Costal cartilage grafting in rhinoplasty has dramatically increased in popularity during the past decade, likely owing to many factors. With improved harvesting techniques and introduction of novel methods of using harvested cartilage, such as diced cartilage fascia grafts, the use of costal cartilage will likely continue to increase.1- 3 Augmentation rhinoplasty is becoming more popular and worldwide demand for the procedure is increasing in Asia and abroad. Augmentation cases require adding volume to the nose either in the form of an alloplastic implant or a biologic. Alloplastic implants have many potential problems such as infection, extrusion, and deformity. The consumer is driving a movement toward using their own autologous cartilage, with the most abundant source being costal cartilage. There is potential morbidity associated with harvesting autologous costal cartilage that may act as a deterrent for some patients using their own cartilage. An option is irradiated homograft costal cartilage.
