Limits on quality of life in communication after total laryngectomy

Introduction: Among people affected by cancer, the impairment of quality of life of people affected by cancer can cause have devastating effects. The self-image of patients after post-laryngectomyzed patients may be find themselves compromised, affecting the quality of life in this population. Objective: To characterize quality of life in related to communication in people who have undergone went total laryngectomy surgery. Methods: This is an observational study, with a cross-sectional and descriptive series. Design of series study. The sample were comprised 15 patients interviewed the period from January to February of 2011. We used the Quality Protocol for Life Communication in Post-laryngectomy adapted from Bertocello (2004); which this questionnaire contains 55 questions. The protocol was organized from the nature of using responses classified as positive and negative aspects, proposals in with respect to five 5 communication domains: family relationships, social relationships, personal analysis; morphofunctional aspect, and use of writing. To promote and guarantee the autonomy of the respondents, was examiners made use of used assistive technology with the Visual Response Scale. Results: The responses that total laryngectomy compromises the quality of life in communication amounted to 463 occurrences (65.7%), and that who responses suggesting good quality of life were represented with amounted to 242 occurrences (34.3%), from a total of 705 occurrencesresponses. From Among the five 5 Communication domains, four 4 had percentages of above 63% for occurrences of negative content for impact on communication. Appearance Morphofunctional appearance gave the had the highest percentage of negative content, amounting to 77.3% of cases. Conclusions: The results showed important limitations of a personal and social nature due to poor communication with their peers. Thus, there is a need for multidisciplinary interventions that aim to minimize the entrapment of...

Electrical activity of the masseter during swallowing after total laryngectomy / Atividade elétrica do masseter durante a deglutição após laringectomia total

Total laryngectomy is a surgical procedure that can change swallowing biomechanics, including muscle activity of the masseter; this muscle stabilizes the mandible. AIM: To characterize the electrical activity of the masseter muscle during swallowing after total laryngectomy. Series study. MATERIAL AND METHODS: An electromyographic evaluation of swallowing was carried out; three different volumes of water (14.5ml, 20ml and 100ml) were swallowed, and there was a rest condition. The electromyographic signal was normalized by Maximum Resisted Voluntary Activity - considered as 100 percent of electrical activity of muscles. All other values were calculated as a percentage of this parameter. RESULTS: There is moderate electrical activity of the masseter during swallowing with higher averages on the left. There was no difference between swallowing 14.5ml or 20ml. Natural swallowing of 100ml had the lowest average. Electromyographic signals were recorded at rest on both sides, indicating the existence of electric activity in this situation. CONCLUSION: Patients submitted to total laryngectomy present electrical activity of the masseter muscles during swallowing and at rest. This activity is influenced by the volume of swallowed liquid, and showed significant differences among the tasks. Clinical Trials: NCT01095289.

A laringectomia total é um procedimento cirúrgico que pode promover alterações na biomecânica da deglutição, inclusive na atividade do músculo masseter, que atua promovendo estabilidade mandibular. OBJETIVO: Caracterizar a atividade elétrica muscular do músculo masseter durante a deglutição em laringectomizados totais. Estudo de série. MATERIAL E MÉTODO: A avaliação eletromiográfica foi realizada com a deglutição de três diferentes volumes de água (14,5 ml, 20 ml e 100 ml), e na situação de repouso. O sinal foi normalizado pela máxima atividade voluntária resistida (MAVR), considerada como 100 por cento de atividade elétrica muscular. Todos os outros valores foram calculados como percentagem da MAVR. RESULTADO: Existe moderada atividade elétrica muscular do masseter durante a deglutição, com maiores médias no lado esquerdo. Não há diferenças entre as deglutições de 14,5 ml e 20 ml. A deglutição de 100 ml apresentou as menores médias nas tarefas de deglutição. Houve presença de sinais eletromiográficos no repouso bilateralmente, indicando a existência de atividade elétrica nessa situação. CONCLUSÃO: Laringectomizados totais apresentam atividade elétrica do músculo masseter durante a deglutição e no repouso. Essa atividade sofre influência do volume de líquido deglutido, apresentando diferença significativa entre as tarefas solicitadas. Clinical Trials: NCT01095289.

Atividade elétrica do músculo masseter durante a deglutição de líquido em adultos jovens / Electrical activity of masseter muscle in young adults during swallowing of liquid

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.
