Chapter 3063 【3063】Poor Cognition

Hearing this, I seem to understand a little bit, but I don’t seem to understand a little bit. A troubled look flashed across the patient's face.

Such a situation once again tested the degree to which a doctor can touch a patient's brain.

"I think what you're confused about is exactly where this place is located. Having said so much, it's hard to imagine without an actual reference." Xie Wanying said.

Lin Jiayin nodded: "Yes. Doctor Xie, where is it? Does the bottom you mean mean the bottom of the brain?"

"It's the bottom, the bottom of the cup." Xie Wanying picked up a cup on the table, pointed to the bottom, and showed the patient, emphasizing that the other party heard correctly.

The patient's expression showed distress again: "The bottom is at the bottom of my head, isn't it the chin?"

Sure enough, this is the understanding of ordinary people. The bottom of the head is the chin.

The bottom of the skull is definitely not here under the chin. The chin is the lower part of the mouth. We know that the continuation of the mouth is the throat, esophagus and trachea, which has nothing to do with brain tissue.

"We touch the back of the head is the occipital bone. The front point of the occipital bone is the two temporal bones, and the temporal bone connects to the sphenoid bone in the middle. The mouth is the mandible, and the famous temporomandibular joint is connected upward to the temporal bone. Look at the height of the mandible. It almost reaches the ear. Therefore, the sphenoid bone is more accurate. The level of the sphenoid bone body in the middle does not reach the chin, and it has to be lifted closer to the nose. There is an important structural point in the sphenoid bone called the sphenoid sinus. It communicates with the nasal cavity."

After a doctor compared and explained with a specific and intuitive reference, the non-medical people on the scene suddenly became enlightened. Usually laymen understand that most of the horizontal line of the brain goes to the chin, which is wrong. In fact, you can know by touching the back of a person's head. If the back of the head is going upwards, it is destined that most of the brain tissue will not reach the very bottom, that is, the cerebral hemispheres will not reach.

It is not too difficult to understand that the brain and the nose are connected.

Because of the nasal leakage of cerebrospinal fluid in patients with traumatic brain injury as we mentioned before. If you think that cerebrospinal fluid usually does not flow out from other places but only from the nasal cavity, there must be some human body mystery here. Now the answer is revealed, it is due to the sphenoid sinus.

The sphenoid sinus is an opening that communicates with the nose. The sphenoid bone houses the brain, and the sphenoid sinus naturally becomes the natural window through which the brain communicates with the nose.

On the other hand, there is such a natural opening as the sphenoid sinus that leads to the outside world through the nose. There seems to be a natural opening in front of the doctor, forming a hole for drilling. You can pass through this opening without opening the skull and directly touch the brain that is densely wrapped in the skull. .

The mouth of the sphenoid sinus is very small, and the doctor cannot go in and operate it with bare hands. It was located so deep in the nose that the doctor's eyes couldn't see it. Doctors can only use special surgical instruments to drill through this small hole.

Such a surgical method sounds familiar. Yes, we can quickly think of other parts of the human body with similar surgical principles and methods, such as gastroscopic surgery such as colonoscopic surgery. This type of operation is to use the natural opening of the human body to access the inside of the human body without using a scalpel to open the human body.

The instrument used in gastroscopic surgery is called gastroscope, the instrument used in colonoscopic surgery is called colonoscope, and so on, the instrument used in surgery through the nose is called nasal endoscope.

From the above, we can know that nasal endoscope can perform nose surgery and brain surgery.
