Objectives: To associate maxillary atresia with facial types, investigating whether dimorphism occurs between males and females and evaluating the percentage of such dimorphism according to gender and facial type. Methods: Initially, the sample consisted of 258 lateral cephalometric radiographs. After analyzing Ricketts’ VERT index, 108 radiographs were excluded for not meeting the selection criteria. Therefore, the sample consisted of 150 lateral cephalometric radiographs and 150 models of 150 Caucasian individuals aged 14 years to 18 years and 11 months, regardless of malocclusion type. The sample was divided into 50 mesofacials, 50 brachyfacials and 50 dolichofacials. The Schwarz’s analysis was applied to all 150 models. Results: The presence of maxillary atresia in the sample consisted of 64% in dolichofacials, 58% in brachyfacials and 52% in mesofacials. Conclusions: There was no evidence showing that atresia is in any way associated with facial type. Gender dimorphism was proportionally greater in dolichofacial males while females did not exhibit different proportions.
