For children with phimosis, if before the age of three, phimosis has the possibility of self-healing and does not need surgery. If phimosis still exists after the age of three, circumcision is often considered for treatment. For children with redundant prepuce, if repeated balanitis or incarceration of prepuce occurs, circumcision is required. Common surgical methods include dorsal circumcision, sleeve circumcision, disposable circumcision device circumcision, laser circumcision, etc. Through prepuce operation, excessive prepuce can be effectively removed to fully expose the glans, which can reduce the occurrence of prepuce balanitis and is beneficial to children's health.
