“…Orofacial surgery, such as extraction of an impacted tooth, placement of a dental implant, endodontic treatment, or mandibular fracture, occasionally causes injury to the inferior alveolar nerve (IAN), the third branch of the trigeminal nerve . Specifically, bilateral sagittal split osteotomy, the orthognathic procedure used to correct mandibular deformities, frequently induces neurosensory disturbance in the orofacial regions innervated by the IAN, necessitating therapeutic interventions for the sensory abnormality .…”

Inferior alveolar nerve (IAN) injury, which is frequently caused by orofacial surgery or trauma, induces sensory loss in orofacial regions innervated by the IAN. However, no effective treatment for orofacial sensory loss currently exists. We determined whether sensory loss in facial skin above the mental foramen following IAN transection was recovered by exposure of the transected IAN to low-intensity pulsed ultrasound (LIPUS). Inferior alveolar nerve transection (IANX) was performed in 7-wk-old male Sprague-Dawley rats. On day 7 after IANX, the effect of daily LIPUS (from day 0) on the transected IAN, in terms of sensitivity to mechanical stimulation of the facial skin above the mental foramen, was examined. Moreover, the number of trigeminal ganglion (TG) neurons innervating the facial skin above the mental foramen of rats with IANX treated daily with LIPUS was counted using the retrograde neurotracing technique. Daily exposure of the transected IAN to LIPUS significantly promoted recovery of the head-withdrawal threshold in response to mechanical stimulation of the facial skin above the mental foramen, and the number of TG neurons innervating the facial skin above mental foramen was significantly increased in rats with IANX treated daily with LIPUS compared with sham or LIPUS-unexposed rats. Daily treatment of stumps of the transected IAN with LIPUS facilitated morphological and functional regeneration, suggesting that LIPUS is an effective and novel therapy for IAN injury.

“…When the nerve is exposed to direct or indirect surgical trauma, it presents as bothersome paresthesia which extends over a variable period of time based on the severity of nerve injury. 9 , 10 , 11 Song et al. 12 established that there was a 7 fold increase in risk of postoperative mental nerve paresthesia with surgeons who had less than 3 years of surgical experience.…”

Purpose The purpose of the study is to compare the surgical access and post-operative outcome of two intra-oral incisions used for approaching a mandibular body fracture. Methods This clinical trial involved 60 patients with mandibular body fractures who were randomly allocated to control and study groups. The fractures were approached using the routine vestibular incision in the control group and crevicular incision with vertical release in the study group. The effects of incision design on the post-surgical outcome variables like swelling, trismus, paresthesia, wound healing and gingival recession were statistically analysed with non-parametric tests by using SPSS 22.0 software. Comparison of continuous variables between the groups and time points was done using Mann Whitney test and Friedman test respectively. Chi-square test was used to compare proportions between groups. Dunn's test with Bonferroni correction was used for pair wise comparisons. Results The study group demonstrated favourable surgical outcome in the immediate postoperative phase as compared to the control group. The difference in mouth opening, swelling and neurosensory impairment between the two groups was found to be statistically significant ( p < 0.05). Conclusion Crevicular incision was found to be an ideal alternative to vestibular incision in achieving surgical access and fixation of mandibular body fractures with reduction in postoperative patient discomfort and better surgical outcome.

“…Incorrect plate or screw positioning can result in dental injury or damage to the inferior alveolar nerve (IAN). Improper placement of hardware may explain some of the reported incidence of sensory disturbance (32%–72%) after internal fixation of fractures involving the IAN‐bearing mandible . In order to minimize these types of postoperative complications, surgeons must select the correct plate in terms of size and contour, and position it in a precise location for anatomic rigid or semirigid fixation while avoiding nearby structures.…”
