Is the omega sign a reliable landmark for the neurosurgical team? An anatomical study about the central sulcus region

Abstract: The central sulcus region is an eloquent area situated between the frontal and parietal lobes. 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… Show more

“…7 Numerous methods besides fMRI for identifying the central sulcus have been previously described on both CT and MR imaging. Most rely on identifying gyral and sulcal patterns and relationships, [8][9][10][11][12][13] which can be variable. Others involve complex image reformatting that most clinicians are untrained to produce or interpret.…”
