Introduction:
Painful tic convulsif syndrome is ipsilateral facial trigeminal neuralgia combined with hemifacial spasm, which is relatively rare in the clinic. Microvascular decompression is currently considered to be an effective treatment. We report extracranial radiofrequency treatment of painful tic convulsif syndrome under local anesthesia, a technique which provides a safer and more economical treatment for this kind of patient.
Case Presentation:
We report a case of painful tic convulsif syndrome which was treated with extracranial radiofrequency therapy of the trigeminal nerve and facial nerve. After operations, the symptoms of pain and spasm were relieved immediately, but the right facial numbness and facial paralysis (House-Brackmann grade III) were left. The facial paralysis was completely relieved after 3 months of follow-up, and there was no recurrence of trigeminal neuralgia or hemifacial spasm after 35 months.
Discussion:
Painful tic convulsif syndrome is a combination of ipsilateral facial trigeminal neuralgia and hemifacial spasm, which is relatively rare in the clinic. So far, only one treatment method of microvascular decompression has been reported for the disease. We report the first case of CT-guided extracranial radiofrequency therapy for painful tic convulsif syndrome.
Conclusion:
Extracranial radiofrequency therapy can provide safe and economical treatment for patients with painful tic convulsif syndrome.
