Abstract
Extensive trauma to the forehead, resulting in large penetrating wounds of the frontal sinus that extend into the frontal lobes of the brain, has traditionally been treated by frontal sinus ablation. Although this operation eliminates dead space, it leaves the patient with a depressed area in the forehead with little protection for the brain. The success of Nadell and Kline in replacing skull fragments following compound depressed skull fractures yet avoiding infection has spurred us to attempt this technique in penetrating injuries of the frontal sinus. By preserving the anterior frontal sinus wall, we have not only afforded protection for the frontal lobes of the brain, but, at the same time, avoided the cosmetic defect that would be left by an ablation procedure. This procedure has been performed on two patients at our institution. After a two-year follow-up, excellent forehead profile preservation has been achieved and there has been no evidence of bone absorption or infection at any time since surgery.
