Quick answer
Peer-reviewed reviews suggest that irradiated homologous costal cartilage can have low pooled complication rates in rhinoplasty, while ADM can provide useful augmentation or camouflage in selected cases. These findings do not mean either material is universally appropriate or complication-free.
Different materials, different roles
Structural support and soft-tissue coverage are separate problems.
Irradiated homologous costal cartilage is processed donor rib cartilage. Surgeons may consider it when substantial structural graft material is needed and avoiding an autologous rib-harvest site is relevant. ADM is processed dermal tissue used in selected cases for augmentation, contour smoothing, graft coverage, or camouflage. Ear cartilage may be used for tipplasty because its curvature and thickness can suit specific tip tasks.
The fact that several materials appear in one operation does not mean they are interchangeable. Each should have a defined purpose based on anatomy, skin thickness, support requirements, prior surgery, and the surgeon's technique.
What published studies report
Complication rates are generally low in pooled studies—but the evidence has limits.
A 2022 systematic review and meta-analysis of 10 studies and 959 patients reported pooled complication estimates for irradiated homologous costal cartilage including warping, infection, resorption, displacement, extrusion, and revision. Another meta-analysis comparing autologous and homologous costal cartilage found no significant difference across several complication outcomes in the included retrospective studies.
A 2024 systematic review of ADM in rhinoplasty included 10 studies and 324 patients. It described high satisfaction and low rates for several complications, but partial or significant resorption was reported and techniques varied. These pooled results cannot predict an individual patient's outcome.
Risks to discuss
“Processed” does not mean risk-free.
- Infection or inflammatory reaction
- Warping, resorption, movement, or displacement
- Visibility, palpability, contour irregularity, or extrusion
- Under-correction, over-correction, or asymmetry
- Need for revision or graft removal
- General rhinoplasty risks, healing variability, and airway considerations
Material safety depends on more than the material name. Patient health, tissue coverage, aseptic handling, carving, fixation, surgical technique, and follow-up all influence risk.

What patients often ask
What is irradiated homologous rib cartilage?
It is donor costal cartilage processed and sterilized for implantation. It can provide structural graft material without creating a rib-harvest site in the patient, but it still carries graft-related risks.
What is acellular dermal matrix?
Acellular dermal matrix is processed dermal tissue with cells removed while a collagen-rich framework remains. In rhinoplasty it may be used for selected augmentation, contour smoothing, or camouflage roles.
Are these materials guaranteed to be safe?
No. Published studies report generally low complication rates in selected series, but infection, warping, resorption, displacement, extrusion, contour change, and revision remain possible. Study quality and techniques vary.
Why might ear cartilage still be used?
Ear cartilage has a natural curvature and may be useful for selected tip grafts or contouring. The appropriate material depends on the structural task, available tissue, skin coverage, and the complete surgical plan.
Is a one-week result final?
No. One-week images document early change while swelling, firmness, scar tissue, asymmetry, and tip definition are still evolving. Rhinoplasty requires longer-term follow-up.
