Prenatal gender-customized head circumference nomograms result in reclassification of microcephaly and macrocephaly.

ABSTRACT:

Background

Local and worldwide prenatal charts for estimated fetal weight and postnatal charts for head circumference are gender specific. However, prenatal head circumference nomograms are not gender customized.

Objective

This study aimed to create gender-customized curves to assess between-gender head circumference differences and to study the clinical significance of using such gender-customized curves.

Study design

A single-center retrospective study was conducted between June 2012 and December 2020. Prenatal head circumference measurements were obtained from routine estimated fetal weight ultrasound scans. Postnatal head circumference measurement at birth and gender were retrieved from computerized neonatal files. Head circumference curves were created, and the n
