A case of a maxillary cyst with a foreign body in the maxillary sinus

Abstract

We report a case of a maxillary cyst with a foreign body in the maxillary sinus. A 77-year-old woman presented with a left nasal obstruction and mucopurulent discharge. CT showed a left maxillary cyst containing a foreign body, and endoscopic sinus surgery to remove the foreign body was necessary. The removed foreign body turned out to be a fragment of a tooth. After surgery, the patient's symptoms disappeared.
