아방영아의 대선문발육에 대하여

Abstract

The size of anterior fontanelle and its closing were observed in 1208 infants who were seen in the Well Baby Clinic and the nursery of Seoul National University Hospital. They were born during the period of 1958 to 1960. No obviously malnourished and chroniclly ill infants were included in this study. Thirty newborn infants were delivered at term uneventfully and three to five days old at the time of study. The size of anterior fontanelle was measured according to Elsasser's method and its complete obliteration was determined by palpation. In the newborn infants, the anterior fontanelle was measured 2.5±0. 9cm., ranging from 1.3 cm to 9R 5.1 ern. It increased in size until the age of one month, but then became gradually smaller in size during the rest of the infancy. Its complete obliteration occured with extremes at the age of four months. The percentage of infants whose fontanelle were closed was 55 per cent by 15months and 85 per cent by 24 months of age.
