研究概览
简要总结
The purpose of this study is to evaluate histological results of the treatments with the TempSure Firm handpiece on the flanks performed in the CYN20-FIRM-LIPO study.
详细描述
Up to 10 subjects will be enrolled at up to 3 study centers. Subjects will receive 2 biopsies, 1 biopsy in the treatment area (the flanks) and 1 biopsy outside of the treatment area to serve as a control.

主要结局
Number of Treatment Samples With Different Levels of Elastin When Compared to Baseline Samples From the Same Patient
时间窗: 1 Week (7-10 days) Post Baseline
Sections of skin were removed using the punch biopsy technique to render a microscopic diagnosis. Each specimen was preserved with a fixative and then stained using Hemotoxylin \& Eosin, Verhoeff and Masson Red/Fast Green and/or nitroblue tetrazolium chloride (NBTC) staining methods. If using Hemotoxylin \& Eosin, Verhoeff and Masson Red/Fast Green staining, samples were assessed and evaluated by the amount of elastin. If using NBTC staining, samples were assessed and evaluated to differentiate between the blue-stained viable cells and the unstained thermally damaged cells. The samples were examined by a qualified pathologist. The visual changes between the treated samples and the control samples were examined, with no typical unit of measure used to quantify the difference. Simply, control and treatment images were compared to each other with a qualitative analysis of the changes. The number of samples with different levels of elastin (control compared to treatment) is reported.
