Cellulite treatment using the Nd:YAG 1440 nm wavelength laser with side firing fiber

KEYWORDS: Cellulite, Nd:YAG 1440 nm laser

SUMMARY:
Cellulite skin surface, characterized by an orange peel or mattress-like appearance, is caused by herniations of subcutaneous fat extending into the dermis, and depressions that develop within the skin layer and trabeculae in the subcutaneous fat. To evaluate the safety and efficacy of the Nd:YAG 1440nm wavelength laser a 3-step procedure to treat each structural component of cellulite was used. Eligible subjects were healthy females between 20-55 years with cellulite on their thighs of either Grade II Severe or Grade III mild or moderate on the modified Muller Nurnberger Scale. Subjects received a single treatment with a 1440 nm pulsed laser. Energy was delivered to the subdermal tissue through a side firing fiber enclosed in a cannula. Treatment by thermal

subcision targeted the hypodermal fat layer, hypodermal fat lobules that extended upward into the dermis, and fibrous septae. Clinical appearance of visible cellulite, dimples and contour irregularities was graded on a modified, validated, Muller Nurnberger Scale. Subjects were 11 healthy Caucasian non-smoking females with a mean age of 42 years (range 31-53 years). The majority (86%) showed improvement based on the evaluation of photographs taken at baseline and at the last time point. At 6-months post-treatment the average dimple average improvement score was 1.41, baseline score was 2.32, and the contour improvement score was 1.00, average baseline score was 1.86. Treatment was well tolerated. At 6-months post treatment, subject and investigator satisfaction was uniformly high, with both subjects demonstrating 100% satisfaction, score of =?5 on a 6-point Likert scale. A single treatment with the 1440 nm pulsed laser improved the appearance of cellulite.
