[Music] the other thing which that i want to show this is for example is a super obvious rim has been taken out that allows me to change the trajectory particularly if i have a supracellular vision or in this case for example is a hydride invasive artery annually it's going up both the dorsum cell as you can see these torsos always above it so in that case if i take down the super obvious rim allows me to incline the trajectory of well right so that taking the orbital rims allows me to go a little bit more superior that's why i do the supra audio ring without taking the zygoma on so that's you can see in this case again this the high rising basic artery and just by taking down i can change the trajectory allows me to be a little bit more bezel uh and then you can see once i take the posterior clinoid i have a much better visualization of the output for the upper third of the climates all the way down to the eye so these maneuvers we needed from skull-based surgery i think everybody has to be familiar this is some animation i use particularly for working with with our residents because you can see around again once i take all these bones and it is like exaggerating i think the anterior kind of process for steroid process you can see the entire antenna of the cell at 37 so you can see the base your tip you can see the picom you can see p1 p2 on this side i can see you also p2 on the other side i can see the pituitary gland pituitary stock so i can have a beautiful look around this this is supra tentorium it's infrastructorial so you differentiate the supra from infra tutorial this is going to be the carbon sinus with the uh oculomotor nerve trochlear nerve the third i mean d1 which is latin lacrimal frontal and you can see the six nerve behind this the distal dura ring carotid can be mobilized this is a beautiful view to maximize but you can see how we maximize this potion by taking down basically hey everyone ryan rad here from neurosurgerytraining.org if you like that video subscribe and donate to keep our content available for medical students across the world
