[Laser surgery in dermatology. Risks and chances].
With the introduction of selective photothermolysis with pulsed laser irradiation, the quality of the dermatological laser therapy was clearly improved in the past decade. Above all the high risk of scar formation was clearly reduced. To minimize the fundamental risks that laser surgery entails such as hypo- and hyper pigmentation and scar formation, the indication should be checked precisely before any treatment. In addition, the physician must be aware of the specific side effects of the laser and its correct application. For the dermatologist, there is a wide range of indications on two levels: medical treatment of skin diseases and on the other side the use of laser technology for treatment of cosmetic-aesthetic skin disorders. Laser devices with the same effect and side effects are used for both indication groups. Thus dermatologic training should cover all laser indications.
