Abstract
Background: Submental fat is a noticeable fat in the submental region that is of great concern aesthetically, especially to female patients. A 1060-nm diode laser is a clinically proven device for the laser lipolysis of subcutaneous fat cells. This study aimed to evaluate the safety and efficacy of a 1060-nm diode laser for submental fat reduction. Methods: Twenty subjects with unwanted localized submental fat were treated with a single session of a 1060-nm diode laser with an energy setting between 0.95 and 1.40 W/cm2, depending on each patient’s tolerance. Submental fat thickness measurements were documented at baseline, and 1, 3, and 6 months after treatment. Clinical photographs, ultrasound images, and adverse events were evaluated at each follow-up visit. Subjects responded to a satisfaction questionnaire at the end of the study. Results: The subjects had a mean age of 34.55 ± 6.19 years, a mean body weight of 70.66 ± 10.55 kilograms, and most (95%) were women. The average energy setting was 0.95–1.40 W/cm2, with a pain score of 3.90 ± 1.30 on a 0-to-10 scale. A significant reduction in submental fat thickness measured by ultrasound was noted at post-treatment month 3 (falling to 0.46 ± 0.13; P = 0.013). However, there was a slight increase in the submental fat thickness at the 6-month follow-up (to 0.48 ± 0.12); the change in the thickness relative to the baseline was nonsignificant (P = 0.121). Most subjects reported an improvement 6 months after the treatment. No severe adverse events were observed throughout the study period. Conclusion: Our study demonstrated the potential role of 1060-nm Diode laser for the treatment of localized submental subcutaneous adiposities. It is a promising alternative treatment modality for patients seeking an in-office, nonsurgical procedure for fat reduction without severe complications.
