METHODS: Twenty-five patients (15 male and 10 female, age range 16 y to 55 y) with Knight and North Group Ⅲ zygomatic fractures were included in this case series. Open reduction by intraoral approach was performed on these patients, and the fractures were fixed using absorbable plates placed at the zygomaticomaxillary buttress and infraorbital rim. Postoperatively, follow-up was undertaken to evaluate the fracture healing, mouth opening, facial asymmetry, diplopia, and paresthesia.
RESULTS: Postoperatively, all patients achieved uneventful healing; facial symmetry and wound healing were achieved, along with sensory recovery involving the infraorbital nerve. Complications such as sensory disturbances, infection, diplopia, malunion, and nonunion were not encountered in these patients.
CONCLUSIONS: Two-point fixation using absorbable plates by transoral approach can provide sufficient stabilization for Knight and North Group III zygomatic fractures.
方法:25例患者(男15例,女10例,年龄在16岁至55岁之间)的Knight和NorthⅢ组zy骨骨折包括在该病例系列中。对这些患者进行了口内切开复位术,骨折使用可吸收钢板固定在zygomatic腋窝支撑和眶下边缘。术后,随访以评估骨折愈合情况,张开嘴,面部不对称,复视,和感觉异常.
结果:术后,所有患者均顺利愈合;面部对称和伤口愈合均实现,以及涉及眶下神经的感觉恢复。并发症,如感觉障碍,感染,复视,malunion,这些患者未出现骨不连.
结论:经口入路使用可吸收钢板进行两点固定可以为Knight和NorthIII组zy骨骨折提供足够的稳定。
