Sexual dimorphism of the maxillary sinuses through three-dimensional morphometric analysis in a high Andean population of Peru

Abstract

Introduction: sexual dimorphism is based on the differences and characteristics characteristic of both sexes in the same species.Objective: the purpose of this research was to determine the sexual dimorphism of the maxillary breasts of patients between 18 and 60 years of age from a high Andean population of Peru that were analyzed with Cone Beam Tomography.Methods: the following research had a descriptive, observational, cross-sectional and retrospective scope; the sample consisted of 190 Cone Beam tomographies of patients between 18 and 60 years of age of both sexes, where 380 maxillary sinuses were analyzed, in which the sexual dimorphism of the maxillary sinuses in height, width, length and volume were determined.Results: sexual dimorphism is greater in the male gender with respect to the female gender, volume was the best discriminating parameter of the right maxillary sinus that could be used to study sexual dimorphism with a total accuracy of 82,6 %, 88,1 % respectively, followed by width with an accuracy of 74,2 % on both sides, with a lower percentage was found to height with an accuracy of 69,5 % and 72,1 % respectively, length with an accuracy of 67,9 %, 68,4 % respectively.Conclusion: it was determined that sexual dimorphism shows higher values in the male sex as opposed to the female sex
