用聚氯乙烯铅丹动脉灌注，软Ｘ线造影的方法，对４０具（８０侧）儿童头部标本进行了上、下唇动脉的观察。上唇部的血供主要来自上唇动脉，该动脉具有出现率高，起始部位及走行较恒定的特点，其分支与主干垂直走行，根据两侧该动脉的分布范围可分为３型：即均衡型８０％，一侧优势型１２．５％和一侧代偿型７．５％。下唇部的血供除下唇动脉外，尚有颏下动脉。下唇动脉的特点是缺失率高，起始部位及走行不恒定，分支呈水平走行。根据下唇部血管的起始部位可分为６型。上、下唇动脉的这些特点将为临床应用提供参考。
The upper and lower lip arteries were observed in 40 (80 sides) children with arterial perfusion and soft X-ray angiography. The upper lip of the blood supply mainly from the upper lip artery, the artery has a high incidence, the starting position and walking more constant characteristics of its branches and trunk vertical walk according to the distribution of the two sides of the artery can be divided into three types: 80%, 12.5% on one side and 7.5% on one side. The lower lip of the blood supply in addition to the lower lip artery, there are submental arteries. Lower lip artery is characterized by a high rate of loss, the starting position and the line is not constant, the branches were horizontal walking. According to the initial part of the lower lip of the blood vessels can be divided into 6 types. These features of upper and lower lip arteries will provide reference for clinical application.
