I had a necklift with platysma 6 months ago. There are 2 "pouches" under my chin. Should I have a revision? (Photo)

It is possible that it may be some persistent skin, skin and muscle or skin, muscle and fat. From the limited views it does not appear to be your submandibular glands since it is too far toward the front of your neck. It may also be that too much fat was removed directly under the chin. In either case, it is not uncommon to require a revision in that area called a submentoplasty and often corrective procedures help that area. Good luck with your procedure.

I've seen this before in revisions from other surgeons. Revision is appropriate at this point. The swelling is due to how the platsyma reacted to different pulls from surgery. Wide skin elevation is recommended to visualize the muscle. Defatting of the area is recomended. Lateral muscle pull alone will not likely resolve the problem. It might also be due to thick muscle or fat under the muscle.  I would approach the muscle medially to see what's going on. There's no reason it couldn't be done under local. I do wide dissection all the time under local. Your doctor just has to be comfortable doing it that way. It seems reasonable that there may not be much skin to tighten.

I have to ask was the surgeon a boarded Plastic Surgeon? Appears there are many issues that can only be explained in an IN PERSON evaluation.
