Bilateral anatomical anomaly of anterior bellies of digastric muscles.
During the gross anatomy dissection of the submandibular region, both anterior bellies of the digastric muscles, especially the left one, were found to be enlarged. They were arranged as two parallel asymmetric bands extending from the hyoid bone to the chin. The posterior bellies of the digastric muscles were normal. The suprahyoid muscles showed no abnormalities. This anomaly represents an anatomical variation in the mylohyoid digastric muscle group in the floor of the mouth.
