Objective: Supernumerary teeth, presenting in excess of normal teeth, are commonly found in the upper incisor area. However, supernumerary teeth appearing in the nasal cavity is rare and has primarily been documented through case reports. Here we present a case report of an adult patient with nasal obstruction, decreased sense of smell, and intermittent epistaxis, who was found to have an intranasal supernumerary tooth by computed tomography imaging and pathological confirmation.
Methods: Case Report Results: Computed tomography imaging and endoscopic evaluation revealed a hyperdense mass in the nasal cavity. Pathology confirmed the presence of a calcified mass consistent with a supernumerary tooth in his nasal cavity. Following endoscopic extraction, the patient’s symptoms resolved.
Conclusion: Supernumerary teeth should be considered on the differential diagnosis for nasal obstruction and be evaluated with radiology, endoscopy, and pathology to exclude serious or malignant conditions such as chondrosarcomas and osteosarcomas. Endoscopic removal of supernumerary teeth is safe and effective.
