✦ Synopsis

We describe a rare anomaly in the submental region of a single male cadaver specimen. The anterior belly of the right digastric muscle was observed to have three separate insertions. Most medial of these crossed the midline and inserted to the digastric fossa with the opposite digastric muscle. These muscle bands were united in a common tendon as they continued with the posterior belly. This is an anatomical variation in the mylohyoid digastric muscle group in the floor of the mouth. Consideration of such variations of the anterior bellies of the digastric muscles should be noted during the evaluation of the floor of the mouth in the CT examination or MR imaging.
