Half a year after the operation of the huge aggressive pituitary tumor, the vision decreased, the pituitary function was reduced, and there were three nasal surgeries, and this time the ** was larger.
Doctor: The cavernous sinus on the right side, that craniotomy, it's hard to open that piece with a one-time craniotomy.
Patient: Out of reach.
Doctor: Yes, yes, you can only take this side down as much as possible, craniotomy to remove this tumor, if you want to remove the whole degree better, he may have to pay a price after coming down, that is, this eyelid, the left eyelid may droop.
Patient: That's a high probability, right?
Doctor: Yes, there is a high probability, because this tumor is growing too fast, a small area to remove it, maybe the radiotherapy will not give you time and opportunity, you only have this kind of cavernous sinus to take out the inside of the sinus, this craniotomy you only need to take it down the eyelid drooping, this is called oculomotor nerve, it is responsible for this function, the probability of its damage is 90% For this kind of tumor, you see that there is a cauliflower thing coming out of the back, where does it come out it is a very small one called the oculomotor triangle, this triangle is 6 mm in size, 6 mm long, 3 mm wide, just such a small thing, this nerve comes out of the cavernous sinus, and after it comes out, these tumors are squeezed out. This nerve is very fragile, and you can imagine what state this nerve is in now, and some of them can't be seen at all during surgery. The normal anatomy and morphology of this nerve, after this tumor is cut, oops, this nerve is gone. Because it's thinner than paper.
Why didn't the nasal surgery hurt it, it didn't reach it, the tumor was separated by a membrane, and if you want to remove all of this, it will naturally disappear.
