Neurosensory Assessment of Infraorbital Nerve Injury Following Unilateral Zygomaticomaxillary Complex Fracture

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.
