Does columellar lowering last long-term? What long-term outcomes reveal

Position changes in the nose from columellar lowering surgery are repeatedly documented in textbooks and research reports[1]However, there is limited long-term data directly comparing how many years each method lasts, and there is still no clear answer about which is better[2]

What effects have been confirmed?

What has been confirmed is the effect that the shape of the nose actually changes. With columellar strut grafting between the medial crura (the left and right cartilage inside the columella), it is documented that the tip height increases, the columella lengthens, the apex of the nostril rises, the angle below the nose opens, and the base of the columella advances forward[1]In grafting procedures that fix to the caudal septum (the lower portion of the nasal partition), the tip can simultaneously be rotated downward and the columella advanced forward. Because it is fixed, strong support is obtained.[1]Up to the point that the nose position moves, there is generally agreement among the referenced materials.

How well does it last over the long term?

To be honest, we can say it is "easy to maintain" only when conditions are favorable. When a straight and sturdy medial crura is combined with a rigid columellar strut graft or septal extension graft (which lengthens the nasal partition), the nasal tip position is likely to be maintained longer, as documented. However, in exchange, there is the downside that the nasal tip becomes firmer.[1]Regarding setting the nasal tip height at the target position and suppressing post-operative descent, caudal septal extension grafting connecting end-to-end is considered more reliable than columellar strut grafting.[3]However, long-term outcome data directly comparing the two are limited, and it has not been determined which is superior in the long term.[2]

What changes in the noses of Asian people?

Asian noses are characterized by weak septal cartilage (the cartilage that divides the nose) and thick skin. For this reason, it has been argued that support grafts and Dorsal Septal Extension Grafts alone may not efficiently maintain tip projection for long periods.[4]Caudal Dorsal Septal Extension Grafts tend to be used in a longer, wider, and more rectangular shape to compensate for this weakness.[5]In a retrospective analysis of 24 cases that combined spreader grafts with Dorsal Septal Extension Grafts, improvements in both aesthetic and functional outcomes have been reported.[6]

How often are displacement or asymmetry reported?

Displacement can occur. After Dorsal Septal Extension Grafting, if the supporting L-shaped cartilage is weak, the graft may tilt, potentially leading to asymmetry of the tip, columella, and nostrils.[1]If a previous surgery resulted in overrotation of the tip due to support placement or suture reduction, a separate corrective procedure to reorient the tip may be necessary.[1]Additionally, quantitative data on graft resorption (the gradual reduction of transplanted cartilage in the body) was not found in the materials reviewed for this discussion.

How do I make decisions when some information is unknown?

The key is to separate what is known from what is unknown. Two things are clear: that cartilage grafting can reposition the tip, and that long-term stability depends not only on graft type but also on the strength of the medial crura and skin thickness.[1][4]What remains unknown is the comparative durability of the two surgical techniques—how long each actually lasts.[2]During consultation, have your physician examine how much cartilage remains in your septum, how strong your medial crura are, and how thick your skin is. Then ask specifically about the realistic range of outcomes you can expect, which will help you make a more confident decision.[1]
