FIELD: medicine, neurosurgery.
SUBSTANCE: the present innovation deals with treating patients with extramedullary spinal meningiomas. After removing meningioma one should treat intact dura mater along its periphery at the distance of 0.5-1.0 cm against tumor growth area, and then - tumor growth area from periphery towards the center with defocused ray of ND-YAG laser at 30-40 W power and ray's diameter being 4 mm, not more for 5-7 min. The method enables to decreased traumatization of spinal cord and probability of relapse development.
EFFECT: higher efficiency of prevention.
