Aeração nasal e força muscular respiratória em crianças respiradoras orais

“…In addition, it was found, in the present study and on a study of 2007 13 , that many of the children weaned before four months of life. The correct breathing pattern may be impaired by weaning before six months of life, because it compromises the proper oral motor development and the lack of physiological sucking the breast allows the installation of malocclusion, motor-oral amendment and mouth breathing 4,14 .…”

“…Studies show that snoring and drooling relationship with mouth breathing can cause respiratory and sleep problems, caused by constant mouth opening, because the space of rinopharynx (throat region) is reduced due to nasal obstruction or allergic state 4,17 . In this study, despite snoring and drooling data have been approximated, but no difference between the two groups the mouth breathers had a higher frequency of these aspects also been observed in previus studies 8,13,16,18 .…”

“…Thus, the child makes less effort to breathe, aggravating the whole mechanical ventilation with the commitment of the lungs, abnormal respiratory rate, subject to the expansion and contraction of the lungs and alveolar ventilation. Thus, the diaphragm action will be reduced, as compromise their length-tension relationship, incapacitating him to produce adequate peak tension, leading to relaxation and requiring less respiratory muscle strength, which develops weakness with retraction muscular 3,4 .…”

“…Breathing is one of the vital functions of living beings developed at the first moment of life, soon after birth, in which the nasal breathing is considered the normal way to do it [1][2][3] . For the occurrence of nasal breathing, there needs to be anatomical and functional integrity of the upper airways, especially in the nasal region and / or pharyngeal 4,5 .…”

“…If the person has nasal breathing, it favors the good performance of the chewing, swallowing and speech functions, the adequacy of the mandibular, tongue, lips and facial expression posture, which, by acting with integrity and being interrelated provide a correct muscle action by stimulating the appropriate facial growth and bone development 1,13 . The most frequent cause of obstruction of the upper airways are due to organic changes such as nasal polyps, adenoid hypertrophic and / or tonsils, more frequent; allergic rhinitis, deviated septum, sinusitis and nasal turbinate hypertrophy 6,12,14 Regarding to the adenoids and the tonsils they are present in all children since birth and tend to increase in size from to 2 to 6 years old, period in which the hyperplasia of all lymphoid tissues occur.…”
