[Ultrasonic destruction of the spinal trigeminal nucleus in the deafferentation orofacial pain syndrome].

Ultrasonic destruction of the trigeminal spinal nucleus was conducted in 12 patients with the deafferentation orofacial pain syndrome. The etiological factors and clinical manifestations of the deafferentation syndrome are analysed. The surgical techniques of destruction of the trigeminal spinal nucleus and the principles of intraoperative electrophysiological control are described. The length of the nucleus destruction and the clinical effect of the surgical intervention are compared. To relieve pain and dysesthesia in the peri- and intraoral areas the terminal nucleus must be destroyed at the level of the obex of the fourth ventricle.
