The survey consisted of questions that referred to a nationwide survey performed by the Japanese Society for Jaw Deformities. As a result, the number of patients who received orthognathic surgery was 1,579, about 68% of whom were diagnosed with mandibular protrusion. Sagittal split ramus osteotomy (SSRO) was performed in 1,388 patients (87.9%) and Le Fort I osteotomy (LF1) in 536 patients (33.9%). The average operation time was 163 minutes and the amount of bleeding was 172g in SSSO, and those in two-jaw surgery were 300 minutes and 434g respectively. There was a significant correlation between operation time and blood loss in two-jaw surgery (r=0.74, p<0.01). Autologous blood transfusion was performed in two-jaw surgery patients by all facilities. The average duration of hospital stay was 15 days but varied by more than twenty days depending on the facility.

Sakaue, K. Kurihara, Ryo Abe, T. Ono, I. Saito","doi":"10.5927/jjjd.29.237","DOIUrl":"https://doi.org/10.5927/jjjd.29.237","url":null,"abstract":"Purpose : Previous studies on masticatory function in patients with mandibular prognathism have examined various aspects such as occlusal contact area, mandibular movement, and masticatory muscle activity. However, there have been few reports on the relationship between objective masticatory performance and craniofacial morphology in patients with mandibular prognathism due to the lack of a quick and simple method. This study aimed to clarify the relationship between masticatory performance and craniofacial morphology for patients with mandibular prognathism by using a fully automatic system. Subjects and Methods : Ten patients with mandibular prognathism (age : 16.6±1.3 years) and 10 volunteers with individual normal occlusion (age : 24.1±2.6 years) as controls were enrolled in this study. At the initial examination, lateral cephalograms were taken and analyzed. Masticatory performance was assessed by a fully automatic measuring system (Tokyo-koden, Tokyo, Japan) using a testing gummy jelly (UHAMikakuto, Osaka, Japan). Chewing time was measured with a stopwatch. Occlusal contact area was measured using a silicone testing material and analyzing device (BiteEye, GC, Tokyo, Japan). Maximum bite force was also measured by using an occlusal force meter (Morita, Osaka, Japan). Wilcoxon's rank sum test was used for comparing the masticatory performance, occlusal contact area and maximum bite force between the two groups. Spearman's rank correlation coefficient was used to evaluate the relationship between masticatory performance and craniofacial morphology. Results : Masticatory performance, occlusal contact area and maximum bite force were significantly lower in the patient group than in the control group. These results suggest that remarkable skeletal discrepancy and lack of tooth contact in the anterior regions and lateral segments may yield a decrease in occlusal contact area, maximum bite force and masticatory performance. A negative correlation was found between masticatory performance and gonial angle and ANS-Me, whereas a positive correlation was found between masticatory performance and chewing time. These findings suggest that the load on the masticatory muscles was reduced in patients with mandibular prognathism due to a decrease in masticatory performance, resulting in the opening of the gonial angle which is the attachment area of the masseter muscle, and in the enlargement of anterior lower facial height.
