First you have to exclude goiter as a reason for neck deformity. If deformity is caused by fat deposits in your neck (which may be a family trait) simple liposuction in local anesthesia will help.
You need a consult with endocrynologist and when your thyroid enlargement is ruled out consult a board certified plastic surgeon to discuss neck contouring options. Good luck.
Thank you for your question and photos. There are several options that wile of help. From minimally invasive perspective Kybella is an excellent option. Its an enzyme injected into the central neck to treat submental fat. Often two treatments are required but this can be an excellent option. From the surgical camp submental liposuction is a great method to remove fat and contour the neck and jawline. The procedure can be done under local anesthesia with a predictable result and very expeditious recoveryBest of LuckDrG
This needs VASER/ThermiRF to get the most contouring and reduction in fat. Non invasive is an alternative but will do very little and take many treatments. Best, Dr. Emer
Your photos indicate a classic goiter. You need to see a general surgeon.
Thank you for your question. You should see a surgeon who can perform computer imaging for you. That way you can see what is realistic. There are nonsurgical and surgical options for you. A profile picture is necessary to give an accurate opinion. That said, if you only have excess fat, Kybella injections can help. If you have excess tissue, fat , and muscular decent, liposuction and a platysmaplasty are options.Best wishes.
Liposuction under the chin is an effective and long lasting remedy with predictable results for diet and exercise genetic deposits of fat that are difficult to lose otherwise.
