We describe the case of a 76-year-old man who presented with symptoms of chronic nasal obstruction and recurrent sinusitis of many years' duration. The patient's history and radiographic findings established a diagnosis of a complex odontoma of the nasal cavity. The mass was surgically excised, and the diagnosis was confirmed by histopathology. The occurrence of an odontoma in the nasal cavity is extremely rare.
