Small holes on the roof of my mouth?

It is impossible to diagnose you from a far, and without photos, but it is possible that you are noticing the Greater and/or Lesser palatine foramina.  These are normal "holes" on either side of the palate at the junction between the hard and soft palate that transmit the Greater and Lesser Palatine nerves.  It is possible that after sinus surgery, you are just more observant, and you have noticed these normal structures.  The best person to evaluate you in person is your ENT doctor.

Hello and thank you for your question. What you are describing sounds perfectly normal and was likely there before your surgery. You probably didn’t notice them before since you weren’t as focused on the roof of your mouth. I would say that if your doctor did not see a problem, you don’t need to worry. However, if you develop symptoms or the holes appear to get larger, I would certainly schedule another evaluation to determine the underlying cause. Good luck!

 The small hole in the roof of the mouth can occur from a variety of situations such as  tract between the sinuses the upper teeth. It's very important to make sure these holes in the mouth do not communicate with your sinus cavities. A thorough internal examination of the mouth and nose is required ,while a CAT scan of the sinuses is required to determine what is the cause of the problem.

Thanks for your question. The holes are normal anatomic structures, they are the passage ways for the nerves that control sensation to the area. Please do not be alarmed by their presence. Hope this helps. 

Since your ENT looked at the roof of your mouth and said he did not see a passageway to your nose, and they are not symptomatic, they were probably there before surgery and not noticed. Nasal surgery of the septum can sometimes cause a burned or numb sensation of your front four upper teeth or the area just in back of them which will resolve a few weeks after surgery. There are depressions for nerves and vessels in this area and the bone can also be elevated making the holes look larger. If you ignore them they will probably not bother your. Have your surgeon look at them again the next time you see him or her.
