title: Endoscopic removal of a dentigerous cyst producing unilateral maxillary sinus opacification on computed tomography.
abstract: We report the case of a 14-year-old girl who was referred to us with a 2-year history of abnormal panoramic dental x-rays. Computed tomography of the paranasal sinuses demonstrated a left unilateral maxillary sinus opacification that had been produced by an ectopic molar. The tooth was removed via an endoscopic approach rather than with a traditional Caldwell-Luc procedure. A nasal endoscope was used to create a middle meatal antrostomy and deliver the tooth and its cystic contents. The patient recovered without complications, and she exhibited no signs of recurrence at the 2-year follow-up.
