A child scalpel surgery is a child circumcision, which can usually be performed around the age of 1 to 10 years, but it is not definitively defined. Circumcision is a condition in which the head of the penis, in its natural state, is less exposed or cannot be exposed. The foreskin can cause the child to develop phimosis or ingrown prepuce. If phimosis recurs, surgery should be performed as soon as the child’s body can tolerate it, so as not to affect the development of the penis. Usually, surgery can be performed at one week of age or older. If a child develops simple phimosis, the need for surgery should be determined on a case-by-case basis. After a child develops, if the phimosis persists, the foreskin should be removed, including through circumcision, in order to avoid infections caused by the production of foreskin scales. When children undergo circumcision, they should choose regular hospitals to avoid improper operation that may affect the development of the penis.
