The purpose of this prospective study was to compare and evaluate functional and esthetic treatment outcome of single point fixation at frontozygomatic (FZ) suture with single point fixation at zygomaticbuttress (ZB) in patients with minimal to moderately displaced zygomatic-complex (ZC) fractures. Materials and methods: A randomized control trial was conducted on 20 patients, (10 patients in each group) reporting to FDS MSRUAS and Ramaiah Hospitals with minimal to moderately displaced ZC fractures. Group I, treated by open reduction and single plate fixation at the FZ region, and group II treated by open reduction and single plate fixation at ZB region. Parameters such as anatomic form, function, esthetics and complications were evaluated and compared pre-operatively, immediate post-op and third month post operatively.
Demographic data collected from the patients included age, sex, occupation, etiology of injury and time period elapsed from the time of injury to initialization of definitive treatment. There was no statistically significant difference in stability, function and esthetics achieved with fixation at FZ or ZB region. Although fixing at the buttress region through intraoral incision offered a few benefits over FZ region, like no scarring or palpability of plates/screws, ease of reduction and use of varied reduction instruments along with visualization of infraorbital rim and the nerve through same incision.
It can be concluded that minimal to moderately displaced ZC fractures can effectively be treated and adequate stabilization achieved by single point fixation either at FZ or ZB region depending on individual merit of each case.
