Nasal obstruction (NO) is a common symptom present in 25% of the general population, which significantly interferes with the quality of life. The different facial profiles and malocclusion patterns could be associated with the degree of NO. In order to evaluate the nasal function in patients with different facial morphology patterns, the authors developed a prospective study in which 88 patients from a dentofacial deformities center were included. These patients were submitted to fibrorhinoscopy (Mashida, ENT PIII) with a 3.2-mm cannula under topical anesthesia to evaluate septal deviation, inferior and medium turbinates, and pharyngeal tonsils. The 88 patients included in the study were divided into 3 groups according to the classification of the facial profile, distributed as follows: 32 class I, 28 class II, and 28 class III; the data collected was statistically analyzed by analysis of variance and the results are shown. The patients included in this study presented similar prevalence of NO with the reduction of airway function efficiency. Although it was not a statistically different, the group II presented higher mean Nasal Obstruction Syndrome Evaluation scores.
