Abstract

Blue diode laser emits a 445 nm wavelength light, which is extremely effective with hemoglobin, and has an optimal hemostatic effect. This work analyzes its thermal effects and clinical efficacy, when used to perform excisional biopsies. Forty-two excisional biopsies were performed with the laser; then, the extent of perincisional thermal effects was evaluated and patients were followed up. Average alteration on epithelial tissue was 507.07 µm, and on connective tissue was 320.39 µm. In all the cases, it was possible to obtain a histological diagnosis. Diode lasers can be safely used to perform biopsies; various intra- and postoperative advantages were confirmed.
