What is the difference between turkey neck and a double chin?

Interesting question- my take on this is that a 'turkey neck' is from excess skin and muscle that you frequently see in patients 65 and older (look at my website, there are a few in their late 60's/70's with turkey necks). A double chin can be seen in younger patients and is due to extra fat under the skin causing a bulge, it does not necessarily have any extra skin yet. In the younger patients with a double chin, simple liposuction can do the trick to contour the neck- turkey necks usually require some combination of liposuction and removal of extra skin with or without muscle tightening. 

  Double chin and turkey neck are basically the same thing  and are just  a description for  an unflattering neck. Some patients have fatty deposits located above and below the platysma muscle, neck cords present, and loose skin in the neck. A neck lift procedure is performed on patient's less than 50 years of age who require fatty deposit removal and a platysma plasty. When there is excess skin present in the neck, a lower face and neck lift is performed. The goal of a lower face and neck lift is to tighten loose facial and neck skin,   tighten loose facial and neck muscles, and remove the fatty deposits causing the turkey neck and double chin.  For many examples of both procedures, please see the link and video below
