Ten horses presented with severe distortion of the facial contour, crepitus on palpation and mild to moderate epistaxis. Individual horses also showed ocular damage, ptosis, severe dyspnoea and movement of the facial bones concurrent with respiration. The fracture fragments were exposed using a large curvilinear incision and elevated using a retractor, periosteal elevator, chisel or Steinmann pin. The fracture fragments were unstable following reduction and fixation was necessary. Stabilisation was achieved with polydioxanone sutures placed through holes drilled in opposing sides of the fracture lines. Polydioxanone sutures provided good stability and had better handling properties than wire. There was good apposition of fracture edges and minimal complications. Use of polydioxanone sutures can also avoid the expense and complexity of plate fixation in selected cases, and should be considered as an alternative to fixation with stainless steel wire in any facial fracture that adjoins stable bone.
十匹马出现面部轮廓严重变形、触诊时有捻发音以及轻度至中度鼻出血。个别马匹还表现出眼部损伤、上睑下垂、严重呼吸困难以及面部骨骼随呼吸运动。通过一个大的曲线切口暴露骨折碎片,并用牵开器、骨膜剥离子、凿子或斯氏针将其抬起。骨折碎片复位后不稳定,因此需要固定。通过在骨折线相对两侧钻孔并穿过聚二氧六环酮缝线来实现稳定。聚二氧六环酮缝线提供了良好的稳定性,并且比钢丝具有更好的操作性能。骨折边缘对合良好,并发症极少。在某些情况下,使用聚二氧六环酮缝线还可以避免钢板固定的费用和复杂性,对于任何与稳定骨相邻的面部骨折,都应考虑将其作为不锈钢丝固定的替代方法。
