The effect of stellate ganglion block on peripheral facial palsy

With the use of electroneuronography and palsy score

Abstract

The purpose of this report is to evaluate the effect of stellate ganglion block (SBG) on the peripheral facial palsy, using electroneuronography (ENoG).
In 34 cases of facial palsy who were treated with SBG within 2 weeks after the onset, ENoG and palsy scores were examined simultaneously.
The patients, of whom minimal ENoG value was above 40%, compared with the intact side, were recovered completely, but the patients with under 5% of that, still remained the impaired situation.
