Background: Maxillofacial injuries are on the rise and the etiology of maxillofacial injuries varies from one country to another because of social, cultural and environmental factors. Road traffic accidents (RTAs) are still the most common cause of maxillofacial injuries. Nerve injury following fracture may involve traction, pressure, ischemia, inflammation and physical damage; therefore fractures of Zygomaticomaxillary complex (ZMC) are characterized by sensory neuropathy in the area of innervation of infra-orbital nerve both as presenting symptom and as a postop complication. The objectives of the study were to investigate the frequency of infra-orbital nerve paresthesia following ZMC fractures and determine the frequency of functional nerve recovery in patients with paresthesia treated with open reduction and internal fixation.Methods: Patients (n = 75) qualifying our inclusion criteria were selected, examined, reduced by surgery and followed up.Results: A total of 75 patients were included in the study with male: female ratio of 5:3. Mean age was 37.43±3.78 years, with majority of patients (72 %) presenting with RTAs. Infra-orbital nerve paraesthesia was found to be positive in 70.67% (n = 53) patients with 62.26% (n = 33) patients with functional nerve recovery after 3 months.Conclusions: Prognosis of infra-orbital nerve recovery after a Zygomaticomaxillary complex fracture can be enhanced by open reduction and internal fixation.

<p class="abstract"><strong>Background:</strong> Zygomaticomaxillary complex (ZMC) fracture is quite commonly seen fracture in the road side accidents (RTA). It is the second most common fracture after nasal bone fractures. Infraorbital nerve is almost always involved with ZMC fractures which can be treated with open reduction and internal fixation or closed reduction.</p><p class="abstract"><strong>Methods:</strong> The aim of this study was to compare the recovery of infraorbital nerve paresthesia following open reduction and internal fixation verses closed reduction in the management of ZMC fractures.  </p><p class="abstract"><strong>Results:</strong> Two groups with n=50 patients each, qualifying our inclusion criteria were selected, examined, reduced by open and closed reduction respectively and followed up.</p><p class="abstract"><strong>Conclusions:</strong> The functional infraorbital nerve recovery was found among 74% patients those who underwent open reduction and internal fixation. While the patients treated with closed reduction the functional nerve recovery was seen in 52%.</p>

Study Objectives: To evaluate the efficacy of post-operative antibiotic prophylaxis in mandibular fractures. Study Design and Settings: It was a randomized controlled trial carried at of Department of Oral & Maxillofacial Surgery Akhtar Saeed Medical & Dental College Lahore from January 2021 to June 2021. Patients and Methods: After accepting to be enrolled in the study 50 patients with mandible fractures were randomly assigned into two groups Group A and Group B respectively. From admission until 24 hours post-operatively, all patients were given prophylactic antibiotic. The patients were than evaluated for evidence of infection at 6 weeks post-operatively.. Results of the Study: The age incidence varied from 18-60 years. The maximum number of patients belongs to age group 20-30 years. In a total of 50 patients, 45 male and 5 female patients were enrolled for the study. 4 of 25 patients in group A (16%) and 3 of 25 patients in group B (12%) reported with infection during follow-up. No statistically significant difference in the incidence of infection was noted between the groups Conclusion: In this study it was concluded that 1 day post-operative antibiotic is adequate to prevent post-operative infection in uncomplicated mandible fractures. The extended use of post-operative prophylactic antibiotic does not affect the incidence of infection in uncomplicated mandible fracture.
