Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objective: Facial paralysis can be caused by a variety of etiological factors, complete palsy continues for two months, the chance of full recovery is reduced to zero. The aim of this study was to evaluate the effectiveness of photobiomodulation therapy (PBMT) in the in patients undergoing facial paralysis over 8 weeks.

Methods: This study was an open-label, not concurrent control study including 54 patients that underwent facial paralysis over 8 weeks. Patients were assigned to the PBMT group and control group, with 27 patients in each group. Laser treatments were applied 3 days a week after recruited. PBMT was delivered using a class IV Multi-wave Locked System that combines with a simultaneous 808 nm continuous emission and 905 nm pulse emission and the maximum peak power was 25 W. Clinical outcome measure comprised the House-Brackmann grading system, Facial Clinimetric Evaluation Scale (FaCE), Sunnybrook facial grading scale (SBFG), and electrophysiological testing, including Electroneuronography (ENoG), Electromyography (EMG) and Blink Reflex. All the measurements were collected at the first day and at the end of study. All reported P values were two-sided and were declared statistically significant when less than 0.05.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Photobiomodulation Group

Treatments were performed with MLS laser (Mphi laser, ASA Srl, Italy). MLS laser is a class IV NIR laser with two synchronized sources (laser diodes). The first one is a pulsed laser diode, emitting at 905 nm, with 25 W peak power. The second laser diode (808 nm) was operated in a continuous mode with power 1 W. Both of the laser beams were synchronized, the locked waves work within the range 1-2000 Hz.
