In short. Alar base reduction carries risks that belong to the nostril margin and the scar line rather than to nose surgery in general. Notching, pinching and a tethered rim, asymmetry, a scar that widens or holds colour, and distortion of the nostril opening are the main ones, and most are judged late, once the swelling has gone.
Key points
- The specific risks sit at the rim, the sill and the scar line.
- Notching is the commonest complication specific to alar base reduction.
- Removing too much tissue causes pinching and a tethered rim.
- Perfect symmetry is not realistic; an early visible difference can become unnoticeable.
- A scar is judged at a year, not at three months.
Where these complications sit
The risks that belong to this operation are not the risks of nose surgery in general. They cluster at the rim, the edge of the opening, and the line across the base or the sill. They are usually visible before they are felt, and most of them are judged late, once the swelling has gone and the scar has stopped changing. The rim is examined before anything is planned, because an edge that is already irregular is a reason to plan differently.
Notching and an irregular rim
Notching is a small step or dip in the curve of the nostril where tissue was removed. It happens at the margin, and it is the commonest complication specific to this operation. A minor notch reads as part of the nostril edge; a larger one is seen from the front and can be felt with a fingertip.
Why does the rim become pinched or tethered?
Take too much tissue, or place the line so that the maturing scar pulls the rim, and the nostril loses its natural curve. The edge appears drawn inward, sometimes with a small fold where the skin is tethered to the tissue beneath. This is where over-narrowing shows first, and it is the outcome patients most often describe as pinched rather than as a complication.
Can the two sides be made symmetrical?
Perfect symmetry is not a realistic target, because the two sides rarely start symmetrical and they heal at slightly different rates. The realistic result is that a difference obvious immediately after the operation becomes one other people do not notice. A difference still obvious at a year, or one that appears on a side treated differently from the other, is worth raising rather than accepting.
When should a scar be judged?
The line can widen, thicken, or stay red far longer than expected. Placement and skin behaviour decide most of this. A line that crosses the sill is the most exposed, and skin that tans easily holds colour longest. This is a maturation outcome rather than a surgical error, so a judgement about the scar belongs at a year and not at three months.
How the nostril opening changes
Narrowing the rim changes the shape of the opening as a side effect. A round opening can become more oval, and one that was already small can become slit-like. Where the underlying shape is set by cartilage rather than by skin, a plan on the margin cannot rebuild it.
| Complication | What it looks like | Why it happens | When it is judged |
|---|---|---|---|
| Notching | A step or dip in the curve of the rim | Tissue is removed at the margin | Once the swelling has gone |
| Pinching | The edge drawn inward | Too much tissue is taken, or a scar pulls the rim | As the scar matures |
| Tethered rim | The rim pulled down to the tissue beneath | The maturing scar pulls the edge | As the scar matures |
| Asymmetry | A difference obvious straight after surgery | The sides start differently and heal at different rates | At a year if still obvious |
| Widened scar | A line that widens, thickens or stays red | Placement and skin behaviour | At a year |
| Distorted opening | A round opening becoming oval, or a small one slit-like | Narrowing the rim changes the opening | As a side effect of the change |
Which findings need assessment rather than patience?
A notch, step or fold at the rim that you can feel as well as see needs assessment. So does a difference between the two sides that is widening rather than settling. A line that is thickening, itching or spreading beyond the border of the original scar also needs review.

Frequently asked questions
What does notching at the nostril edge look like?
A small step or dip in the curve of the rim, where tissue was removed and the edge no longer runs smoothly. A minor one reads as part of the nostril; a larger one is seen from the front and can be felt with a fingertip. It is usually noticed once the swelling has left and the line has softened enough to show the shape beneath.
How would I notice that the rim has become tethered?
The edge looks drawn inward rather than curved, and there may be a small fold where the skin is pulled down to the tissue beneath it. It can appear as a flattening of the rim on one side, and it is often most obvious in the front view. Pulling on the nostril does not correct it, which is what separates it from swelling.
A scar that widened: was that a mistake or a healing outcome?
Usually a healing outcome. Placement and skin behaviour decide most of it, and skin that tans easily or thickens readily does this more often. That does not make it acceptable to the person living with it, but it does mean the answer is a scar plan and possibly a revision rather than a claim that the operation was done badly.
Risks & Limitations
- The scar is the mechanism of this operation rather than a complication of it. It stays, and it matures over a year or more.
- Tissue removed from the alar base does not come back, so over-narrowing is difficult to correct.
- The nostril opening is part of the airway. Narrowing it can reduce breathing, and function comes before width.
- The two sides are rarely symmetrical to begin with, and a scar behaves worst in skin that tans easily.
When to Seek Care
- Difficulty breathing through the nose that is worsening rather than settling, or breathlessness at rest.
- Fever with spreading redness, warmth or discharge around the incision.
- Bleeding from the incision that does not stop with gentle pressure.
- A nostril that pulls inward when you breathe in, or an edge that is becoming notched or tethered.
