Ectopic located tooth which obstrcuted the maxillary sinus ostium

Abstract

A giant mucocele secondary to obstruction of the maxillary sinus ostium with an ectopic tooth. Mucocele secondary to ectopic maxillary tooth is very rare. We present a case of giant mucocele which is caused by obstruction of the maxillary sinus ostium with an ectopic tooth. The patient presented with headache and facial asymmetry. CT of the paranasal sinuses revealed an ectopic maxillary tooth, obstructing the maxillary sinus ostium and a mucocele of the maxillary sinus that erodes bony walls. The ectopic tooth was removed with Caldwel-Luc approach and the mucocele was marsupialized to the middle meatus with endoscopic sinus surgery. Ectopic maxillary tooth should be kept in mind as rare cause of paranasal sinus mucoceles.
