- Abstract
Introduction: Facial artery is the major artery to supply the major part of the face. Being a branch of external carotid artery, it arises at the carotid triangle of the neck above the greater cornua of the hyoid bone. Vascular variation is commonly observed during routine dissection in various parts of the body, especially in the face. The variations in the vascular pattern are mostly the variations in the branching pattern either arteries or veins. Hence, the present work is aimed to study in detail about facial artery anatomy in cadavers. Materials and Methods: The present study was carried out with dissection of 42 facial arteries in 21 faces of cadavers in the Department of Anatomy, Madras Medical College, Chennai. Results: The observation made in the present study among 42 facial artery dissection 30.95% showed double sublabial artery, 69.05% showed single branch of sublabial artery, and 5 sublabial arteries anastomosed with mental branch of the inferior alveolar artery. The incidence of sublabial artery is 30.9% and the average length of the sublabial artery is 2.95 cm. The superior labial artery arose in about 16.66% at the level of mouth, 71.43% were above and 11.91% were below the level of angle of mouth was observed. In addition, 95.24% of the septal branches were given by superior labial artery. Conclusion: The present study thus concluded that the vascular variation is common in the face due to varied branching and terminating pattern of facial artery. Prior knowledge of such variation in the vascular pattern of facial artery is utmost important in operative surgeries in congenital, traumatic, and oncological defects to avoid unintentional and serious complications.
