What to check before spread-nose surgery — why reducing the alae alone isn’t enough
2025. 11. 23.
A spread nose isn’t only a matter of alar width. Organized how cartilage shape·skin thickness·the movement of the levator labii superioris alaeque nasi are separated as causes, and why support structure and facial balance are designed together.

Key points
- A spread nose isn’t only a matter of alar width — it’s a problem where cartilage shape, skin thickness, subcutaneous fat distribution, and the force of muscles that move when smiling act in combination.
- When the nose widens left and right when smiling, the levator labii superioris alaeque nasi is often overactive — reducing only the alae may let it spread again over time.
- Even after correcting the cause, a weak internal structure can widen again — so the support structure holding the tip and overall facial balance are designed together.
“Can’t I just reduce the alae?”
This is a question often heard first in spread-nose consultations. From outside it looks like a problem of wide nostrils, but in reality a fairly complex structure and intertwined causes are involved. Over 20 years of focusing on nose surgery and meeting many spread-nose patients, what I’ve felt is that rather than just refining shape, the cause that made the nose spread must be found and corrected.
This article organizes why nasal spreading occurs and what to check before surgery.
01
Why isn’t reducing the alae alone enough for a spread nose?
A nose looking spread isn’t only because the nostrils are wide. It’s a problem where cartilage shape, skin thickness, subcutaneous fat distribution, and even the force of muscles that move when smiling act in combination — so surgical direction must be decided considering all these elements.
For example, in people whose nose widens left and right when smiling, the levator labii superioris alaeque nasi is often overactive. This muscle pulls the nose sideways making the alae spread. In such people, surgery that only reduces the alae may let it spread again over time.
So when correcting nasal spreading, even muscle movement is checked in detail. Correction that reduces the levator’s action proceeds in a way that minimizes incision. Only when muscle movement is stabilized can the nose not widen even when smiling, and approach a form where tip and alae continue naturally.
02
Can’t you just build the support structure without muscle correction?
Even if the cause of spreading is caught, a weak internal structure can widen again over time. Conversely, building only support structure while leaving the muscle’s excessive action leaves the cause behind. So the two are checked separately.
| What’s checked | Why it’s viewed |
|---|---|
| Muscle movement (levator labii superioris alaeque nasi) | To check whether it’s the force pulling the nose sideways when smiling |
| Tip support structure | Checked because a weak internal structure can widen again after correction |
| Skin thickness·cartilage state | Checked because thick skin or weak cartilage can loosen even with tying alone |
When support is needed, autologous rib cartilage is utilized to prop the tip structure. Rib cartilage is tissue harvested from one’s own body, so rejection is nearly absent and shape tends to be maintained over time. Especially for those with thick skin or weak existing cartilage, tying alone can loosen — a method erecting an internal supporting pillar is needed.
In spread-nose correction, designing so the form doesn’t collapse over time matters — and accordingly, the process of stably building internal structure is the core.
03
Won’t the result look awkward?
What matters when correcting nasal spreading is harmony. Approaching by unconditionally erecting the tip or greatly shrinking the alae can rather make the face awkward.
So before surgery the following are analyzed together.
- Facial proportion — looking not at the nose alone but the balance it occupies in the whole face.
- Philtrum angle — checking the relationship between the tip and around the lips.
- Distance between eyes and mouth — judging the nose width fitting the spacing between facial features.
Spread-nose correction is closer to a process of matching facial balance than a surgery fixing only the nose. Since it looks natural when each person’s different features come into harmony, the goal is finding a line where the nose doesn’t stand out yet anchors the face’s center — considering even face shape and expression.
Changes in actual correction cases can be confirmed in before-and-after photos.

Summary — the cause of spreading must be distinguished first
A spread nose is hard to view as a matter of alar width alone. Since the cause is complex — cartilage, skin, subcutaneous fat, and even muscles acting when smiling — distinguishing what makes the nose spread comes before deciding on a single method like alar reduction. After correcting the cause, a support structure is built so the form holds over time, and the scope is set to overall facial balance.
If curious whether your spreading is because of muscle or structure, you can get the change by expression checked directly in a 1:1 video consultation.
