What is the cause of rabbit lip? Genetic research also believes that cleft lip deformity has a certain relationship with heredity. In the first three months of pregnancy, when the maternal physiological state is violated or disturbed, rabbit lips may also appear. Let's first understand what is the cause of harelip.
What is the reason of rabbit lip 1 1? Genetic factors.
Patients with cleft lip can find similar deformities in their immediate or collateral relatives, so it is considered that cleft lip deformity is related to heredity. Genetic research also believes that cleft lip is a polygenic genetic disease.
2. Environmental factors
In the first three months of pregnancy, when the maternal physiological state is violated or disturbed, it may affect the growth and development of the embryonic maxillofacial region. Such as nutritional deficiency, infection, drug factors, physical injury and alcohol and tobacco.
What is rabbit lips?
Rabbit lip, medically called cleft lip, and a similar deformity called cleft palate are common congenital deformities in oral and maxillofacial region, which are manifested as upper lip or cleft palate respectively.
What are the treatment methods of rabbit lip?
1, operation time
It is generally believed that unilateral cleft lip surgery is suitable for about three to six months, while bilateral cleft lip is a little later. The basic conditions for children to adapt to surgery are: general health, no upper respiratory tract infection, and no infection in local and surrounding tissues.
2. Surgical methods for cleft lip repair.
The basic steps of cleft lip repair surgery are fixed-point design, incision, repair and continuous reconstruction of cleft lip nasal muscles and skin suture. There are many fixed-point design methods, and different medical centers and doctors can adopt different surgical methods according to the specific situation of cleft lip.
3. Postoperative treatment
The upper lip was fixed with steel wire lip arch tape for 2 weeks to prevent the wound from cracking and reduce scar healing. After the child was awake from basic anesthesia, the elbow joints were fixed with splint bandage to avoid scratching the wound and reduce the labial arch. Gently wipe the lip wound with 3% hydrogen peroxide and iodophor to prevent scab coverage and affect wound healing. The wound was taken out in 5-7 days.
4. Sequential therapy after operation
Although the cleft lip was repaired in infancy, with the growth and development, the nose and lips will still have different degrees of deformity, which is called secondary deformity after cleft lip surgery and needs further plastic surgery before school. Patients with alveolar bone fracture need bone graft repair at the age of 12, and those with secondary jaw deformity need orthognathic surgery in adulthood to further improve facial morphology and occlusal function.
What are the precautions for rabbit lips?
1, pre-pregnancy examination
Rabbit lip is a polygenic genetic disease, so a comprehensive and cautious pre-pregnancy examination must be carried out before pregnancy. If one or both of them have this disease or have a family history, the probability of fetal illness will be high.
2. Clean pregnancy
Mother's infection with virus, taking some drugs, exposure to X-rays and lack of oxygen during pregnancy may all cause gene mutation, leading to baby's harelip. Alcoholism and smoking (including second-hand smoke) are both invisible killers that cause baby rabbits' lips.
3. Pregnant women during pregnancy
We should avoid partial eclipse, ensure adequate intake of vitamins B, C, D, calcium, iron and phosphorus, keep a calm mind and avoid mental stress. Don't take antineoplastic drugs, anticonvulsants, histamine drugs, morning sickness keminjing and some sleeping pills.
What are the clinical manifestations of rabbit lips?
The main manifestation of cleft lip is upper cleft lip. It can be divided into three degrees according to the location and degree of cracks. Once, rabbit lips were just red lips. The second degree is that the fissure exceeds the red lip but does not reach the bottom of the nose. 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.
What is the syndrome differentiation and treatment of rabbit lip?
1, common cold's lip invasion syndrome
More common in autumn and winter. The lip muscle membrane is chapped, scabbed and bleeding, which hinders diet. Dry skin, dry throat and thirst, short and red urine, dry stool, dry tongue and rapid pulse. Phragmites communis, Trichosanthes root, Ophiopogon japonicus and Sangxing decoction.
2. Syndrome of stomach heat hurting body fluid
Dry, shriveled and swollen lips, accompanied by thirst, bad breath, constipation, yellow urine, red tongue, thick yellow fur and slippery pulse. Clearing stomach and nourishing yin.
3. Deficiency of fire and lip syndrome
Red lips, wrinkled cheeks, red cheekbones, fever of hands and feet, hot flashes, night sweats, insomnia, yellow urine, constipation, red tongue, little fur and rapid pulse. Nourishing yin and reducing fire. White texture yellow soup Polygonatum odoratum, Dendrobium, Trichosanthes root.
What are the examinations of rabbit lips?
1, comparative examination process of temporomandibular joint
Put the little finger of both hands into the external auditory canal, touch it forward, put the thumb of both hands in front of the tragus on both sides respectively, and ask the patient to open his mouth and close his mouth, and check the movement of condyle, whether there is a click, rubbing sound, etc.
2. Maxillofacial examination process:
Voice and auscultation examination, check the nasal sound of cleft palate patients; The lump at the base of the tongue may have an "olive sound". Hemangioma can be heard locally with obvious blowing noise.
What are the causes of cleft lip in rabbits? 2 1. The cause of cleft lip is nutritional factors.
Vomiting and partial eclipse during pregnancy will affect the intake of nutrients and cause vitamin deficiency. In animal experiments, when pregnant mice are fed with foods lacking vitamins A and E, the chances of giving birth to young mice with cleft lip (cleft palate) are very high.
2. The cause of cleft lip is drug factor.
Some drugs can affect embryonic development through the placental barrier, such as sleeping pills, antiallergic drugs, phenytoin, adrenocortical hormone, cyclophosphamide and other drugs, which can all lead to fetal malformation.
3. The cause of cleft lip has endocrine influence.
Experiments show that pregnant rats are more likely to give birth to young rats with cleft lip and palate by injecting adrenocortical hormone every day at 9- 1 1 day after pregnancy. Therefore, if the early pregnancy (within 8 weeks) of pregnant women due to physical, mental, injury and other reasons, the secretion of adrenocortical hormone in the body increases, it will also lead to congenital malformation of the baby.
4. The cause of cleft lip is sunburn.
Lips, like skin, will be sunburned by the sun. Yes, lips will peel off, and sunburned lips will be very painful. Applying aloe vera to lips after sun exposure can relieve lip pain and help accelerate healing. You can also wear lip balm with a sun protection index of at least 15.
How to prevent cleft lip in winter
1, drink plenty of water in winter to prevent cleft lip.
It is best to drink 8- 10 glass of water every day, and the lips are the primary organ that reflects the lack of water in the body. The more water you drink, the less likely your lips will be chapped.
2. Prevent cleft lip. Don't lick or tear open your mouth in winter.
These two bad habits will only make your lips drier and even cause infection or cold sores. When your lips are chapped, resist the urge to lick or tear the skin of your mouth.
3. To prevent cleft lip in winter, exfoliate.
Remove dead skin cutin from lips before applying ointment or other skin care products. Removing dead skin can expose new skin of lips and accelerate the healing of lips. Don't wipe your lips too rudely ―― it will only make your lips worse. Gently massage your lips. Wipe with salt or sugar. Take a small amount of salt or sugar and gently massage in circles on your lips to remove dead skin. After the massage, you will feel your lips look brand-new. Use an exfoliating brush. The simplest exfoliating brush is your toothbrush! But make sure the toothbrush is clean. You can also use other small brushes to gently wipe the lips in circles to wipe off the dead skin on your lips. Don't use exfoliating products made of soap. Facial cleanser containing particles or exfoliating products containing soap will make lips drier.
4. Use ointment to prevent cleft lip in winter.
Pay attention to the over-the-counter ointment or lip balm you use every day to relieve chapped lips, because many ointments or lip balm contain ingredients that make your lips dehydrated, and long-term use will make your lips drier and drier. Use lip balm rich in natural moisturizing ingredients such as beeswax, shea butter, coconut oil and sweet almond oil. Don't buy a bunch of lip balm that you can't pronounce. Natural ointments such as vitamin E ointment and glycerin ointment are equally effective.
