A new cryolipolysis applicator effectively treated nonpinchable lateral thigh fat. Patients reported high satisfaction and visible fat reduction, with no serious adverse events, making it a safe and effective body contouring option.
Area of Science:
- Dermatology
- Aesthetic Medicine
- Medical Device Technology
Background:
- Cryolipolysis is established for various body areas, but lateral thighs present challenges due to fat accessibility.
- Traditional vacuum applicators are less effective for the "nonpinchable" fat typically found in lateral thighs.
Purpose of the Study:
- To evaluate the safety and efficacy of a prototype cryolipolysis applicator designed for lateral thigh fat reduction.
- To assess the treatment of "nonpinchable" fat deposits in the lateral thigh region.
Main Methods:
- A prospective, multicenter study involving 40 patients treated unilaterally with a prototype conformable-surface applicator for 120 minutes.
- Fat reduction was measured using ultrasound imaging and clinical photography at 2 and 4 months post-treatment.
- Patient satisfaction and physician assessments were used to evaluate outcomes.
Main Results:
- Ultrasound confirmed a statistically significant mean fat thickness reduction of 2.6 mm compared to the control thigh.
- 89% of patients would recommend the procedure, 86% were satisfied, and 86% noticed visible fat reduction.
- Independent physician review confirmed accurate identification of treatment outcomes in 87% of cases, with no serious adverse events.
Conclusions:
- The prototype cryolipolysis conformable-surface applicator is safe and effective for reducing lateral thigh fat.
- Significant fat reduction and improvement in "saddlebag" bulges were observed.
- The device offers a viable therapeutic option for improving body contouring in previously difficult-to-treat areas.
