a localized effusion of blood beneath the periosteum of the skull of a newborn, due to disruption of the vessels during birth. Cephalhematoma, in contrast to caput succedaneum, does not cross cranial suture lines. It is firmer to the touch than an edematous area: it feels like a water-filled balloon. Cephalhematoma usually appears on the second or third day after birth and disappears within weeks or months.

Vacuum-assisted deliveries have a low risk of complications such as cephalohematoma when the cup is placed in the midline of the fetus's head with the center of the cup 3 cm in front of the posterior fontanel, and when the cup is applied only when the fetus is in a low station with the fetal caput visible, said Dr.
