Gasserian ganglion block is a procedure that involves injecting an anesthetic around the gasserian ganglion, a nerve cluster that transmits sensation from the face to the brain. This block is performed to relieve severe facial pain, particularly from trigeminal neuralgia. It is a minimally invasive option that provides temporary pain relief. The procedure involves imaging guidance to insert a needle near the ganglion and administer the anesthetic. Potential indications include severe pain that is unresponsive to medications or other treatment options. Contraindications and complications are rare but may include bleeding or infection. The effectiveness and duration of the block vary, but it typically provides significant pain relief for several months.
