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.
摘要
二腹肌前腹变异很大。前腹变异在颏下区变异中最为常见。在解剖的15具尸体中，我们观察到6例二腹肌前腹的此类变异（40%）。单侧和双侧变异的病例数相等。副肌腹常越过中线并附着于下颌舌骨肌上。了解此类变异在规划颏下区手术和肿瘤分期时具有重要意义。
