Study summary

This study will evaluate the safety and efficacy of rotational fractional resection (RFR) to improve neck contouring. RFR is used to remove loose skin and fat.

Read the detailed description

This is a prospective, multi-center, single-arm (non-randomized), interventional cohort, non-significant risk (NSR) study designed to investigate the efficacy and safety of Rotational Fractional Resection (skin resection and focal lipectomy) in patients with mild to moderate submental fat and mild to moderate submental skin laxity. The total duration of study participation for each subject is approximately up to 7 months for each subject from the screening visit to the exit visit. The follow-up period will be approximately 6 months after the procedure. Eligible subjects will complete a total of 8 study visits: screening, procedure, and follow-up visits at 1, 7, 14, 30, 90 and 180 days post-procedure.

What researchers measure

Primary outcomes

  1. Number of Participants With a Reduction of Submental Skin Area ≥ 20 mm^2

    This endpoint is the difference in the measurement of submental skin area (mm\^2) between Baseline and 90 days. A reduction of ≥ 20 mm\^2 denotes improvement.

    Time frame: Baseline and 90 days post treatment

Secondary outcomes

  1. Number of Participants Who Were Satisfied With the Appearance of Their Neck and Jawline

    Subjects rated their satisfaction of the appearance of their neck and jawline on a Subject Satisfaction Questionnaire. Results reflect subjects who were satisfied ("somewhat satisfied", "satisfied", or "very satisfied").

    Time frame: 90 days after treatment

  2. Number of Participants With Post-treatment Images Correctly Identified

    Correct identification of post-treatment images by three blinded independent reviewers in more than 50% of subjects

    Time frame: Pre-treatment and 90 days after treatment
