Surgical treatment of glial tumors of the frontal lobe. Current state of the problem. Part I: motor functional system

In everyday clinical practice, neurosurgeons usually deal with glial tumors localized precisely in the frontal lobe. There is a widespread opinion that almost any neurosurgeon can resect glioma of the frontal lobe regardless of experience and microsurgical skills. However, working at the federal center, we observe how employees often have to operate on patients with frontal lobe gliomas after previous surgery in other hospitals. Therefore, treatment of these patients seems to be quite difficult problem of neurosurgery for glial tumors, and incidence of postoperative complications is still high. We analyzed literature data on anatomical and functional aspects of surgery for frontal lobe gliomas and practical nuances of their surgical treatment. Motor functional system of the frontal lobe is represented by several cortical zones united into a complexly organized network of functional connections through associative fibers. Theor lesion can lead to postoperative motor deficit.
