Abstract

We observed a bilateral and symmetrical variation of the anterior belly of the digastric muscle during the dissection of a 35-year-old female cadaver. The accessory muscle bundles were arranged in a cross. These bundles were found superficial to the mylohyoid muscle and deep in the platysma. Such a variation from perfect symmetry has not been previously reported. To avoid misinterpretation of radiological tests, it is important to be aware of bilateral and symmetrical variations of the anterior belly of the digastric muscle when examining the floor of the mouth and the submental region.
