Neurosensory Assessment of Infraorbital Nerve Injury Following Unilateral Zygomaticomaxillary Complex Fracture

We aimed to assess the difference in the recovery pattern of branches of infraorbital nerve paraesthesia after zygomaticomaxillary complex (ZMC) fracture in both surgically and non-surgically managed patients.
A prospective, observational study involving 31 patients with unilateral ZMC fracture - 15 in the surgical group (Group A) and 16 in the nonsurgical group (Group B) was evaluated. These patients were assessed at the time of injury, 3-months follow-up, and 6-months follow-up for the sensory function of the infraorbital nerve. The assessment of paraesthesia was performed by cotton wisp test, light touch monofilament test, and the cold thermal test
A statistically significant improvement was noted on both 3 and 6 months follow-up in the malar region in group A. Other statistically significant improvements were noted only on 6 months follow-up in the infraorbital region in group A. On the 2-point discrimination test, all the facial regions showed significant improvement in both the groups over 3 months and 6 months of follow-up.

本研究旨在评估颧骨颧弓复合体（ZMC）骨折后，无论是手术还是非手术治疗的患者，眶下神经感觉异常恢复模式的差异。该研究为一项前瞻性观察性研究，纳入了31名单侧ZMC骨折患者，其中手术组（A组）15例，非手术组（B组）16例。对患者于受伤时、3个月随访以及6个月随访时的眶下神经感觉功能进行了评估。感觉异常的评估通过棉絮试验、轻触单丝试验和冷热试验进行。在A组中，在3个月和6个月的随访中，颧部区域均观察到统计学上显著的改善。在其他统计学上显著的改善仅见于A组眶下区域6个月随访时。在两点辨别测试中，两组患者在接受3个月和6个月随访后，所有面部区域均显示出显著的改善。本Excel表中所用代码如下：
