Etiology:
The factors leading to cleft lip and palate are not fully understood, but may be related to the following factors:
① Genetic factors: Genetic studies have proved that this disease is polygenic, and 20-30% of patients have positive genetic factors. We often see similar deformities in patients' relatives.
② Environmental factors: vitamin deficiency during pregnancy, mother's infection with virus during pregnancy, exposure to X-rays, hormones or anti-tumor drugs, antihistamines, alcohol and tobacco, etc. , may cause a series of genetic mutations and other distortions.
To sum up, there are various teratogenic factors, but they are not very clear, which can be simply considered as a polygenic genetic disease.
Symptoms:
Cleft lip is not good-looking, and it affects breast suction, pronunciation and alveolar bone development.
Treatment:
Cleft lip and palate seriously affects aesthetics, swallowing, pronunciation and psychology. Cleft lip is mainly treated by surgery. It is generally believed that the appropriate treatment time for cleft lip is 3-6 months. Neonatal surgery is risky and the repair effect is not very good. However, too late will bring bad psychological influence to children and parents. The main surgical methods of cleft lip are rotary propulsion, lower triangular flap and straight line method. Rotary propulsion is widely used in the world, and the application scope of straight line method is too narrow. In addition to functional cleft lip repair, it is now advocated to correct cleft lip nose deformity while repairing cleft lip. Due to various objective factors, it is often necessary to perform multiple cleft lip operations to achieve the best surgical results.
Prevention:
Pregnant women eat more folic acid to reduce the congenital defects of baby rabbit lips.
Let the doctor see the B-ultrasound. It is generally unlikely.
Question 2: What do rabbit lips look like? 50 points) Cleft lip can be divided into:
1. Unilateral cleft lip can be divided into incomplete type and complete type.
2. Bilateral cleft lip has incomplete type, complete type and mixed type, that is, one side is complete type and the other side is incomplete type.
(2) According to the crack degree, it is divided into:
First-degree cleft lip is limited to red cleft lip,
The second degree cleft lip is upper cleft lip, which does not reach the bottom of nose, and the shallow second degree cleft lip does not exceed1/2 of lip height; The second depth is 65438+ 0/2 of the crack height on the lip.
The third degree cleft lip is the upper lip, and the bottom of the nose is completely cracked.
Cryptic fissure means that although the skin and mucosa are not cracked, they lack muscle layer.
clinical picture
The main manifestation of cleft lip is upper lip cracking, which is divided into three degrees according to the location and degree of cracking.
1. First-degree cleft lip is just red lip.
2. The second degree is that the fissure exceeds the red lip but does not reach the bottom of the nose.
3. The third degree is that the tear is completely split from the red lip to the bottom of the nose. The first two kinds are also called incomplete cleft lip, and the last one is called complete cleft lip.
Question 3: What does rabbit lips mean? Before birth, due to incomplete development, the upper lip split from the middle to the place under the nose.
Because it looks like a rabbit's three-petal mouth, it is called rabbit's lip.
The degree of tearing is different, and the situation is different. It can be stitched, which generally has little effect on the future, except that there will be a scar between the nose and lips.
Question 4: What do you mean by rabbit lips? The doctor said that rabbit lip is a congenital defect, medically known as cleft lip or cleft lip and palate. There are more men than women. Cleft lip and palate can be unilateral or bilateral, complete or incomplete. This defect not only affects appearance, but also affects pronunciation, swallowing and sucking milk. The disease is a polygenic genetic disease, which is closely related to internal and external environmental factors. According to the survey, there are 1 rabbit lip babies in every 700 newborn babies.
Question 5: What's wrong with rabbit lips? Rabbit lip is also called cleft lip and palate. Cleft lip and palate is the most common congenital malformation in oral and maxillofacial region, with an average of 65,438+0 babies born with cleft lip and palate. Cleft lip and palate not only seriously affects facial beauty, but also directly affects development because of the communication between oral cavity and nasal cavity, which often leads to upper respiratory tract infection and otitis media. Children's difficulty in sucking milk leads to obvious malnutrition and causes serious psychological trauma to children and parents.
Etiology, this congenital malformation is mainly the fetal facial development disorder caused by some pathogenic factors during the fourth week of pregnancy 10 week. At present, medicine believes that the possible pathogenic factors are: ① genetic factors: some children's immediate or collateral relatives have similar deformities. About 20% children with cleft lip and palate can be found to have a genetic history. ② Infection and injury: The mother was infected with virus in the early pregnancy (about 2 months), such as influenza, rubella or some kind of injury, which may be the cause of cleft lip and palate. My mother suffered from chronic diseases during pregnancy, such as anemia, diabetes and severe malnutrition. ④ Taking certain drugs during pregnancy: such as sedatives, antiepileptic drugs and hormonal drugs. ⑤ My mother was indirectly exposed to high-dose X-rays during pregnancy. Therefore, the key to prevent cleft lip and palate lies in the early pregnancy.
Question 6: What is the cause of harelip? Cleavage, commonly known as rabbit lip, notch and notch, is a common congenital malformation in oral and maxillofacial region. The incidence rate is about 1.82‰, and the number of patients in China exceeds1.7000, which is a multifactorial genetic disease.
Etiology:

① Genetic factors: Genetic studies have proved that this disease is polygenic, and 20-30% of patients have positive genetic factors. We often see similar deformities in patients' relatives.
② Environmental factors: vitamin deficiency during pregnancy, mother's infection with virus during pregnancy, exposure to X-rays, hormones or anti-tumor drugs, antihistamines, alcohol and tobacco, etc. , may cause a series of genetic mutations and other distortions.

Prevention:
Pregnant women eat folic acid to reduce rabbit baby's lips.
Pregnant women eat more folic acid to reduce the congenital defects of baby rabbit lips.
Experts found that if women eat folic acid during pregnancy, it will reduce the birth defects of infants with cleft lip and palate.
The researchers say that if pregnant women have children born by family members, then additional supplements may help women.
Experts have long known that folic acid can reduce the risk of brain injury and spina bifida in infants.
Recent studies have also shown that folic acid can reduce the risk of Down syndrome and leukemia in infants.
At present, doctors advise pregnant women to take folic acid supplements in the first three months of pregnancy.
Broccoli is a dish containing a lot of folic acid.
Related to genes
The researchers said that their research showed that women's intake of extra folic acid in early pregnancy could help reduce the birth defects of infants with cleft lip and palate.
However, the researchers said that further research is needed to confirm this finding.
Cleft lip and cleft jaw are common congenital defects, which occur in at least one in every 1000 newborns in Britain.
This happens in the early pregnancy, and the maxilla of the fetal mouth fails to join normally.
Babies with cleft lip need multiple operations and speech therapy to remedy this congenital defect.
This disease is also closely related to genes. If a baby's brother or sister also has this congenital defect, then the baby is 30 to 40 times more likely to have this defect than other babies.
Question 7: What causes cleft lip in rabbits? Refers to congenital upper cleft lip, with unilateral cleft and bilateral cleft. Because it looks like rabbit lips, it is also commonly known as "rabbit lips" among the people. Cleft lip is a congenital defect and the most common congenital malformation in oral and maxillofacial region. It is usually associated with cleft palate, with more males than females. This defect not only affects appearance, but also affects pronunciation, swallowing and sucking milk. The disease is a polygenic genetic disease, which is closely related to internal and external environmental factors. According to the survey, there are 1 cleft lip babies in every 700 newborns. Mastering some necessary scientific knowledge is very important for preventing and reducing the occurrence of congenital cleft lip and palate. 1 genetic factors: there are similar deformities in their immediate or collateral relatives. Adverse effects of pregnant women during pregnancy. ① Diseases: Statistics of some clinical cases prove that some diseases suffered by women during pregnancy are the main causes of congenital cleft lip and palate. For example, a cold, especially in the first three months of pregnancy, when the mother is sick, may cause fetal palatal development defects. ② Improper medication: The side effects of various drugs are an important factor leading to fetal malformation. Studies have proved that taking epileptic drugs in early pregnancy and taking a large amount of vitamin A during pregnancy can cause congenital cleft lip and palate. Bad habits: Smoking, drinking or taking alcoholic beverages during pregnancy also make some fetuses innocent victims. ④ Environmental pollution: Close contact with pesticides and other chemicals, toxic substances, excessive exposure to radiation or long-term computer operation in the first trimester can easily lead to congenital cleft lip and palate. Therefore, some experts suggest that you should avoid working in front of the computer for a long time during pregnancy.
