Efficacy of LED Photobiomodulation for Functional and Axonal Regeneration After Facial Nerve Section-Suture

Facial nerve damage can lead to partial or total facial nerve palsy. Photobiomodulation has been reported to improve and accelerate functional recovery following peripheral nerve lesion, depending on the type of lesion and the light exposure parameters used. The aim of this study was to investigate the effects of infrared exposure on functional and axonal regeneration after section-suture of the distal branches of the facial nerve: the buccal and marginal mandibular branches and the distal pes. The animals underwent surgery and were irradiated with infrared light at 850 nm twice daily from day 1 to day 16. The recovery of facial function was then studied at both the behavioral and morphological levels. Behavioral analyses were performed by videoscoring with a high-speed camera and using various devices to assess the recovery of whisker movement on the lesioned side from day 1 to day 30. We also assessed nasal deviation toward the intact side and the ability to close the ipsilateral eyelid completely from day 1 to day 38 and from day 1 to day 50, respectively. For morphological analyses, we assessed the re-establishment of facial motoneuron labeling with Fluorogold®, an immunofluorescent retrograde marker of axonal transport injected into the vibrissae, on D10, D14 and D30. We found that whisker movements recovery was significantly faster in treated than in control mice. A complete disappearance of nasal deviation was observed at 2 weeks in infrared-treated lesioned mice and at 5 weeks in controls. Complete eyelid closure was observed 3 weeks after surgery in treated animals and 6 weeks after surgery in controls. Finally, normal fluorogold labeling of the facial nuclei complex was restored 30 days after surgery in the treated animals, but no such restoration was ever observed in control animals. In conclusion, our data show that IR treatment at a distal site has a significant positive effect on facial nerve recovery. These findings pave the way for the clinical use of infrared photobiomodulation in patients with nerve lesions.

“…The results of this review show that the use of laser therapies is a safe and effective method of treating patients with Bell's palsy. 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] . One study combined low-power laser therapy with facial expression exercises and found positive results [8] , while another proposes a protocol in which low-power laser therapy combined with expression exercises should be compared to pharmacotherapy and electrical stimulation therapy [11] . Lowpower laser therapy has also been shown to be effective in patients with diabetes as an alternative to medication due to the limitations imposed by their condition [9] .…”

“…The findings show that LAT is effective in treating patients with chronic Bell's palsy and improves their physical and social well-being. Kandakurti [11] proposed a research protocol on the efficacy of low-power laser therapy in combination with facial expression exercises and a comparison of the efficacy of electro stimulation and corticosteroid therapies. The 120 involved patients were divided into three groups.…”

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.

“…PNF is a rehabilitative technique of neuromuscular stimulation facilitation based on the activation or reactivation of proprioceptors using diagonal patterns; since most of the muscle fibers in the face run diagonally, it might be functional for the facial muscles [ 24 , 28 , 29 , 30 ]. In the last years, a high interest has been growing regarding the use of instrumental physical therapies, such as lower-level laser therapy and electrical stimulation, in improving facial muscle function in patients with facial palsy [ 30 , 31 , 32 , 33 ]. At the same time, short-wave diathermy (SWD) is considered as an innovative therapeutical option to reduce pain and improve HRQoL in musculoskeletal disorders [ 33 ].…”

There is a lack of data on patient and diagnostic factors for prognostication of complete recovery in patients with peripheral facial palsy. Thus, the aim of this study was to evaluate the role of a telerehabilitave enhancement through the description of a case report with the use of short-wave diathermy and neuromuscular electrical stimulation combined to facial proprioceptive neuromuscular facilitation (PNF) rehabilitation in unrecovered facial palsy, in a COVID-19 pandemic scenario describing a paradigmatic telerehabilitation report. A 43-year-old woman underwent a facial rehabilitation plan consisting of a synergistic treatment with facial PNF rehabilitation, short-wave diathermy, and neuromuscular electrical stimulation (12 sessions lasting 45 min, three sessions/week for 4 weeks). Concerning the surface electromyography evaluation of frontal and orbicularis oris muscles, the calculated ratio between amplitude of the palsy side and normal side showed an improvement in terms of movement symmetry. At the end of the outpatient treatment, a daily telerehabilitation protocol with video and teleconsultation was provided, showing a further improvement in the functioning of a woman suffering from unresolved facial paralysis. Therefore, an adequate telerehabilitation follow-up seems to play a fundamental role in the management of patients with facial palsy.
