Foreign body in the right maxillary sinus cavity: clinical case

Abstract Foreign bodies in the paranasal sinuses are rare clinical occurrences. In the maxillary sinus, these foreign bodies may include tooth roots, dental impression materials, root-filling materials, and dental implants. This article presents an unusual case of a large foreign body of endodontic origin that was successfully removed from the maxillary sinus. We share our experience with a case involving a foreign body in the left maxillary sinus (a tooth). The removal of paranasal foreign bodies is always a challenging procedure. However, with the advancement of diagnostic techniques and the transnasal approach using functional endoscopic sinus surgery, such procedures can now be performed safely.
