The digastric muscle is a suprahyoid muscle composed of two bellies connected by an intermediate tendon. This muscle participates in deglutition and mandibular movements. The anterior belly of the digastric muscle is localized superficially to the mylohyoid and deeply to the platysma muscle. During dissection of this region of an embedded cadaver, an accessory anterior belly of digastric muscle was observed bilaterally. The accessory bellies were similar but not symmetrical. They were composed of two segments, one long and one short, on both sides, and when observed together these appeared to form the letter “X”. The accessory fibers, on both sides, originated from the anterior digastric muscle and inserted medially to the digastric fossa. Anatomic variations of the digastric muscle may influence mastication and deglutition. Moreover, the accessory digastric muscle affects diagnostic imaging and therapeutic procedures in head and neck surgery and must be considered in procedures involving this area.
