I have a wide neck, what kinds of surgery might help me? (photo)

There are really just a few elements to be considered to treat a wide neck:  tightening loose skin, removing excess fat under the skin or even under platysma muscle, shaving down muscle thickness in the front, or even partial removal of a salivary gland.  There are pros and cons of each technique, and so the risk/benefit ration needs to be considered.  Your surgeon should be able to advise you at a personal consultation.  From your photo it doesn’t look like you have stretchy skin, but the deeper tissues can’t be adequately assessed from the photo.

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Unfortunately, even with best efforts it is impossible to see on this single photo what may be condition of your neck. I would recommend better set of photos that show your lower face and chin as well and/or, even better, in person evaluation bu an experienced board certified plastic surgeon. Good luck.
