Understanding the Real Differences
Silicone and saline implants have been in continuous clinical use for decades. Both are FDA-approved, both produce excellent results in appropriate patients, and both are used at this practice. The debate over which is "better" misses the point — the right implant type is the one best matched to your anatomy, starting breast tissue, and what matters most to you.
The most important honest statement about this comparison: for patients with adequate native breast tissue to cover the implant, most patients cannot reliably tell the difference by feel when the implant is properly placed beneath the muscle. The differences become more significant at extremes — very thin patients with minimal tissue, or very large implant volumes — and in those circumstances the choice matters more.
Side-by-Side Comparison
| Factor | Silicone Gel | Saline |
|---|---|---|
| Fill Material | Cohesive silicone gel (cross-linked) | Sterile saltwater solution |
| Natural Feel | More closely mimics breast tissue; softness varies by gel cohesivity | Firmer; can feel "water balloon-like" in thin patients |
| Rippling / Palpability | Less rippling; less palpable through thin tissue | More prone to rippling and edge palpability, especially lateral pole |
| Rupture Detection | Silent rupture — requires MRI every 2–3 years to screen | Visible deflation within days — no imaging required |
| Rupture Consequence | Gel remains largely contained; no health risk from leakage | Saline absorbed harmlessly; cosmetic change only |
| Incision Size | Pre-filled — requires larger incision (~4–5 cm) | Filled after placement — smaller incision possible (~3 cm) |
| Minimum FDA Age | 22 years for cosmetic augmentation | 18 years for cosmetic augmentation |
| Implant Brands (used here) | Motiva, Allergan, Mentor | Allergan, Mentor |
| Relative Cost | Slightly higher implant cost (~$1,000–$1,500 more) | Lower implant cost |
| Revision if Ruptured | Capsulectomy + new implant placement | Straightforward replacement, often outpatient |
Implant Brands: Motiva, Allergan, and Mentor
This practice offers silicone implants from three manufacturers: Motiva, Allergan, and Mentor. Each has a distinct gel formulation, surface technology, and warranty program. Motiva implants feature a nano-textured surface (SilkSurface) that provides adherence benefits of a textured surface without the risks associated with macro-textured implants. Allergan and Mentor offer the most extensive long-term safety data given their decades in clinical use.
Note on textured implants: Macro-textured breast implants (a specific surface type used by some manufacturers) have been associated with Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL), a rare but real condition. Dr. Rafizadeh does not use macro-textured implants. All implants placed at this practice use smooth or nano-textured surfaces.
The choice between Motiva, Allergan, and Mentor is made in consultation based on the patient's anatomy, desired result, and implant profile requirements. Each brand has relative strengths in different scenarios — a detailed discussion at consultation determines which is optimal for each patient.

- Thin body habitus with minimal native breast tissue to cover implant
- Small starting breast size (A cup or smaller) — less tissue to hide edges
- Under-muscle placement planned (adds more coverage)
- Concerned about rippling or palpable edges
- Prioritizing the most natural feel and movement
- Patient is 22 or older (FDA cosmetic augmentation minimum)
- Adequate native breast tissue (B cup or larger before augmentation)
- Patient age 18–21 (silicone not FDA-approved for cosmetic use)
- Prefers the ability to detect rupture without imaging
- Cost is a primary consideration
- Values the smaller incision option
- Comfortable accepting slightly firmer feel
Rippling — visible or palpable ripples along the edge of the implant — is one of the most common reasons patients revisit the silicone-versus-saline decision. It is more likely with saline implants, thin native tissue, and over-the-muscle placement, and much less likely with cohesive silicone gel under the muscle. If rippling is a concern for you, see Breast Implant Rippling: Causes and Fixes, which covers how implant type, placement, and fat grafting each play a role.
"For a 34A patient who is 5'4" and 125 lbs, silicone is almost always the right answer — the tissue coverage is minimal and the difference in feel and rippling is real and visible. For a patient who's already a full B, the choice is much less consequential and comes down to personal preference."

Teardrop vs. Round Implants: Does Shape Matter?
Round implants are the most commonly used shape in cosmetic breast augmentation. They provide fullness in the upper pole — the upper portion of the breast — which many patients desire. Because they are symmetric, rotation does not affect the result.
Anatomical ("teardrop") implants are shaped to mimic natural breast anatomy — more volume in the lower pole, less in the upper. They were developed with the goal of a more natural appearance, but studies consistently show that patients and observers cannot reliably distinguish the results of round versus anatomical implants when both are correctly placed. In addition, anatomical implants can rotate after surgery, causing visible shape distortion — a complication that round implants cannot produce.
For most cosmetic breast augmentation patients at this practice, round implants are used. Anatomical implants are considered in specific reconstructive and revision scenarios where anatomical shaping is technically advantageous.
Long-Term Monitoring: What Each Requires
All breast implants require long-term monitoring, but the method differs by type. The FDA recommends MRI screening for silicone implants every 2–3 years beginning 5–6 years after placement. This is not routinely required for saline implants because saline rupture is immediately and obviously apparent — the deflation is visible within days.
Neither implant type is designed to last a lifetime, though many patients keep their implants for 15–20+ years without issues. The decision to replace implants is driven by symptoms, rupture, or patient preference — not a fixed replacement timeline. For more on this, see How Long Do Breast Implants Last?
Breast Implant Illness (BII): Some patients report systemic symptoms they associate with their silicone implants. This is an area of ongoing research. The FDA recognizes BII as a real phenomenon reported by patients; the scientific evidence on causation is not yet definitive. Patients with concerns about BII should discuss them openly at consultation.
