Objective. The objective of this study was to evaluate the association between the presence of the hyoid triangle negative and oral breathing. Methods. We analyzed a total of 100 lateral teleradiographs, 50 belonging to patients with oral breathing and 50 with nasal breathing. Of these, 70% corresponded to female patients (n=70) and 30% to male patients (30). 59% corresponded to patients between 20 and 30 years, 21% between 10-20 years, 15% between 30-40 years and 5% between 40-50 years old. The inclusion criteria were clinical records of patients of both sexes between 15 and 50 years of age, who have profile teleradiographs and in which their type of breathing (oral or nasal) has been recorded. The exclusion criteria were clinical records of patients in whom the teleradiography is in digital format, with positioning or damaged errors or belonging to subjects who have diagnosed genetic s...
