We experienced a case of a 10 year old girl having painless, hard osteoma originated from bilateral nasal bones, who admitted on April 21, 1970. The mass was bony hard and fixed to the underlying nasal bones, and covering skin of external nose was healthy. The anterior rhinoscopic examination revealed normal findings. The radiological finding showed dense bony shadow with smooth margin arising from the nasal bones. The surgical removal was performed under general anesthesia and the mass was easily removed completely. The histological dragnosis was osteoma.
