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.
Cryolipolysis is a nonsurgical body contouring procedure that involves cooling of fat cells to induce lipolysis while sparing surrounding structures. Plastic surgery practices are increasingly incorporating noninvasive aesthetic procedures (eg, cryolipolysis, fillers, radiofrequency, ultrasound) to offer their patients a wider range of aesthetic treatment options. Here, we report insights from 8 plastic surgeons with regard to cryolipolysis best practices from a clinical perspective and the impact of integrating this noninvasive body contouring procedure into a plastic surgery practice. The authors prefer cryolipolysis over liposuction for patients who are not amenable to surgery or those who desire to avoid downtime, also taking into consideration body mass index, skin laxity, comorbidities, and risk of contour irregularities. Patient counseling is critical for setting realistic expectations regarding outcomes and should focus on the efficacy of cryolipolysis, individual variability in results, potential side effects, time course of treatment response, and the need for multiple treatment cycles. Strategies for reaching new patients and expanding services among current cryolipolysis patients are discussed.
Endoscopic stapling diverticulotomy is a safe and effective treatment method for Zenker's diverticulum and remains our procedure of choice for most patients. However, inability to safely expose the diverticulum endoscopically results in a significant abandonment rate for attempted procedures and may result in significant postoperative complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
