Interventional procedures for facial pain.
Interventional pain procedures are critical in the diagnosis and management of a variety of facial pain conditions. Trigeminal neuralgia (TN) is the most frequent diagnosis for facial pain, with a reported prevalence 10 times greater than persistent idiopathic facial pain (PIFP). Although pharmacological treatments and psychological interventions benefit many patients with these diagnoses, the pain remains disabling for a significant portion of others. Percutaneous interventions targeting the gasserian ganglion and its branches have proven effective in the management of TN, while there is also supportive evidence for treating the sphenopalatine ganglion in PIFP.
