Abstract
Objective: To compare the frequency of the recovery of infraorbital nerve injuryfollowing zygomatic complex fracture management with open reduction and close reduction.Study Design: Randomized controlled trail study. Setting: Oral & Maxillofacial SurgeryDepartment of Dentistry, Liaquat University Hospital, Jamshoro. Period: From 17th October2015 to 16th October 2016. Material and Methods: Total 168 patients with zygomatic complexfracture with infraorbital nerve injury were included and equally divided in Close (Group-A)and Open (Group-B) reduction. Neurosensory evaluation was done. The areas were examinedbilaterally anterior cheek, lateral side of the nose and upper lip. After 24 weeks if two successivepositive responses were obtain then result was called recovery. Descriptive statistics wereapplied. Stratification was done using Chi square test. Results: The mean duration of fracture ingroup A was 21.41±9.81 hours while in group B it was 20.65±9.11 hours. The assessment after24 weeks showed better results in Group B as compared with Group A. Recovery of infraorbitalnerve injury was observed 13.1% in group A and 94% in group B. Conclusion: The frequencyof recovery is high with open reduction as compared to closed reduction.
