Abstract

The Japanese Society for Jaw Deformities performed a nationwide survey from 2006 to 2007 and the results were reported in 2008. In the last 10 years, new surgical procedures and medical devices have been developed and brought major changes to surgical orthodontic treatment. Accordingly, we need to assess the current status of surgical orthodontic treatment.<br>A nationwide survey of surgical orthodontic treatment between April 2017 and March 2018 was carried out and 99 surgical facilities and 64 orthodontic facilities were enrolled in the survey. The number of patients who received orthognathic surgery was 3,405, about 69％ of whom were diagnosed with mandibular protrusion. Before the surgery, 3D-simulation was performed for about 40％ of patients at both surgical and orthodontic facilities. Computer-aided design and computer-aided manufacturing （CAD/CAM） wafers were used at 12.1％ of surgical facilities and at 17.7％ of orthodontic facilities. Sagittal split ramus osteotomy （SSRO） was performed in 2,768 patients （85.5％） and Le FortⅠosteotomy in 1,829 patients （56.5％）. Blood loss during the surgery was reduced compared with that in the previous survey. Autologous blood transfusion tended to be performed in cases as necessary such as surgery for maxilla and anemia of the patient. Duration of intermaxillary fixation and hospital stay were also shortened. <br> This survey revealed the current status of surgical orthodontic treatment in Japan in comparison with the previous survey.
