Assessment of nutritional anthropometric parameters in adult patients undergoing orthognathic surgery

Purpose: This paper reports the assessment of nutritional anthropometric parameters of three patients who were submitted to orthognathic surgery followed by intermaxillary fixation and liquid diet.\nCase description: This prospective case series describes the changes in nutritional parameters of three adult subjects aged 20 to 24 years, including one male and two females, who received elective orthognathic surgery followed by intermaxillary fixation with orthodontic elastics for 14 days. The hospitalized patients were instructed to go on a liquid diet with hypercaloric and hyperprotein intake. After discharge, the patients continued the liquid diet up to 28 days postoperatively. Data on weight loss, body mass index, triceps skinfold thickness, midarm circumference, and midarm muscle area were collected one week before surgery, one week after surgery, and four weeks after surgery. All three patients had severe weight loss (>2 % weight loss per week).\nConclusion: The interaction between nutritionist and oral surgeon is essential in order to plan an adequate dietary intervention after orthognathic surgery to minimize occasional weight loss.\nKey words: Adult; oral surgery; nutritional status; weight loss
