The great majority of surgeons asked to reduce masseteric hypertrophy will recommend Botox. This is for two reasons.First, it can potentially be a nonsurgical, relatively risk-free solution to your problem. The downside is to need for repeat treatments.Second, surgical masseteric reduction is very uncommonly performed. Not only are very few surgeons trained and comfortable in doing this, but carries risks with it such as damage to some of the nerves which control the mouth. If you ever were to consider this, you would need to do extensive research and find a surgeon with great experience in this procedure and managing its risks.However, I would first trial Botox as this might be a very simple and safe answer for you.Best of luck!Dr. SubbioBoard-Certified Plastic SurgeonNewtown Square/Philadelphia, PA
