Trigeminal neuralgia--treatment of the third division by radiologically controlled cryoblockade of the inferior dental nerve at the mandibular lingula: a study of 31 cases.

Cryoblockade of the peripheral nerve affected by trigeminal neuralgia is an established technique for treatment. Freezing the inferior dental nerve using C-arm image-intensification control, and a nerve stimulator to guide the slim Spembly Lloyd probe, offers an additional technique for treatment of a small number of patients with trigeminal neuralgia. This paper reports the results of 31 cryoblockades of the inferior dental nerve in 11 patients.
