This is a cross-sectional study with a quantitative approach and a descriptive-retrospective design. The population consisted of 1500 radiographs and lateral photographs of mestizo Peruvians aged 18 to 40 years from the Radiological Center Imágenes between 2015 and 2017. Using inclusion and exclusion criteria, 60 participants were randomly selected (30 men and 30 women). Measurements were taken using the Nemoceph software, and the data was recorded in a data collection sheet and processed with SPSS v26. Normal distribution and variance homogeneity were determined (Shapiro-Wilk). The Student’s t-test was applied with a 95% confidence level. Statistically significant differences (p<0.05) were found in 3 of the 5 measurements of the Powell analysis: Naso Frontal Angle, Naso Mental Angle, and Mental Cervical Angle with p-values of 0.001, 0.04, and 0.001, respectively. Statistically significant differences were also found in all 7 measurements of the Legan and Burstone analysis: Facial Convexity Angle, Mandibular Protrusion, Maxillary Protrusion, Vertical Height Ratio, Neck Angle and Lower Third of the Face, Vertical Height and Depth Ratio of Lower Face, and Naso Labial Angle, with p-values of 0.001, 0.001, 0.001, 0.02, 0.001, 0.001, and 0.03, respectively. Additionally, significant statistical differences were found in the soft tissue profile of mestizo Peruvians evaluated using the Powell, Legan, and Burstone analysis by sex.
