How Long Does A Cephalohematoma Take to Resolve?

Discussion Cephalomatomas occur relatively commonly in 0.2-3% of newborn infants. They are blood collections in the subperiosteal skull bones, usually in the parietal area. They are usually unilateral but can be bilateral. They do not transilluminate. They are felt to be caused by pressure or other trauma and occur in vaginal and cesarean deliveries, with presumed periosteal disruption leading to externally located bleeding (not on the brain side of the bone). The blood fills the space with some pressure building up and the blood acts to tamponade itself. The blood coagulates, slowly organizes and is reabsorbed. If reabsorption is delayed then ossification can occur but these also usually reabsorb but more slowly. Increased risks include prolonged overall or second stage of labor, macrosomia, abnormal fetal position, multiple gestation, weak uterine contractions and instrumented delivery such as vacuum extractor or forceps. Larger cephalohematomas are more likely to have ossification. The differential diagnosis includes caput succedaneum, vacuum caput, subgaleal hematoma, congenital abnormalities such as leptomingeal cyst or meningocoeles. Persistent bleeding could also be an indication of a hemophilia. Underlying skull fracture can occur but is unlikely. If there is more significant bleeding, then hyperbilirubinemia may be accentuated. Treatment is usually reassurance for families and watchful waiting. Compressive dressings can be applied around birth. Aspiration or other su...
