To Reduce Failure in Alar Surgery — The Difference Between External and Internal Incisions, and Why the Whole Structure Must Be Read Together
2025. 8. 29.
How external and internal incisions in alar reduction differ, and why reducing only the nostrils can fall short. Explains why the whole nasal structure should be diagnosed together for a bulbous nose or wide nostrils.
Key points
- Alar reduction broadly divides into external incision (narrows width along the outer alar line) and internal incision (incises inside the nostril to gather it inward).
- Wide nostrils don't mean simply reducing the nostrils solves it — a natural result is expected only when read together with the overall proportions of tip, bridge, and face shape.
- Men in particular often have thick skin, abundant subcutaneous fat, and lower elasticity — so the depth and direction of the incision site matter.
"I want alar surgery — what's a good way to set the design?"
Questions about the nostrils keep growing. Where people once focused on raising the bridge, interest has shifted to nostril design that considers harmony with the whole face. Men concerned about a bulbous nose especially often need the nostrils examined together. This article organizes what to check to reduce failure in alar surgery — the differences in incision methods and the elements read in design.
01
With a bulbous nose and wide nostrils, what is the problem?
People concerned about a bulbous nose often have not just a blunt tip but nostrils that are wide and spread together.
Men in particular often have thick skin, developed sebaceous glands, and cartilage structure around the tip spread wide. In such cases, bridge augmentation or tip correction alone makes the desired improvement hard to find.
A wide bulbous nose can make the center of the face look stuffy and heavy, or lead to a proportion problem where the nose looks short and blunt from the side. In such cases, the dimensionality and harmony of tip, nostrils, and bridge line must be read together for a natural impression to be expected. What is checked at the tip can be seen in more detail in the nasal tip surgery guide.
02
Does reducing only the nostrils solve it?
One might simply think "if the nostrils are wide, just reduce them" — but in reality it is not so.
A natural, smooth result can be expected only when the nostrils are formed together with the overall proportions of tip, bridge, and face shape. Conversely, adjusting only the tip can make the nostrils look even wider and blunter. That is why diagnosing and designing the whole nasal structure together, rather than looking at the nostrils alone, matters.
There is one more easily missed point: if the nostrils become too narrow, the nostril openings can look protruding instead. That is why reducing as much as possible cannot be the goal.
03
What incision methods exist for alar reduction?
Alar reduction broadly divides into two.
| Incision method | Approach | Characteristics |
|---|---|---|
| External incision | Incises along the outer alar-lobule line to narrow the overall width | Can make the spread lobule itself smaller; gives an impression of the facial center looking tidied from the front |
| Internal incision | Incises inside the nostril entrance to gather the nostrils inward | No scar shows externally; a naturally narrowing shape |
Male alar lobules in particular often have thick skin, abundant subcutaneous fat, and low elasticity — so the depth and direction of the incision site is very important. Done carelessly, the nostril shape can become asymmetric or deform unnaturally — a part requiring substantial experience and skill.
04
What is checked in a design consultation?
It is not just deciding how many millimeters to reduce the nostrils. A pre-surgery design consultation reviews the following together.
- Facial proportion analysis — how the proportions of the whole face are
- Skin-thickness assessment — how the skin and subcutaneous fat state affects the incision plan
- Cartilage-structure diagnosis — how widely the cartilage around the tip is spread
- The flow of the side view — whether the line from the side is natural
- The gap with the desired impression — whether there is a gap between the impression you want and your actual facial image
Because each person's facial line and desired impression differ, the approach is not a standardized one. Some want a soft, natural impression; others prefer a defined, masculine line. A nose line that suits the person can be found when face shape, the intensity of the features, and the structural characteristics around the nose are all considered.
05
Summary — overall diagnosis comes before incision position
The key to reducing failure in alar surgery lies less in the choice of incision method itself than in diagnosing the proportions of nostrils, tip, bridge, and face shape together. Since nostrils that become too narrow can themselves be a problem, judging by how harmonious the result is with your face — not how many millimeters are reduced — matters.
If you wonder about a design that suits your nasal structure, it can be confirmed in a 1:1 video consultation. Actual correction cases can be seen in the before-and-after photos.
