Cephalohematoma is a common birth injury that occurs in 1%-2% of vaginal deliveries and 3%-4% of vacuum or forceps assisted deliveries. During labor, blood vessels in the scalp of the infant are ruptured and blood pools in between the skull and the scalp. Since the blood is trapped between the scalp and the skull, the brain remains free of pressure. Cephalohematoma, commonly known as a newborn hematoma, is the rupture of blood vessels in the infant scalp as a result of the baby’s head passing through the birth canal.
