ARAVENA TORRES, Pedro et al. Biomethrics Study of the Upper and Lower Labial Artery in Human Cadavers. Int. J. Morphol. [online]. 2008, vol.26, n.3, pp.573-576. ISSN 0717-9502.

The face is richly vascularizad by various branches of the facial artery. Among them are the upper and lower lips branches irrigate the lips and cheeks. The purpose of this study was to analyze the biometric characteristics of labials arteries of human corses . It disected 18 human midfaces, preserved on the basis of formalin and the arterial system repleted with red latex. It noted the trail of the facial artery and the presence of the upper and lower labial arteries. Anatomical fixed points were established to measure the distribution pattern of facial artery in the facial region and the origin and route of the upper and lower labial arteries. Of the 18 analyzed samples, 100% labial arteries presented an independent origin of the artery facial with an average distance 36.61mm (SD 8.51) between them. The upper labial artery originated on the oral angle and lower labial artery basilar closest to the edge of the jaw. The values obtained reported a wide variation in the origin and behavior of the upper and lower labial artery.
