Background and Purpose: Fractures of mandible frequently result in inferior alveolar nerve (IAN) injury and altered neurosensory function. This may be due to primary injury which lies in the line of fracture or a secondary insult due to manipulation at the time of fixation of the fracture. The purpose of this study is to measure post-injury/pre-treatment and immediate postoperative IAN sensory changes during the management of mandibular fractures and to identify risk factors for adverse perioperative IAN neurosensory changes. Materials and Methods: This study was conducted on the patients admitted in the Department of Oral and Maxillofacial Surgery, Bapuji Dental College and Hospital, Davangere. Fracture location was divided into two categories as Fracture location 1 (L1) which was between the lingula and mental foramen which place the IAN at direct risk for injury & Fracture location 2 (L2) included fractures distal to the mental foramen. In these cases, the IAN is out of the bone and hence at risk for injury indirectly (i.e., via soft tissue trauma). Treatment was rendered in a non-randomized manner by the surgeon. To assess neurosensory function, protocol described by Zuniga and Essick will be used. All the required parameters were measured & recorded pre-operatively & post-operatively. Results: The results of the present study showed that fracture displacement of more than 4 mm at L1 site & excess manipulation of soft tissues at L2 site was associated with Significant Neurosensory Deficit. Conclusion: Identifying the factors associated with poor long term outcome of NSD would need a larger sample size and detailed documentation of the use of various diagnostic tools to arrive at a conclusive observation.
