Aim: This prospective study aim to determine the incidence and pattern of recovery of IAN and LN decits
after surgery while comparing which nerve, site, side, age group and type of impaction was most likely to
suffer from neurosensory disturbances and to evaluate the risk factors such as duration of surgery, proximity to inferior alveolar
canal, excessive hemorrhage, clinical observation of neurovascular bundle, contributing to these postoperative neurosensory
decits.
Materials&Methods: This study was conducted on 30 patients who underwent surgical removal of impacted mandibular third
molar between 2017-2019 in the Department of Oral and Maxillofacial Surgery, College of Dental Sciences, Davangere.
Clinically, all the patients underwent objective evaluation by using pin prick test, two-point discrimination and blunt test.
Sensory function was evaluated 1 week, 1, 3 and 6 months post-operatively. The areas that were evaluated are those supplied
by IAN and LN.
Result: The incidence of NSD in our study was 10%, the IAN 6.7% and LN decit 3.3%. No permanent NSD was observed in this
study. Statistically signicant association was found between excessive hemorrhage from the socket and NSD (p=0.009). No
signicant association was found between gender, age, side, type, difculty score and duration, observation of neurovascular
bundle during surgery and proximity of roots to the inferior alveolar canal with NSD.
