is patient presented for secondary rhinoplasty. He was unhappy with his overreduced dorsum and unrened, asymmetrical tip. e frontal view shows ill-dened dorsal aesthetic lines and severe tip asymmetry. On lateral view, the dorsum is overreduced and concave.
e operative goals included the following:
Rene the tip.
Create a straight dorsum with dorsal augmentation and smooth dorsal aesthetic lines.
Reposition the radix more superiorly.
Surgical Plan
1. Use an open approach with a stair-step transcolumellar incision and bilateral
infracartilaginous extensions.
2. Harvest septal cartilage.

CONCLUSION
Autologous septal cartilage dorsal onlay gras are appropriate in primary and secondary rhinoplasty patients in whom a minimal to moderate amount of dorsal augmentation is desired. In general, better results are obtained if the total length of the dorsum from radix to septal angle is augmented rather than only a por­tion of it. However, if partial augmentation is all that is needed, it is important to bevel the ends of the gra and taper them to a thin edge so they will not create a step-o where they terminate on the dorsum.
It is preferable to augment the entire length of the dorsum from radix to septal angle rather than only a portion of the dorsum.
e disadvantages of using shaped autologous onlay gras of septal cartilage for augmentation of the nasal dorsum are the limited amount of cartilage that can be obtained from the septum and the occasional diculty in shaping the gra when dealing with a severely deviated septum because of the angulation of the septal cartilage.
KEY POINTS
Autologous septal cartilage dorsal onlay gras are appropriate in primary and secondary rhinoplasty patients in whom a minimal to moderate amount of dorsal augmentation is desired.
Dorsal augmentation is based on the relationship of the dorsum to the tip pro­jection and nasofrontal angle.
Dorsal onlay graing is indicated in patients with a low nasofrontal angle, di­minished dorsal height or an excessive concavity of the dorsal prole on lat­eral view.
e edges of the gra should be beveled at approximately a -degree angle to avoid the appearance of a step-off postoperatively.
e inverted V-frame and U-frame gras t better over the arched contour of the dorsum and are more stable than a at piece of septal cartilage.
It is preferable to augment the entire length of the dorsum from radix to septal angle rather than only a portion of the dorsum.
e only disadvantages of these techniques are the amount of septal cartilage available may be insucient or the available cartilage may be extremely devi­ated, making shaping of the onlay gra dicult.

Dorsal Augmentation: Temporal
Fascia– Wrapped Diced Cartilage
Rollin K. Daniel
T
he use of diced cartilage gras wrapped in fascia (DC-F) has numerous ad­vantages and very few disadvantages. tilage with no risk of rejection. Any combination of excised, septal, conchal, or rib cartilage can be used. In contrast to solid gras, it is not necessary to harvest a perfect and rarely found  by mm piece of septal cartilage or fuse two pieces of curvy conchal cartilage. Warping is not a risk, and foreign material (K-wire) is not needed. e gra is easily and quickly prepared by the circulating nurse or a junior assistant who dices the cartilage and loads the syringe. It is easily custom­ized for thickness ( to mm), shape (tapered or uniform), and length. e abil­ity to construct a gra with a specic shape for a specic defect is extraordinary. Molding of the gra is possible both intraoperatively and early postoperatively. e gra can be easily revised using a percutaneous No.  needle to remove a sharp edge, or a No.  blade to shave o prominences. Infection has not been a problem. Absorption has not occurred in more than  cases with a maximum follow-up exceeding years. Over a period of months, the diced cartilage solidi­es. e interspace between the diced cartilage bits is lled with brous tissue within the fascial sleeve. When removed, the gra is quite solid and semirigid. Pieces excised for shaping purposes are suciently solid for use as tip gras. His­tologic studies conrm that the individual pieces of cartilage have survived and suggest that the fascia has become a neoperichondrium.

BACKGROUND
A discussion of the role of diced cartilage gras in rhinoplasty surgery requires a review of several important points. First, the fundamental technique is not new. e use of diced cartilage alone, without a fascial sleeve, was extremely popular in Europe between the World Wars, with numerous surgeons developing carti­lage dicers and chondrojet injectors.
Second, many surgeons have used the technique for over years and are pleased with its long-term viability.
,
One of the most impressive uses of diced cartilage is cranioplasty, which demonstrates that the individual pieces coalesce into a semirigid gra with time. ird, the term diced cartilage gra can encompass a wide variation as to type of cartilage, method of preparation, and containment, which leads to confusion when comparing clinical indications, techniques, and results. A discussion of each of these points is essential.
,
It is critical to create a symmetrical dorsal platform on which to place the DC-F gra. e gra acts as a capstone to a pyramid; if the pyramid is crooked, the DC-F gra will appear to be displaced.
Cartilage
I use only autologous cartilage, which can be derived from excised material, sep­tum, or distant gras (conchal or rib). Isee virtually no justication for routine use of cadaver cartilage gras with their known long-term absorption. Under exceptional situations of age, ethnicity, or systemic risks, cadaver cartilage war­rants consideration. ese account for less than % of cases.
e length, width, thickness, and shape of the construct must be carefully de­signed.
Preparation
e cartilage should be diced—never morselized, bruised, or crushed. e goal is complete gra survival, similar to a columellar strut or spreader gra. e car­tilage is cut into .mm or smaller cubes using two  blades and then inserted into a small tuberculin syringe for easy placement. e cartilage should be diced so ne that it can be ejected from the syringe (positive spurt test).
