Facial rejuvenation by neovascularization and a proliferation of fibroblasts. In this region, fat deposits are primarily subcuataneous. Submental and submandibular fat pads lie between dermis and superficial cervical fascia overlying the platysma muscle. This plane is devoid of any important vascular or nervous structures and is safe for suction lipectomy. Platysma is a broad flat muscle inserting into subclavicular and acromial areas.
Fibers cross in lower protion of the neck and terminate at inferior border of mandible.
The platysma may be totally separated along the submental region. Distinct inferior border of mandible. Stab incision just posterior to the submental crease and at retromandibular regions Infiltration of tumescent solution.
