I had punctured sinus from left molar extraction. Can an MRI show if my sinus has healed properly?

Question:  

Had punctured sinus (during left molar extraction).  Socket was not closed properly.  Had to have repair work done 4 days later to close socket.
Had bouts of nasal congestion, burning sensation in nasal cavity, light headedness.Tilting my head back seems to help sometimes.

I am not sure my sinus healed properly.  Have had pulling sensation in left nostril.  Noises in left ear have been diagnosed as eustachian tube dysfunction.

First problem with ear was suctioning sound when I yawned (socket had sealed).  Then clicks when  congested.  Now clicks randomly.  Popping sound when I burp sometimes and the most recent is pressure in ear as if underground on train.

Can an MRI show if my sinus has healed properly?  Any image that is not radioactive?

Answer:

First of all, thank you for your question.  The roots of several teeth- especially our molars, can be quite close or actually within the maxillary (cheek) sinus.  Infections in the tooth roots or dental extractions can spread infection into the sinus- and are typically difficult to treat as the oral bacteria are often quite virulent.

Treating odontogenic (dental caused) sinus infections involves appropriate antibiotics- usually best based on an actual culture- and treating the dental problem.

Today, we will often use balloon sinuplasty- opening up the sinus with a balloon in the office- to drain the sinuses if needed.

The best way to see if a sinus infection has resolved is with CT scanning.   Low dose scans can be done, and while the radiation is less than with typical scans, there still is some radiation.  MRI’s use electromagnetic waves rather than radiation, but do not show bone- and tend to over read sinus problems.  They are much less useful, but a normal sinus MRI would probably be enough to avoid using CT scanning.

I hope this clears things up.
