Body fat composition and weight changes after double-jaw osteotomy.
Nutritional problems might be observed after surgical procedures. In this study, body weight and fat composition changes have been investigated in dentofacial deformity patients after the double-jaw osteotomy procedure. Thirty Angle class 3 patients operated on with double-jaw osteotomies during the period of March 2006 to July 2008 were included in the study. Interocclusal splints were applied continuously in the first 2 weeks after surgery, whereas intermittent splint was used for the next 2 weeks. Patients were analyzed before surgery and on the first month after surgery with the help of Tanita Composition Analyzer 310 bioimpedance method for weight, fat mass, and fat-free mass values. Results were evaluated statistically with the paired-sample test using SPSS version 13.0. Although significant results were obtained in female patients before surgery (weight [P = 0.011], body mass index [BMI; P = 0.012], fat mass [P = 0.010], and fat-free mass [P = 0.051, not significant]), none of the values were significant for male patients (P = 0.747, P = 0.747, P = 0.645, and P = 0.803, respectively). Weight gain was observed in 9 patients (30%). In contrast, weight gain was not seen in underweight patients. No sex differences in terms of weight gain/loss and fat composition have been observed. Interocclusal splint in female patients operated on with double-jaw osteotomies might cause nutritional deficiency in the first month after surgery. This eventually causes fat and weight loss, which may lead to poor wound healing and recovery later.
