An absent breast may occur in both males and females. If only the nipple/areolar complex is missing, this condition is referred to as athelia, if the entire breast is missing, this condition is referrred to as amastia.
Reconstruction for amastia is delayed until a female has a fully developed breast on the other side. At this time, a tissue implant is placed in order to provide symmetry to the normal breast. In order to correct athelia, skin grafting can be performed to provide the color contrast of the areola; local tissue can be used to reconstruct the nipple. Alternatively, tattooing can be performed to create the areola.
