“…The decrease in nasal resistance and the expansion of the pharyngeal lumen, especially in the LL, might help prevent OSAS. 29,30 Regarding the dental results obtained in the present study, an expansion of 0.65 cm was observed between the first premolars, whereas the first molar region expansion was 0.57 cm. Similar mean values have been reported in other studies, 31,32 which shows that the amount of expansion is within the normal range and that such expansion does not need to be extreme to promote the changes obtained in the pharynx.…”

“…The surgically assisted rapid maxillary expansion (SARME) produces a widening at the nasal floor which reduces the nasal airflow resistance, improving the nasopharynx function and breathing patterns. The nasal cavity changes after SARME can be evaluated by cephalometric data [8][9] . Although this is widely used for the upper airway evaluation, there is still lack of cephalometric studies which specifically evaluate the upper airway after SARME.…”

Pharyngeal airway space cephalometric evaluation in transverse maxillary deficient patients after SARME

Aim:To evaluate prospectively the upper airway of 16 patients submitted to surgically assisted rapid maxillary expansion. Methods: Volumetric tomography acquisitions were done preoperatively (T1) and after six months postoperatively (T2), the slices were obtained from the hard palate to the third cervical vertebra (C3), the images were imported and reconstructed in the Dolphin software for 2D definition of the upper airway. A cephalometric radiograph was generated by the software, the cephalometric points were traced at T1 and T2 for all patients in a dark environment always by the same operator and the Arnett-Gunson FAB Surgery analysis was applied. Results: A statistically significant reduction in area (p=0.03) at the level of the nasopharynx was observed, while at the oropharynx and hypopharynx it showed no statistical difference between T1 and T2. Conclusions: The area in the nasopharynx level presented a statistically significant decrease, however, despite the area decrease at this point, the patients seem to do better, and thus, this area decrease may not be clinically significant.

“…Porém, há poucos relatos, e com metodologias divergentes, na avaliação de tais alterações com o tratamento cirúrgico de pacientes com deficiências transversais maxilares. Apesar da dificuldade em confrontar os resultados desta pesquisa devido à escassez de trabalhos com avaliações semelhantes, observa-se que tal assunto vem despertando o interesse atual dos pesquisadores (Mitsuda et al, 2010;Ramires et al, 2008;Baraldi et al, 2007). Assim, o presente trabalho demonstra a elaboração e os resultados de uma metolodologia inédita para a avaliação objetiva e subjetiva das alterações aéreas das cavidades nasais e para compará-las com as modificações das medidas ortodônticas maxilares.…”

“…Todas as medidas otorrinolaringológicas melhoraram com o uso de vasoconstritor nasal, fato também descrito por diversos autores, uma vez que o vasoconstritor reduz o edema da mucosas nasais, aumentando, assim, área seccional, volume e, como conseqüência, fluxo respirtório (Roithman et al, 1995b;Baraldi et al, 2007;Gomes et al, 2008;Mitsuda et al, 2010).…”

“…Esses resultados assemelham-se aos resultados de Wriedt et al (2001), Baraldi et al (2007) e Mitsuda et al (2010), os quais justificam que o volume livre aéreo é dependente de outros fatores otorrinolaringológicos, como as hipertrofias das conchas nasais inferiores ou desvios septais obstrutivos. Assim, ressalta-se a necessidade de avaliação criteriosa dos pacientes com pouca melhora nos padrões respiratórios após a EPCA, pois para esses casos, há grandes chances de existir necessidade de cirurgia otorrinolaringológica para a eliminação da obstrução nasal (Bicakci et al, 2005).…”

Effects of surgically assisted rapid maxillary expansion on nasal dimensions using acoustic rhinometry

Abstract: Surgically assisted rapid maxillary expansion increases the minor cross-sectional areas and volume of the nasal cavities. Acoustic rhinometry is an objective method for evaluating the geometry of the nasal cavity in patients with transverse maxillary deficiency.
