ABSTRACT

ABSTRACT Purpose: to analyze the correlation between the values of nasal aeration and geometry of the nasal cavities, before and after nasal cleansing in children with mouth breathing. Methods: 20 children aged 4 to 12 years old were chosen. The questionnaire Identification Index of Signs and Symptoms of Oral breathing was applied and nasal patency was assessed by nasal aeration, through the Altmann graded mirror, and the nasal geometry measured by acoustic rhinometry. After nasal cleansing and massage, the same aeration measurements and nasal geometry procedures were performed. Group normality was analyzed using the Shapiro-Wilk test considering the hypothesis of normal distribution whenever p>0.05. The Spearman's test was applied to analyze the correlation between variables (p<0.05). Results: there was a strong and significant correlation between nasal aeration and the corresponding cross-sectional area of the front of the inferior turbinate (CSA2) in the left cavity before cleansing. There were no correlations between the nasal aeration and other rhinometric variables. Conclusion: there was a correlation between nasal aeration values and the anterior portion of the turbinates, before the massage and nasal cleansing technique, in mouth breathing children. There were no significant differences when the nasal aeration was correlated with other rhinometric variables.

ABSTRACT

RESUMO A avaliação e quantificação das possíveis alterações da cavidade nasal são necessárias para o auxílio diagnóstico e tratamento de crianças que respiram predominantemente pela boca. O modo respiratório oral pode desencadear distúrbios da fala, deformidades da face, mau posicionamento dos dentes, postura corporal inadequada e alterações no sistema respiratório. Objetivo analisar as mudanças ocorridas na geometria das cavidades nasais, antes e depois da limpeza nasal por meio da aeração nasal e da rinometria acústica em crianças com respiração oral. Método Foram selecionadas 20 crianças com idade entre quatro e 12 anos. A coleta foi realizada no Laboratório Multifuncional do Departamento de Fonoaudiologia da Universidade Federal de Pernambuco. Foi aplicado o Índice de Identificação dos Sinais e Sintomas da Respiração Oral; marcação da aeração nasal por meio do espelho milimetrado de Altmann e o exame da geometria nasal por Rinometria Acústica. Depois da limpeza e massagem nasal com o soro fisiológico, foram realizados os mesmos procedimentos. Resultados Observaram-se mudanças significantes nas áreas relativas ao fluxo aéreo nasal em ambos os lados, após limpeza e massagem nasais. Quanto à geometria nasal, aferida por meio da rinometria acústica, o efeito da limpeza e massagem nasal mostrou-se discreto, quando feita a comparação entre as narinas. Conclusão As medidas de aeração nasal mostraram sensibilidade à técnica de limpeza e massagem e as medidas da geometria nasal confirmaram seu efeito sobre a fisiologia respiratória.


ABSTRACT The evaluation and quantification of possible changes in the nasal cavity can assist in the diagnostics and treatment in children who breathe predominantly through the mouth. The oral breathing mode can initiate speech disorders, facial deformities, poor positioning of the teeth, improper body posture, and changes in the respiratory system. Purpose To analyze the changes occurred in the nasal cavity geometry, before and after nasal cleansing, through nasal aeration and acoustic rhinometry in children with oral breathing. Methods Twenty children aged four to 12 years were included in the study. The gathering of participants was conducted at the Multifunctional Laboratory of the Speech Pathology Department of the Federal University of Pernambuco - UFPE. The following procedures were conducted: Identification Index of Signs and Symptoms of Oral Breathing; marking of nasal expiratory airflow using the graded mirror of Altmann, and examination of the Nasal Geometry by Acoustic Rhinometry. The same procedures were performed after nasal massage and cleansing with saline solution. Results Significant change was observed in the areas with respect to the nasal airflow on both sides after nasal cleansing and massage. As for nasal geometry, measured by acoustic rhinometry, comparison between the nostrils showed that the effect of cleansing and massage was discrete. Conclusion Nasal aeration measures showed sensitivity to the cleansing and massage technique and measures of nasal geometry confirmed its effect on respiratory physiology.

ABSTRACT

Introduction The child who chronically breathes through the mouth may develop a weakness of the respiratory muscles. Researchers and clinical are seeking for methods of instrumental evaluation to gather complementary data to clinical evaluations. With this in mind, it is important to evaluate breathing muscles in the child with Mouth Breathing. Objective To develop a review to investigate studies that used evaluation methods of respiratory muscle strength in mouth breathers. Data Synthesis The authors were unanimous in relation to manovacuometry method as a way to evaluate respiratory pressures in Mouth Breathing children. Two of them performed with an analog manovacuometer and the other one, digital. The studies were not evaluated with regard to the method efficacy neither the used instruments. Conclusion There are few studies evaluating respiratory muscle strength in Mouth Breathing people through manovacuometry and the low methodological rigor of the analyzed studies hindered a reliable result to support or refuse the use of this technique...

ABSTRACT

Introduction: The III Brazilian Consensus on Rhinitis (2012) defines allergic rhinitis as a nasal mucosa inflammation, mediated by immunoglobulin E, after exposure to allergens. The classic signs and symptoms of allergic rhinitis are nasal obstruction, watery rhinorrhea, sneezing, and nasal itching, often reversible either spontaneously or with treatment, and mouth breathing (breathing predominantly through the mouth, regardless of the cause, due to a nasal breathing impairment) in some cases. Objective: To evaluate the literature on masticatory changes in children with mouth breathing due to allergic rhinitis. Methods: We conducted a search of the past 10 years, at Bireme and MEDLINE databases, for articles that covered masticatory changes in children with mouth breathing secondary to allergic rhinitis. Results: We found 1,986 articles, including 15 repeated in databases, but only two articles met the inclusion criteria fully. Discussion: We found few studies to answer the question raised in this review, and those studies have some methodological limitations. Most articles claimed no have statistically significant differences in masticatory changes in this population. Conclusion: A better controlled study (isolating diseases, exposure time), with a larger sample (sample calculation appropriate), would be necessary to examine such changes...

ABSTRACT

Introduction: Changes in the respiratory system of asthmatics are also due to the mechanical disadvantage caused by the increased airway resistance. Objective: The study aims to evaluate the respiratory muscle strength and nutritional status of asthmatic children. Method: This is a prospective descriptive and transversal study with 50 children aged 7 to 12 years, who were placed into 2 groups, asthmatic and non-asthmatic. Respiratory muscle strength was evaluated on the basis of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). The nutritional status was evaluated by measuring the anthropometric data, including height, weight, and body mass index (BMI). The findings were subjected to analysis of variance, chi-square, and Student's t test, and p-values<0.05 was considered statistically significant. Results: In our comparisons, we observed statistically significantly lower values for age, weight, and height in asthmatic patients: 8.52 ± 1.49 years, 30.62 ± 7.66 kg, and 129.85 ± 10.24 cm, respectively, vs. non-asthmatic children(9.79 ± 1.51 years, 39.92 ± 16.57 kg, and 139.04 ± 11.62 cm, respectively). There was no significant increase in MIP and MEP between the groups: MIP was -84.96 ± 27.52 cmH2O for the asthmatic group and -88.56 ± 26.50 cmH2O for the non-asthmatic group, and MEP was 64.48 ± 19.23 cmH2O for asthmatic children and +66.72 ± 16.56 cmH2O for non-asthmatics. Conclusion: There was no statistically significant difference between groups, but we observed that MIP and MEP were slightly higher in the non-asthmatic group than in the asthmatic group...

ABSTRACT

Introduction: The prevalence of asthma has grown considerably in recent decades, but some studies have shown stabilization of this trend. The masticatory process of asthmatic children may be altered due to asthma-related anatomo-functional changes. Objective: The study objective was to determine the clinical and electromyographic characteristics of the masticatory process in asthmatic children and compare the electrical activities of their masseter and anterior temporal muscles (at rest and during maximal voluntary contraction and mastication) with those of non-asthmatic children. Method: Case study. Asthmatic and non-asthmatic groups, each consisting of 30 children of both sexes between 6 and 10 years of age, were evaluated. Mastication was evaluated clinically and electromyographically in all subjects. RESULTS: The masticatory process did not differ significantly between asthmatic and non-asthmatic children. Conclusion: Although the masticatory process did not differ significantly between asthmatic and non-asthmatic children, the masticatory process of asthmatic children may be altered because of anatomical changes of Asthma...

ABSTRACT

OBJETIVO: identificar a presença de sinais de alterações na expiração de crianças asmáticas. MÉTODO: este estudo foi realizado com 30 crianças com idades entre 6 e 10 anos de ambos os sexos com diagnóstico clínico de asma confirmado pelo prontuário médico e 30 crianças não asmáticas também de ambos os sexos na mesma faixa etária. Foi avaliada a aeração nasal com o espelho milimetrado de Altmann, sendo mensurado o escape de ar nasal objetivando a verificação da saída uni ou bilateral do ar e a relação de simetria entre a narina direita e a esquerda. As imagens foram importadas para o computador por meio do scanner HP da série Scanjet 2400. A análise foi realizada no software Scion Image for Windows (Alpha 4.0.3.2). Para análise das variáveis quantitativas entre grupos foi aplicado o teste t-student e para a análise intragrupos foi aplicado o teste t-Student pareado.Todas as conclusões foram tomadas ao nível de significância de 5 por cento, sendo usados o Excel 2000 e o SPSS v8.0, para as análises. RESULTADOS: não foram encontradas diferenças estatisticamente significantes entre as crianças asmáticas e não-ásmáticas, acerca das mensurações quanto à área total e quanto às áreas das narinas direita e esquerda. CONCLUSÃO: não foi identificada a presença de sinais de alterações na expiração de crianças asmáticas, desta forma, faz-se necessário um estudo mais específico das funções nasal e pulmonar.


PURPOSE: to identify the symptoms of changes in the exhalation of asthmatic children. METHOD: this study was conducted with 30 children from 6 to 10 year-old, of both genders and with asthma clinical diagnosis confirmed by medical records and 30 non-asthmatic children from 6 to 10 year-old, of both genders, and with same age. We evaluated the nasal ventilation with Altmann millimeter nasal mirror measuring the nasal air escape in order to check their unilateral or bilateral air output and the relation of symmetry between the right and left nostril. The images were imported into the computer through HP scanner - Scanjet 2400 series. The analysis was performed by the Scion Image software for Windows (Alpha 4.0.3.2). All conclusions were based on a significance level of 5 percent, using Excel 2000 and SPSS v8.0 for the analysis. RESULTS: there were no significant differences between asthmatic and non-asthmatic children about the measurements of total area and the right and left nostril areas. CONCLUSION: there were no symptoms of changes in the exhalation of asthmatic children, being necessary a more specific study as for the nasal and pulmonary functions.

ABSTRACT

OBJETIVO: Caracterizar a atividade elétrica muscular do masseter durante a deglutição de líquido em indivíduos adultos jovens saudáveis. MÉTODOS: A população constou de 14 voluntários considerados saudáveis seguindo os critérios de inclusão e exclusão estabelecidos para esta pesquisa. Foi realizada avaliação eletromiográfica do músculo masseter bilateralmente, durante o repouso e nas tarefas de deglutição de 14,5 ml, 20 ml e 100 ml de líquido. O sinal eletromiográfico foi normalizado pela máxima atividade voluntária resistida (MAVR), considerada como 100 por cento de atividade elétrica muscular. RESULTADOS: No masseter direito, a maior média percentual foi encontrada na tarefa de deglutição de 20 ml e no masseter esquerdo na tarefa de 14,5 ml. No masseter direito ocorreu diferença entre as deglutições de 14,5 ml e 20 ml. No masseter esquerdo não houve diferença entre as tarefas de deglutição. CONCLUSÃO: A atividade elétrica muscular do masseter em adultos jovens saudáveis durante a deglutição de líquido pode ser influenciada pelo volume deglutido e apresenta diferentes respostas bilateralmente.


PURPOSE: To characterize the electrical activity of the masseter muscle during swallowing of liquids in healthy young adults. METHODS: Participants were 14 volunteers considered healthy according to the inclusion and exclusion criteria established for this study. The bilateral electromyographic evaluation of the masseter muscle was conducted at rest and in swallowing tasks of 14.5 ml, 20 ml and 100 ml of liquid. The electromyographic signal was normalized by the maximum voluntary activity resisted (MVAR), considered as 100 percent of the muscle's electrical activity. RESULTS: In the right masseter, the highest average percentage was found in the 20 ml task, and in the left masseter, in the 14.5 ml task. In the right masseter there was difference between the 14.5 ml and the 20 ml swallowing tasks. In the left masseter, no differences were found between the swallowing tasks. CONCLUSION: The electrical activity of the masseter muscle in healthy young adults during deglutition of liquids can be influenced by volume swallowed, and present different responses bilaterally.

ABSTRACT

Objetivos: caracterizar os padrões da antropometria facial em crianças asmáticas; identificar a presença de assimetrias faciais em crianças asmáticas e não asmáticas; e relacionar o lado de predomínio mastigatório com a presença de assimetria facial em crianças asmáticas e não asmáticas. MÉTODOS: participaram da pesquisa 60 crianças com idade entre 6 e 10 anos. Destas, 30 possuíam diagnóstico em prontuário de asma moderada ou grave e 30 crianças não apresentavam asma, fazendo parte do grupo controle. Foram realizadas avaliações antropométrica facial e da mastigação dessas crianças. RESULTADOS: em relação às mensurações antropométricas faciais nas crianças asmáticas e não-asmáticas não foram reveladas diferenças significativas entre os grupos. No que diz respeito à presença de assimetrias faciais, observou-se que estas ocorreram no grupo controle, assim como, no grupo asmático. O padrão mastigatório predominante em ambos os grupos foi o bilateral simultâneo e quando relacionados à assimetria facial e o predomínio mastigatório, não foram encontradas associações significantes. CONCLUSÃO: não foram encontradas diferenças significativas entre o grupo controle e o grupo asmático em relação às mensurações antropométricas. A assimetria facial foi observada nos dois grupos avaliados. Em ambos o padrão mastigatório bilateral simultâneo foi predominante, porém quando realizada a relação entre assimetria facial e o lado de predomínio mastigatório, não se observou relações significativas.


Purposes: to characterize the facial anthropometry patterns in asthmatic children; to identify the presence of facial asymmetry and to relate the prevalence of masticatory side with the presence of facial asymmetry in asthmatic and non-asthmatic children. METHODS: 60 children aged 6 to 10 years were evaluated. Thirty among them had a diagnosis of moderate or severe asthma and 30 children with no symptoms were the control group based on hospital's records. Facial anthropometric and chewing evaluations were carried through in these children. RESULTS: for facial anthropometric measurements in asthmatic and non-asthmatics children there were no significant differences between the groups but the finding of facial asymmetry was observed in both groups. The predominant masticatory pattern in both groups was the simultaneous bilateral and when it was related to facial asymmetry and masticatory predominance, there were no significant associations. CONCLUSION: no significant differences were found between the control and asthmatic group as for anthropometric measurements, however, the facial asymmetry was observed in the two groups. The simultaneous bilateral masticatory pattern was predominant in both groups, but the relation between facial asymmetry and the predominance of masticatory side were not significant.
