Can somebody tell me how much does facial asymmetry surgery cost?

Consultations: You would have to be seen by a plastic surgeon in order to discuss treatment and fees. Get a few consults and you will have the information you need in order to make an intelligent decision. "facial asymmetry" is a very broad category. The extent of the surgery, the experience of the surgeon and location of the office will be some of the factors in determining fees.

Evaluation needed: What you are asking may involve several specialties like oral-maxillofacial surgeon and plastic surgeon. I would begin with oral surgery consultation.

Yes: An Oral and Maxillofacial Surgeon can tell you. Depends on severity, cause, fee schedules in your area, insurance coverage, impatient or outpatient, and myriad other factors. See an Oral Surgeon.
