Southern Cross Invercargill Hospital - General Surgery

A silicone sack filled with either silicone gel or saline (salt water) is inserted underneath your chest muscle and skin. Before being inserted, the skin will sometimes need to be stretched to the required breast size. This is done by placing an empty bag where the implant will finally go, and gradually filling it with saline over weeks or months. The bag is then replaced by the implant in another operation.
