Argon and carbon dioxide laser treatment of hypertrophic and keloid scars.

Laser physiology has shown that while wound healing is generally excellent after laser impaction, it nevertheless is delayed. It is thought that this factor may be important in the treatment of hypertrophic and keloid scars. These scars have been treated in a variety of ways with the laser, and the results, which have been good, are reported. A possible explanation of the complex mode of action has been given. It is thought that more work should be undertaken in this field.
