Rationale for Surgery in Growing Fractures of the Skull. J Neurosurg. 1970; 32:427–430)) ((Arseni CS. Growing Skull Fractures of Children. A Particular Form of Post-Traumatic Encephalopathy. Acta Neurochir. 1966; 15:159–172)). Usually requires both a widely separated fracture AND a [[dural tear]]. Mean age at injury: < 1 year; over 90% occur before age 3 years ((Lende R, Erickson T. Growing Skull Fractures of Childhood. J Neurosurg. 1961; 18:479–489)) (formation may require the presence of a rapidly growing brain ((Gadoth N, Grunebaum M, Young LW. Leptomeningeal Cyst After Skull Fracture. Am J Dis Child. 1983; 137:1019–1020))), although rare adult cases have been described ((Britz GW, Kim DK, Mayberg MR.
