What could fix my neck lift deformity?

Thank you for your question. You need a revision of your surgery. That condition is not going to get any better.   You need to exposed al the neck structures and revised your platysma muscle and the fat compartments in the neck and face area

This is a cobra deformity and needs aneck lift reconstruction. I suggest seeing an expert in facial surgery our office has a reconstructive facial surgeon.  Best, Dr. Emer.

this is the deformity seen when an excessive amount of fat is removed from the midline of the neck without removing tissue to the sides. The tissues that need to be removed are the submandibular glands and perhaps some of the digastric muscle. There are several prominent facelift surgeons in SF who do this. look on the internet for submandibular gland removal.
