The basic indication is when the width of the nasal base is disproportionately wide relative to overall facial balance. However, in those with a wider face, reducing the alar size can sometimes make the lateral profile appear even wider; the decision should be based not on fixed measurement values but on harmony with the overall face.[1]If there is nasal obstruction or elevation of the alar margin, there are points to confirm first[2][3].
What type of nose is alar reduction suited for?
When the width of the nasal base is disproportionately wide relative to facial proportions. Alar reduction is a technique that narrows the width of the nasal base at the boundary between the alar wing and the cheek, and the principle is to combine it with techniques on the nasal tip to achieve overall balance[4]Deformity of the nasal base itself has also been compiled as a review in specialist journals[5].
External nasal evaluation is performed from three directions—frontal, lateral, and basal—examining items such as overall facial balance, skin quality, asymmetry, nasal deviation, alar margin, alar base, and alar projection[6]The decision is not made by measuring the alar region alone in isolation.
Is it true that if you have a wide face, it can look even wider?
That is the observation reported. In those with a wider face, alar reduction can sometimes make the lateral profile appear even wider[1].
Therefore the criterion for judgment is not the numerical width of the alar region itself, but harmony with the overall face[1]An explanation that confirms together how the nose appears within the face aligns better with this observation than an explanation that starts with 'reducing by X millimeters.'
If the nares are short, is it enough just to reduce the alar size?
There can be deficiencies. In the combination of short nares and a wide alar base, performing both alar reduction and lengthening of the nares together yields aesthetically favorable results, as has been established[7].
Even with the same concern of 'large alar region,' whether it is a width issue or a balance issue with naris length changes what surgery is needed. This is difficult to distinguish by looking in a mirror alone.
When should one be cautious?
When the alar margin is already elevated. Excessive removal around the alar region can cause alar margin retraction, as shown by reports of grafting techniques for its prevention and correction[2].
Psychological preparation for surgery is also listed as an element to evaluate alongside appearance harmonious with the face and nasal airway function[8]There is a report that among those who consult for desired nasal shape, the proportion with symptoms equivalent to body dysmorphic disorder is high[9]When you sense that concern is strong, that becomes a matter to discuss comprehensively.
For someone with nasal obstruction, what should be examined first?
The state of the nasal airway. Post-rhinoplasty nasal obstruction includes collapse or narrowing of the internal and external nasal valves and scarring of the internal nasal valve[3]The surgery that narrows the nasal base relates to the width of this region.
Methods to objectively measure airflow have also been studied; there is research evaluating the opening of the nasal valve using maximum nasal inspiratory flow and a flowmeter[10]If there is nasal obstruction that concerns you, mentioning it before consulting about appearance is the more natural sequence.
Four things to confirm during consultation
First is whether the concern is the width of the alar region or the balance with naris length[7]Second is how it will appear when the alar region is narrowed within the overall face[1]Third is the position of the alar margin and nasal airway patency[2][3]Fourth is where the incision will be placed and what will be done together[4].
Regarding incision methods, there is research comparing functional and aesthetic outcomes between open and closed techniques[11]Facial skeleton and skin quality vary from person to person, so how much your nose can be changed should be determined after an actual examination.
