The analysis of 120 patients with zygoma fractures showed disturbances of sensibility in the field of the N. infraorbitalis in 84% and pathological statements of eyes in 20%. The re-examinations of 76 of these patients 0.5-4.5 years postoperative showed that more than the half of these patients, who were treated by only the bone-retractor have a redislocation of the zygoma, and 49% of all cases have permanent damages of the N. infraorbitalis. The reason for the damage of the nerve is not only the compression of the nerve for a short time by the dislocated zygoma but also regular present additional splits of the orbital floor, along the Canalis infraorbitalis. This statement is demonstrated in the present work by experimental examination.
对120例颧骨骨折患者的分析显示，84%的患者眶下神经区域感觉障碍，20%的患者眼部有病理表现。对其中76例患者术后0.5至4.5年的复查表明，仅采用骨牵开器治疗的患者中，超过一半出现颧骨再脱位，所有病例中有49%存在眶下神经永久性损伤。神经损伤的原因不仅是脱位的颧骨对神经的短期压迫，还包括沿眶下管的眶底经常出现的额外裂开。本研究通过实验检查证实了这一观点。
