[The neurodystrophic component of the structural changes in the hemispheric cerebellar cortex of patients with acoustic neurinomas].

Cerebellar specimens removed in surgical treatment of acoustic nerve neurinomas were studied morphologically in 16 patients. Histochemically, morphofunctional state of the vegetative adrenergic nervous fibers and endings of the vessels and connective tissue basis of the pia mater encephali in the region of the cerebellum indicates inhibited activity of the neuromediator contour of circulation and metabolism regulation in the brain. Light and electron microscopy in the cerebellar cortex detected disorders of circulation, nervous cell dystrophy, glyocytic proliferation. Correlation was found between activity of sympathetic component of the autonomic nervous system, severity of neurodystrophic changes in the cerebellar cortex and development of pathophysiological reactions arising intraoperatively and early after operation.
