cephalhematoma
nounMedical Definition of cephalhematoma
: a usually benign swelling formed from a hemorrhage beneath the periosteum of the skull and occurring especially over one or both of the parietal bones in newborn infants as a result of trauma sustained during delivery
Examination of the newborns, both at delivery and at discharge, did not detect any increase in morbidity (e.g., fractures, cephalhematomas, or hyperbilirubinemia) in the infants of mothers whose labor was actively managed.— José A. López-Zeno et al., The New England Journal of Medicine, 13 Feb. 1992
