Is there an option to shave the chin, does the bone grow back after this procedure?

Yes, chin reduction is certainly possible.  For most patients I will also have to taper the reduction a little further back into the jaw bone as well to avoid the appearance of an overly square chin.  No plates or screws are involved (though when used in the jaw for other procedures plates and screws are very safe).  We will often modify a patient's own photos to give them an idea of what kind of change can reliably be achieved.  Look for a surgeon who performs this surgery regularly and have them show you exactly what can reasonably be changed.  -Dr. Rolfes

Thanks for your question. A chin reduction/witches chin correction can help to soften the appearance of a prominent chin. If your large chin is caused by soft tissue, bone or both that will determine the surgical approach. I recommend an in person consultation with a board certified plastic surgeon and hyperesthetic facial specialist to determine best individual surgical plan.

It is absolutely possible to contour the jaw without plates or screws. I do this through incisions inside the mouth and sculpt the bone with a powered rasp. The worst part about recovery is swelling of the masseter muscle which could last as much as several months but gradually goes down each week. Expect to take about a week off of work. 
Best of luck to you,
