Os efeitos da expansão rápida da maxila sobre a permeabilidade nasal avaliados por rinomanometria e rinometria acústica

Abstract: O objetivo deste artigo foi analisar os achados da literatura acerca das repercussões da expansão rápida da maxila (ERM) sobre a permeabilidade nasal, pela rinomanometria, que avalia a resistência oferecida pela cavidade nasal à passagem do fluxo aéreo, e pela rinometria acústica, que mede as áreas seccionais e os volumes de diferentes segmentos da cavidade nasal. Estudos que utilizaram a rinomanometria evidenciaram que a ERM determina uma diminuição significativa da resistência nasal, assim como o aumento da … Show more

“…What is restricted to rhinometry is the need to extend the articulatory gesture sound that initiate the syllable, in this case the plosives, which leads to a somewhat artificial production that may not represent the operation functioning of the velopharyngeal mechanism in normal conditions. As for other possible limitations, widely discussed in other publications of the Laboratory of Physiology of the HRAC/USP (6,22,30) , all were considered, in the context of a project that aims to contribute to the analysis of the feasibility of using a technique as a complementary method for assessing velopharyngeal function.…”

“…A literatura cita a Rinomanometria Computadorizada e a Rinometria acústica, como sendo métodos mais específicos e objetivos para a avaliação desta função nasal 24 , porém há uma dependência de equipamentos caros, o que justifica sua não utilização de rotina 23 . Alguns autores ainda relatam que as desordens das vias aéreas superiores podem resultar em desajustes na dinâmica respiratória e há também um aumento da resistência nasal, pois os músculos acessórios da inspiração passam a ser solicitados, o que leva a um movimento inspiratório proeminente do tórax superior 25 .…”

“…According to Vidotti and Trindade, this effect is of particular importance because nasal obstruction can lead to atresia of the maxillary arch and maxillary atresia can determine a decrease in the width of the nasal cavity, which theoretically compromises nasal permeability (the passage of air through the nasal cavity), leading to a mouth-breathing pattern 19. A number of studies have reported an improvement in nasal breathing stemming from the gain in nasal cavity volume and reduction in nasal aerial resistance following the oto-surgical treatment of maxillary atresia 14.…”
