A study of morbodities related to infraorbital nerve injury due to zygomatico-maxillary bone fractures.
Isra Med J Jan ;12(2):83-6.

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.
