Surgery and Laser Treatments in Dermatology

The document from 2003 reports on various studies concerning laser treatments and their effectiveness in dermatology. One study with 29 patients showed that CO₂ lasers were effective in treating angiofibromas in 77% of cases but caused persistent hypertrophic scarring in 23%. Another highlighted the need for careful selection of laser and IPL treatments for Asian patients to prevent pigmentary issues. Over 3000 scalp surgeries were reviewed to provide technical guidelines for avoiding complications. A study on leg telangiectases treatment with a 532 nm KTP laser reported significant clearing with minimal adverse effects. Additionally, a study of 821 patients found that 3.5% developed leukotrichia after IPL and laser hair removal, with some experiencing an acceleration of white hair development. A study of 142 women receiving facial massages reported various skin benefits, despite 43% experiencing erythema and puffiness. Lastly, a study with 19 patients demonstrated that botulinum toxin type A significantly reduced sweat production in palmar hyperhidrosis with a high success rate and few mild adverse events.
