Photobiomodulation in the Treatment of Bell's Palsy: An Integrative Review / Fotobiomodulación en el Tratamiento de la Parálisis de Bell: una Revisión Integradora

Bell's palsy is defined as a lower motor neuron palsy that develops from a non-suppurative inflammation of the facial nerve at the stylomastoid foramen. The objective of this integrative review was to determine the effects of photobiomodulation as a therapeutic method for Bell's palsy. This qualitative study provided a broader understanding of the subject studied. Searches for articles were carried out in PubMed databases via Medline, LILACS, IBES, Scopus, Web of Science, Embase, and CENTRAL using MeSH and DeCS descriptors to determine the search terms. A total of 143 articles were found. After applying the inclusion and exclusion criteria, 7 articles were included. Therefore, it can be concluded that the application of low-level laser in the treatment of Bell's palsy is effective since the studies indicated significant and relevant improvements for the recovery of these patients when associating the laser with other types of treatments.

Se encontraron un total de 143 artículos. Después de aplicar los criterios de inclusión y exclusión, se incluyeron 7 artículos. Por tanto, se puede concluir que la aplicación de láser de baja intensidad en el tratamiento de la parálisis de Bell es eficaz debido a que los estudios indicaron mejoras significativas y relevantes para la recuperación de estos pacientes al asociar el láser a otro tipo de tratamientos.

Evaluation of Oral Mucositis Occurrence in Oncologic Patients under Antineoplastic Therapy Submitted to the Low-Level Laser Coadjuvant Therapy.

Low-level laser therapy has been widely used in treating many conditions, including oral mucositis. The purpose of this study was to evaluate the occurrence of oral mucositis in patients undergoing antineoplastic therapy submitted to preventive and therapeutic treatment with low-level laser therapy. This cross-sectional study was carried out with 51 children and adolescents of both sexes with malignant neoplasias who developed oral mucositis and underwent low-level laser therapy. Data were collected on sex, age, type and degree of neoplasia, region affected, and remission time. 64.7% of the patients were male and were between 3 and 6 years of age (39.2%). Acute lymphoid leukemia was the most frequent neoplasm (37.3%). Regarding the maximum oral mucositis, grade 2 (41.2%) was predominant, with jugal mucosa (29.9%) and tongue (17.7%) being the most affected regions. The majority of cases presented lesion remission time between 4 and 7 days (44.0%). Most patients were young, male, and diagnosed with acute lymphoid leukemia. Predominance of grade 2 oral mucositis was observed, with jugal mucosa and tongue being the most affected regions, with the majority of cases presenting lesion remission time between 4 and 7 days. Low-level laser therapy has been shown to be an essential therapy in the prevention and treatment of these lesions, since it is a non-invasive and low-cost method.
