Bell's Palsy With a Duration of Greater Than 8 Weeks Treated With Multiwave Locked System Intervention
Sponsor: Beijing Tongren Hospital
Summary
OBJECTIVE: To determine whether photobiomodulation therapy by class IV Multiwave Locked System laser treatment could relieve symptoms in patients with Bell's palsy with a duration of greater than 8 weeks. METHODS AND METHODS: This randomized controlled trial from May 2021 to April 2023. Patients were eligible who had Bell's palsy with a duration of greater than 8 weeks on out-patient department of otorhinolaryngology in Beijing Tongren Hospital. The photobiomodulation group received class IV Multiwave Locked System laser treatment for 3 times per weeks, a total of 6 months. The control group received the same Multiwave Locked System treatment procedure except the laser parameter. The primary outcome measures comprised House-Brackmann facial nerve grading system, Sunnybrook facial grading system, Facial Clinimetric Evaluation Scale. Secondary outcome measures comprised Electroneurography, Electromyography, and the Blink Reflex.

Multiwave Locked System
Multiwave Locked System laser is a class IV NIR laser with two synchronized sources (905 nm with 75 W peak power, pulsed mode; 808 nm with power 1 W, continuous mode). Both laser beams were synchronized, the locked waves work with the range 1-2000 Hz.
