Collagenase-Assisted Fat Dissociation for Autologous Fat Transfer

DERMATOLOGIC SURGERY, Issue 10 2008
DAVID K. MOSCATELLO PHD
BACKGROUND The quality of fat for autologous transfer procedures has been a major focus of research in the past few years. The primary goal of these efforts is to improve the viability and longevity of the graft in human subjects. One possible factor in the permanence of theses transplants is the size of the adipose tissue grafts. OBJECTIVE This study evaluated the effects of collagenase digestion on the viability of human adipose tissue. MATERIALS AND METHODS Samples of fat were obtained from subjects undergoing tumescent liposuction. The tissue was digested in a variety of concentrations of collagenase using optimized methods of processing. The digested fat was also subjected to mock injections through small bore needles. RESULTS Eight subjects completed the study. The viability of the fat using the optimized methods of collagenase digestion was consistently higher than 79%. During the mock injection trials, the viability of fat was improved from approximately 17% to 84% by collagenase digestion. CONCLUSIONS Our results show increased viability of human adipose tissue when digested by collagenase. These techniques can be applied to human autologous lipoaugmentation procedures in an effort to improve longevity of the transplanted tissue. [source]

William Hanke MD
Background. This study was created by the Accreditation Association for Ambulatory Health Care Institute for Quality Improvement to measure clinical performance and improvement opportunities for physicians and ambulatory health-care organizations. Data were collected prospectively between February 2001 and August 2002. Thirty-nine study centers participated, and 688 patients who had tumescent liposuction were surveyed and followed for 6 months. Objective. The objective was to determine patient satisfaction with tumescent liposuction and examine current liposuction practice and the safety of tumescent liposuction in a representative cohort of patients. Methods. The Accreditation Association for Ambulatory Health Care Institute for Quality Improvement collected prospective data from February 2001 to August 2002 from 68 organizations registered for this study. Ultimately 39 organizations submitted 688 useable cases performed totally with local anesthesia, "tumescent technique." Results. The overall clinical complication rate found in the Accreditation Association for Ambulatory Health Care Institute for Quality Improvement study was 0.7% (5 of 702). There was a minor complication rate of 0.57%. The major complication rate was 0.14% with one patient requiring hospitalization. Seventy-five percent of the patients reported no discomfort during their procedures. Of the 59% of patients who responded to a 6-month postoperative survey, 91% were positive about their decision to have liposuction (rating of 4 or 5 on a scale of 1,5) and 84% had high levels (4 or 5 on a scale of 1,5) of overall satisfaction with the procedure. Conclusions. Our findings are consistent with others in that tumescent liposuction is a safe procedure with a low complication rate and high patient satisfaction. [source]

The Laser-Assisted Neck Lift: Modifications in Technique and Postoperative Care to Improve Results

F. Richard Noodleman MD
background. Conventional submental tumescent liposuction has proved disappointing for some patients with anterior neck laxity, ptotic platysma muscles, and increased subplatysmal fat. Many of these patients are facelift candidates but are unwilling to undergo this extensive procedure. We describe our hybrid approach, which offers consistently improved results and enhanced patient satisfaction. objective. To establish a sharper cervicomental angle by more completely removing subplatysmal fat. We also wished to achieve more consistent, smoother results, minimizing ripples, folds, and hematomas with a novel postoperative dressing system. methods. Extensive tumescent liposuction of the lower face, jowls, and anterior neck was performed. Following this, subplatysmal fat was removed by dissection, the platysma muscle was imbricated, and the CO2 laser utilized in a defocused, low-power mode to partially treat the dermal undersurface and underlying muscle. Our postoperative dressing included a 10 cm mineral oil polymer gel disc in the submental location, covered by tape, silicone foam, and a lower face and neck garment to provide both support and even compression over the entire neck for at least the first 24 hours. results. Results proved uniformly satisfying for most patients, even those in their senior years. Benefits included an improved cervicomental angle, a decrease in jowling, and a marked reduction in the laxity and wrinkling of the neck skin and horizontal neck creases. Problems related to postoperative rippling or folding of the redraped skin and hematoma formation were minimized. conclusion. Laser neck tightening combined with tumescent liposuction and an advanced postoperative dressing for superior support and uniform compression has resulted in consistently excellent outcomes with improved patient satisfaction.

Powered Liposuction: An Evaluation of Currently Available Instrumentation

DERMATOLOGIC SURGERY, Issue 5 2002
Timothy Corcoran Flynn MD
background. Over the past several years, powered liposuction instruments have become available to the dermatologic surgeon. These instruments all move the cannula forward and backward 2,12 mm with rapidity. This motion simulates the standard human movement of the cannula and facilitates movement through the tissue. Powered liposuction may help to prevent surgeon fatigue and has recently been shown to aid in the efficacy of fat removal. objective. To compare and contrast currently available powered liposuction instruments, to obtain objective engineering data on the instruments, and to compare the instruments when used on actual liposuction cases. methods. Five currently available powered liposuction systems were evaluated by the author. Each instrument was used with a 3 mm dual side port cannula on patients undergoing tumescent liposuction. An independent engineering firm, who collected objective measurements such as weight, stroke force, temperature, and vibration measurements on the instruments, evaluated the units. Noise measurements were obtained. results. Each of the five systems showed advantages and disadvantages. Important issues were the size and weight of the units, as well as whether they were driven electrically or pneumatically. Stroke force is variable (range 9.5,30 pounds). The noise of the units ranged between 60 and 87 dB. Vibration measurements varied from instrument to instrument. Units produced a variable amount of heat ranging from 77°F to 102°F. Most instruments are autoclavable, and one system is disposable. Build quality and reliability varied with the instrument. conclusion. Instruments for powered liposuction have emerged in the last 2 years, with each instrument having distinct advantages and disadvantages. This article reviews five currently available powered liposuction instruments and presents objective measurements as well as the author's experience using the instruments. [source]

Numerous American dermatologic surgeons have had a major impact on scientific and technological discoveries in cutaneous surgery. Dermatologic surgeons have been significantly involved in cutaneous surgery since the second half of the 19th century. Dermatologic surgeons have contributed many important advances to the fields of chemical peeling, cryosurgery, dermabrasion, electrosurgery, hair transplantation, soft tissue augmentation, tumescent liposuction, laser surgery, phlebology, Mohs chemosurgery, cutaneous reconstruction, wound healing, botulium toxin, blepharoplasty, and rhytidectomy. Conclusion. Dermatologic surgeons in the United States have contributed significantly to the history of reconstructive and cosmetic surgery. Dermatologic surgeons have been leaders in advancing this field and are poised to continue in the future. [source]

Nitrous oxide as an adjunct in tumescent liposuction

JOURNAL OF COSMETIC DERMATOLOGY, Issue 4 2005
Garrett Bird
Summary Background, Nitrous oxide (N2O) has been used as an anesthetic for over 300 years. It is safe, easy to use, and effective. In this article we will document N2O use as an adjunct to tumescent liposuction. The history, mechanism of action, use, and safety in ambulatory surgery of N2O are reviewed. Objective, The authors intend to review the history of both tumescent liposuction and N2O in surgery, discuss the possible adverse reactions, and present guidelines for the use of N2O during tumescent liposuction. Methods, A Medline review of articles, 1966,2004, related to N2O was performed, using the search terms nitrous, oxide, safety, toxicity, mechanism, anesthetic, surgery, risks, and delivery. Articles that were cited by the authors of this subset of original articles were also used when appropriate. Articles were rated and included based on date of publication, level of evidence, and applicability to tumescent liposuction. Results and conclusions, Nitrous oxide is safe, easily administered, inexpensive, and is an effective adjunct to tumescent liposuction. It provides a high level of pain control, and is patient controlled, while not putting the patient at risk of full anesthesia. When used correctly, with proper equipment, it poses little risk to either patients or healthcare workers. [source]
