Abstract

Aim: The aim of the study is to determine the prevalence and recovery of infraorbital nerve sensory disturbances following the occurrence of zygomatic complex fractures.

Method: 61 patients from 2017 to 2019 who sustained zygomatic complex fractures and received treatment at a tertiary care centre in Malaysia were recruited for this study. The patterns of the fractures were reviewed and classified using the classification proposed by Zingg et al. Infraorbital nerve disturbances were recorded before and after treatment.

Result: 21 patients (34.4%) developed infraorbital nerve disturbances following trauma. 16 patients (26.2%) were treated via open reduction and internal fixation (ORIF) and 5 patients (8.2%) via conservative management. Patients who sustained Type C fractures that reported infraorbital nerve disturbances numbered 11 cases (37.9%) while Type B fractures numbered 10 cases (41.7%). After 3 months, 11 patients treated via ORIF and 1 patient treated conservatively reported recovery of the infraorbital nerve sensation.

Conclusion: The more serious the fracture displacement is, the worse the prognosis with regard to infraorbital nerve recovery. ORIF of severe fracture displacement may improve outcome of infraorbital nerve recovery following zygomatic complex trauma.
