The skin characteristics make the submental region an available flap site for facial and intraoral reconstructions. For this reason, the anatomy of the submental region and the submental artery (SA) has gained in importance recently. The SA branches out from the facial artery at the level of superior edge of the submandibular gland. The SA runs anteromedially below the mandible and superficial to the mylohyoid muscle. It gives off some perforating branches to the overlying platysma and underlying mylohyoid muscle during its course. The terminal branches continue toward the midline, crossing the anterior belly of digastric muscle either superficially or deep, and end at the mental region in general. Some perforating arteries from the terminal branches supply the anterior belly of digastric muscle. This study aimed to describe the anatomical features of the SA and its branches to help in the preparation of …
