Abstract
Objective: To assess the mechanism of injury and type of fracture and association with type of morbidity due to of infra orbital
nerve lesions, in patients with zygomatico-maxillary bone complex fracture.
Study Design: Cross sectional Observational study
Place and Duration: Department of Oral and Maxillofacial Surgery, Nishtar Institute of Dentistry, Multan from 15th January 2019 to
15th May 2019.
Methodology: Patients presented within 14 days of trauma with isolated unilateral zygomatico- maxillary complex fracture were
studied. Radiological examination was carried out in the form of occipito-mental view 300 submento-vertex views to assess the type
of fracture. To confirm the type of nerve injury, patients detailed history, mode of injury and examination was carried out to detect
infra orbital nerve injury and morbidities.
Results: A total of 215 patients were studied from both genders between ages 18-50 years. Mean age was 28.465 ± 7.60 years
and mean duration of fracture was 5.507 ± 2.50 days. Majority of patients were males (88.4%). Road traffic accident in 42.3%, fall
36.3% and Interpersonal violence in 21.4% were the major mode of injuries. Non displaced fractures were 13%, Displaced 29.3%
and Comminuted 57.7%. No infra orbital nerve injury was in 14.9%, Paresthesia in 14.4%, Hyperalgesia 3.3% and Hypoalgesia was in
67.4%.
Conclusion: Compression of infra orbital nerve leading to paresthesia was more common in displaced fractures of zygomaticomaxillary bone complex.
