Study of relationship between changes in size of posterior fontanelle with gestational age.

In this study we have measured size and area of posterior fontanelle and have studied its relations with gestational age in human fetuses. This study is aimed to provide a range of normal posterior fontanelle dimensions and to provide base for further research in Asian population on morphology of posterior fontanelle and see if there exists any significant difference when compared to European & African studies. For this fifty fetuses were arranged in 5 groups according to their gestational age. Mean posterior fontanelle size and area of each group is measured. After statistical calculations it was observed that posterior fontanelle size and area both vary significantly with gestational age.
