The use of stereotactically guided radiation for the treatment of trigeminal neuralgia. Stereotactic describes a method in neurosurgery and neurological research for locating points within the brain using an external, three-dimensional frame of reference usually based on a map/atlas (defined coordinate system).

Procedure

Stereotactic radiosurgery is performed as an outpatient procedure. The procedure is noninvasive and there is a low complication rate. Magnetic resonance imaging is used to identify the trigeminal nerve. A single radiation beam is aimed at the appropriate target. Over a period of time and as a result of exposure to the radiation the slow formation of a lesion in the nerve interrupts transmission of pain signals to the brain.

Post-procedure

An increase in facial skin sensation, such as burning, prickling, itching, or tingling, with no apparent physical cause and a decrease in sensation.

Risk of Radiosurgery

Delayed pain relief.
