Occasionally scars from trauma or previous surgery heal with a result that we are unhappy with. Some patients are prone to developing keloid scars, where the scar tissue overgrows. This is more common on the shoulders, chest and ears, and is also more likely if you have darker skin.
Scars that have healed with an unsatisfactory result can be excised and re-sutured with an aim to achieve a more cosmetically acceptable result. A scar revision usually involves re-aligning the scar to fall along the naturally occurring creases on the face or excising a thick or widespread scar.
