Dorsal Hump: Causes, Treatment and When a Nose Bump Needs Checking

A dorsal hump is a raised area along the bridge of the nose, made of bone and cartilage, that gives the profile a convex curve rather than a straight line. It is extremely common, entirely benign, and for most people it is simply the nose they were born with — a convex profile of this kind is often described as a Roman nose.

But “a bump on my nose” and “a dorsal hump” are not always the same thing, and the difference matters more than anything else on this page.

A dorsal hump has been there your whole life, sits in the midline, and feels like part of the nose. A lump that has appeared — particularly one on one side, one that has grown, or one that bleeds or crusts — is a different question entirely, and it belongs with a GP rather than a cosmetic surgeon.

The next two sections cover that. Everything after them is about the dorsal hump proper.

Bump on Nose Bridge: Lifelong Hump or New Lump?

A dorsal hump:

• Has been present as long as you can remember, or since your teens
• Sits in the midline, running along the bridge
• Is smooth and continuous with the rest of the nose
• Has not changed in years
• Is skin-coloured and looks like normal skin
• Follows an old injury, if it appeared at all

A new lump is different:

• You noticed it recently, or it has changed
• It is often to one side rather than along the midline
• It feels like a discrete lump rather than part of the bridge
• The skin over it may look different — pearly, red, scaly, ulcerated
• It may bleed, crust or fail to heal

Inflammation does not create a dorsal hump. Neither do allergies, sinus problems or nasal polyps — polyps sit inside the nose and cannot produce a lump you can see or feel from outside. If something has appeared on the outside of your nose, that is a skin or bone problem and needs looking at as such.

Lump on Nose: When to See a GP

See your GP about a lump on your nose if:

• It has appeared or changed in the last months or year
• It is growing, however slowly
• It bleeds, crusts or scabs, particularly repeatedly
• It has not healed after several weeks
• The skin over it looks different — pearly, shiny, red, scaly, or with small visible vessels
• There is an ulcer or sore that keeps coming back
• It is painful, hot, or the surrounding skin is red

The nose is one of the commonest sites for basal cell carcinoma^[1], the most frequent form of skin cancer. Basal cell carcinomas grow slowly, are highly treatable when caught early, and are frequently mistaken for a spot, a scar or a bump that will not go away. Squamous cell carcinoma also occurs here.

Other causes of a genuinely new lump include an osteoma (a benign bony growth), a cyst, a dermoid, a callus from an old fracture healing, an infected hair follicle, or simple swelling after injury.

Most turn out to be nothing. But the assessment is a GP examination, potentially a biopsy — not a cosmetic consultation, and not something to be treated with filler.

If you have a new lump, please see your GP first. We would rather say that than book you a consultation.

What Is a Dorsal Hump?

The bridge of the nose has two components. The upper third is nasal bone. The middle third is upper lateral cartilage. A dorsal hump typically sits across the junction between them, which is why it is described as osseocartilaginous — part bone, part cartilage.

That composition explains a lot. It is why a hump cannot simply be filed down in one motion; the bone and cartilage behave differently and need different handling. And it is why removing a hump opens up the roof of the nose, which then has to be closed again — covered below.

A hump is usually invisible from the front and obvious in profile. Some are barely perceptible; some are prominent. Neither is a medical problem.

What causes a dorsal hump?

• Genetics. By far the commonest cause. Dorsal humps run in families and are more prevalent in some populations than others — Mediterranean, Middle Eastern and South Asian ancestry particularly. This is normal anatomical variation. See nose shapes and ethnic rhinoplasty.
• Puberty. Often not visible in childhood and appearing as the nose grows through the teens. This is normal development, not something going wrong.
• Previous injury. A healed nasal fracture can leave a bony callus or a step in the bridge, and this is the one situation where a hump genuinely appears in adulthood. It follows a specific injury rather than emerging from nowhere. See broken nose.
• Ageing. As the tip loses support and drops slightly over decades, an existing hump can look more prominent without having changed at all.

Is a dorsal hump attractive?

There is no medical answer, and preferences shift. The straight or slightly concave profile that dominated cosmetic surgery in the 1990s now reads as dated and over-operated, and a meaningful proportion of revision rhinoplasty exists to rebuild noses that were reduced too far.

A convex profile is a normal, common and widely admired feature. It is also entirely reasonable to want it changed. What is not reasonable is being told it is a defect.

Does a Dorsal Hump Affect Breathing?

No — and the opposite is closer to the truth.

A dorsal hump is external contour. The airway sits beneath it and is unaffected by the shape of the bridge above. Blocked breathing is caused by internal structures: a deviated septum, enlarged turbinates, nasal valve collapse or nasal polyps.

Where the two are found together — and they often are, particularly after injury — the septum is the cause and the hump is coincidental.

You will find claims that removing a dorsal hump improves breathing or treats sleep apnoea. It does not. Nasal surgery has a genuine role in sleep-disordered breathing, but that role is relieving internal obstruction and improving CPAP tolerance, not reducing the profile. In a 2015 systematic review and meta-analysis in Sleep ↗ of 18 studies, isolated nasal surgery lowered therapeutic CPAP pressure from a mean of 11.6 to 9.5 cmH2O^[2]. See snoring and sleep apnoea.

Open Roof Deformity: Why the Roof Is Rebuilt After Hump Removal

This is the most important technical point on the page, and it is where hump reduction goes wrong.

The middle of the nose is built like a roof — two upper lateral cartilages meeting the septum at the ridge. Removing a hump takes the top off that roof, leaving what surgeons call an open roof deformity: a flat, wide gap where the peak used to be.

If that roof is not closed and supported, two things follow, usually months or years later:

• An inverted-V deformity — a visible shadow where the nasal bones end and the unsupported cartilage begins
• Middle vault collapse and internal valve narrowing, causing the breathing problems the hump never caused in the first place

In a 2026 systematic review and meta-analysis in Aesthetic Plastic Surgery ↗ of nine studies (1,364 patients), contour irregularity accounted for 41% of recorded late complications after hump surgery, and nasal valve collapse was also reported^[3].

Proper hump reduction therefore involves closing the roof — narrowing the bones with controlled fractures (osteotomies) and placing spreader grafts to support and reconstruct the middle vault.

Preservation rhinoplasty approaches this differently, lowering the whole dorsum rather than removing the top of it, so the roof is never opened. See preservation rhinoplasty and ultrasonic rhinoplasty, which allows more precise bone reshaping. A 2025 meta-analysis of ten studies (1,339 patients) in the Journal of Plastic, Reconstructive & Aesthetic Surgery ↗ found preservation gave fewer dorsal irregularities than reduction but a higher rate of residual or recurrent hump, with no significant difference in functional outcomes or revision surgery^[4].

If you take one thing from this page into a consultation, ask how the surgeon plans to manage the open roof. The answer tells you a great deal.

Dorsal Hump Removal: Filler or Surgery?

Non-surgical rhinoplasty

Dermal filler placed above and below the hump fills the dips either side, so the profile reads as a straighter line. It takes about 15 minutes, requires no downtime, and lasts 12 to 18 months.

The trade-off is worth understanding: filler cannot remove anything. It camouflages the hump by making the surrounding nose slightly larger. For a small hump on a nose that is not already prominent, that is often an excellent result. For a large hump, or where the aim is a smaller nose, it is the wrong tool.

There is also a small but real risk of vascular occlusion, so it should be performed by an experienced injector with hyaluronidase available. A 2024 systematic review in Aesthetic Plastic Surgery ↗ covering 9,657 patients, 97% of them treated with hyaluronic acid, reported 99% satisfaction and serious vascular complications in 0.27%^[5], and a separate review found that early hyaluronidase use was critical in managing vascular occlusion^[6]. See non-surgical rhinoplasty.

Rhinoplasty

Surgical reduction removes the bony and cartilaginous excess, closes the open roof with osteotomies and spreader grafts, and refines the tip where needed so the profile stays balanced. Performed via an open or closed approach.

A point rarely made: reducing a hump without addressing the tip often produces a nose that looks longer or droopier. The hump was providing visual balance against the tip, and taking it away changes that relationship. Good hump reduction is rarely hump reduction alone.

What does not work

No exercise, massage, taping, clip or tool reduces a dorsal hump. It is bone and cartilage. Makeup contouring works visually and carries no risk.

Dorsal Hump Surgery Recovery

A splint is worn for about a week, bruising settles over two to three weeks, and most people return to desk work within one to two weeks. Exercise resumes at four weeks and contact sport at six.

The profile looks straight almost immediately once the splint is off — hump reduction gives one of the most visible early changes in rhinoplasty. Final refinement of the tip and middle third takes 12 to 18 months, longer in thick skin. See rhinoplasty recovery.

Can a dorsal hump come back?

Not in the sense of regrowing. What can happen is a small callus forming at the reduction site during healing, producing a minor irregularity, or the appearance of a residual hump where the reduction was conservative. Both are recognised reasons for minor revision, and neither is the bone growing back.

Dorsal Hump Removal Cost

Cost depends on whether the change is achieved with filler or surgery, and on the complexity of the surgical plan — whether osteotomies, spreader grafts and tip work are required alongside the reduction. Your exact cost is confirmed in writing after in-person consultation.

Finance is available through Chrysalis Finance, subject to status — see our finance options. Rhinoplasty performed for appearance alone is not available on the NHS.

Frequently Asked Questions: Dorsal Hump

Rhinoplasty Consultation at Centre for Surgery

Assessment starts with establishing which question you are actually asking — whether this is a lifelong profile you would like changed, or something that has appeared and needs identifying. Those go in different directions, and we will tell you plainly if what you have needs a GP rather than a surgeon.

For a genuine dorsal hump, assessment covers the bone and cartilage components, skin thickness, tip support and the balance of the whole profile, alongside the nasal airway, which our ENT surgeon and rhinologist examines at the same time.

We will also be explicit about how the open roof will be managed, because that is what determines whether the result holds up in five years.

All surgery is performed by GMC-registered surgeons at our own day-surgery facility at 95–97 Baker Street, Marylebone. We are regulated by the Care Quality Commission and rated Good overall. We recommend a two-week cooling-off period before any surgery is booked.
