Rhinoplasty before orthagnathic/jaw surgery?

Rhinoplasty can be done either before, during or after jaw surgery.  I usually recommend the jaw surgery first.  Then it will be easier to plan for what needs to be done as far as the nose is concerned.  Each case needs to be individually evaluated depending on your desires and the advice of your surgeon.

You are thinking correctly. The first move should be to consult with both the oral surgeon and the nasal cosmetic surgeon. One issue which must be addressed is your nasal passages. Is there any blockage? That is important since to put you to sleep for the jaw surgery, the anesthesia specialist has to put a tube through your nose into the lungs. If the nose if blocked, perhaps from a deviated septum, that may have to be addressed first. Both doctors should speak with each other after you have consulted since they will recommend the best order of the two surgeries.

 If the upper maxilla in the lower mandible or undergoing orthognathic surgery, that should probably be done first, and then a rhinoplasty done afterwards.
