The idea of surgery is often that if your patient lacks something, you will find a way to autotransplant it from other parts.

For example, Chen Qi had rhinoplasty before, because of the lack of nasal bones, he cut a part of the ear cartilage or rib cartilage to replace it.

Another example is burn skin grafting, where the skin is burned out, and a part of the skin graft from other parts of the body is replaced.

But now there is a problem, what should the patient do if he is missing a piece of his facial skull?

The maxilla, which is located in the middle of the face, has one on the left and one on the left, and is connected to each other to form the scaffold for the midface.

The maxilla has bony prominences connected to the body and four adjacent bones, such as the frontal process is connected to the frontal bone, the zygomatic process is connected to the zygomatic bone, the palatal process is connected to the left and right in the suture of the middle palate, and the alveolar process is the bone of the part where the tooth is located.

If the maxilla is defected due to a tumor, it will directly affect the appearance of the face, and the depression in the middle of the face is very unsightly.

Because the eyeball, nasal cavity, and suborbital area of the maxilla lose bony support, many functions will be affected.

For example, eye movements are restricted, resulting in double vision;

Nasal cavity collapse, nasal dryness or pus;

Because the oral cavity is directly connected to the nasal and maxillary sinuses, speech is not clear, and food will enter the nasal cavity when eating;

Some maxillary defects can also affect the opening of the mouth and other functions due to inflammation.

Therefore, maxillary defects not only seriously affect social function in appearance, but also affect all aspects, including speech, swallowing, eating, mouth opening, and breathing.

If Xiao Wenxiang's bone was a "convex" shape before the operation, then it may become a "concave" type after the operation, so what is the significance of the surgery?

Professor Ge is still very worried:

"Chen Qi, what now? The maxilla is gone, so we can't just stitch it up, right? ”

Chen Qi is a little strange:

"Lao Ge, although the loss of the maxilla is a big problem, it is not untreatable, what do you have to worry about, do you think that the loss of the maxilla cannot be repaired now?"

Chen Qi has realized that it may be that his cognition in his past and present lives has been biased, and he may not have done maxillary repair in 1990.

Sure enough, Professor Ge said angrily:

"How do you make up the maxilla? Even if I knocked out some bones and filled the hole, how would I fix it? This is not a handicraft, and the broken area can be glued with glue. ”

Chen Qi thought to himself, no wonder this old man was in such a hurry.

"Although the bones can't be glued together, we can use gaskets to help fix them like carpentry."

Ge Minghua glanced at Chen Qi:

"Gasket, your idea is good, but I haven't heard of the principle of gasket at all, besides, even if you can use gasket, how to choose bones? What part of the bone will be used to fill the hole? ”

Chen Qi smiled: "Okay, okay, I know the true level of you, a professor at Peking University, since I am the main knife, of course I have thought about this kind of thing." ”

Chen Qi looked at the head nurse again at this time:

"Head nurse, please help me bring that box, yes, just that box, and then you open it."

The head nurse didn't know why, but the rule of the operating room was that the chief surgeon was the biggest, so she obediently obeyed, and then took out a silver-white metal piece from the lockbox.

Professor Ge blinked, and had a guess in his heart: "Chen Qi, this is ......"

"Yes, this is the metal gasket I prepared, this thing is very precious, we haven't bought it in China."

"What kind of material is this?"

"Titanium."

"Titanium?" Professor Ge and the others were shocked again.

Titanium alloy was not a news thing in a few decades, but in 1990, titanium alloy represented the latest materials science technology of this era.

In this era, titanium alloys were mainly used for military purposes, such as the manufacture of compressor parts for aircraft engines, followed by structural parts for rockets, missiles and high-speed aircraft.

Moreover, in this era, titanium alloys are expensive and expensive, and almost all of them need to be imported.

Our own country's research on corrosion-resistant titanium alloys and high-strength titanium alloys is still quite backward, of course, it was later accelerated to narrow the gap.

A few decades later, that is, the era when Chen Qi worked in his previous life.

Titanium alloys have been widely used in the medical field because of their high strength, low density, non-toxicity, good biocompatibility and corrosion resistance.

It is the preferred material for medical products such as artificial joints, bone trauma, spinal orthopedic internal fixation systems, dental implants, artificial heart valves, interventional cardiovascular stents, surgical instruments and so on.

Shocked, Professor Ge hurriedly asked, "Chen Qi, where did you get these titanium materials?" ”

Chen Qi thought to himself, am I going to tell you that these are all taken out of the material warehouse in my space operating room?

"Uh, these titanium materials were originally purchased by me from the United States, purely private money, for experimental surgery, this is not to see the pity of the little patient, so I deliberately took it out, or this money will be reimbursed to me by the Third Hospital of Peking University?"

"Phew, the patient's surgery fee still owes us a lot, how can we make it up to you in the Third Hospital of Beijing Medical University? But this titanium is really a good baby, do you have a lot? Send me a few? ”

This time it was Chen Qi's turn to roll his eyes: "What do you think?" It's such a small piece, a few thousand dollars. ”

In fact, Professor Ge is a little cautious, Peking University is a top university, what kind of laboratory is not? If you can get a piece of titanium alloy material and study it at that time, you may be able to promote the development of medical titanium alloy.

It's done, but it's a big gold mine.

At this time, in the multimedia classroom, everyone saw that the head nurse had taken a few silver-gray metal plates, and they were also confused.

"What is this?"

"It feels like some kind of metal object, I guess it's done to repair the missing bones, right?"

Because at this time, it can be seen in the lens that the surgeon is comparing the "leakage", which is obviously to be repaired.

"For repairs, ordinary metal materials can't work, right? This is a rejection reaction. ”

"No, no, this will not be a titanium alloy material, we also have this thing in the orthopedics, but the shape is different."

"Huh~~~ This Peking University Hospital is really wealthy, and titanium alloys are on it."

Meng Yushu was also saying to the people next to him at this time:

"This Lao Ge is not afraid of bankruptcy, if it is really a titanium alloy, it will cost tens of thousands of yuan, and there is money that may not be able to buy it, and he is really willing to do it."

"It seems that Comrade Lao Ge not only has a high level of medicine, but also has a very high ideological realm, which is worth learning from."

Meng Yushu glanced at the doctor next to him and continued to look at the TV screen.

At this time, the doctor can be seen on the TV screen disinfecting the patient's buttocks.

Several little doctors were surprised: "No, this is not a surgery on the skull, how can the buttocks be sterilized?" Isn't this incompatible? ”

A professor at Jishuitan Hospital smiled:

"You don't know that, do you? Professor Ge is obviously ready to use the patient's own iliac bone to fill the hole after the loss of the maxilla, which shows that Professor Ge's clinical level is closely in line with the international mainstream technology, which is very powerful. ”

"Oh~~~ I see."

"Professor Ge turned out to be so powerful, he is really a professor at Peking University, and he is a big man who wants to run for the member of the department."

"No wonder he dares to take on patients that others dare not accept, it seems that this year's by-election is none other than Professor Ge."

Professor Ge has successively adopted several new surgical methods and completed one difficult surgical step after another, which is an eye-opener for onlookers.

In comparison, professors such as Meng Yushu and Fang Bing are bleak.

After all, when people perform on stage, they can only sit under the stage as an audience, and the level gap is judged.

At this time, Chen Qi had already quickly cut open the anterior skin of the iliac bone and began to take the bone.

What's worse is that the bone of the iliac bone is also very hard, and Chen Qi had to let the chainsaw play again, and he didn't dare to cut more.

The removed iliac bone was fixed on a titanium alloy plate, and Chen Qi fixed a piece of bone with titanium plate on the skull of the little patient, fixed it with screws, and the rest was to let the osteoblasts and osteoclasts in the periosteum slowly fuse.

Finally, Chen Qi took the mandible and put it on the joint like a machine part, and the entire bone operation was completed.

After doing all this, Chen Qi motioned for the camera to zoom in and gave a close-up of the repaired facial skull.

The whole wound is clean and refreshing.

At this point, the experienced old professors saw that the operation was successful.

Just like building a house, the load-bearing walls and columns have been built, and then there are some decoration works left, which is the simplest job.

Chen Qi then put the two eyeballs back into the eye frame, and also used a new material net pocket to fix them.

Excess tissue is then removed from the face, and the entire skin is stitched back together.

Of course, for the layman, this face is completely unseemly, because the facial features have not yet been fully reflected, but for the expert doctors, the operation is over.

After Chen Qi finished the last stitch, Professor Chong Ge nodded.

Professor Ge was so excited that he really wanted to hug Chen Qi and kiss him.

But now that it is live broadcasting, Professor Ge forcibly suppressed his excitement and pretended to be calm and said:

"Okay colleagues, this is the end of today's osteoporodysplasia surgery, thank you for watching, please criticize and correct the deficiencies, if the surgical video is needed, you can contact the Science and Education Department of the Third Hospital of Beijing Medical University, this live broadcast ends here."

Turning off the live camera, Professor Ge was about to cheer, but found that Chen Qi was no longer in the operating room.

"Hey, Chen, where's Chen Qi?"

Chen Qi ran to the toilet as fast as he could, and then happily put the water back.

"Damn, hold your urine all day long, and sooner or later you'll have prostate disease."
