On this issue, there has been a debate in academic circles. Some people argue that cleft lip should be operated within one month after birth, even a few days after birth at the earliest. People who hold this view believe that the earlier the operation, the less psychological burden the mother has.

Neonatal upper lip tissue is thin, the body's resistance to the outside world is weak, and the reaction to surgery is relatively heavy. Coupled with the anesthesia problem of the operation, it will definitely increase the difficulty of the operation.

At present, most people at home and abroad advocate that it is a good time for children with cleft lip to have surgery within 6-8 months after birth. At this time, the child is gradually developing healthily and can withstand the blow of surgery; The front teeth have just erupted, and timely surgery can avoid the protrusion of the upper front teeth. Years of clinical practice have proved that surgery at this age will lead to a faster postoperative recovery, and the scars left after surgery will gradually decrease within a few months.

Some children are three or four years old and even go to preschool for surgery. At this time, because the lip tissue began to shrink gradually, the deformity of dentition and alveolar process was more difficult to correct. The postoperative effect is not as good as that of early operation. Doctors also found that these sick children showed some quirks, such as inferiority or loneliness. Therefore, it is very necessary for them to choose the timing of surgery.

It is very difficult for newborns with congenital palatal alignment to suck milk because they can't suck hard. When you can speak, because the soft palate is not moving smoothly, you can't close the nasopharyngeal cavity tightly, and your pronunciation is unclear and your nasal sound is serious, commonly known as "nasal sound". Parents of such sick children often ask for an operation as soon as possible.

Of course, the only way to treat cleft palate is surgical repair, which is difficult. Moreover, from the physiological and anatomical point of view, the baby's palate is not fully developed and is not suitable for premature surgery. At present, it is considered suitable for children aged three to preschool to have surgery, and the seasons are spring and autumn. After the operation, the pronunciation was mostly improved after deformity correction. After a period of language training, it will create certain favorable conditions for children to go to school and study.
