了解下唇动脉的解剖变异 ,对成功地施行一期下唇动脉岛状瓣手术是很重要的。
Objective: To study the blood suply of the lip region and develop new regional flap.Methods: Red latex was injected into the facial arteries at the lower jaw border on 10 fresh cadavers.On two of these cadavers, blue latex was injected additionally into the facial vein.The vascular anatomy of the lips was revealed by dissecting the vessels between the nasal alar base and a lower mental border (magnification ×3.5).Results: A septal branch and a nasal alar basal branch from the superior liabial arteries were confirmed.A vertical labiomental branch from the inferior liabial arteries was confirmed too.Two new patterns of vascular anatomy of the inferior lip were observed.Conclusions: There is adequate blood supply on the lip region.The mucosal arterial flap and cutaneous arterial flap of the upper lip and vertical labiomental arterial flap can be designed.And to know the anatomic variation of the inferior liabial arteries is very important for performing the one stage lower lip island arterial flap operation.
