ABSTRACT
Background: Paralysis of the facial muscles produces functional and aesthetic disturbance that has a negative impact for the patient's quality of life. Objective: To evaluate the effects of a photobiomodulation (PBM) with low-level laser (LLL) on the treatment of a patient with 8 years of facial paralysis. Methods: PBM with two different wavelengths of LLL (660 and 808 nm), applied only on the affected side, three times a week for 8 consecutive weeks. Evaluations were performed before starting treatments, after the 12th session of treatment and after the 24th session, using the House-Brackmann scale and electroneuromyography. Results: The House-Brackmann and electroneuromyography tests showed improvements in the movement of the facial muscles when tested in the middle and at the end of the treatment with LLL. Conclusions: PBM with LLL at the wavelength of 660 and 808 nm with the parameters used in this case report was an effective and noninvasive treatment for facial paralysis in this long-standing, chronic case of 8 years.

Background: Radiotherapy is one of the treatments for cancer, which leads to many oral side effects that affect the quality of life of the patient; among them, trismus is considered. Objective: Considering the various therapies to treat this collateral effect of radiotherapy, photobiomodulation (PBM) with low-level laser is a contemporary alternative. Methods: In this article, an all-clinical case report is presented in which the patient was given trismus after radiotherapy and PBM with low-level laser. The measurement of the buccal opening was evaluated in each treatment session with a digital caliper, and the pain was evaluated through the visual analog scale (VAS). Results: The efficacy of the PBM protocol on the trismus after radiotherapy was evidenced by the decrease of pain and increase of the buccal opening. Conclusions: The use of PBM with low-level laser is an option for the treatment of trimus after radiotherapy.

BACKGROUND: Several photobiomodulation (PBM) protocols with low-power lasers have been reported for pain control and tissue repair in the postoperative period of oral surgeries. However, there are still no reports of a protocol for bichectomy surgeries' postoperative period. OBJECTIVE: This article presents six reports of clinical cases in which bichectomy surgery was performed. METHODS: In the postoperative period, three patients were submitted to PBM with low-power lasers, while three patients did not receive it. Facial edema was evaluated using a millimeter tape. Pain was determined using the visual analog scale. RESULTS: Data of each clinical case were evaluated in a descriptive way and compared. CONCLUSIONS: The efficacy of the PBM protocol on the postoperative period of bichectomy surgeries was evidenced by the decrease of edema and pain.
