RESUMEN
<p><b>OBJECTIVE</b>To investigate the effect of soft tissue incision and rigid internal fixation in the treatment of zygomatic fracture.</p><p><b>METHODS</b>70 cases with zygomatic fracture were entered into the study. The clinical data of 65 patients who were performed operations in the treatment were analyzed. The study focused on the incision, number and locations of Titanium plate. The facial contour, reduction,fixation, healing of incision, facial bisymmetry and complications of the operation were followed up 3 - 24 months after surgery.</p><p><b>RESULTS</b>All the incisions were primary healing. Clinical and radiologic assessment of reduction was symmetric and stable in 91.5% of all cases, asymmetric in 8.5% of all cases. Subcutaneous hematoma happened in 5 cases, Ti plate exposure 1 in case, scalp scar width was more than 0.5 cm in 6 cases, frontal part or scalp paresthesia 8 cases.</p><p><b>CONCLUSIONS</b>Coronal scalp incision has advantages such as good exposure, precise removal of the bone block and good symmetry of both sides. RIF can improve the stability of fracture, promotes fracture healing and guarantees the rehabilitation of zygomatic complex. direct reduction and rigid internal fixation with Titanium microplate or miniplate are satisfactory in zygomatic fracture.</p>
