title: Clinical review of nucleus caudalis dorsal root entry zone lesions for facial pain.
abstract: Twenty-seven patients with intractable facial pain underwent dorsal root entry zone thermocoagulation lesion of the nucleus caudalis of the spinal trigeminal nucleus. Retrospective review revealed a success rate of 85% in the immediate postoperative period declining to 52% on subsequent follow-up. The best results were in the subgroup of patients with postherpetic neuralgia, of which 67% achieved definite relief. There tended to be some correlation of satisfactory results and pain quality as well as extent of pain along trigeminal territory. The operative morbidity was low although most patients were observed to have a mild transient ipsilateral dysmetria.
