“…Recalling that the total ability to re-drape the skin is related to the contractile nature of the dermis, as reflected by dermal thickness, the amount of FSN and fat to be aspirated, the delivery of RF energy to multiple tissue planes has proven advantageous. Treating the immediate subdermal layer leads to neo-collagenesis and subdermal remodeling, while treating above and below Scarpa's fascia maximally augments fat liquification, coagulates blood vessels, and creates an active fibroblastic reaction that replaces liquified fat [15,16], neo-angiogenesis, and a compact, reorganized layer of collagen and elastin over 4-6 months [17]. The delivery of immediate heating between 60 and 80°C causes collagen fibrils to contract to one third their length and alters the microenvironment of the extracellular matrix toward favorable remodeling and healing.…”

Enhanced Liposuction - New Perspectives and Techniques

View full text Add to dashboard Cite

Body contouring with liposuction has evolved significantly from the early approach of simply debulking excess fatty tissue, to affecting the mechanical properties of different tissue types and layers. Operative paradigms have been expanded to apply energy-based technologies intraoperatively to provide more uniform aspiration, selective fatty tissue emulsification in soft and fibrous body areas, minimize trauma to nerves and vessels, expose the fibrous septal network, reduce operator fatigue and help deliver smooth shapes with less discomfort and bruising. Advanced refinements with the delivery of monopolar and bipolar radiofrequency energy for soft tissue heating have been shown to reduce the residual soft tissue laxity that often follows voluminous fat removal. The Renuvion® (Apyx™ Medical, Clearwater, FL) radiofrequency powered helium plasma technology introduces an emerging concept in which the delivery of subdermal thermal energy preferentially coagulates the fascia and fibrous septal network through a conductive helium plasma stream seeking the path of least resistance, which in turn results in collagen contraction and tissue shrinkage that permits re-draping of the skin and enhanced definition. The physics and mechanics of Renuvion® subdermal soft tissue coagulation will be presented, along with clinical applications that have provided the authors more contouring finesse and has augmented liposuction outcomes.

“…Maximum collagen contraction occurred within 0.044 seconds [2,26]. The rapid rise to 85° Celsius is important as 10 times more time is needed to contract collagen for every 5° drop in temperature [17]. This makes Renuvion® technology very efficient compared to many other technologies.…”

“…15 Studies demonstrate that subdermal temperatures from 65 to 68°C and skin surface temperatures from 38 to 42°C are required for optimal contraction, and thus temperature regulation is essential during RF procedures. 16 Each of the manufacturers for the devices discussed in this review has developed recommendations with regard to techniques that aid in prevention of epidermal burns, to be discussed below.…”

Radiofrequency Rejuvenation of the “Tweener” Patient: Under, Over, or Through the Skin

2021

View full text Add to dashboard Cite

The demand for noninvasive facial rejuvenation continues to increase as younger, well-informed patients enter the aesthetic market. We refer to a subset of these patients as “tweeners,” those who present with early signs of neck and facial aging, but who have not yet developed changes significant enough to warrant a traditional excisional surgery approach. Many of these patients are in search of a minimally invasive intervention, a bridge in between observation and surgery. The authors describe their experience with radiofrequency (RF) technology as an in-office tool to address the aging face in a select patient population. This review also attempts to comprehensively search the existing body of literature to describe the RF technologies and devices available for facial rejuvenation. The efficacy and safety profiles of the devices are discussed, and the devices are categorized by their method of RF delivery—over (contact), through (microneedle), and under (percutaneous) the skin.

“…Minimally invasive skin tightening and fat reduction have been extensively studied in the past. [1][2][3] Utilizing lasers, radiofrequency (RF), and ultrasound technology, the list of commercially available devices continues to expand (►Table 1). Over the past two decades, RF technology has steadily increased in popularity every year.…”

“…Recently, fractional RF devices, such as Fractora (Invasix, Yokneam, Israel), can provide variabledepth and variable-density needle-based tips to improve both dyschromia and texture in the neck. 2 This device works through RF energy and a positive charge from each pin, resulting in an ablative crater and a zone of nonablative thermal coagulation (►Fig. 1).…”

Minimally invasive in-office procedures are a fast growing field in plastic surgery. Patients often notice and complain about their neck at an earlier age. Modern treatments for the aging neck have continued to evolve over the past decade, with more options continuing to become available. In this article, we describe our noninvasive approach to the aging neck through the combination of submental liposuction, radiofrequency (RF) microneedling, and percutaneous RF as a safe and effective option. Through appropriate patient selection, preoperative counseling, and good surgical technique, appropriate results can be achieved with minimal downtime. Patient selection, counseling, appropriate anesthesia, procedure details, and results are discussed in this article.
