OBJETIVO: avaliar os efeitos da associação entre a remoção de hábitos de sucção e a Terapia Miofuncional Orofacial na ampliação da aeração nasal. MÉTODOS: vinte crianças na faixa de etária de quatro anos a quatro anos e oito meses foram distribuídas em dois grupos denominados de: Grupo REM (submetido apenas à remoção de hábitos) e Grupo TMF (submetido à remoção de hábitos e posteriormente à Terapia Miofuncional Orofacial). O fluxo de ar expirado pelas narinas foi registrado por meio do espelho nasal milimetrado de Altmann e quantificado em papel milimetrado denominado de Bloco de Referência do Espelho de Altmann. Os exames foram realizados em três momentos (pré-tratamento, 60 e 180 dias após). Os resultados foram submetidos à análise estatística, utilizando-se Test t para duas amostras independentes e para dados pareados, considerando nível de significância valores p<0,05. RESULTADOS: pode-se observar que as médias obtidas da quantificação da aeração nasal após os tratamentos foram significativamente maiores no Grupo TMF que no Grupo REM (p< 0,0001). CONCLUSÃO: houve aumento da aeração nasal e conseqüentemente melhora da função respiratória nasal, utilizando a Terapia Miofuncional Orofacial após remoção de hábitos de sucção em crianças na faixa etária de quatro anos.
BackgroundCraniofacial growth pattern has been correlated with variations in size of the upper airway spaces. The objective of this study was to evaluate the nasopharyngeal, oropharyngeal, and hypopharyngeal airway spaces variations according to the craniofacial growth pattern, by comparing brachyfacial, mesofacial, and dolichofacial in Angle Class I individuals.MethodsTo measure the spaces, 45 lateral teleradiographs were used and divided into 3 groups per the craniofacial growth pattern, determined by the Tweed cephalometry angular measurements: FMA and Y-axis. To evaluate the airways, sleep apnea cephalometry was used, containing 28 points that compose 14 factors. Three groups were compared relative to each of the 14 sleep apnea cephalometry measurements. Adherence test to the normal curve was performed. For the non-normally distributed data—measurement of the inferior pharyngeal space—the Kruskal-Wallis test was used for comparison between the groups. For the remaining data, the distribution was normal and ANOVA test was used.ResultsStatistically significant difference was verified among the groups for the measurement of the median posterior-palatal space, with the difference being pointed out by the post hoc test between the brachyfacial and dolichofacial groups. For the other measurements, there was no statistically significant difference.ConclusionsIt could be concluded that there was difference in the median posterior-palatal space measurement, in the oropharynx region, which was reduced for individuals with a dolichofacial pattern.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
