Abstract
Background: Dorsum augmentation is one of the most delicate components of rhinoplasty. Most recently, diced cartilage has gained acceptance in nasal reconstruction as an optimal material. Its biocompatibility, availability, pliability and lower risk of infection/extrusion when compared with alloplastics make it the best choice for volume augmentation.
Objective: To assess the use of diced cartilage in dorsal reconstruction of the nose and evaluate its efficacy.
Patients and Methods: The pertinent role of diced cartilage in autologous dorsal nasal augmentation has been popularized over the past decade. With this technique, rib, conchal, or septal cartilage is harvested, diced into small fragments (0.5-1 mm), and subsequently placed on the nasal dorsum for appropriate augmentation as free diced cartilage, wrapped in or covered with fascia, wrapped in Surgicel or Allo-derm or with its perichondrial attatchment. In this systematic review and meta-analysis, the included studies are 15 in number with total 1308 patients.
Results: Multiple techniques of diced cartilage in dorsal reconstruction in rhinoplasty were assessed as regarding cosmetic appearance (patient satisfaction) which achieved in 94.1%, graft resorption 1.8% of all patients, over or undercorrection 2.1%, persistent irregularities 1.2% and requiring revision 4.4% of all cases.
Conclusion: Diced cartilage technique is an attractive option for use in rhinoplasty especially in augmentation procedures as it is simple to use, quicker, aesthetically superior to solid cartilage grafts without any risk of warping and minimal risk of graft resorption.
