[Submental region in young adults].

Techniques of correction of thickening of the submental region are based on an anatomical analysis: position of the hyoid bone, mental protrusion, supra- or sub-platysmal steatomery, anatomy of the platysma muscle. Defatting procedures can be performed with an aspiration cannula, but a musculoplasty is sometimes required. Only direct exploration allows modelling of the fat situated between the platysma and the floor of the mouth.
