Abstract: A 66-year-old woman presented with a 6-month history of unilateral right nasal obstruction and rhinorrhoea not responding to medical therapy. She had a history of dental implantation for an unerupted tooth on the right side 3 years ago. Physical examination including flexible nasendoscopy demonstrated yellow debris in the right middle meatus. CT paranasal sinuses demonstrated a radiopaque lesion in the right anterior ethmoid sinus and resembled the unerupted tooth. The tooth was removed endoscopically from the right nasal cavity without complications. This case highlights the importance of eliciting an accurate dental history and considering ectopic dentition as a differential diagnosis in a patient with unilateral symptoms of sinusitis.
