The dual 980‐nm and 1470‐nm diode laser for vascular lesions

Abstract

Transcutaneous use of dual diode lasers is a new option in dermatology. The aim of the study was to demonstrate the transcutaneous application of a dual laser in dermatologic outpatients. We used a laser system that combines 980 nm and 1470 nm wavelengths for treatment of vascular lesions. Fifty‐six adult Caucasian patients of Fitzpatrick skin type I‐III, 32 females and 24 males with mean age of (41 ± 3.7) years were included. We treated 497 vascular lesions of skin and lips. Complete clearance was achieved in cherry angiomas, venous lakes, lip hemangioma, and spider nevi in 100% after a single treatment. Patients with couperose and/or facial telangiectasia needed several treatment sessions. Mild to moderate pain during the laser shots was noted in all patients. No adverse events were recorded. The dual 980‐nm/1470‐nm diode laser is a safe and effective tool for common vascular lesions.

Advanced Materials, Structures and Processing Technologies Based on Pulsed Laser

“…In the meantime, the O peak shows a notable increase in the laser textured surface compared with that of the untreated surface, indicating the BMG surface has been oxidized along with the formation of a periodic surface structure. As indicated in [50], as the electronic structure of metal oxide facilitates the formation of hydrogen bonds and increases the surface energy, the laser textured surface typically exhibited superhydrophobicity. For the laser textured surface with heat treatment, subtle increases in C and Si peaks can be detected, indicating that hydrophobic functional groups, including -CH 2 -, -CH 3 , C=C as well as thin PDMS layer, should have been absorbed and deposited onto the laser textured BMG surface, rendering the heat-treated surface with superhydrophobicity [33,49].…”

“…This clearly indicates that the laser textured BMG surface has been oxidized along with the formation of periodic surface structure during laser texturing. As the hydrogen bonds tend to form on the metal oxide, which also increases the surface energy [50], the laser oxidized BMG surface exhibited superhydrophilicity. After heat treatment, a clear atomic percentage increase in carbon from 30.85% to 37.80% can be observed on the laser textured BMG surface with heat treatment (Figure 9c).…”

1470 nm/980 nm dual-wavelength laser is safe and efficient for the en-bloc resection of non-muscle invasive bladder cancer: A propensity score-matched analysis

“…A recently published study showed that the 1470 nm/980 nm laser is also a safe and effective tool to treat vascular lesions. 16 However, there are no published reports on the application of 1470 nm/980 nm dualwavelength lasers for the treatment of NMIBC. This current study compared the use of the 1470 nm/980 nm laser for en-bloc resection of NMIBC with conventional TURBT to evaluate the efficiency and safety of the 1470 nm/980 nm laser.…”

Dual wavelength diode laser for the treatment of lower lip venous lakes

“…The use of a newly developed dual wavelength diode laser combining 980 nm with 1470 nm has rarely been reported for the treatment of venous lakes. 5 We recently encountered a patient with venous lakes of the lower lip for 6 months and was successfully cured with the dual diode laser. The 77-year-old male patient experienced discomfort in the mouth while eating.…”
