Columellar Strut

The columellar strut is used in rhinoplasty to support the nasal tip.  It serves as a floating graft.  In effect the lower lateral cartilage of the nasal tip are supported by this graft which in turn allows for improved projection and support.

A columellar strut can be placed endonasally or externally.  When placed endonasally, the graft fits into a tight pocket between the medial crura, helping to straighten and support the nasal tip.  When placed externally, the graft is secured in place with a suture.

Generally speaking, a columellar strut is more difficult to predict nasal tip position based on the fact that the nasal tip is not secured in place.  It has the advantage of requiring less cartilage than a caudal extension graft. 

A columellar strut can be made with septal cartilage, auricular cartilage, or costal cartilage.

A columellar strut is often distinguished between an extended columellar strut or "power strut".
