One Nostril Bigger Than the OtherWhy nostrils are uneven and when the difference can be improved

Medically reviewed: Last reviewed by Mr Reza Nassab, FRCS Plast —

It is very common for one nostril to be slightly larger or shaped differently from the other, and in most people this is a normal variation. More noticeable differences are often caused by a deviated septum pushing into one nostril, uneven tip cartilages or a difference in the nostril base. If the asymmetry bothers you or affects breathing, rhinoplasty, septal surgery or alar base adjustment can improve balance, although perfect symmetry is not realistic.

Why nostrils are rarely identical

The two sides of the face develop separately and are never exact mirror images. Small differences in the cartilages that form the nostril rims, in the angle of the columella (the strip between the nostrils) and in where each nostril meets the cheek all show up when you look at the nose from below. Many people only notice their nostrils in close-up photographs or when looking in a magnifying mirror, and others rarely notice the difference at all.

Common causes of a larger nostril

  • Deviated septum: if the front edge of the septum bends into one nostril, that side looks smaller and the opposite side larger.
  • Tip cartilage asymmetry: the lower lateral cartilages may differ in size, shape or strength between sides.
  • Nostril base differences: one nostril may sit wider or flare more where it joins the cheek.
  • Previous injury: a knock can shift the septum or cartilages, sometimes years before the difference is noticed.
  • Cleft lip: people born with a cleft lip often have nostril asymmetry, which is usually managed by specialist cleft teams.
  • Previous surgery: earlier nasal surgery or scarring can alter the shape of one side.

Does it affect breathing?

Asymmetry alone does not necessarily affect breathing. However, when a deviated septum is responsible, the narrower side may feel blocked, particularly at night or during exercise. Weakness of a nostril wall can also cause it to collapse inwards on breathing in. If one side of your nose feels persistently blocked, see your GP, who may suggest a trial of nasal spray or refer you to an ENT specialist. Persistent one-sided blockage with bleeding, crusting or a foul-smelling discharge should be assessed promptly.

Non-surgical approaches

Mild asymmetry usually needs no treatment. Small amounts of dermal filler can occasionally be used to disguise minor differences at the nostril rim or columella, but results are temporary, the amount of correction is small, and filler in this area carries a risk of blood vessel blockage. It cannot correct a deviated septum. Nasal dilators or strips may help breathing in some people but do not change appearance.

Surgical options

Treatment is tailored to the cause. Where the septum is bent into one nostril, repositioning its front edge can make the nostrils more even and often improves airflow. Reshaping or supporting the tip cartilages can balance the nostril rims. Where one nostril base is wider, a small, asymmetric alar base reduction can narrow that side, leaving a fine scar in the groove beside the nostril. These techniques are often combined within rhinoplasty, but a smaller procedure may be enough in some cases. Mr Nassab will examine the nose from every angle, including from below, to identify which structures are responsible.

How the nostrils are assessed

At consultation, Mr Nassab will look at the nose from the front, side and below, and examine the inside with a light to see the position of the septum and the health of the lining. He will check whether either nostril wall collapses when you breathe in, and look at how the nostrils move when you smile. Standardised photographs, including a view from beneath the nose, help to show the difference clearly and are used to plan and later compare results. Any history of injury, allergies, previous surgery and nasal spray use is also relevant.

Realistic expectations

The aim is better balance, not perfect symmetry. Nostrils are small structures, and even minor healing differences can show. Some asymmetry commonly remains after surgery, and the final shape takes up to a year or more to settle as swelling resolves. Further adjustment is occasionally needed. Understanding this before surgery helps avoid disappointment.

Cost

Rhinoplasty costs from £8,950. Smaller procedures, such as isolated nostril adjustment, are quoted at consultation. The £150 consultation fee is separate. Cosmetic surgery is for adults aged 18 and over.

Frequently Asked Questions

Is it normal to have one nostril bigger?

Yes. Some asymmetry is present in most people and is not a cause for concern on its own.

Can a deviated septum make one nostril look bigger?

Yes. If the front of the septum leans into one nostril, it narrows that side and makes the other look larger.

Can uneven nostrils be fixed without rhinoplasty?

Sometimes. A small nostril base adjustment or septal procedure may be enough, depending on the cause.

Will surgery make my nostrils perfectly even?

Perfect symmetry is not achievable, but surgery can often make the difference much less noticeable.
