Both crushed and diced cartilage is used to smoothen out or camouflage nasal surface area's where cartilage is placed in the nose , like the dorsum, to conceal any irregularities. Both can be wrapped or combined with different material as well.
Crushed cartilage grafts can be used for the following purposes: (1) to cover the sharp edges of an irregular nasal framework after hump resection (2) to serve as an underlying padding material to prevent skin adhesion (3) to fill pit holes and, thus, mask irregularities (4) as a filler to mask asymmetries and depressions on the side walls (5) for tip grafting (6) to camouflage the edges of solid onlay grafts , (7) to supply minor dorsal augmentation for the correction of an overresected dorsum, and (8) to increase the thickness and natural color of the overlying skin where skin atrophy had occurred. I believe diced cartilage can be used in most of the above situations as well.

Our current clinical series confirmed our previous animal9 and human cell culture13 studies that the degree of crushing applied is important to the long-term clinical outcome of crushed cartilage grafts used in rhinoplasty.
The edges of solid onlay grafts might be softened by placing small pieces of moderately crushed grafts on or around the solid graft. The tiny pieces of moderately or significantly crushed grafts might be successfully used in final contouring at the conclusion of surgery. In patients with thin skin or in whom revision is required, a thin layer of moderately or significantly crushed cartilage would be the proper option as a padding material to prevent the adhesion of skin and to camouflage the sharp edges of the nasal skeleton that might be visible after edema has subsided.
From the above study, one would presume that thinner and smaller diced cartilage would also have higher resorption rates then thicker larger pieces, but I haven't seen any clinical studies to support or contradict that conclusion.
