題 目:青春痘疤痕之光電治療原理與實例探討
             Optical and electrical based treatment of acne scar: Principles and practice

大綱:
Part I. Overview of acne scar treatment
Types of acne scar
    1. Hypotrophic/atrophic scar
          icepick
          boxcar
          rolling
    2. Hypertrophic scar

Rationale of optical and electrical based treatment for atrophic acne scar
   1. Removal of scar tissue
         Devices:
            Traditional ablative lasers: removal of bulky tissue
            Fractional photothermolysis: shorten downtime
            Nitrogen plasma (PSR: plasma skin rejuvenation)

   2. Stimulation of collagen remodeling
         Wound healing process
         Cytokines of wound healing
         Effect of fractional CO2 laser on cytokines
        
Part II. Laser tissue interaction
Laser tissue interaction
   photochemical interaction
   thermal interaction
   photoablation
   plasma-induced ablation
   photodisruption
Tissue thermal reaction
Selective photothermolysis
Resurfacing lasers
Fractional photothermolysis
