FETAL HEAD MEASUREMENTS CEPHALIC INDEX AND FETAL HEAD SHAPE
There can be much variability in the shape of the fetal head, and for that reason the shape of the cranium should be evaluated closely with each examination.
— The cephalic index is a useful tool for indicating the shape of the fetal head.
— A brachycephalic (brachycephaly) head shape is one that is considered round or short and wide, while dolichocephaly, also referred to as scaphocephaly, denotes an elongated, narrow head shape.
— Other abnormal skull shapes include strawberry, lemon, and cloverleaf.
