Abstract
A key to successful breast reconstruction with a breast expander is the creation of an appropriately sized cavity at a proper position for implanting a breast prosthesis. With an appropriate cavity, it is normally unnecessary to add extra dissection in the replacement of the breast expander with a breast prosthesis. No addition of extra dissection reduces the risk of capsule contracture by hematoma and breast prosthesis malposition by unexpected movement. Moreover, accurate expansion with an expander could achieve an appropriate breast prosthesis choice without specialized equipment or seat-of-the-pants decision-making. However, one important point to remember is that an expander itself has a volume of over 60ml, depending on the type or size. The volume of the expander itself may produce serious asymmetry of the breasts.
