Does this look like a cobra neck or something else? (Photos)

I am sorry that you are so unhappy. Overall your neck looks very good but I definitely see the residual platysmal banding that bothers you. This can be improved with a central neck plication that can be performed in the office setting. Botox can also be utilized to improve the banding but this is more temporary. Good luck!

Thank you for your questions and pictures.  In your pictures it seems that you need tightening of the platysma muscle (also known as platysmaplasty) will require a small incision under the chin away from direct view to gain access to the front edge of the muscles on the neck; they are sutured together with permanent stitches. The muscles of the neck are the foundations and building blocks of the neck and are fundamental to achieving a tight and toned result.  Please make sure you find a reputable and qualified plastic surgeon who can assess you properly to give you a realistic idea of what outcome you can achieve.  All The Best 

This is not a cobra head deformity.  That occurs when surgeons aggressive remove subplatysmal fat from the central neck.  These are simply platysmal bands that did not get addressed with your facelift. Did your surgeon perform central neck work?  Some do not.  This is best addressed with a midline plastysmaplasty.  That can be done as an isolated procedure or as part of a more extensive revisional facelift.  Lasering the neck skin is not fixing this.  While saying building collagen may sound good, it will not in anyway address your concerns.
