Hemifacial spasm: a new technique of facial nerve blockade

A new technique of facial nerve blockade using a special needle and a nerve stimulator was introduced. The results in patients suffering from hemifacial spasm are reported. This technique reduced the difficulties in identifying the facial nerve and decreased the suffering associated with the conventional way of creating these blocks. The technique described may also allow titration of neurolytic agent which may produce complete relief from spasm with much less likelihood of facial paralysis after the nerve blockade.
