Hyoid displacement patterns in healthy swallowing

ABSTRACT Objective To describe the patterns of displacement of the hyoid bone in healthy individuals, considering their displacements during swallowing of different consistencies. Methods Two hundred one swallowing videofluoroscopy exams of 67 adult and elderly individuals without swallowing disorders were analyzed. Descriptive analysis was performed to identify and describe the patterns of displacement of the hyoid bone. Results Seven types of displacement of the hyoid bone were found: H1 (horizontal), H2 (short vertical and long horizontal), H3 (vertical and diagonal to upper), H4 (long vertical and short horizontal), H5 (vertical), H6 (diagonal), and H7 (brief). The standards were maintained in different consistencies. The most frequent pattern of displacement was type H2. The distribution of the types of displacement of the hyoid was different among men and women. Conclusion Seven patterns of displacement of the hyoid bone during swallowing of normal adults and older people have been described. The most frequent pattern of displacement was horizontal, with variations in distribution between men and women. The displacement pattern was maintained during the swallowing of the three different consistencies (thin, pasty and solid liquid).

Disfagia orofaríngea e a frequência de exacerbações em pacientes com Doença Pulmonar Obstrutiva Crônica com fenótipo exacerbador / Oropharyngeal dysfunction and frequency of exacerbation in Chronic Obstructive Pulmonary Disease patients with exacerbating phenotype

RESUMO Objetivo Avaliar se existe associação entre a presença de disfagia orofaríngea e a frequência de exacerbações em pacientes com doença pulmonar obstrutiva crônica (DPOC). Métodos Estudo transversal, para o qual foram recrutados pacientes com DPOC (Volume expiratório forçado no 1º segundo [VEF1]/Capacidade vital forçada [CVF] <0,7 após uso de broncodilatador), sem exacerbação dos sintomas nas últimas seis semanas, que realizavam acompanhamento ambulatorial e responderam ao questionário de autoavaliação para risco de disfagia. Além disso, foram submetidos à avaliação clínica e videofluoroscópica da deglutição. Resultados Vinte e sete pacientes com diagnóstico de DPOC responderam ao questionário de autoavaliação e realizaram a avaliação clínica da deglutição. Dezoito (66,7%) foram submetidos à avaliação instrumental por meio do exame de videofluoroscopia. A média de idade dos pacientes avaliados foi de 62,7 anos, sendo a maioria mulheres (63%), e mais da metade dos pacientes (70,4%) possuía fenótipo exacerbador. Observou-se associação significativa (p=0,039) entre os pacientes com diagnóstico de disfagia e o número de exacerbações no último ano. Conclusão A presença da disfagia orofaríngea deve ser considerada nos pacientes portadores de DPOC que apresentam o fenótipo exacerbador.

ABSTRACT Purpose To assess whether there is an association between the presence of oropharyngeal dysphagia and the frequency of exacerbations in patients with chronic obstructive pulmonary disease (COPD). Methods This is a cross-sectional study. Patients with COPD (forced expiratory volume in the first second [FEV1] / forced vital capacity [FVC] <0.7 after bronchodilator use) were recruited, with no exacerbation of symptoms in the last six weeks, who underwent outpatient follow-up and answered the questionnaire of self-assessment for risk of dysphagia. In addition, they underwent clinical and videofluoroscopic evaluation of swallowing. Results Twenty-seven patients diagnosed with COPD answered the self-assessment questionnaire and underwent the clinical evaluation of swallowing. Eighteen (66.7%) underwent instrumental evaluation through the videofluoroscopy exam. The mean age was 62.7 years, with the majority of females (63%) and more than half of patients (70.4%) having an exacerbator phenotype. A significant association (p = 0.039) was observed between patients diagnosed with dysphagia and the number of exacerbations in the last year. Conclusion The presence of oropharyngeal dysphagia should be considered in patients with COPD presenting an exacerbator phenotype.

Screening protocol for dysphagia in adults: comparison with videofluoroscopic findings

OBJECTIVES: To compare the videofluoroscopic findings of patients with suspected oropharyngeal dysphagia with the results of a clinical screening protocol. METHODS: A retrospective observational cohort study was conducted on all consecutive patients with suspected oropharyngeal dysphagia between March 2015 and February 2016 who were assigned to receive a videofluoroscopic assessment of swallowing. All patients were first submitted to videofluoroscopy and then to the clinical assessment of swallowing. The clinical assessment was performed within the first 24 hours after videofluoroscopy. The videofluoroscopy results were analyzed regarding penetration/aspiration using an 8-point multidimensional perceptual scale. The accuracy of the clinical protocol was analyzed using the sensitivity, specificity, likelihood ratios and predictive values. RESULTS: The selected sample consisted of 50 patients. The clinical protocol presented a sensitivity of 50% and specificity of 95%, with an accuracy of 88%. "Cough" and "wet-hoarse" vocal quality after/during swallowing were clinical indicators that appeared to correctly identify the presence of penetration/aspiration risk. CONCLUSION: The clinical protocol used in the present study is a simple, rapid and reliable clinical assessment. Despite the absence of a completely satisfactory result, especially in terms of the sensitivity and positive predictive values, we suggest that lower rates of pneumonia can be achieved using a formal dysphagia screening method.
