Neck Lift vs Platysmaplasty Surgery. Is it possible platysmaplasty can be done without any incision under the chin?

Thank you for your question.  A platysmaplasty is usually approached through a very small (~2 cm) incision that is hidden in one of your natural skin creases on the underside of your chin.  This incision usually heals very nicely and is barely perceptible since it is hidden within a natural skin fold and under your chin.  The incisions for a neck lift, as you mentioned, does require incisions behind your ear but these also are hidden within creases and hairlines as well.  Not all patients need a platysmaplasty - only if they have muscle bands that need to be treated.  We understand the importance of hiding incisions and scars and strive to keep them discreet.  I hope this helps! 

A neck lift is a set
of procedures that can tighten the neck skin and muscle in an effort to remove
excess skin and restore better contour to the neck. The extent of the procedure
is tailored to the needs of each patient but often involves neck liposuction or
direct fat excision, tightening of the underlying neck muscle (cervicoplasty or
platysmaplasty), and skin tightening and excision. There are often three
incisions: 1 around each ear and 1 under the chin. The incisions around the ears
are used to dissect the skin free of the underlying muscle, to access the
lateral part of the muscle (the platysma) for tightening, and to tighten and
remove the excess skin at closure. The sub mental incision (under the chin) is
used to remove excess fat from the neck and to tighten the central part of the platysma.
Without the sub mental incision, the surgeon does not have the ability to
easily remove the fat from central portion of the neck or to tighten the
central part of the platysma. This incision may not be needed for some
patients, however, for others it will compromise the extent and / or longevity
of the lift. A detailed examination will help delineate the best
surgical treatment. Consultation with a plastic surgeon would be the next best
step.

Without seeing pictures or examining you, it is very difficult to give you specific advice.  A neck lift without a platysmaplasty tightens the skin, but does not address the muscles.  In most cases, the platysmaplasty is recommended to achieve the best result.  However, each patient is addressed separately and the best procedure advised to the patient.  A small incision under the chin leads to a significantly defined neck and jaw line in most patients.Good Luck
