In short. Where a structural graft comes from, what each material class does, and why support is rebuilt before appearance in nasal reconstruction.
Key points
- Grafts taken from the patient's own body — autologous grafts — carry no risk of rejection, incorporate into the surrounding tissue, and behave like the tissue they replace.
- Alloplastic materials, meaning manufactured implants, have defined roles in selected revision situations, but carry higher risks of infection, extrusion and long-term complications, particularly in tissue that has been scarred, irradiated or previously infected.
A reconstructed nose needs a framework. Soft tissue alone will not hold a nasal shape, because every breath pulls inward on a nose that has lost its cartilage. Structural grafts are the answer, and where they come from is one of the most consequential decisions in the plan. Material classes are described below; no particular brand is recommended here.
Septal cartilage
Cartilage taken from the nasal septum is the first choice whenever enough of it remains. It is already the right tissue, it is flat and easy to shape into straight struts, and it is harvested through the same operative field, so there is no second donor site. The limitation is quantity: in a nose already operated on or injured, or destroyed by disease, there may not be enough left to spare.
Ear cartilage
Cartilage from the ear, usually the concha, is plentiful and can be taken through a small incision hidden behind the ear. It is curved, which makes it excellent for rebuilding the alar rim, but less suited to straight load-bearing struts unless it is shaped or laminated. The donor ear is left with a scar behind it and occasionally a change in contour. Harvest is generally well tolerated.
Rib cartilage
Rib cartilage provides the largest volume and the strongest struts, and is the usual choice when the septum is unusable or the defect large. It is harvested through an incision on the chest wall, which means a second surgical site, more discomfort, and a small risk of pneumothorax. Rib cartilage also tends to warp over time, so it is shaped in ways designed to limit that. The chest scar is permanent.
Autologous first, and why
Grafts taken from the patient's own body — autologous grafts — carry no risk of rejection, incorporate into the surrounding tissue, and behave like the tissue they replace. Alloplastic materials, meaning manufactured implants, have defined roles in selected revision situations, but carry higher risks of infection, extrusion and long-term complications, particularly in tissue that has been scarred, irradiated or previously infected.
What the graft actually does
A structural graft has three jobs. It holds the airway open against the pressure of breathing. It projects the nose away from the face, which is what makes it read as a nose in profile. And it gives the overlying skin something to drape over, so the cover layer has shape rather than a bulge.
Limits and long-term behaviour
Grafts can resorb, shift, warp or become infected, and a proportion of nasal reconstructions need a graft adjusted later. Cartilage is also felt as firm areas under thin skin, which most patients accept as the price of a stable framework. Nothing here restores a nose identical to the original, and the framework is assessed at six to twelve months.
Support is rebuilt before appearance, because without it there is no appearance worth refining.
Arrange review if
- The nose changes shape noticeably in the months after surgery, or the airway narrows on one side.
- A graft site becomes red, tender or discharges, or the skin over it thins and breaks open.
- You develop chest pain, breathlessness or a fever after rib cartilage harvest.
Frequently asked questions
Where does cartilage for nasal support come from?
The nasal septum is first choice whenever enough remains, because it is already the right tissue and needs no second donor site. Ear cartilage is plentiful and good for the curved alar rim. Rib cartilage gives the largest volume and strongest struts, but needs a chest incision and tends to warp over time.
Why are the patient’s own tissues preferred for support?
Because autologous grafts carry no risk of rejection, incorporate into surrounding tissue, and behave like the tissue they replace. Manufactured implants have defined roles in selected revision situations, but carry higher risks of infection, extrusion and long-term complications, particularly in tissue that has been scarred, irradiated or previously infected.

Risks & Limitations
- Nasal reconstruction is usually staged — two to four operations over months is normal, and the plan may change as healing progresses.
- A forehead flap leaves a permanent donor-site scar on the forehead and a temporary pedicle that looks unusual while it heals.
- Matching the colour and texture of facial skin is imperfect; a graft or flap usually stays slightly paler or thicker than the nose around it.
- Partial or complete failure of a graft or flap, which may require further surgery and a new plan.
- Narrowing of the airway, which can develop months or years later as scar contracts.
- Further revision is often needed to refine contour, thin a flap or release a narrowed airway.
- Altered or reduced sensation in the nose and, after a forehead flap, in the forehead.
- Final assessment is made at 6–12 months, never at the first dressing change.
When to Seek Care
- A flap or graft that turns dark, cold or black, or a wound that opens and does not close.
- Fever above 38 °C, or spreading redness, warmth or discharge around a wound.
- Difficulty breathing through the nose that worsens rather than settles.
- Bleeding that does not stop with gentle pressure.
- Severe pain, or a tense swelling under a flap or around the reconstruction.
