 clinical coordination pertaining to the temporal region is injury to the lateral surface of the skull which can fracture the t-reon and can rupture the middle meningeal artery which runs right under the t-reon and lead to extradural hematoma which can be life-threatening. In such situations it is necessary to do what is known as a burr hole and so here one of my assistants is going to do the burr hole. So let's take a look at the landmark that we can use. So this is the zygomatic arch. We take the midpoint of the zygomatic arch and we go approximately one and a half inches above that where my finger is pointing. So this is the approximate location of the t-reon and this is the place where we will split open the temporalis muscle and my assistant is going to split open the temporalis muscle. So come here and split it open like that. Make an incision along the line of the temporalis muscle. Make an incision along the line of the temporalis muscle. Good. Now split it open deeper. Good. That is the region of the t-reon. So once we have split open the temporalis muscle and then we open it this region that we see here this is the region of the t-reon and here we make a burr hole and we evacuate the hematoma and like it the middle manager artery. So this is the principle of evacuating a middle manager artery hematoma. Please like it sir. Thank you very much. Okay thank you very much ladies and gentlemen.
