Double chin Coolsculpting
Cryolipolysis (a.k.a. coolshaping and coolsculpting) is a non-invasive treatment that employs controlled chilling to cause apoptosis in adipocytes for fat reduction, fat removal, and body shaping. The selective damage to fat occurs because lipid-rich adipocytes are more vulnerable to cold harm than water-rich adjacent cells. Coolsculpting and cool shaping are safe and effective methods of removing subcutaneous fat and are now authorized by the US Food and Drug Administration to treat the flanks, tummy, thighs, submental region, back, bra area, buttocks area, and arms.
Cryolipolysis and CoolSculpting
Clinical trials have been done to assess the safety and efficacy of cryolipolysis (coolshaping and coolsculpting) and other subcutaneous fat removal techniques in various body areas, including the abdomen, flanks, and inner thighs, outer thighs, arms, and chest. Noninvasive submental fat removal has lately acquired popularity in cosmetic medicine due to technical developments, increasing public awareness, and a long track record of safety and efficacy for fat reduction. Recent research on coolshaping and coolsculpting of the submental region (double chin) found that the procedure was safe and well-tolerated, significantly improved neck form, and resulted in high patient satisfaction. This post will discuss Bloom et al.’s research titled “Safety and Effectiveness of Bilateral Submental Cryolipolysis With Quantified 3-Dimensional Imaging of Fat Reduction and Skin Tightening.”
Between January 22 and June 30, 2016, 14 people had submental fat reduction treatment in the lateral and central submental regions. Two cryolipolysis treatments were performed in 45-minute treatment cycles over two sessions utilizing coolsculpting/coolshaping and a small-volume cup applicator. All patients received bilateral treatments during the initial treatment session, with roughly 20% of the treatment region overlapped. Each subject got up to two treatment cycles in the lateral and central submental regions at each visit, with two treatment visits separated by six weeks. Each treatment comprised a maximum of two 45-minute chilling cycles at –11°C and a minimum of one utilizing a commercially available small-volume vacuum cup cryolipolysis applicator (CoolMini Applicator, CoolSculpting System; ZELTIQ Aesthetics). The applicator orifice is around 2.5 7.5 cm in diameter and is concave in the form to match the natural curvature of submental tissue. The participant’s head was neutralized to designate the treatment zones, and a treatment area template was positioned in the submental area’s center to achieve around 20% overlap.
Protocol for CoolSculpting therapy
The cryolipolysis therapy was performed similarly to prior research. The skin was protected with a transparent coupling gel, and then a fresh gel trap was introduced to the small-volume cup applicator (a disposable component of the applicator that prevents the gel from being drawn into the vacuum line). The vacuum suction was started, and the applicator was put over the appropriate treatment region and subsequently onto the skin. The suction sucked the target tissue to two centimeters into the cup. The vacuum force fastened the applicator to the treatment site with little pain, and fabric adhesive straps were attached to a pillow to provide further support throughout the cooling therapy. The applicator was withdrawn at the end of the treatment cycle, and the treatment area was manually massaged for two minutes to rewarm and restructure the tissue. All 14 individuals got two bilateral treatment cycles with about 20% overlap during the initial treatment visit. Due to inadequate leftover submental fat to enable two treatment cycles during the second treatment session, 12 individuals received two bilateral cycles, and two participants received one centered cycle. At the 6-week follow-up appointment, participants were evaluated to see if they would benefit from a second treatment and the number of cycles necessary to achieve the desired aesthetic result and then treated a second time. The 14 patients (12 women and 2 men; mean [SD] age, 50.5 [10.4] years) experienced very moderate side effects, including numbness and tingling, which resolved spontaneously at the 12-week follow-up examination. An independent review revealed an accurate recognition rate of 81.0 percent (95 percent confidence interval [CI], 65.9 percent-91.4 percent; P =.02) for pretreatment and posttreatment photos. Caliper measurements demonstrated a mean (SD) fat layer decrease of 2.3 (0.8) mm (range, 0.7-3.5 mm). Three-dimensional imaging revealed a mean (SD) reduction in the fat volume of 4.82 (11.42) cm3 (from 32.69 to 13.85 cm3), an increase in skin surface area of 1.29 (1.42) cm2 (from 3.18 to 0.99 cm2), and a reduction in fat thickness of 3.77 (3.59) mm (from a reduction of 13.10 mm to an increase of 0.47 mm). In participant questionnaires, thirteen persons (93 percent) indicated satisfaction with the cryolipolysis therapy. Because all participants maintained a weight change of less than 5%, no subject was excluded from the treatment effectiveness analysis due to weight change. The mean (SD) weight reduction between the initial therapy session and the 12-week follow-up appointment was 0.5 (2.3) kg (1.2 [5.0] lb). Following the conclusion of the treatment cycle and removal of the cryolipolysis applicator, photographs were taken before the manual massage of the treated region. Immediately following treatment, the photographs show the characteristic hard solidified tissue associated with the first of two bilateral treatments. Immediately following treatment, the tissue felt stiff and erythematous but was rapidly relaxed and rewarmed with manual massage. As shown in the infrared photographs, the whole tissue contained within the treatment cup cooled evenly, whereas localized warmth was noted, most likely owing to blood flow.
Weight change of 0.05 kg (0.1 lb) (0.05 percent) between baseline and 12 weeks after therapy in participant 14.
Conclusions and Consequences
While safe and effective central submental cryolipolysis (coolshaping/coolsculpting) has been described previously, this is the first clinical trial to treat cryolipolysis (coolshaping/coolsculpting) the entire submental area with overlapping bilateral sessions and shorter treatment duration. The study demonstrates that bilateral submental cryolipolysis is well tolerated and results in significant fat layer reduction, permanently resolving the double chin issue and improving overall body form.
