[Prognosis of the outcome of the surgical treatment of the acquired lumbar spinal stenosis].

Not clear-cut indications exist until now for surgical interventions in lumbar spinal stenosis. The satisfying surgical results range from 55% to 98%. The purpose of the present case study was to optimize the data related with the neurological status, magnetic-resonance tomography and with defining the factors having an influence on surgical results.

[Features of cranio-cerebral trauma in victims of road accidents].

The paper deals with the specific features of brain injury (BI) in victims of road traffic accidents (RTA). RTA victims are most commonly pedestrians (62.6%) and less commonly drivers (17.

[The morphometric characteristics of the sagittal fissure as the basis for a surgical approach in callosotomy].

Macro-microscopic tomography of the sagittal fissure of the brain has been studied on 10 dead bodies, morphometric studies were performed in 10 healthy subjects (40 NMR-tomograms and 40 cerebral angiograms). The findings made it possible to divide the fissure into three zones and single out basic anatomical structures in each zone. Morphological and morphometrical data obtained provided validation of the approach to the corpus callosum and microsurgical callosotomy.

[A transmaxillary transnasal approach to tumors of the base of the skull].

The microsurgical transmaxillary transnasal approach provides a wide access to the midline of the skull base. Since 1994 the approach was performed in 11 patients while resecting malignant and benign skull base tumors by involving the cribriform plate, orbit, maxillary and sphenoidal sinuses, nasal cavity, clivus, and cavernous sinus. The technique is suitable for extradural tumors of the skull base and can be combined with transcranial approaches for more extensive lesions.

[The results of microvascular decompression of the accessory nerve in patients with spastic torticollis].

The results of microvascular decompression of accessory nerve in patients with spastic torticollis are reviewed. 40 patients with spastic torticollis were treated. Unilateral microvascular decompression of the XIth cranial nerve were used in 11 cases, lateral in 23 cases.
