If you have spent years sleeping with your mouth open, breathing through one nostril, or catching your reflection and noticing your nose sits slightly off centre, there is a reasonable chance a Nasal Septum Deviation Rhinoplasty is behind it. It is one of the most common structural problems in the human face — and one of the most frequently misunderstood, because the same anatomical problem can present as a purely functional complaint, a purely cosmetic one, or both at once.
This guide explains what a deviated septum actually is, why it happens, which symptoms genuinely warrant surgical assessment, how the three different nasal operations differ from one another, what the surgery and recovery involve, and what to look for when choosing a surgeon. It is written to inform, not to replace an in-person examination.
What Is a Deviated Nasal Septum?
The nasal septum is the partition running down the middle of your nose, separating the left and right nasal cavities. The front third is a sheet of flexible cartilage; behind it, the partition becomes bone — the perpendicular plate of the ethmoid above and the vomer below. The whole structure is covered on both sides by a thin, blood-rich mucous membrane.
A perfectly centred septum is genuinely rare. Most people carry some degree of deviation and never notice it, because the nose has enough spare capacity to tolerate a modest bend. It becomes a clinical problem — a deviated nasal septum, often shortened to DNS — when the bend narrows one or both passages enough to restrict airflow, or when it forms part of a broader structural asymmetry that also pushes the external nose off centre.
Two things are worth separating early, because they determine which operation is appropriate. The first is how the septum sits inside the nose. The second is how the nose looks from the outside. They are related but not the same. A severe internal deviation can hide behind a nose that looks perfectly straight, while a visibly crooked nose almost always has a deviated septum underneath it, since the septum is the central support beam the rest of the nose is built around.
What Causes a Deviated Septum?
A deviated septum is either something you were born with, something that developed as your face grew, or the result of an injury. In practice, the three overlap more than most people expect.
- Developmental deviation. The septum can bend during foetal development or as the facial skeleton grows, without any injury at all. Compression during birth is also recognised as a cause.
- Nasal trauma. A blow to the nose — from sport, a fall, a road accident or an assault — can displace the septum immediately or destabilise it so it deviates over the following months.
- An untreated nasal fracture. A broken nose that is never assessed and set will heal in whatever position it landed in. This is one of the most common routes to a nose that is both blocked and visibly crooked.
- Growth asymmetry in adolescence. Septal cartilage and the bony frame around it do not always grow at the same rate. When cartilage outgrows its housing, it buckles.
- Gradual change with age. Cartilage loses support over decades, and a mild deviation that never caused trouble at twenty can become symptomatic at fifty.
- Previous nasal surgery. Under-correction, over-resection or scarring from earlier surgery can leave a residual or new deviation, which is why revision cases are handled differently from first-time ones.
Septoplasty, Rhinoplasty and Septorhinoplasty: What Is the Difference?
These three names are used interchangeably in everyday conversation and mean quite different things in an operating theatre. Understanding the distinction is the single most useful thing a patient can do before a consultation.
| Septoplasty | Rhinoplasty | Septorhinoplasty | |
| Primary goal | Restore nasal airflow | Change the shape and proportion of the nose | Restore airflow and correct shape in one operation |
| What is altered | Deviated septal cartilage and bone inside the nose | External nasal bones, cartilage and tip | Both the internal septum and the external framework |
| Effect on appearance | Usually none | Visible change by design | Visible change plus improved breathing |
| Typical anaesthesia | General, or local with sedation | General | General |
| Typical operating time | Around 45 to 90 minutes | Around 1.5 to 3 hours | Around 1.5 to 3 hours |
| Usually indicated for | Blocked nose behind a straight-looking nose | Cosmetic concern with a clear airway | A crooked or injured nose that is also blocked |
| Insurance treatment | Often accepted as medically indicated — confirm with your insurer | Generally treated as elective and not covered | Depends on the documented functional component — confirm with your insurer |
The search term nasal septum deviation rhinoplasty almost always describes the third column. When the septum is deviated badly enough to twist the external nose, straightening the septum alone tends to under-deliver: the deviated external framework continues to pull the corrected septum back off centre, and the nose still looks crooked afterwards. Addressing the septum and the external structure together is what produces a nose that both breathes and sits straight.
Who Is a Candidate for Nasal Septum Deviation Rhinoplasty?
Generally suitable
- Persistent nasal obstruction confirmed on examination to be structural rather than purely mucosal or allergic
- A visibly deviated, twisted or post-traumatic nose alongside breathing difficulty
- Completed facial growth — broadly from around sixteen in girls and seventeen to eighteen in boys, assessed individually rather than by birthday
- Good general health, with any chronic conditions well controlled
- Realistic expectations about what surgery can and cannot change
- A non-smoker, or someone willing to stop for the period advised before and after surgery
Reasons to wait, or to reconsider
- Ongoing facial growth in a younger adolescent, where operating early risks disturbing development
- Active nasal or sinus infection — surgery is deferred until it has cleared
- Bleeding disorders, or blood-thinning medication that cannot be safely paused
- Poorly controlled diabetes, hypertension or other conditions that impair healing
- Pregnancy
- Continued smoking, which measurably impairs healing of nasal tissue and grafts
- Expectations that no operation could meet, or signs of body dysmorphic disorder — in which case surgery is not the right treatment and referral for psychological support is
How the Surgery Is Performed
Septorhinoplasty is carried out under general anaesthesia as a day-care or overnight procedure, depending on the extent of the work and the patient’s general health. The surgeon works through one of two approaches.
| Approach | How it is done | Best suited to | Trade-offs |
| Closed (endonasal) | All incisions are made inside the nostrils | Mild to moderate deviation with modest external work | No external scar and swelling settles sooner, but surgical visibility is more limited |
| Open (external) | A small incision across the columella, the strip of skin between the nostrils, lifts the skin for direct exposure | Severe deviation, twisted noses, complex grafting and revision surgery | Precise graft placement and control, at the cost of a small columellar scar and a longer swelling phase |
Whichever approach is used, the operation combines several steps chosen for the individual nose.
- Correcting the septum. Deviated cartilage and bone are straightened, scored, repositioned or partly removed. A supporting L-shaped strut of cartilage along the bridge and the front edge of the septum is always preserved — removing too much is what causes a collapsed or saddled bridge later. In severe deviation, the cartilage may be removed, reshaped outside the nose and reinserted.
- Reducing the turbinates. The turbinate on the wider side often enlarges over years to compensate for the deviation. Reducing it at the same time prevents that compensation from becoming the next obstruction.
- Opening the internal nasal valve. This is the narrowest point of the airway. Spreader grafts — thin strips of cartilage placed alongside the septum — widen it and simultaneously straighten the bridge line. This is a large part of why a combined operation often breathes better than septoplasty alone in a twisted nose.
- Repositioning the nasal bones. Controlled osteotomies allow deviated nasal bones to be moved back towards the midline so the bridge sits straight.
- Grafting. Cartilage from the septum is the first choice. Where the septum is depleted — common in revision surgery — cartilage may be taken from the ear or, less often, a rib.
- Closing and supporting. Fine dissolvable sutures, soft internal splints to hold the septum in position, and an external splint or cast over the bridge. Heavy nasal packing is used far less than it once was.

Frequently Asked Questions
Is nasal septum deviation rhinoplasty the same as septoplasty?
No. Septoplasty corrects only the septum inside the nose and does not change the external appearance. Nasal septum deviation rhinoplasty, or septorhinoplasty, corrects the septum and reshapes the external nose in the same operation. Which one you need depends on whether your nose is only blocked, or blocked and visibly deviated.
Will correcting my deviated septum change how my nose looks?
A straightforward septoplasty is designed not to. If your nose is externally crooked and you want that corrected, it needs to be planned deliberately as a combined procedure — it does not happen as a side effect of septal surgery.
How long does it take to breathe normally after surgery?
Breathing usually feels worse before it feels better, because internal swelling and splints block the nose for the first week or so. Most people notice meaningful improvement between two and four weeks, with the airway continuing to settle over the following months.
Is the surgery painful?
The operation itself is done under general anaesthesia, so nothing is felt during it. Afterwards, most patients describe pressure, congestion and a dull ache rather than sharp pain, and it is generally well controlled with prescribed medication.
Will there be a visible scar?
A closed approach leaves no external scar at all. An open approach leaves a small incision across the columella, the strip of skin between the nostrils, which typically fades to become difficult to see once healed.
Can a deviated septum be corrected without surgery?
The deviation itself is a structural problem and cannot be straightened by medication. Sprays, antihistamines, allergy treatment and nasal strips can relieve the mucosal component of congestion, and for mild cases that may be enough — but they do not move cartilage or bone.
At what age can this surgery be done?
Surgery is generally deferred until facial growth is complete, broadly from around sixteen in girls and seventeen to eighteen in boys, assessed individually. Significant obstruction in a younger child is managed on its own merits by a specialist rather than by a fixed rule.
