QUANTITATIVE EVALUATION AND PERCEPTION OF FACIAL CHANGES AFTER ORAL LIPECTOMY
Photogrammetry, Lipectomy, Subcutaneous fat.
This study sought to identify whether there is a difference in the cheek region through three-dimensional photogrammetry after bilateral oral lipectomy. This is a quasi-experimental clinical trial on oral lipectomy. Fifteen patients were operated on, totaling 30 oral lipectomies. A photographic protocol for three-dimensional photogrammetry was performed in two operative stages, T0: preoperative and T1: 10 months postoperatively. The mouth opening, body weight, the amount of fat removed in grams and milliliters; and visual analogue pain scale, were collected. Through the Google® Form, dental specialists evaluated the photographs. The quantitative evaluation of the subzygomatic region was performed using the GOM inspect® program using a color map and millimeter measurements in the cheek region. Spearman's coefficient and the Wilcoxon test were used. There was a moderate negative correlation between the amount of fat removed on the right side and the tissue change that occurred in zone 2, with p <0.046, revealing a statistically significant difference. The Wilcoxon test revealed a statistically significant difference in all zones between T0 and T1. The professionals' success rate on T0 and T1 was 69.86%. Three-dimensional photogrammetry was able to quantify the changes in the cheek region after the oral lipectomy, which despite being millimetric, were perceived by professionals. The subzygomatic area in zone 2 and 5 appears to be the region that decreases the most after CAB removal.
