Summary
Normal vaginal birth is associated with considerable distortion of the fetal head (1–3). As the head passes through the pelvis, it is subjected to pressures roughly double those in the amniotic cavity (4, 5). Magnetic resonance imaging of term fetuses during labor shows that the frontal and parietal bones shift considerably and the brain itself changes shape, usually becoming taller in the vertex-to-skull base plane (6, 7). Overlap of calvarial bones occurs at the sagittal suture and to a lesser extent the lambdoid suture (8). The occipitofrontal circumference rebounds quickly within 2–3 days and is fully restored 1–2 weeks after delivery (9, 10).
