Why revision is the time to reconsider
If you're already having surgery to remove or exchange your implants, you have a free choice about what goes back in — or whether anything does. Many people chose their original implant type years ago, when options or priorities were different. Revision is the moment to choose deliberately, based on how the two types actually behave.
How they differ
| Feature | Saline | Cohesive silicone |
|---|---|---|
| Feel | Firmer, can feel more like fluid | More natural, closer to breast tissue |
| Rippling | More prone to visible/palpable rippling | Resists rippling better |
| If it ruptures | Obvious deflation; saline harmlessly absorbed | Often a "silent" rupture with no signs |
| Detecting rupture | Visible — no imaging needed | Needs MRI or ultrasound surveillance |
| Incision | Can be filled after placement, so smaller incision | Pre-filled, so a slightly larger incision |
| Feel in thin tissue | Shows surface more | Smoother under thin tissue |
Why most revisions switch toward silicone
In practice, the most common revision switch is saline to cohesive silicone, for two reasons that matter a lot in revision patients:
- Feel — silicone feels more like natural breast tissue, which many patients prefer, especially after years with firmer saline.
- Less rippling — revision patients often have thinner tissue than at their first surgery, and silicone's resistance to rippling is a major advantage when coverage is limited.
The main trade-off to accept with silicone is the "silent rupture" issue: because a silicone rupture often has no symptoms, you take on a commitment to periodic imaging (MRI or ultrasound). For most patients, the better feel and reduced rippling outweigh this.
When saline still makes sense
Saline isn't obsolete. It can suit patients who specifically value that a rupture will be obvious without imaging, who prefer to avoid silicone for personal reasons, or where the smaller incision or fill-adjustability is an advantage. The right choice is individual — there's no universally "better" implant, only the better fit for your priorities and tissue.
The other option: no implant at all
Revision is also the moment some patients decide to remove implants without replacing them — see our pages on explant and en bloc and explant with or without a lift. With a lift and/or fat grafting to restore modest volume, an implant-free result is a real choice, not just a fallback. It's worth at least considering alongside the saline-versus-silicone question.
Making the decision
A good way to choose is to weigh four things: the feel you want, your tissue thickness (which drives rippling risk), your willingness to commit to imaging surveillance, and whether you'd consider going implant-free. An experienced revision surgeon will help you match these to the right option rather than defaulting to like-for-like — the individualised approach described on our what is breast revision page.
The bottom line: at revision you get a genuine choice. Most people move toward cohesive silicone for its natural feel and reduced rippling, accepting imaging surveillance in return — but saline and going implant-free are both legitimate options depending on your priorities.
