I had orthognathic upper and lower surgery with this doctor, and he ruined me. I had a mild underbite and no other problems. However, he left me with a severe cant (my upper jaw slants down on one side) and my chin is obviously curved to the left AND I am completely numb on my bottom right lip and chin, which makes my mouth move awkwardly when I speak or smile. The part that is numb doesnt move so my mouth is asymmetric. Also, if i were to lift up my chin, my chin slants far down to the right. I REALLLY REGRET having surgery with this doctor. He used to work at Kaiser, but he said he was doing too many surgeries, which he was getting tired of, and he can make so much more money opening his own practice, so he did at Premiere Oral and Maxillofacial Surgery of Orange County 4980 Barranca Pkwy, and he works withe Dr. Blair Ota. I dont have any experience with Dr. Blair Ota, but DO NOT GO TO Dr. Eric Kim
He is really good at talking about how he knows the latest technology, etc... but beware he is using his patients as experiments for the computer assisted jaw surgery. He even personally told me that he was unhappy with how his patients were turning out and the computer was giving the wrong measurements, but I trusted him because he told me he would use both his judgement and the computer assisted technology and because my orthodontist referred him. Well come to find out, the ortho didnt have any experience with this guy, and I was referred to him because Dr. Relle who is a great surgeon left Kaiser. As for Dr. Eric Kim, II became one of his experimental patients with the computer laser program, and he left me more of a mess than before the surgery. I am trying to fight to get the surgery done again but not with him of course.
PLEASE do your research!
