Abstract
The omohyoid is an infrahyoid muscle with two bellies. It is responsible for
lowering and positioning of the hyoid bone. It is morphologically variable in
the origin, insertion and morphology of its bellies. Quantitative variations of the
superior belly of the omohyoid muscle are not common. We present a case of
a five-headed superior omohyoid, and a short clinical review related to this muscle.
All the bellies had their origin in an intermediate tendon and were attached to the
hyoid bone. The volume of its superior part was greater than usual. Knowledge
of the anatomy of this muscle is important, especially for surgeons operating in
the anterolateral neck region.
