A new minimally invasive procedure may restore COVID-related impaired sense of smell, suggests a small study to be presented at next week’s Radiological Society of North America (RSNA) annual meeting in Chicago.

Researchers at Jefferson Health in Philadelphia performed computed tomography (CT)-guided stellate ganglion block (SGB) in 54 patients who had long-term parosmia (impaired sense of smell that can lead to a distaste for once-like foods and drinks). The average patient age was 46 years, and 74% were women.
