A team of researchers has managed to restore the sense of smell for the first time to a small group of patients with persistent Covid, through a procedure “minimally invasive” of ten minutes guided by image.
The new method, which involves an injection, will be presented next week at the annual meeting of the Radiological Society of North America (RSNA).
Parosmia, a condition in which the sense of smell stops working correctly, it is a symptom of Covid-19.
About 60% of patients has suffered it and although the majority recovered their sense of smell, in some patients with persistent Covid, the problem persists for months, or even years, which has a negative impact on their appetite and quality of life.
“Post-covid parosmia is common and increasingly recognized.” “Patients can develop aversion to food and drinks that they previously enjoyed,” explains the lead author of the study, Adam C. Zoga, professor at Jefferson Health in Philadelphia, Pennsylvania.
