That doctor certainly didn't tell you that orthodontics is needed before and after orthognathic surgery, and the operation process may be far more than 1 hour. If it is maxillary surgery, it is even more dangerous. After surgery, the upper and lower teeth should be fixed for one month, and you can't eat with your mouth open.

The whole treatment process takes two years. The effect is good, but it won't be quick.

I also recommend Peking University Stomatological Hospital, which is expensive and worth the money.
