    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.

    Introduction: Computed tomography has been increasingly used both to identify and to evaluate anatomy variations of nasal cavities that can lead to the development of sinusitis. Purpose: The purpose of the present study is to determine the incidence of mucosal abnormalities in paranasal sinuses found in CT scans of patients with symptons of sinusitis and analyze the correlation between sinusitis and presence of Haller's cell, concha bullosa and nasal septal deviation located in middle meatus. Study Design: Clinical retrospective. Material and Method: Paranasal sinus CT scans were obtained in 150 patients aged 13 years or more, from July 1999 to October 2001. The CT scans were performed in the Department of Radiology of Universidade Federal de São Paulo (UNIFESP) - Escola Paulista de Medicina. Patients with history of skull base or sinus surgery and tumor in these regions were excluded. Results: 70% of patients present mucosal abnormalities at least in one paranasal sinus. Maxillary sinusitis were observed in 52,7% of sinus, ethmoidal sinusitis in 28,0%, sphenoidal sinusitis in 13,0% and frontal sinusitis in 8,3%. Concha bullosa was observed in 33,3% of nasal cavities, nasal septal deviation (located in middle meatus) in 23,3% and Haller's cell in 9,3%. Conclusions: The most affected paranasal sinuses were: maxillary, ethmoid, sphenoid and frontal. Correlation between sinusitis and presence of Haller's cell, concha bullosa and nasal septal deviation (located in middle meatus) was not observed.
