8 months post nose surgery — if you can feel the boundary between silicone and donor rib cartilage, is it worth worrying about?
2024. 6. 3.
An answer to a question about feeling the boundary and a ridge between donor rib cartilage and bridge silicone 8 months after surgery. Why an implant boundary sometimes shows, why it's a natural phenomenon distinct from inflammation, and what to do when it still bothers you.

Key points
- The boundary between two materials can be palpable — but if a ridge or movement newly became distinct 8 months later, the cause must be confirmed directly.
- It could be a change in tip height or skin thickness — but the absence of pain alone can't rule out material position or inflammation issues.
- Still, if it bothers or worries you too much, visiting the operating hospital to discuss with the attending doctor is recommended.
"I had surgery 8 months ago with donor rib cartilage and bridge silicone, and at some point the boundary between the two materials started feeling really noticeable. I feel a ridge, and when I touch the tip, the implant seems to move. There's no pain and no boundary line shows outside — could the donor rib cartilage have descended or detached inside?"
This was a question received in an actual consultation. It hadn't felt this noticeable right after surgery, yet over time the boundary ridge started feeling distinct — and the worry was whether something had gone wrong inside.
Based on the answer given to that question, this article organizes how to understand a palpable implant boundary.
01
Does a palpable implant boundary mean something went wrong?
The boundary between nasal implants can be palpable in some cases. Still, if the feel became distinct 8 months later and the implant seems to move, whether it's a normal change or a material-position/skin issue must be confirmed directly.
As in the questioner's case — with no pain and no boundary line visible externally — the palpable feel alone isn't grounds to conclude that material has descended or detached inside.
02
Why does the boundary become more palpable over time?
Most such cases are explained by changes like these.
- As time passes after surgery, the tip height lowers naturally.
- In that process, the boundary of the silicone sitting right above the tip starts showing.
- It's a natural phenomenon arising as tip skin thins and lowers slightly.
| Check item | Questioner's state | Meaning |
|---|---|---|
| Pain | None | Even without pain, material position, skin, and inflammation state need checking |
| Visible boundary line | Not visible | No externally revealed deformity |
| Palpable boundary/ridge | Became distinct over time | Don't conclude the cause — confirm at the operating hospital |
In short, the change itself — "it wasn't this palpable before but now feels severe" — is more likely the boundary becoming revealed in the natural change process of tip height and skin, rather than a signal that material detached. So it was answered that major worry probably isn't needed.
03
What if it still bothers me?
Most cases are explained as natural phenomena — but if the patient finds it too bothersome or worrying, visiting the operating hospital to discuss with the attending doctor is recommended, because confirming the state through direct examination is most certain.
If consulting the operating hospital is hard or another opinion is needed, the current state can be discussed via 1:1 video consultation — and what to check when revision surgery comes into consideration can be seen in the revision surgery guide.
04
Summary — knowing the cause changes the size of worry
If an implant boundary and ridge newly became distinct 8 months post-surgery, it could be a change in tip height or skin thickness — but the cause can't be confirmed remotely. Even without pain or external change, have material position and skin/inflammation state confirmed at the operating hospital — and if there's redness, warmth, pain, or skin color change, get examined without delay.
