Frequency of Infra Orbital Nerve Paresthesia Following Zygomati Comaxillary Complex Fractures Among Tertiary Care Hospital Patients in OMFS OPD

Objective: The objective of the study was to investigate the frequency of infraorbital nerve Paresthesia following ZMC fractures treated with open reduction and internal fixation. Material and Methods: This case series study, conducted at Mayo Hospital's Oral and Maxillofacial Surgery Department over six months, enrolled 75 cases using consecutive sampling. Surgical management included open reduction and internal fixation, with follow-up assessments at specified intervals. Data analysis was performed using SPSS for a comprehensive evaluation to document the frequency of infraorbital nerve Paresthesia and recovery outcomes post-ZMC fractures and surgical intervention. Results: In this study, the results revealed that 33.33% (n=25) were between 41-50 years being the majority of patients in this study, common age was calculated as 37.43+3.78 years, 62.67%(n=47) were male and 37.33% (n=28) were females, frequency of infraorbital nerve Paresthesia following ZMC fractures revealed in 70.67%(n=53) cases while 29.33%(n=22) had no findings of the morbidity, we recorded frequency of functional nerve recovery in patients with Paresthesia after performing open reduction and internal fixation among 53 cases who developed the morbidity and found 62.26% (n=33) who had functional nerve recovery while rest of 37.74%(n=20) had no recovery. Conclusion: The frequency of functional nerve recovery is high among patients with Paresthesia treated with open reduction and internal fixation.
