INFRAORBITAL NERVE INJURY

ASSESSMENT OF RECOVERY FOLLOWING OPEN AND CLOSE TREATMENT METHODS IN ZYGOMATIC COMPLEX FRACTURE

Abstract

Objective: To compare the frequency of the recovery of infraorbital nerve injury
following zygomatic complex fracture management with open reduction and close reduction.
Study Design: Randomized controlled trail study. Setting: Oral & Maxillofacial Surgery
Department of Dentistry, Liaquat University Hospital, Jamshoro. Period: From 17th October
2015 to 16th October 2016. Material and Methods: Total 168 patients with zygomatic complex
fracture 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 examined
bilaterally anterior cheek, lateral side of the nose and upper lip. After 24 weeks if two successive
positive responses were obtain then result was called recovery. Descriptive statistics were
applied. Stratification was done using Chi square test. Results: The mean duration of fracture in
group A was 21.41±9.81 hours while in group B it was 20.65±9.11 hours. The assessment after
24 weeks showed better results in Group B as compared with Group A. Recovery of infraorbital
nerve injury was observed 13.1% in group A and 94% in group B. Conclusion: The frequency
of recovery is high with open reduction as compared to closed reduction.
