Rhinoplasty encompasses a broad range of techniques to reshape the nose. For patients with too much height, width or volume to the nose, often rhinoplasty may be performed by removing excess cartilage and bone from the nose to create a smaller, more refined shape. In the case of revision rhinoplasty, when a previous nose job has depleted cartilage and bone from the nose, additional cartilage may be necessary to re-establish support or to provide structure to create a more aesthetically pleasing shape.
Some patients naturally have anatomic characteristics that predispose them to needing cartilage beyond what is available in the nose to create the desired shape changes, commonly in Asian and black patients, and sometimes with Hispanic patients and white patients. The shape of the nasal tip derives from the size, shape and resiliency of the tip cartilage (lower lateral cartilages) and the overlying skin envelope, including the subcutaneous fat and so-called “nasal SMAS” or fibrofatty tissue investing the lower lateral cartilages. In effecting change to the shape of the nasal tip, the rhinoplasty surgeon must respect the intrinsic tip support mechanisms and perform maneuvers to maintain or even bolster that support. When cartilage is excessively removed from the tip of the nose in an attempt to reduce bulbosity or to create definition, width and volume may be reduced but at the expense of undermining nasal tip support. Sometimes this weakening manifests immediately, however more commonly it takes years to reveal itself in the form of external nasal valve collapse, nasal tip ptosis, and the dreaded “pinched” appearance.
In patients with a dearth of strong native cartilage, and in patients who’s tip cartilage will excessively weaken with narrowing of the cartilage, extra support will allow the rhinoplasty surgeon to reshape the nasal skin envelope while obviating the potential for future pinching and collapse of the tip and nasal valves. An excellent source of this additional cartilage can be costal cartilage as it is 100% incorporated into the nose in a permanent fashion while still providing a degree of flexibility. In the past rib cartilage use in rhinoplasty achieved a somewhat skewed representation to the general public in that it was reserved for primarily reconstructive rhinoplasty and cases in which a collapsed note was rebuilt to be strong and sturdy – which runs counter to the delicate and refined aesthetic most cosmetic patients seek.
This misconception stems from the fact that many rhinoplasty surgeons in the past over-built noses during reconstruction to prevent future collapse and to ensure durable support. Contemporary rib cartilage rhinoplasty has evolved significantly in the past decade, and today rib cartilage represents simply a building material each individual rhinoplasty surgeon can use to express his or her artistry on each individual patient. Just like flour is a building material for pastries or cakes, and not every flour-based edible as the same shape, rib cartilage is simply a building material. Surgeons have refined techniques to the point that small, delicate pieces of rib cartilage can be used to reshape the nose into small, delicate shapes. The key then is discerning more about the specific surgeon’s artistry, experience and skill-level rather than fixating simply on the choice of building material.
