Updates In Scar Management Techniques

by Prof Steven Jeffery Consultant Plastic and Reconstructive Surgeon

The presence of scarring still causes many patients considerable cosmetic and functional problems with some scarring easier to treat than others.

Hypertrophic Scars

A hypertrophic scar is a thick raised scar that’s an abnormal response to wound healing. They more commonly occur in taut skin areas following skin trauma, burns or surgical incisions.

Most hypertrophic scarring improves to a certain extent with the use of scar therapy by way of massage, silicone, pressure, steroids and / or treatment with a vascular laser. There is actually little evidence for the mode of action of these modalities, but as they are (with the exception of the vascular laser) generally relatively cheap and easily available they are the treatment options offered to patients in most clinics around the world.

Once scarring has become pale (ie the redness has gone), then these options will no longer work. The scarring has ‘set’. Therefore, these modalities should be employed early.

Action is Key

In my medicolegal practice, I often advise solicitors to pay for such a course of scar therapy, only to find that by the time this gets authorised, the scarring is pale and therefore no longer amenable to such manipulation.

Difficult Scars

Some types of scars are also notoriously difficult to treat, particularly thick or dense scarring; the denser and thicker the scar the more restricting it will be to the patient. Surgical techniques of excision and resurfacing may be employed. This may be done under local or general anaesthesia, depending on the size of the scar. Tissue expanders can be used in this setting, despite the high complication rate and the prolonged discomfort and disfigurement endured by the patient, additionally, dermal substitutes may also be employed.


Fractional thermolysis, introduced by Manstein and Anderson in 2004, offers the possibility of a successful and cost-effective way of managing these difficult patients by manipulating the scar rather than excising it.

The term ‘fractional’ is used as the technique produces thousands of narrow, non-contiguous columns of thermal damage up to a depth of 4mm of the skin and scar tissue; the amount of epithelial loss is confined to the narrow diameter of the column allowing rapid re-epithelialisation i.e. healing. The micro perforations in the scarring cause an increase in its pliability and depending on the depth of penetration, may also cause a weakening of adhesions between the scar and underlying tissue such as muscle or tendon.

In 2014 eight US military dermatologists and plastic surgeons produced a consensus document that described a treatment algorithm discussing the role of various lasers in scarring following burns injury or trauma. They concluded that ‘lasers, particularly Ablative Fractional Laser, deserves a prominent role in future paradigms for scar treatment, with the possible inclusion of early intervention for contracture avoidance and assistance with wound healing’. Since then, this treatment has become routine for the management of scars that are difficult to treat with other less invasive modalities.

To Summarise

In summary, there are many surgical and non-surgical techniques open to patients with scarring. Some doctors may not be aware of some of the newer techniques.

In my opinion, every medicolegal patient with a significant scar should see a plastic surgeon who can advise on the suitability of each different technique in reducing the appearance and or functional impairment of the scarring.
