Environmental Factors: The following conditions occurring in the early stages of pregnancy (before the third month) may lead to cleft lip and palate in the baby:1. Viral infections: Such as upper respiratory tract infections in pregnant women, rubella, etc.
2. Drug effects: Such as taking antiepileptic drugs, cholesterol-like substances, antiallergic drugs, anticancer drugs, etc.
3. Endocrine factors: Psychological or traumatic factors, such as severe mental stress or physical injury.
4. Nutritional factors: Morning sickness, poor appetite, or picky eating during early pregnancy leading to deficiencies in vitamins D, folic acid, iron, calcium, etc.
5. Other factors: Such as exposure to X-rays, smoking, alcoholism, or hypoxia.
(II) Genetic Factors: A significant portion of cleft lip and palate is hereditary. If a direct family member has cleft lip, the risk of the offspring developing the condition is approximately 4%. The general probability of cleft lip and palate occurring in the first child is 1/600. If the first child has cleft lip and palate, the likelihood of the second child developing the condition is 3/100.
