Objectives: To advance and refine the use of rib cartilage in nasal augmentation by developing a technique that minimizes the risk of cartilage warping in both the short and long term. This study aims to establish a more structurally stable and reliable approach to rib cartilage grafting, enhancing both aesthetic and functional outcomes in open rhinoplasty. Introduction: Cartilage warping remains a persistent challenge in open rhinoplasty, often compromising both aesthetic results and structural integrity. While various techniques have been proposed to mitigate this issue, a consistently reliable solution has yet to be established. This study presents a novel surgical approach developed by Dr. Teerasut Wattanajindaporn to prevent warping of rib cartilage used for dorsal augmentation. The technique has been clinically applied in surgical cases, with both short- and long-term follow-ups demonstrating promising stability and graft integration. Materials / method: This study introduces a spring-shaped carving technique designed to improve the stability of rib cartilage grafts in open rhinoplasty. The technique involves using a scalpel to precisely sculpt rib cartilage into a spring-like configuration, allowing for controlled flexibility and curvature while minimizing the risk of postoperative warping. This modification ensures that the cartilage adapts naturally to nasal contours while maintaining its structural integrity. The technique was applied in clinical cases with short- and long-term follow-ups to assess its effectiveness. Results: This study is based on clinical observations and practical application rather than statistical analysis. The findings suggest that the spring-shaped carving technique enhances graft stability and reduces the likelihood of cartilage warping in rib cartilage grafting for open rhinoplasty. Conclusion: This study highlights the benefits of the spring-shaped carving technique for rib cartilage grafting in open rhinoplasty. It enhances flexibility and stability while minimizing warping, ensuring natural conformation to the nasal dorsum. Despite being based on clinical observations, consistent outcomes suggest its reliability for long-term contour stability. Further research is needed to validate its efficacy, especially in complex and revision cases, contributing to the advancement of rhinoplasty techniques.
