A rare case of a muscle described as a sphincter colli profundus has been reported. This muscle sheet arose deep to platysma from the medial part of the clavicle and inserted into the fascia of the pinna. In this particular case, platysma was reduced in size and supraclavicularis and mandibulomarginalis muscles were present.
Syn.: m. subcutaneus colli, platysma myoides, quadratus genae (Cowper), latissimus colli (Albin), Breiter Halsmuskel, Hauthalsnmuskel, Le peaucier (Winslow).
