When patients describe what bothers them about their profile, they often point to the bridge or the tip. But a surprising number are bothered by something lower down that is harder to name: "I can see too much of my nostrils," or "the bottom of my nose hangs down." Both concerns relate to the columella, the column of tissue between the nostrils, and how it sits relative to the nostril rims. This is a vertical, side-profile issue. It is separate from nostril width or flare seen from the front, which is addressed with alar base reduction.nt from a tip that sits low all the time. A tip that has gradually dropped over years is usually related to aging or weakened support, a separate issue I have written about elsewhere. A dynamic tip looks normal at rest and only drops with expression.
What is "columellar show"?
In a side profile, the nostril rims (the alae) and the columella form a gentle curve that frames the nostril. A small amount of the columella is normally visible below the nostril rim. Surgeons call this columellar show. The ideal is generally considered to be about 2 to 4 millimetres. Less than that, and the nose can look like it has a "hidden" or retracted columella. More than that, and the nostrils look exposed from the side.
The important point is that the same visible problem can come from opposite directions. Too much nostril show can mean the columella hangs too low, or the nostril rim has pulled too high, or both. Each requires a different correction, which is why a careful diagnosis matters more here than almost anywhere else in the nose.
The four common patterns
Hanging columella. The columella sits too low, often because the lower edge of the septum or the inner portions of the tip cartilages are prominent. The nostril rims are normal.
Alar retraction. The nostril rim is arched too high, exposing the inside of the nostril. This can be natural, but it is also a common result of over-aggressive tip cartilage removal in a previous rhinoplasty.
.Retracted columella. The columella sits too high or too far back, so the base of the nose looks short or "hidden" in profile. This is often seen after excess septal cartilage removal or loss of support.
Hanging ala. The nostril rim droops low and hides the columella, giving the nose a heavy look at its base.
Some patients have a combination, such as a hanging columella on one side and a retracted rim on the other, which is one reason nostrils can look uneven in profile.
How each one is corrected
Because these are opposite problems, the solutions are often opposite as well.
A hanging columella is usually corrected by carefully trimming or repositioning the lower edge of the septum or the inner tip cartilages, raising the columella to its ideal position.
Alar retraction is usually corrected by adding support rather than removing tissue. Thin cartilage grafts along the nostril rim, or small composite grafts of skin and cartilage, can bring the rim down. Simply trimming the columella to "match" a retracted rim makes the nose look shorter and does not address the real problem.
A retracted columella is usually corrected by adding cartilage at the base of the columella or rebuilding support with a columellar strut or septal extension graft.
A hanging ala can sometimes be corrected by removing a small amount of tissue from inside the rim.
Why this matters for breathing
The nostril rims are part of the external nasal valve, the entrance to the airway. Weak or retracted rims can collapse inward during deep breathing. When I correct alar retraction with rim grafts, the same grafts often strengthen the nostril and help it stay open. The valve article in our Learning Center covers this airway connection.
Small millimetres, big difference
Changes of one or two millimetres at the columella and nostril rim can transform the balance of the profile. It is also an area where over-correction is very visible. My approach is to make conservative, measured changes and to evaluate the nose from the side, the front, and below before deciding on each adjustment.
Key takeaway
Too much nostril show is not a single problem. It can come from a hanging columella, a retracted nostril rim, or both, and the correction depends entirely on which is responsible. A careful assessment of the alar-columellar relationship is one of the quiet details that separates a natural rhinoplasty result from one that looks operated.
Frequently Asked Questions
How much nostril should show from the side?
A small amount of the columella, generally about 2 to 4 millimetres, is considered ideal in profile. The right amount varies slightly with each face.
Can alar retraction be fixed without surgery?
Filler is sometimes used to soften very mild rim irregularities, but true alar retraction generally needs structural support from cartilage grafts.
Is a hanging columella a common reason for revision?
Yes. Both hanging columellas and retracted nostril rims are common concerns after a previous rhinoplasty, particularly when tip cartilage was removed without being reinforced.
