          Abstract

          RESUMEN El biotipo facial de una persona puede verse afectado debido a varios factores internos y externos durante el crecimiento y desarrollo de las estructuras óseas del cráneo y de la cara. El mentón forma parte de dichas estructuras y se proyecta en base a características típicas que definen los perfiles faciales de cada individuo; el objetivo de este trabajo fue conocer la proporcionalidad cefalométrica del mentón y su proyección anterior en adultos jóvenes andinos. Se realizó un estudio cuantitativo, de tipo correlacional con diseño documental-retrospectivo no experimental con una muestra de 384 radiografías laterales de cráneo. Los resultados permitieron estimar una correlación positiva moderada entre las variables de estudio. En conclusión, la presente investigación evidencia que el alto y ancho del mentón es directamente proporcional a su proyección anterior.

          ABSTRACT The facial biotype of a person can be affected due to several internal and external factors during the growth and development of the bony structures of the skull and face. The chin is part of these structures and is projected based on typical characteristics that define the facial profiles of each individual; the objective of this work was to know the cephalometric proportionality of the chin and its anterior projection in young Andean adults. A quantitative correlational study with a non-experimental documentary-retrospective design was carried out with a sample of 384 lateral skull radiographs. The results allowed estimating a moderate positive correlation between the study variables. In conclusion, the present investigation shows that the height and width of the chin is directly proportional to its anterior projection.

            Anthropometric proportions in the upper lip-lower lip-chin area of the lower face in young white adults.

            The relationships between measurements of the lower lip, chin, upper lip, and lower half and lower third of the face were studied. Fifteen new indices were formed with the help of eleven vertical linear, one horizontal linear, and two surface-arc measurements in the area. Neoclassic canons related to the lower face were not confirmed. On the average, the lower lip was 83% to 85% as large as the upper lip. The upper lip occupied one third of the lower face, while the lower lip occupied more than one third of the lower third of the face and the chin occupied the remainder. Skin covered 73.5% of the upper lip in males and 68% in females; it covered 63% of the lower lip in males and 61.1% in females. The remainder was covered by vermilion, more on the lower than on the upper lip and more protruding in females than in males. Proportion standards are a valuable contribution to the surface anatomy of the lower face of young white adults.

              Aesthetic alteration of the chin.

              Edward Lee (2013)
              Genioplasty, the alteration of the chin through either osseous manipulation or implant augmentation, is an integral component of aesthetic surgery of the face. When performed with proper preoperative assessment and technical execution, the results can harmonize and restore balance between skeletal, soft tissue, and dental components of the lower face. To this end, proper understanding of the underlying anatomy and the changes associated with movement of the chin, alone or in conjunction with formal orthognathic surgery, is paramount. The author presents pertinent points on proper assessment, treatment planning, and a description of the surgical technique, and discusses complications and outcomes to optimize outcome.
