Reviving Sense of Smell in Long COVID Patients: Promising Procedures and Treatments

A minimally invasive procedure called computed tomography (CT)-guided stellate ganglion block (SGB) has shown promise in restoring the impaired sense of smell in COVID-19 survivors suffering from long-term parosmia. In a study conducted at Jefferson Health in Philadelphia, researchers performed SGB on 54 patients with parosmia, resulting in 59% of patients reporting symptom relief within one week. The procedure, which takes less than 10 minutes and does not require sedation, has been successful in treating various conditions. The researchers believe that SGB, guided by CT, could be an efficient and effective treatment for post-COVID parosmia.
