The nasal form is one of the most important aspects in assessing the facial aesthetics. Several authors have described changes in the form and nasal dimensions attributable to race and gender. The purpose of this study was to analyze the presence of sexual dimorphism in various morphometric parameters of the nose in a group of Chilean adults. This study involved 180 adults Chilean volunteers, 90 males and 90 females, between the age of 18 and 30 years which were conducted measurements of 12 parameters using indirect anthropometry, based on photographs from the front, profile and the nasal base, standardized, prosecuted through the program Corel Draw Graphics Suite X3. Of the 12 dimensions nasal analyzed, significant differences were found between males and females in 9 of them. These results reinforce the need for analysis of nasal morphotype in our population, because its usefulness in surgery, forensic reconstruction and aesthetics.

De las 12 dimensiones nasales analizadas, se encontraron diferencias significativas entre hombres y mujeres en 9 de ellas. Estos resultados refuerzan la necesidad de realizar analisis del morfotipo nasal en nuestra poblacion, por su utilidad en cirugia, reconstruccion forense y estetica.
