Use of high-power diode laser at 1060 nm for the treatment of vascular lesions

Abstract

The use of 1060-nm wavelength light emitted from a high-power diode laser is a novel method for the removal of vascular lesions. Two Caucasian women with Fitzpatrick skin phototype II, who had various vascular lesions, were treated with a 1060-nm high-power diode laser, applying a fluence of 120 J/cm2 and a single pulse duration of 74 milliseconds. Immediate results were that the cherry angiomas became dark and a scab was formed (that remitted 2 weeks after treatment); the telangiectasias and venulectasias disappeared immediately. This technology has reported effective and safe results for removing different types of vascular lesions in the two patients treated. Side effects were those expected for this technique.

The Effect of an Optical Clearing Agent on Tissue Prior to 1064-nm Laser Therapy

“…It has been reported that while the Nd:YAG laser shows a high therapeutic effect, the diode laser of the same wavelength is cheaper than the Nd:YAG laser with reduced cost and high efficiency. 5,6 Although the length of a diode laser coherence is shorter than that of a Nd:YAG laser coherence, much absorption occurs from the outer skin, thus limiting the transmission depth of light energy. Due to such restriction, many patients complain of fever on the surface of the skin during a high-power treatment with a diode laser.…”

“…Due to such restriction, many patients complain of fever on the surface of the skin during a high-power treatment with a diode laser. [1][2][3][4][5][6] To solve such problem, the objecteive of this study was to determine whether the treatment efficiency of a diode laser could be improved by using an optical clearing agent (OCA). Research is being actively conducted to transmit light deeply to living tissues in treatment using a laser.…”

Approach of Multiple Endocrine Neoplasia Type 1 (MEN1) Syndrome–Related Skin Tumors

“…Usually asymptomatic, cherry angiomas can potentially become a certain reason for concern from a cosmetic point of view. Several therapeutic approaches have been suggested including light-based devices such as Nd:YAG laser, intense pulsed light, and pulsed dye laser, as well as other non-laser options including sclerotherapy, cryotherapy, or electrotherapy [ 104 , 107 , 108 ]. Even though acromegaly represents an infrequent part of MEN1, with a penetrance of 10% due to its severe impact, the diagnosis of such skin findings should not be overlooked [ 1 , 109 , 110 , 111 , 112 ].…”
