Abstract
The digastric muscle has two bellies and it has various variation in
submental region. During dissection of a 79-year-old Korean female
cadaver, bilateral variations at the anterior belly (AB) of the digastric
muscle in submental region were shown. Two accessory bellies originated
medial to the origin of the two normal ABs of the digastric muscle. They
run medially and combined each other anterior to the median raphe of the
mylohyoid muscle. In left side, AB of the digastric muscle was divided
into two muscular bellies. Therefore, five bellies of ABs of the digastric
muscle were found. This novel variation has not been described in the
literature and this appearance will guide clinicians during surgical
interventions and radiological diagnosis.
