Caudal septal deviation correction by interlocked graft technique.

In this prospective study, we have proposed a new method to straighten the caudal septum using a modified spreader graft interlocked on the convex side. A single-interlocked graft inserted by 2 through-and-through serial sections of the quadrangular cartilage (applied over the misshapen convex side previously scored on the concave side) facilitated adjustment of the distal septum intraoperatively. The strip of cartilage of the desired height and width acted as a spring graft and may be placed at the desired height of the caudal septal area to exactly counteract the eventual tendency of the most deviated area to warp over time. All 15 patients treated had improvement of their nasal airway and in their postoperative appearance of the external and internal nose. Our technique is easy to perform and shows long-term reliability in correcting caudal septal deviation, demanding a wider application to confirm its effectiveness on a larger series of patients.
