de la deglución, los cuales representan todas las alteraciones del proceso fisiológico encargado de llevar el alimento desde la boca al esófago y después al estómago, salvaguardando siempre la protección de las vías respiratorias. OBJETIVO. Definir el manejo óptimo, de la disfagia en pacientes con antecedente de infección severa por COVID-19. METODOLOGÍA. Se realizó una revisión de la literatura científica en las bases de datos PubMed y Elsevier que relacionan el manejo de la disfagia y pacientes con antecedente de infección severa por SARS-CoV-2. Se obtuvo un universo de 134 artículos que cumplieron los criterios de búsqueda. Se seleccionaron 24 documentos, para ser considerados en este estudio. RESULTADOS. La incidencia de disfagia posterior a infección severa por SARS-CoV-2 fue del 23,14%, siendo la disfagia leve la más frecuente 48,0%. Los tratamientos clínicos más empleados en el manejo de la disfagia fueron rehabilitación oral y cambio de textura en la dieta en el 77,23% de los casos, mientras que el único tratamiento quirúrgico empleado fue la traqueotomía 37,31%. Un 12,68% de pacientes recuperó su función deglutoria sin un tratamiento específico. La eficacia de los tratamientos clínicos y quirúrgicos en los pacientes sobrevivientes de la infección severa por SARS-CoV-2 fue del 80,68%, con una media en el tiempo de resolución de 58 días. CONCLUSIÓN. La anamnesis es clave para el diagnóstico de disfagia post COVID-19. El tratamiento puede variar, desde un manejo conservador como cambios en la textura de la dieta hasta tratamientos más invasivos como traqueotomía para mejorar la función deglutoria.

INTRODUCTION. The difficulty to swallow or dysphagia is included within the problems of swallowing, which represent all the alterations of the physiological process in charge of carrying the food from the mouth to the esophagus, and then to the stomach, always taking into account the protection of the airways. OBJECTIVE. To define the optimal management, both clinical and surgical, for the adequate treatment of dysphagia produced as a consequence of severe SARS-CoV-2 infection. METHODOLOGY. A review of the scientific literature was carried out using both PubMed and Elsevier databases, which relate the management of dysphagia and patients with a history of severe SARS-CoV-2 infection. RESULTS. The incidence of dysphagia following severe SARS-CoV-2 infection was of 23,14%, with mild dysphagia being the most frequent 48,00%. The most frequently used clinical treatments for dysphagia management were oral rehabilitation and change in dietary texture in 77,23% of cases, while tracheotomy was the only surgical treatment used 37,31%. A total of 12,68% of patients recovered their swallowing function without specific treatment. The efficacy of clinical and surgical treatments in survivors of severe SARS-CoV-2 infection was 80,68%, with a mean resolution time of 58 days. CONCLUSION. An adequate medical history is key to the diagnosis of post-COVID-19 dysphagia. Treatment can range from conservative management such as changes in diet texture to more invasive treatments such as tracheotomy to improve swallowing function.

Impacto de la cánula nasal de alto flujo y la ventilación no invasiva en la fisiología deglutoria: revisión de la literatura / Impact of high-flow nasal cannula and non-invasive ventilation on swallowing physiology: a literature review

El proceso deglutorio requiere de una adecuada coordinación entre respiración y deglución. En el contexto clínico, el uso de dispositivos ventilatorios no invasivos, como la cánula nasal de alto flujo (CNAF) o la ventilación no invasiva (VNI), ha cobrado gran relevancia durante los últimos años. Sin embargo, existe escasa información respecto a la interferencia que estos dispositivos podrían ocasionar en la fisiología deglutoria. En este contexto, y con el objetivo de describir el impacto de la CNAF y la VNI en la fisiología deglutoria, se realizó una revisión de la literatura en PubMed, Medline, Embase, Web of Science, Lilacs y Scielo. Se incorporaron estudios que incluyeran población ≥18 años, con uso de CNAF o VNI. Se excluyeron estudios en población con antecedentes de disfagia, necesidad de intubación, presencia de enfermedad neurológica, neuromuscular o respiratoria, entre otros. Los resultados de los estudios muestran que la CNAF podría disminuir el número de degluciones (en flujos ≥ 20 L/min; p<0,05),disminuir el tiempo medio de activación de la respuesta deglutoria proporcional al flujo empleado (p<0,05), incrementar el riesgo aspirativo en flujos altos (>40 L/min, p<0,05) e incrementar en promedio la duración del cierre del vestíbulo laríngeo (p<0,001). La VNI modo BiPAP, por su parte, podría aumentar el riesgo aspirativo debido al incremento en la tasa de inspiración post deglución (SW-I, p<0,01). Si bien la evidencia disponible es limitada, los resultados aportan información relevante a considerar en el abordaje de usuarios que utilicen estos dispositivos ventilatorios. Futuras investigaciones deberían ser desarrolladas para fortalecer la evidencia presentada.

Deglutition requires adequatecoordination between breathing and swallowing. In the clinical context, the use of non-invasive ventilatory devices such as high-flow nasal cannulas(HFNC) or non-invasive ventilation (NIV) has become highlyrelevantin recent years. However, there is little information regarding howthese devices could interferewith the physiologyof deglutition. This study aimedto describe the impact of HFNC and NIV on swallowing physiology. To this end, aliterature review was carried out usingPubMed, Medline, Embase, Web of Science, Lilacs,and Scielo. Studies performed onpopulations≥18 years old where HFNC or NIV were used were included. Studies where thepopulation hada history of dysphagia, need for intubation, and presentedneurological, neuromuscular,or respiratory diseases, among others, were excluded. The results show that HFNC could decrease the swallowing rate(with flows≥ 20 L/min; p<.05), decrease the mean activation time of the swallowing reflex in proportion to the flow (p<.05), increase the risk of aspiration when usinghigherflows (>40 L/min, p<0.05),and increase the average duration of the laryngeal vestibuleclosure(p<.001).NIV, particularly BiPAP, could increase the risk of aspiration due to the higherrate of post-swallowing inspiration (SW-I, p<.01). Although the evidence available on this matter is limited, theseresults offerrelevant information that should beconsideredwhen working with patients who use these ventilatory devices. Furtherresearch should be carriedoutto strengthen the evidence that is provided in this study.

Introduction: Tracheostomy may impact swallowing and generate neurophysiological and mechanical alterations. Objective: To analyze the swallowing functionality in tracheostomized patients admitted to a university hospital, before and after speech-language therapy intervention through the analysis of the service protocols - Adapted Protocol (based on the FOIS scale and Dysphagia Risk Assessment Protocol - PARD). Method: Cross-sectional, retrospective, analytical observational study, with a quantitative approach. We analyzed 114 swallowing assessment protocols, and checked the degree of dysphagia according to O'Neil's classification and FOISscale over a four-year period. Research approved by the Institution's Research Ethics Committee (29894920.5.0000.5349). Results: After analyzing the protocols it was found that the majority were male with a mean age of 54.55 years. A predominance of the following previous health comorbidities was observed: pneumonia, systemic arterial hypertension and ischemic stroke. After the speech-language therapy follow-up there was an improvement in swallowing biomechanics with more patients presenting functional swallowing - one (0.9%) to 12 (10.5%), reduction in the number of subjects with severe dysphagia - 32 (28.1%) to 17 (14.9%) and greater oral intake - 79 (69.3%) of the patients increased the level of oral intake according to the FOIS scale. Most of the sample showed good tolerance to tracheostomy occlusion and 60 (52.6%) progressed to decannulation. Conclusion: The presence of a tracheostomy had an impact on swallowing functionality, since most patients had some degree of dysphagia. We emphasize the importance of speech therapy in the swallowing rehabilitation process, helping in the decannulation process.

El odontólogo, custodio de la función masticatoria / The dentist, guardian of masticatory function

La masticación tiene como objetivo la adecuada preparación de los alimentos para su deglución y digestión. Cualquier alteración en el sistema estomatognático puede deteriorar la masticación. El odontó- logo es el profesional responsable de mantener y/o restaurar la función masticatoria. La evaluación de la función masticatoria puede hacerse de forma subjetiva utilizando cuestionarios para medir la percepción del paciente sobre su capacidad masticatoria o de forma objetiva analizando la fuerza oclusal, la actividad electromiográfica de los músculos mas- ticadores, la trayectoria de la mandíbula al masticar o la capacidad de trituración de los alimentos. Estos métodos se utilizan en proyectos de investigación, pero en la clínica ¿evaluamos si existe alguna alteración al masticar y al finalizar el tratamiento si cumplimos con el objetivo de restaurar la función masticatoria? ¿Realmente nos preocupamos por mantener y/o restaurar la función masticatoria? Por lo general no, ni en los consultorios, ni en las clínicas universitarias. Es esencial que nos concienticemos de nuestra responsabilidad y para ello es necesario que se le dé mayor peso curricular a la función masticatoria y cómo evaluarla. Seamos realmente custodios de la función masticatoria de nuestros pacientes (AU)

The goal of chewing is to properly prepare food for swallowing and digestion. Any problem in the stomatognathic system can deteriorate chewing. The professional responsible of maintaining and/or restoring masticatory function is the dentist. Masticatory function can be evaluated subjectively through questionnaires to measure the patient's perception of his/her masticatory capacity or objectively analyzing occlusal force, the electromyographic activity of the masticatory muscles, the movements of the mandible during chewing or the individual's capacity to breakdown food. These methods are used in research projects but, do we examine if there is any problem during chewing and if we are achieving our goal of restoring masticatory function at the end of the treatment in our offices? Do we really focus on maintaining and/or restoring masticatory function? Not truly, not in our offices or university clinics. It is imperative that we acknowledge our responsibility but for that it is essential that masticatory function and how to evaluate it is given more weight in the curriculum. Let us be genuine guardians of the masticatory function of our patients (AU)

Correlação entre ausculta cervical e eletromiografia de superfície na fase faríngea da deglutição / Correlation between cervical auscultation and electromyography in the pharyngeal phase of swallowing / Correlación entre auscultación cervical y electromiografía de superficie en la fase faríngea de la deglución

Objetivo: Correlacionar os dados acústicos da ausculta cervical com a atividade elétrica dos músculos envolvidos na fase faríngea da deglutição. Métodos: Trata-se de um estudo observacional, transversal, de abordagem quantitativa, aprovado em janeiro pelo CEP/UFSCPA (número 1.389.050). Todos os participantes do estudo assinaram o termo de consentimento livre e esclarecido. A fase faríngea da deglutição foi avaliada por meio de ausculta cervical e eletromiografia de superfície. Os indivíduos ingeriram 90 ml de água. Os dados da ausculta foram transferidos para o DeglutiSom® software, a duração e amplitude da atividade eletromiográfica foram mensuradas durante a deglutição com aparelho de eletromiografia de superfície Miotec®. O nível de significância adotado foi de 5%. Resultados:Cinquenta e sete mulheres participaram deste estudo. A média de idade foi de 23,4 anos. Ressalta-se que quanto maior a frequência média do pico da ausculta, menor é a média do pico do músculo supra-hióideo e quanto maior a intensidade, maior é o pico, assim como a média dos picos supra-hióideos. Foi possível demonstrar que o pico de atividade do músculo supra-hióideo foi significativamente maior do que o pico de atividade do músculo infra-hióideo para a deglutição de 90 ml de água. Conclusão:Os parâmetros acústicos da deglutição em indivíduos saudáveis estão correlacionados com a atividade elétrica dos músculos envolvidos na fase faríngea da deglutição.

Objective: Correlate the acoustic data of cervical auscultation to the electrical activity of the muscles involved in the pharyngeal phase of swallowing. Methods: This is an observational, cross-sectional study involving a quantitative approach and was approved on January by CEP/UFSCPA (number 1.389.050). All participants of the study signed an informed consent form. The pharyngeal phase of swallowing was assessed by employing auscultation and surface electromyography. Individuals ingested 90 ml of water. The auscultation data were transferred to DeglutiSom® software, the duration and amplitude of electromyographic activity was measured during swallowing using a Miotec® surface electromyography device. The level of significance adopted was 5%. Results: Fifty-seven women participated in this study. The average age was 23.4 years on average. It must be highlighted that the greater the average peak frequency of auscultation, lower was the average peak of the suprahyoid muscle and the greater the intensity, the greater was the peak, as well as the average of the suprahyoid peaks. It was possible to demonstrate that the peak of suprahyoid muscle activity was significantly higher than the peak of infra hyoid muscle activity for swallowing 90 ml of water. Conclusion: The acoustic swallowing parameters in healthy individuals are correlated with the electrical activity of muscles involved in the pharyngeal phase of swallowing.

Los datos de auscultación fueron cargados em el software DeglutiSom®, la duración y la amplitud de la actividad electromiográfica se midió durante la deglución utilizando un dispositivo de electromiografía de superficie Miotec®. El nivel de significancia adoptado fue del 5%. Resultados: Cincuenta y siete mujeres participaron en este estudio. La edad promedio fue 23,4 años. Cabe destacar que a mayor frecuencia de pico promedio de auscultación, menor fue el pico promedio del músculo suprahioideo y a mayor intensidad, mayor fue el pico, así como el promedio de los picos suprahioideos. Fue posible demostrar que el pico de actividad del músculo suprahioideo era significativamente más alto que el pico de actividad del músculo infrahioideo para tragar 90 ml de agua. Conclusión: Los parámetros de deglución acústica en individuos sanos se correlacionan con la actividad eléctrica de los músculos involucrados en la fase faríngea de la deglución.

Análise da mastigação e deglutição na paralisia cerebral com deficiência visual: estudo de caso / Analysis of chewing and swallowing in cerebral palsy with a visual impairment: study of case / Análisis de la masticación y la deglución en la parálisis cerebral con discapacidad visual: un estudio de caso

Introdução: A Paralisia Cerebral pode acarretar alterações em qualquer uma das fases da deglutição, causando uma disfagia neurogênica. No entanto, desordem neurológica e deficiência visual associada é um tema pouco estudado. A criança com a ausência do canal visual, geralmente tem pouca noção na estrutura do espaço e até mesmo em relação à sua estrutura corporal e organizacional. É sabido que a Paralisia Cerebral discorre atrasos no padrão mastigatório e da deglutição, mas questiona-se se a deficiência visual pode interferir ou não neste desempenho. Objetivo: O propósito deste estudo foi analisar as funções de mastigação e o tempo de deglutição em criança com paralisia cerebral e deficiência visual associada. Método: Esta pesquisa é de natureza exploratória e descritiva, desenvolvida por meio de um estudo de caso clínico de uma criança com paralisia cerebral e deficiência visual associada. Três consistências de alimento foram examinadas: líquido (suco), pastosa (iogurte) e sólido (pão), sendo cronometrado o tempo gasto para deglutir cada uma delas, durante o horário normal de alimentação. Resultados: os resultados mostraram que a criança com Paralisia Cerebral e Deficiência Visual apresenta dificuldades na função de mastigação e leva mais tempo para deglutir nas consistências sólida e líquida. Conclusão: A deficiência visual associada à paralisia cerebral pode acentuar na dificuldade das funções de mastigação e deglutição.

Introduction: Cerebral Palsy can cause changes in any of the phases of swallowing, causing neurogenic dysphagia. However, neurological disorder and associated visual impairment is a poorly studied topic. The child with the absence of the visual channel, generally has little idea of the structure of the space and even of its body and organizational structure. It is known that Cerebral Palsy has delays in chewing and swallowing patterns, but it is questioned whether visual impairment can interfere or not in this performance. Objective: The purpose of this study was to analyze chewing functions and swallowing time in children with cerebral palsy and associated visual impairment. Method: This research is exploratory and descriptive in nature, developed through a clinical case study of a child with cerebral palsy and associated visual impairment. Three food consistencies were examined: liquid (juice), pasty (yogurt) and solid (bread), with the time spent swallowing each of them during the normal feeding time being timed. Results: the results showed that the child with Cerebral Palsy and Visually Impaired presents difficulties in chewing function and takes more time to swallow in solid and liquid consistencies. Conclusion: Visual impairment associated with cerebral palsy may accentuate the difficulty in chewing and swallowing functions.

Introducción: La parálisis cerebral puede provocar cambios en cualquiera de las fases de la deglución, provocando disfagia neurogénica. Sin embargo, el trastorno neurológico y la discapacidad visual asociada es un tema poco estudiado. El niño con ausencia del canal visual, generalmente tiene poca idea de la estructura del espacio e incluso de su cuerpo y estructura organizativa. Se sabe que la parálisis cerebral tiene retrasos en los patrones de masticación y deglución, pero se cuestiona si la discapacidad visual puede interferir o no en este desempeño. Objetivo: El propósito de este estudio fue analizar las funciones de masticación y el tiempo de deglución en niños con parálisis cerebral y discapacidad visual asociada. Método: Esta investigación es de naturaleza exploratoria y descriptiva, desarrollada a través de un estudio de caso clínico de un niño con parálisis cerebral y discapacidad visual asociada. Se examinaron tres consistencias de alimentos: líquido (jugo), pastoso (yogur) y sólido (pan), y se pasó el tiempo de deglución de cada uno de ellos durante el tiempo normal de alimentación. Resultados: los resultados mostraron que el niño con parálisis cerebral y deficiencia visual tiene dificultades en la función de masticación y toma más tiempo para tragar en forma sólida y líquida. Conclusión: la discapacidad visual asociada con la parálisis cerebral puede acentuar la dificultad en las funciones de masticación y deglución.

Manual para evaluar la deglución y el rendimiento masticatorio en las clínicas de odontología / Manual to evaluate swallowing and chewing performance in dental clinics

Objetivo: desarrollar y aplicar un manual para evaluar los procesos de deglución y rendimiento masticatorio, dirigido a estudiantes y profesionales de odontología. Método: se realizó un estudio con enfoque cuali-cuantitativo, a partir de dos técnicas de recolección de información: documental para reunir información de los procedimientos y observacional para la aplicación del manual. Los métodos seleccionados fueron el rendimiento masticatorio (Albert T) y de deglución (Técnica Payne); el diseño se esbozó según la metodología para mejorar la calidad de los procesos y una guía técnica de elaboración de manuales de procedimientos en salud. Así, el manual cuenta con introducción, antecedentes históricos, alcance y objetivo, flujograma, descripción de procedimientos de evaluación de la deglución, del rendimiento masticatorio y bibliografía. Este fue aplicado en 27 pacientes de la clínica de ortodoncia, a quienes se les diagnosticó deglución atípica, y se midió el rendimiento masticatorio para conocer la mediana de tamaño de partícula (MTP) de cada individuo. Resultados: el manual se realizó basándose en dos procedimientos, uno con el diagnóstico de deglución y otro con rendimiento masticatorio. Este último fue aplicado por dos estudiantes investigadores a una muestra de 27 pacientes, cuyo resultado fue una mediana de tamaño total de partícula de MTP = 5.35 mm2. Hubo una diferencia estadísticamente significativa entre sexos (MTP en hombres: 6,0 mm2 y mujeres 5.1 mm2) siendo las mujeres quienes presentaron mejor desempeño masticatorio. Conclusión: al aplicar el manual, los estudiantes evaluaron el rendimiento masticatorio y la deglución, con lo cual lograron resultados medibles, aplicables y reproducibles.

Objective: To apply a manual to evaluate swallowing and chewing performance aimed at dental students and professionals. Method: A study was carried out with a qualitative-quantitative approach developing two information gathering techniques: documentary to gather information on procedures and observational in the application of the manual. The methods of chewing performance (Albert T) and swallowing (Payne Technique) were selected; the design was outlined according to the methodology to improve the quality of the processes and a technical guide for the elaboration of manuals of health procedures; in the development phase, the thematic units were created and the manual was prepared with: cover, back cover, authors, introduction, historical background, scope and objective, flow chart, description of swallowing evaluation procedures, chewing performance and bibliography; this was applied to 27 patients from the orthodontic clinic, who were diagnosed with atypical swallowing, and the masticatory performance was measured to determine the median particle size (MTP) of each individual evaluated. Results: The manual was made based on two procedures, one with swallowing diagnosis and the other with masticatory performance, which was applied by two student researchers to a sample of 27 patients, yielding a median total particle size of MTP = 5.35 mm2. There was a statistically significant difference between the sexes (MTP in men: 6.0 mm2 and women 5.1 mm2), with women presenting the best masticatory performance Conclusion: when applying the manual, the students evaluated the chewing performance and swallowing, achieving measurable, applicable and reproducible.

RESUMO Objetivo Descrever e caracterizar um achado, o escape posterior tardio de resíduo alimentar na deglutição, segundo idade, gênero e consistência do alimento, que ocorreu no evento. Método A coleta de dados ocorreu por meio da análise de cada exame de videonasoendoscopia funcional da deglutição anteriormente gravado em um ambulatório especializado. A população do estudo contemplou 200 pacientes de ambos os gêneros, na faixa etária entre 46 e 87 anos, com e sem patologia de base para disfagia. As imagens foram estudadas individualmente pelo pesquisador e analisadas por juízes, com o objetivo de identificar e selecionar imagens que constatassem a presença ou ausência do evento em estudo. Resultados Verificou-se o escape tardio em 45 exames do total de 200 analisados. Os exames selecionados para o estudo apresentaram o escape residual posterior tardio em pelo menos uma consistência. A maior frequência do escape posterior tardio ocorreu com o líquido. A análise mostrou significância do evento em estudo com a população que apresentava idades mais avançadas da nossa amostra. Conclusão O escape posterior tardio ocorre predominantemente na consistência líquida, em população mais idosa e sem predomínio de gênero.

ABSTRACT Purpose To describe and characterize a finding, i.e., delayed posterior leakage of food residue during swallowing, according to age, gender and food consistency, which occurred in the event. Methods Data were collected through the analysis of each functional videonasoendoscopy test of swallowing previously recorded in a specialist outpatient clinic. The study population included 200 patients, both males and females, aged between 46 and 87 years, with and without an underlying pathology for dysphagia. The images were studied individually by the researcher and analyzed by judges in order to identify and select images that would confirm the presence or absence of the study event. Results Delayed escape was found in 45 out of the 200 analyzed tests. The tests selected for the study showed delayed posterior bolus leakage in at least one consistency. The highest frequency of delayed posterior leakage occurred with fluids. The analysis showed the significance of the study event with the population related to older ages in the sample analyzed. Conclusion Delayed posterior leakage occurs predominantly in the liquid consistency in older populations with no gender predominance.

The influence of malocclusion, sucking habits and dental caries in the masticatory function of preschool children

Abstract The aim of this study was to evaluate the association of malocclusion, nutritive and non-nutritive sucking habits and dental caries in the masticatory function of preschool children. A cross-sectional study was conducted with a sample of 384 children aged 3-5 years. A single examiner calibrated for oral clinical examinations performed all the evaluations (kappa > 0.82). Presence of malocclusion was recorded using Foster and Hamilton criteria. The number of masticatory units and of posterior teeth cavitated by dental caries was also recorded. The parents answered a questionnaire in the form of an interview, addressing questions about the child's nutritive and non-nutritive sucking habits. The masticatory function was evaluated using Optocal test material, and was based on the median particle size in the masticatory performance, on the swallowing threshold, and on the number of masticatory cycles during the swallowing threshold. Data analysis involved simple and multiple linear regression analyses, and the confidence level adopted was 95%. The sample consisted of 206 children in the malocclusion group and 178 in the non-malocclusion group. In the multiple regression analysis, the masticatory performance was associated with age (p = 0.025), bottle feeding (p = 0.004), presence of malocclusion (p = 0.048) and number of cavitated posterior teeth (p = 0.030). The swallowing threshold was associated with age (p = 0.025), bottle feeding (p = 0.001) and posterior malocclusion (p = 0.017). The number of masticatory cycles during the swallowing threshold was associated with the number of cavitated posterior teeth (p = 0.001). In conclusion, posterior malocclusion, bottle feeding and dental caries may interfere in the masticatory function of preschool children.

Swallowing, voice and quality of life of patients submitted to extended supratracheal laryngectomy / Deglutição, voz e qualidade de vida de pacientes submetidos à laringectomia supratraqueal alargada

ABSTRACT Objective To describe functional and quality of life results after extended supratracheal laryngectomy. Methods In the period from September 2009 to January 2018, 11 male subjects were submitted to extended supratracheal laryngectomy. Swallowing abilities were assessed through videofluoroscopy and the clinical scale Functional Communication Measures of Swallowing. The voices were classified by means of the perceptual-auditory analysis Consensus Auditory-Perceptual Evaluation of Voice. All subjects completed a self-assessment questionnaire for voice and swallowing. Results Aspiration was found in four patients and all presented stasis in different structures. All subjects in this study were exclusively orally fed and hydrated. In the evaluation of quality of life in swallowing, patients had mean >80 in all areas (83.47 mean of scores). The general degree and the presence of roughness were the highest means present in Consensus Auditory-Perceptual Evaluation of Voice (37.81 and 49.36, respectively). The mean of 33.36 (±22.56) had little impact on quality of life under the perspective of vocal aspects. Conclusion After supratracheal laryngectomy, swallowing was sufficiently restored and the quality of life was satisfactory. The voice presents severely impaired quality and preserved oral communication, with low impact on the activities of daily living. All individuals who maintained two cricoarytenoid units presented better functional results in swallowing and voice.

RESUMO Objetivo Descrever os resultados funcionais e de qualidade de vida após a laringectomia supratraqueal alargada. Métodos No período de setembro de 2009 a janeiro de 2018, 11 indivíduos do sexo masculino foram submetidos à laringectomia supratraqueal alargada. As habilidades de deglutição foram avaliadas por meio da videofluoroscopia e da escala clínica Functional Communication Measures . As vozes foram classificadas por análise perceptivo-auditiva da Consensus Auditory-Perceptual Evaluation of Voice . Todos os voluntários preencheram um questionário de autoavaliação para voz e deglutição. Resultados A aspiração foi encontrada em quatro pacientes, e todos apresentaram estase em diferentes estruturas. Todos os sujeitos deste estudo apresentavam alimentação e hidratação exclusivas por via oral. Na avaliação da qualidade de vida na deglutição, os pacientes demonstraram médias >80 em todas as áreas (83,47 média dos escores). O grau geral e a presença de rugosidade foram os maiores escores médios na avaliação perceptivo-auditiva da voz (37,81 e 49,36 consecutivamente). A média de 33,36 (±22,56) demonstrou pouco impacto na qualidade de vida sob a perspectiva dos aspectos vocais. Conclusão Após a laringectomia supratraqueal, a deglutição foi suficientemente restaurada, e a qualidade de vida foi satisfatória. A voz apresenta qualidade gravemente comprometida com comunicação oral preservada, demonstrando baixo impacto nas atividades da vida diária. Todos os indivíduos que mantiveram duas unidades cricoaritenóideas apresentaram melhores resultados funcionais na deglutição e na voz.

Tongue function and swallowing in individuals with temporomandibular disorders

Abstract The tongue participates in the oral phase of swallowing by pushing the food bolus toward the oropharynx. This relationship between tongue function and swallowing is little addressed addressed in individuals with temporomandibular dysfunction (TMD). Objective: To analyze the association of functional tongue conditions on swallowing in individuals with TMD. Methodology: After approval by the Institutional Review Board, the study was conducted on 30 individuals of both sexes, aged 18 to 28 years, with TMD, and not treated for the disorder. Tongue function was assessed as to the mobility, pressure, and oral motor control. Swallowing was analyzed by clinical assessment during ingestion of solid (wafer biscuit) and liquid (water). Data regarding mobility and swallowing were collected using the orofacial myofunctional evaluation protocol. Tongue pressure was measured by the Iowa Oral Performance Instrument, during elevation, protrusion, swallowing, and resistance test. The oral motor control was assessed by the oral diadochokinesis (DDK) test by rapid and repeated emissions of syllables "ta" and "ka". Data were statistically analyzed by the Spearman correlation coefficient, at a significance level of 5%. Results: Relationships were found between tongue function and swallowing for the following aspects: mobility (r=0.741), pressure in protrusion (r=-0.366), swallowing of saliva (r=-0.499), mean DDK rate in emissions "ta" (r=-0.424) and "ka" (r=-0.446), and mean DDK period in emissions "ta" (r=0.424) and "ka" (r=0.446). Thus, the greater the change in tongue mobility, the lower the tongue pressure in protrusion and swallowing of saliva, the lower the emissions per second, the longer the mean time between vocalizations, and the worse the swallowing of individuals with TMD. Conclusion: The functional conditions of the tongue regarding mobility, pressure, and oral DDK were associated with swallowing in individuals with TMD.

Ultrasonido para la evaluación de la deglución: una revisión narrativa / Ultrasound for swallowing asessment: narrative review

El presente estudio explora evidencia sobre la evaluación de la deglución, usando la técnica de ultrasonido. En relación a la estrategia búsqueda, la revisión se desarrolló en PubMed y Scielo, utilizando una adaptación de las recomendaciones del manual Cochrane para revisiones sistemáticas. Se seleccionaron los términos "Deglutition" "Swallowing", "Ultrasonography" y "Ultrasound" en inglés y en español. Se incluyeron inicialmente estudios originales publicados entre enero del 2000 y enero del 2019. De acuerdo con los criterios de elegibilidad, se incluyeron 24 artículos originales sobre el uso de ultrasonido para evaluar algún aspecto de la deglución en las etapas oral y faríngeas. Los artículos seleccionados ofrecen datos cuantitativos de parámetros e indicadores de la deglución. A partir de estos estudios, se recogió información cualitativa y cuantitativa sobre la movilidad lingual, la elevación laríngea, la movilidad faríngea lateral, la movilidad del hioides, la movilidad del músculo genihioideo, la apertura del esfínter esofágico superior, el cierre glótico, además de estudios sobre la posibilidad de detectar episodios de penetración laríngea y aspiración. Los resultados sugieren que existe evidencia positiva sobre la utilidad del ultrasonido para evaluar la deglución, sin embargo, se requiere de más estudios que analicen la eficiencia diagnóstica en población con disfagia.

The present study explores evidence on swallowing assessment using ultrasound technique. Regarding the search strategy, the review was carried out in PubMed and Scielo, using an adaptation of the recommendations from the Cochrane manual for systematic reviews. The terms "Deglutition" "Swallowing", "Ultrasonography" and "Ultrasound" were selected in English and Spanish. Original studies published between January 2000 and January 2019 were initially selected. According to the elegibility criteria, 24 original studies dealing with the use of ultrasound to evaluate some aspect of swallowing in both oral and pharyngeal stages. Selected articles offer quantitative data on swallowing parameters and indicators. From these studies, qualitative and quantitative information on lingual mobility, laryngeal elevation, lateral pharyngeal mobility, hyoid mobility, genihyoid muscle mobility, upper esophageal sphincter opening, glotic closure was collected, in addition to studies on the possibility of detecting episodes of laryngeal penetration and aspiration. The results suggest that there is positive evidence on the usefulness of ultrasound to assess swallowing, however, more studies are required to analyze diagnostic efficiency in a population with dysphagia.

INTRODUCCIÓN: La escala Early Feeding Skills (EFS) evalúa la conducta del neonato antes, durante y posterior al proceso de alimentación. OBJETIVOS: Determinar la validez de fachada, de contenido y evaluar con dicha escala el proceso de alimentación en los recién nacidos prematuros comparando con variables relevantes. PPACIENTES Y MÉTODO: Se evaluaron prematuros de 34 a 36 semanas de edad corregida sin daño neurológico o malformaciones craneofaciales. Diseño de tipo descriptivo de corte transversal. Los datos fueron obtenidos mediante escala EFS, versión corregida mediante validación de fachada y contenido. Las variables de estudio fueron género, logro de alimentación por pecho, y habilidades de alimentación durante el proceso de alimentación, evaluadas por 2 observadoras Se analizaron medidas de dispersión y se aplicó prueba Fisher al 5% de significancia, estableciendo la asociación de los resultados obtenidos con las variables. RESULTADOS: Se evaluaron 5 dominios: (1) Capacidad de mantenerse enfocado en la alimentación, en que el 75,3% posee un nivel desempeño deficiente y el 28,6% equitativo existiendo diferencias significativas con la variable sexo. (2) Capacidad de organizar el funcionamiento motor - oral tiene un 10,5% deficiente, un 68,8% equitativo y un 20,6% bueno. (3) Capacidad de coordinar la deglución el 95,2% presenta un rendimiento equitativo. (4) Capacidad de mantener la estabilidad fisiológica el 96,7% fue equitativo y en (5) Evaluación de la tolerancia alimentaria oral tiene un desempeño deficiente del 41,6%. CONCLUSIÓN: La escala EFS es una herra mienta que aporta información relevante para describir el proceso de alimentación oral en lactantes prematuros, permitiendo identificar las áreas de mayor dificultad que requieren tratamiento profe sional, sin embargo, esta herramienta no es suficiente por sí sola para llevar a cabo una evaluación integral del proceso de alimentación del neonato.

INTRODUCTION: The Early Feeding Skills (EFS) scale assessed the neonate's behavior before, during, and after the feeding process. OBJECTIVES: To determine the face and content validity, and to evaluate with this scale the feeding process in premature newborns comparing with relevant variables. PATIENTS AND METHOD: Premature newborns were evaluated; they were between 34 to 36 weeks of corrected age, without neurological damage or craniofacial malformations. Cross-sectional descriptive study. The data were obtained through the EFS scale, version corrected by face and content validation. The study variables were gender, breastfeeding achievement, and feeding skills during the feeding process, evaluated by two observers. Dispersion measures were analyzed, and the Fisher test was used at 5% significance, establishing the association of the obtained results with the variables. RESULTS: 5 domains were evaluated: (1) Ability to stay focused on food, in which 75.3% have a poor performance level, and 28.6% equitable, with significant differences in the sex variable. (2) Ability to organize motor- oral functioning presents 10.5% deficient, 68.8% equitable, and 20.6% good. (3) Ability to coordinate swallowing 95.2% presents an equitable performance. (4) Ability to maintain physiological stability 96.7% was equitable; and (5) Evaluation of oral food tolerance presents 41.6% of poor performance. CONCLUSION: The EFS scale is a tool that provides relevant information to describe the oral feeding process in premature infants, allowing to identify the areas of greatest difficulty that require profes sional treatment, however, this tool is not enough by itself to carry a comprehensive evaluation of the newborn feeding process.

Influence of Masticatory Behavior on Muscle Compensations During the Oral Phase of Swallowing of Smokers

Abstract Introduction Chewing and swallowing are physiologically interconnected functions, which share motor structures and supranuclear regions of the central nervous system (CNS), involving a sensorimotor synchrony. Objective To analyze the influence of masticatory behavior on muscular compensations in the oral phase of swallowing in smokers compared with nonsmokers. Methods A cross-sectional study comparing smokers and nonsmokers composed of 24 participants in each group. The aspects of food crunching, masticatory pattern, masticatory speed, atypical muscular contractions, and lip closure were analyzed during mastication. In swallowing, aspects of contraction of the orbicular and mental muscles, head movement and presence of deglutition, mastication, smoking, and of stomatognathic system of residues after swallowing were characterized. Results Statistically significant differences were identified between the study groups related to food grinding pattern, masticatory velocity, and mental contraction during swallowing. There was no significant association between masticatory function and compensations during swallowing. Conclusion Differences were observed in the pattern of chewing and swallowing in smokers compared with nonsmokers, but no influence of masticatory performance was observed in the presence of muscle compensations during the oral phase of swallowing.

Swallowing Analyses of Neonates and Infants in Breastfeeding and Bottle-feeding: Impact on Videofluoroscopy Swallow Studies

Abstract Introduction Dysphagia, when left untreated, can result in an increase in morbidity and mortality rates, especially among infants with history of life-threatening neonatal diseases. The videofluoroscopy swallowing study (VFSS) is considered the gold standard for the diagnosis of dysphagia. There are few imaging studies of infant swallowing based on videofluoroscopy, none of which were performed during breast-feeding. Objective To analyze the similarities and differences in infant swallowing function -regarding the feeding method - breast or bottle - and the impact on videofluoroscopy findings. Methods A retrospective study of 25 VFSSs of breastfeeding and bottle-feeding infants was performed. The studied variables were: oral capture and control; tongue versus mandible movement coordination; sucking pattern; mandible excursion; liquid flow; bolus retention; laryngeal penetration; tracheal aspiration; clearing of material collected in the pharynx; and gastroesophageal reflux (GER). Results The study showed a statistically significant association between nipple/areole capture; oral control; sucking pattern; mandibular excursion; liquid flow and feeding method. The velar sealing deficit, the place that trigger the pharyngeal swallow, food retention in the pharyngeal recesses, laryngeal penetration and GER were also factors associated with the feeding method. Conclusion The analysis of the swallowing characteristics of both feeding methods revealed significant differences between them, with an impact on the diagnosis in the VFSSs, especially regarding velar function.

Relationship between oral transit time and functional performance in motor neuron disease / Relação entre tempo de trânsito oral e desempenho funcional na doença do neurônio motor

ABSTRACT Oral phase swallowing impairment in motor neuron disease (MND) is caused by tongue weakness, fasciculation and atrophy, which may compromise oral transit time and total feeding time. Objective: To describe and correlate total oral transit time (TOTT) with functional performance in MND using different food consistencies. Methods: The study was conducted on 20 patients with MND, regardless of type or duration of the disease, of whom nine were excluded due to issues on the videofluoroscopic swallowing images. The remaining 11 patients (nine men and two women) ranged from 31 to 87 years of age (mean: 57 years) with scores on the Penetration Aspiration Scale ranging from ≤ 2 to ≤ 4. The Amyotrophic Lateral Sclerosis Functional Rating Scale - revised questionnaire was applied to classify individuals according to global, bulbar and bulbar/respiratory parameters. Videofluoroscopy of swallowing using 5ml of different consistencies was performed and a quantitative temporal analysis of the TOTT was carried out with the aid of specific software. Results: There was a wide variation in the TOTT within the same food consistency among MND patients. There was a correlation between the TOTT and overall functional performance for the thickened liquid consistency (r = −0.691) and between the TOTT and bulbar performance for the pureed consistency (r = −0.859). Conclusion: Total oral transit time in MND varies within the same food consistency and the longer the TOTT, regardless of food consistency, the lower the functional performance in MND.

RESUMO O comprometimento na fase oral da deglutição na doença do neurônio motor (DNM) é ocasionado por fraqueza, fasciculação e atrofia de língua, podendo comprometer o tempo de trânsito oral (TTO) e o tempo total de alimentação. Objetivo: Descrever e relacionar o tempo de trânsito oral total (TTOT) com o desempenho funcional na DNM em distintas consistências de alimento. Métodos: Participaram 20 indivíduos com DNM, independente do tipo ou tempo de doença. Foram incluídos 11 indivíduos, nove homens e duas mulheres, faixa etária de 31 a 87 anos (média de idade de 57 anos) e com Penetration Aspiration Scale (Rosenbek et al., 1996) de ≤ 2 a ≤ 4. Foram excluídos nove indivíduos por questões técnicas relacionadas às imagens videofluoroscópicas de deglutição. Aplicado o questionário Amyotrophic Lateral Sclerosis Functional Rating Scale - revised para classificação dos indivíduos de acordo com parâmetros Global, Bulbar e Bulbar/Respiratório. Realizada videofluoroscopia da deglutição com diferentes consistências de alimento no volume de cinco ml e análise quantitativa do TTOT por meio de software específico. Resultados: Houve ampla variação no TTOT dentro da mesma consistência de alimento na DNM. Houve correlação entre o TTOT e o desempenho funcional global na consistência líquida espessada (r = −0,691) e para o TTOT e o desempenho bulbar na pastosa (r = −0,859). Conclusão: O tempo de trânsito oral total na DNM varia dentro da mesma consistência de alimento e quanto mais longo o TTOT, independente da consistência do alimento, menor foi o desempenho funcional na DNM.
