Surgical treatment of tumors of the supplementary motor area

Background . The supplementary motor area is a part of the medial frontal cortex, that located just anterior to primary cortex entirely within interhemispheric fissure. This belongs traditionally secondary and perhaps it least studied region brain. While functions symptoms damage premotor areas have been well known described for long time, study has limited fundamental neuroimaging electrophysiological researches, practical side issue clinical significance this remained outside interest researchers. Aim To present anatomical functional features area, its lesion, analyze all data available today aspects surgical treatment tumors in region. Materials methods A search scientific databases (PubMed, etc.) led selection analysis sixty-two literary sources. review mainly devoted risk factors pathologies localized Results According characteristics, heterogeneous - two separate subregions it. In addition function role also reliably established implementation working memory processes, language, perceptual, cognitive other functions. Such number performed by associated with numerous neural connections area. For example, aslant tract recently, connects superior gyrus pars opercularis inferior gyrus. tract, apparently, language dominant hemisphere non-dominant hemisphere. When affected, various neurological speech can occur, particular, syndrome, which characterized development akinetic mutism patients and, most cases, completely reversible few days or months. Among are common, especially gliomas, manifest themselves both preoperative postoperative periods. Conclusion Critically important planning, informing patient about spatio-temporal picture predicted disorders timing rehabilitation critically important. It recommended use intraoperative neuronavigation, as neurophysiological monitoring. necessary further peculiarities surgery order standardize approaches pathologies.
