Early in the pandemic, when people with COVID-19 began reporting that they lost their sense of smell. Various studies suggested loss of smell as a symptom of viral infections.
According to a 2022 survey,about 15% of people who experienced smell loss from COVID-19 continued to have problems six months later.Many who report loss of smell also report loss of taste because smell is such a major component of how we experience food.
A new treatment for long-term, COVID-19-related smell loss using injections of platelet-rich plasma derived from a patient's own blood. Platelet-rich plasma is a concentrated form of plasma, the liquid portion of blood, with blood cells and other blood components removed. It's rich in platelets and, most importantly, growth factors — compounds known to help regenerate tissue. Platelet-rich plasma has been purported to treat mild arthritis when injected into joints, reduce wrinkles when used on the face, and even regrow hair when injected into the scalp.
Study showed that platelet-rich plasma injections were as effective as surgery in treating carpal tunnel syndrome, which is caused by compressing and injuring a nerve in the wrist.COVID-19-related smell loss also was a neurological problem, in which long-term effects of the virus prevent nerves deep in the nasal cavity from regenerating correctly. These nerves connect to the brain and normally regenerate every three to four months.
Submucosal injections of PRP into the olfactory cleft were well tolerated without significant adverse effects.However, it would be important to counsel potential patients that subjective improvement following PRP therapy can vary by individual. Larger studies are required to better determine optimal candidacy, further assess efficacy, and standardize protocols.
Therefore platelet rich plasma injections can be used as a boon to cure COVID related smell loss.
