Warping — where a carved piece of rib cartilage gradually curves or twists due to internal tension released during harvesting — is a well-documented consideration in rib cartilage rhinoplasty, with published research placing the overall rate at roughly 3-10% depending on the technique used. Several established methods reduce this risk, including balanced cross-sectional carving (removing equal amounts from opposite sides of the graft), allowing the cartilage to rest before final shaping, and using finely processed or diced cartilage rather than a single large carved piece, since smaller, more uniform pieces carry far less internal tension to release.
Dr. Kim applies these principles as standard practice, selecting the specific anti-warping approach based on the size and location of the graft your case requires.
Consultation Tip
Ask which anti-warping technique will be used for your specific graft — a surgeon who can answer this specifically, rather than generally, is demonstrating genuine technical attention to this detail.
