Economizing the Septal Cartilage for Grafts During Rhinoplasty, 40 Years' Experience.

[BACKGROUND] During rhinoplasty, it is typically necessary to use cartilage to shape and support the final nasal construct to provide both form and function to the nose (Tanna et al. in Plast Reconstr Surg 141(1):137e-151e, 2018; Guyuron in Plast Reconstr Surg 105(6):2257-2259, 2000; Kim et al. in Ann Plast Surg 65(6):519-523, 2010). The septal cartilage is the ideal graft both for its ease of access and quality of cartilage. However, this graft is a limited resource, and economy of its use is important as to negate the need to harvest cartilage from the ear or rib.

[THE PURPOSE] 1. To share the senior author's 40 years' experience with the economy of septal cartilage. 2. To identify the areas of the septal cartilage most suitable for a particular graft. 3. To discuss the common grafts that are used in rhinoplasty. 4. To identify when other sources of cartilage are needed and where to best use those grafts. 5. To present option for preservation of the leftover septal cartilage.

[CONCLUSION] Overall consideration should focus on the size, thickness, and curvature of the graft contemplating the structural and functional needs of the rhinoplasty maneuvers.
