In short. The narrow corrections volume can make, its genuine advantage of being dissolvable, and its vascular risk stated plainly, including the eye.

Key points

  • If the result is wrong, or too much was placed, an enzyme can usually break the material down.
  • That option does not exist for an operation, and it is a real reason some patients begin with an injection.
  • It is not absolute: dissolving may not remove everything, and the tissue may not return exactly to its previous state.

An injectable changes one thing, in one direction: it adds volume. That sounds like a limitation, and it is, but it also produces genuine corrections an operation is not designed for, and it carries one advantage no operation has.

What it changes

A shallow dip along the bridge can be filled so the profile reads more evenly. A small asymmetry can be balanced, sometimes in a way that an operation would find disproportionately difficult. The angle between the nose and the upper lip can be softened, which changes how the nose sits in the face without changing the nose itself. A bridge that looks low relative to a strong forehead or chin can be built up so the proportions read differently. All of those are changes to how the nose relates to the rest of the face, made by adding material rather than by altering structure.

It can be dissolved

If the result is wrong, or too much was placed, an enzyme can usually break the material down. That option does not exist for an operation, and it is a real reason some patients begin with an injection. It is not absolute: dissolving may not remove everything, and the tissue may not return exactly to its previous state.

The risk that belongs to this area

The nose is a high-risk area for injection, and it is worth stating without hedging. Material placed there can enter the blood supply that feeds the skin, and if it does, the skin can be injured or lost. In the rarest cases material can reach the circulation of the eye, and visual loss has been reported. This is uncommon and serious. It is why the injector should be experienced in recognising it, why the means to dissolve the material should be available, and why a patient should be told what to look for afterwards rather than reassured that it does not happen.

What it does not do

It does not reduce anything, so a hump, a wide bridge or a heavy tip is not corrected by it. It does not change structure, so a nose that drops when you smile will go on dropping. It does not improve a structural obstruction of breathing. It does not last, and its long-term behaviour when volume is added to the same nose repeatedly over years is not well described. And it cannot promise that the result will look natural in a thin nose, where material can be visible through the skin.

What to ask before nasal filler

  • What will be done if material enters the blood supply of the skin, and whether an enzyme is available immediately.
  • What to look for in the first hours after treatment, and who to contact if it appears.
  • Whether the problem being treated is one of volume, and what the structural alternative would be.

An injectable is a reasonable option for a defined volume problem in a nose whose structure is otherwise satisfactory, and a poor one for a nose that needs to be smaller. The filler pages cover the materials and their behaviour, and the filler complication pages cover what happens when something goes wrong.

Frequently asked questions

What kinds of nasal problem suit an injectable?

Volume problems in a defined place: a shallow dip on the bridge, a small asymmetry, an angle between the nose and the lip that reads too sharp, or a bridge that looks low relative to the rest of the face. Each of those is corrected by adding a small amount of material rather than by changing structure, and each is visible within days once the swelling settles.

How serious is the vascular risk really?

It is uncommon and it is serious, and both halves of that sentence matter. Material placed in the nose can enter the blood supply of the skin, which can injure or destroy the skin over the nose; in the rarest cases material can reach the circulation of the eye and cause visual loss. It is why the nose is treated as a high-risk area and why the ability to dissolve the material matters.

Is dissolving completely reliable?

Not completely. An enzyme dissolves material that is dissolvable, and it is most effective when used early and when the material is one that responds to it. After repeated treatment, or with material that is not purely dissolvable, some may remain. Dissolving also does not guarantee that the tissue returns exactly to its previous shape, because it has been stretched by what was placed in it.

Risks & Limitations

  • Nasal filler carries an uncommon and serious risk. Material placed in the nose can enter the blood supply of the skin and injure it, and in the rarest cases reach the circulation of the eye. The nose is treated as a high-risk area for this reason.
  • Injecting can only add volume. It cannot make a nose smaller, remove a hump, narrow a bridge or reduce a tip, and adding volume to a nose that is already large makes it larger.
  • Filler is absorbed over months, so maintaining the change means repeating the treatment. The long-term behaviour of volume added to the same nose repeatedly over years is not well described in the literature.
  • Dissolving material with an enzyme usually works, particularly when used early, but it does not always remove everything and does not guarantee that the tissue returns to its previous shape.
  • Rhinoplasty is an operation on the face and carries the risks of one: bleeding that may require a return to theatre, infection, poor healing, asymmetry and altered sensation.
  • Breathing may change after an operation and is not guaranteed to improve. An operation performed only for appearance can occasionally worsen it.
  • Revision after rhinoplasty is a real possibility rather than a rare one. It is a further operation on tissue that has already been operated on, longer and with added risk, and it cannot restore the original nose.
  • Neither option is guaranteed. How a nose settles, how long an injectable lasts and how the skin responds vary between individuals, and no result can be promised in advance.

When to Seek Care

  • Pain, blanching or dusky discolouration of the skin after nasal filler, or any change in vision — this needs immediate attention.
  • Increasing redness, swelling, warmth or discharge after either treatment, particularly with a fever.
  • Bleeding that does not settle, or a collection of blood under the skin that is enlarging.
  • Difficulty breathing that is new or worsening after an operation, or a nose that is obstructed on one side.
  • A change in the shape of the nose after an injury, or a nose that becomes painful and red some time after treatment.
  • Numbness or altered sensation that persists, or a scar that is thickening rather than settling.
