Cartilage Grafts in Rhinoplasty: Why They Are Used and Where They Come From
Cartilage grafts are among the most important tools in modern rhinoplasty. Rather than simply removing tissue to make a nose smaller, contemporary rhinoplasty often uses cartilage to strengthen weak areas, refine shape, support the tip, maintain breathing, or rebuild a nose that has lost structure from prior surgery or trauma.
Why grafts are needed
The nose is a three-dimensional structure that must remain both attractive and stable. In some patients, existing cartilage is strong enough to support planned changes. In others, especially in revision rhinoplasty, the surgeon needs additional cartilage to rebuild the bridge, reinforce the nasal valves, correct asymmetry, or create durable tip support.
Cartilage grafts are particularly valuable when a previous operation has removed too much support. They may also be used in patients with naturally weak cartilage, a significantly deviated nose, traumatic deformity, or a need for major dorsal augmentation.
Common sources of cartilage
The source of cartilage is chosen according to the amount required, the purpose of the graft, the patient's anatomy, and whether prior surgery has already used available septal cartilage
Septum: Primary rhinoplasty and small to moderate support grafts. Often preferred when enough native septal cartilage is available.
Ear: Curved or flexible grafts and selected tip or nostril reconstruction. Useful when a modest volume of cartilage is needed.
Rib: Major reconstruction, strong support, dorsal augmentation, and complex revision surgery.Provides the greatest volume and strength when septal cartilage is limited.
Donor rib cartilage: Donor rib cartilage. Selected reconstructive cases. May avoid a chest harvest; graft choice depends on surgeon and patient factors.
Cartilage from the patient's own body has long been an important reconstructive material because it provides both volume and structural support. Rib cartilage is especially useful when major support or augmentation is required and adequate septal cartilage is unavailable.
What grafts can do
A graft may be used to straighten a crooked nose, improve bridge contour, support a weak middle vault, prevent or correct valve collapse, improve tip definition, or rebuild an over-resected nose. The exact shape and placement of each graft are tailored to the problem being addressed.
For example, spreader grafts can widen and stabilize the internal nasal valve region. In a revision case, structural grafts may restore lost height, improve sidewall support, and create a more stable foundation before aesthetic refinements are made.
Is rib cartilage safe?
Rib cartilage is often considered when a revision case requires more support than the septum or ear can provide. As with any graft source, there are specific risks and benefits to discuss. The choice depends on how much cartilage is needed, where it will be placed, and the degree of strength required for a stable long-term result.
The best material is the one that provides the right balance of strength, shape, quantity, and long-term stability for the individual patient's anatomy and surgical plan.
