Objective: This study aimed to classify and determine the prevalence of individuals with vertical alteration of facial relationships, according to the severity of discrepancy, especially individuals with long face pattern. Methods: The sample was composed of 5,020 individuals of Brazilian nationality, of both genders, aged 10 years to 16 years and 11 months, attending middle schools at the city of Bauru-SP, Brazil. Examination of facial morphology comprised direct observation of the face in frontal and lateral views, always with the lip at rest, aiming to identify individuals presenting vertical alteration of facial relationships. After identification, these individuals were scored, according to severity, into three subtypes, namely mild, moderate and severe. The prevalence of individuals with long face pattern considered only the individuals scored as subtypes moderate and severe. Results: There was prevalence of 34.94% of vertical alteration of facial relationships and 14.06% of long face pattern. Conclusions: The results obtained in this study revealed that the prevalence of vertical alteration of facial relationships and long face pattern was higher than that reported in the literature.
