Abstract:
The anterior belly of diagastric is highly variable. Variation in anterior belly is most common amongst the submental region variations. We observed 6 such variations in the anterior belly of diagastric among 15 cadavers dissected (40%). Unilateral and bilateral variations were seen in equal number of cases. Accessory belly frequently cross midline and attached over the mylohyoid muscle. Knowledge of such variations is of significant importance while planning for surgeries in submental region and during staging of tumors.
