摘    要:目的 比较不同类型颧上颌复合体(zygomaticomaxillary complex,ZMC)骨折后眶下神经的损伤情况。方法 参照经典Zingg分类法,对2015年收治的70例单侧ZMC骨折进行分类,并测定其患侧与健侧眶下神经支配区皮肤的痛阈及两点辨别觉。利用不对称指数(asymmetry index,AI)对眶下神经损伤情况进行比较。应用SPSS19.0软件包对数据进行统计学分析。结果 70例ZMC骨折患者患侧眶下神经支配区均有不同程度感觉异常。对痛阈的测定结果显示,不同骨折类型间眶下神经损伤程度存在显著差异(P<0.05);两点辨别觉测定结果显示,B型与C型较A型骨折神经损伤程度更严重(P<0.05),B型与C型骨折间神经损伤无显著差异。结论 ZMC骨折容易引起眶下神经损伤, B型骨折患者神经损伤情况最重, A型骨折神经损伤最轻。

Abstract:PURPOSE: To investigate the association between infraorbital nerve sensory disturbances and zygomaticomaxillary complex (ZMC) fracture patterns. METHODS: Seventy patients with isolated unilateral ZMC fractures were examined on both uninjured and affected sides by using pain threshold test and two-points discrimination test. The fractures were classified according to classic Zingg's classification. Injury of the infraorbital nerve was expressed as asymmetry index (AI). SPSS19.0 software package was used for statistical analysis. RESULTS: The results suggested that neurosensory disturbance was present in all 70 patients with ZMC fracture. In the test of pain threshold, infraorbital nerve injury severity was different among different fracture patterns (P<0.05). Two-points discrimination test showed that infraorbital nerve injury was more severe in type B and C than in type A (P<0.05), but the difference between B and C was not significant. CONCLUSIONS: Infraorbital nerve injury is a common complication of ZMC fracture, type B fracture has the highest grade of nerve damage, while type A fracture has the lowest grade of nerve damage.
Keywords:Zygomaticomaxillary complex fractures  Zingg's classification  Infraorbital nerve  Pain threshold  Two-points discrimination
