Analysis of the Anatomical Variations in Sylvian Fissure Using MRI

Abstract Background The most common surgical approach in neurosurgery to diagnose and treat tumors aneurysms is the transylvian-pterional approach. classification of Sylvian fissure (SF) was proposed based on pure anatomical observations by Yasargil. SF identifiable feature superolateral brain surface, which divides parietal frontal lobes from temporal lobe lies below. Aim aim identify variations (bilaterally) normal population its morphological asymmetry. Setting Design This a retrospective, observational descriptive record-based study done asymmetry healthy using 1.5-T magnetic resonance imaging (MRI) system. Materials Methods classified into five types. categorization MRI, either T1-weighted images three planes. Statistical Analysis Percentage frequency SPSS 23.0. Results In this study, we found that type 4 general 100 patients. We 1 age groups above 50 up 60 years age. Types 2 were all groups. Bilateral presentation can be considered as symmetric 85% asymmetric 15% study. Conclusion Classification types MRI shown reliable practicable. Sound knowledge anatomy before help reduce procedure-related morbidity, ischemic lesions, or edema.
