Gasserian Ganglion Block - Complications
What Possible Side Effects Might I See?
In general, the most frequent complication includes, facial swelling, bruising because of the proximity of blood vessels to the gasserian ganglion. This should be treated with ice and elevation, should it occur. In addition, other nerves are adjacent to the gasserian ganglion and can, in very rare circumstances, develop weakness from the local anesthetic medication. In general, this would be noticed in the recovery room. However, if you had difficulty with breathing or swallowing following the procedure, we would want you to inform one of the recovery room nurses or physicians.
Sometimes, despite the use of an X-ray machine, we are unable to place the medication in the appropriate space because of technical difficulty. Finally, while most patients get pain relief, in rare instances, sometimes there is an aggravation of the current pain symptoms. This is likely secondary to the facial swelling or bruising as stated, and is likely to last for several days.
