    Introduction: Maxillary atresia is a skeletal condition characterized by a transversal growth deficiency of the upper arch, with high prevalence in childhood, which demand intervention as early as it is possible, since it may be associated with breathing disorders, in some cases. Objectives: This study had the purpose to evaluate the dimensional changes of the nasal cavity on its height, width and volume previously and after Orthopedic Maxillary Expansion (OME) in mouth-breathing patients. Method: To this research, 18 patients were selected with clinical diagnosis of maxillary transversal deficiency and treated with OME, at the ambulatory of the Mouth Breather Center of the Pediatric Otorhinolaryngology department of the Federal University of São Paulo, 9 (50.0%) were male, with average age of 9.6 years old, with range between 6.4 and 14.2 years, with Standard Deviation of 2.6 years prior to the OME, the remaining 9 individual (50%), were females, with average age of 9.4 years old, ranging from 6.4 and 12.4 years, with Standard Deviation of 2.1 years prior to de OME. The included patients went through two facial Computed Tomography (CT) exam, previously and also 3 months after of the end of the active phase of the OME, and measurement of nasal height, width and volume where obtained through the software Implantviewer ® version 2.817 and the software for image treatment, Dolphing® Imaging version 11.7. Results: The results showed a statistically significant increase of nasal height previous and after OME, from 43.58 mm and 46.00 mm. The average nasal width prior to the OME was 21.7mm and 23.73mm after. The nasal volume increased from 33764.9 mm3 to 37932.5 mm3 after the treatment with OME. Conclusion: Based on the results, the Orthopedic Maxillary Expansion leads to an increase of the tested nasal characteristics.
