The group saw that her silence in response to such an ordinary question was obviously rare. The people outside her heart felt that something was wrong and looked at the people outside her nerves.
Cao Yong pretended to be calm and said to his junior fellow apprentice: "Stop teasing me."
Huang Zhilei cried out in his heart that he was wronged: Who teased the little junior sister? It was definitely not him but you, Senior Brother Cao.
Walking into the operating room, the anesthesia was ready.
This time, Dr. Song was the lead surgeon and Dr. Pan was the assistant.
I have talked about scalp problems before. The scalp structure is divided into four layers.
The first layer of skin has richer blood supply than the skin in other parts of the human body, so once blood is lost, it is easy to suffer from hemorrhagic shock.
The second layer of subcutaneous tissue is also called the superficial fascia layer, where there are relatively large blood vessels and nerves. When Xie pressed the blood vessels in this area to stop the bleeding.
The three-layer galea aponeurotica is a special structure of the scalp. It is tough, elastic, and full of tension. It connects to the temporalis muscle in front and the occipital muscle in the back.

The location of the hydrocephalus drainage tube we mentioned before is hidden under this layer, that is, the fourth layer of the subaponeurotic layer. This layer has a loose structure, which is easy to separate the skin bag to place the shunt tube, and the upper structure is thick enough to cover and prevent the shunt tube from being exposed.
There is a subaponeurotic space under the subaponeurotic layer. The range of this layer can reach the back of the supraorbital margin to the superior nuchal line. The structure is very thin and easy to be torn. Therefore, most patients with scalp avulsion injury are torn along this layer, and we can see that many patients are torn to the ears above the eyes for this reason.
Needless to say, the last periosteum layer is the thin membrane covering the skull.
From the structure above, we can see that the scalp of patients with scalp avulsion injury contains the superficial fascia layer. This layer contains the important arteriovenous network and nerves that nourish the scalp. These arteriovenous network and nerves must be connected back to the large arteries and veins and nerve trunks of the human body, otherwise the scalp will die.
It can be said that if the scalp of a patient with scalp avulsion injury is to be transplanted back, anastomosing these important nerve and blood vessel trunks is the focus of the entire scalp transplantation operation for patients with scalp avulsion injury.
The medical students at the scene immediately racked their brains to carefully recall the scalp anatomy taught in the anatomy class.
The scalp is not a top priority in anatomy classes. If you don’t see real clinical surgical cases, it’s really hard to recall what you learned in anatomy classes. This is one of the main reasons.
Secondly, the dissection of dead specimens in anatomy class presents a relatively clean picture, unlike today's patients, where when the gauze protecting the wound is removed, the wound surface is inevitably full of blood because of the living life, filling the doctor's field of vision like a ball of blood and flesh, and it looks almost a mess.
Medical students are confused when trying to locate the blood vessels and nerves. Teachers also spend a lot of time trying to locate the anastomosis points, aligning them one by one and marking them one by one, but they are afraid of making mistakes. Once they make a mistake, the consequences will be disastrous.
Once again, it is verified that surgical anatomy is the foundation of the foundation. Doctors who are good at anatomy will not sweat a lot during the early stage of alignment. For those who are not good at anatomy, it is estimated that it will take more than an hour just to find the correct position.
It is normal to stay up all night for scalp transplant surgery for scalp avulsion. I didn't expect that a scalp surgery would not be as relaxing as a brain surgery.
