A comparative study between two point and three point fixation for zygomatic complex fractures

Abstract

The fractured fragments of a zygomatic complex fracture near the suture lines needs to be restabilized by open reduction by fixation. Depending on the displacement of fracture segments and anticipating the stability of the reduced fracture, one, two or three point fixation is applied. The choice of points of fixation is inclusive and best left to surgeon and depending on the fracture type.The aim of this study was to compare and evaluate functional and aesthetic outcome of two point fixation at frontozygomatic suture and buttress with three point fixation at FZ, buttress and infraorbital region in patients with zygomatic complex fractures.This study included 30 patients who underwent treatment of zygomatic complex fractures between 2011 to 2013. Fifteen patients were treated with ORIF using two point fixation and remaining 15 with three point fixation and patients were evaluated and compared preoperatively, first post op day, 7 day, first month and third month post op for anatomic form, function, aesthetics and complications. There was no statistically significant difference in stability, function and aesthetics achieved with fixation and aesthetics. Two point fixation modality for displaced zygomatic complex fractures is as effective as three point fixation. The surgical treatment varies from surgeon to surgeon and also depends on the type of fracture.
