“…Preliminary experiment also determined that 633-nm light was the most effective wavelength to increase the regeneration of rat facial nerve following crush injury among variable wavelengths (361 457 514 633 720 and 1060 nm) [49]. Most studies preferred NIR spectrum light to accelerate regeneration of facial nerve due to its capacity to penetrate in animal studies [20, 24, 25, 30-32, 34, 37] and human studies [33,35,36,50]. However, the optimal wavelength can be chosen solely on the base of its biological activity if laser irradiation can be applied directly to the injured nerve.…”

“…Therefore, major effort is required to understand whether different wavelengths exert specific biological effects and to elucidate the optimal parameters that will support the best therapeutic activity in facial nerve regeneration. Most investigations have preferred using NIR spectrum light to accelerate facial nerve regeneration because shorter wavelengths (600-700 nm) have a lesser capacity than longer wavelengths (780-950 nm) to penetrate [20,24,25,[30][31][32][33][34][35][36][37]. The red-spectrum wavelengths (600-700 nm) of PBM therapy showed satisfactory morphological and electrophysiological results in the sciatic nerve [26][27][28][29], but evidence regarding the therapeutic effects of the redspectrum light in the facial nerve is lacking.…”

We analyzed the effects of photobiomodulation (PBM) of various wavelengths on regeneration of the facial nerve using in vitro and in vivo experimental models. We assessed the antioxidative effect of PBM in geniculate ganglion neurons irradiated with a diode laser at 633 nm, 780 nm and 804 nm. Wavelengths of 633 and 780 nm but not 804 nm inhibited cell death by oxidative stress. We assessed the effects of PBM on functional and morphologic recovery in rats divided into control, facial nerve damage (FND) and FND irradiated with a 633 nm or 804 nm lasers. Injured rats treated with 633-nm light had better facial palsy scores, larger axon diameter and higher expression of Schwann cells compared with the FND group. No positive results were observed in rats irradiated at 804-nm light. These findings indicate that 633-nm PBM promotes accelerated nerve regeneration and improved functional recovery in an injured facial nerve.

“…It seems that the use of low-power lasers with active Ga-Al-As material is more widespread compared to high-power lasers [7,8,10,11] . The most effective parameters appeared to be the following: wavelength 810-930-880nm, power 100-150mW, energy density 10J/cm², contact application at eight points of the facial nerve [7,8,10,12,14,15] . The efficacy of low-power lasers with TENS currents for treating patients with Bell's palsy was also compared and the results showed that low-power lasers proved more efficient [13] .…”

Bell's palsy is reported as an acute peripheral paralysis of the facial nerve of unknown etiology. Its symptoms can range from mild to severe including a lack of wrinkles on the forehead, drooping eyelids of the affected side, uncontrolled tearing of the eye of the affected side, weakness or paralysis of the facial muscles, drooping of the mouth of the affected side and impaired taste. The aim of this review is to describe recent research data on the application of laser to patients with Bell's palsy. The PubMed and Google Scholar databases were searched for articles published between January 2015-May 2021with the following.

“…In the sixth session the protocol was changed again, in an endeavor to improve the treatment with the use of another protocol. At this time, the protocol was the same as that used in the study of Bernal Rodrigues et al (facial paralysis) [8]. A diode laser (Therapy EC DMC, São Carlos, Brazil) was used, consisting of 2 J red (660nm) and 2 J infrared (808nm) simultaneously (Table I -Phase 3).…”

Objective: The purpose of this short communication is to show that although photobiomodulation in the treatment of neurophathic oral pain after COVID-19 contagion could be an option, photobiomodulation is not a new technique. PBMT was used with different protocols and pain was assessed using VAS (visual analogue scale -0 until 10) before and after the consultation. Results: Evolution of VAS during the sessions showed a decrease in painful symptomatology as treatment was performed. Conclusion: Based on the results obtained in the present case report, we concluded that PBMT with the parameters used in this clinical case was an effective, noninvasive and a new option of treatment for neuralgia resulting from COVID-19.
