Abstract

Anterior belly of the digastric muscle usually arises from the digastric fossa of the mandible and the posterior belly of the digastric usually arises from the mastoid notch of the temporal bone. In the present case we came across an accessory muscle medial to the anterior belly of the digastric in the left suprahyoid region. The accessory muscle took origin from the digastric fossa and also from the lower border of body of the mandible. The anterior belly took origin from the mandibular fossa, lateral to the accessory muscle. We also noted that the accessory muscle inserted partly into the hyoid bone and a few fibers inserted into the intermediate tendon. The fibers from the anterior belly of digastric muscle inserted into the intermediate tendon. This variation was observed unilaterally in the left half of the suprahyoid region.
