Treatment of Telangiectasias with the 532-nm and the 532/940-nm Diode Laser

ABSTRACT

Recently, a dual-wavelength 532/940-nm laser has become available for treatment of facial vascular lesions as an alternative to the flashlamp pumped-dye lasers. Most facial vascular lesions will respond to the 532-nm wavelength. However, some of the larger and deeper lesions are resistant to this laser. The 940-nm wavelength can be used to treat these resistant lesions. Sixteen patients with 532-nm laser-resistant vascular lesions were treated with the 940-nm laser. Fourteen of these 16 patients had improvement in their telangiectasia in response to these treatments. Most facial l telangiectasias respond well to treatment with the 532-nm laser. However, some of the larger and deeper lesions will not respond well to this laser. The 940-nm wavelength laser can be used to treat these 532-nm laser resistant lesions.
