Septal extension graft for correcting short nose in East Asians: review of autologous cartilage grafts and postoperative stability.

Septal extension grafts (SEGs) are widely used to correct a short nose in Asians, but few studies to our knowledge have investigated the relationship between different graft materials and the stability of the aesthetic results in East Asians. In this review we discuss the performance of autologous cartilage grafts, with a focus on the critical factors for achieving a stable postoperative nose shape, and propose algorithms for graft material selection in treating Asian patients. Avoiding harvesting septal cartilage grafts and preserving the whole cartilage is helpful for maintaining tip support over the long term. For patients who have loose nasal skin, a cartilage framework with no significant defect, or a mildly short nose, autogenous conchal cartilage is an effective and stable material for primary rhinoplasty. Costal cartilage has good performance and is suitable for treating severe nasal deformities and revision surgery.
