Pain in Palate After Rhinoplasty

Although upper lip and front tooth pain or numbness can occure after septoplasty or rhinoplasty, what you are describing seems like an unrelated issue. I agree with Dr. Joseph that this is probably an intubation related problem.
Salt water rinsing is a good idea. If it is really painful, then sometimes a steroid ointment or an oral anesthetic paste can be prescribed. You should contact your surgeon if the issue persists.
Good luck.

I often say that your nose won't hurt after Rhinoplasty Surgery, but your throat might. What you're describing is likely what you suspect: trauma from the orotracheal tube that was placed to secure your airway during surgery.
This will likely heal without incident, but you should have it checked by your covering physician. You can get topical treatment for the discomfort, and you'll have the peace-of-mind that comes with a reassuring diagnosis. If there is no covering surgeon, you should consult a board-certified ENT for evaluation and management.
I hope this is helpful for you.
