Alar base reduction: narrowing wide nostrils and a broad nasal base

Alar base reduction narrows wide nostrils and a broad nasal base by removing small wedges of tissue where the nostrils meet the cheeks, and it is the specific tool for a nose that looks too wide from the front rather than too bumpy in profile.

It helps a particular concern, so the first step is identifying whether width is really the issue. Many people focused on making a big nose look smaller are actually bothered by the width of the base and the flare of the nostrils, not by the bridge or a hump. Alar base reduction targets exactly that: it brings the outer edges of the nostrils inward so the base sits in better proportion with the eyes and mouth. It does nothing for a bump on the bridge, which is a separate operation covered in reducing a dorsal hump.

The technique is precise and conservative. A surgeon removes carefully measured wedges of tissue at the base of the nostrils, often called a Weir excision, and closes them so the scar hides in the natural crease where the nostril meets the cheek. It can be done on its own under local anesthesia or, more often, as one refining step within a full rhinoplasty that also addresses the bridge and tip.

The tradeoffs are real and worth understanding. Because the incisions sit at the base of the nose, there is a fine scar that usually fades well but is permanent, and over-narrowing looks just as unnatural as leaving the base too wide, which is why restraint matters and why the change is planned in millimeters. A base narrowed too far can pinch the nostrils and even affect airflow.

The practical framing is that alar base reduction is a focused, powerful step for a specifically wide nose, best judged as part of the whole-face balance rather than in isolation. If your goal is simply to make a large nose look smaller, our full rundown of every option places nostril narrowing in context against contouring, filler, and the rest of a rhinoplasty.
