Anatomy of the arterial vascularization of the lips.
The findings from 12 dissections of previously injected facial masks, 8 dissections of the face following intraarterial injection of a red solution of Latex Neoprene, and a corrosion cast specimen allowed us to study the arterial supply of the lips. The arterial supply of the upper lip arises mainly from the superior labial arteries, but also from the subseptal arteries and from the subalar arteries. There is a figure of 8 shaped anastomotic system between these arteries lying on the upper lip. The arterial supply of the lower lip arises from the inferior labial arteries and from branches of the mental artery. A constant inferior labial arterial network was shown at the level of the lower lip arising in a fifth of cases from a T-shaped inferior labial artery. All these recent anatomic findings help us to improve our understanding of plastic surgery of the lips.
