Abstract: Purpose The purpose of this study was to evaluate patients' nutritional state after orthognathic surgery. Methods The subjects were 40 female patients with dentofacial deformity aged 17-33 years who were undergoing bilateral sagittal splitting ramus osteotomy. Twenty patients were treated with intermaxillary fixation, and 20 patients were treated without intermaxillary fixation. Age and body mass index (kg/m(2)) were assessed as physical factors, operation time, blood loss, and amount of mandibular movement with or without intermaxillary fixation were assessed as operation stress factors, and the following laboratory data, total protein, serum albumin, total cholesterol, total lymphocytes, and cholinesterase were assessed as nutritional state factors at 1 and 2 weeks after surgery. Statistical analysis was performed for body weight loss and relationship between body weight loss and examination factors. Results Body weight significantly decreased 2.3% at 1 week and 3.9% at 2 weeks after surgery rather than preoperation. All laboratory data except total lymphocyte were decreased at 1 week after surgery and still remained significantly decreased at 2 weeks after surgery. There was a statistically significant relationship between body weight loss at 1 week after surgery and operation time. Conclusions These results indicate that long operation time caused body weight loss in orthognathic surgery.
