To achieve the desired nasoseptal refinements in septorhinoplasty, sufficient septal cartilage is needed. There are many cases in which septal cartilage is insufficient, especially in revision surgery. To obtain an optimal outcome, a bony cartilaginous unit is proposed as a versatile graft for various parts of the nose. This bony cartilaginous unit is extracted using the open septorhinoplasty approach in which the bilateral septal flaps are elevated over the entire cartilaginous and bony part; however, the cartilaginous septum and posterior bony part are not separated and are removed as an integrated unit. These bony cartilaginous units can be used as various types of grafts at different sites in the nose. In the present study, the bony cartilaginous units were used as caudal extension grafts, spreader grafts, lateral crural strut grafts, and for the closure of septal perforations. This research has shown the advantage of using septal bone in conjunction with cartilage as an integrated unit to correct external nose and septal deformities, especially in cartilage-depleted patients.
