Two Cases of Osteoma of the Frontal Sinus and the Statistical Observation in Japan

　I．はじめに

　前頭洞骨腫は欧米では数多くみられるが，本邦では比較的まれな疾患とされている。筆者らは，最近2例の前頭洞骨腫症例を経験したので，本邦における報告例の統計的観察を加えて報告する。

　A 52-year-old female complained of swelling and tenderness of the right upper eye lid. Osteoma was removed and weighed 5.0g. A 30-year-old female had no complaint but osteoma was removed and weighed 1.0g. Both patients were operated by Killian's method. The statistical observation about the similar cases reported in Japan was made.
