Speaking of harelips, the first thing many people think of is Li Yan.

Because she is a second-generation celebrity, Li Yan's cleft lip is inevitably known to the public, and at such a young age, she can only cope with the public gaze through inner self-adjustment.

Many people blame Faye Wong, saying that it was her disorderly life, smoking or drug abuse that led to the child's tragedy.

In fact, there are many causes of harelips, and we cannot blame them all on Faye Wong.

Today, the editor will discuss it with you.

What is a harelip?

Cleft lip, also known as cleft lip, is a common congenital malformation of the oral and maxillofacial region, with an incidence rate of approximately 1 in 1,000.

In a normal fetus, after the fifth week, some embryonic protrusions gradually merge with each other to form the face. If the fetus fails to develop normally, deformities may occur, including cleft lip.

What are the dangers of harelips?

According to developmental defects, harelips can be divided into unilateral cleft lip and/or palate, or bilateral cleft lip and/or palate.

Because some readers previously reported that the photos caused discomfort, I will not post specific photos today.

But everyone has to know the dangers of harelips.

Unsightly.

Regardless of whether it is unilateral or bilateral, patients with cleft lip have clefts in their lips, varying in size. The larger ones can reach into the nostrils, and are often accompanied by nose alar collapse, which seriously affects the beauty of the human facial features.

Causes sucking dysfunction.

We all know that breast milk is the best nutrition, but it is difficult for children with cleft palate to breastfeed normally.

Because the incisors are deformed and protruding, and the front teeth are cracked, the pressure in the baby's mouth is not enough. When feeding or drinking water, it is easy for the baby to choke into the trachea or flow into the ears.

Milk that accidentally enters the trachea and reaches the lungs can cause inflammation and develop into pneumonia; milk that flows into the ears through the throat can easily cause otitis media, with pus or strange fluid flowing out of the ears.

Affects pronunciation.

The lip is one of the speech-making organs. Children with cleft lip disease cannot pronounce words clearly when speaking, which affects pronunciation.

This will affect normal communication and interpersonal interactions in the sick children's later lives.

Eating rabbit meat can lead to harelips. What is the truth behind causing harelips?

First of all, the editor wants to tell you responsibly: "You get harelips from eating rabbit meat?" This statement is completely nonsense.

The occurrence of harelips has both congenital and acquired factors.

Congenital factors? Genetic studies believe that cleft lip is a polygenic hereditary disease.

Heredity accounts for 40-60% of the causes of orofacial clefts.

The specific data are as follows: (1) If both parents are normal: the probability of giving birth to the first child with cleft lip and palate is 1:600.

(2) If both parents are normal and have one child with cleft lip and palate: the probability of giving birth to a second child with cleft lip and palate is 1:20.

(3) If both parents are normal and the first and second children have cleft lip and palate: the probability of giving birth to a third child with cleft lip and palate is 1:4.

(4) If one parent has a cleft lip and palate patient: the probability of giving birth to a child with cleft lip and palate is 1:20.

(5) If one parent has a cleft lip and palate and one child has a cleft lip and palate: the probability of giving birth to a second child with cleft lip and palate is 1:4.

(6) If both parents are patients with cleft lip and palate: the probability of giving birth to a child with cleft lip and palate is 1:4.

Acquired factors? Environment During the most dangerous first trimester of pregnancy, if the mother's physiological state is invaded or disturbed, it may affect the growth and development of the embryo's maxillofacial region, leading to harelips.

Generally speaking, the fetal mouth and nose initially take on the adult shape in the first stage of pregnancy, that is, 12 weeks. During this process, the mother is unfortunately infected with a virus and is stimulated by hormones or anti-tumor drugs, antihistamines, tobacco and alcohol.

etc., may cause a series of aberrations such as genetic mutations.

Acquired factors? The vomiting and partial eclipse of undernourished women during pregnancy can affect nutritional intake and cause vitamin deficiency. In animal experiments, when pregnant mice are fed food lacking vitamins A and E, the young mice born often have cleft lip and palate.

.

In addition, smoking and insufficient folic acid intake may also play a role.

Smoking during pregnancy can increase the risk by up to 30%.

Acquired factors? Other possible risk factors include various occupational chemical exposures, high fever, mental stress, maternal obesity, oral hormone supplements, ionizing radiation, and certain maternal infections, which may lead to cleft lip.

The treatment time for cleft lip is only for babies with cleft lip. Generally, when the child is 3 to 4 months old, he can go to the hospital for cleft lip repair surgery. Most of the time, no obvious traces will be left.

If there is a cleft palate at the same time, in order to facilitate the baby's feeding and correct pronunciation in the future, some repair surgeries will be performed.

Early surgical repair is the only effective treatment for orofacial clefts. The purpose of surgical repair is to solve the function of the mouth and nose and correct the appearance deformity.

Specifically, reconstruct a complete and appropriately sized upper lip, and try to restore the function of the orbicularis oris muscle; repair the palatal cleft to rebuild the integrity of the palate, isolate the oral and nasal cavities, and reconstruct perfect breathing, chewing and eating functions; maximum

Correct appearance defects and eliminate negative psychological effects to a certain extent.
