Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Return of mandibular movements more quickly, in patients submitted to bimaxilar orthognathic surgery with mentoplasty, after phototherapy with low power laser. The mandibular movements will be measured in millimeters during passive opening, passive right and left laterality and active protrusion. These measurements will be performed with the aid of a digital caliper in the preoperative period and in the postoperative period of 7, 14, 30 and 60 days. Statistical tests will be applied to compare the groups.;Pain reduction in patients undergoing bimaxillary orthognathic surgery with mentoplasty after low power laser phototherapy. Prior to each laser therapy session, the EVA scale will be used to measure the pain intensity in the immediate postoperative period, 24, 48 hours and then 2 times a week until the nineteenth session is completed. These values ??will be annotated in standard tab will be applied statistical tests for comparison between groups.;Smaller amount of edema in patients submitted to bimaxilar orthognathic surgery with mentoplasty, after phototherapy with low power laser. Measurements of edema in millimeters with the use of a malleable ruler in the immediate postoperative period, 7, 14, 30 and 60 days, based on cephalometric points, will be evaluated: these are the distances between the corner of the eye and the gonion, between the tragus and the labial commissure and between the tragus and the pogonium of each patient. The right and left sides of both groups will also be evaluated, being the sum of the sides considered. These values ??will be annotated in standard tab, statistical tests will be applied to compare the groups. | — |
