Facial growth changes in a Colombian Mestizo population: An 18-year follow-up longitudinal study using linear mixed models.

Introduction: Currently, a standard of reference for longitudinal facial growth parameters for South American mestizos is lacking. Therefore, in this study, we describe an 18-year follow-up of craniofacial growth from 6 to 24 years of age in a Colombian mestizo population, and an analysis of facial growth beyond 18 years of age.

Methods: This 18-year follow-up longitudinal study was conducted in Medellín, Colombia.
