A Brazilian multicenter pilot case series on the efficacy of photobiomodulation therapy for COVID-19-related taste dysfunction.

Background And Aim: Among the most common symptoms of COVID-19 is taste dysfunction, which has a ranging clinical presentation. As well as its pathophysiology remains to be unclear, there is not enough information about the efficacy and safety of the available treatments. This study aims to report a series of cases using PBMT for the management of COVID-19-related taste impairment.

Intranasal photobiomodulation therapy for COVID-19-related olfactory dysfunction: A Brazilian multicenter case series.

Olfactory dysfunction is commonly seen in COVID-19 patients; however, little is known about the pathophysiology and management. 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.

Photobiomodulation therapy and antimicrobial photodynamic therapy for orofacial lesions in patients with COVID-19: A case series.

Oral lesions related to the novel Coronavirus Disease 2019 (COVID-19) have been increasingly described; however, clinical and epidemiological information is still scant. Although a diversity of therapeutic strategies for the management of these lesions are present in the literature, one can note a lack of standardization and doubtful effectiveness. Thus, the present study aimed to report a series of cases in which a combination of antimicrobial photodynamic therapy (aPDT) and photobiomodulation therapy (PBMT) was used for orofacial lesions in patients suffering from COVID-19.
