The objective of this study was to improve the accuracy of sonographic fetal weight estimation in macrosomic (> 4000 g) fetuses by combining the cheek-to-cheek diameter (CCD), an indicator of subcutaneous tissue mass, with the biparietal diameter (BPD) and abdominal circumference (AC) in generating a new weight formula.
