CAN THE LOW-LEVEL LASER THERAPY BENEFITS THE CONVENTIONAL TREATMENT TO THE BELL’S PALSY? REPORT OF A SUCCESSFUL CASE

Bell's Palsy (BP) is a peripheral facial nerve disorder that causes unilateral facial muscle paralysis. As a complementary effect to physiotherapy exercises, low-level laser therapy (LLLT) is considered a conservative treatment option due to its positive impact on cell and tissue recovery. This study aims to report a successful case of LLLT in treating BP in a child, discussing its benefits in optimizing the recovery process. A 7-year-old girl, without special healthcare needs, was brought to the medical office with the complaint of a "paralyzed face," and was diagnosed with BP. The treatment involved physiotherapy (twice weekly) combined with laser therapy. Fifteen sessions of photobiomodulation were conducted using a low-level laser (Laser Duo, Mmoptics, energy of 780mJ, 100mW). The applications were on alternate days for 10 seconds at marked points. Improvement in facial expression and symmetry was observed, with complete restoration of normalcy after one month, suggesting that LLLT could be a promising alternative to conventional BP treatment.
