Thank you for your question. Unlikely as the chin does not numb very well, at least the bone area of interest. The problem is that once the incision is made, and the surgeon gets down to the bone, if you can't tolerate it, the options are to stop and go home, or use strapacaine, both not ideal options. You must be 100% positive you want to have changes to the bone, and there are many risks to consider. See a Board Certified Plastic Surgeon and or a Maxillofacial Surgeon and go over your options very closely. I hope this helps.
Any Doctors That Would Perform a Small Chin Reduction (Such As Burring of the Bone) Under Local Anesthesia?

Chin Reduction under Local Anesthesia
Small amounts of chin reduction can be done under local anesthesia infiltration with mental nerve blocks through either an intraoral or submental skin incision approach.
Chin bone reduction with Local Anesthetic
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.

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.
