The role of cryotherapy (cryoanalgesia) in the management of paroxysmal trigeminal neuralgia: a six year experience.

One hundred and forty-five patients with paroxysmal trigeminal neuralgia were treated with cryotherapy and followed up from 1 month up to 6 years. The mean nerve relief pain period was 13 months for the long buccal, 17 months for the mental and 20 months for the infra-orbital nerves and patients regained normal sensation long before the return of pain.
