Abstract:
In some cases of double chin, the submental fold can become quite obvious. It can persist or even be deepended following a submental fatpad resection if the incision is made following the fold. The steps involved in eliminating this fold are: (1). A curved incision is made 1 cm in front of the fold. (2). The excess fat is reduced, leaving a 1 cm layer attached to the skin. (3). The fold is filled by sliding forward a fat flap taken from the fat remaining on the skin. (4). The sutures in the fat and the skin are not superimposed, to avoid recurrance of the fold.
