The mouth breathing syndrome is characterized by a set of signs and symptoms, which may be present in subjects who replace an adequate and efficient nasal breathing mode by the mouth or mist breathing mode, for a period equal or superior of six months. The mouth or mist breathing mode may be associated to changes in the ventilatory function and mechanics. This review has the objective of investigating more deeply the consequences of the mouth breathing in the lung function and respiratory muscles, emphasizing the development of such changes since childhood to adult age. Eighteen articles were selected through data basis PubMed and Web of Science and they were grouped in the text, comprehending the follow topics:1) Implications of mouth breathing on the lung function and 2)Implications of mouth breathing on the respiratory muscles. From the information derivate of the analyzed articles, it may realized that few studies reject or did not find some relation between pulmonary changes and mouth breathing. It was suggested that the muscular unbalance produced by these changes may contribute for the mechanic disadvantage of the diaphragm muscle and increase of accessory inspiratory muscles work. Nevertheless, studies with more selective method, including objective and reproducible evaluation of the respiratory muscles are still need. Keywords: Mouth Breathing; Respiratory System; Pulmonary Ventilation; Respiratory Muscles RESUMO A Síndrome do Respirador Oral é caracterizada por um conjunto de sinais e sintomas que podem estar presentes em indivíduos que substituem o modo adequado e eficiente da respiração nasal pelo modo respiratório oral ou misto, por um período igual ou superior a seis meses. O modo respiratório oral ou misto pode estar associado a mudanças na função e mecânica ventilatória. Esta revisão tem como objetivo investigar mais profundamente as consequências da respiração oral na função pulmonar e músculos respiratórios, ressaltando o desenvolvimento de tais alterações desde a infância até a idade adulta. Foram selecionados 18 artigos por meio das bases de dados Pubmed e Web of Science e foram agrupados no texto, compreendendo os seguintes tópicos: 1) Implicações da respiração oral sobre a função pulmonar e 2) Implicações da respiração oral sobre os músculos respiratórios. A partir das informações oriundas dos resultados dos artigos analisados, percebe-se que poucos estudos refutam ou não encontram alguma relação entre as alterações pulmonares e a respiração oral. Sugere-se que, o desequilíbrio muscular produzido por estas alterações pode contribuir para a desvantagem mecânica do músculo diafragma e aumento do trabalho dos músculos acessórios da inspiração. Entretanto, são necessários estudos com métodos mais criteriosos, incluindo avaliações objetivas e reprodutíveis dos músculos respiratórios.

“…As consequence, there may be a disadvantage in diaphragm muscle action and lack of synergism with abdominal muscles (36). It is important to underscore that these imbalances cause postural adaptations that may become progressive (4).…”

“…Moreover, postural changes occur continuously during the entire ontogenesis, with critical periods at school age and puberty (32,37). If perpetuated, mouth breathing in adulthood can cause a decrease in diaphragmatic amplitude and electrical activity of accessory muscles owing to muscle shortening (36).…”

Introduction: Mouth breathing can lead to changes in body posture and pulmonary function. However, the consequences are still inconclusive and a number of studies are controversial. Objective: Evaluate and correlate spirometric parameters and postural measures in mouth breathing children, and compare them to nose breathers. Methods: two groups of 6 to 12 year-old children were evaluated: mouth breathers (MB, n = 55) and nose breathers (NB, n = 45). Spirometry and body posture analysis using photogrammetry (SAPo 0.68® v) were carried out. The following spirometric measures were evaluated: peak expiratory low (PEF), forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio (%) and forced expiratory low between 25% and 75% of FVC (FEF 25-75%). Biophotogrammetric measures analyzed were: horizontal alignment of acromions (HAA) and anterior superior iliac spine (HAASIS), Charpy angle, horizontal alignment of the head (HAH), cervical lordosis (CL), thoracic kyphosis (TK), lumbar lordosis (LL), cervical distance (CD) and lumbar distance (LD). Results: There were no intergroup differences in spirometric and postural variables. Positive and moderate correlations were found between CL and CD measures with PEF, FEV1, FVC and FEF 25-75%, while weak correlations were observed between lumbar lordosis and PEF, FEV1 and FVC. Conclusion: The breathing mode had no in luence on postural and respiratory measures. However, greater forward head posture, with smaller cervical lordosis, was related to higher lung volumes and lows in both groups.

This review is a comprehensive description of all muscles that assist lung inflation or deflation in any way. The developmental origin, anatomical orientation, mechanical action, innervation, and pattern of activation are described for each respiratory muscle fulfilling this broad definition. In addition, the circumstances in which each muscle is called upon to assist ventilation are discussed. The number of “respiratory” muscles is large, and the coordination of respiratory muscles with “nonrespiratory” muscles and in nonrespiratory activities is complex—commensurate with the diversity of activities that humans pursue, including sleep (8.27). The capacity for speech and adoption of the bipedal posture in human evolution has resulted in patterns of respiratory muscle activation that differ significantly from most other animals. A disproportionate number of respiratory muscles affect the nose, mouth, pharynx, and larynx, reflecting the vital importance of coordinated muscle activity to control upper airway patency during both wakefulness and sleep. The upright posture has freed the hands from locomotor functions, but the evolutionary history and ontogeny of forelimb muscles pervades the patterns of activation and the forces generated by these muscles during breathing. The distinction between respiratory and nonrespiratory muscles is artificial, as many “nonrespiratory” muscles can augment breathing under conditions of high ventilator demand. Understanding the ontogeny, innervation, activation patterns, and functions of respiratory muscles is clinically useful, particularly in sleep medicine. Detailed explorations of how the nervous system controls the multiple muscles required for successful completion of respiratory behaviors will continue to be a fruitful area of investigation. © 2019 American Physiological Society.
