Evaluation of frontal sinus fractures.

Forty-six instances of frontal sinus fracture were reviewed to determine the factors that are important in the initial clinical and radiologic evaluation. Associated injuries, the appearance of the forehead, and roentgenographic studies were all considered. Polytomography is the most accurate diagnostic technique and is justified in all patients. The otolaryngologist must examine all roentgenograms personally, with particular attention paid to the nasofrontal duct region and to the magnitude of depression of fracture fragments.
