Revision of corset platysmaplasty due to excessive tightness?

I feel my surgeon overtightened my neck lift in the center and laterally, especially on right side. I have severe tightness with choking feeling 11 mo post op and wonder if the platysma muscle was fixated to deep cervical fascia. After discussing multiple times with my double board certified PS, I have been told surgery was fine and not causing my symptoms. I disagree. Can the platysma muscle be released- cut to separate the front and release the sides? Any PS have experience w/this revision?
