Uso da fotobiomodulação a laser no tratamento de AGEUSIA e ANOSMIA: relato de caso

Abstract

Therapeutic approaches to combat cancer aim to eliminate or control the disordered proliferation of malignant cells, which can result in smell and taste disorders as side effects. The loss of these senses can lead to disorders in the quality of life of patients, such as malnutrition, impacts on their perception of personal hygiene and sensory hazards. Laser photobiomodulation stimulates cell regeneration, reduces inflammation and improves the function of taste buds and olfactory epithelium, and is studied as a promising approach for the recovery of smell and taste. The objective of this study is to evaluate the action of laser photobiomodulation on ageusia and anosmia, through a case report. Patient J.R.F., a 75-year- old male, of mixed race, undergoing chemotherapy, attended the Laser Clinic of the Department of Dentistry of the Federal University of Sergipe (DOD-UFS), having been referred by the Oncology Department of the University Hospital, after reporting that he was “losing his sense of taste”. A protocol of 15 laser photobiomodulation sessions was used, using the Laser Duo (MMOptics, São Carlos, SP, Brazil) with Power (P) = 100 mW, spot area: 0,03 cm² and infrared wavelength (808 nm), applied twice a week, associated with home exercises through stimuli for smell and taste. In the present case report, an improvement in the clinical picture of ageusia and anosmia was observed after fifteen sessions of laser photobiomodulation, contributing to a better quality of life for the patient.
