Efeito do laser de baixa intensidade para tratamento do zumbido: revisão integrativa

Abstract

Introduction: Humans can, throughout life, be affected by innumerable dysfunc-tions that bring temporary or permanent symptoms, which directly impact their quality of life. Among these problems, there is tinnitus, which can be defined as a persis-tent sound without the presence of an external sound source (MORES et al., 2019). Its treatment has several modalities, including pharmacotherapy, physiother-apy, psychotherapy, surgical interventions and individual hearing aid adaptation (MONTAZERI et al., 2017; Rocha, 2018). More recently, new approaches have been proposed for its treatment. One is the use of LASER therapy to induce blood flow improvement and activate the mitochondrial process (OKHOVAT et al., 2011). Ob-jective: To identify the effectiveness of low-level LASER therapy (LLLT) on tinni-tus. Methodology: Integrative review study, with the guiding question: "Are there studies that prove the effectiveness of low-level LASER therapy on the treatment of tinnitus?". Ten national and international publications were selected to compose the study. Conclusion: Based on the research analyzed in this integrative review, it is not possible to state that the application of LLLT produces a definitive effect in the treatment of tinnitus. There is a positive trend regarding its use. There is a need to validate protocols with defined methodology and parameters. It is a safe, non-invasive procedure, with no side effects when done at low level.
