A member asked:

Can a polyp or retention cyst in the maxillary sinus cause imbalance?

A doctor has provided 1 answer

Possible but rare: Polyps or cysts in the maxillary sinuses are very common. Unless they are obstructing the opening to the sinus, they are completely benign and nothing should be done, especially surgery. If it blocks the opening, a simple endoscopic surgery can remove the blockage and improve symptoms.
