The present study aimed to report a series of cases in which three protocols of intranasal photobiomodulation therapy (PBMT) were used for COVID-19-related olfactory dysfunction. Irrespective of the PBMT protocol, olfaction recovery was noted in all cases but with varying degrees of improvement. Although intranasal PBMT seems to be a promising therapeutic modality, more research is needed to better define effectiveness.pdfenArtigos de PeriódicosLuís Eduardo Silva SoaresMilena Miranda Goulart GuiradoGiuseppina BerlingieriMarcia Christina Camargo Hernandes RamiresLuciana Aparecida de Oliveira P.
