Small Keloid
About Small Keloids
A small keloid is a focused raised, often itchy scar that extends over the normal surrounding skin. It may develop years after the injury and doesn’t improve without treatment. Surgical excision is often followed by recurrence (re-appearance of the keloid), particularly if surgery is not done with other treatments such as radiotherapy.
Coping with Scars
If you have skin scarring, you're not alone. Many people have scars, and there are ways to cope with them and feel more comfortable in your own skin.
Vacuum Massage
Vacuum massage is also known as depressomassage, vacuotherapy or Endermologie®. It is a non-invasive mechanical massage technique. It is performed with a mechanical device that lifts the skin by suction and creates a skin fold which can be mobilised. In the late 1970s, Louis-Paul Guitay developed the Endermologie® system (or LPG), this uses both suction (negative pressure) and mechanised rollers to mimic manual massage. LPG can provide consistent and effective treatment in a shorter time. Treatment sessions are painless and vary from 10 minutes to longer depending on the state and size of the scar.
Micro-Needling
Micro-needling is a semi-invasive technique that can be used on the face and body to achieve collagen induction (production). In this technique the skin or scar is pricked with needles to cause percutaneous collagen induction, this builds up connective tissue underneath retracted (contracted/stuck) or hypertrophic scars and wrinkles.
Pulsed Dye Laser (PDL)
The Pulsed Dye Laser (PDL) is a highly effective and low risk laser for the treatment of a wide range of vascular lesions. PDL releases brief pulses of selectively absorbed optical radiation which can cause selective damage to pigmented structures (blood vessels) and cells. The PDL is used to treat port-wine stains, facial telangiectasias and haemangioma. Newer PDLs with longer wavelengths and extended pulse durations have made deeper tissue penetration possible and improved clinical outcomes with reduced risk. PDL treatments are performed with a topical anaesthetic.
Non Ablative Fractional Laser (NAFL)
A Non-Ablative Fractional Laser (NAFL) is a non-wounding laser, it does not damage the integrity of your epidermis. NAFL uses a wavelength that does not evaporate the water in the tissue, and the energy from the laser heats the tissue in a controlled manner. Therefore, many patients prefer NAFL to ablative laser treatment. The rise in temperature stimulates the production of new collagen. By producing new collagen, the remodelling of the scar tissue is improved. Although NAFL is less invasive, requires less recovery time and has less complication risks, is not as effective as ablative laser resurfacing.
Ablative Fractional Laser (AFL)
The Ablative Fractional Laser (AFL) is a wounding laser, which delivers micro fractional columns of laser light to the top layers of the skin. This treatment works by creating thousands of microscopic areas, through heat, where the top layer of the skin is ablated (removed). These tiny areas of damage are surrounded by untreated skin, this allows healing of the skin. Traditional ablative laser resurfacing can take on average up to three weeks to heal. Types of ablative treatments include the carbon dioxide (CO2) laser and the erbium laser. AFL is performed under local anaesthesia.
Intense Pulsed Light (IPL)
Intense Pulsed Light (IPL) is not the same as a laser. IPL releases pulses of energy through light in a broad wavelength range which produces heat on the skin. A laser projects energy in a very narrow wavelength range which is more focused and therefore produces bleeding (purpura). Thanks to the broad wavelength range, IPL gives less focused heat which reduces the amount of bleeding. The light targets haemoglobin in red blood cells which aims to close the local vessels and reduce the blood supply to the growth of the scar tissue.
Surgical Scar Revision
Annually, 200 million incisions (surgical cuts) are performed worldwide. The treatment of aesthetically unacceptable scars can be challenging, although several options are available. These options vary from non-invasive options to invasive scar revision. As there are lots of options along this spectrum it is important that you seek advice for your specific concerns from a surgeon specialised in scar.
Patients often see a plastic surgeon once they have tried lots of other non-invasive options. However, sometimes there are non-invasive options that could be more appropriate than surgery; again, an assessment by your scar specialist is important.
While various surgical options exist, all surgery carries risk and therefore a full assessment is important so that you can let the surgeon know what your concerns are. The surgeon can explain all the possible procedures, the pros and cons of each one and what can or can’t be achieved with surgery. Sometimes more than one surgery will be needed and follow up after surgery is also important.
Surgical Wound Closure Techniques
The healing of cutaneous wounds after surgery is the result of a cascade of complex biochemical events that can be categorized into four overlapping phases: haemostasis, inflammation, proliferation, and remodelling. All these phases of wound healing are influenced by both intrinsic and extrinsic (inside and outside) mechanical forces which effect the tension in the skin. Evidence shows that extracellular matrix remodelling can be upset by these forces. For example, wounds over or near joints may be more likely to develop hypertrophic scars because of joint movements causing repeated tension on the wound, leading to abnormal scarring.
