A Foreign Body in the Maxillary Sinus;
A Case Report
Koji Miyata and Tomoya Nagata
(Nagahama Red Cross Hospital)
We report a case of a foreign body in the maxillary sinus. The patient was a 25-year-old female who had been admitted in our hospital with hyperphagia and vomiting. A dentist incidentally found an abnormal shadow in the right maxillary sinus on X-ray examination, but the patient did not complain of any nasal symptoms. The foreign body in the maxillary sinus demonstrated a curvedshape, but we could not accurately identify the foreign body.
Caldwell-Luc procedure was performed and the foreign body was removed from the maxillary sinus without any complications. The foreign body was identified as gutta-percha which had been used as a root canal filling material. We thought that a foreign body was accidentally inserted into the maxillary sinus during dental treatment.
Key words : foreign body, maxillary sinus, gutta-percha, dental treatment
