The use of graft materials in rhinoplasty presents many challenges for the surgeon. There are a wide variety of alloplastic materials available for nasal augmentation but the graft material of choice remains autologous cartilage. It has considerable advantages over alloplasts. It does not induce an immune response and has a very much lower rate of infection or extrusion. It is also easily harvested and sculpted and is available in plentiful supply. We present a retrospective review of 103 patients who underwent augmentation rhinoplasty using autologous cartilage grafts with a mean follow-up time of three years six months. The revision rate over the follow-up period was 15.5 per cent (n = 16). The same surgeon's revision rate for rhinoplasty without graft over the same period was four per cent in 311 cases. We conclude that while autologous cartilage remains the best graft material available there is a significantly higher revision rate than when no graft is required. This is primarily due to the unpredictable scarring associated with the graft in the medium term and the asymmetric nature of conchal cartilage.
在鼻整形术中使用移植材料给外科医生带来了诸多挑战。有多种异体材料可用于鼻整形术隆鼻，但首选的移植材料仍是自体软骨。与异体材料相比，它有相当多的优势。它不会引发免疫反应，感染或排斥率也低得多。它还易于获取和塑形，且供应充足。我们对103例行自体软骨移植隆鼻术的患者进行了回顾性研究，平均随访时间为三年零六个月。随访期间的修复率为15.5%（n = 16）。同期，同一位外科医生行无移植鼻整形术的311例患者的修复率为4%。我们得出结论，虽然自体软骨仍是现有的最佳移植材料，但与无需移植时相比，其修复率明显更高。这主要是由于中期与移植相关的不可预测的瘢痕形成以及耳甲软骨的不对称性。
