Abstract

Abstract: The facial artery is the main artery of the face and variations in its origin and its branching pattern have been documented. We report herein multiple facial artery branch variations in the face. A large posterior (premasseteric) branch originated from the left facial artery and coursed upwards behind the main trunk of the facial artery. This artery presented with a straight course and was closely related to the anterior border of the masseter. The branch then terminated by supplying the adjacent connective tissue below the parotid duct. It was also observed that the facial artery was very thick and tortuous and terminated as the superior labial artery. Knowledge of this variation is of great clinical significance in facial operations, especially for maxillofacial surgeons and plastic surgeons, because it forms the anatomical basis for the facial artery musculo-mucosal flap.

Resumo

Resumo: A artéria facial é a principal artéria da face, e variações da sua origem e padrão de ramificação têm sido documentadas. Este artigo descreve múltiplas variações de ramificações da artéria facial. Um ramo posterior grande (pré-massetérico) teve origem na artéria facial esquerda e cursou para cima por trás do tronco principal da artéria facial. Essa artéria apresentou um curso reto e intimamente relacionado com a borda anterior do masseter. O ramo terminou suprindo o tecido conjuntivo adjacente abaixo do ducto parotídeo. Também se observou que a artéria facial tinha grande calibre, era tortuosa e terminava na artéria labial superior. Conhecer essa variação é de grande significância clínica em cirurgias da face, principalmente para cirurgiões maxilofaciais e plásticos, tendo em vista que ela forma a base anatômica para o retalho músculo-mucoso da artéria facial.
