The mean of this study was to determinate the differences between lip thickness and lip projection in mesofacial and brachyfacial patients of a Mexican population using the Arnett & Bergman cephalometric analysis. 120 cephalograms were evaluated using linear and angular measurements of the soft tissue analysis. In this study it was evaluated. occlusal plane with the upper incisive, occlusal plane with the upper incisive, interincisal angle, upper and lower lip thickness, nasolabial angle, interlabial gap, upper and lower lip projection and true vertical plane from nasion-menton. The ANOVA test was performed using Minitab (15 version) statistical analysis software to indicate the differences between the groups. No statistical significance was found in the occlusal plane with the upper and lower incisive, interincisal angle, nasolabial angle, interlabial gap and upper and lower lip projection. Statistical significance was found in women. upper lip thickness (p [less than or equal to] 0.007), lower lip thickness (p [less than or equal to] 0.001) and true vertical plane from nasion-menton (p [less than or equal to] 0.001) and a statistical significance in men, lower lip thickness (p [less than or equal to] 0.033), lower lip projection (p [less than or equal to] 0.039) and true vertical plane from nasion-menton (p [less than or equal to] 0.001). This measurement shows soft tissue differences between the facial growth patterns. A lip thickness difference was found between mesofacial and brachyfacial individuals. KEY WORDS: Soft tissue analysis; Lip thickness; Lip projection. El objetivo fue determinar las diferencias de grosor y proyeccion labial en hombres y mujeres mesofaciales y braquifaciales mexicanos a traves del analisis de Arnett & Bergman. Se evaluaron 120 radiografias laterales de craneo usando mediciones lineales y angulares de la cefalometria de tejidos blandos. Se evaluaron las dimensiones: plano oclusal, angulo interincisal, grosor del labio superior e inferior, angulo nasolabial, gap interlabial, proyeccion del labio superior e inferior, plano vertical nasion-menton. Para el analisis estadistico se realizo una prueba ANOVA usando el software minitab version 15 para determinar las diferencias entre los grupos. No se encontraron diferencias estadisticamente significativas en el plano oclusal del incisivo superior e inferior, en el angulo interincisal, angulo nasolabial, gap interlabial y proyecciones de labio superior e inferior. Se encontraron dife
