Cleft palate is more common and can occur alone or in combination with cleft lip. Cleft palate is not only a soft tissue deformity, but most patients with cleft palate may also have varying degrees of bone defects and deformities, which are far more severe than cleft lip in terms of sucking, eating and speech and other physical dysfunctions. As a result of jaw growth disorders, the middle of the face often collapses, resulting in a disc-shaped face and a misaligned bite (often antimandibular or open jaw) in severe cases. Therefore, the various physiological dysfunctions caused by cleft palate, especially speech dysfunction and dental malocclusion, have adverse effects on patients’ daily life, study and work, and also tend to cause psychological disorders in patients. So, how to effectively prevent cleft palate? The following are measures to prevent cleft palate: Emotional stability: When pregnant women have bad emotions such as worry, anxiety, irritability and fear, adrenocorticotropic hormones may hinder the fusion of certain tissues of the embryo, causing fetal cleft lip or cleft palate; Nutritional balance: The mother is the first source of nutrition for the fetus. A balanced and diverse diet is very important during pregnancy. Everything you eat and drink during pregnancy can have an impact on the baby. Eat plenty of vegetables and fresh fruit and less sugary, salty and processed foods; avoid colds: It has been found that many mothers of children with cleft lip and palate have had colds during the first trimester, which is an important factor in causing cleft lip and palate; protect against viruses: Women during pregnancy should pay special attention to preventing viral infections such as rubella; stay away from radiation: Young couples should avoid exposure to radiation for 3 months before deciding to become pregnant Many pregnant women now work normally until they give birth, and many offices are open places, full of computers and dozens of cell phones used at the same time, which is very detrimental to the health of the fetus; Quit smoking and drinking: a Mexican study showed that “cleft lip and palate” is due to the fact that the development of the upper lip and palate of the baby during the embryonic period is impaired. The development of the upper lip and palate of the baby is blocked during the embryonic period, and the abnormal development of the embryo due to long-term smoking and alcohol abuse by pregnant women is one of the reasons; master the timing of childbirth: doctors said that parents under 20 and over 35 years old have the greatest possibility of producing deformed children, because under 20 years old is not fully mature, and over 35 years old has begun to age, therefore, women are well-known between 25 and 30 years old to have children; pay attention to the wedding and maternity checkups: well-known before marriage Famous screening through marriage examinations to detect genetic diseases such as cleft lip and palate. In addition, an experienced physician at 20 to 24 weeks of fetal age can tell from an ultrasound examination if the fetus has more obvious malformations such as limb stumps.
