Abstract
The digastric muscle, as the landmark in head and neck surgery, has two bellies, of which various variations have been
reported. In the submental region of a 72-year-old Korean male cadaver, bilateral variations were found in the anterior belly
of the digastric muscle. Two accessory bellies, medial to the two normal anterior bellies of the digastric muscle, ran posterior
and medially, merging and attaching at the mylohyoid raphe of the mylohyoid muscle. The 3rd accessory belly originated from
the right intermediate tendon and ran horizontally, merging the right lower bundle of the right accessory belly and inserted
together. These accessory bellies had no connection with the left anterior belly. This unique variation has not been reported in
the literature previously, and this presentation will guide clinicians during surgical interventions and radiological diagnoses.
Key words: Digastric muscle, Anterior belly, Variation
