Saddle Nose and the Low Bridge: How Dorsal Augmentation Rebuilds the Nose
Most people picture rhinoplasty as a reduction: taking down a hump, narrowing a tip, making the nose smaller. However, some patients need their nose built up, not taken down, and the techniques involved are quite different.
These patients generally fall into two groups. The first have a naturally low bridge, often a family trait, and would like a little more height and definition between the eyes. The second have what is called a saddle nose: a bridge that has collapsed or sunk in the middle, creating a scooped profile, usually because the internal support of the nose has been lost.
What causes a saddle nose
The middle of the nasal bridge is held up largely by the septum. When that support is damaged or removed, the bridge can sag. The most common causes are:
Trauma, including a broken nose or an untreated septal hematoma that damaged the septal cartilage.
Previous nasal surgery in which too much septal cartilage was removed or the remaining support was weakened.
Cocaine use, which can destroy septal cartilage and lining.
Rarely, inflammatory and autoimmune conditions that affect cartilage, such as granulomatosis with polyangiitis or relapsing polychondritis.
When there is no clear explanation for a collapsing bridge, I ask detailed questions and may recommend medical testing before planning surgery. If an inflammatory condition is involved, it needs to be controlled first. Rebuilding a nose while the underlying disease is still active puts the new structure at risk.
Why it matters beyond appearance
A saddle nose may not only be a cosmetic issue. Loss of septal support often affects the middle portion of the nasal airway and can contribute to breathing problems. It can also undermine the tip, which may lose projection or appear to sink back toward the face. For that reason, saddle nose repair may require a structural operation: restoring the septum and tip support, not just filling in the dip.
How the bridge is rebuilt
Dorsal augmentation means adding material along the bridge to restore height and a smooth line. There are several options, and the right one depends on how much height is needed, how much of your own cartilage is available, and the quality of your skin.
Rib cartilage. This can be either your own rib or donor rib. I currently prefer donor rib because it avoids a second surgical site, is just as effective, and carries no increase in risk.
Diced cartilage wrapped in fascia. Cartilage is cut into very small pieces and placed inside a thin sleeve of the body's own connective tissue, then shaped along the bridge. This technique can be molded precisely and avoids the warping that can occur with a single solid piece of carved rib cartilage.
Synthetic implants. Silicone and similar implants are widely used in some parts of the world. They can look good initially, but they carry a higher long-term risk of infection, shifting, and extrusion through the skin, particularly in thin skin or in noses that have already had surgery. For most of my patients, I prefer to use their own tissue.
Height is a design decision
One of the most common mistakes in augmentation is building the bridge too high. A bridge that runs in a perfectly straight, tall line from the forehead to the tip looks artificial and can unbalance the face. The goal is a bridge that suits your features, your heritage, and your tip, and that looks as though it has always been there. This is where pre-operative imaging is helpful: it lets us discuss how much height looks right before any decisions are made in the operating room.
What recovery is like
Recovery from augmentation rhinoplasty is similar to other rhinoplasty, with a few differences. If rib cartilage is used, often it is donor rib that has been harvested from another person. Swelling along the new bridge settles gradually, and the final contour takes months to refine, especially in thicker skin.
Key takeaway
A low or collapsed bridge can be rebuilt, and in most cases, the most durable results come from using donor rib cartilage. If you have a saddle nose, understanding why it happened is just as important as deciding how to fix it.
