A foreign body in the maxillary sinus

Abstract

We report a foreign body in the maxillary sinus. A 46-year-old man was referred to our hospital because of misplacement of his implant fixture. X-ray and CT examinations revealed a misplaced implant fixture in the left maxillary sinus, and thickening of mucosa of the sinus. Under local anesthesia, Caldwell-luc procedure was performed and the implant fixture was removed from the sinus without any complications. We should be aware that foreign bodies can be inserted into the maxillary sinus by dental treatment.
