Effects of Calcium Hydroxylapatite on Cellulite Dimples in the Buttocks

Twenty-five (25) subjects will be enrolled in the study. The patient's body fat composition will be measured by a digital full body composition scale, which will be used to determine the individual percent body fat and eligibility. The subjects will have three treatment sessions at weeks 0, 4, and 8 and a final live assessment visit at week 14. Office visits will last for approximately two hours. All subjects will have photographs taken before and after each treatment session. Photographs will be taken with buttocks in a relaxed and flexed state. All pictures will be taken via the Quantificare Liveviz Infinity Pro and will be stored via a HIPAA-compliant server. Subjects will be treated with subdermal injections of CaHA diluted 1:1 with normal saline solution and 1% Lidocaine after having their pictures taken. Subjects will be asked to lay in the prone position with exposed buttocks. Topical Lidocaine/Tetracaine 23%/7% ointment cream will be applied to the treatment sites. After 15 minutes of numbing, the topical anesthetic will be cleaned off with alcohol. Thereafter, subjects will be asked to stand in an upright position to easily mark the areas with cellulite dimpling. The subjects will also be asked to flex and relax their buttocks to let the physician assess the areas of dimpling. Subjects will go back to laying in prone position to receive subdermal injections of CaHA. Multiple, retrograde, linear injections using a standard 25G cannula will be performed with a threading technique by the treating physician. Post injection, a calming cream will be applied to the treated area while massaging in a circular motion for five minutes. Subjects will be called 24-48 hours after each treatment session to check up on comfort and answer questions. The treating physician will rate each subject's cellulite dimples using the Cellulite Severity Scale (CSS) at each visit. The Global Aesthetic Improvement Scale (GAIS) will be used by the treating physician and subjects to rate aesthetic improvement at each visit after baseline. Subjects will also rate their overall aesthetic improvement and treatment satisfaction at each visit after baseline according to a 5-point scale: (1) Extremely dissatisfied, (2) Dissatisfied, (3) Slightly satisfied, (4) Satisfied, (5) Extremely satisfied. Before and after photos of treated patients will be independently evaluated by the blinded, secondary physician using the CSS scale at each time interval of photos taken.
