A MAC's lift helps the mid face and cheek area and some jowling. It does not help the neck. You have had a few procedures on your neck, and I think you need to be evaluated in person. Best of luck.
Based on the pictures posted and the complex history of at least two surgeries, You need in person evaluation and review of the operative notes of previous surgeries, then a plan of correction of the neck.
MACS facelift does not address neck bands. Excessive removal of fat from the submental area causes similar problems.
Be prepared for another surgery if you want correction of the neck. Botox to platysmal bands gets very variable results and is temporary
Thanks for your pictures- did you get a neck lift along with the MACs lift ? A neck lift is done through an incision under your chin. This is part of the same questions, when you said 'platysma muscle was cut' how was that done, what it done through an incision under your chin or just from the macs lift access ?
