The facial artery is an important branch of the external carotid artery, which starts at about the angle of the flat mandible, passes forward through the deep surface of the submandibular gland, bypasses the lower edge of the mandible at the anterior edge of the stopping point of the occlusal muscle, reaches the face, and meanders up along the lateral side of the corner of the mouth and the nose to the medial canthus.8 Therefore, the facial artery is also known as the medial canthal artery. The branches of the facial artery are mainly distributed in the submandibular glands, face and palatine tonsils, etc., and are used to supply the blood supply to the submandibular glands, face and palatine tonsils, etc. The facial artery is superficially located at the anterior border of the occlusal muscle around the lower border of the mandible, and its pulsation can be palpated in vivo, where it should be compressed to stop bleeding when the face bleeds to avoid further hemorrhage.
