研究目的
To ascertain the most effective approach for laser tattoo removal using various combinations of picosecond 1064 nm, picosecond 755 nm, nanosecond 755 nm, and a fractionated CO2 laser, both with and without a perfluorodecalin (PFD) patch.
研究成果
The combination of picosecond 1064 nm, picosecond 755 nm, and a fractionated CO2 laser without the PFD patch showed superior clinical improvement over the other combinations. The addition of CO2 to this combination did not alter outcomes as no blistering occurred on any treated section.
研究不足
The study was conducted on a single patient, limiting the generalizability of the results. The use of a PFD patch demonstrated reduced efficacy in this single patient, contrary to recent literature.
1：Experimental Design and Method Selection:
A single lower extremity black tattoo was divided into 15 treatment sections to test various laser and PFD combinations.
2：Sample Selection and Data Sources:
A single patient's leg tattoo was used.
3：List of Experimental Equipment and Materials:
Picosecond Nd:Yag 1064 nm, picosecond alexandrite 755 nm, nanosecond alexandrite 755 nm, and carbon dioxide 10600 nm lasers, and a PFD patch.
4：Experimental Procedures and Operational Workflow:
Treatment sections were conducted with various laser and PFD combinations until a treatment superiority was noted.
5：Data Analysis Methods:
Clinical improvement was graded by blinded dermatologists using a grading scale of 10% intervals.
