ABSTRACT

RESUMEN: Objetivo: El objetivo de este estudio fue determinar si existe equivalencia entre las medidas faciales obtenidas mediante antropometría facial directa y antropometría facial indirecta utilizando sistema de imagen digital en tres dimensiones en adultos jóvenes. Materiales y métodos: Estudio transversal descriptivo. La muestra consistió en 81 voluntarios (19-29 años). A cada uno se le realizó mediciones de 6 distancias faciales con el método antropométrico directo y 5 distancias faciales con el método fotogramétrico 3D. Se utilizaron los programas Excel 2013 y Stata14®. Se aplicó el test de Shapiro-Wilk, para establecer el tipo de distribución de los datos. Para los que presentaron distribución normal se aplicó t-Test; para aquellos con distribución no normal, se aplicó test de Mann-Whitney. Se comparó las mediciones obtenidas con ambos métodos. Resultados: Se compararon las 5 distancias faciales medidas con el método antropométrico directo con las 5 registradas mediante fotogrametría 3D y se determinó que no existe diferencia estadísticamente significativa entre los métodos utilizados. Hubo una medición que no pudo ser registrada con el método fotogramétrico 3D. Conclusión: La antropometría facial indirecta medida en imágenes 3D, entrega mediciones equivalentes a la antropometría facial directa.


ABSTRACT: Objective: The aim of this study was to determine if there is equivalence between facial measurements obtained through direct facial anthropometry and indirect facial anthropometry using a three-dimensional digital imaging system in young adults. Materials and methods: Descriptive cross-sectional study. The sample consisted of 81 volunteers (19-29 years). Each was measured with 6 facial distances with the direct anthropometric method and 5 facial distances with the 3D photogrammetric method. The programs Excel 2013 and Stata14® were used. The Shapiro-Wilk test was applied to establish the type of distribution of the data. For those with normal distribution, t-Test was applied; for those with non-normal distribution, a Mann-Whitney test was applied. The measurements obtained with both methods were compared. Results: We compared the 5 facial distances measured with the direct anthropometric method with the 5 recorded by 3D photogrammetry and it was determined that there is no statistically significant difference between the methods used. There was a measurement that could not be recorded with the 3D photogrammetric method. Conclusion: The indirect facial anthropometry measured in 3D images, provides measurements equivalent to direct facial anthropometry.
