67, male - persistent lumps appear after neck lift & revision (Photos)

Usually direct excision of this tissue should do the trick. Sometimes, excision and then elevating and re-tighening the skin is needed.

This is a cobra neck deformity. This is related to excessive removal of the deep fat in between the platysma muscle bellies in the midline of the neck followed by dehiscence (separation) of the two platysmal muscle bellies from the midline repair. The fullness in the midline could be residual submandibular glands or deep fat (below the muscle). It does not appear that the submandibular glands were adequately reduced. It also appears that the platysma muscle has separated and there is now a gap out of the midline. I would recommend a deep plane neck lift to reduce the deeper fat further, sculpt the submandibular glands, repair the platysmal muscle bellies back together and very carefully perform superficial fat liposuction. There may also need to do some superficial liposuction of the fat immediately below the skin needs to be very conservative as this fat is critical to having smooth, shiny and normal looking skin. You need to find an American Board of Plastic Surgery certified surgeon; ideally, this surgeon has also completed an aesthetic fellowship accredited by the Aesthetic Society.

This looks like either residual skin excess or scar tissue that has built up in the area under your chin. I would recommend a series of steroid shots (Kenalog) along with massage and possibly also microneedling to help. This can be a tough problem to fix but there is hope as I have seen this quite a few times in my 21 year career. Hope that helps!
