According to the survey, the prevalence of cleft lip and palate in newborns is about 1:1000, but the information is not exactly the same everywhere. According to the results obtained by our birth defect detection center from 1996 to 2000, 2265 cases of cleft lip and palate were detected among more than 22,186,160,000 perinatal babies in 31 provinces and cities, and their prevalence rate was 1.625:1,000. the above information shows that the prevalence of cleft lip and palate in China is on the rise. According to statistics, the ratio of male to female cleft lip and palate patients is 1.5:1, with more males than females. The onset of the disease is related to genetic factors and environmental and other factors. Cleft lip is a complex embryonic developmental malformation involving the development of skin, mucosa, muscle, cartilage and bone, which can be repaired early (>5kg and >10g/dL hemoglobin in affected children). However, a thorough repair of secondary deformities is usually required in adults for the following reasons: 1. The child is too small at the time of repair, and some deformities such as cartilage have not yet manifested. 2. The repair surgery is not fine enough when the child is small, and the small errors become obvious when the child grows up. 3, local scar proliferation is obvious. 4.It is a kind of embryonic developmental malformation itself, which needs to be repaired several times. Repair goals: to completely free and reset the displaced tissues, reset the function of orbicularis oris muscle, recreate the human middle concavity and human middle ridge, make the sulcus line on the lip arch continuous, reset the collapsed nasal cartilage, and make the shape of nasal columella, nasal base and nostril complete. Repair content: including upper lip scar, asymmetrical thickness of the lip, asymmetrical human middle, too long upper lip, too tight upper lip, incised cleft or whistle-like deformity of the lip, uneven lip arch, nasal wing collapse, and too small nostril.
