The objective of this study is to evaluate the influence of the atypical swallowing habit on craniofacial pattern and on mandible morphology by means of the Cephalometric Analysis of McNamara. The sample was consisted of 100 lateral telerradiographs related to leukoderm male and female Brazilian youths, aging from 8 (eight) to 13 (thirteen) years old, where 50 individuals with atypical swallowing and 50 individuals with normal swallowing, all them patients of the Specialization in Orthodontics Clinic of the Dentistry College of the University of Passo Fundo. First, medical forms, which data were used as base for the classification of the control group and the group to be studied, were evaluated. After that, telerradiographs were selected and the Cephalometric Analysis of McNamara was achieved, in which the relationship of the maxilla with the cranium base, the relationship between maxilla and mandible, facial antero-inferior height, mandible plane angle, facial axis and the airway analysis were evaluated. The results were submitted to statistical analysis through Student t-test (p < 0.05) and exposed in comparative table, showing that no measures evaluated presented statistical significance value. In conclusion, the atypical swallowing habit can influence the alterations of the craniofacial pattern and the mandible morphology, not being the unique and determinant value to these alterations.
