抄録

In this report, we report of a patient with a dental foreign body in the maxillary sinus, which was considered to be a decayed tooth. The patient was a 23-year-old woman with nasal purulent discharge, fever, and pain in the right cheek. She had no previous history of nasal or sinus problems. However, past history included treatment for decay in the 7th upper right tooth. Her symptoms persisted despite temporal improvement with conservative treatments. The plain sinus x-ray film and the CT scan revealed findings consistent with chronic maxillary sinusitis. In addition, these examinations demonstrated a tooth-shaped calcification, suggesting the presence of a foreign body from a decayed tooth in the center of the right maxillary sinus. Endoscopic sinus surgery (ESS) was performed under general anesthesia. After removing the uncinate process, the natural ostium was identified. An enlargement of the natural ostium and the creation of a nasoantral window were performed. The foreign body was easily identified and removed. There were neither edematous changes nor fluid retention in the right maxillary sinus. In the follow-up period, the patient had no symptoms. ESS could be a useful technique to remove foreign bodies in the maxillary sinus.
