Stellate Gnaglion Block in Refractory Bell's Palsy

Stellate Gnaglion Block Versus Conventional Therapey in Refractory Bell's Palsy; A Rondomized Single Blind Clinical Trial

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.

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.
