Before deciding on a specific technique, a surgeon must first determine what exactly needs to be corrected and how to achieve it while preserving natural appearance and airway function. Alarplasty In Riyadh The alar base sits near the centre of the face, meaning even a small change can significantly alter facial impression—which is why restraint matters .

Assessing the Three-Dimensional Problem

Surgeons evaluate the nostrils in several conditions: at rest, from a three-quarter view, and while smiling or breathing normally. The key diagnostic question is whether the issue is a structural feature or a dynamic response—some patients have a consistently broad base, while others experience excessive flare when smiling .

A critical reference point is whether the alar base width exceeds the intercanthal distance (the width between the inner corners of the eyes), which is the clinical benchmark for balanced nasal proportion .

Common Diagnostic Pitfalls

One of the most frequent errors is treating a nostril base that appears wide simply because the tip lacks support, projection, or rotational balance. In these cases, the base is not necessarily "too wide"—it is visually dominant because the rest of the nose is not carrying its share of structure. If structural changes to the tip are needed, they can alter how the base reads, sometimes reducing perceived width without requiring base excision .

Primary Procedure Variations

Weir Excision

The most common technique for reducing nostril width and flare. A small wedge of tissue is removed from the junction where the nostril meets the cheek (the alar-facial groove), with the incision hidden in this natural crease. A typical reduction removes 2 to 4 millimetres of tissue .

Sill Excision

Targets the size of the nostril opening itself. An incision is made at the nostril sill (the bridge of tissue at the base of the nostril) to decrease the length and width of the nostril. Often combined with a Weir excision for comprehensive refinement .

Sail Excision

A technique designed for patients with a hanging or globular ala—a convex, rounded alar lobule that is common in Southeast Asian noses. A precisely marked piece of inner nasal vestibular skin, shaped like a sail, is removed to lift the alar rim. Because the incision is internal, this technique leaves no external scar and changes the alar morphology from a globular shape to a more aesthetically pleasing ridge-shaped lobule .

Internal Alaplasty (Alar Cinching)

For patients of colour at higher risk of scarring, an internal approach with laterally based rotation advancement flaps and a diamond wedge nasal floor excision can narrow the ala while concealing incisions intranasally, avoiding the visible scar and keloid risk of traditional Weir excisions .

The Golden Rule: Conservative Execution

Alarplasty is irreversible—once tissue is removed, it cannot be restored. Aggressive excisions may cause an unnatural, "pinched" appearance and potential nasal obstruction. A responsible surgical plan uses conservative tissue removal and realistic scar management .

Frequently Asked Questions

What is the difference between Weir and Sill excisions?

Weir excision reduces nostril width by removing tissue from the alar-facial groove; Sill excision reduces the nostril opening itself via incisions inside the nostril. They are often combined.

What is the sail excision technique?

A technique for correcting a globular or hanging ala by removing a precisely marked piece of inner nasal vestibular skin, shaped like a sail, to lift the alar rim without an external scar .

When might a surgeon avoid external incisions?

Surgeons may avoid external incisions in patients of colour who are at higher risk of visible scarring, keloids, or post-inflammatory hyperpigmentation .

Is alarplasty reversible?

No, the reduction in nostril width is permanent because it involves removing tissue. This is why a conservative approach is critical .

Can alar base reduction affect breathing?

If done aggressively, narrowing the nostril base can compromise airflow during deep breathing and exercise .
