目的 :介绍经眶周小切口开放复位内固定治疗早期陈旧性颧骨骨折的方法与疗效。方法 :对 7例骨折3个月内的患者经眉弓外侧和睑缘下小切口行骨折复位 ,使用小型和微型钛板内固定 ,2例行眶底骨缺损重建。结果 :颧部畸形和功能障碍均获矫正 ,无明显瘢痕畸形 ,追踪观察 1～ 3年疗效理想。结论 :早期陈旧性骨折可经眶周小切口开放复位 ,眶外侧须用小型钛板固定对抗嚼肌收缩力 ,眶下缘和颧牙槽嵴可用微型钛板固定。
Objective: To introduce surgical correction of early old zygomatic fracture by open reduction. Methods: 7 old zygomatic fractures were operated post traumatically 2～3 months. Lateral orbital and inferior eyelid incisions were used in all cases and intraoral incision also were used in 2 cases. Fractures were fixed in the lateral orbital margin, inferior orbital margin and zygomatic alveolar ridge by mini and micro Ti plates. Bony defects of orbital floors were reconstructed using microplates in 2 cases. Results: Zygomatic deformities were corrected and dysfunctions of eye and oral were eliminated in all cases. No obvious skin scar was seen. Following up 1～3 years the results were satisfactory. Conclusion: Facial deformity and dysfunction in early old zygomatic fracture can be corrected by open reduction via facial and intraoral approach. Mini Ti plate must be used in lateral orbital margins for internal fixation to resist the contraction of masseter, and micro Ti plate could be used in inferior orbital margin and zygomatic alveolar ridge for stabilization. Eye function can be recovered by reconstruction of orbital floor defect using micro Ti plate.
