In short. A scar assessment answers two questions: whether anything needs doing now, and what the scar is likely to do next. What it records, and when to ask.
Key points
- For a scar that is maturing normally, intervening changes the scar without knowing what it would have done on its own.
- A review date is a real answer: it commits the team to judging the scar at the point where maturation should be complete, rather than leaving the patient to wonder whether she should have asked for something.
Most scars do not need to be seen. They need time, and the honest answer for a scar that is red, raised and firm a few months after an operation is that it is doing what a scar does. The purpose of an assessment is to identify the minority that are not behaving that way, and to decide whether anything should be done now or at a defined point later.
What the assessment records
The wound history first: what operation, when, how the wound was closed, and whether anything went wrong in the first weeks. Then the scar itself: whether it is still maturing or has settled, whether it stays within the original wound, how it responds to movement, and how much tension crosses it. The site is recorded, because a scar over a joint behaves differently from one on a flat, quiet area of skin. Standardised photographs are taken at intervals, because a scar's direction of travel is much easier to judge from a series of images than from memory.
When to ask for one
Ask if a scar is growing beyond the boundary of the original wound. Ask if it is becoming increasingly painful or itchy months after it had healed. Ask if it restricts movement, or pulls a nearby feature out of position, because those are functional problems rather than appearance ones. Ask if it is not settling within the expected time. And ask if the wound became infected or healed slowly, because both make a troublesome scar more likely and change what is worth doing about it.
Most assessments end with a review date rather than a treatment

What a scar that is not behaving looks like
A scar that is still thickening well past the point it should have begun to settle. A scar that has grown beyond the original wound. A scar that has become a functional problem. A scar that is causing pain significant enough to interfere with sleep or movement. And a wound that has not closed, or that became infected, and is healing in an abnormal way. That is the list — and the reason to keep it short is that it is the list of findings that justify doing something.
What you should leave with
Clear answers to three things: whether anything needs to be done now, what the scar is likely to do next, and when it should be reviewed. If treatment is proposed, what it is expected to change and what it will not. If nothing is proposed, why not, and what would change that.
Do not wait for a review appointment if
- A wound becomes more painful, spreads red, feels hot or discharges pus, or you develop a fever — contact your treating team now, and if the team cannot be reached go to the nearest emergency department.
- A wound opens, gapes or separates.
- You become breathless, develop chest pain, or notice a swollen painful calf — seek emergency care immediately.
Frequently asked questions
When should I ask for a scar to be assessed?
If it is growing beyond the original wound, if it is causing significant pain or itch, if it restricts movement or pulls a feature out of position, if it is not settling when it should, or if the wound became infected. A scar that is merely red and raised early in maturation does not need urgent assessment.
Can a scar be assessed without an operation?
Yes, and most assessments end without one. The assessment establishes the stage of maturation, whether the scar is behaving normally, and whether treatment is appropriate now or later. For many scars the answer is time, with a review date.
Why are photographs taken?
Because scars change slowly and memory is unreliable. Standardised photographs taken at intervals are how a scar's direction of travel is judged objectively rather than from recollection, and they are what makes a decision about treatment a considered one.
Risks & Limitations
- Every operation leaves a scar. A scar is a normal result of healing, not a complication.
- A scar continues to change for twelve months or more, so its early appearance is not its final appearance.
- Hypertrophic scarring and keloid, in which a scar becomes raised, thickened, itchy or continues to grow.
- Infection, wound breakdown or a collection under the wound, any of which changes how a scar forms.
- Scar contracture, where a scar tightens and restricts movement or distorts a nearby structure.
- No treatment removes a scar. Treatment can change its width, height, colour, texture or tightness.
- Further surgery produces a new scar, which may heal better or worse than the one it replaced.
When to Seek Care
- Increasing pain, spreading redness, heat, swelling, pus or a fever from a wound — contact your treating team now, and if the team cannot be reached go to the nearest emergency department.
- A wound that opens, gapes or discharges fluid.
- A scar that keeps growing beyond the original wound, or that becomes painful or itchy months after healing.
- A scar that tightens and restricts movement, or that distorts a nearby feature.
- Breathlessness, chest pain or a swollen painful calf — seek emergency care immediately.
