Abstract

Zygomatic complex fractures, many at times present challenging diagnostic and reconstructive problems for the surgeon. Treatment options for reduction of isolated zygomatic bone fractures range from closed reduction without fixation to open reduction with multiple points of exposure and fixation such as 1-point, 2-point, 3-point fixation depending upon degree of displacement. There is a general consensus that open reduction is the treatment of choice for comminuted fractures but the reduction method for management of less severe fractures is still controversial. In the present study, 110 patients of ZMC fracture were randomly assigned into two point (group 1) or three point fixation (group 2). Road traffic accident was the cause of zygomatic fractures in 80% cases, accidental falls in 10%, sports injuries and assault 10%. Patients were reviewed clinically, photographically as well as radiographically 1 week postoperatively followed by review after 4 weeks and 12 weeks. Reviewing results from all the aspects and keeping in mind the limitation and variables in this study, it can be concluded that fixation of ZMC fracture with two point fixation is an equally effective method as three point fixation; that provides stability in all three planes and results in no displacement in moderately displaced zygomatic bone fractures. However the cases with muscle entrapment or infra orbital rim displacement more than 2 mm or muscle entrapment; an additional site should be addressed to reduce the post-operative complications like dystopia or enopthalamos.
