Alterações posturais e função pulmonar de crianças respiradoras bucais

Abstract

Mout h-breathing children have changes in their stomatognathic system, which result in head projection, stress increase in the scapular belt muscles and postural adaptations. Although thoracic shape and posture can influence ventilatory dynamics, we didn't find studies addressing pulmonary function of mouth-breathing children.Aims: this study aimed at analyzing the posture of mouth-breathing children, and studying the existence of correlations between posture and pulmonary volumes.Material and Methods: prospective, observational and cross-sectional study, where the posture and pulmonary function of 17 mouth-breathing children and of 17 nasal-breathing children were evaluated by means of photogrammetry and forced spirometry.Results: when compared to nasal-breathing, mouth-breathing subjects presented an increment in head projection and cervical lordosis, forwarded gravity center and reduced pulmonary volumes. There was an association between head projection and forced vital capacity, and between postural alterations and age.Conclusion: mouth-breathing children have postural alterations which increases with age and also reduced spirometry values. The vital capacity reduction correlates negatively with head projection. Braz J Otorhinolaryngol. 2010;76(6):683-6. BJORL ORIGINAL ARTICLE

Expansão rápida da maxila em paciente adolescente: Relato de caso / Rapid maxillary expansion in adolescent patient: Case report

“…Portanto, a manutenção constante da boca aberta altera todo o equilíbrio neuromuscular da face 7 . As alterações posturais dos respiradores orais, aumentam em função da idade 45 . Já os hábitos relacionados aos músculos mastigatórios (onicofagia, morder lábios e/ou bochechas, bruxismo, dentre outros) resultam em hiperfunção dos músculos masseteres, temporais e pterigoideos mediais e laterais, podendo resultar na diminuição da coordenação muscular, além de possíveis sensações de dores 10 .…”

Evaluación interdisciplinaria estomatognática y postural en un sujeto pediátrico respirador oral: Reporte de caso

“…Cuccia et al, (33) concluyeron que en la RO se crea un imbalance muscular y una mayor extensión de la cabeza en relación con la columna cervical. Otros autores plantean (34) que en estos niños aumenta la tensión en los músculos de la cabeza y hombros, cambiando su posición en las direcciones anteroposterior o lateral. El participante presentó cabeza con tendencia a la inclinación lateral derecha, y en vista lateral, cabeza y abdomen en posición adelantada, esto coincide con el estudio realizado por Cuccia et al (33) .…”

Nasal patency and craniocervical posture in scholar children

“…Such postural deviation has been frequently associated with mouth breathing mode, without considering its etiology, whether obstructive or functional. Forward head posture in mouth breathing occurs due to oropharynx rectification to facilitate the air passage in case of nasal obstruction 5,6 . Nevertheless, the association between forward head posture and mouth breathing does not represent a consensus.…”

“…The postural compensation for airflow maintenance may target not only the lip and tongue posture, but also the whole body, mainly in morphologically prone patterns 3 . The postural changes observed in children may determine a worsening in respiratory dysfunction, in which a feedback system may be installed, causing a progressive respiratory and musculoskeletal impairment 5 . The head posture deviation, especially the forward head posture, may cause a compensating mechanism for the normal respiratory function maintenance 4,6,7 .…”

“…The head posture deviation, especially the forward head posture, may cause a compensating mechanism for the normal respiratory function maintenance 4,6,7 . Such alterations, if not corrected, may aggravate respiratory problems or even reflect negatively on adult life 3,5,8 . Therefore, the previous detection of postural misalignment and its relation with nasal obstruction may influence not only problem solving, but also the prevention of systemic consequences.…”
