Abstract

Trigeminal neuralgia is characterized by recurrent episodes of intense lancinating pain affecting the face localized to the sensory supply areas of the trigeminal nerve. There is a lack of certainty regarding the etiology and pathophysiology of trigeminal neuralgia. The diagnosis of idiopathic typical trigeminal neuralgia requires the absence of clinically evident neurological deficit. Treatment must be individualized to each patient. Various trigeminal neural blockades can be options when medical therapy fails to relieve pain. Neural blockades include peripheral nerve branch blocks and intracranial nerve root or ganglion blocks such as RF thermocoagulation, percutaneous balloon compression and glycerol rhizolysis. Neural blockade with local anesthetics produces temporary effects, but neural blockade with neurolytics like alcohol lasts longer, around one or two years. They are very useful for patients with poor general condition or high risk. RF rhizotomy and balloon compression of trigeminal ganglion are relatively more invasive treatment options, but have more cost effectiveness with less serious complications compared to other surgical procedures. The continuous improvement of neural block techniques is necessary for better treatment of trigeminal neuralgia.
