[Frontal sinus impression fracture as a collision sequelae in football].

4 soccer accidents, causing the rare case of impression fracture of the frontal sinus, are introduced as soccer-specific lesions, which are caused by head-to-head collisions, being due to heading-maneuvers. Mostly the right frontal sinus was hurt. The indication for an operation is the obvious dislocation of the osseous fragments. Primary intentions for an intervention are the precise reconstruction of the anterior wall of the frontal sinus because of esthetic reasons and a permanent drainage in order to avoid late complications as for instance mucopyoceles, if the infundibulum has been damaged. The therapy of choice is the osteoplastic frontal sinus operation, using a bicoronary incision.
