Unilateral cleft lip flap repair

Cleft lip is commonly known as "rabbit lip", which refers to those with cracked upper lip, which is a congenital malformation. Cleft lip is the most common congenital malformation of the oral and maxillofacial region, often associated with cleft palate. Normal fetuses, after the fifth week, begin to gradually merge with each other to form a face, and deformities can occur if they fail to develop normally, including cleft lip. According to previous surveys, the prevalence of neonatal cleft lip and palate is about 1: 1, but the data are not the same everywhere. According to the results obtained by China's Birth Defects Detection Center from 1996 to 2000, 2 265 patients with cleft lip and palate were detected in more than 22,218,616 perinatal infants in 31 provinces and cities across the country, and the prevalence rate was 1.625: 1,000. . The above data shows that the prevalence of cleft lip and palate in China has an increasing trend, which is similar to the recent reports abroad. According to statistics, cleft lip and palate patients have a gender ratio of 1.5: 1, with more men than women.
