The role of endoscopic sinus surgery in maxillary sinus foreign body removal

Abstract

Extraction of impacted third molars is a common surgical procedure performed by oral surgeons and dentist. Dislodgement of the molar tooth into the maxillary sinus cavity can occur during the procedure. It comprises 0.6-3.8% of iatrogenic foreign body entrapment in the paranasal sinus. We report an unusual case of impacted maxillary third molar tooth that was accidentally displaced into the maxillary sinus during extraction and remained almost 1 year without any symptoms and removed via endoscopic sinus surgery.
