分段式雷射在皮膚科之發展與應用

The Development and Application of Fractional Laser in Dermatology

近年來，將光電或雷射等不同形式的電磁能量應用於皮膚疾病或醫學美容的治療愈趨普遍，2004年，美國哈佛大學R. Anderson and D. Manstein 等人提出fractional photothermolysis （分段式光熱療法）的理論，開啟了皮膚科雷射治療的新頁。根據分段式光熱療法的理論，各種分段式磨皮雷射也應運而生，不僅可以達到良好穩定的治療效果，更可以減少副作用的產生，本文針對分段式磨皮雷射的理論、分類、臨床應用與副作用等方面做一完整介紹。

The application of laser or photonics in dermatology or aesthetic medicine is becoming more common in these years. Various fractional lasers were developed according to the theory of fractional photothermolysis by Dr. Rox Anderson and Dr. Dieter Manstein in 2004, which has opened a new era for aesthetic laser treatment in this field. Fractional lasers, comparing with conventional lasers, have the advantages of better treatment result and less complication problems. The mechanism, classification, application, and complication of fractional lasers thoroughly discussed in this article.
