I recently had a very hard TMJ surgery performed by Dr. Heffez. Not only Dr. Heffez was the only specialist who correctly diagnosed my case (I have seen at least 7 other people), he was also extremely skillful and attentive. My surgery was done at a state hospital, so don't expect any luxurious accomodations. However, for a hospital procedure, it really doesn't matter what surrounds you as long as you come out alive and well and your surgery is successful. I recommend Dr. Hefez to anyone who needs a surgical expert in the field where many fail to rise to his standards.
P.S. I am still healing, so my treatment success cannot be fully accounted for at this time.
