DEGLUTIÇÃO DE RESPIRADORES ORAIS E NASAIS: AVALIAÇÃO CLÍNICA FONOAUDIOLÓGICA E ELETROMIOGRÁFICA

PURPOSE: to evaluate and compare the swallowing of mouth and nose breathers through of speech-language and electromyography evaluation concerning the orbicularis oris muscles, and lower and upper lips. METHODS: 16 subjects aged 6:8 - 10:10 and divided on two groups participated in this study, one with mouth and another one with nose breathers. Both groups were submitted to clinical and surface electromyography evaluation. The speech-language evaluation contemplated the exam of the structures and functions of the stomatognathic system. The electromyography evaluation consisted of the captivation of the electrical activity at the orbicularis oris muscles, and lower and upper lips, during isometry and swallowing situations. In the clinical results were considered only the swallowing variables. Therefore, our study could observe the presence of labial and mentalis action and tongue projection, that were analyzed in a descriptive form. The statistical analysis of the electromyography results was done through the t test in order to compare the groups. The statistical considered significance was 5% (p<0.05). RESULTS: in the clinical evaluation it was verified that any of the nose breathers showed atypical swallowing characteristics while 7 (87.5%) of the mouth breathers showed labial action, 6 (75%) showed mentalis action and 6 (75%) showed tongue projection. In the electromyography evaluation, a higher muscular activity was verified, in the mouth breathers, when comparing to the nose breathers, in both lips, with a statistical significance. CONCLUSIONS: in this study it was verified that mouth breathers showed significant alterations in the swallowing functions when compared to the nose breathers that were observed through a clinical examination and electromyography evaluation.

Análise quantitativa do palato duro em diferentes tipologias faciais de respiradores nasais e orais

PURPOSE: to compare the hard palate dimensions in nasal and mouth breathing children of different facial typologies. METHOD: the sample comprised 54 children between seven and 11 year old, divided in two groups according to the facial type and breathing mode. The facial type was obtained through the Ricketts cephalometric analysis, and the breathing mode was determined from speech-language evaluation and otorhynolaryngologic diagnosis. In order to measure the transverse, vertical and anteroposterior length of the hard palate, plaster cast models of the children superior dental arch were obtained. To get the hard palate dimensions among the groups, parametric and nonparametric tests were used under a significance level of 5%. RESULTS: no statistically significant difference was found in hard palate measures among brachyfacial, mesofacial and dolichofacial children. A significant statistical difference in the distance among the second premolars was identified when compared with the different facial types of nasal and mouth breathing children, and such a difference was not detected in multiple comparisons. CONCLUSION: the dimensions of the hard palate did not show any difference when analyzed in different facial types regardless of the breathing mode. However, when analyzing the facial type in nasal and mouth breathers, we found a difference in the distance among the second premolars.

Alterações no modo respiratório, na oclusão e na fala em escolares: ocorrências e relações

PURPOSE: to check the occurrence of articulation disorders, alterations in breathing mode and malocclusion as well as the relation among theses variables in public-school children. METHODS: 308 female and male children aged between 6 and 11 years were submitted to speech pathologic and orthodontic evaluations, being selected 235. From the information collected in the evaluations, we considered: breathing mode, malocclusion by Angles classification and transverse alterations, as well as articulation disorder. RESULTS: 60.43% children had presented breathing mode alterations; 97.02% Angle malocclusion; 28.94% transverse occlusion alterations and 14.89% articulation disorder. Statistically significant relations were found between articulation disorder and transverse occlusion alterations, breathing mode and Angle malocclusion and between Angle malocclusion and transverse occlusion alterations. CONCLUSION: the malocclusions and alterations referring to breathing mode were frequent in the studied group. The found relationships reinforce the idea that there is a narrow relationship between the structure and the function of the stomatognathic system, and for that reason they deserve attention from several health professionals.

Childhood mouth-breathing consequences at adult age: ventilatory function and quality of life

Introduction Mouth breathing can affect the functions of the respiratory systems and quality of life. For this reason, children who grow up with this stimulus may have implications on physical and psychological aspects at adult age.Objective To evaluate childhood mouth-breathing consequences for the ventilatory function and quality of life at adult age.Materials and methods Prospective, observational and cross-sectional study with 24 adults, between 18 and 30 years old, mouth breathers during childhood, comprised the childhood mouth-breathing group (CMB). The childhood nasal-breathing (CNB) group was composed of 20 adults of the same age, without history of respiratory disease during all their lives. Measurements of maximal respiratory pressures, peak expiratory flow and 6-minute walk test were assessed. In addition, all the volunteers answered the Short Form-36 questionnaire (SF-36).Results The maximal inspiratory (p = 0.001) and expiratory (p = 0.000) pressures as well as the distance in the walk test (p = 0.003) were lower in the COB. The COB also presented lower score in the General Health domain of the SF-36 Questionnaire (p = 0.002).Conclusion Childhood mouth-breathing yields consequences for the ventilatory function at adult age, with lower respiratory muscle strength and functional exercise capacity. Conversely, the quality of life was little affected by the mouth breathing in this study.

Relação da respiração oral e hábitos de sucção não-nutritiva com alterações do sistema estomatognático

PURPOSE: to investigate the relationship between oral breathing of different etiologies and persisting non-nutritive sucking habits in establishing structural alterations in the stomatognathic system. METHOD: the sample comprised 78 children between 7 and 11 year old, 36 boys and 42 girls, divided in two groups based on non-nutritive sucking habits and breathing mode. All children underwent otolaryngological, speech-language and dentistry evaluations. Data analysis was performed using Chi-square test considering significance level of 5%. RESULTS: there was significant association between breathing mode and lips posture; between breathing mode and hard palate; between nonnutritive sucking habits and cheek posture. In the analysis of the association between breathing mode and nonnutritive sucking habits with the habitual lips posture and hard palate, we also forund a statistical significance. CONCLUSION: it was found that the altered lips posture and hard palate was more frequent in the vicious and obstructive mouth breathers groups. The asymmetrical cheeks posture was more frequent among children with habits. The altered lips posture and hard palate alterations were also more frequent in oral breathers regardless of the presence or absence of any habits.

Análise quantitativa do palato duro de respiradores orais: revisão de literatura

Mouth breathing generates many pathological adaptations in the orofacial structures and functions, such as alterations in the morphology of the hard palate. This structure actively participates in oral functions, deserving attention in the myofunctional orofacial evaluation, which have been increasingly using quantitative instruments. Even though the palate is difficult to be clinically assessed, little is known about the resources that can be used for quantitative evaluation of this structure. For this reason, we carried out this literature review, which had the aim to address the results of quantitative assessments of the palate of mouth breathers, as well as the instruments employed in these assessments. To this end, we reviewed national and international journals indexed in Medline, LILACS, Dentistry & Oral Sciences Source (EBSCO) and HighWire Press databases between 1983 and 2009. Based on the results of the studies retrieved, we concluded that mouth breathing was more frequently associated to an increase in palatal depth, and less frequently to a decrease in palatal width. Furthermore, it was verified that palatal evaluations used different measurement instruments, based on palatal measures obtained from plaster casts, directly in the mouth, or in cephalometric radiographs. It is believed that the methods of quantitative assessment reviewed can contribute to a precise speech-language pathology diagnosis.

Avaliação da profundidade do palato duro: correlação entre método quantitativo e qualitativo

PURPOSE: to investigate the correlation between quantitative and qualitative methods of hard palate depth evaluation. METHOD: 74 children participated in this study. They were in mixed dentition phase and were evaluated by speech therapist and dentist, who made the plaster models of maxillary dental arch used later for measure. The quantitative method was measurement of molar distance and molar depth whose values were used to calculate the Palatal Height Index. The hard palate was classified into low medium and high palate. Qualitative analysis was performed through visual inspection of the plaster models by three speech therapists with experience in Orofacial Myology. The depth of hard palate was classified as low, normal or increased. The result was the consensus of at least two evaluators. For Data analysis the frequency of ratings was investigated and the Gamma Correlation Test was applied. RESULTS: qualitative method: medium palate (55,4%) followed by low palates (39,2%) and high palate (5,4%). Quantitative method: high palates (51,4%) followed by medium palate (43,2%) and low palates (5,4%). The Gamma Correlation Test resulted in 0,6212 (p<0,05) which indicates moderate correlation. CONCLUSION: the correlation between quantitative and qualitative methods of hard palate assessment was moderate. There was a trend in the qualitative evaluation to consider the palates deeper than the quantitative method. Therefore, it is suggested that both forms of analysis to be used in clinical practice.

Contribuição da ausculta cervical para a avaliação clínica das disfagia orofaríngeas

In order to assist on the functional assessment of swallowing, most speech therapists make use of instrumental resources such as cervical auscultation. Thus, the objective of this study was to search the literature in order to find the contribution of cervical auscultation for assessing dysphagias. To this end, international and national journals were reviewed. These journals were indexed in Springer, Lilacs, Bireme, Medline and Scielo databases, comprising the period between 1992 and 2011. From the analysis of the studies, it was possible to verify that: cervical auscultation has been modernized with the technologic evolution, enabling the realization of quantitative studies of the swallowing sounds; there are still few clear evidence of the connections between the sound components of swallowing and the physiological events of the pharyngeal phase; no differences were observed between the swallowing sounds in children and adults; in some studies, cervical auscultation was positively correlated with the videofluoroscopic assessment of swallowing, and others presented positive correlation between these two assessment procedures. Hence, considering that the swallowing videofluoroscopy examination is still difficult to access, with relatively high cost, it is believed that cervical auscultation constitutes an important resource for the diagnosis and clinical monitoring in cases of oropharyngeal dysphagia.

Correlation between nasopharyngoscopy and cephalometry in the diagnosis of hyperplasia of the pharyngeal tonsils

Summary Introduction: Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing, and accurate diagnosis of this alteration is important for proper therapeutic planning. Therefore, studies have been conducted in order to provide information regarding the procedures that can be used for the diagnosis of pharyngeal obstruction. Objective: To verify the correlation between nasopharyngoscopy and cephalometric examinations in the diagnosis of pharyngeal tonsil hyperplasia. Method: This was a cross-sectional, clinical, experimental, and quantitative study. Fifty-five children took part in this study, 30 girls and 25 boys, aged between 7 and 11 years. The children underwent nasofibropharyngoscopic and cephalometric evaluation to determine the grade of nasopharyngeal obstruction. The Spearmans rank correlation coefficient at the 5% significance level was used to verify the correlation between these exams. Results: In the nasopharyngoscopy evaluation, most children showed grade 2 and 3 hyperplasia of the pharyngeal tonsil, which was followed by grade 1. In the cephalometry assessment, most children showed grade 1 hyperplasia of the pharyngeal tonsil, which was followed by grade 2. A statistically significant regular positive correlation was observed between the exams. Conclusion: It was concluded that the evaluation of the pharyngeal tonsil hyperplasia could be carried out by fiber optic nasopharyngoscopy and cephalometry, as these examinations were regularly correlated. However, it was found that cephalometry tended to underestimate the size of the pharyngeal tonsil relative to nasopharyngoscopy.
