Submental area rejuvenation by digastric corset: anatomical study and clinical application in 20 cases.

Unlabelled: Knowing the difficulties and limitations of surgery for rejuvenating the submental area during a cervicofacial rhytidectomy, we came up with the concept of the digastric corset, which is described in this article along with the surgical importance of the platysma, digastric and mylohyoid muscles based on anatomical dissections. A study of ten cadavers was conducted to describe precisely the limits of the submental area, the mandibular edge between the two Furnas ligaments, and the hyoid bone. Each anatomical item was dissected plane by plane: the skin, platysma, digastrics muscles, and mylohyoid muscle.
