    Abstract:
    BACKGROUND: Saddle nose deformity presents a significant challenge to surgeons. The reconstruction of a saddle nose requires structural addition to the nasal dorsum and tip. Costal cartilage grafts have been utilized for fixing severe saddle nose deformity, but costal cartilage is notorious for early and/or late warping. In addition to well-known measures, the efficacy of a preventive surgical technique against warping was investigated in this study. METHODS: Costal cartilage grafts were used in 18 patients with severe saddle noses. Due to recurrent and late warping of the grafts, an additional measure was taken in 23 patients with a comparable deformity. In these 23 patients, just before insertion the costal cartilage was transected on 75 % of its horizontal width every 2 mm, alternating between both sides along the entire length of the implant, a so-called "accordion technique." RESULTS: With traditional measures early and/or late warping of the graft was observed in 7 (39 %) of 18 patients postoperatively. Two grafts warped so severely that they required revision surgery. On the other hand, additional use of the accordion technique prevented the costal cartilage from warping in all 23 cases. The warping complication rate was significantly higher in patients whose graft did not undergo the described accordion technique. CONCLUSIONS: The accordion technique is thought to break the recoil mechanism responsible for warping. Since incorporating this surgical technique, warping has not been seen in any saddle nose deformity patients treated by us in the last 5 years. This simple technique is strongly recommended in these cases. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.
