During neurosurgical procedures, it is sometimes difficult to understand the cortical anatomy of this region.Objective Find alternative ways to anatomically navigate in this region during neurosurgical procedures.Method We analyzed eighty two human hemispheres using a surgical microscope and completed a review of the literature about central sulcus region.Results In 68\/82 hemispheres, the central sulcus did not reach the posterior ramus of the lateral sulcus. A knob on the second curve of the precentral gyrus was reliably identified in only 64\/82 hemispheres.Conclusion The morphometric data presented in this article can be useful as supplementary method to identify the central sulcus region landmarks.<\/jats:p>","DOI":"10.1590\/0004-282x20150160","type":"journal-article","created":{"date-parts":[[2015,10,24]],"date-time":"2015-10-24T21:23:01Z","timestamp":1445721781000},"page":"934-938","source":"Crossref","is-referenced-by-count":14,"title":["Is the omega sign a reliable landmark for the neurosurgical team?
