Causes of Nasal Deformity: Why Noses Become Crooked, Humped or Droopy

Jul 5, 2019

Key takeaways

  • Nasal deformities are either congenital/genetic (inherited shape, developmental problems) or acquired (trauma, hormonal growth changes, disease, drug use, previous surgery).

  • Common signs are a crooked nose, a dorsal hump, a drooping tip, uneven nostrils and blocked breathing.

  • Many deformities cause both aesthetic and functional problems, so treatment often combines cosmetic reshaping with septum and airway repair.

  • Rhinoplasty or septorhinoplasty corrects most deformities in a single operation.

What is a nasal deformity?

A nasal deformity is any deviation of the nose from its normal shape or structure. It may be present from birth, develop during growth, or be caused later in life by an injury, an illness or a previous operation. Because the nose is made of bone, cartilage and skin that all grow and heal differently, a small problem in one part often distorts the others. A deformity can be purely cosmetic, purely functional (breathing) or, most often, both.

Genetic and congenital causes

The shape of your nose is largely inherited. Families share dorsal humps, wide tips, long noses and deviated septums the same way they share eye colour. Some congenital problems are more specific:

  • Deviated septum from birth. Pressure during delivery or asymmetric growth of the septal cartilage can bend the septum, producing a crooked nose and a blocked airway.

  • Cleft lip and palate. The nose on the cleft side is typically flattened and asymmetric and needs specialised rhinoplasty.

  • Ethnic and familial features. Thick skin, weak tip cartilages, a low bridge or a wide base are not diseases but frequently motivate rhinoplasty.

Acquired causes

1. Growth and hormonal changes

The nose grows fastest during puberty, and this is when most humps, long noses and septal deviations appear. Uneven growth between the cartilage and bone, or between the two sides of the septum, produces a bend or a bump that becomes permanent by the end of adolescence. This is why rhinoplasty is generally delayed until growth is complete, around 16–17 in girls and 17–18 in boys. Rare hormonal disorders such as acromegaly enlarge the nose in adulthood.

2. Trauma and injury

A blow to the nose is the most common acquired cause. Sports injuries, falls, traffic accidents and fights fracture the nasal bones or dislocate the septum. If the fracture is not reset within about two weeks it heals in the wrong position, leaving a crooked nose, a hump at the fracture line or a collapsed bridge (saddle nose). Childhood injuries are especially important because they can disturb subsequent growth and the deformity appears years later.

3. Disease

Several conditions damage nasal structure. Skin cancers near the nose (basal cell and squamous cell carcinoma) and their removal can leave visible defects. Inflammatory diseases such as sarcoidosis, granulomatosis with polyangiitis, relapsing polychondritis and untreated infections can destroy septal cartilage and cause the bridge to collapse. Large nasal polyps widen the nose from inside.

4. Drug use and medication

Long-term intranasal cocaine use is a well-known cause of septal perforation and saddle nose. Overuse of decongestant nasal sprays damages the lining and worsens obstruction, and prolonged intranasal steroid misuse can thin the septum. These deformities are difficult to repair and usually require cartilage grafts from the rib or ear.

5. Previous surgery

Over-resection in an earlier rhinoplasty is one of the most common reasons patients see Prof. Dr. Suleyman Tas. Removing too much cartilage weakens the nose, causing a pinched tip, an inverted-V deformity, nasal valve collapse or a saddle nose years later. These are corrected with structural revision rhinoplasty.

Symptoms of a nasal deformity

  • A crooked or twisted nose when viewed from the front

  • A hump or bump on the bridge

  • A drooping or bulbous tip

  • Uneven, flared or collapsed nostrils

  • A collapsed bridge (saddle nose)

  • Blocked breathing, mouth breathing, snoring or poor sleep

  • Recurrent sinus infections or nosebleeds

Aesthetic signs are visible in the mirror; functional signs are felt every day and night. Both deserve evaluation.

How nasal deformities are treated

Treatment begins with a physical examination, an endoscopic look inside the nose and, when needed, a CT scan. Depending on the findings the plan may include:

  • Septoplasty to straighten the internal septum when breathing is the only problem.

  • Rhinoplasty to reshape the bones and cartilage: hump removal, tip refinement, narrowing of the bones.

  • Septorhinoplasty combining both, the most common solution for a crooked nose.

  • Structural grafting with septal, ear or rib cartilage to rebuild collapsed or over-resected noses.

  • Ultrasonic (piezo) bone shaping, used at Prof. Dr. Suleyman Tas Clinic to correct crooked bones with less bruising and greater precision.

Prof. Dr. Suleyman Tas has performed thousands of primary and revision operations over more than 20 years, with particular expertise in traumatic and post-surgical deformities. Results are shown in the before and after gallery.

Frequently asked questions

Can a crooked nose be fixed without surgery?

Minor asymmetries can be camouflaged with filler, but a truly crooked nose or a deviated septum can only be corrected surgically.

Should a broken nose be treated immediately?

Yes. A fracture reset within 7–14 days usually heals straight. After that, the bones set and a formal rhinoplasty is required.

At what age can a childhood nasal deformity be corrected?

Cosmetic correction waits until facial growth is complete (about 16–18). Severe breathing problems can be treated earlier with conservative surgery.

Does a nasal deformity always affect breathing?

No, but a crooked nose very often comes with a deviated septum, which is why both are checked at consultation.

Is a saddle nose repairable?

Yes. Rib or ear cartilage grafts rebuild the bridge; read our post on saddle nose repair.
