This history started 20 years prior to admission which was associated with profuse, purulent, brownish discharged and facial pain on the affected side. The patient had been previously diagnosed by a number of physicians as a case of allergic rhinitis, moderate persistent and was treated with unrecalled intranasal corticosteroids which only provided temporary relief of the symptoms. A paranasal sinus computed tomography scan was requested which revealed pansinusitis more on right maxillary sinus; obstructed right ostiomeatal unit; right intranasal tooth and etopic tooth within the alveolar process of the maxilla and mild right mastoiditis. Endoscopic sinus sugery with tooth extraction under general anesthesia was performed to remove the intranasal tooth. On follow-up week later, resolution of the symptoms was noted. Physical examination revealed no nasal mucosal abnormalities. Histologic examination later confirmed its dental nature. ER -
