Objective <p>The objectives of this study were to evaluate if there is correlation between the volume of the Bichat ball and gender, body mass index (BMI), skin color and age, to evaluate the accuracy of preoperative ultrasound in bichectomy, to calculate the average of fat volume obtained by bichectomy and compare it with the study of Bichat and how do these factors correlate with postoperative satisfaction and facial rejuvenation. </p> Methods <p>Twenty patients were selected for bichectomy and distributed into three groups according to BMI. Before the surgery, all of them underwent ultrasound examination of the Bichat ball, they were photographed and anthropometric facial measurements were taken. The statistical analysis of the data was analyzed using ANOVA, Paired ‘T,’ Pearson correlation, Tukey, Wilcoxon and Mann–Whitney test. </p> Results <p>Test results indicated that ultrasound fat volumes and those obtained by surgery have no statistical difference and, compared with the Bichat study, there is no statistically difference. There were no correlations between the fat volumes and the BMI, gender or skin color. The patient’s satisfaction was 100%. </p> Conclusion <p>There is no correlation between buccal fat pad volume and gender, body mass index, or ethnicity, but there is with age. The satisfaction rate achieved demonstrates that bichectomies provide satisfactory results. </p>
