Summary

The aim of this study is to assess whether the use of a therapy combining olfactory training, corticoids, and phototherapy improves the PROMS compared to the use of olfactory training and corticosteroids only. To accomplish this goal the study will consist of 40 participants. The participants must present olfactory dysfunction for at least 4 weeks after a coronavirus-19 infection. Furthermore, to be eligible each participant will need a polymerase chain reaction test with positive results for coronavirus-19.

Interventions

COMBINATION_PRODUCT

Phototherapy

Prior to the beginning of the procedure the patient will be administered a nasal decongestant. Second to this, the patient will be advised to blow his/her nose. This step allows the physician a better view and allows the light exposure to reach the majority of the nasal mucosa(9). To start the intervention the physician will introduce the phototherapy device inside the patient's nasal cavity as the patient sits in an upright condition. As the procedure is ongoing the physician will slightly rotate the device in order to minimize dryness and to irradiate all the nasal cavity. After the intervention the patient will be administered an emollient/moisturizing drug to further hydrate the nasal mucosa(9). The intervention will have a crescent duration, the first one will be only two minutes and the following ones will increase 15 seconds each until a plateau is reached at 3 minutes in the 5th intervention.

OT+Corticosteroids

Patients that present loss of smell 4 weeks after their coronavirus-19 infection and that have had a real-time polymerase chain reaction (reverse transcriptase polymerase chain reaction )and both oral corticosteroids (prednisone 40mg) and olfactory training will be applied, in the intervals of daily for 10 days and daily for the duration of the study respectively.
