Chapter 2416

"The other two are skin grafting, the difference is that it is divided into autologous skin grafting and allogeneic skin grafting."

"Autologous skin grafting, in simple terms, is to take the patient's own intact skin and transplant it to the damaged part of the patient's skin. Where is the skin eligible to be implanted on the patient's disfigured face? The answer lies with the patient. Butt, that is, butt."

Ha ha ha ha…

Hearing Wu Hao's words, everyone in the audience burst into laughter. They also didn't expect that the damaged face needed to be repaired with the skin on the buttocks. Some of the female audience members in the audience didn't even have to blush.

Wu Hao said with a smile: "Don't laugh, everyone, this has been fully researched and practiced. Because the skin of this part of the human body is the most delicate, it is relatively useless, because it basically does not see light, so the skin is relatively delicate and fair. And because it basically does not see much light, even if it is removed, outsiders cannot see it and will not be affected.

However, the desirable skin area of ​​the buttocks is limited, and the skin of the buttocks is different from the skin of the face. Without the contour of the facial skin, it cannot fit perfectly. Therefore, the skin implanted in this way can only serve as a concealment function, and may lose part of the function.

For example, the feature of blushing may not be realized on this skin, and some tiny expressions cannot be realized either.

On the other hand, after all, this has brought some harm to the patient. No one wants their buttocks to lose skin and become bumpy.

So at this time, medical experts have researched and developed another kind of skin grafting, which is allogeneic skin grafting. This kind of skin grafting has a more famous name, face replacement.

That's right, it's the face-changing technique talked about in many film and television dramas.

This kind of face replacement is very simple, that is, the donor's facial skin is removed and then implanted into the damaged patient's face. Although it is unreasonable to say that people's faces are different in appearance, these are determined by the internal skeletal muscle tissue, and the facial skin is a piece of skin.

So we can use this skin to repair the damaged facial parts of the patient. The skin with little difference can perfectly fit the damaged facial parts of the patient, and can perfectly connect with the surrounding intact skin.

The biggest advantage of this type of surgery is that it can be tailored to suit the individual's needs, how much is needed, how much is used, and the repair is performed perfectly, and the effect after repair is very good. In addition to some facial nerve tissue may be damaged due to surgical precision, resulting in some dysfunction. Others can basically achieve the same curative effect as the original face.

But, this face-changing technique also has some disadvantages or side effects. First of all, it may involve some ethical and moral issues, which is similar to the face-changing plot in film and television movies, and will bring a series of social problems.

On the other hand, it is the inherent problem of this technique, that is, heterogeneous rejection. This also means that patients will have to re-use anti-rejection drugs for the rest of their lives, which is a burden and even torture for patients.

What's more, there are very few such donors at present, so this technique is only applicable to a small number of people and cannot be popularized. "

Speaking of this, Wu Hao paused for a moment, then changed his tone and said: "Our skin graft has no problems in this aspect at all. First of all, it is printed from the patient's own somatic cells, so the source is different. There will be problems, and there will be no rejection.

And we can also customize the printing according to the patient's face shape and even some of the patient's own requirements, so as to print out a pair of skin that can completely fit the patient's face shape and is comparable to the original face.

Of course, due to technical reasons, we are currently unable to print out the entire face at once. It is not because of our technical reasons, but because the skin tissue we printed is alive, and it must be kept alive to be implanted on the patient's face and survive.

Theoretically speaking, once this kind of skin is printed, it should be implanted on the patient's face as soon as possible. The shorter the time, the better the survival and recovery effect. If it exceeds a certain time limit, the survival effect will be very poor.

But everyone knows that the speed of 3D printing is very slow. No matter what kind of printer it is, it needs to print out a little bit, which takes a long time.

Therefore, in order to keep the printed facial skin tissue alive and ensure its survival after transplantation, we can only reduce the printing area of ​​the skin. In this way, we need to print the skin in batches and then transplant it in batches, or through Multiple printers print out these skin tissues, which are then stitched and grafted.

Even so, the damaged face we repaired with this technology has a very good effect, basically reaching the level of the original patient's face.

After nearly a year of restorative treatment, Zou Feifei was finally cured and discharged from the hospital. Do you want to see what she looks like now? "

think!

Hearing Wu Hao's words, everyone in the audience shouted.

Okay, Wu Hao nodded with a smile, and then said to everyone: "Let us welcome Zou Feifei with warm applause, and let her tell us about her heroic deeds and treatment experience."

clap clap clap...

In the warm applause, Zou Feifei appeared on the stage, and then walked towards the center of the round platform with confident steps.

At this moment, Zou Feifei didn't have the slump in the ward, instead she was dressed like a successful urban beauty, her whole face was very delicate, her fair skin~lightnovelpub.net~ couldn't see any damage at all.

Zou Feifei walked up to the round platform while waving her hands. As for Wu Hao, he took the opportunity to get off Wu Hao to rest. After such a long speech, my mouth is already dry and my throat is smoking.

"Thank you Mr. Wu for giving me such an opportunity to restore my face, and to stand on this stage and share with you my mental journey during this period of time..."

Zou Feifei started from saving people to being rescued, and then went to Anxi to receive treatment. The big screen is some daily pictures recorded by herself with the lens. Especially after comparing the disfigured face with the current face, the audience burst into exclamations.

Everyone stared at Zou Feifei's face, and the camera also gave a close-up of her face. But everyone never noticed that this delicate and fair face was once so dilapidated.

This is simply too miraculous, as if a great transformation into a living person. What's even more miraculous is not only her delicate face, but also her piercing eyes, including her eyebrows and hair that have been completely burned away, all appear miraculously.

Although the current Zou Feifei still has handsome short hair like a boy, but the hair is very thick, and it doesn't look like it was burned at all.
