The time of hospitalization necessary for the realization of this gesture is from 24 to 48 o'clock.

After 2 weeks of expectation, the surgeon begins in consultation, the inflatings by injecting, through the skin, physiological serum in the valve of inflating of the expander. He begins again this operation every week and the prosthesis is so going to increase by volume and to distend the placed skin near the hurt.

Two great nevi of the back. Prostheses placing are implants foreseen to be inflated until 250cc but they have been overflated to obtain a maximal expansion

When the expandeur is filled, a new intervention allows to remove it, and with it a surface of naevus equivalent in the supplementary surface of healthy skin obtained by distension. This supplementary earning skin is used to cover the loss of substance.
