Alar base reduction changes the width of the nostril base and the outward flare of the nostril rims. It does not narrow the tip, the cartilage sidewalls or the bony part of the nose, and it does not lift or refine the nasal tip. In before-and-after photographs the difference is typically measured in a few millimetres per side, and yet it can visibly alter the frontal impression of the nose — because the eye reads the relationship between the nostril base and the rest of the face rather than absolute measurements. The change is real, small, and permanent, and it is delivered through incisions on visible external skin.
The honest summary of before-and-after expectations: a narrower, less flared nostril base that sits in better proportion to the face, achieved with a scar at the nostril margin, without perfect symmetry, and only fully judgeable months after surgery. Anyone hoping for a photograph-level transformation of the whole nose is looking at the wrong procedure.
Three different widths, three different excisions
Most disappointing results in this area come from operating on the wrong component. What patients call a wide nostril is usually one of the following, and they require different incisions in different places.
- Alar base width. The distance between the points where the nostrils attach to the cheek. Reducing it moves the whole attachment inwards, which changes the frontal width of the lower nose.
- Alar flare. The outward convexity of the nostril rim above its attachment. A nose can have a normal base width with markedly flaring rims, and reducing the base in that case leaves the flare untouched while narrowing the nostril opening — the classic mismatch.
- Nostril sill excess. Excess tissue in the floor of the nostril. Correcting it requires an excision within the sill rather than at the outer crease, and doing it inadvertently while addressing flare narrows the airway more than intended.
These frequently coexist in varying proportions, which is why planning is done as a combination rather than as a single manoeuvre. It is also why the photographic result varies so widely between patients described as having had “the same” procedure.
Apparent width can come from inadequate tip support
A nostril base can be numerically wide, or it can be wide only relative to a tip that has collapsed inwards. Where the tip lacks projection, the nose flattens against the face and the alar rims are pushed outward — the width is a downstream consequence of inadequate support in front, not excess tissue at the sides. Reduce the base in that anatomy and the nose becomes narrower and flatter, which is rarely what the patient wanted; increase tip projection instead and the same alar tissue is drawn inward with no external incision at all.
When the anatomy permits, adding support to an under-projected tip can be more conservative than removing tissue from the nostril base. Tissue removed at the alar base is difficult to replace, whereas correcting projection may reduce apparent width without an external alar scar. The practical question to carry into a consultation is whether the width is genuinely at the nostril base or partly the result of inadequate tip projection.
The second point follows from it. Alar base reduction is a subtractive, essentially irreversible operation on facial skin performed for a change of a few millimetres. That ratio of permanence to magnitude argues for planning at the conservative end of the range. A slightly under-corrected base can be revised. An over-resected one produces a pinched, notched or unnaturally small nostril, and correcting that requires grafting with an outcome that is far less predictable than the original problem.
Where the scars sit, and how they behave
Alar base work is external by necessity. Incisions are placed in or immediately adjacent to the natural crease where the nostril meets the cheek and, where sill excess is addressed, within the nostril floor. Well-placed, they usually settle into that crease and become difficult to notice at normal conversational distance.
They do not disappear. Close inspection, harsh overhead lighting and high-resolution photographs will often reveal them, and healing varies with skin type — thicker, more sebaceous or more pigmented skin can produce a firmer or discoloured line, and some individuals scar less favourably regardless of technique. A scar that crosses out of the crease onto the cheek skin, usually because the excision extended too far laterally, is considerably more visible and is one of the reasons excision planning matters more than excision size.
Two other technical points affect the photograph rather than the anatomy. Excision that removes the natural curve of the crease can flatten the transition between nostril and cheek, producing a change that reads as “operated” even when width is improved. And excision that alters the shape of the nostril opening rather than its position can leave a nostril that is narrower but a different shape from its partner — which the eye detects more readily than a millimetre of width.
Symmetry: what is achievable and what is not
Nostrils are almost never identical before surgery. Differences in rim height, flare, base position, sill width and the underlying cartilage are the norm, and the septum is frequently deviated, which tilts the whole base. Surgery is therefore not a matter of removing the same amount from each side; it usually means removing different amounts and sometimes performing different excisions on each side.
Even then, healing is not symmetrical. Scars contract at different rates and swelling resolves unevenly, so the two sides commonly diverge for a period before converging. A well-planned result is one where asymmetry is no longer noticeable in ordinary interaction — not one where the nostrils measure the same. Any promise of exact symmetry should be treated cautiously because the starting anatomy is rarely symmetrical and healing does not proceed identically on both sides.
Reading before-and-after photographs properly
| What to check | Why it matters |
|---|---|
| Camera angle and distance | Wide-angle phone lenses and low angles exaggerate nostril width; a change in angle alone can imitate a surgical result |
| Lighting | Flat frontal lighting hides both scars and contour changes; the same nose looks different under overhead light |
| Interval since surgery | Images taken within weeks show swelling and immature scars, not the settled result |
| Whether other work was done | Most alar base reductions accompany rhinoplasty; the visible change may be largely from tip or dorsal work |
| Base-view images | The frontal view flatters; the view from below shows nostril shape, sill and symmetry honestly |
| Whether scars are visible at all | If no image shows the crease closely, the most relevant trade-off is being concealed |
Online galleries and forum threads are a poor basis for a plan for a further reason: you are comparing your face with a different set of proportions, skin type and cartilage. Nostril width that suits a broad face with strong cheekbone projection will look different on a narrow one, and the target has to be your own facial frame rather than an admired photograph.
Early appearance versus the settled result
Immediately after surgery the base looks tight and often over-narrowed, with swelling, small crusts along the incisions and firm, slightly raised scar lines. Over the following weeks swelling settles and the nostrils relax outwards a little — which is expected and is part of why the plan is not made to look correct on day one. Scars pass through a phase of firmness and pink or red discolouration before gradually softening and fading, and this maturation continues for many months. Timelines vary between individuals, and precise universal dates overstate what can be known.
The practical consequence is that the appearance at two weeks predicts very little, and judging the outcome then causes avoidable distress and occasionally prompts revision requests that would not have been made a year later. Where the procedure accompanies rhinoplasty, the surrounding nose is also swollen, and the nostril base is being read against a shape that has not yet declared itself.
Expected findings include soreness, tightness, swelling and a firm scar line. Contact the treating team about increasing rather than settling pain, spreading redness, discharge, wound separation, a suture problem, or a scar becoming progressively raised, thickened or itchy — early scar management is more effective than late. Seek urgent assessment for fever with spreading facial redness, or rapidly increasing swelling and pain.
What cannot be judged without examination
Millimetre planning is done with the patient in front of you. Base width relative to the intercanthal distance, the true contribution of flare versus base versus sill, tip projection and support, skin thickness and scarring tendency, septal position, and how the nostrils behave on smiling all change the plan. Breathing matters as much as appearance: some noses that look wide are already breathing marginally, and narrowing the nostril aperture in that setting is not neutral.
Motivation belongs in the assessment too. A long-standing, specifically described concern about nostril width tends to be well served. A recent, intensely distressing preoccupation, or a target borrowed from a photograph of someone else, is a reason to slow down rather than to operate — and for a small change of this kind, waiting costs nothing.
Deciding sensibly
- Establish which component is wide: base position, rim flare or sill. Ask which excisions are planned and where.
- Ask whether tip projection or support would reduce apparent width without external excision.
- Ask to see base-view photographs at twelve months, with the crease visible, rather than frontal images alone.
- Agree that the plan errs conservatively, and that a small revision is preferable to over-resection.
- Confirm your breathing has been assessed, not assumed.
- Accept a scar, imperfect symmetry, and a result that is judged months rather than weeks after surgery.
Further detail on how the excisions are planned and performed is set out on the alar base reduction page. The useful next step is an examination that names the structure responsible for the width you dislike — because a few millimetres of permanently removed skin should follow a diagnosis, not a photograph.
