What could be done to tighten and create a smoother neckline?
Sorry to hear about your problem. Stretch back of the skin and muscle can occur if the skin is not young and elastic. A secondary procedure is usually performed by the surgeon, should this occur, without a professional fee. Neck lift revisions happen in the best of hands, despite the comments from others, and I have seen the necessity of these from world famous neck surgeons. Often these may be performed under local. Picture the neck as a trampoline that has been bounced on and loosened in all directions. It may be best to tighten the platysma muscle and skin from all directions if it is loose: from above with a facelift, together with a corset, and backward with a neck skin excision.
You could definitely benefit from a Revision Neck lift. I recommend seeking out a Board Certified Plastic Surgeon to help you resolve your issues. If you would like to be seen by my office, feel free to reach out for a consultation. Smith Plastic Surgery 702-838-2455
