Stellate Ganglion Block for Treating Post-COVID Impairment of Taste and Smell.

Abstract

Background: The loss of smell and taste are some of the chronic complications that have impacted and continue to impact patients who suffered a COVID-19 infection. Impairment of smell and taste have significant impact on patients' lives. Current treatment modalities are very limited.

Case report: We present a 40-year-old patient who completely lost smell and taste following a COVID-19 infection. The patient was treated with bilateral stellate ganglion blocks (SGBs) where each side was blocked at separate visits. At the 6-month follow-up, taste and smell both improved by 90%.

Conclusions: SGBs should be considered as an option in treating loss of smell and taste in patients who suffer this complication as a result of COVID-19 infection.
