intralesional injection- keloids, scars, Contractures

Keloids, Scars, and Contractures are commonly a result of problems that occur in physiologic wound healing and may cause lesions in the dermis. Excessive scarring often arises from procedures like elective and trauma operations and can lead to physiological and psychological consequences for the patient. As such, surgical incisions have to be precisely planned and thought out to prevent the occurrence of such contractures. Scar contractures often come from large open wounds, while hypertrophic scars come from an abnormal response to an injury or trauma. Keloids, on the other hand, begin as hypertrophic scars and gradually extend to other areas. Thus, the two may often be challenging to differentiate and distinguish from one another.

An Intralesional Injection is considered the standard treatment for most skin diseases or conditions. It is designed to deliver a specific concentration of a specific medicine to the area where the skin lesion is found to promote healing while minimising harmful side effects. Corticosteroids like triamcinolone acetonide are commonly used for this type of injection to treat the scarred area. Depending on the type, location, and size of your lesion or your overall situation, the dosage of the medicine used for the injection will vary. Triamcinolone acetonide is typically available in 10mg/mL, which is ideal for hypertrophic scars with moderate thickness, or 40mg/mL used for large keloid scars. Getting the right injection dose is important to treat your condition properly, so before you can get any injection, your doctor must first examine your skin condition and view your medical history to check for contraindications. Intralesional injections are not suitable for patients with allergy to the corticosteroid and should not be administered in areas with active skin infections.
