Objective To retrospectively investigate the effectiveness of sphenzygomatic suture as a guide in the reduction of zygomatic complex fracture.Methods 55 cases of zygomatic complex fracture classified according to Zingg classification were treated, sphenozygomatic suture in group 1 (n=36) was reduced first, then the otherfracture linewas reduced, in group 2 (n= 19), malar bone was reduced according to superficial fracture line. Patients were followed up for 4 weeks to 3 months, aesthetic result and X-ray symmetrywere observed.Results All patients in group 1 were restored with satisfactory facial contour, 35 cases got precise reduction, 5 cases in group 2 were asymmetry.Conclusion During open reduction of complex zygomatic fracture, sphenozygomatic suture should be reduced at first as a guide, so as to get precise zygomatic complex reconstruction and normal aesthetic outcome.
