The best way to avoid the "noose-like" sensation following a platysmaplasty?

Well,
I advise patients that this tight sensation is a reflection of the tightening
of the upper neckline muscles. It can be avoided, but of course means
less of an elevation/tightening of the platysma. which means a less impressive
improvement. You need to discuss this with your surgeon.

Tightness of the neck is desirable in the first week or so after neck lift because the tissues always relax and if you do not feel tight in the beginning your result will be compromised and the neck will re-sag and the platysma bands reappear.However it is a general feeling of tightness and does not feel like a Noose.There is however a suture method that uses a permanent suspension suture placed from the ear to ear across the neck, often called the Giampappa suture or neck suspension suture which can create thisNoose like feeling.  Ask your surgeon not to use this suture.

Unfortunately there is no way to completely avoid a tight feeling after a necklift.  It is a necessary step in correcting neck contour.  It usually improves with as the swelling resolves.  It will not compromise your breathing or swallowing.  You may need some assistance in managing your anxiety during your recovery. Best wishes.
