Evaluation of a Single Miniplate Use in Treatment of Zygomatic Bone Fracture

Abstract

Different methods of internal fixation of simple displaced zygomatic fracture, such as wiring, miniplate, and screw fixation, were compared for postreduction rotational stability caused by muscular forces. This study was performed to evaluate the minimally invasive therapy in cases of zygomatic bone fracture. Seventeen patients were treated by percutaneous hook reduction and miniplate fixation along the frontozygomatic suture. Postoperatively, repositioning of aesthetic and stability and also bone ends approximation were assessed clinically and radiologically. The patients were followed up for 6 to 49 months. Preoperative symptoms were subsided except the infraorbital sensitivity disturbances in one of the patients. Postoperative complications such as diplopia and hematoma were minimal and subsided by time. In this study, orbitozygomatic, commuted, and zygomatic bone fractures simultaneously with diplopia were excluded. We showed that treatment of an isolated zygomatic bone fracture according to aesthetic and functional requirements may be achieved by insertion of a single miniplate at the lateral rim of the orbit.
