Motivation: The Orthognathic Surgery is a surgical technique widely used in the planification of multidisciplinary treatment for the correction of Dentofacial Deformities. All types of osteotomy described in maxilla and mandible needs a fixation method (wire or rigid) to ensure bone healing.
Problem statement: Which is the bone fixation method that has the mayor rate of surgical site infection in Orthognathic Surgery?
Methods/Approach: The aim of this study was to compare the rate of surgical site infection of both bone fixation methods (wire and rigid) in ASA I patient treated with Orthognathic Surgery. This retrospective cohort study had an universe of 649 patients, then only 400 patients were selected after applied the inclusion and exclusion criteria. Therefore of this final sample two groups were made: Group A those who had rigid fixation ( n = 121) and Group B with wire fixation ( n = 279).
Results: 26 of the 400 patients had surgical site infection, 10 of the 26 infected were in the rigid fixation group and 16 were in the wire fixation group. After a t -student test was made, no statistical signification was observed in both groups ( p = 0.1199).
Conclusion: The rate of surgical site infection in the wire fixation group (during the 13 years that were investigated) is minor than the rate infection of rigid fixation group, without a statistical signification between both.
Conflict of interest: None declared.
