Patient: The penis is completely concealed. The penis is very small, just a little skin on the outside. It was like this at birth. Now one and a half years old. The test, complete anaplasia. The local doctor recommended surgery. I don’t know if this surgery will have any effect on the child’s future development. Do I need to wait until the child is a little older to have the surgery? Specialist: occult penis is a big concept. Anyone who meets the following 2 points 1. normal development of the penile corpus cavernosum 2. poorly revealed penis is considered to have an occult penis. The reason can be penile development problem, obesity, groin lump, post-circumcision scar, etc. The treatment plan taken for different reasons is different. If your child is obese and has severe fat accumulation around the root of the penis, then the surgery should be done with caution. If your child has a bird’s beak shaped penis and webbed skin present between the penis and scrotum, then surgery should be performed now. Surgery can be helpful in terms of penile appearance and penile development. Compared to a few years ago, there are now great advances in penis-forming surgery, especially in foreskin distribution, and the results are excellent, so don’t worry too much.
