Impact of rapid maxillary expansion on mouth-breathing children and adolescents : a systematic review
Rapid maxillary expansion (RME) is an orthodontic procedure used to correct transverse maxillary deficiency. Due to the anatomical relationship between the palate and the nasal cavity, RME promotes an increase in nasal dimensions, which should hypothetic
Correlation between acoustic rhinometry, computed rhinomanometry and cone beam computed tomography in mouth breathers with transverse maxillary deficiency
Orientadores: José Dirceu Ribeiro, Eulália SakanoDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências MédicasResumo: Introdução: Vários exames podem ser realizados para complementar informações clínicas e diagnósticas em respiradores bucais com deficiência transversal maxilar, entretanto a correlação entre estes exames ainda é incerta. Objetivo: Avaliar a correlação entre a função respiratória nasal e as medidas tridimensionais dos ossos nasais e maxilares em respiradores bucais com atresia maxilar. Método: Um estudo de corte transversal foi realizado com trinta respiradores bucais (7 a 13 anos) portadores de deficiência transversal maxilar e mordida cruzada posterior. Foram realizados os exames: (i) rinometria acústica: volumes nasais (0 a 5cm e 2 a 5cm) e áreas transversais mínimas (MCA1 e MCA2) da cavidade nasal; (ii) rinomanometria computadorizada: fluxo nasal e resistência média inspiratória e expiratória; (iii) tomografia computadorizada cone beam: cortes coronais na cabeça da concha nasal inferior (larguras 1 e 2), concha nasal média (larguras 3 e 4) e maxila (largura 5). Os exames de rinometria acústica e rinomanometria foram avaliados antes e após a administração de vasoconstritor. Os resultados foram comparados pela Correlação de Spearman e Teste de Mann-Whitney (?=0,05). Resultados: Foram encontradas correlações positivas entre: (i) fluxo antes da administração do vasoconstritor e largura 4 (Rho=0,380) e largura 5 (Rho=0,371); (ii) largura 2 e MCA1 antes da administração de vasoconstritor (Rho=0,380); (iii) fluxo antes da administração de vasoconstritor e volumes nasais de 0 a 5cm (Rho=0,421), 2 a 5cm (Rho=0,393) e MCA1 (Rho=0,375); (iv) largura 4 e volume nasal de 0 a 5cm antes da administração do vasoconstritor (Rho= 0,376), volume nasal 2 a 5cm após o uso de vasoconstritor (Rho= 0,376), MCA1 antes da administração de vasoconstritor (Rho= 0,410) e MCA1 após o uso do vasoconstritor (Rho= 0,426); (v) largura 5 e largura 1 (Rho=0,542), largura 2 (Rho=0,411) e largura 4 (Rho=0,429). Foram encontradas correlações negativas entre: (i) largura 4 e resistência inspiratória média (Rho=-0,385); resistência inspiratória média antes da administração de vasoconstritor e volume de 0 a 5cm (Rho=-0,382) e resistência expiratória média antes da administração de vasoconstritor e MCA1 (Rho=-0,362). Conclusão: Crianças e adolescentes respiradores bucais com atresia maxilar apresentam correlações entre as larguras nasal e maxilar e a função respiratória nasalAbstract: Introduction: To supplement clinical information and diagnosis in mouth breathers with transverse maxillary deficiency, several exams can be performed; however, the correlation among these exams remains unclear. Objective: To evaluate the correlation between nasal respiratory function and three-dimensional measurements of nasal and maxillary bones in mouth breathers with transverse maxillary deficiency. Methods: A cross-sectional study was conducted in 30 mouth breathers with transverse maxillary deficiency (7-13 y.o.) with posterior crossbite. The examinations assessed: (i) acoustic rhinometry: nasal volumes (0-5 cm and 2-5 cm) and minimum cross-sectional areas 1 and 2 of nasal cavity; (ii) computed rinomanometry: nasal flow and average inspiratory and expiratory resistance; (iii) cone-beam computed tomography: coronal section on the head of inferior turbinate (Widths 1 and 2), middle turbinate (Widths 3 and 4) and maxilla levels (Width 5). Acoustic rhinometry and computed rhinomanometry were evaluated before and after administration of vasoconstrictor. Results were compared by Spearman's correlation and Mann-Whitney tests (?= 0.05). Results: Positive correlations were found between: (i) flow evaluated before administration of vasoconstrictor and Width 4 (Rho= 0.380) and Width 5 (Rho= 0.371); (ii) Width 2 and minimum cross-sectional areas 1 evaluated before administration of vasoconstrictor (Rho= 0.380); (iii) flow evaluated before administration of vasoconstrictor and nasal volumes of 0-5 cm (Rho= 0.421), 2-5 cm (Rho= 0.393) and minimum cross-sectional areas 1 (Rho= 0.375); (iv) width 4 and nasal volumes of 0-5cm evaluated before administration of vasoconstrictor (Rho= 0.376), 2-5cm evaluated before administration of vasoconstrictor (Rho= 0.376), minimum cross-sectional areas 1 evaluated before administration of vasoconstrictor (Rho= 0.410) and minimum cross-sectional areas 1 after administration of vasoconstrictor (Rho= 0.426); (v) width 5 and width 1 (Rho= 0.542), width 2 (Rho= 0.411), and width 4 (Rho= 0.429). Negative correlations were found between: (i) width 4 and average inspiratory resistance (Rho= -0.385); (ii) average inspiratory resistance evaluated before administration of vasoconstrictor and volume of 0-5cm (Rho= -0.382), and average expiratory resistance evaluated before administration of vasoconstrictor and minimum cross-sectional areas 1 (Rho= -0.362).
