Rhinoplasty for correction of a post-traumatic saddle nose deformity most commonly uses which type of graft?

• A Alloplastic silicone implant
• B Autologous costal cartilage or septal cartilage graft ✓
• C Cortical bone graft from iliac crest only
• D Acellular dermal matrix (AlloDerm)

Explanation

Saddle nose deformity (dorsal concavity from loss of cartilaginous or bony support) is most commonly corrected with autologous cartilage grafts — either septal cartilage (for minor defects) or costal cartilage (for larger reconstruction). Autologous tissue has the advantages of biocompatibility, integration, and durability without implant extrusion. Alloplastic implants carry risk of infection and extrusion. Iliac crest bone is used for bony dorsum reconstruction but has resorption issues. AlloDerm is used for soft-tissue augmentation, not structural support.
