Electrophysiological monitoring, spinal meningiomas, electroneuromyography, somatosensory evoked potentials, electromyography


Spinal meningiomas produce lesions of spinal cord at any level. Surgery remains the main method of treatment for spinal meningiomas. The goal of surgery is total surgical resection of tumor without causing neurological deficits. Many factors affect the ease of complete surgical resection, including the tumor's location, size, or consistency; the extent of vascular and neural involvement. The clinical aspects of spinal meningiomas are reversible postoperator in a large measure.

The present study is based on the investigation of four groups: the first essential group 35 patients with spinal meningiomas, the second group – 12 patients with medular neuromas, the third group – 10 patients with ependymoma and 25 healthy volunteers.

The electrophysiological examination plays an important role in the diagnosis, evolutionary prognosis of spinal meningiomas pre and postoperatively, it includes: electromyography, electroneuromyography, somatosensory evoked potentials which permit to establish the level, degree and sometimes even the mode of medullar impairment.

The methods of imaging diagnosis of spinal meningiomas play the decisive role in elaboration of a suitable surgical treatment. Was established a surgical differential tactic for surgical resection which depends on the tumor's location, size, or consistency and which allows the surgeon to determine the type, the size of surgical approach and the method of electrophysiological investigation.
