장치: Low-Level Laser Therapy

Low-Level Laser Therapy (LLLT) for 5 min over eight points over the face, with the laser probe in direct contact with the superficial roots of the facial nerve. The parameters will be used wavelength of 808 nm (Polaris HP, Astar, Bielsko-Biała, Poland) and 980 nm (TheraLASER max, TheraMarkt, Germany), frequency of 1 kilohertz, the duty cycle of 80%, and energy density of 10 J/cm'. During each session, the total energy will be delivered to the patient are 1440 J per session (8 treatment points × 180 J per point; 3 W average power over a 6 cm² applicator, 60 s per point).

실험적: 갈륨 비소 다이오드 레이저

20명의 참가자는 갈륨 비소 다이오드(GaAs) 레이저(BTL-5000 레이저)를 6주 동안 연속적으로 총 18회의 치료 세션(주 3회 세션) 동안 받게 됩니다

장치: gallium arsenide diode laser (BTL-5000 laser)

gallium arsenide diode laser (BTL-5000 laser) will be used with infrared probes of 830 nm wavelength and 100 mW output power, average energy density of 10 J/em?, a frequency of 1 kilohertz, and a duty cycle of 80 %. In all cases, the laser will be in direct contact with the superficial roots of the facial nerve on the affected side and will be applied for 2 min and 5 s per point for 8 points with a total energy of 1440 J per session (8 treatment points × 180 J per point; 3 W average power over a 6 cm² applicator, 60 s per point)

활성 비교기: 고강도 레이저 치료

20명의 참가자가 고강도 레이저 치료를 펄스형 네오디뮴 도핑 옥트륨 알루미늄 가닛 레이저로 받게 되며, 총 18회의 치료 세션을 6주 연속으로(주당 세션 3회) 진행합니다.

장치: high intensity laser treatment

High intensity laser therapy treatment with pulsed neodymium doped: yttrium aluminum garnet laser. The apparatus provided the following options: pulsed emission (1,064 nm), very high peak powers (3 kW), high levels of fluency (energy density) (810-1,780 mJ/cm), brief duration (120-150 Ms), low frequency (10-40 Hertz), and a duty cycle of approximately 0.1 %. High intensity laser therapy will be applied with contact and perpendicular to the superficial roots of the facial nerve of the affected side. The time of application will be 7 s/per point with an energy density of 10 J/em'. The total energy delivered to the patient during one session will be 1440 J per session (8 treatment points × 180 J per point; 3 W average power over a 6 cm² applicator, 60 s per point). The device calculates the number of pulses, energy received for each session, and the total energy delivered to the patient during the treatment session

assessment of Compound motor action potential of facial nerve

Compound motor action potential of the facial nerve was evaluated using electroneurography. This involved measuring latency and amplitude differences between the affected and non-affected sides of the nasalis muscle. Latency was calculated from the baseline to the initial deflection, while amplitude was determined as peak-to-peak measurements, with both measures yielding Facial-nerve distal latency and CMAP amplitude at the nasalis.
