Of all the things that can go wrong in nasal surgery, a septal perforation is the one I find hardest to forgive — because it is almost never bad luck. In more than 25 years of nasal surgery in Dubai I have come to regard it not as a risk to be accepted but as a technical failure to be avoided, and the distinction matters enormously to anyone considering an operation on their nose.
The hole does not appear where the surgeon cut. It appears where the blood supply was taken away — a point I make to every nasal surgery patient in Dubai before we begin. Understanding that single mechanism explains why perforations happen, why they are preventable, and why repairing one is so much harder than never causing it. This article sets out all three, and it also corrects some confident claims — including ones I have seen made about my own field — that the evidence does not support.
Key takeaways: perforation and its repair
- Cartilage is fed by the lining on each side; strip both and it dies.
- Most perforations are made in the operating room, not suffered.
- A single tear rarely perforates; two opposing tears usually do.
- Symptoms are real: crusting, bleeding, whistling, obstruction.
- Modern repair succeeds in more than nine cases in ten.
- There is no standard technique and no settled graft material.
A note on scope: this article is about the septal lining and what happens when its blood supply is lost. Why over-resecting cartilage produces an operated-looking nose is a separate subject, covered in my article on why some rhinoplasty results look unnatural, and the bony vault and its osteotomies in my article on the path of the lateral osteotomy.
The cartilage starves; it does not tear
The septum is a sandwich. At its center lies a plate of cartilage, and pressed against each face of that plate is a layer of lining — mucosa carried on a thin membrane called perichondrium. The cartilage has no blood vessels of its own. Every nutrient it receives arrives by diffusion from those two linings.
Lift the lining from one side and the cartilage survives comfortably on the other. Lift it from both sides at the same point, or tear both linings opposite one another, and the cartilage between them becomes an island cut off from its supply. It does not tear or fracture. It quietly necroses over the following weeks and sloughs away, and where it stood there is now a hole through the middle of the nose.

Four ways a surgeon causes one
Perforations following nasal surgery are overwhelmingly iatrogenic — caused by the operation. In a recent series of seventy-four repairs, prior nasal surgery was the single commonest cause of the perforations treated, accounting for 42 percent of them. That is an uncomfortable statistic, and it should be. The technical missteps that produce them are well known:
- Tearing dissection: sharp, impatient elevation rather than a slow sweep in the correct plane beneath the perichondrium.
- Over-resection: removing cartilage without preserving a strong L-shaped strut, so the septum collapses and the lining is put under tension.
- Thermal injury: liberal electrocautery that chars precisely the tissue you are relying on to heal.
- The unrepaired tear: noticing a breach in the lining and leaving it, rather than closing it there and then.
Notice that the last of these is not a failure of skill but of discipline. A single tear on one side, repaired immediately, almost never perforates — the opposite lining still feeds the cartilage. It is the second tear, sitting directly opposite the first, that seals the fate of the cartilage between them.
What prevention actually looks like
My protocol follows from the mechanism rather than from habit. I inject saline beneath the perichondrium first, floating the lining away from the cartilage and opening a bloodless plane that can be swept rather than cut — hydrodissection. I work under illumination good enough to see individual fibers, because a plane you cannot see is a plane you will tear.
Any breach in the lining is repaired the moment it occurs, with fine absorbable suture, before I continue. This is the discipline I hold to in every nasal operation I perform in Dubai. And I keep a mental map of where the lining has been thinned or opened on each side, because the one thing I will not permit is two defects facing one another across the cartilage. Electrocautery is used sparingly and precisely. None of this is glamorous, and all of it is the reason the complication remains rare.
Why a hole is not a trivial thing
Patients sometimes imagine a perforation as a cosmetic irrelevance hidden inside the nose. It is not. Air that should glide smoothly across the lining now tumbles through the gap in turbulent eddies, and turbulent air dries mucosa. Dried mucosa crusts, and crusts bleed when they separate.
So the perforation sustains itself: drying, crusting, bleeding, and a sense of obstruction that seems paradoxical given the extra opening. Many patients whistle audibly when they inhale — a small, constant, humiliating reminder. It is a genuine burden on daily life, and it is why repair is offered when symptoms warrant it.
Repair: three layers, not one hole
The mistake in thinking about repair is to picture patching a hole in a wall. The septum is not a wall but a sandwich, and a repair that does not restore all three layers will fail. Two opposing linings must be mobilized as flaps, advanced, and closed without tension — and between them a graft is laid.
That graft is not a plug. It is a scaffold, whose purpose is to interrupt the wound’s natural tendency to contract and pull the closure apart again. Where local lining is insufficient — in large defects, or after failed repairs — tissue with its own blood supply can be brought in, such as a flap raised from the inferior turbinate. Bringing living blood supply to a stubborn wound is the oldest principle in reconstructive surgery, and the most reliable.
| Question | Confident claim | What evidence shows | My position |
|---|---|---|---|
| Cause | An accepted risk | Mostly prior surgery | A preventable failure |
| Success rate | Around 65–90% | Above 90%; 95% in a recent series | Quote the modern figure |
| Best technique | One gold standard | No standard approach exists | Match it to the defect |
| Graft material | Cartilage is essential | Dermis achieved 95% closure | Distrust certainty here |
Where surgical opinion outruns the evidence
Here I want to be careful, because this is a field in which surgeons state preferences as though they were findings. I have read confident assertions that fascia and acellular dermis lack the rigidity to resist wound contraction, and that rigid cartilage is therefore indispensable. It is a persuasive argument. It is not what the data show.
A review of seventy-four septal perforation repairs reported closure in ninety-five percent of patients, with breathing scores improving in seventy-eight percent of them — and in ninety-seven percent of those cases the interposed material was cadaveric dermis, not cartilage. Mean follow-up was seven and a half months, so it speaks to closure rather than to durability over years. Meanwhile a state-of-the-art review of perforation repair concludes that success now exceeds ninety percent, while stating plainly that no standard approach or single technique exists, and that the highest success is seen with pedicled flaps carrying their own arterial supply.
I use rigid cartilage where the defect and the tissue favor it, and I would defend that choice. What I will not do is present my preference as settled science. The honest summary is that several materials work in competent hands, that the flap and its blood supply probably matter more than what lies between them, and that any surgeon entirely certain about graft material is telling you about themselves rather than about the evidence.
Repair belongs inside a whole-nose plan
A perforation seldom sits in isolation. It commonly accompanies loss of septal support, a saddling dorsum, or collapse of the internal valve — because whatever destroyed the lining often weakened the framework too. Closing the hole while ignoring the collapsed structure around it produces a nose that is intact and still does not work.
So I address the septum, the support, and the airway as one operation rather than three. My approach to the septum itself is described on my page about septoplasty in Dubai, and this integrated thinking is the standard I hold at my plastic surgery clinic in Dubai.
The repair never needed
Septal perforation repair is among the most demanding operations in nasal surgery, and modern results are genuinely good. But every successful closure I perform is the correction of something that should not have occurred.
The work I am proudest of here is invisible: the perforations that never formed, because the plane was floated open rather than torn, and because no two defects were ever allowed to face each other across the cartilage. That is not artistry. It is discipline.
FAQs about septal perforation in Dubai
-
What actually causes a septal perforation after surgery?
The cartilage in the middle of your septum has no blood vessels of its own. It is fed entirely by diffusion from the lining pressed against each of its two faces. If both linings are lifted or torn at the same point, the cartilage between them is cut off from its supply. It does not tear. It slowly dies over the following weeks and sloughs away, leaving a hole. So the hole appears where the blood supply was lost, not where the surgeon cut. That single mechanism explains almost every perforation that follows nasal surgery.
-
Is a perforation just bad luck?
Rarely, and I say that plainly. Perforations following nasal surgery are overwhelmingly caused by the operation itself, and in a recent series of seventy-four repairs, prior nasal surgery was the commonest cause of the perforations being treated, at forty-two percent. The usual missteps are known: tearing dissection rather than a patient sweep, resecting cartilage without leaving a strong strut, liberal cautery, and leaving an intraoperative tear unrepaired. So I regard it as a preventable technical failure rather than an accepted risk. Framing it as bad luck lets the wrong lesson be drawn.
-
What happens if my surgeon tears the lining during surgery?
A single tear on one side, repaired immediately, almost never leads to a perforation. The lining on the opposite face continues to feed the cartilage perfectly well. The danger is the second tear, sitting directly opposite the first. That is what strands the cartilage between them without a blood supply. So what matters is not whether a tear occurs but whether it is closed at once, and whether two defects are ever permitted to face one another. I keep a mental map of both sides throughout.
-
What symptoms does a perforation cause?
Air that should glide smoothly across the lining now tumbles through the gap in turbulent eddies, and turbulent air dries the mucosa. Dried mucosa crusts, and crusts bleed when they separate. The result is a self-sustaining cycle of drying, crusting, and bleeding, together with a sense of obstruction that seems paradoxical given the extra opening. Many patients whistle audibly on breathing in. So it is not a cosmetic irrelevance hidden inside the nose. It is a genuine daily burden, and that is when repair becomes worth its difficulty.
-
How successful is septal perforation repair?
Considerably more successful than older figures suggest. A state-of-the-art review concludes that repair has moved from being a discouraged operation to one succeeding in more than ninety percent of cases. A recent review of seventy-four repairs reported closure in ninety-five percent of patients, with breathing scores improving in seventy-eight percent of them, at a mean follow-up of seven and a half months. So I would be wary of any surgeon quoting the old sixty-five to ninety percent range. Modern technique and modern reporting both do better than that.
-
Which graft material is best?
Nobody honestly knows, and I think you should be told so. You will hear confident arguments that only rigid cartilage resists wound contraction, and that fascia or acellular dermis is inadequate. The evidence does not bear that out. In the seventy-four-case review with ninety-five percent closure, ninety-seven percent of repairs used cadaveric dermis rather than cartilage. Reviews of the field find no standard technique and no settled material. So I use rigid cartilage where the defect favors it, and I defend that choice, but I will not dress a preference as a finding. The flap and its blood supply likely matter more than what lies between.
-
Can every perforation be repaired?
Not every one, and size is only part of the picture. What matters is how much healthy lining remains above and below the defect, since that is the tissue I must recruit to close it. For large or previously failed perforations, local lining may be insufficient, and I bring in tissue that carries its own blood supply, such as a flap raised from the inferior turbinate. So the question I ask is not how big the hole is but how much living tissue surrounds it. Bringing new blood supply to a stubborn wound remains the most reliable principle we have.
-
Will repairing the hole fix my breathing?
Usually it improves substantially. In the recent seventy-four-case review, breathing scores improved in seventy-eight percent of patients after closure. But a perforation rarely sits alone. Whatever destroyed the lining often weakened the framework too, so collapse of the internal valve or loss of septal support may coexist. So I address the septum, the support and the airway together rather than closing the hole in isolation. A nose can be made intact and still not work, and that is not an outcome I would accept for you.
