Increased Inflammatory Gene Expression in Masseter Muscle of an Orthognathic Surgery Subject with Obstructive Sleep Apnea
… The latter two conditions may prompt orthognathic correction. Past investigations have shown a genetic association with OSA. Given that masseter muscle influences skeletal malocclusion and is active during OSA, we investigated whether the expression of OSA-associated genes is altered …

The evaluation of the reproducibility of mock surgery using plaster model and lateral cephalometric radiograph in sagittal split ramus osteotomy
… to obtain a satisfactory esthetic result after orthognathic surgery, it is important not only to conduct accurate diagnosis and surgery planning but also to conduct the surgery as planned. In orthognathic surgical planning, after predicting outcome of surgery through lateral cephalometric …

The psychological and social implications of patient motivation and satisfaction with orthgnathic surgery
… predictor variables which identify perspective orthognathic surgical patients who may be poor surgical risks. The predictive qualities of four MMPI scales, two Bloom Sentence Completion scales, and seven Dental Inventory scales were used to identify presurgical, orthognathic patients who were …
