TREATMENT OF OTA NEVUS USING 2 DIFFERENT TYPES OF RUBY-LASERS

Over the past few years, ruby lasers have been found to be effective i n the treatment of deep dermal pigmented lesions of the skin, such as Ota's nevus, in addition to other superficial pigmented skin lesions, and at present, various types of laser equipment are being clinically employed. The Q-switched ruby laser is expected to supersede the conve ntional normal-pulsed ruby laser. However, we have designed a new ther apeutic protocol which involves the combined use of both Q-switched an d conventional lasers, exploiting the specific advantages of each type . This new protocol has made it possible to treat patients with Ota's nevus with a high degree of therapeutic effectiveness. In addition, it has not only shortened the time required for treatment but has also r educed patient discomfort.
