Erbium:YAG Laser as a Method of Deepithelization in Corrective and Reductive Breast Surgery

Abstract

Deepithelization of the breast in breast ptosis surgery is important, being associated with risks which could affect the clinical outcome. The role of Er:YAG laser deepithelization was investigated. A total of 12 bilateral mammoplasties were performed, randomly assigned to 2 groups, one of experienced and one of less-experienced surgeons. Results were compared between the 2 groups of surgeons for scalpel deepithelization on one breast and the Er:YAG laser on the contralateral breast. No complications; less edema, pain, and erythema; and quicker wound healing were observed in the laser-deepithelized breasts, with a shorter operation time even for the less-experienced surgeons. The authors do not suggest that the Er:YAG laser should replace the scalpel in the hands of the expert surgeon for breast deepithelization in breast ptosis surgery, but the results of the study suggest that Er:YAG laser ablation is a safe, precise, effective and complication-free method.

Activation of Wnt/β-Catenin Signaling Involves 660 nm Laser Radiation on Epithelium and Modulates Lipid Metabolism

“…Based on the different approaches to therapeutic interventions, biological effects and molecular mechanisms of 660 nm laser radiation on tissue are often different, for example, modulating autophagy to ensure hemostasis [ 13 ], modulating MMP-2 expression to promote angiogenic processes [ 14 ], inhibiting the FOXO1 signaling pathway to reduce oxidative stress [ 15 ], and downregulating NF-κB transcriptional activity with higher cAMP to induce inflammation [ 16 ]. Owing to its excellent features, LED light or laser has been widely used in breast surgery, for example, carbon dioxide for breast lumpectomy [ 17 ], breast ptosis surgery [ 18 ], and 3D laser imaging [ 19 ]. A major risk of light radiation to the breast may be as a contributor to breast cancer, which is the most dangerous cancer for females (4,055,770 diagnosed per year in the USA) [ 20 ].…”

Minimally Invasive Automated De-Epithelization by Precise ArF Excimer Laser Ablation

“…8 Typical IR Er:YAG microsecond pulses can ablate efficiently at fluences of hundreds of millijoules per square centimeter leading to some photothermal damage and carbonization of ejecta, which is generally acceptable for many uses in dermatology. [9][10][11] ArF excimer lasers (l¼ 193 nm, t p ¼ 20 nsec) can etch biological material with submicrometer precision without evidence of thermal effects by bond scission of the chemical constituents of the tissue matrix, followed by thermal heating 1 Instituto de Química-Física Rocasolano, CSIC, Madrid, Spain. 2 Hospital Universitario Fundació n de Alcorcó n, Alcorcó n, Spain.…”
