In short. Silicone elastomer, ePTFE, and autologous cartilage behave differently in the nose. The material classes, their trade-offs, and how the choice is made.
Key points
- The right question is not which material is best, but what the nose needs.
- A small dorsal augmentation in thick skin and a full structural rebuild in scarred revision tissue are different problems with different answers.
- The material follows the analysis, not the other way round.
When a nose needs more height or projection than the patient’s own cartilage can supply, a surgeon chooses between an implant and a graft. The decision is about how a material behaves over decades, not about a brand. Three material classes are used in nasal surgery, and each has a distinct set of trade-offs that should be explained before the operation rather than discovered after it.
Silicone elastomer
Silicone elastomer is a solid, flexible polymer that is easy to shape, inexpensive, and simple to remove if needed. It does not bond to tissue, which is both its advantage and its problem: the capsule that forms around it can contract over years, thinning the skin and, in the worst case, allowing the implant to become visible or to extrude. When it is used, conservative height, careful pocket design, and long-term follow-up matter more than the material itself.
ePTFE
Expanded polytetrafluoroethylene is a porous polymer. Tissue grows into its surface, so it is less likely to migrate and less prone to the capsular contraction seen with silicone. That same tissue ingrowth makes it harder to remove cleanly, and it carries a higher rate of infection than silicone when it does become contaminated, because bacteria can colonise the porous structure. It can also show a visible edge under thin skin.
Autologous cartilage
Your own cartilage — septal, ear, or rib — is the material the nose tolerates best. It is living, it does not extrude, and infection is rare. The trade-offs are supply and behaviour: there may not be enough, harvesting adds a donor site, and grafts can resorb or, in the case of rib cartilage, warp. It is the material of choice for structural grafting and for revision, where the soft tissue is already compromised.
The material serves the plan
The right question is not which material is best, but what the nose needs. A small dorsal augmentation in thick skin and a full structural rebuild in scarred revision tissue are different problems with different answers. The material follows the analysis, not the other way round.
Honest limits of any material
- Every implant carries a lifetime risk of infection or extrusion; there is no permanent guarantee.
- No material stops the ageing of the skin over it, and thin skin may reveal edges.
- Removal or revision is a further operation with its own risks and its own recovery.
Whatever material is chosen, the operation is not finished when the sutures come out. The nose changes for a year afterwards, and the decision made in theatre is judged against that whole period, not against the first photographs taken a fortnight later.
Frequently asked questions
How does silicone elastomer behave in the nose?
It is a solid, flexible polymer that is easy to shape and simple to remove if needed, but it does not bond to tissue. The capsule that forms around it can contract over years, thinning the skin and, in the worst case, allowing the implant to become visible or to extrude.
What are the trade-offs of ePTFE?
Tissue grows into its porous surface, so it is less likely to migrate and less prone to the capsular contraction seen with silicone. That same ingrowth makes it harder to remove cleanly, it carries a higher rate of infection than silicone when contaminated, and it can show a visible edge under thin skin.
Is autologous cartilage the best material?
It is the material the nose tolerates best: living, it does not extrude, and infection is rare. The trade-offs are supply and behaviour, since there may not be enough, harvesting adds a donor site, and grafts can resorb or, in the case of rib cartilage, warp. It is the material of choice for structural grafting and revision.
Risks & Limitations
- Bruising and swelling lasting weeks; after bone surgery, months pass before the final result is visible.
- Scars are permanent. They mature and fade over 6–12 months but never disappear.
- Numbness or altered sensation, which may be temporary or, after bone or nerve work, lasting.
- Asymmetry, under-correction or over-correction; final assessment is made at 6–12 months.
- Infection, bleeding or haematoma, which may need drainage or antibiotics.
- Breathing changes after nasal surgery, which may be temporary or require further treatment.
- Revision surgery carries higher risk and is less predictable than a first operation.
When to Seek Care
- Difficulty breathing or shortness of breath — seek emergency care immediately.
- Rapidly expanding swelling, or a tense, painful, tight area.
- Fever above 38 °C, spreading redness, warmth or pus.
- Bleeding that does not stop with gentle pressure.
- Any sudden change in vision after facial surgery or a facial injection.
