The first step to splitting the Sylvian fissure involves dissecting at the level of the Sylvian point, then extending to the level of the M2 branches and insula. What layer encasing the veins will be encountered next? #MedTwitter #Neurosurgery #NSGY #surgery

After initially splitting the Sylvian fissure, a superficial thick arachnoid layer is encountered. This may be disrupted using fine forceps or microscissors. A microcotton ball is used to keep the dissection planes open. Learn more here| zurl.co/RwxN. #MedTwitter
