Zusammenfassung:This study describes a surgical technique for secondary unilateral cleft rhinoplasty using autologous costal cartilage grafts. The grafts were designed preoperatively and analysed three-dimensionally in 15 Asian patients using a photogrammetric camera. Detailed measurements of the nasal anatomy were taken both preoperatively and postoperatively; the same measurements were also taken from the pre-planned images of the anticipated result. When compared to the preoperative measurements, the postoperative three-dimensional outcome analysis revealed several statistically significant improvements in the nasal appearance: nasal dorsal length (P < 0.001), nasal column height (P = 0.001), nasal column width (P = 0.002), nasal lobule height (P = 0.008), cleft side nostril height (P < 0.001) and width (P < 0.001), columella–labial angle (P = 0.001), and nasal tip projection to nasal dorsum length ratio (NTP/NDL) (P = 0.001). Conversely, the comparison of the postoperative and preoperative design measurements showed mostly no statistically significant differences. Thus, utilizing autologous costal cartilage is a reliable approach with predictable and consistent results in secondary cleft rhinoplasty.
