Energy based devices have been developed for the purposes of tissue contraction and skin tightening. Its application in the face and neck have been explored using lasers, temperature controlled monopolar and bipolar radiofrequency, and ultrasound. The purpose of this chapter is to explore the various applications for the face and neck using Renuvion™, a unique energy driven device based on plasma generated from the combination of helium gas and radiofrequency energy. The advantage of this technology is its ability to offer precise delivery of heat to tissue with minimal thermal spread, in part due to the rapid cooling aided by the helium gas. We will explore the options in which this technology can be incorporated to rejuvenate the face and neck, the patient selection considerations in choosing method of approach, surgical technique, anticipated outcomes, potential concerns and or complications associated with this and expected perioperative care. Applications in the face and neck include: (1) Subdermally in the neck as a stand alone procedure with or without liposuction. (2) Subdermally in a limited incision, non-excisional technique with a concomitant platysmaplasty either with an open approach or percutaneous use of suture suspension for the platysmal muscle. (3) Subdermally in conjunction with an open traditional rhytidectomy involving skin excision. (4) Ablative resurfacing—fractional or pulsed and full continuous modalities (non-FDA cleared at the time of this writing). It is the authors’ experience that with appropriate patient selection this can be a powerful tool that can deliver skin tightening and rhytid reduction not seen by other technologies available.

The Given

Laser liposuction was developed as minimally invasive liposuction technique where energy breaks adipocytes (comparing with traditional liposuction where disruption is manual). After its implementation in the early 1990s, various academic reports were published that showed superiority of the laser assisted liposuction over standard tumescent technique. After tissue damage with photo-optical thermal energy, histological changes result in adipocyte disruption, blood vessel coagulation and neocollagenesis. The clinical manifestation of the latter is significant skin tightening and faster and more comfortable recovery. The diameter of the laser fiber is very small. Therefore, it is possible to reach adipose tissue entrapped in fibrotic areas and also superficially under the skin. The lysis of the given adipose tissue enables the subsequent suction with microcannulas. That explains the widespread use of the laser-assisted liposuction in the face and neck. Due to the significant skin tightening, the procedure can be done solely for rejuvenation purposes and is called endolight lifting. The possibility to reach fat in the fibrotic areas makes laser-assisted lipolysis/liposuction ideal procedure for contouring irregularities from previous body contouring procedures.

Background. One of the most frequent complications of aesthetic correction methods is the problem of contouring, visualization, or local tightening of the skin at the sites of administration of the agent based on calcium hydroxyapatite, which occurs in violation of the injection technique. Aim: to study the efficiency of the combined method including a course of diadynamophoresis of collagenase 1000 KE (collagenase units) and a fractional CO2 laser procedure in correction of a surface-injected preparation in late terms. Methods. Clinical and instrumental examination of 24 women (average age 38.2 3.5 years) was conducted. All patients complained of complications after the contour plastic surgery procedure using a preparation based on calcium hydroxyapatite, in the form of contouring of the preparation and superficial skin tightening on the face at the filler injection site. Results. When comparing the control, main and reference groups, it was revealed that the combined use of collalysin diadynamophoresis and fractional CO2 laser at low parameters improves significantly the quality of life in terms of the adapted dermatological index. Clinical improvement was registered in all groups, but it was most significant in the main one, which correlated with the data of ultrasound examination with a 33 MHz sensor. In the main group, faster biodegradation was noted, and the volume of the surface-injected filler decreased 2.5 times after 1 month and 6 times after 2 months. Conclusion. The combined use of collalysin diadynamophoresis and a fractional CO2 laser is an effective complex for the correction of complications after contour plastic surgery of fillers based on calcium hydroxyapatite.

Lymphocytic Infiltrates

Abstract Background Over the past several years, hyperdilute calcium hydroxylapatite (CaHA) has emerged as an effective modality for improving skin quality and managing laxity in the face, arms, hands, neck, décolletage, upper arms, abdomen, buttocks, and upper legs, as well as treating cellulite and striae. While undiluted CaHA is used to provide volume, hyperdilute CaHA is distributed across a much larger surface area in a more superficial plane to stimulate neocollagenesis and elastin formation over time. The absence of lymphocytic infiltrates and predominance of type 1 collagen in the tissue response to CaHA make hyperdilute CaHA a valuable tool for nonsurgical skin tightening. Objectives Provide practical step-by-step guidance on patient selection, dilution practices, and optimal injection technique to facilitate incorporation of the technique into clinical practice. Methods Over the course of 3 regional meetings in the United States, 12 expert physician injectors participated in live webinars as part of a continuing medical education program. Results The practical guidance in this manuscript is based upon the most frequently requested information by audience members and the information considered critical for success by the authors. Conclusions The minimally invasive nature of filler injection results in little down time, making this treatment particularly appealing. The recommendations presented are consistent with previously published consensus guidelines on hyperdilute CaHA but are intended to serve as “how-to” guidance from experience of expert injectors who have successfully treated the face and body.

Zero Sum

AbstractZero-sum thinking and aversion to trade pervade our society, yet fly in the face of everyday experience and the consensus of economists. Boyer & Petersen's (B&P's) evolutionary model invokes coalitional psychology to explain these puzzling intuitions. I raise several empirical challenges to this explanation, proposing two alternative mechanisms – intuitive mercantilism (assigning value to money rather than goods) and errors in perspective-taking.

Impact Erosion

AbstractThe clear evidence of water erosion on the surface of Mars suggests an early climate much more clement than the present one. Using a model for the origin of inner planet atmospheres by icy planetesimal impact, it is possible to reconstruct the original volatile inventory on Mars, starting from the thin atmosphere we observe today. Evidence for cometary impact can be found in the present abundances and isotope ratios of gases in the atmosphere and in SNC meteorites. If we invoke impact erosion to account for the present excess of129Xe, we predict an early inventory equivalent to at least 7.5 bars of CO2. This reservoir of volatiles is adequate to produce a substantial greenhouse effect, provided there is some small addition of SO2(volcanoes) or reduced gases (cometary impact). Thus it seems likely that conditions on early Mars were suitable for the origin of life – biogenic elements and liquid water were present at favorable conditions of pressure and temperature. Whether life began on Mars remains an open question, receiving hints of a positive answer from recent work on one of the Martian meteorites. The implications for habitable zones around other stars include the need to have rocky planets with sufficient mass to preserve atmospheres in the face of intensive early bombardment.
