Abstract

Purpose: To analyze the effects of electrical stimulation on the salivary flow of head and neck cancer patients with radiotherapy-induced hyposalivation. Research strategies: Searches were made in the Medline (via Pubmed), Cochrane Library, Scopus and Lilacs databases. Selection criteria: Selection included clinical trials that evaluated salivary flow objectively, published in the last 10 years in either Portuguese, English or Spanish. Data analysis: The PEDro scale was used for the methodological evaluation of the studies. Results: The search strategy resulted in 21 publications, 17 of which were excluded, hence there were 4 articles left. The included studies had a total of 212 participants, all of whom had an increase in salivary flow, both through the electroacupuncture method and direct application on the salivary glands. The score obtained through the PEDRo scale was low, evidencing questionable methodological quality and risk of bias. Conclusion: The included studies demonstrate the clinical potential of TENS to increase the salivary flow of head and neck cancer patients treated with RT.

Resumo

Objetivo: Analisar os efeitos da eletroestimulação sobre o fluxo salivar de pacientes com hipossalivação induzida por radioterapia em região de cabeça e pescoço. Estratégia de pesquisa: Utilizaram-se as bases de dados Medline (via Pubmed), Cochrane Library, Scopus e Lilacs. Critérios de seleção: Foram selecionados os ensaios clínicos que avaliaram objetivamente o fluxo salivar, publicados nos últimos 10 anos em português, inglês ou espanhol. Análise dos dados: Para avaliação metodológica dos estudos, foi utilizada a escala PEDro. Resultados: A estratégia de busca resultou em 21 publicações, sendo que 17 foram excluídas, selecionando-se assim 4 artigos. Os estudos incluídos contaram com um total de 212 participantes, sendo que todos demonstraram aumento do fluxo salivar, tanto por meio do método de eletroacupuntura quanto pela estimulação aplicada diretamente sobre as glândulas salivares. A pontuação obtida por meio da escala PEDro foi baixa, evidenciando qualidade metodológica baixa e com consideráveis riscos de viés. Conclusão: os estudos incluídos demonstram o potencial clínico da TENS no aumento do fluxo salivar de pacientes com câncer de cabeça e pescoço tratados com RT
