ABSTRACT

Aim:

Daily energy requirements increase after maxillofacial surgery.Along with this, patients experience nutritional problems because of long-time fluid or soft-diet feeding after a jaw surgery. Both of them can be resulted with malnutrition. In this study, we aimed to study the effect of individualized nutrition programs on nutritional parameters in patients having an orthognathic surgery

Methods:

A total of 14 patients who underwent orthognathic surgery were included in this study. Patients were evaluated just before the surgery and at postoperative days 7 and 21. Nutritional status was assessed by using the bioelectrical impedance method and also laboratory parameters (albumin, prealbumin, C-Reactive Protein and lymphocyte count). A diet schedule and calculated caloric requirement plan was prepared for each patient according to body composition analysis results. Measurements were analyzed using the Freidman test and Bonferroni-corrected Mann-Whitney U test

Results:

There was no significant difference between preoperative and postoperative body mass index values. A significant decrease in prealbumin (mean 4.7mg/dL) and albumin levels (mean 0.9mg/dL) and increase in C-reactive protein (mean: 38.1mg/L) level were seen at day 7. According to body composition analysis no significant differences were found in the means of fat weight, skeletal muscle weight and intracellular-extracellular water distribution at postoperative days 7 and 21

Conclusion:

Despite of other few reports regarding significant decrease in body weight after orthognathic surgery, no significant differences in body weight, fat, muscle and mineral composition of body and nutritional parameters in blood were seen in our study. We thought that individualized nutritional programs were effective to meet the nutritional needs of orthognathic surgery patients
