In short. The base can only be narrowed by removing soft tissue, which means an incision and a permanent scar. What the operation reaches, and where it stops.
Key points
- That sentence is the operation in full.
- The change in width is small and real, the scar is permanent and usually inconspicuous but visible on close inspection, and the two cannot be separated.
- Anyone considering this rung should be able to say which of the two they are buying, and be at peace with both.
The alar base is the one part of a nose that can be made genuinely narrower without an operation on bone, and it is also the one part where narrowing leaves a mark a patient can find for the rest of their life. Both of those things are true at once, and any honest account of the operation has to hold them together.
What the operation does
Making a base narrower means removing soft tissue and closing the gap. In practice that is a wedge taken from the ala, or a reduction at the sill, or a combination, and the choice depends on whether the width is in the outer wall of the nostril, in the floor of it, or in both. The incisions are placed in the crease where the ala meets the cheek, in the sill, or inside the nostril floor, so that the scar sits in a shadow line rather than across a surface. The tissue is then brought inward and closed, and the span across the nostrils is smaller by the amount removed.
What it cannot do
It does not change the width of the bony vault, which is above it and made of bone. It does not change the foundation: the maxilla underneath is not part of the operation, so a base that is wide because it sits on a broad midface moves inward over a foundation that has not changed. It cannot be repeated indefinitely, because each removal takes tissue that does not return. And it cannot be done without a scar, because the tissue has to be reached.
The trade is a few millimetres for a permanent mark
That sentence is the operation in full. The change in width is small and real, the scar is permanent and usually inconspicuous but visible on close inspection, and the two cannot be separated. Anyone considering this rung should be able to say which of the two they are buying, and be at peace with both.
Where the limits come from
Three things set the ceiling. The first is how much soft tissue there is to remove, which varies between people and is assessed by feel. The second is the width of the foundation, which does not move. The third is the airway, because bringing the ala inward narrows the nostril opening, and an opening that is already narrow becomes harder to breathe through. Where two of those three are unfavourable, the achievable change becomes very small, and an honest assessment will say so rather than proceed on the assumption that something can always be taken.
Stop and ask questions if
- You are promised a large narrowing without anyone discussing the foundation.
- Nobody has examined how your nostrils are shaped or how you breathe through them.
- The scar is described as invisible, or as something that will not be there later.
Where those scars sit and how they behave over the first year is covered in alar base surgery, scars and recovery.
Frequently asked questions
How much narrower can the alar base be made?
Usually a few millimetres rather than a visible transformation of the lower third. The limit is the amount of soft tissue available, the width of the foundation underneath and how much inward movement the nostril can take without pinching. A change of that size is often clearly visible in a front-view photograph, and it is not the kind of change that alters how a face is recognised. A specific figure belongs to your own examination.
Can alar base surgery change the shape of the nostrils as well as the width?
It often does, and that is part of the planning rather than a side effect. Removing tissue from the ala or lowering the sill changes the outline of the nostril opening, and where the nostril is already narrow or the sill is already low there is less room to work. The shape of the opening is one of the things examined beforehand precisely because the width cannot be changed without the shape changing with it.
What happens if the alar base is narrowed too far?
The nostril opening becomes pinched or slit-like, the base no longer matches the width of the face, and breathing through that side can become harder. Soft tissue that has been removed cannot be put back, and correction means adding tissue rather than removing it, which is a different and less predictable operation. This is the ceiling on the ladder, and it is the reason the change is deliberately modest.
Risks & Limitations
- Every treatment on this ladder carries risk, and no result can be guaranteed.
- Narrowing the alar base leaves a permanent scar. It matures and fades over about a year, and it does not disappear.
- Every operation that narrows a nose also narrows the passage through it, which is why the airway is examined before any plan is made.
- An over-narrowed nose is difficult to reverse, because correcting it means adding tissue rather than removing it.
When to Seek Care
- A change in vision, or severe eye pain, after any filler or operation on the nose — seek emergency care immediately.
- Rapidly increasing swelling, spreading redness, warmth or fever after treatment on the nose — seek care promptly.
- Bleeding from the nose that does not stop with gentle pressure, or new blockage that is worse on one side.
- A growth, or a lesion on the skin of the nose that bleeds or does not heal.
- After an injury, where the shape of the nose has changed or breathing is affected.
