About

Idiopathic facial nerve palsy (Bell's palsy) is caused by damage to the facial nerve at any site of the peripheral branches after the facial nucleus.Stellate ganglion block is inteneded to increase blood flow and promotes nerve regeneration.

Full description

the conventional systemic corticosteroid treatment for acute peripheral facial nerve palsy in patients can induce hyperglycemia, and an alternative local therapy may be necessary and some time may ve ineffective.

Our purpose in this study is to evaluate therapeutic effects of stellate ganglion block (SGB) on idiopathic persistant facial nerve palsy.

Stellate ganglion block

Active Comparator group

Description:

Patients underwent a stellate-ganglion block at the anterolateral aspect of the C6 vertebra. After local analgesia (lidocaine 2%), a 22-gauge Quincke needle was placed in the anterolateral aspect of the C6 vertebral body. When the needle contacted the bone, it was drawn back 1 mm. 5 mL of 0·5% ropivacaine was subsequently injected next to the stellate ganglion to produce a sympathetic block.The effect of the stellate-ganglion block on the sympathetic nervous system was confirmed by the presence of Horner's syndrome (ie, facial anhydrosis, enophthalmos, ptosis, swelling of the lower eyelid, miosis, and blood-shot conjunctiva), and an increase in the temperature of the right hand of at least 2°F from baseline.
