Hello and thank you for your question. The best advice you can receive is from an in-person consultation. The only accurate way to assess for masseteric hypertrophy is with physical examination by your surgeon. If you do have hypertrophy, botox can be an effective treatment. Make sure you specifically look at before and after pictures of real patients who have had this surgery performed by your surgeon and evaluate their results. The most important aspect is to find a surgeon you are comfortable with. I recommend that you seek consultation with a qualified board-certified plastic surgeon who can evaluate you in person. Best wishes and good luck. Richard G. Reish, M.D. FACS Harvard-trained plastic surgeon
