University approach to nasal projection in adult individuals with different facial patterns in Cuenca, Ecuador

Abstract

The nose is the central part of the face, it is important that it is in balance with the other facial elements such as lips and chin, since they provide facial esthetics to each individual. It was evaluated nasal projection in adult individuals with different facial patterns in Cuenca-Ecuador. It was a descriptive cross-sectional study, it was carried out nasal and cephalometric tracings were made in the digital program AutoCAD in 140 cephalometric radiographs in digital format of individuals between 18 and 45 years old. According to the facial type, four groups were formed: low, medium-low, medium-high and high The normal distribution of the data was evaluated, and the association was established using the Kruskal-Wallis test or one-way ANOVA depending on the normality of the data, and the post hoc Tukey test. Values below p<0.05 were considered statistically significant. Significant differences were found in the convexity of the lower dorsum, columella convexity, and soft tissue facial convexity. In the mid-high and high facial pattern, a difference in lower dorsum convexity was determined when compared between groups. Elongated faces presented a convex profile, greater convexity of the lower dorsum, and smaller columella dimension, while short faces showed a concave profile, lesser convexity of the lower dorsum, and larger columella.
