What’s wrong with my neck? Which procedure can correct this? (Photo)

Jayhu- thanks for asking your question and photos. Based on these and your history there are several possibilities- the most likely for me would be something called a ranula - a cystic mass originating from a salivary bland in the floor of the mouth and protruding through the muscle of the neck- also possible to have something called a thyroglobulin duct cyst. More than a plastic surgeon I would strongly recommend scheduling an appointment with an otolaryngologist- head and neck surgeon (ENT). You need an exam and likely a CT scan- these are all typically benign but. An cause problems- once surgically removed your neck line (and the problem) will be better than ever!

Hi! To me this looks like you have a low positioned hyoid, which is what a lot of the muscles of your neck sling off of. This is especially obvious to me on the side view, although it is a little weird that it seems to stop right in the center. Have you had this scanned at all or has any doctor felt it? The change in positioning when you move your tongue around means that whatever it is is definitely in your deep floor of mouth region, so it could be deep fat under your platysma muscle.

In person exam is essential by appropriate Specialist. Diagnostic imaging (i.e MRI)- is needed in order to determine the diagnosis, after which time the appropriate treatment will be outlined.

I agree this is a very pronounced submental mass. I would recommend you go see your PCP and obtain some imaging of this area to better understand what this is.

You have large digastric muscles and glands. Many surgeons are reluctant to tackle these, but recent advances in instrumentation to remove these without bleeding have improved the technique. Check with board certified facial plastic surgeons in your area for this.

It is most likely just excess skin but there is a small possibility of a growth. There are certain growths seen in the neck such as thyroglossal duct cyst and salivary gland abnormalities. You should get checked by and Otolaryngologist to make sure none of those conditions exist. You might need an MRI as well. Once it has been determined that it is just excess skin/fat then you can have neck liposuction and Thermitight. Read below.
Chin Liposuction and Thermitight
Chin liposuction helps reduce the bulge under the chin and can be done for the whole neck. Once the fat is removed the skin can become loose and saggy in some cases. It can be avoided by combining it with Thermitight which is a radiofrequency heat delivered under the skin to tighten it. Both chin liposuction and Thermitight can be done at the same time. The recovery is fast and it can be done under local anesthesia.

Your neck presentation is very common and results from both fat above the muscle, and below the muscle in this region. Additionally, you have what appears to be sagging or ptotic submandibular glands. That said you would benefit greatly from a deep plane, neck lift with removal of extra fat above and below the muscle, as well as removing part of your submandibular gland plus or minus a small, chin implant.
