Abstract
✓ The development of accurate techniques for spinal stereotaxic surgery facilitates the difficult management of post-herpetic facial pain by making possible destruction of both the spinal trigeminal nucleus and descending tract; it also elminates excitation from the nuclear overlap between cervical and facial segments and intranuclear pathways. The technique is described and three cases reported. Stereotaxic trigeminal tractotomy relieves both the hyperpathia and deep background pain of herpes.
