Which is best for me, submentosplasty only, or submentoplasty + facelift? (Photo)

I'm a 58 year old women and about to commit to getting a procedure to lift my neck & lower face with a doctor whose recommending I get only a "sidelaze" and "submentoplasty." I'm concerned that this will not be enough to fix the problem. Should I be getting a facelift instead? I only want to do this once because scheduling downtime (away from work & socializing) is hard to do. Please help me decide what is best for me...go minimal or do full bore?
