Do Nasal Strips Help With a Deviated Septum? (2026)

A deviated nasal septum is one of the most common reasons adults experience persistent nasal obstruction, snoring, and disturbed sleep. It is also one of the most common reasons people reach for a nasal strip and feel disappointed when the box of strips does little or nothing. The honest answer to whether nasal strips help with a deviated septum is that they sometimes help, partially, in mild cases — and that they do not address the actual structural problem at all.

This article explains, from an ENT perspective, what a deviated septum is, why a strip can or cannot reach the obstruction, who is likely to feel some relief, and when to stop relying on over-the-counter devices and seek evaluation.

Key takeaways

• A deviated septum is a structural deformity of the wall between the two nasal cavities. It cannot be corrected by any external device.
• Nasal strips act on the soft outer cartilage of the nose, not on the septum. Their effect on septal obstruction is indirect at best.
• In mild deviation, where the dominant symptom is nasal-valve narrowing on the same side, a strip can produce partial relief.
• In moderate to severe deviation with persistent unilateral blockage, strips usually feel like they do nothing.
• The Cottle manoeuvre is a useful at-home test to predict response.
• Persistent unilateral obstruction, recurrent sinus infections, or symptomatic snoring deserve ENT evaluation. Septoplasty is the definitive treatment when conservative measures have failed.

What a deviated septum actually is

The nasal septum is the wall of cartilage and bone that divides the inside of the nose into a left cavity and a right cavity. In a perfectly straight septum, the two cavities would be roughly equal. In reality, almost no septum is perfectly straight — minor deviations are present in a large majority of adults and most produce no symptoms at all.

A clinically significant deviated septum is one in which the wall bends far enough to one side to narrow the airway on that side, causing persistent obstruction, mouth breathing, snoring, recurrent sinusitis, or related symptoms. Deviations are usually present from birth or develop after nasal trauma — a fall, a sports injury, or a road traffic accident. Many patients cannot recall a specific event and discover the deviation only when symptoms appear in adulthood.

The cardinal feature of symptomatic septal deviation is persistent, predominantly one-sided nasal obstruction. The patient often reports they have always had a "blocked side". They may sleep facing one direction because it breathes better. They may need to switch sides when one nostril runs out of airflow.

Why a nasal strip cannot fix a deviated septum

A nasal strip applies outward tension to the skin of the bridge of the nose. The springy band beneath the adhesive pulls the outer walls of the nostrils very slightly outward, widening the nasal valve — the narrowest point at the front of the nose. This is the entire mechanism of the device.

The septum, by contrast, sits in the middle of the nose, deeper inside, and is made of firm cartilage anchored to bone. No amount of external skin tension reaches it. A strip cannot move it, straighten it, or compensate for it [1].

This is why patients with significant septal deviation almost always report that nasal strips "do nothing". They are correct: the device is doing exactly what it always does, but at the wrong level of the airway.

When a strip might still help, a little

There is one specific scenario in which a strip can produce partial relief in a person with septal deviation. If the deviation is mild, and the patient's dominant symptom comes from co-existing narrowing at the nasal valve on the same side, widening the valve can improve airflow enough to be noticeable.

This is most often the case in patients with the following profile. The deviation is described by an ENT as mild on examination. The patient experiences variable rather than fixed obstruction — sometimes the side breathes well, sometimes poorly. Symptoms worsen with allergic flares or congestion, when mucosal swelling adds to the underlying narrowing. The Cottle manoeuvre, described below, produces clear improvement.

In these patients a one-week trial of a correctly applied standard adhesive strip is reasonable. The improvement, when it occurs, is usually partial — the side breathes better but is not fully clear, and snoring is softer but not absent.

The Cottle manoeuvre: a useful home test

Before spending money on strips for a suspected septal problem, perform the Cottle manoeuvre. Stand in front of a mirror. Place a fingertip on the cheek beside the affected nostril and gently pull the skin of the cheek outward, away from the centre of the face. Breathe in.

If the obstructed side feels noticeably more open with the cheek pulled outward, the nasal valve is contributing to the obstruction, and a nasal strip is likely to help at least partially. If the manoeuvre produces no improvement, the obstruction is deeper inside — most likely at the septum or further back — and a strip is unlikely to be effective.

The test takes ten seconds and is a more reliable predictor of strip response than any product claim on the packaging.

What about Breathe Right strips specifically?

The most-asked branded version of this question — "do Breathe Right strips help with a deviated septum?" — has the same answer. Breathe Right is the original external nasal dilator and the most studied brand on the market [2]. It is well made and consistent, but its mechanism is identical to other adhesive strips. It cannot straighten the septum any more than a generic strip can. Brand selection in this scenario does not change the underlying mechanical reality.

When to stop trying strips and see an ENT

Persistent obstruction that does not respond to a properly conducted strip trial, decongestants, allergy treatment, and saline irrigation deserves formal ENT assessment. The features that should prompt a clinic visit include the following.

One-sided nasal obstruction lasting more than several weeks, especially if it is constant rather than intermittent.

Recurrent episodes of acute sinusitis, particularly affecting the same side each time.

Loud or irregular snoring, witnessed pauses in breathing, gasping arousals, unrefreshing sleep, or daytime sleepiness. These features raise the possibility of obstructive sleep apnoea, which has a substantially increased risk of cardiovascular events and stroke when untreated [3] and may require a formal sleep study [4].

A history of nasal trauma followed by ongoing obstruction.

Nosebleeds from the same side, particularly from a visible spur or sharp ridge in the septum.

An ENT examination uses a nasal endoscope and anterior rhinoscopy to determine where the obstruction is, whether it is septal, turbinate, valve, or polyp-related, and what the appropriate treatment is.

Treatment options for symptomatic septal deviation

Conservative measures are tried first in most patients. These include intranasal corticosteroid sprays, saline nasal irrigation, allergen avoidance where relevant, and a structured trial of nasal strips if the Cottle manoeuvre is positive.

When conservative measures fail and symptoms remain disruptive, the definitive treatment is septoplasty — a surgical procedure to straighten the septum. Septoplasty is usually performed under general anaesthesia as a day-care or short-stay procedure. Recovery typically takes one to two weeks. The procedure is reliable for relieving fixed obstruction caused by the septum itself, although it does not treat associated allergic rhinitis or turbinate hypertrophy, which are usually managed together where present.

In some patients with both septal deviation and enlarged inferior turbinates, septoplasty is combined with turbinate reduction in the same operation.

Common questions

Will nasal strips help my deviated septum if I have one?

Only partially, and only if the deviation is mild and the symptom comes partly from the nasal valve. In moderate to severe deviation, strips are unlikely to make a meaningful difference.

Will the strip eventually loosen or straighten my septum if I use it every night?

No. The strip exerts a small outward pull on the skin of the bridge of the nose. It does not remodel cartilage. There is no published evidence of any long-term structural change from nightly use.

Is septoplasty the only fix?

Septoplasty is the definitive surgical fix for a deviated septum that is causing significant fixed obstruction. Conservative measures — sprays, irrigation, allergy management, and a trial of strips — are reasonable first steps and resolve symptoms for many patients.

My partner says I snore from one side of the nose. Is that the septum?

It may be. Predominantly one-sided snoring or breathing difficulty, especially if it has been present for a long time or began after a nasal injury, is suggestive of septal deviation and is worth an ENT evaluation.

Can I use a strip after septoplasty?

Generally yes, but not in the immediate postoperative period. Discuss timing with your surgeon. Strips are not a substitute for following postoperative care instructions.

Bottom line

A nasal strip cannot fix a deviated septum and is not a treatment for one. It is a small external device that widens the nasal valve. In mild deviation accompanied by nasal-valve narrowing, a strip can produce partial relief and is a reasonable thing to try for a week. In moderate or severe deviation, strips usually feel like they do nothing — because, in terms of the structural problem, they are doing nothing.

Persistent, predominantly one-sided nasal obstruction deserves ENT evaluation rather than another box of strips. The most reliable way to find out what is actually narrowing the airway, and what will actually fix it, is an examination with a nasal endoscope by a specialist.
