Surgery exposes the patient to operative risks and the risk of permanent, residual facial numbness and dysesthesias. The primary complications of surgery include permanent anesthesia over the face or the troubling dysesthetic syndrome of anesthesia dolorosa—often disabling, is occasionally worse than the original trigeminal neuralgia, and is often untreatable. For this reason, procedures with the best long-term success and the least risk of a residual facial dysesthetic syndrome are the most promising.

Many patients require pain medication even after surgery.
