Alar Reduction Surgery in Singapore
Doctor-led nasal-base surgery for selected concerns involving alar flare, nostril width or nasal-sill anatomy.
The aim is proportional nasal-base refinement while preserving nostril shape, symmetry and airway function — not applying one ethnic or aesthetic ideal to every nose.
Two facts shape this whole page. Tissue removed here cannot be put back, and the incisions sit on the visible outer surface of the nose rather than hidden inside it. Both argue for conservative planning and for being certain that base width is genuinely the problem.

Alar reduction at a glance
| What it changes | The nasal base — alar flare, nostril sill width, or both |
|---|---|
| What it does not change | Bridge height, tip refinement, a dorsal hump, a deviated nose or internal airway problems |
| How it works | Carefully planned wedges of skin and soft tissue are removed and closed to narrow the base |
| Incision sites | Along the alar-facial groove, within the nostril sill, or both depending on the pattern of width |
| Anaesthesia | Local anaesthetic alone, or as part of a larger rhinoplasty under general anaesthesia |
| Scars | External and permanent, though usually inconspicuous once mature. They cannot be promised to vanish |
| Reversibility | None. Removed tissue cannot be restored, which is why under-correction is the safer error |
| Key risk | Over-resection causing notching, nostril distortion, alar retraction or airway narrowing |
| Often combined with | Tip work, since low tip projection makes a base look wider than it is |

What does alar reduction change?
Alar-base surgery can reduce selected lateral flare, sill width or nostril-base excess by removing carefully planned wedges of skin and/or soft tissue. The exact pattern depends on whether the main issue is flare, sill width or both.
Alar flare
The outer alar wall projects laterally, especially on smiling.
Nostril sill width
The floor of the nostril may contribute to a broad nasal base.
Tip projection
A poorly projected tip can make the base appear wider; reducing the alae alone may not create balanced proportions.
Nostril shape
The visible outline of each nostril, which reduction can refine but can also distort if over-done.
Asymmetry
Most noses are naturally asymmetric. Surgery can improve but rarely erases this, and it should be documented beforehand.
Dynamic flare
Flare that appears mainly on smiling behaves differently from fixed width and should be assessed both at rest and animated.
The distinction that determines the operation. Flare is the outward projection of the alar wall beyond the base; sill width is the distance across the nostril floor. Reducing the wrong one produces either a nose still visibly wide or nostrils that look pinched and unnatural. A surgeon should be able to tell you which of the two — or what proportion of each — applies to you.
Assessment is done from below as well as from the front, since the nostril outline and sill are only properly visible on a basal view. Photographs from that angle are a normal and useful part of planning, however unflattering they feel.
Incisions and scars
Incisions are commonly placed along the alar-facial groove and/or nostril sill. Scars generally mature over time but cannot be promised to become invisible.
Over-resection can create unnatural narrowing, nostril distortion, asymmetry or difficulty breathing. Conservative planning is particularly important because removed tissue cannot simply be restored.
Two technical points genuinely affect how the scar looks. Placing the incision precisely within the alar-facial crease rather than slightly onto the cheek or nostril allows the natural shadow to conceal it. And preserving a small cuff of tissue at the alar base prevents the notching — a visible step in the nostril rim — that is one of the more recognisable signs of over-aggressive base reduction.
Scar behaviour also varies with skin. Thicker, more sebaceous nasal skin can produce a more noticeable scar, and any personal or family history of hypertrophic or keloid scarring should be declared clearly, since it may change the risk calculus considerably for a purely cosmetic operation.
These scars are external and permanent. They usually mature to become inconspicuous, but unlike incisions hidden inside the nose they sit on the visible surface. Anyone unwilling to accept a small visible scar should reconsider the procedure rather than hope for invisibility.
Alar reduction versus rhinoplasty
Alar reduction changes the nasal base. It does not directly increase bridge height, refine tip cartilage, correct a dorsal hump, straighten a deviated nose or address internal airway problems.
If nasal-base width is partly driven by low tip projection or broader rhinoplasty anatomy, base reduction may need to be planned together with other nasal surgery.
This relationship is the commonest reason base reduction alone disappoints. When the tip sits low, the nose reads as flat and wide, and narrowing the base without addressing projection can leave the nose looking pinched at the bottom while still lacking definition. Conversely, improving tip projection often makes the base look narrower on its own — which is why some patients need less base reduction than they expected, or none.
The sensible sequence when both are being considered is to plan them together and perform base reduction last, once projection is established, so the amount removed is measured against the new shape rather than the old one.
Risks and recovery
Potential complications include bleeding, infection, delayed healing, visible or hypertrophic scars, nostril asymmetry, over- or under-reduction, contour notching, alar retraction, narrowing of the external nasal valve and need for revision.
Swelling around the nasal base can temporarily distort nostril shape. Final scar and contour assessment takes longer than the early postoperative period.
The airway consideration is specific and worth understanding. The external nasal valve is the opening of the nostril itself, and narrowing it too much can produce a sensation of blocked breathing, particularly on deep inspiration or exercise. Patients whose nostrils already collapse inward when breathing in firmly are at higher risk, and this is checked as part of assessment rather than assumed.
Because the procedure is irreversible, a deliberately conservative first operation is the sound approach. Removing a little more later is straightforward; replacing tissue is not, and correcting an over-narrowed base often requires grafting with a considerably less predictable result.
| Period | What is typical | What matters most |
|---|---|---|
| First week | Swelling and bruising around the nostrils. Sutures in place. Nostrils may look uneven. | Keep incisions clean, avoid stretching the area, no heavy lifting. |
| Weeks 1–2 | Sutures removed. Scars are pink and firm, which is normal at this stage. | Do not judge symmetry yet. Begin scar care as directed. |
| Weeks 3–8 | Swelling settles and nostril shape becomes more representative. | Sun protection on scars. Silicone or taping if advised. |
| Months 3–6 | Scars soften and fade gradually. Contour largely settled. | Photographic comparison from front and basal views. |
| Months 6–12 | Final scar maturation and definitive result. | Fair assessment; revision discussion belongs here if needed. |
Sun protection matters more than patients expect. Fresh scars exposed to Singapore's year-round ultraviolet can darken persistently, and post-inflammatory hyperpigmentation along the incision is a real risk in Fitzpatrick III–V skin. Diligent sun protection for several months materially improves the final appearance.
Frequently asked questions
Does alar reduction make the whole nose smaller?
It changes selected dimensions of the nasal base. Bridge, tip and overall nasal projection are separate anatomical components.
Will the scars disappear?
No scar can be guaranteed to disappear completely. Placement within the alar-facial crease and good scar care aim to make them inconspicuous as they mature, but they are external and permanent.
Can too much be removed?
Yes. Excessive reduction can distort nostril shape, cause notching or affect the external nasal valve, which is why conservative planning matters and why removing a little more later is the safer approach.
Can alar reduction be combined with rhinoplasty?
Yes, and often should be. Where both are planned, base reduction is usually performed last so the amount removed is measured against the new tip projection.
What is the difference between flare and sill width?
Flare is outward projection of the alar wall beyond the base; sill width is the distance across the nostril floor. Reducing the wrong one leaves the nose either still wide or looking pinched.
Might I need less reduction than I think?
Possibly. Improving tip projection often makes the base look narrower on its own, so some patients need less base reduction than expected, or none at all.
Could it affect my breathing?
Narrowing the nostril opening too much can cause a blocked sensation, particularly on deep breathing or exercise. Patients whose nostrils already collapse inward on firm inspiration are at higher risk and this is checked beforehand.
Is it reversible?
No. Removed tissue cannot be restored, and correcting an over-narrowed base usually requires grafting with a less predictable result.
What is notching?
A visible step or irregularity in the nostril rim, one of the recognisable signs of over-aggressive base reduction. Preserving a small cuff of tissue at the alar base helps prevent it.
Can it be done under local anaesthetic?
Yes, alar reduction alone is commonly performed under local anaesthetic. When combined with rhinoplasty it forms part of a general anaesthetic procedure.
Why do I need photographs from underneath?
The nostril outline and sill are only properly visible on a basal view, so that angle is necessary for planning however unflattering it feels.
Will my nostrils be perfectly symmetrical?
Most noses are naturally asymmetric and surgery improves rather than erases this. Pre-existing asymmetry is documented beforehand precisely because it is often noticed only afterwards.
My nose only looks wide when I smile — does that change things?
Yes. Dynamic flare on smiling behaves differently from fixed width, so assessment is done both at rest and animated before deciding what to reduce.
Does skin type affect the scar?
Thicker, more sebaceous nasal skin can produce a more noticeable scar, and any history of hypertrophic or keloid scarring should be declared as it may change the risk calculus.
How important is sun protection afterwards?
Considerably. Fresh scars exposed to Singapore's year-round ultraviolet can darken persistently, and post-inflammatory pigmentation along the incision is a real risk in darker skin types.
When can I return to work?
Many patients feel presentable within about a week once sutures are removed, though pink scars and residual swelling continue for longer.
When is the result final?
Contour is largely settled by three to six months, with scar maturation continuing to around a year. Revision discussion belongs at that point.
Can I have it if I have had previous nose surgery?
Often, but declare it. Previous surgery alters tissue and blood supply and changes both planning and risk.
Is alar reduction claimable under MediSave or insurance in Singapore?
Purely cosmetic nasal surgery is generally not claimable. Where there is a documented functional indication, check directly with your insurer.
