Will my cartilage graft dissolve over time?

Probably not, and the numbers are reassuring. A meta-analysis pooling thirty-six studies and 2,526 patients found a resorption rate of one percent for grafts of your own rib cartilage. It is a real phenomenon rather than a myth, since cartilage has no blood supply of its own and depends on diffusion. But it is uncommon. So it is not the risk I would have you worry about. The same analysis reports warping at six percent, which makes bending roughly six times more likely than dissolving.

What is warping, and why does it matter more?

Warping is the slow curving of a graft that has survived perfectly well. Internal stresses locked within living cartilage are released when it is cut from the rib, and over months the graft bends toward the side that was carved away. A separate systematic review found that deviation and warping were the most common complication of autologous costal cartilage. So the graft does not fail by vanishing. It fails by moving, and it can take a straight nose with it. That is why I plan against bending first.

What is diced cartilage, and does it warp?

Cartilage cut into very small chips. Because a chip has no stress axis along which to curve, dicing does not merely resist warping; it abolishes the geometry that makes warping possible. I described a bone chip and diced cartilage graft for the nasal dorsum in a paper published in 2004, based on sixty-seven patients, most of them corrections of over-resected noses. The principle has held in the two decades since. So it is not a universal solution. Diced cartilage gives no rigid structural support and cannot replace a carved strut. But for rebuilding or smoothing a dorsum, it removes the commonest complication entirely.

Which cartilage do you prefer to use?

Whichever has the shape the nose is missing. Surgeons speak of a hierarchy of donor sites as though one were simply better, but they are chosen for geometry rather than durability. Septal cartilage is straight, firm and already in the nose, so it is my first choice whenever enough remains. Ear cartilage is naturally curved, which suits an alar rim and disqualifies it as a straight strut. Rib is the only source of real volume. So I reach for the rib when the nose needs strength nothing else supplies, not because rib lasts longest.

What do you do to protect the graft?

I preserve the perichondrium wherever possible, harvest and handle the cartilage atraumatically because crushed cartilage is dead cartilage, and carve under continuous irrigation so it never dries or overheats. I place it in a well-vascularized pocket, and in scarred revision tissue I wrap it in temporalis fascia to encourage tissue ingrowth. I also insist on smoking cessation, since nicotine constricts the vessels the graft depends upon. So most of this protects against warping as well as resorption. The same discipline serves both, which is why I describe a philosophy of care rather than promise a rate.

Is donor rib cartilage worse than my own?

Not straightforwardly, and I would be cautious of anyone who says so. Irradiated homologous cartilage is taken from a cadaver and sterilized, and it spares you a chest incision entirely. Compared directly in the meta-analysis, your own rib resorbs less, at one percent against three. Both warp at the same six percent. The authors conclude that current evidence does not demonstrate the superiority of either. So both are viable. The choice belongs to us together in consultation, weighed against your own priorities, rather than to a slogan.

What should I ask my surgeon?

Ask how the cartilage will be carved. Ask whether it will be taken from the center of the rib, whether the cross-sections will be balanced, and whether it will be left to sit and declare itself before it is placed. Those questions are more revealing than asking whether the graft will dissolve, because dissolving is the rarer problem by a factor of six. So a surgeon who has thought carefully about warping has almost certainly thought carefully about everything else. Their answer will tell you a great deal.

Why Cartilage Grafts Bend, and the Graft That Cannot

Dr. Nazmi Baycin, DHA-licensed board-certified plastic surgeon in Dubai

A cartilage graft is a piece of living tissue with no blood supply of its own, asked to hold a shape for the rest of a patient’s life. When patients in Dubai ask me what could go wrong with it, they almost always ask about the same thing: will it dissolve? It is a reasonable fear, and it is aimed at the wrong target.

I put it to every rhinoplasty patient in Dubai this way. Grafts of your own rib cartilage are reabsorbed in around one percent of cases. They bend in around six. The risk that keeps surgeons awake is not that the graft disappears but that it slowly curves, months later, taking a straight nose with it. This article is about what genuinely happens to cartilage after it is placed, why warping is the failure that matters, and what a surgeon can honestly do about both.

Key takeaways: the fate of a graft

Rib cartilage warps in 6% of cases and resorbs in 1%.
Warping is roughly six times more likely than dissolving.
Cartilage is avascular; it survives by diffusion from its bed.
Balanced carving is what resists bending, not the donor site.
Donor sites are chosen for shape: septum straight, ear curved, rib bulky.
Studies of cadaveric rib do not describe your own rib.

A note on scope: this article is about what becomes of a graft once it is placed. Why cartilage must be grafted at all — the over-resection that collapses a middle vault, and the spreader grafts that rebuild it — is the subject of my article on why some rhinoplasty results look unnatural, and what happens when septal cartilage loses its blood supply entirely in my article on septal perforation.

The wrong fear, and the right one

Cartilage has no blood vessels within it. It is nourished entirely by diffusion from the perichondrium, the thin membrane clinging to its surface, and from the tissue bed it is laid into. A graft cut off from both will die, be reabsorbed, and the volume it provided will vanish. That is resorption, and it is real.

It is also, with the patient’s own rib, uncommon. A systematic review and meta-analysis pooling thirty-six studies and 2,526 patients reports a resorption rate of one percent for autologous costal cartilage. The same analysis reports warping at six percent. A graft of your own rib is roughly six times more likely to bend than to disappear.

Nor is this an isolated finding. A separate systematic review of tip-stabilizing grafts found that deviation and warping were the most common complication of autologous costal cartilage. The graft does not fail by vanishing. It fails by moving.

Diagram titled cartilage grafts rarely dissolve, they bend, noting that patients are warned about the risk that seldom happens and not about the one that does. A section on what actually goes wrong with rib cartilage compares two failure modes. Warping, at six percent: the graft survives perfectly well and slowly curves, as internal stresses within the cartilage release over months, bending a straight strut, described as the commonest complication which deviates the nose. Resorption, at one percent: the graft is reabsorbed by the body and the volume it provided is lost, because cartilage has no blood supply and survives by diffusion, described as uncommon with your own rib but worth preventing anyway. A panel notes that pooled across thirty-six studies and more than two thousand five hundred patients, a graft of your own rib cartilage is roughly six times more likely to bend than to disappear. A section titled three sources chosen for shape rather than durability compares donor sites. Septum, straight and firm and already in the nose, is the first choice with no second wound anywhere on the body, but is limited in quantity and often already spent in a revision. Ear, naturally curved and springy, has a curve that is an asset for the rim and the nostril wall but which makes it useless as a straight strut. Rib, abundant and strong and restless, is the only source of real volume for a collapsed nose, but carries internal stress and a chest scar with it. A section on what a surgeon can genuinely control contrasts measures against bending, namely carving balanced cross-sections so opposing stresses cancel rather than curl the graft, taking cartilage from the center of the rib, and carving early then letting it sit and declare itself, noting warping is a property of the carving rather than of the patient; against measures against reabsorption, namely preserving the perichondrium that feeds it, handling gently because crushed cartilage dies, placing it in a well-vascularized pocket, and stopping smoking which starves the graft, noting a graft too far from blood cannot survive. A caution panel about donor cartilage explains that studies of cadaveric irradiated rib are sometimes offered as evidence that your own rib endures, but they are different materials, and compared directly the meta-analysis finds neither superior overall: your own rib resorbs less, the donor rib spares you a chest incision, and both bend at the same rate. The closing line reads ask your surgeon how the graft was carved, not whether it will dissolve.

Why warping, not resorption, is the failure mode that matters in cartilage grafting, by Dr. Nazmi Baycin, Dubai.

Why cartilage bends

Living cartilage is not inert. Internal stresses are locked within it, balanced against one another while it sits intact within a rib. Cut into that rib and the balance is broken. Over the following months the stresses release, and the graft curves toward the side that was cut away.

This is why the answer to warping lies in the carving rather than in the patient. I take cartilage from the central portion of the rib, where the stresses are most symmetrical. I carve balanced cross-sections, so that what remains is loaded equally on both faces and opposing forces cancel. And I carve early in the operation, then leave the graft in saline while I work elsewhere — because a graft that intends to warp usually begins to declare itself within the hour, and I would far rather discover that on the instrument table than a year later in a mirror.

There is a further answer, and I have some history with it. Cartilage diced into small chips has no stress axis along which to curve. Dicing does not resist warping; it abolishes the geometry that makes warping possible. I described a bone chip and diced cartilage graft for the nasal dorsum in a paper published in 2004, drawn from sixty-seven patients, most of them corrections of over-resected noses, and the principle has held in the two decades since: a graft with no grain cannot bend against it.

It is not a universal solution, and I would not present it as one. Diced cartilage provides no rigid structural support, so it cannot replace a carved strut where the nose must be held up rather than filled out. But where the task is to rebuild or smooth a dorsum, it removes the commonest complication from the table entirely.

Question	What patients ask	What the evidence shows	What I do
The main risk	Will it dissolve?	Resorption 1%, warping 6%	Plan against bending
Rib cartilage	The most durable	Durable, and the most restless	Carve it in balance
Donor rib	Inferior to your own	Neither proven superior	Judge case by case
Prevention	A better graft	Better handling and placement	Perichondrium and pocket

Three sources, chosen for shape

Surgeons speak of a hierarchy of donor sites, as though one were simply better. They are chosen for their geometry, not their durability:

Septal cartilage: straight, firm, already inside the nose, and requiring no second wound. It is the first choice whenever enough remains, and in a revision it often does not.
Auricular cartilage: naturally curved and springy. That curve is precisely why it suits an alar rim or a nostril wall, and precisely why it will not serve as a straight columellar strut.
Costal cartilage: abundant and strong, the only source of real volume for a collapsed dorsum. It also carries internal stress, and a scar on the chest.

So when I reach for the rib, it is because the nose needs volume and strength that nothing else can supply — not because rib is the graft that lasts longest. The choice is dictated by what the nose is missing, as I set out on my page about rhinoplasty in Dubai.

What protects a graft from being reabsorbed

Resorption may be uncommon, but it is not to be courted, and everything that prevents it follows from the fact that cartilage cannot feed itself. My protocol is unglamorous and it is the entire defense.

Preserve the perichondrium where possible, since it is the membrane through which nutrition arrives.
Harvest and handle atraumatically, because crushed cartilage is dead cartilage.
Carve under continuous irrigation, so the graft never dries or overheats.
Place it in a well-vascularized pocket, and in scarred revision tissue wrap it in temporalis fascia to encourage ingrowth.
Insist on smoking cessation, because nicotine constricts the very vessels the graft depends upon.

Notice that most of these protect against warping as well. Gentle handling, correct pocket, adequate blood supply: the same discipline serves both failures, which is why I would rather describe a philosophy of care than promise a rate.

A caution about donor cartilage

There is a second material in common use: irradiated homologous costal cartilage, taken from a cadaver and sterilized with radiation. It spares the patient a chest incision entirely, and its results are respectable.

I raise it because studies of that donor cartilage are sometimes cited as evidence that your own rib endures. They are different materials and the comparison does not transfer. When the two are actually compared in the meta-analysis, autologous rib resorbs less — one percent against three — while both warp at six percent, and the authors conclude that current evidence does not demonstrate the superiority of either. Both are viable. The choice belongs to the patient and the surgeon together, not to a slogan.

Ask a better question

When a patient in Dubai asks whether her graft will dissolve, I answer honestly — probably not, and here is what I do to make sure. Then I tell her what she has not asked, because it is the thing that will actually determine whether her nose is still straight in five years.

Ask how the cartilage will be carved. Ask whether it will be taken from the center of the rib, whether it will be balanced, whether it will be left to declare itself before it is placed. A surgeon who has thought carefully about warping has thought carefully about everything else. That is the standard I hold as an experienced plastic surgeon in Dubai, and it is a better question than the one about dissolving.
