What's the difference between chin liposuction and neck lift?

Liposuction of the fat beneath the chin is a fairly minor procedure that uses small incisions to remove fat above the platysma muscle. It is useful if there is fat but minimal excess skin.  In my practice, a neck lift is a more extensive surgery performed for excess skin in the neck.  A neck lift involves skin undermining and excision of skin, and tightening of the platysma muscle, often through incisions beneath the chin and sometimes also in front of the ear.  Depending on the needs of the patient, it may also include fat removal under direct vision during the surgery.  

Thank you for sharing your question.  Liposuction is a procedure aimed at reducing the amount of fat present along the jawline and “double-chin” region alone.  This is not the procedure for skin excess, laxity, or muscle separation. In this case a necklift is employed for the best outcome.  Hope this helps.
