We report two cases of ectopic inverted tooth in the nasal cavity. Case 1 and 2 were an 8-year-old female with left epistaxis and a 10-year-old male with right epistaxis respectively. In both cases, computed tomography revealed that the attenuation of the mass was the same as that of the oral teeth. We removed the ectopic inverted tooth completely with endoscopy by an endonasal approach. We describe their clinical courses, and the etiology, diagnosis and management of the ectopic inverted tooth, with a review of the literature.
Key words : ectopic inverted tooth, computed tomography, endoscopy
