Combined Therapy for Nevus Cell Nevus

Abstract

Effect of the Combined Laser Therapy (CLT) to nevus cellnevus was investigated. Four defferent CLTs were performed; 1)Irradiation of Pulse Laser immediately after laser epithelial peeling, 2)Irradiation of Pulse Laser immedeately after CO₂ laser and Nd-YAG Laser vapolization and laser mass reduction, 3)Irradiation of Pulse Laser after epithelium formation on the wound of laser epithelial peeling,and 4)Pulse laser irradiation after epithelium formation of the wound of laser abrasion.
Results
1) Effect of CLT1 was 65.7%
2) CLT2 was effective in lentigo and some special cases
3) Effect of CLT3 was 20%
4) Effect of CLT4 was 50%
Conclusion
In CLT1 and 2, damage of the tissue was large, and, therefore, sufficient effect was expected. Scar formation was very slight. It was plausible that the simultaneous LLLT effect of the pulse laser was combined and the wound healing was reinforced. Therefore, nevus was expected to be treated with CLT1 or 2 without scar formation which was undesirable from a cosmetic view point. CLT1 and 2 were more effective than 3 and 4.
