Technically any facial surgery procedure can be performed under local anesthetic. The reality of it is that the procedure would be quicker and safer if performed under a sedation. The other aspect of your question is "butting of the bone"... I'm not quite sure what you mean by that but reduction of chin typically is performed by making a cut "osteotomies" into the chin portion of your lower jaw. Once freed up the chin is repositioned into the desired new position and fixated with titanium plates and screws Hope this helps. dr m
Certainly that is a possible approach if you are comfortable with the 'idea' and not overly nervous. You would feel 'pulling' and vibrations, but it is not a difficult procedure.
