When a saline implant ruptures, your body absorbs the saline, the shell of the implant deflates, and the capsule around the implant begins to contract or tighten. The longer you leave the ruptured implant in, the tighter the capsule tends to get with time because it is tightening around a new smaller size. This can lead to visible rippling and distortion of the breast, as well as pain. If you remove the ruptured implant soon after the rupture, the capsule is not yet tight and replacing the implant is straightforward. The longer you wait, potentially more needs to be done during that surgery, such as removing the capsular contracture and releasing the scar tissue. The bottom line is there is no advantage to waiting.
