RESUMEN
ABSTRACT INTRODUCTION: Mouth breathing leads to negative consequences on quality of life, especially in school-age children. OBJECTIVE: To determine whether the breathing pattern influences children's learning process. METHODS: This systematic review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) instructions, with no restrictions regarding the year of publication and language, created based on the clinical question formulation according to the Problem/Patient/Population, Intervention/Indicator, Comparison, Outcome (PICO) strategy: "Is the mouth-breathing child more likely to have learning disabilities when compared to nasal breathers?" in the SciELO, PubMed, LILACS, and Scopus electronic databases. Google Scholar was used to search the gray literature. The keywords "learning," "mouth breathing," and their equivalent terms in Portuguese were used in an integrated manner. The studies included in the review were observational, conducted with schoolchildren aged 7-11 years. Afterwards, the studies were evaluated regarding their methodological quality. The research was performed by two eligible reviewers. RESULTS: A total of 357 records were obtained, of which 43 records were duplicate. After applying the eligibility criteria, ten articles were included in the research scope. Half of the studies used a control group and otorhinolaryngological assessment, whereas a minority used validated (20%) and sample calculation protocols (10%). The evaluation procedures were varied. Overall, 80% of the articles showed a higher incidence of learning disabilities among mouth breathers. CONCLUSION: This systematic review has shown that mouth breathers are more likely to have learning difficulties than nasal breathers.
Resumo Introdução: A respiração oral traz consequências negativas para a qualidade de vida das pessoas, principalmente para escolares. Objetivo: Verificar se o modo respiratório influencia no processo de aprendizagem infantil. Método: Esta revisão sistemática foi realizada seguindo as instruções PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), sem restrição quanto ao ano de publicação e idioma, elaborada a partir da formulação de questão clínica elaborada pela estratégia P.I.C.O.: ''A criança respiradora oral tem mais chances de apresentar dificuldades de aprendizagem quando comparada à respiradora nasal?'', nas bases de dados eletrônicas SciELO, PubMed, LILACS e Scopus. Foi utilizado o Google Scholar para pesquisa da literatura cinza. As palavras-chave ''aprendizagem'', ''respiração bucal'', ''learning'' e ''mouth breathing'' foram utilizadas de forma integrada. Os estudos incluídos foram observacionais, realizados com escolares entre sete e onze anos. Em seguida, os estudos foram avaliados quanto à sua qualidade metodológica.

BACKGROUND: Mouth breathing can exert an influence on quality of life and should be evaluated within a multidimensional context. However, there is no specific questionnaire to measure the impact of mouth breathing on quality of life. OBJECTIVE: To develop and validate a questionnaire for measuring the impact of mouth breathing on quality of life among children and adolescents. METHODS: Thirty-six items were evaluated by six health care professionals, one parent and one child with mouth breathing. After a qualitative evaluation, a modified set of 32 items was developed. The modified Mouth Breather Quality of Life (MBQoL) questionnaire was submitted to a pretest with a sample of 30 children and adolescents diagnosed with mouth breathing to evaluate comprehension, the order of the items, and the form of administration. The MBQoL questionnaire was then administered to 60 children and adolescents (30 mouth breathers and 30 nose breathers) for the evaluation of construct validity, internal consistency, and reproducibility. All the participants answered the questionnaire, and 50% of each group answered the questionnaire a second time after a 1-week interval (test-retest). RESULTS: Higher MBQoL scores (which indicated poorer quality of life) were significantly associated with mouth breathing. The Cronbach α coefficient for the items of the questionnaire was 0.88, and the Spearman correlation coefficient for test-retest reliability demonstrated that the questionnaire was reproducible (r = 0.993; p < 0.01). CONCLUSION: Through this validation study, the MBQoL questionnaire demonstrated a good performance in the evaluation of the quality of life of children and adolescents with mouth breathing and may be a useful tool in clinical studies as well as public health programs. However, further studies are needed to establish its applicability in other populations with respiration disorders.

OBJECTIVE: To assess short-term tomographic changes in the upper airway dimensions and quality of life of mouth breathers after rapid maxillary expansion (RME). METHODS: A total of 25 mouth breathers with maxillary atresia and a mean age of 10.5 years old were assessed by means of cone-beam computed tomography (CBCT) and a standardized quality of life questionnaire answered by patients' parents/legal guardians before and immediately after rapid maxillary expansion. RESULTS: Rapid maxillary expansion resulted in similar and significant expansion in the width of anterior (2.8 mm, p < 0.001) and posterior nasal floor (2.8 mm, p < 0.001). Although nasopharynx and nasal cavities airway volumes significantly increased (+1646.1 mm3, p < 0.001), oropharynx volume increase was not statistically significant (+1450.6 mm3, p = 0.066). The results of the quality of life questionnaire indicated that soon after rapid maxillary expansion, patients' respiratory symptoms significantly decreased in relation to their initial respiratory conditions. CONCLUSIONS: It is suggested that RME produces significant dimensional increase in the nasal cavity and nasopharynx. Additionally, it also positively impacts the quality of life of mouth-breathing patients with maxillary atresia.

INTRODUCTION: The main cause of mouth breathing and sleep-disordered breathing (SDB) in childhood is associated with upper airway narrowing to varying degrees. OBJECTIVE: The aim of this study was to assess the prevalence of morphological and functional craniofacial changes and the main clinical symptoms of SDB in healthy children. METHODS: A cross-sectional observational study was conducted. A sample comprising 687 healthy schoolchildren, aged 7-12 years old and attending public schools, was assessed by medical history, clinical medical and dental examination, and respiratory tests. The self-perceived quality of life of mouth breathing children was obtained by a validated questionnaire. RESULTS: Out of the total sample, 520 children were nose breathers (NB) while 167 (24.3%) were mouth breathers (MB); 32.5% had severe hypertrophy of the palatine tonsils, 18% had a Mallampati score of III or IV, 26.1% had excessive overjet and 17.7% had anterior open bite malocclusion. Among the MB, 53.9% had atresic palate, 35.9% had lip incompetence, 33.5% reported sleepiness during the day, 32.2% often sneezed, 32.2% had a stuffy nose, 19.6% snored, and 9.4% reported having the feeling to stop breathing while asleep. However, the self-perception of their quality of life was considered good. CONCLUSION: High prevalence of facial changes as well as signs and symptoms of mouth breathing were found among health children, requiring early diagnosis and treatment to reduce the risk of SDB.

OBJECTIVE: To investigate the respiratory and postural adaptations associated with mouth and nasal breathing and to evaluate the associations of such adaptations in mouth breathers' self-perceived quality of life. METHOD: Cross-sectional study with mouth breathers (initial n=116 and final n=48) and nasal breathers (initial n=131 and final n=24) from elementary school, aged between 7 and 14 years. Chest expansion, using cirtometry, the breathing pattern and the use of accessory muscles, by means of clinical evaluations and photogrammetry, and flexibility tests were evaluated in both groups. Subsequently, the mouth breathers were asked to complete the quality of life questionnaire. Statistical tests: Chi-square, odds ratio, Mann-Whitney, and binomial tests were first applied followed by logistic regressions. RESULTS: Thoracic breathing (p=0.04), using of accessory muscles (p=0.03) and reductions in flexibility (p=0.001) increased the chances of an individual being a mouth breather when compared to nasal breathers. Subsequently, using of accessory muscles decreased the chances of snoring among mouth breathers (p=0.03); the presence of shoulder asymmetry reduced the chances of experiencing quiet sleep (p=0.05) and increased the chances of coughing or being tired when playing or running (p=0.008). Finally, forward head position reduced the chances of waking up at night (p=0.04) and experiencing shortness of breath (p=0.05). CONCLUSIONS: Respiratory and postural adaptations increased the chances of individuals persisting with mouth breathing. Additionally, these adaptations could be associated with mouth breathers' self-perceived quality of life.

OBJETIVO: avaliar, por meio de tomografias, as mudanças em curto prazo nas vias aéreas superiores e na qualidade de vida em pacientes respiradores bucais, após expansão rápida da maxila (ERM). MÉTODOS: foram avaliados 25 pacientes respiradores bucais com atresia maxilar, com idade média de 10,5 anos, por meio de tomografia computadorizada de feixe cônico (TCFC) e questionário padronizado de qualidade de vida submetido aos pais/responsáveis, antes e imediatamente após a ERM. RESULTADOS: a ERM promoveu uma expansão, de forma semelhante e significativa, tanto na largura do soalho nasal anterior (2,8mm, p < 0,001) quanto na largura do soalho nasal posterior (2,8mm, p < 0,001). No volume aéreo da nasofaringe e fossas nasais, houve aumento significativo (+1646,1mm3 p < 0,001); entretanto, no volume aéreo da orofaringe, houve aumento não significativo (+1450,6 mm3 p = 0,066). Os resultados do questionário de qualidade de vida indicaram melhora significativa na qualidade de vida dos pacientes após a ERM, em comparação ao questionário inicial. CONCLUSÕES: a ERM promoveu aumento dimensional significativo nas fossas nasais e na nasofaringe, bem como melhorou significativamente a qualidade de vida dos pacientes. .

INTRODUÇÃO: a principal causa da respiração bucal e dos distúrbios respiratórios do sono (DRS) está associada ao estreitamento das vias aéreas superiores, em diferentes graus. OBJETIVO: avaliar a prevalência de alterações morfológicas e funcionais da face e os principais sintomas clínicos de DRS em crianças saudáveis. MÉTODOS: estudo transversal, observacional, com amostra de 687 escolares saudáveis, provenientes de escolas públicas, com idades entre 7 e 12 anos. Foram avaliados pela história clínica, exame clínico médico e odontológico e testes respiratórios. A autopercepção da qualidade de vida dos escolares com respiração bucal foi obtida por meio de um questionário validado. RESULTADOS: na amostra total, 520 crianças eram respiradoras nasais (RN) e 167 (24,3%) eram respiradoras bucais (RB); 32,5% tinham hipertrofia das amígdalas palatinas, 18% tinham índice Mallampati obstrutivo (III e IV); 26,1% tinham overjet exagerado e 17,7%, mordida aberta anterior. Entre os RB, 53,9% tinham palato atrésico; 35,9% com ausência de selamento labial; 33,5% relataram sonolência diurna; 32,2%, espirros frequentes; 32,2%, nariz entupido; 19,6% roncavam e 9,4% relataram ter a sensação de parar de respirar durante o sono. Entretanto, a autopercepção da qualidade de vida desses escolares foi considerada boa. CONCLUSÃO: foi encontrada alta prevalência de alterações faciais, de sinais e de sintomas clínicos de respiração bucal nos escolares saudáveis examinados, necessitando diagnóstico e tratamento para reduzir o risco de DRS. .
