The wind tears the eyes, that is, the wind crys, and its causes are divided into physiological and pathological causes.

There are three main physiological reasons. One is that the amount of tears secreted by the tear glands exceeds the range that the tear duct can discharge, so it overflows outside the eyes to form tears, such as crying.

Second, the tear glands are stimulated by cold air or cold wind, which reflectively causes increased tear secretion.

After the piercing point and the piercing tube are stimulated by cold, spastic contraction occurs, causing the amount of tears to absorb smaller, so that the extra tears flow out of the eye surface to form tears.

The third is eyelid relaxation.

This is more common in middle-aged and elderly people. Their tear ducts are unobstructed, but due to the loose skin of the eyelids, the muscle capacity around the eyes decreases, and the siphon effect of tears is reduced, resulting in poor tear elimination and tears.

As for pathological causes, there are more tears.

It is mostly caused by eye inflammation, such as conjunctivitis, trachoma, blepharitis, etc., as well as trauma, tumors, etc., which cause lacrimal duct stenosis or obstruction.

Yan Feifan observed Ma Weixia's friend, who was only in his early twenties, and although his eyes were a little red, he had no symptoms of inflammation.

Yan Feifan further learned that the young woman only saw Feng crying with her left eye, but her right eye was not very obvious.

Considering that this person has seen a doctor, Feng Cai Eye is not a complicated disease, but it still doesn't get better after treatment...

Yan Feifan guessed that perhaps it was due to trauma in the hidden place, tumor or abnormal development, which caused the left tear duct to be squeezed.

After obtaining the woman's permission, Yan Feifan took out a pair of surgical gloves from the car and put them on, and started an examination of the woman's face.

Yan Feifan really found this check a little unusual.

The upper part of the young woman's left incisor teeth has an upward bulge that is different from that of ordinary people, causing her nasal septum to deflect and deform.

Ectopic tooth!

This is the first reason Yan Feifan thought of.

So many of our teeth do not grow obediently. They have a smaller probability of growing horizontally or even growing upside down, forming ectopic teeth that are troubled by us.

However, due to the slow growth of the teeth, the discomfort caused by its ectopic invasion is quite mild and is often overlooked by us.

It will not be noticed until it grows big enough that one day due to inflammation or other reasons, the discomfort symptoms suddenly worsen.

Regarding the young woman, Yan Feifan analyzed that she should have a hyperplasia front teeth inserted upside down and arched into her nasal cavity.

As the tooth continues to grow, it arches the surrounding muscle tissue or forms a cyst, squeezing the left tear duct.

Yan Feifan took back his hand for the examination and took off his gloves while reminding him: "Go to the oral surgery department of the hospital and do a tooth ct."

"If no problem is found, come to me again!"

"Is it because of my teeth that caused me to cry my eyes?" The young woman confirmed, obviously with suspicion.

Ma Weixia maintained: "A Lian, Dr. Yan is a famous genius doctor in the affiliated hospital. He must be whatever he says."

Yan Feifan smiled and said, "I am not that amazing. It's just an analysis of mine. It needs further inspection to confirm."

After pausing, he asked again: "Do you have some symptoms of discomfort on your nose for a long time?"

"For example, nosebleeds, soreness, poor breathing, etc."

The young woman said in surprise: "I have allergic rhinitis. In recent years, my nosebleeds have to be bleeding five or six times a year."

After hearing what she said, Yan Feifan affirmed his analysis.

"Go to the hospital for a dental CT examination..."

This casual inspection delayed Yan Feifan for three or four minutes.

He and his sister, Yu Suye, returned to their residence on the seventh floor, and saw a sumptuous dinner on the dining table in the restaurant.

There were a few dishes on the dining table, which was the first time they met, and it was obviously not the style of Aunt Du Qiu.

Duan Yu said embarrassedly: "I was a little bored, so I helped Aunt Du make a few dishes."

"I'm not good at cooking, don't dislike it..."

Facts have proved that Duan Yu is a realistic guy, and he is not pretending to be modest.

The few dishes she cooked in the kitchen were only ordinary, and the taste was obviously heavy and oily. This was a bit difficult for the Yan family siblings who were increasingly particular about their diet.

Yan Feifan bit his teeth and tasted every dish, saying hypocritically: "It's still good."

"However, Duan Yu, it's important to take good care of your health and recover. Don't rob Aunt Du's job."

After pausing, Yan Feifan changed the topic and said: "Duan Yu, I have read the information on your comrade's cranial clots."

"If he comes to Binhai for convenience, he will come to the affiliated hospital next Monday."

"It is convenient to go to Beijing, so let him go to Baining Hospital. I will have the surgery for him this Sunday."

Duan Yu said happily: "Doctor Yan, thank you. I will tell my comrades about this good news later."

She also realized that the few dishes she made were not very popular, so she decided not to do such thankless things in the future...

At this moment, under the leadership of Pan Jichuan, Yu Beihua visited a small apartment in Shengjing Apartment on the east side of the affiliated hospital.

This small apartment, which is less than 50 square meters, is clean, has complete furniture and appliances, and is equipped with kitchen and bathroom, which is considered to be a level of moving in with your luggage.

Moreover, this apartment also has a small enclosed balcony. Standing on the balcony, you can see most of the scenery of the affiliated hospital.

After carefully checking it, Yu Beihua was very satisfied.

"It's here, you don't need to see other places."

"Dr. Pan, thank you!"

Pan Jichuan said with a smile: "You're welcome, it's good to help you. This apartment will be rented from half a year and will be paid every six months, and it will be 4,500 yuan per month, and a deposit of two months."

Yu Beihua was slightly stunned and said, "Doctor Pan, I still know some of the rent level here."

"How come a house like this must have 6,000, right?"

Pan Jichuan smiled and said, "We are brothers of the same school, how can we make more money from you?"

Yu Beihua smiled and said, "So this is your house."

Pan Jichuan smiled and said, "Doctor Yu, let's make a promise first. This cheapness is not for you in vain."

"It's too late to work or on duty at night, so it's not convenient to go home. I have to give me a few hours of rest here."

Pan Jichuan added: "Of course, I sleep on the sofa in the living room and don't huddle with you."

Yu Beihua laughed and said, "No problem!"

"Let's go for dinner, I'll treat you..."

Before he could finish his words, his cell phone rang.

Yu Beihua took out his cell phone and saw that it was Yu Youyi's call.

"Grandpa Six..."

"Yeah, it's done."

"that……"

Yu Beihua hesitated for a moment and said, "It's Dr. Peng Zhanghua from the oral surgery department and his surgical assistant."

"Dr. Peng has a very high opinion of this surgery."

“How tall is it?”

Yu Beihua hesitated and said, "He just said vaguely... it is the top level in the country, so I didn't say much about anything else."

“Surgery video?”

Yu Beihua said in embarrassment: "Grandpa Six, I have to ask Teacher Yan for instructions first."

"Oh, yes, Grandpa Six, I get it."

Yu Beihua and others finished the call, put away their cell phones, sighed, and explained to Pan Jichuan beside them: "My sixth grandfather is Dr. Yu Youyi, who is famous for oral surgery in our Yu family."

Pan Jichuan was a little surprised and just nodded, very sensible and didn't say much.

At this time, his cell phone also rang.

It was his mother's call!

"Cosmetic surgery? Who?... it's her again!"

Pan Jichuan showed a sarcastic expression and said, "It's okay to ask my teacher to take action. Let her prepare a guaranteed operation fee of 2 million yuan first."

"So high?"

"Mom, it's not a question of whether the price is high or not, but that you have money, and my teacher is too lazy to take action, and there is no time to take action."

"Mom, I tell you, I don't know how many people are waving checks and waiting in line for the teacher to let go."

"Mom, just tell her that asking the teacher to let go is the limit I can do, and it is impossible to be cheap in terms of cost."

After finishing the call with her mother, Pan Jichuan sighed with disgust: "A relative who doesn't take advantage of it."

"Doctor Yu, let's go, let's have a meal..."
