Laser-Assisted Liposuction Using the Novel 1,444-nm Nd:YAG Laser for the Treatment of Gynecomastia: A Pilot Study

Abstract

Background: Laser-assisted liposuction (LAL) is currently widely used to reduce localized fat. A novel Nd:YAG laser that uses a wavelength of 1,444 nm, which is better absorbed by fat, has recently been introduced. In this study, we investigated the efficacy of 1,444-nm Nd:YAG LAL for the treatment of gynecomastia. Patients and Methods: Thirteen Korean male patients (20-28 years, mean age 23 years) diagnosed with gynecomastia were enrolled in this study. All patients were treated by LAL with 1,444-nm Nd:YAG laser (100 µs pulse width, 40 Hz frequency, 300 mJ pulse energy and 12 W power with continuous emission) after tumescent anesthetic infiltration and were then evaluated. Outcome was assessed using the following 4 methods: (1) clinical assessment with photographs obtained before and 12 weeks after LAL treatment, (2) comparison of pre- and postoperative patient chest circumferences, (3) computed tomography (CT) scans to evaluate changes in breast thickness and (4) a patient satisfaction survey at the end of the study. Results: After 12 weeks, most patients (84.5%) showed an improvement greater than 50%. Mean chest circumference was significantly reduced from 109.6 ± 8.2 to 101.2 ± 4.4 cm 12 weeks after LAL (p < 0.001). CT scans showed a significant reduction in mean breast thickness from 22.7 ± 3.2 to 15.6 ± 2.4 mm (p = 0.016). Side effects (pain, edema, numbness and ecchymosis) were minimal and disappeared shortly after the first manifestation. Conclusion: Gynecomastia can be safely treated with 1,444-nm Nd:YAG LAL to reduce fatty tissue and total breast volume.

Laser-Assisted Liposuction for Autologous Fat Grafting Following Elective Breast Explant Surgery

“…Many efforts must be directed to give a pain-free experience following liposuction [26]. Researchers have always seen laser-assisted liposuction as an effective tool for pain reduction [27][28][29][30][31][32]. In our research, there was a significant positive correlation between the use of One STEP Lipo and pain reduction following liposuction, and this finding is according to the current medical knowledge [28,30,32].…”

Preclinical evaluation for removal of bulging lower eyelid fat using ultrasound‐assisted lipolysis on a Yorkshire pig

“…Lipoplasty is a technique that reshapes the body by removing unnecessary, excessively accumulated fat using suction pressure and several different devices. Several methods such as suction‐assisted lipoplasty (SAL), power‐assisted lipoplasty (PAL), LAL, and UAL have been used in cosmetic procedues 14‐18 . SAL is a classic method suitable for areas such as thighs, abdomen, forearms, and breasts.…”
