Aim: To evaluate the time taken for the recovery of the sensory loss after the maxillary and mandibular osteotomies and to evaluate the amount of sensory loss after these surgical procedures. Objectives: The objectives of the study were to assess and compare pre and post–operative extent of sensory loss and to assess the rate of recovery. Materials and method: Fifteen patients were enrolled for evaluation requiring orthognathic surgical procedures for the correction of jaw deformities. Pre and post–operative neurosensory evaluation was done using the neurosensory assessment methods at an interval of first week, first month and second month. Results: Statistically significant differences occurred at 1 week and 1 month, but over time nerve damage groups 1 and 2 recovered to similar levels. This study showed no statistical significance for age and NSD/recovery. Conclusion: On the basis of these results, we can say that the NSD rate is very low in surgical applications.
