Intralesional cryosurgery for the treatment of hypertrophic scars and keloids.

This chapter is aimed to describe in a comprehensive way the intralesional cryosurgery method to treat hypertrophic scars and keloid by a novel cryoneedle. This needle cryoprobe which is inserted into the core of the hypertrophic scar and keloid is connected to a canister of liquid nitrogen, which causes the cryoprobe to freeze thereby freezing the abutting scar tissue from the inside out.
