Yes, NUSS operation is a minor operation, that is, drilling two small holes in the chest wall, inserting an arched steel bar support, and taking it again in a few years. Twenty-four years old is a little old, so it is better to be younger. Of course, it is not impossible. I did it at the age of 29, and the effect is not as good as that of a child. If it's not serious, don't do it. Just eat fat!
