Mandibular fractures are a common type of injuries of the facial bones. Most of them affect the angle and body of the mandible in the areas innervated by the inferior alveolar nerve (IAN). Inpatients of maxillofacial units often lack health literacy; therefore, the aim of our study was to improve the effect of treatment in patients with mandibular fractures and IAN injuries by motivating patients toward a healthy lifestyle and by pioneering the use of therapeutic agents Mexicor and Combilipen in the standard regimen.
