Abstract
We treated twenty-three patients with blunt or penetrating wounds of the frontal sinus from 1978 through 1983. Nondisplaced anterior wall fractures were observed or explored. Posterior table fractures—with displacement confirmed by computed tomography or polycycloidal tomography—were explored. Either obliteration of the sinus or nasofrontal duct reconstruction with a Sewall-Boyden-McKnaught flap was selected, depending on the magnitude of duct injury. In all cases, the anterior wall was primarily reconstructed. All penetrating wounds with posterior table involvement were treated by cranialization of the frontal sinus and temporalis muscle obliteration of the nasofrontal ducts. Only one case of meningitis occurred, resulting in prolonged hospitalization.
