Fotobiomodulação no tratamento de mucosite oral induzida por terapia antineoplásica: relato de caso

Abstract

Introduction: Oral mucositis (OM) is a common complication during antineoplastic treatment and among its signs and symptoms, erythema, ulceration, hemorrhage, edema and pain stand out. Low-level laser therapy is an alternative that minimizes the deleterious effects resulting from antineoplastic therapies and acts on the limitations imposed by the global condition, thus allowing the maintenance of quality of life. The present work aims to report the case of an oncological patient who presented oral mucositis as a result of antineoplastic treatment and to emphasize the use of photobiomodulation in the treatment of these lesions. Case report: Was realized a patient undergoing radiotherapy treatment for head and neck cancer was monitored, who underwent photobiomodulation in the treatment of oral mucositis (OM) lesions, using a low-power laser device (Laser Duo MMOptics, São Carlos, SP, Brazil Power: 0.1 W (100 mW) and spot area: 0.03 cm2). With the use of low-level laser, the decrease in the severity of injuries and pain was remarkable, which contributed to the reduction of dysphagia, providing an improvement in the systemic condition during treatment. Discussion: The results found are in agreement with other authors who reported that laser therapy has been shown to be a very efficient and promising method in the treatment of oral mucositis, since it reduces pain and accelerates the healing process of the lesions. Conclusion: According to the findings of this study, it is concluded that the therapeutic use of low-level laser was able to promote the healing of OM lesions and reduce symptoms, contributing to the improvement of feeding and with that the improvement general health condition patient's, which contributed to the continuity of the antineoplastic treatment, thus enabling its finalization.
