The results of a national survey pertaining to the IVSO are presented and the findings are contrasted with the literature on the procedure. It was found that the IVSO is a popular procedure for mandibular setback, that the value of determining the mandibular divergence angle is equivocal, that the Stryker oscillating saw is the most popular instrument for performing the osteotomy, that most operators leave the segments unfixed, and that the intraoral approach to the correction of mandibular prognathism is preferred. There were no geographic trends noted.
