Whistling nose: when the septum is perforated
A whistle with every breath in, louder during exercise or at night: this is the typical symptom of a small perforation at the front of the septum. It is annoying, rarely dangerous, and it can be dealt with.

In brief
The whistle comes from air rushing from one nostril to the other through a small hole, especially at the front of the septum.
A whistle that stops without treatment is not necessarily good news: the hole may have grown and should be measured.
Local care rarely quietens it; the 2026 consensus lists whistling among the reasons to offer surgical closure straight away.
Why a perforated septum whistles
Normally, air flows through two separate corridors. When the septum has a hole, some air crosses from one corridor to the other. If the opening is narrow, the air speeds up, the edge vibrates and the nose whistles, like a kettle or a window left ajar on a windy day.
The whistle is often louder when breathing in, during exercise, when speaking or at night with a clear nose. It commonly comes with crusts at the edge of the hole and small bleeds: air hitting the same edge again and again dries it out.
What matters: the size and position of the hole
Small perforations whistle, large ones much less: air passes through without being squeezed into a bottleneck. Position matters just as much. The 2026 consensus notes that perforations at the front are generally more troublesome than those at the back of the nose, which are sometimes found by chance.
Circles drawn in proportion. These are rough guides: no study sets a precise threshold, this is the pattern ENT surgeons describe. A perforation may also whistle only at times, depending on the crusts narrowing it.
A whistle that stops by itself
- The hole may have grown: beyond a certain size, air no longer whistles, but crusting and dryness increase.
- A crust can temporarily block the opening; the whistle returns when it falls off, often with a bleed.
- Either way, ask for a new endoscopic measurement and compare it with the previous one.
Keeping your measurements in millimetres from one check-up to the next is the only way to know whether the perforation is changing.
Can a nose whistle without a perforation?
Yes. Crusts, thick mucus or a narrowing at the entrance of the nose can also produce a whistle. But in someone who has had nasal surgery, uses a spray long term or often picks their nose, a perforation is the first thing to look for.
The examination is simple: an ENT surgeon sees it within a minute with an endoscope, sometimes with just a light. Ask for its exact size, length and height, and its position. To find the cause, see Causes.
What stops the whistle
Not every option has the same effect on the noise. Local care remains essential for crusting, but it rarely stops the whistle, since the hole is still there.

What the 2026 consensus says
Why surgery can be offered straight away
As a rule, the experts recommend starting with medical care before discussing surgery. They name three exceptions where closure can be offered from the outset: younger patients, exposed cartilage at the edge of the hole, and whistling.
The reason is simple: whistling hardly ever responds to local care, it affects sleep, voice and social life, and it usually signals a small perforation at the front, in other words a hole that can be closed in good conditions. The longer you wait, the more it may grow.
To measure how much it bothers you before the appointment, the consensus recommends the NOSE-perf questionnaire: our self-assessment gives you a score to show your ENT surgeon. To find a team, see the surgeon directory.
Frequently asked questions
Why does my nose whistle when I breathe?
Most often, air crosses from one nostril to the other through a small perforation at the front of the septum, and the edge of the hole vibrates. Crusts or a narrowing can whistle too; an ENT surgeon tells them apart in a minute with an endoscope.
Is a whistling nose serious?
The whistle itself is not dangerous, but it almost always signals a hole that should be measured and whose cause should be found. It often comes with crusting and bleeding, which can make the perforation bigger.
Does a septal button stop the whistle?
Yes, while it is in place, because it plugs the hole. But it is a foreign body that needs regular care, and the consensus reserves it for patients who cannot or do not want to have surgery.
