Treatment of frontal bone fracture sequelae through inversion of the bone fragment.

Treatment of frontal sinus fractures depends on the structures involved: the anterior wall, the posterior wall and the nasofrontal duct. It may vary from the correction of the defect in the anterior wall to the cranialization with obliteration of the nasofrontal duct. The inversion of the frontal sinus's anterior wall to correct the defect in the fractured region is a good treatment option for sequelae, since this technique eliminates or reduces the use of biomaterial in the area, and allows direct assessment of the permeability of the nasofrontal duct. This work describes the technique of fractured segment inversion for the treatment of frontal sinus fracture sequelae in a motorcycle accident victim.
