The author has carried out the statistical standards on liner and angular measurements of sells turcica in 244 normal Korean of various age group by means of lateral cephalometric radiography. The results were as follows; 1. The linear measurements between Ant-Post distance and distance from the tip of tuberculum of sellae to posterior clinoid process were obtained 14.81mm, 9.85mm in the age of 5 years old male and 14.44mm, 9.52mm in female, respectively. There was no outstanding difference with age, but more predominant in female than male. 2. The linear measurements of inferior depth show somewhat increases but no changes in superior depth. 3. It has been showed that the greatest width revealed significant increment beyond 15 years old of both sexes in Korean. 4. None of the significant difference in angular measurement was found with age, but angulation for dorsum sellae decreased after 15 years of male. 5. Generally speaking, increment rates of female in each items were greater than male.
