Abstract Ramsay-Hunt syndrome is an infectious disease associated with the varicella-zoster virus, and peripheral facial palsy is often one of its clinical manifestations. This case report describes a patient diagnosed with Ramsay-Hunt syndrome who developed peripheral facial palsy and was treated by photobiomodulation therapy. A 26-year-old woman developed a lack of facial mobility on the right side, asymmetry, otalgia, dysgeusia, and dry eyes, leading to the diagnosis of Ramsay-Hunt syndrome. Her peripheral facial palsy was classified as moderately severe according to the House-Brackmann scale. Acyclovir, prednisone, and physiotherapy sessions were prescribed to manage peripheral facial palsy. In the absence of a clinical response to the proposed therapies, photobiomodulation therapy was employed using the parameters: 780 nm, 100 mW, 3 J/point, and 30.48 J/cm2. After five sessions of photobiomodulation therapy, complete recovery of facial movement was observed. Photobiomodulation therapy treated peripheral facial palsy effectively, allowing a fast recovery and avoiding irreversible sequelae in a patient with Ramsay-Hunt syndrome.

Resumo A síndrome de Ramsay Hunt é uma doença infeciosa associada ao vírus varicela zoster e a paralisia facial periférica é frequentemente uma das suas manifestações clínicas. Este relato de caso descreve uma paciente com diagnóstico de síndrome de Ramsay Hunt que desenvolveu paralisia facial periférica e foi tratada com fotobiomodulação. Uma mulher de 26 anos desenvolveu falta de mobilidade facial do lado direito, assimetria, otalgia, disgeusia e olhos secos, levando ao diagnóstico de síndrome de Ramsay Hunt. A paralisia facial periférica foi classificada como moderadamente grave de acordo com a escala de House Brackmann. Foram prescritos aciclovir e prednisona, além de sessões de fisioterapia para manipulação da paralisia facial periférica. Na ausência de resposta clínica às terapias propostas, foi empregada fotobiomodulação nos parâmetros: 780 nm, 100 mW, 3 J/ponto e 30,48 J/cm2. Após cinco sessões de fotobiomodulação, foi observada uma recuperação completa do movimento facial. A fotobiomodulação foi eficaz no tratamento da paralisia facial periférica, permitindo uma rápida recuperação e evitando sequelas irreversíveis numa paciente com síndrome de Ramsay Hunt.

Abstract: The objective of this study is to present a tool to help understand how variables associated with oral cancer prevention relate to each other in a social network. A search of the Scopus database was performed using terms related to oral cancer and prevention from 2000 to 2020. The keywords were used as nodes and were analyzed using NodeXL, which produced the network graphic analysis. From the 1004 publications available, 4038 different keywords were obtained and then grouped into 75 constructs based on conceptual similarity. The most influential nodes were risk factors, comorbidities, epidemiology, and treatment. However, topics such as technology, telemedicine, self-examination, and diagnostic delay remain far removed from central relations. Network analysis enabled us to observe the bias of biological and basic science in the field and identify a need for studies concerning primary prevention, behavioral interventions, and inequalities in oral cancer.
