Estudo cefalométrico de alterações induzidas por expansão lenta da maxila em adultos

Abstract: A expansão da maxila é um procedimento que objetiva o aumento do arco dental maxilar para correção de desvios oclusais. Amplamente empregada em crianças, há controvérsias sobre sua eficácia em adultos, quando o crescimento crânio-facial já atingiu sua maturidade óssea. OBJETIVO: O presente estudo tem como objetivo avaliar modificações cefalométricas decorrentes da expansão da maxila em pacientes adultos, observando as seguintes medidas lineares: largura facial, largura nasal, altura nasal, largura maxilar, lar… Show more

“…The literature contains many papers describing relief of nasal obstruction after opening of the midpalatal suture by maxillary expansion in patients with maxillary atresia. 1 , 2 , 15 , 16 , 17 , 18 , 19 , 20 Relief of nasal obstruction occurs in cases where there was narrowing of the antero-posterior portion of the nasal cavity; during the maxillary expansion procedure this region is widened transversally. Such widening increases the airway space in the nasal cavity, resulting in improved nasal patency.…”

“…16 Nasal airflow and pressure have been investigated before and after RME, suggesting that maxillary expansion increases the nasal volume and reduces the NAR. 2,[4][5][6]18,24,[27][28][29] There remains some controversy in the literature about the relation between maxillary expansion and the nasal respiratory pattern. Warren et al have stated that the increased nasal flow resulting from a wider intranasal space produced by RME is not enough to change mouth breathing into nose breathing; an increased NAR may be associated -according to many authors -to turbinate hypertrophy, nasal polyps, adenoid hypertrophy and a deviated nasal septum, over which RME would have little effect.…”
