The Study of Higher Origin of Facial Artery and its Surgical Significance

Facial artery plays a key role in blood supply of the face. Facial artery one of the anterior branches of the external carotid artery originates within the carotid triangle. Variation in the origin of the facial artery was observed on two sides out of 60 sides in 30 cadavers. Facial artery was observed originating at the level just below the maxillary artery within the parotid gland. Facial artery may originate as linguo-facial trunk or thyro-linguo-facial trunk. Other developmental variations have also been described in the literature like, agenesis of facial artery, enlarged facial artery, hypoplastic facial artery. Variability in situation may complicate the surgery. Therefore maxillofacial surgeon, plastic surgeons and head & neck surgeon should be aware of such variation.
