Adjustable Depth Fractional Radiofrequency Combined With Bipolar Radiofrequency: A Minimally Invasive Combination Treatment for Skin Laxity.

ABSTRACT: Increasingly, patients are seeking minimally invasive methods to tighten skin and remodel adipose tissue. A large treatment gap exists among 3 types of patients: (1) the younger demographic, who increasingly desire soft tissue tightening without traditional operations, scars, and downtime; (2) patients with soft tissue laxity who are not "severe enough" to justify an excisional procedure, but not "mild enough" to rely on liposuction with soft tissue contraction alone; and (3) those with recurrent laxity who already underwent traditional excisional procedures. In these populations, plastic surgeons risk under- or overtreating with traditional methods. The purpose of this supplement is to describe the utility of radiofrequency (RF) microneedling (Fractora modified to Morpheus8 InMode Aesthetic Solutions, Lake Forest, CA) in combination with bipolar RF (FaceTite/BodyTite, InMode Aesthetic Solutions). By combining these procedures, the aforementioned treatment gap can be addressed. The RF microneedling allows for subdermal adipose remodeling and skin tightening. Addition of bipolar RF also tightens the skin by contraction of the underlaying fibroseptal network in addition to induction of neocollagenesis, elastogenesis, and angiogenesis at skin surface temperatures of 40° to 50°C. In our experience, these technologies have been effective and safe in these patient populations. Level of Evidence: 4.

Project description:Background and objectivesTreatment modalities have been developed to address patient concerns with skin laxity and focal adipose excess. A previously published multicenter clinical trial reported improvement in cellulite severity after a single dermal and subcutaneous treatment on the upper thigh with a microneedle radiofrequency device. In the current study, this device was used to improve the esthetic appearance of body skin laxity and localized fat deposits above the knee, upper arms, and upper-mid back/axillary region ("bra-line").Study design/materials and methodsSubjects with cellulite, skin laxity, and/or subcutaneous adipose excess in the suprapatellar region of the anterior thigh, upper arms, and bra-line underwent a single dermal and/or subcutaneous treatment. Investigators and subjects assessed outcome at 1-, 3-, and 6-month follow-up, using 5-point Likert scales for global esthetic improvement, skin laxity improvement, and satisfaction.ResultsIn total, 31 females (mean age 51 ± 9 years) with Fitzpatrick skin types I-IV received a single treatment on 62 treatment areas: 22 upper arms, 34 suprapatellar, and 6 bra-lines. Investigator assessments at 1, 3, and 6 months for global esthetic improvement and skin laxity for the upper arms and bra-line demonstrated improvements in 100% of subjects at all timepoints; for the suprapatellar region, these values were 69%, 92%, 65%, and 85%, 92%, 65%, respectively. Investigator satisfaction at each timepoint was satisfied or very satisfied in 80%, 100%, 90% for upper arms; 80%, 80%, 80% for bra-line; and 50%, 81%, 65% for suprapatellar region. Subject self-assessments at 1, 3, and 6 months for global esthetic improvement and skin laxity for the upper arms demonstrated improvements in 100% of subjects at all timepoints; for the bra-line, these values were 40%, 60%, 80%, and 60%, 60%, 80%, respectively; for the suprapatellar region, these values were 81%, 92%, 88%, and 69%, 85%, 88%, respectively. Subject satisfaction at each timepoint was satisfied or very satisfied in 80%, 100%, 100% for upper arms; 40%, 40%, 80% for bra-line; and 50%, 77%, 65% for suprapatellar. Treatments were well tolerated with subjects reporting transient erythema and edema associated with 69% and 46% of treatments, respectively. Mild bruising, resolving within 5 days, was reported after 32% of the treatments.ConclusionMicroneedle fractional radiofrequency provides a single treatment protocol to improve the esthetic appearance of body skin laxity and localized adipose excess to the upper arms, bra-line, and suprapatellar regions. Further study is warranted to evaluate the degree of improvement and long-term effect beyond 6 months post-treatment. Lasers Surg. Med. © 2021 The Authors.

Project description:Nonexcisional facial skin tightening has long been an elusive goal in aesthetic surgery. The "treatment gap" includes cases who are not "severe" enough for excisions surgery but not "mild" enough for most traditional noninvasive aesthetic modalities. In this retrospective review, we present the largest evaluation to date of radiofrequency (RF) skin tightening technology combination including bipolar RF (FaceTite; InMode) and fractional bipolar RF (Fractora modified to Morpheus8; InMode).MethodsA multicenter retrospective study was conducted between January 2013 and December 2018 using a combination of bipolar RF and fractional bipolar RF for the treatment of facial aging. Data collection included demographic information, Baker Face/Neck Classification, amount of energy used, adverse events, and patient satisfaction. Four cadaver dissections were also conducted to correlate the underlying neuromuscular anatomy with RF treatment of the lower face and neck.ResultsTwo hundred forty-seven patients (234 women and 13 men) were included in the study. Average age was 55.1 years (SD, ±8), body mass index was 24.3 (±2.4), and 9% (23/247) of patients were active smokers at the time of treatment. Patients had an average Baker Face/Neck Classification score of 3.1 (SD, ±1.4). The procedure was performed under local anesthesia in 240/247 cases (97.2%). Patients objectively improved their Baker Face/Neck Classification score by 1.4 points (SD, ±1.1). Ninety-three percent of patients indicated that they were pleased with their results and would undergo the procedure again. Complications recorded for our cohort included prolonged swelling >6 weeks (4.8%, 12/247), hardened area >12 weeks (3.2%, 8/247), and marginal mandibular neuropraxia (1.2%, 3/247), which all resolved without further intervention. When considering possible control variables, age seems to be a significant factor. That is, older patients were more likely to benefit from a larger magnitude of the treatment effect (as demonstrated by a decrease in the Baker rating from pre- to posttreatment) when compared with younger patients. However, both groups did demonstrate significant improvements across time.ConclusionWhile this combination RF treatment (FaceTite bipolar RF and fractional bipolar RF) does not aim to replace a facelift/necklift in appropriate candidates, it does broaden the plastic surgeons' armamentarium to potentially fill a treatment gap.

Project description:Purpose To develop and demonstrate in vitro and in vivo a single interventional magnetic resonance (MR)-active device that integrates the functions of precise identification of a tissue site with the delivery of radiofrequency (RF) energy for ablation, high-spatial-resolution thermal mapping to monitor thermal dose, and quantitative MR imaging relaxometry to document ablation-induced tissue changes for characterizing ablated tissue. Materials and Methods All animal studies were approved by the institutional animal care and use committee. A loopless MR imaging antenna composed of a tuned microcable either 0.8 or 2.2 mm in diameter with an extended central conductor was switched between a 3-T MR imaging unit and an RF power source to monitor and perform RF ablation in bovine muscle and human artery samples in vitro and in rabbits in vivo. High-spatial-resolution (250-300-?m) proton resonance frequency shift MR thermometry was interleaved with ablations. Quantitative spin-lattice (T1) and spin-spin (T2) relaxation time MR imaging mapping was performed before and after ablation. These maps were compared with findings from gross tissue examination of the region of ablated tissue after MR imaging. Results High-spatial-resolution MR imaging afforded temperature mapping in less than 8 seconds for monitoring ablation temperatures in excess of 85°C delivered by the same device. This produced irreversible thermal injury and necrosis. Quantitative MR imaging relaxation time maps demonstrated up to a twofold variation in mean regional T1 and T2 after ablation versus before ablation. Conclusion A simple, integrated, minimally invasive interventional probe that provides image-guided therapy delivery, thermal mapping of dose, and detection of ablation-associated MR imaging parametric changes was developed and demonstrated. With this single-device approach, coupling-related safety concerns associated with multiple conductor approaches were avoided. © RSNA, 2016 Online supplemental material is available for this article.
