Parosmia, a condition in which the sense of smell no longer works properly, is one of the known symptoms of "Covid-19", and recent research has found that about 60% of "Covid-19" patients have been infected with parositis, and while most patients regain their sense of smell over time, some patients who suffer from the Corona virus for a long time continue to suffer from these symptoms for several months, or even years, after infection, which negatively affects their appetite for food and their quality of life in general. According to a report published on Science Tech Daily."Barosima can also affect smell perception, and some patients may experience the delusion of smelling, a condition that causes people to detect (foul or pleasant) odors that are not in their environment." To evaluate the potential treatment for patients with long-term parosmia after the coronavirus, the researchers looked at the potential benefits of CT-guided astronode blocking, part of the autonomic nervous system, which regulates autonomic processes including: The research team used astrocyte block, which involves injecting an anesthetic directly into the astrocyte node on one side of the neck to stimulate the autonomic nervous system, and this procedure takes less than 10 minutes, and does not require any anesthesia or intravenous analgesia, astronode block was used in degrees "Parosmia was previously reported as a rare disorder that occurs after brain trauma, brain surgery, stroke, viral syndromes, and with some head and neck tumors, and we were not entirely confident that the procedure would work in treating parosmia," said Dr. Zoga.For the study sample, the study was conducted on 54 patients at least six months after Twenty-six patients returned to receive a second injection given on the opposite side of the neck after a period of at least six weeks, and while the second injection was not effective in patients who did not respond to the first injection, 86% of patients who reported some improvement after the first injection reported additional improvement after the corresponding injection, and no complications or adverse events were reported.
