Diced cartilage has been widely applied in rhinoplasty, especially for segmental dorsal augmentation, with favorable outcomes over time. Various techniques were developed to increase both stability and viability of diced cartilage, including wrappings with non-blood material/blood products and changing the shapes of the diced cartilage, while the optimal technique is inconclusive. This article systematically reviews the current strategies of diced cartilage technique for rhinoplasty in the databases and emphasizes different wrapping materials. Free diced cartilage has a potential risk of gathering in certain regions and causing postoperative irregularities. Among non-blood wrapping materials, Surgicel is now rarely used due to severe foreign body reactions. The obvious drawbacks of fascia are donor site morbidity, inadequate quantity, and time-consuming. Although diced cartilage wrapped in tutoplast-processed fascia lata, AlloDerm, or esterified hyaluronic acid has achieved primary encouraging results, the increased inflammation raised controversies regarding their clinical use. Diced cartilage wrapped with blood products, such as platelet-rich fibrin or concentrated growth factor, achieved long-term reliable aesthetic results, and shaved cartilage and ultra-diced cartilage have recently shown satisfactory clinical outcomes, while further study is still needed.
