Abstract
Fractures of the zygomatico-orbital complex are most common injuries in oral and maxillo-facial surgery. Additionally to accidents in sporting activities and traffic accidents the fractures were mostly caused by interpersonal conflicts. Treatment patterns of zygomatic fractures have been changing within the last two decades from closed reposition via wire fixation to open reduction and rigid fixation of all midface buttresses by titanium miniplates. All patients with fractures of the zygomatico-orbital complex treated in the Department of Oral- and Maxillofacial Surgery of the University Hospital Tubingen from January 1988 to December 1997 were selected. From an overall of 636 patients 528 (83%) showed a fracture of the zygoma, 108 patients (17%) were operated on an isolated fracture of the orbital floor. All 636 patients underwent revision of the orbital floor, in 534 cases (84%) the defect required reconstruction which was performed with alloplastic material. The two-point-fixation at the infraorbital rim and the lateral orbital margin was the most common technique of internal fixation and was performed in 52% of all patients with malar bone fractures.
