A postura corporal e as funções estomatognáticas em crianças respiradoras orais: uma revisão de literatura

Abstract

Children's body posture has been studied more and more by physical therapy, as well as mouth breather children have been studied by speech-language-hearing therapy. This study tries to check, through scientific literature, the relationship between stomatognathic functions and body posture in mouth breather children. This is a review of literature on body posture and the stomatognathic system in obstructive and functional mouth breathers. We searched, in electronic data basis such as MEDLINE, SCIELO and LILACS, and Google Scientific, articles related to these topics, published in the last 10. The selected articles were organized according to authors, title, source, age, and publishing year. When related to the type, the studies were considered: literature review articles; descriptive data analysis; field research. After selecting the texts, we identified four studies that relate posture, stomatognathic system and mouth breathing; two studies that relate stomatognathic system and posture; 13 studies relating to the stomatognathic system and mouth breathing. We may perceive that there is a lack of studies correlating body posture and stomatognathic system in oral breathers. The lack is even higher when we compare obstructive oral breathers and vicious oral breathers relating the body posture to the stomatognathic system.

Benefits of physical therapy in the quality of life of mouth breathing children: Literature review

“…It is an adaptive function in which the SS can promote structural changes that allow its installation and functionality, impairing the balance between masticatory functions, swallowing, breathing and phonation, a necessary condition for the proper development and normal growth of this system. 12 Nasal breathing is essential because it stimulates the sensors of the nasal mucosa, by filtering, heating and humidifying the air before reaching the lung and fulfilling its function of hematosis. The flow and reflux of air through the nostrils produce pressure that expands the airways and aerates the pneumatic paranasal cavities.…”

“…Therefore, changes in any of its parts lead to a general imbalance of the system. 12 The accessory muscles of aspiration include the scalene muscles, which lift the first two ribs and the sternocleidomastoid (SCM), which elevates the sternum. Also related to the respiratory act are the external intercostal muscles, which connect adjacent ribs and tilt downward and forward.…”

“…5 The nose, in addition to being a passive conductor through which air is drawn from the atmosphere, is a highly specialized organ capable of performing three important respiratory functions: humidification, heating of aspired air and protection of the upper airways. 12 As air passes through the nose, three distinct respiratory functions are performed by the nasal cavities: (1) the air is heated by the extensive surfaces of the shells and septa; (2) the air is almost completely humidified; and (3) the air is partially filtered. These functions are collectively termed the air conditioning of the upper airways.…”

Temporomandibular dysfunction and functional mandibular limitation

“…Therefore, changes in any of its parts lead to a global imbalance of the system. TMJ is able to perform complex movements associated with the action of chewing muscles, allowing the performance of neurovegetative functions, including speech (3,4) . Temporomandibular dysfunction (TMD) is a widely used term that involves several clinical problems and a wide range of changes in the masticatory muscles, TMJ and associated bone structures, which has so many problems with complex symptoms and rarely presented separately.…”

Speech production assessment of mouth breathing children with hypertrophy of palatines and/or pharyngeal tonsils

“…The exchange of nasal respiratory mode for oral one is quite common in the first years of life due to interfering factors 4 , such as organic changes: obstruction of the upper airways (rinitis 5 , hypertrophic palatine and/ or pharyngeal tonsils, deviation of septum, among others), or even non-organic changes, due to deleterious habits 2,6 .…”
