    Introduction: Transverse maxillary atresia should be corrected as early as possible in the growth phase, with resources that provide skeletal changes, and one of the procedures widely addressed in the literature is rapid maxillary expansion (RME). Objective: Evaluate, in short term, the dentoskeletal effects of RME on maxillary and nasal dimensions using computed tomography images ( pre and post-RME at 6 months). Methods: Frontal norm computed tomography (CT) images of 30 patients ranging from 7 to 10 years old, mean age of 8.7 years, 18 males and 12 females, mouth breathers, who underwent RME. Linear measurements Pre (T1) and Post (T2) RME were performed, and all measurements were repeated by the same observer (intraobserver error) and by a second observer (interobserver error). Results: Comparing the results of the seven measures evaluated before RME (T1) and after RME (T2), there were significant differences, between T1 and T2, in the measures facial width, nasal height, nasal width, maxillary width, maxillary height and in the upper intermolar distance. Regarding the lower intermolar distance, there were no significant differences between T1 and T2. Facial width registered the strongest variation in the values of linear measurements between T1 and T2. Conclusion: After comparative analysis of the results obtained pre and post RME, we can conclude that the effects of rapid maxillary expansion, in short term, show a significant increase in facial width, nasal height, nasal width, maxillary width, maxillary height and upper intermolar distance.

    Qualidade de vida em pacientes submetidos à expansão rápida da maxila

    Introduction: This study evaluated the short-term volume changes in the nasomaxillary complex of mouth breathers after rapid maxillary expansion and correlated the outcomes with the patient’s quality of life. Objectives: Estimate whether rapid maxillary expansion can support on the improvement of the quality of life after treatment. Methods: A total of 35 mouth-breathing patients with maxillary constriction (mean age of 10.3 years) were evaluated by means of multslice computed tomography. Subjective symptoms were assessed with the use of a standardized quality of life questionnaire answered by patients and patients’ parents/legal guardians before rapid maxillary expansion and at 6 months later. Results: The total volume increased by 24,7% on average during the overall observation period. The nasomaxillary complex increased dimensionally, and the pretreatment subjective respiratory condition had improved significantly 6 months post rapid maxillary expansion. Conclusions: Rapid maxillary expansion results in a significant dimensional increase in the nasomaxillary complex. Furthermore, it also has a positive impact on the quality of life of mouth-breathing patients with maxillary constriction.
