Use of Cryoneurolysis Therapy for the Management of Idiopathic Trigeminal Neuralgia

Introduction Trigeminal neuralgia is a debilitating facial pain condition characterized by recurrent, electric shock-like episodes within the trigeminal nerve distribution. While first-line treatment involves pharmacologic therapy, treatment options are limited for patients who are refractory or poor surgical candidates. Case Presentation We present a 75-year-old female with long-standing idiopathic trigeminal neuralgia refractory to combination anticonvulsant therapy and nerve block, with notable medication-related side effects. Management and Outcomes The patient underwent percutaneous cryoneurolysis targeting the maxillary (V2) and mandibular (V3) divisions of the trigeminal nerve under fluoroscopic guidance. She experienced immediate pain reduction and complete symptom resolution at a one-month follow-up with no complications. Conclusion This case highlights percutaneous cryoneurolysis as a minimally invasive treatment option for selected patients with refractory trigeminal neuralgia who are not candidates for open surgical intervention.
