摘要
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。
he superior and inferior lip
arteries were studied by means of molybdenum radiography on40
children cadaveric heads injected through the artery with polyvinyl
chloride and red lead. Thercsults show that the blood supply of the
superior lip comes mainly from the superior lip artery,which is
characterized by high incidence,constant commencement and course,and
vertical branch-es. Its distribution may be classified as three
types:the balanced(80%),the dominant(12. 5%)andthe compensatory(
7.5%).The blood supply of the inferior lip comes from hoth the
inferior lipartery and the chin artery. The inferior lip artery may
be abscent and is usually inconstant in ori-gin and course. Clinical
value of the characteristics of the superior and inferior lip
arteries is dis-cussed.
