“…Almost one third of the study population showed postinjury preoperative mental nerve hypoesthesia and over 45% suffered from purely postoperative hypoesthesia without pre-existing posttraumatic nerve injury. This finding correlates with other studies that analysed the IAN function after mandibular fractures (Schultze-Mosgau et al, 1999;Halpern et al, 2004;Renzi et al, 2004;Bede et al, 2012).…”

“…Literature shows postinjury (preoperative) hypoesthesia rates of up to 81% (Halpern et al, 2004;Bede et al, 2012). When preoperative alveolar nerve function is intact, the literature demonstrates postoperative hypoesthesia rates around 30% (Schultze-Mosgau et al, 1999;Renzi et al, 2004) caused by intraoperative irritation during ORIF. Recovery rates of the inferior alveolar nerve between 33% (Marchena et al, 1998) and 100% (Mayrink et al, 2013) have been published, which suggests a high potential for recovery.…”

a b s t r a c tPurpose: Mandibular fractures are amongst the most common facial fractures and are usually treated by open reduction and internal fixation (ORIF). Inferior alveolar nerve (IAN) injuries are seen frequently in mandibular fractures as well as after ORIF of these fractures due to the exposition and the close proximity of the nerve during fracture reduction. Therefore the continuity of the IAN can be disrupted. Permanent injury to the IAN can result in diminished quality of life. This retrospective study was designed to objectively analyse the incidence and the outcome of pre-and postoperative mental nerve hypoesthesia after ORIF of mandibular fractures. Results: 340 patients met the inclusion criteria. 27% of the study population presented with postinjury (preoperative) mental nerve hypoesthesia, 46% suffered from purely postoperative hypoesthesia and 27% showed no nerve damage. Complete recovery was seen in 70% of all cases, partial recovery in 20% of the cases and less than 10% suffered from a permanent (>12 months) IAN damage. Mandibular angle fractures were accompanied with significantly higher rates of hypoesthesia (79% vs. 68%). Recovery rate was significantly worse in older patients, when preoperative hypoesthesia was present (66% vs. 73%) and in patients with multiple fractures in proximity to the IAN (36% vs. 52%). Mandibular body fractures showed worse recovery rates than fractures that did not affect the body (44% vs. 52%).Conclusion: The present study shows that IAN injury is seen frequently in mandibular fractures. Mental nerve hypoesthesia may influence quality of life. Nerve continuity may not be preserved due to the initial trauma or may result as a postoperative complication. Nevertheless the results of this study show a high potential for full recovery.

“…The infraorbital nerve is injured directly by the fractured bone at the infraorbital groove/canal and/or by indirect contusion of the nerve bundle near the infraorbital foramen 23. Adults commonly have thinner soft tissue in the malar region than children,3 which may lead to vulnerability to indirect contusion of the bundle near the infraorbital foramen.…”

“…This is in contrast to previous data. Renzi et al reported on postoperative sensory disturbances at a rate of 54.4% in the non-displaced and 88.2% in the displaced fracture group (Renzi et al, 2004). Zachharides et al showed similar results with a significantly smaller number of sensibility disturbance in patients with non-displaced fractures (Zachariades et al, 1990).…”
