ABSTRACT

We report two cases of anomalous digastricmuscles that were found during routine dissectionsof the submental region. Our firstcase was an 84-year old male cadaver who hadbilateral and symmetric accessory anterior belliesof the digastric muscle. A unilateral accessoryanterior belly of the digastric muscle withan accessory muscle bundle lying transversallybetween the two anterior bellies of a 60-year old male cadaver was observed in the second case. In the first case, the anterior bellies and accessory anterior bellies were attached to the mandible digastric fossa. In the second case, anterior bellies and an accessory anterior belly originated from the base of the chin and from digastric fossa and were fused at the beginning.It is important to be aware of possibleoccurrences of such anomalies during surgicalprocedures of the submental regio (AU)
