In short. Cancer excision, trauma, infection and congenital absence all create nasal defects, and the cause changes the timing, the layers involved and the whole plan.
Key points
- What matters is depth, which layers are missing, what is exposed underneath, how much healthy skin remains nearby, and whether the wound bed can support a graft.
- Assessment answers those questions before any technique is chosen.
A nasal defect is missing tissue, but why it is missing matters as much as its size. Two defects of identical area can need completely different operations, because one was cut cleanly by a surgeon and the other was torn, burned or eaten away by infection.
Cancer excision
Skin cancer is the most common reason a nose is rebuilt. Basal cell carcinoma, squamous cell carcinoma and melanoma all favour the nose because it receives the most sun. The excision is planned first and the reconstruction second, and the resulting defect is a known shape with known margins. When the tumour is removed with margin control checked during the operation, reconstruction can usually proceed the same day.
Trauma
Trauma produces the least predictable defects. Bites, road injuries, falls and assault leave crushed, contaminated, irregular wounds in which the remaining tissue may look intact but have a compromised blood supply. The first operation is usually about cleaning and preserving, not rebuilding, because tissue that looks salvageable today may declare itself dead within a week. Reconstruction is planned only once the wound is clean and the surviving tissue is known.
Infection
Infection destroys cartilage quietly. A neglected abscess, a severe infection after piercing, or a systemic infection that settles in the nose can dissolve the support framework while leaving the skin apparently intact, and the nose then collapses into a saddle shape. The infection must be fully controlled and the tissue quiet before any graft is placed, because grafting into infected tissue reliably fails. That wait is not delay for its own sake; it is what makes the reconstruction hold.
Arrange assessment promptly if
- A sore on the nose bleeds, crusts, or fails to heal over several weeks, or a mole changes in size, colour or shape.
- The nose has collapsed or changed shape after an infection, a piercing, or a period of nasal drug use.
- Breathing through the nose has become difficult after any injury or infection, especially if it is worsening.
Congenital absence
Some people are born with part or all of the nose missing or underdeveloped, sometimes as part of a wider craniofacial condition. These are not wounds but absent anatomy, involving lining, support and cover together. Reconstruction is usually delayed until the facial skeleton has grown enough for the plan to remain valid, and it almost always needs more than one operation. Children are followed through growth rather than discharged after a single repair.
Why the cause changes the plan
Cause determines timing, cleanliness, how much tissue survives, and whether the problem is stable or still evolving. A cancer defect is clean and can be rebuilt early. A contaminated traumatic wound must wait. An infected nose must first be quiet. A congenital absence must wait for growth. Getting this sequence wrong wastes an operation and consumes tissue that cannot be replaced.
The defect is not only a hole
What matters is depth, which layers are missing, what is exposed underneath, how much healthy skin remains nearby, and whether the wound bed can support a graft. Assessment answers those questions before any technique is chosen.
Frequently asked questions
What causes a nasal defect?
Skin cancer is the most common reason a nose is rebuilt, because the nose receives the most sun. Trauma from bites, road injuries, falls and assault produces irregular contaminated defects. Infection can dissolve the supporting cartilage and leave a saddle nose. Some people are born with part or all of the nose absent.
Why does the cause change the timing of reconstruction?
Because a clean cancer excision can be rebuilt the same day, while a contaminated traumatic wound must be cleaned and left to settle first. An infected nose must be quiet before any graft is placed, and a congenital absence must wait until the facial skeleton has grown. Getting the sequence wrong wastes an operation.
Can a nose collapse after an infection?
Yes. Infection destroys cartilage quietly, so a neglected abscess or a severe infection after piercing can dissolve the support framework while the skin looks intact, and the nose then collapses into a saddle shape. The infection must be fully controlled before any graft is placed, because grafting into infected tissue reliably fails.
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.
