MAIA, Francisco Paulo Araújo et al. Neurosensory disturbances of the inferior alveolar nerve after intraoral vertical ramus osteotomy. Rev. Bras. Odontol. []. 2014, 71, 1, pp. 04-09. ISSN 1984-3747.

The aim of this study was to evaluate the impairment in the inferior alveolar nerve (IAN) after performing the intraoral vertical ramus osteotomy (IVRO) for the correction of mandibular prognathism, and compare with the literature reports. The sample was composed of ten patients, randomly chosen, undergoing OVIO, associated or not to the maxillary osteotomy. There were no cases of impairment to the IAN after one year of follow-up. The OVIO proved to be a safe and predictable surgical technique as long as its peculiarities are respected.
