Abstract
Ectopic eruption of teeth in the maxillary sinus is an uncommon phenomenon, with third molars the most frequently involved. Teeth affixed to the posterior sinus wall represent a particularly rare anatomical variant with unique surgical challenges. A 21-year-old male presented with an ectopic maxillary third molar (#1) affixed to the posterior wall of the right maxillary sinus. The tooth was successfully removed with endoscope assistance, and the anterior wall of the maxillary sinus was replaced and secured with a 0.8 mm fixation plate. The patient recovered without incident. This report adds another treatment option to the management of a rare occurrence of an ectopically erupted wisdom tooth within the maxillary sinus. It can also be utilized for any foreign body in the antrum (FBITA).
