Resumo
Este estudo tem por objetivo avaliar, em curto prazo, as possíveis alterações dimensionais do espaço orofaríngeo pré e pós-expansão rápida da maxila (ERM) por meio de tomografia computadorizada (TC) em pacientes respiradores orais. Material e método: Neste estudo retrospectivo selecionados 35 pacientes respiradores orais com atresia maxilar sendo 20 do gênero masculino e 15 do gênero feminino, com média de idade 9,6 anos, desvio padrão de 1,8 anos variando de 5 a 12 anos. Os exames de tomografia computadorizada (TC) foram realizados em dois momentos: pré-ERM (T1) e 6 meses após a finalização da fase ativa da ERM (T2). Após a seleção dos pacientes do banco de dados, as imagens tomográficas foram obtidas por meio do programa de manipulação de imagens e as comparações entre as TC iniciais (T1) e finais (T2) foram executadas com o auxilio do programa Dolphin Imaging Version 11.7 Preminun, de acordo com as estruturas e avaliações a serem realizadas. Os dados foram submetidos a análises do erro intra e inter-observador e testes estatísticos para comprovar a significância dos resultados obtidos. Resultados: Houve aumento significativo nas mensurações de área e volume da orofaringe. A área aumentou em 12,6% e o volume em 16,3% pós ERM. Em relação as medidas lineares de deslocamento da maxila houve aumento da distância ENACli em 1,45mm e da distância ENA-Ba em 1,31mm. Conclusões: Os resultados obtidos neste trabalho permitem concluir que a ERM promove, em curto prazo, deslocamento anterior da maxila com aumentos significativos da área e volume da orofaringe.
The purpose of this study is to evaluate, in the short term, possible changes of the oropharyngeal space before and after rapid expansion of the maxilla (ERM) by computed tomography (CT) in oral breathers patients. Material and method: In this retrospective study selected 35 oral breathers with maxillary atresia being 20 of the male gender and 15 of the female gender, with mean age 9.6 years, standard deviation of 1.8 years ranging from 5 to 12 years. The Computed tomography (CT) examinations were performed in two moments: pre-ERM (T1) and 6 months after the end of the active phase of ERM (T2). After selection of the patients from the database, the tomographic images were obtained by means of the image manipulation program and the comparisons between CT initial (T1) and final (T2) were performed with the aid of the Dolphin program Imaging Version 11.7 Prepend, according to the structures and evaluations to be carried out. The data were submitted to intra and inter-observer error analyzes and statistical tests to prove the significance of the results obtained. Results: There was a significant increase in the area and volume measurements of the oropharynx. The area increased by 12.6% and volume by 16.3% post MRE. Regarding the linear measurements of maxillary displacement showed an increase in the distance ENACli at 1.45mm and the ENA-Ba distance at 1.31mm. Conclusions: The results obtained in this work allow to conclude that ERM promotes, in the short term, displacement of the maxilla with significant increases in the area and volume of the oropharynx.
