Profound Deafness Due to Head Trauma

Profound and permanent deafness following a severe injury to the head has occasionally occurred in childhood as well as in adult years. The injury to the inner ears may be caused by a fracture of the base of the skull, the fracture passing through one or both labyrinths or by a concussion injury to one or both inner ears. Head injuries in children sufficient to produce bilateral profound inner ear damage have usually been caused by the impact of the head striking a hard surface such as may happen in a fall or by being knocked or thrown to the pavement by a moving vehicle or by injury in a motor accident.
