色素レーザーを用いた治療

Dye laser is a main treatment modality without operation to hemangioma simplex. We have used a dye laser device with 585nm wavelength and 4.5×10^-4 second irradiation time to this disease. Our schedule of the treatment using dye laser is as follows:test irradiation with various energy density is done to a small portion at first. Two or 3 months after that, treatment is actually begun with appropriate energy density. The results are that enough effect was obtained in the field of face and neck, but the effectiveness is unstable in that of limbs. Dye laser is much more effective to hemangioma simplex than the results of argon laser which had been used to this disease, however, this device should be improved to get higer efficiency. A dye laser device with 510nm wavelength and 3×10^-7second irradiation time was developed for treatment of brown pigmented spot,for example nevus spilus, senile pigmentation and pigmentation after trauma. We expect that dye laser will contribute further to superficial skin diseases as treatment modality without operation.
