Objective: To assess the inferior alveolar nerve function post-trauma (post-injury) and post-surgery (open reduction and internal fixation). Methodology: Total 56 patients having fracture of angle of mandible were included. Inferior alveolar nerve function was assessed by Two-point discrimination method at post-injury (pre-operatively), and after mandibular fracture treatment with open reduction and internal fixation and at follow up visits i.e. at 1 st week, 4 th week, 8 th week, 12 th week

Results: There were 67.8% male and 32.2% female patients. Of which 30.2% patients aged 21 to 30 years, 51.9% aged 31 to 40 years, and 17.9% aged 41 to 50 years. It was observed that 58.9% patients had right sided fracture and 41.1% patients had left sided fracture. Preoperatively inferior alveolar nerve assessment showed intact in all patients. Postoperatively at 16 th week 91.1% were positive at lip and 89.3% were positive at chin. Conclusion: Fractures of angle of mandible play a major role in the neurosensory deficit of the Inferior Alveolar nerve. Fracture site was related to effects too. The IAN deficits do not affect by age and sex.
