I am 4 months post op from lower face and neck lift. When I look forward with my head raised my jawline looks perfectly smooth. If I smile, turn or lower my head I have terrible creasing and folds in my left jawline and lower cheek (see photo). My right side looks perfectly fine. My PS thinks this may be scar tissue and wants to undermine this area and under my chin again.
If this is scar tissue, why does this happen? What's to prevent this from reoccuring with a revision? How long should I wait for revision surgery?
