Brief Summary

The bilateral sagittal split osteotomy (BSSO) of the mandible is one of the most used surgical techniques to achieve a harmonious jaw relation in the context of orthognathic surgery. Nevertheless, one of its main complications is neurosensory damage to the inferior alveolar nerve, which can cause severe impact in the quality of life on patients who suffer from it permanently. The purpose of this randomized clinical trial is to provide rigorous scientific evidence of the pharmacological effect of 1) Melatonin, 2) combination uridine triphosphate (UTP), cytidine monophosphate (CMP), and hydroxycobalamin (UTP/CMP/hydroxycobalamin) and 3) hydroxycobalamin regarding neurosensory disturbances incidence and persistence after BSSO.
