Abstract
Objective: Painful post-traumatic trigeminal neuropathy (PTTN) is a clinical pain syndrome that occurs due to injuries to the peripheral branches of the trigeminal nerve and is characterized by a deep burning pain and accompanied by positive and negative neurological signs. In patients with recalcitrant PTTN, the sympathetic nervous system is a potential therapeutic target. The aim of this study was to investigate the therapeutic response of PTTN patients to pulsed radiofrequency treatment (PRF) of the superior cervical sympathetic ganglion (SCG).Methods: Thirty-five patients with PTTN who had a history of severe disabling facial neuropathic pain underwent PRF of the SCG under a new lateral fluoroscopic approach.Results: The patients' pain intensity post-PRF was 3.94 (± 3.11), compared with 8.82 (± 1.27) pre-PRF (p < .001).Conclusion: PRF of the SCG could be an effective method to treat chronic PTTN.
