While there is not necessarily a 'best' donor cartilage for structural nasal grafting, I generally prefer nasal septal cartilage. Septal cartilage, when properly harvested during
rhinoplasty, is usually plentiful in supply, straight and rigid. There is essentially no donor site morbidity as it comes from the same surgical field that is being worked on already. When septal cartilage is unavailable (previous septal surgery, trauma, drug abuse, etc.), I prefer costochondral (rib cage) cartilage to other sites (ie. ear) as it is perfect for structural grafting in the nose. The only disadvantage in my view is the additional surgical site which in my experience has been only minimally inconvenient for patients. Choosing the right cartilage is all about the nasal requirements. As none of the available donor sites are all that bad for patients to deal with, I prefer to go with the 'best available.' In my practice, there are only very rarely indications for 'onlay' grafting which typically is utilized to 'fill in' visible defects. These grafts are usually crushed or morselized to prevent warping and can be from any donor source. Unfortunately, onlays can resorb or shift. In my secondary and reconstructive
rhinoplasty practice in particular (but often in primary
rhinoplasty as well), I find structural grafting is essential to maintain the nasal size, shape and orientation. As my
rhinoplasty practice has evolved over 15 years, I have moved toward structurally grafting nearly all of my patients and my results have improved and become more sustainable as a result.
