以颧蝶缝为标准复位颧骨骨折

Sphenozygomatic Suture as a Guide in the Reduction of Zygomatic Fracture

目的 比较以颧蝶缝为标准和采用常规方法复位颧骨骨折的效果。方法 选择Zingg分类的B型和C型骨折 5 5例 ,分别采用以颧蝶缝复位和常规方法复位 ,术后比较面型恢复程度和X线片上颧骨颧弓的对称性。结果 36例以颧蝶缝为标准复位的患者术后均获得满意的面型 ,19例常规方法复位的患者有 5例术后面型及X线片颧骨颧弓不对称。结论 颧骨骨折手术复位时 ,以颧蝶缝为标准 ,结合颧骨各突起骨折的对位对线可使颧骨准确复位 ,从而恢复正常的面型。

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 other fracture line was 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 symmetry were 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.
