Frontal sinus fractures.

Frontal sinus fractures are rare in children, uncommon in adolescents, and most commonly the result of high-impact collisions of the face with an immovable object. Most are associated with other facial and head injuries; intracranial injury should be considered an invariable concomitant of any frontal sinus fracture that involves the posterior sinus wall. Proper management of frontal sinus fractures requires a multidisciplinary team approach.
