Is this Cobra neck? What can be done to fix this? (Photo)

Thanks for your question! I would suggest reaching out to your plastic surgeon to discuss a possible revision to improve the contour. You could also get a second opinion to see what could be done. Good luck!

Thank you for your question. At 10 months the swelling from surgery should be gone and the contour is likely fairly stable. The goal of neck liposuction or direct fat excision is a smooth contour extending to the angle of the jaw and sternocleidomastoid muscle on either side. With contouring, you can get some unevenness as things heal for a variety of reasons.
I cannot speak specifically to your situation without an in person exam but some speculation can be made based on the photos and my personal experience treating neck fullness. It is also unclear from your submission what specific procedure you had that led to this result (direct excision, liposuction, fat dissolving injections or energy application with RF/laser, etc.). My comments are intended in a general sense and not as specific advice in your case.
Central depression can be due to excess fat removal in that zone or inadequate fat removal on either side. Often it is the combination of both. Excess fat removal can lead to tethering of the skin to the underlying muscle or central hollowing. Restoring volume with fat grafting can help although it often needs more that one session. Inadequate fat removal on either side can be dealt with by suctioning a bit more fat laterally and I did that for one of my own patients last year.
Some patients might also have contour problems due to thick digastric muscles or hanging submandibular glands. Neck anatomy is complex and optimal definition can require addressing the structures deep to the platysma muscle. Not all surgeons are comfortable with this zone as the risk of complications is higher.
For specific recommendations in your case, I would go back to the original surgeon and discuss the contour and how it might be improved. A second opinion with a respected board certified Plastic Surgeon in your area could be useful. You really need a proper exam and evaluation in person to diagnose the underlying issues and develop a safe and solid plan for smoothing area that out.
