From: Total nasal septal reconstruction using costal cartilage in difficult cases of secondary septoplasty
Figure 6. Schematic diagram of the technique. A: Reconstructed nasal septum with L-strut; B: collapse at the keystone area which may occur in L-strut due to inadequate suture fixation or failure of suture; C: C-shaped septal strut with two vertical limbs on both ends provides better stability; D: total septal plate replacement with costal cartilage graft. Multiple box sutures are used to hold the cartilage grafts together and prevent warping
