I am a surgeon, so you might reasonably expect me to say no and offer you an operation. The real answer is more useful than that, and it comes in two parts.
Can you straighten a deviated septum without surgery? No. Not with exercises, not with a clip, not with manipulation, not with anything sold online. The septum is cartilage at the front and bone behind. Once it has set in a bent position, nothing short of cutting and repositioning it changes its shape. Anyone telling you otherwise is selling something.
Do you need to straighten it in order to breathe better? Often, no. And that is the part almost nobody explains.
Why the second answer matters more
Your nasal airway is narrowed by two different things at once: the fixed structure, and the soft tissue lining wrapped around it. The lining swells and shrinks constantly, in response to allergy, temperature, position, alcohol, hormones and time of day.
Most people with a deviated septum are not blocked by the cartilage alone. They are blocked by the cartilage plus swelling. Take the swelling away and a surprising number of people cross back over the threshold into comfortable breathing, with the bend still exactly where it was.
That is the entire logic of medical treatment. It is not trying to fix the septum. It is trying to give you back the millimetres the swelling took, so the bend stops mattering.
Whether that works depends on how much of your narrowing is structural. If the septum is severely deviated and touching the side wall, no amount of shrinking the lining will save you. If it is moderate, medical treatment frequently succeeds.
The problems that travel alongside the blockage
Some degree of deviation is extremely common, and most of it never causes trouble. When it does, a blocked nose is rarely the only complaint. Three other issues tend to arrive with it, and each one changes what treatment makes sense.
Sinus infections. Each sinus drains into the nasal passages through an opening a few millimetres across. A deviation that crowds those openings, particularly a spur high up, makes it harder for that sinus to clear itself. It can be part of why some people get repeated infections on one side and never on the other. If chronic sinusitis is running alongside the deviation, treating the sinus inflammation in its own right, with a steroid spray, saline and occasionally a course of antibiotics, often does more for you than anything aimed at the septum. Polyps belong in the same conversation and are worth ruling out, since they block the nose far more effectively than any bend does.
Facial pain. Where a septal spur presses against the turbinate on the side wall, the contact itself can produce a dull ache behind the eye or across the cheek. It gets mistaken for sinus pain constantly. Shrinking the lining with a spray sometimes separates the two surfaces and settles it, which makes it a useful test as well as a treatment.
Ear pressure. The eustachian tube opens at the back of the nose. Congestion at that end gives ear fullness, popping and muffled hearing, worst on aeroplanes. Reduce the nasal congestion and the ear symptoms usually follow it down.
What helps a deviated septum without surgery?
A steroid nasal spray, used correctly, for long enough. Mometasone or fluticasone, once daily, for at least eight weeks before you judge it.
Technique is where nearly everyone fails. Head tilted slightly forward. Spray into the left nostril with your right hand and vice versa, aimed outwards towards the cheekbone on the same side, never straight up the middle at the septum. Do not sniff hard afterwards, or you will simply swallow it. A gentle in-breath is enough.
Spray technique matters more than most people realise: changing nothing but the technique often makes a clear difference within weeks. If you take one thing from this article, take that.
People also worry about the word steroid, so it is worth saying plainly: at standard doses, very little of a modern steroid nasal spray is absorbed into the body, and these sprays are considered safe for long-term daily use. The commonest side effects are minor nosebleeds and crusting, and when they happen they usually mean the spray is being aimed at the septum rather than away from it. Fix the aim and they generally settle.
Large-volume saline irrigation. A proper rinse, not a small spray. Small saline sprays moisten the lining, which is pleasant enough, but they do not deliver the volume needed to wash mucus and allergens out. A rinse does. NeilMed Sinus Rinse from any chemist, morning and evening. It clears mucus and allergens and improves the local environment, and the Cochrane evidence supports it. Unglamorous, cheap, and genuinely effective.
Treating the allergy, if there is one. If your symptoms track pollen, pets or bedding, the allergy is doing real work and treating it properly changes the picture. Antihistamines help the sneezing and running more than the blockage. The spray helps the blockage. Both, plus allergen avoidance where practical, is the combination.
An anticholinergic spray, if the real complaint is running rather than blockage. Ipratropium bromide, available on prescription, reduces watery nasal discharge, including the running set off by eating or cold air. It does nothing for the blockage and nothing for the septum, so it is the right spray only when a constantly dripping nose is the symptom that bothers you most. It can be used alongside a steroid spray when both problems exist.
Stopping decongestant sprays. This is the most important single intervention for a subgroup of people, and it is counter-intuitive because it makes things worse before better.
Xylometazoline and oxymetazoline, sold as Otrivine and Sudafed, work by constricting the blood vessels in the nasal lining, which shrinks it within minutes. That is why they work so beautifully for a few days. Used beyond about a week they cause rebound swelling: the nose closes harder as each dose wears off, so you use more, so it swells more. It is a recognised condition called rhinitis medicamentosa, and it is why the packet carries a maximum-duration warning. People who have used a decongestant bottle a week for years often believe the nose itself has deteriorated, when it is the spray doing the damage. It has, and the spray did it. Coming off takes an unpleasant fortnight and then almost everyone is better than before.
Nasal strips or internal dilators, if your narrowing is at the valve. Test it first: pull your cheek gently outwards beside your nose and breathe in. If that is an obvious improvement, the narrowest point is the nasal valve rather than the septum, and a strip or dilator may genuinely help. If it does nothing, strips will not help you either.
Sleeping propped up. Raise the head end of the bed by ten to fifteen centimetres, rather than stacking pillows. It reduces the overnight congestion that makes a deviated septum feel so much worse in bed.
Sorting out the air at home. Dry, overheated, dusty air makes a marginal nose feel far worse than it is. A humidifier through the winter, a filter in the bedroom if dust is your trigger, and keeping pets off the bed are small measures that give you back a little margin. None of it changes the shape of anything. It stops you losing ground, and that is worth more than it sounds.
What does not work for a deviated septum?
Nose clips, shapers and "septum correctors". These are sold on the premise that sustained pressure reshapes cartilage. It does not work on an adult nose, and the septum is internal in any case, so a device clamped to the outside is not touching it. At best a waste of money. At worst they cause pressure damage to the skin and lining.
Fillers and non-surgical nose jobs. Injectable filler can camouflage a crooked bridge from the outside. It does nothing to the airway and it cannot reach the septum. If your nose looks crooked as well as feeling blocked, the two are related but they are not one problem, and no injectable procedure solves both. More on that in my piece on non-surgical rhinoplasty, and on the crooked nose itself.
Nose exercises and "septum realignment" routines. There is no muscle attached to the septum to exercise. Videos demonstrating this are demonstrating nothing.
Manual manipulation, including by a chiropractor or osteopath. There is a narrow genuine exception: a fresh nasal fracture can be manipulated back into position, but only within roughly the first two weeks after the injury, under proper assessment, by someone qualified to do it. That is a specific acute treatment for a broken nose, not something that applies to a deviation you have had for fifteen years. Manipulating an established deviation does not reposition it, and forceful attempts risk a septal haematoma, which is a genuine emergency.
Breathing retraining alone. Techniques such as Buteyko have their advocates for other purposes. They do not widen a structurally narrow airway.
Steam, menthol and vapour rubs. They alter the sensation of airflow by stimulating cold receptors. They feel like they are opening your nose. They are not changing airflow at all. Harmless, briefly pleasant, not a treatment.
The honest test of whether you need surgery
Do this properly and you will have your answer in about two months:
- Stop any decongestant spray entirely, and allow a fortnight for the rebound to settle
- Start large-volume saline rinses, morning and evening
- Start a steroid spray, once daily, with the technique above
- If allergy is likely, get tested and treat it alongside
- Give it eight weeks before making any judgement
If you are meaningfully better, you have your answer and you do not need me. Keep going.
If you have done all of that, correctly, for eight full weeks, and you are still blocked, then the remaining obstruction is structural. That is the point at which a surgical assessment is worth having. Note that this is not the same as a commitment to surgery: it is the point at which someone should look inside with a camera and tell you what is actually there.
A patient who has tried five different sprays for three weeks each is in a completely different position from one who has used a single spray correctly for eight weeks. The first often gets better with proper medical management. The second usually does not.
How is a deviated septum actually diagnosed?
Everything above can be started in primary care and it should be. Your GP can prescribe the spray, check for allergies, and tell you whether your technique is right. If eight weeks of correct treatment has not made a difference, that is the point to ask for a referral to an ear, nose and throat surgeon. See a doctor sooner rather than later if you have nosebleeds, one-sided nasal blockage that has changed recently, facial pain with fever, or any loss of smell.
What an ENT appointment adds is sight. At a consultation I take the history, look at the outside of the nose, then pass a thin endoscope along the floor of each nostril. It takes about a minute, and it is the only way in clinic to see where the nasal septum actually sits, whether the turbinates are enlarged, whether the nasal valve collapses inwards when you breathe in, and whether anything is hiding behind all of it.
The diagnosis matters because the treatment options diverge from that point. Turbinate hypertrophy, nasal valve collapse and a deviated septum feel identical from the inside, and none of them is managed the same way. Plenty of patients arrive certain the septum is the problem and leave knowing most of it is the valve. That is not a wasted appointment. It is the difference between an operation that helps and one that does not.
When surgery is genuinely the only option
If the deviation is severe, if the septum is in contact with the side wall of the nose, or if eight weeks of correct medical treatment has failed, then septoplasty is what remains.
Worth knowing before you decide: the NAIROS trial, run across seventeen NHS hospitals and published in 2024, found a large benefit for people with moderate to severe symptoms and very little for those with mild ones. If your symptoms are mild, surgery is a marginal intervention and medical treatment is the better bet. If they are moderate or severe and medical treatment has properly failed, the evidence for meaningful improvement is strong.
If the outside of your nose is bent as well as the septum, straightening only the inside tends to under-deliver, and a septorhinoplasty addresses both together. I would rather explain that distinction beforehand than have you discover it afterwards.
The full detail on the operation, the evidence and the costs is in my main guide: deviated septum, symptoms, surgery and recovery. If you are not yet sure the septum is your problem at all, start with how to tell if you have a deviated septum.
Frequently asked questions
Can a deviated septum fix itself?
No. Cartilage and bone do not return to a straight position on their own once set. Symptoms can improve if the swelling component settles, which is why some people feel better for periods.
Can you push a deviated septum back into place?
Not an established one. A fresh nasal fracture can sometimes be manipulated within about two weeks of injury by a qualified clinician. Attempting it on a long-standing deviation does not work and risks a septal haematoma.
Do nose clips, septum correctors or nose exercises work?
No. The septum is internal, so a device clamped to the outside is not touching it, adult cartilage does not remodel under sustained pressure, and there is no muscle attached to the septum to exercise. At best they waste money; at worst clips cause pressure damage to the skin.
Which nasal spray is best for a deviated septum?
A steroid spray such as mometasone or fluticasone, because it treats the swelling around the deviation, which is the part that can actually change. Saline rinses support it, decongestant sprays should never run beyond a few days, and an anticholinergic spray helps only a runny nose. None of them alters the septum itself.
Are steroid nasal sprays safe to use long term?
At standard doses, yes. Very little of a modern steroid spray is absorbed into the body, and daily long-term use is accepted practice. Minor nosebleeds or crusting usually mean the technique needs correcting, not that the spray must stop.
How long should I try sprays before giving up on them?
Eight weeks of daily use with correct technique. Anything less is not a fair test.
Do decongestant tablets work better than the nasal sprays?
Oral decongestants such as pseudoephedrine open the nose fairly quickly and give short-term relief without the rebound problem that the sprays cause, but they are not a long-term answer and they do not suit everyone, particularly with high blood pressure or heart problems. Ask a pharmacist before you start.
Can a deviated septum cause sinus infections, facial pain or ear pressure?
All three, indirectly. A bend that narrows a drainage pathway makes it harder for that sinus to clear, which is why repeated infections on one side are worth looking into. A spur touching the side wall can produce a contact pain that feels exactly like sinus pain, and congestion around the eustachian tube causes ear fullness and popping. Chronic sinusitis still needs treating as a condition of its own, not as a side effect of the septum.
If medical treatment works, do I still need the operation eventually?
Not necessarily. Plenty of people manage indefinitely on a spray and saline. Surgery is for when that stops being enough.
What are my options if eight weeks of medication fails?
The honest list is short. Carry on as you are and accept the blockage you have, or have the septum straightened. Septoplasty is done entirely through the inside of the nose, as a day case, so there is nothing visible afterwards. My fees are on my pricing page.
If you have done the eight weeks properly and you are still blocked, that is exactly the point at which an examination is worth having. You can book a consultation, and if I think medical treatment has not yet been given a fair run, I will tell you that rather than book you an operation.
