What is the Best Revision /correction for Treating a Cobra Neck Deformity?

This deformity classically presents with hollowness under the chin and remaining fullness to either side. My treatment varies by the particular situation but usually relies on fat grafting to the area of hollowness. In addition, redundant fat on the sides plus lifting of remaining loose platysma bands provides a good balancing of the neck with a smoother contour.

I am sorry to read of your disappointment. It would be helpful to know more about the surgical techniques applied during the procedures as you may benefit from additional surgery to better correct your concern. Nevertheless, it's best to wait at least 6 to 12 months depending on the reason for a #revision.It would be best to consult with a board-certified surgeon in-person as you may have more than one option. The presence of banding down the front of the #neck, and, amount of excess skin and condition of your skin are among some factors which determine if you are a #candidate for #rejuvenating the neck. Chin deficiency with the neck and jawline are also taken into consideration. A weak #chin implies a lack of chin support for the skin along the neck line. As a stand-alone procedure, chin augmentation can be performed in the office under local #anesthesia. For individuals with signs of aging in the neck, a chin implant added to one of the recommended procedures above, will provide optimal results.Also, your procedure should always be performed by a #PlasticSurgeon who is board-certified and has a great deal of experience specializing in cosmetic #surgery and #neck lifts. Additionally, you should feel confident and comfortable with the doctor you choose. Whether it is the same doctor who did your original surgery, or, you feel it necessary to seek a new one. As with all #cosmetic surgery, results will be rewarding if expectations are realistic. With any surgical #procedure and #revision, there are some risks of unhappy outcome or other complications which your surgeon should discuss with you during your consultation. You will then greatly improve your chances of getting the result you desire, and, without the need for additional revision surgery.

This is a difficult problem but can be improved by all the techniques you mentioned.  I have used fat grafting with some success as well as undermining and advancement of the medial platysmal borders
