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.

Objective: To compare the functional recovery of infraorbital nerve paresthesia following open reduction as compared to closed reduction in zygomaticomaxillary complex fracture management. Study Design: Randomized controlled trial. Place and Duration of Study: Oral and Maxillofacial Surgery Dept. Dentistry Section, Ayub Medical College & Teaching Hospital, Abbottabad from 1st April 2016 to 30th September 2016. Methodology: Eighty two patients of infraorbital nerve recovery were included. They were divided in two groups; group A was treated by closed reduction technique, and group B was treated by open reduction with internal fixation technique using mini plates. Permuted blocks of 6 were used to ensure equal representation in both groups. All patients were underwent surgical management within 1-7 days following trauma. Patients were assessed post-surgery for infraorbital nerve recovery. Results: There were 63.4% males and 36.6% females in group A while 60.9% males and 39.1% females were included in group B with mean age was 28.44±7.15 years in group A and 27.93±7.33 in group B respectively. 51.2% patients have infraorbial nerve recovery in group A while 65.8% have infraorbital nerve recovery in group B. Conclusion: Closed reduction approach was found to be the best reduction technique and open reduction was effective in terms of stability, prevention of relaps and functional recovery of infraorbital nerve injuries.

Abstract Background The aim of this study is to evaluate the postoperative stability of zygomaticomaxillary complex (ZMC) fractures according to the number of fixation sites and to investigate the direction of postoperative displacement of the unfixed part of the fractured segment. Methods This study was retrospectively performed on 38 patients who were treated by open reduction and internal fixation of ZMC fractures and were taken postoperative computed tomography (CT) between February 2012 and July 2019. The patients were classified into 3 groups: 1-point fixation, 2-point fixation, 3-point fixation according to the number of fixations. The postoperative displacement of the fractured segment was evaluated by the superimposition between postoperative CT and follow-up CT, and the postoperative stability according to the fixation sites was investigated through the amount of postoperative displacement. In addition, it was investigated in which direction the location of the fractured segment was changed in the unfixed fractured segment according to the fixation sites. Results The amount of postoperative displacement of the fractured segment was 0.75 ± 1.18 mm on average. In the postoperative displacement of the distal area according to the number of fixation of the fracture, there was no statistically significant difference in the amount of displacement of the fracture (p = 0.574). As for the direction of the change in the location of the fractured segment, 12 patients among 38 patients with the change in the location of the fractured segment were investigated, and the displacement in the medial direction (n = 11, 91.67%) was the most common in all three fixation methods. Conclusion In patients with a ZMC fracture who were treated by open reduction and internal fixation, the number of fixations did not make the difference in the postoperative displacement of the fracture. In addition, the fractured segment mainly changes in the medial direction after surgery, and this fact can be used as a reference for the reduction direction during surgery for the stable prognosis.

<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>
