EFICIÊNCIA DA LASER DE BAIXA POTÊNCIA NA PARALISIA DE BELL: UMA REVISÃO LITERÁRIA.

Abstract

Peripheral facial palsy (PFP), also known as Bell's palsy (BP), is characterized by unilateral facial immobility. Its etiology is considered idiopathic, and it is reported with weakness, taste abnormalities, paresthesia in the cheek on the affected side, hyperacusis, and pain behind the ear. In this context, this study seeks to understand the effects of laser therapy on the symptoms of Bell's palsy. This study comprises a systematic literature review. Data was obtained through scientific research sources recognized for their reliability, such as SCIELO, PUBMED, REASE, and Google Scholar. Studies from 2020 to 2025 were selected; of the articles found, only 15 met the inclusion criteria for this review, including 12 case studies and 3 randomized clinical trials. Laser therapy is a physiotherapeutic resource also used in other areas of health and has demonstrated effectiveness in its application for patients with Bell's palsy, improving motor and functional symptoms such as the recovery of facial muscle movements, normalization of taste, and reflexes such as opening and closing the eyes.
