Adipose Stem Cell Function Maintained with Age: An Intra-Subject Study of Long-Term Cryopreserved Cells.

Background: The progressive decline in tissue mechanical strength that occurs with aging is hypothesized to be due to a loss of resident stem cell number and function. As such, there is concern regarding use of autologous adult stem cell therapy in older patients. To abrogate this, many patients elect to cryopreserve the adipose stromal-vascular fraction (SVF) of lipoaspirate, which contains resident adipose stem cells (ASC).

Adipose Derived Stromal Cell (ADSC) Injections for Pain Management of Osteoarthritis in the Human Knee Joint.

Background: This safety and feasibility study used autologous adipose-derived stromal vascular cells (the stromal vascular fraction [SVF] of adipose tissue), to treat 8 osteoarthritic knees in 6 patients of grade I to III (K-L scale) with initial pain of 4 or greater on a 10-point Visual Analog Scale (VAS).

Objectives: The primary objective of the study was evaluation of the safety of intra-articular injection of SVF. The secondary objective was to assess initial feasibility for reduction of pain in osteoarthritic knees.

Outpatient surgery and sequelae: an analysis of the AAAASF Internet-based quality assurance and peer review database.

Although Internet-based quality assurance and peer review data have demonstrated the safety of procedures performed in the outpatient setting through the analysis of outcomes, the future of patient care will be directed by evidence-based medicine. Large inpatient surgical databases have long existed to provide quality assurance and improvement data for the inpatient cohort of patients. The acquisition of large data sets related to surgical care can best be achieved through the Internet.

Reflections on lipoplasty: history and personal experience.

The author presents a brief history of the development of lipoplasty in the United States over more than 30 years. The chronology includes major clinical advances, along with the author's personal experience and the role of organized plastic surgery in defining and promoting safe practices.

Elevating the midface with barbed polypropylene sutures.

Barbed sutures, either used alone in a closed approach or as part of an open face lift procedure, may be combined with malar implants, soft tissue fillers, chemical peeling, and laser resurfacing. Because cephalad cheek repositioning affects adjacent facial areas, results may include shortening of the lower eyelid distance, flattening of the nasolabial fold, elevation of the submalar tissue, improvement of jowling, and decrease in submalar area fullness.

Suction-assisted lipoplasty: physics, optimization, and clinical verification.

Background: Although suction-assisted lipoplasty (SAL) has been clinically practiced for more than 25 years, comparatively little investigation into fundamental physics of the instrumentation used in the procedure has been conducted. Moreover, relatively little is known about the clinical impact or merit of the wide variety of instrumentation currently available.

Objective: In this study, we examined the physics related to the various components of instrumentation used in lipoplasty, and developed means to optimize performance based on quantified bench and clinical data.

Secondary lipoplasty.

Although almost all patients who undergo lipoplasty procedures experience satisfactory outcomes with rapid recovery and few complications, misuse of lipoplasty techniques and technology may lead to suboptimal results. In this article, the indications for secondary lipoplasty are outlined, a clinical classification of candidates for secondary lipoplasty is presented, and the benefits and limitations of the approaches to secondary lipoplasty are discussed.

Clinical application of VASER--assisted lipoplasty: a pilot clinical study.

Background: Although lipoplasty is the most frequently performed aesthetic surgical procedure, ultrasound-assisted lipoplasty (UAL) has not been widely adopted because of its increased potential for complications, complex and bulky instrumentation, additional cost, and steep learning curve.

Objective: We report on the use of the VASER ultrasound device in lipoplasty procedures and compare the clinical outcomes obtained by means of VASER-assisted lipoplasty with those of other UAL devices.

Methods: A superwet technique was used, and the wetting solution was uniformly distributed in the intended treatment area.
