Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 2964 [2964] Make the best use of everything

   "If you don't do the second CT, is it useful to start the navigation?" Huang Zhilei had to say that her idea was a bit strange, and he directly suggested to her, "You can completely skip the navigation, think for yourself, and your brain should be able to figure it out."

  Xie Wanying: …What does Brother Huang think of me?

   Little Junior Sister's brain is a super three-dimensional computer.

   "I want to use Navigation." Xie Wanying asked her brother, she didn't want to make herself appear to be a very strange person. Besides, there are advanced medical technology, make the best use of everything, why not use it to assist yourself.

   Brother Huang is as cool as Senior Brother Cao: "I'll turn it on for you."

   In fact, the three-dimensional navigation sticker positioning marker mentioned earlier uses the point registration method. Sometimes the positioning marker is afraid of being displaced and does not know, and will directly scan the patient's face with a laser scanner in the operating room to obtain a face-to-face pairing method called face-to-face matching. However, this method has limitations, and it is not very accurate for matching the back of the brain.

  According to the above principles, Xie Wanying used her own eyes to scan and position the patient's head, and then aligned it on the navigation software.

The biggest advantage of the    navigation software for her is that the three-dimensional images can be displayed on the screen more intuitively, which is convenient for her to discuss with other doctors. After all, it was too time-consuming and laborious for her to speak and draw the images in her mind.

   "Here and here." Xie Wanying took a cotton swab to draw the position of the opening that can be made on the patient's head.

  The anesthesiologists put their heads together and watched the strangeness.

   Lu Yanhan, who has never seen neurosurgery, asked in surprise, "Is this going to be an operation on the eyebrows?"

  Brow opening, which sounds like eyebrow surgery at first glance, is actually a very typical surgical approach in neurosurgery called the trans-brow keyhole approach. Make a small incision on the eyebrow, as Xie said, open a small bone window the size of a one-yuan coin. After entering from this position, the doctor can access the anterior cranial fossa and suprasellar area of ​​the brain. Operation.

There are many surgical approaches in neurosurgery. For example, in the previous case of hydrocephalus, there are three conventional approaches, and there are countless other unconventional approaches. Therefore, navigation is required to select the best approach map. .

  There are two options for the surgical approach proposed by Xie, one is from the eyebrow opening, and the other is from the hairline. The surgical approach from the point of the hairline is the pterional approach.

The pterional point is also the apex of the sphenoid, located in the anterior part of the temporal fossa of the skull, where the frontal, parietal, temporal, and greater wings of the sphenoid meet.

The meeting of the bones means that there are sutures here, which means that the bone here is relatively thin and easy to drill. It is also one of the classic approaches for neurosurgery, targeting the sellar area, the anterior cranial fossa, and the middle cranial area. Surgery is performed on the diseased area of ​​the fossa and the upper clivus.

   From the perspective of the human head, the openings of the two approaches are not too far apart, and the targeted areas partially overlap.

   For doctors, what are the elements that make the final choice?

   It must be mentioned that the principle of surgical approach selection in neurosurgery is to avoid excessive pulling on the brain tissue and reduce damage to the brain tissue. At the same time, the lesions should be exposed as much as possible.

   For the current case, which route is the easiest to find the parasite and the least damage to the brain tissue is the best.
