ルビーレーザーで治療に困難を感じる症例の治療法とその治療上の工夫

抄録

In the past several years, Q switched ruby lasers have been found to be effective in the treatment of deep dermal pigmented lesions of the skin, especially Ota's nevus. The recently developed Q-switched ruby laser is already to supersede the conventional therapeutic procedures such as dry ice, skin abrasion or skin grafting treatments, patients who had been treated by those procedures, which are difficult to treat, are also treatable with ruby laser. In those patients, it needs more times of irradiation and it takes about from 2 years to 3 years which requires 1 more year to diminish the lesion completely. However, we have designed a new therapeutic protocol which involves the combined use of both Q-switched and conventional normal-pulsed lasers, exploiting the specific advantages of each type.
