Effect of Stellate Ganglion Block Combined With Facial Nerve Block on the Treatment of Idiopathic Facial Paralysis

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.

Operator touching the location of the mastoid, in the external auditory canal just below the front of the mastoid vertical needling.When touch the surface of the mastoid,adjust the needle across the front of the mastoid then slow needling about 1cm.The pin located below the stylomastoid foramen, and then injected drugs 5mL ( mecobalamin injection 1mg；lidocaine 60mg； dexamethasone 10mg )
