What is platysmaplasty and sub mental liposuction

Platysmaplasty is the suturing of the neck "band" muscles together. This is done with a small incision beneath the chin that hides beautifully. The result is typically lifting of the neck area to a modest extent, depending on how much skin excess there is. With lots of skin, particularly sun-damaged skin that is thin and has lines, it is difficult to get much of a result without some type of facelifting. Submental liposuction (removal of fat through a small instrument called a cannula, via a very small 3mm incision)  can be done alone or together with platysmaplasty, depending on your individual anatomy. If you only have fullness of a little bit of excess adipose tissue in the neck, and you have youthful skin, liposuction alone can provide a beautiful result. It also complements platysmaplasty quite well, further defining the neck result. Hope that helps! Dr. Donath 

Submental liposuction/liposculpting is performed by making an incision under the chin (in the natural crease) and removing the fat between the skin and underlying muscle (platysma).  This fat removal can be performed either by a liposuction cannula (straw-like tube), by direct excision of fat, or by a combination of both.  Although rare, a surgeon may remove additional fat deep to the platysma muscle (subplatysmal fat) if he/she feels it is necessary to obtain better results.A platysmaplasty, by definition, is anything that is surgically done to the platysma muscle that alters its anatomy. Most commonly, prominent platysmal bands (ie cords) and sewn together to remove the bands and increase the angle and definition under ones chin.  Other times the platysma muscle (or bands) can be cut/injured so that they are not as strong/prominent.  When this is performed under the chin, this is technically called a "medial" platysmaplasty. Any manipulation of the platysma from the sides (ie around the ears) would be considered a "lateral" platysmaplasty.  

Platysmaplasty-  It is a surgical procedure that creates angulation of the neckline below the chin from the profile by tying the right and left platysma muslces together in the middle.  The platsma muscle is a long thn muscle that goes from the jawbone to the clavicle.  The muscle do not meet in the middle.  During a plastysmaplasty, these muscle are stitched together to tighten the neck.  Sub Mental Liposuction-  It is a surgical procedure where excess fat in the neck is remove by negative pressure suction attached to cannulas with holes.  It will define the neck and jawline by removing excess fat and causing the skin to tighten overtime.
