Carbon dioxide therapy: effects on skin irregularity and its use as a complement to liposuction.

For a successful conventional or superficial liposuction, it is necessary to consider the competence of the surgeon who is to administer the procedure necessary for this type of surgery as well as the physical and psychological evaluation of the determined patient. A poor result often is related to the persistence of adipose tissue irregularity in the form of fatty tissue accumulation. This complication, common to this type of surgery, has called for research to determine methods for its treatment. Carbon dioxide (CO2) therapy refers to the transcutaneous and subcutaneous administration of CO2 for therapeutic purposes. This treatment originated at the Royal Spas of France in 1932 with the treatment of patients affected by obliteration of arteriopathies. Recent studies have demonstrated the effect of subcutaneous CO2 therapy performed to improve local parameters of circulation (performed by Doppler, laser-Doppler, and trans-cutaneous partial pressure of oxygen determination), and to reduce localized adiposities (verified reporting variations in maximum circumference and performing histologic studies). With these results, the absence of toxicity, and the relevant side effects related to this treatment taken into consideration, the Plastic Surgery Unit of Siena has been committed to researching the role that CO2 therapy can play in the treatment of skin irregularity and as a complement to liposuction. The authors report their experience using Carbomed programmable automatic CO2 therapy apparatus and 30GA1/2 0,3X13 microlance needles for the treatment of patients with adipose tissue accumulations located on the thighs and knees. In their study, 42 patients were divided into three groups: A, B, and C. In Group A, only liposuction was performed. In group B 3 weeks after liposuction CO2 therapy was administered in two weekly subcutaneous applications of CO2 for 10 consecutive weeks. In group C, CO2 therapy alone was administered with the same contingencies used for group B (two weekly subcutaneous applications of CO2 for 10 consecutive weeks). The objective was to assess the effectiveness of CO2 therapy for skin irregularity and as a complement to liposuction for adipose tissue accumulation by reporting variations in circumference and skin elasticity monitored by the Cutometer SEM 474 in all treated areas. The data obtained were analyzed statistically. Values of p less than 0.05 were considered significant. The authors report their experience and the results achieved from the study.

What makes buttocks beautiful? A review and classification of the determinants of gluteal beauty and the surgical techniques to achieve them.

BACKGROUND: No reports can be found in medical literature describing the anatomic details that make the buttocks beautiful, nor the defects in this region that can help the surgeon decide whether gluteal prostheses are necessary or not, and, if so, which type, design, and volume of prostheses should be used, in which plane they should be placed, and so forth. METHODS: The authors studied 1,320 photographs of nude women and measured 132 female patients ages 16 to 62 years. They found that four characteristics determine attractive buttocks. They also found the balanced anatomic dimension of the maximal gluteal projection. RESULTS: On the basis of the information obtained, the defects of the gluteal region were classified into five types, resulting in surgical recommendations intended to achieve buttocks as close as possible to the standard of beauty, with the right volume and projection. CONCLUSIONS: The authors concluded that surgery for correction of the buttocks involves more than projection and volume. The surgeon must be familiar with the "signs" of beauty so an attempt can be made to recreate them. Most importantly, the surgeon should achieve buttocks with projection and volume. However, these must be in a balanced proportion with the rest of the body.

The fate of intramuscularly injected fat autografts: an experimental study in rabbits.

An experimental study was designed to assess the viability and revascularization of intramuscularly injected fat autografts. For the study, 18 rabbits were divided into two groups. In the first group, fat was injected intramuscularly (12 rabbits). Autologous fat was obtained from the inguinal area and subsequently injected into the thigh muscle. In the second group, physiologic saline was injected intramuscularly to determine the effects of cannulation and pressure on muscle tissue (6 rabbits). Fat autografts were performed on the right side of the animal, and the left side was used as the control. Scintigraphic imaging and histopathologic examination of the limbs were performed after injection of adipose tissue on days 15, 30, 45, 60, 90, and 120. On the technetium-99m ((99m)Tc) hexamethylpropylene amine oxime scintigraphy, whereas similar activity distribution was observed between the left and right thigh on days 15, 30, and 45, there was increased uptake at the right thigh on days 60, 90, and 120. This increased uptake indicates that there is viable fat tissue in this region. Histopathologic evaluation showed that microcysts resulting from degeneration of some adipocytes and inflammatory changes on day 15 additionally increased vascularity and fibrosis in some animals on day 30, as well as fibrosis, microcysties, and focal calcification areas in adipose tissue on day 45 and later. It was observed that adipose tissue survived in more than 50% of the graft area in all the animals. These findings show that fat autografts can survive in muscle tissue with less than 50% fibrotic change.

Benign symmetric lipomatosis (Madelung's disease): case reports and current management.

Benign symmetrical lipomatosis (BSL) is a rare disorder characterized by the presence of multiple, symmetric, nonencapsulated fat masses in the face, neck, and other areas. Typically, this entity has been related to the presence of three anterior bulges in the neck. The disorder was first described by Brodie in 1846. After that, Madelung in 1888 and Launois and Bensaude in 1898 characterized the disease. There are multiple synonyms for this disorder, such as Madelung's disease, Launois-Bensaude syndrome, and multiple symmetrical lipomatosis. Benign symmetric lipomatosis is usually described in adults from 30 to 60 years old, with an incidence of about 1 in 25,000 and a male-to-female ratio of 15:1 to 30:1. Most cases have no hereditary pattern. More than 90% of the patients have associated alcoholism. The etiology of benign symmetric lipomatosis remains unknown, but an abnormal lipogenesis induced by catecholamines has been observed. The transformation of BSL to a malignant tumor is extremely rare. In the current report, the authors describe two cases of benign symmetric lipomatosis treated in their department and a review of the literature.

Impact of large-volume liposuction on serum lipids in orientals: a pilot study.

Recent advances in liposuction techniques now make it possible to remove considerable amounts of subcutaneous adipose tissue. However, the metabolic consequences of this procedure are not well documented. The aim of this study was to identify the effects from the surgical removal of subcutaneous fat on the body weights and serum lipids of patients who have undergone large-volume liposuction. In this study, eleven consecutive patients with a minimum aspirate volume of 5,000 ml were evaluated, and their serum lipids were measured at a postoperative 2-month follow-up assessment. Tumescent fluid was infiltrated using the superwet technique. The liposuction device used was a Liposlim power-assisted liposuction system. The amount of solution infiltrated and the volume of aspirate were measured. Pre- and postoperative serum lipids, body weights, and body mass indices were compared. Statistical analysis was performed on lipid profile changes and aspirate volumes using Spearman's correlations. The average volumes of infiltrate and aspirate were 7,241 and 6,790 ml, respectively. Mean body weight decreased from 64.5 +/- 18.8 to 59.9 s +/- 17.8 kg (p < 0.01). The change in body weight per 1 l of aspirate volume was 0.67 +/- 0.10 kg/l. The mean body mass index dropped from 23.8 +/- 4.4 to 22.0 +/- 4.2 kg/m(2) (p < 0.01), and the mean total serum cholesterol levels from 168.2 +/- 23.6 to 162.9 +/- 26.5 mg/dl, an average of 3.2%. The mean low-density lipoprotein (LDL) decreased from 94.3 +/- 20.5 to 89.5 +/- 19.0 mg/dl, a 5.1% drop, and the mean high-density lipoprotein (HDL) decreased from 55.8 +/- 9.5 to 53.7 +/- 10.7 mg/dl, a 3,8% drop. The mean HDL/LDL proportion increased from 62.6 +/- 20.9% to 63.5 +/- 22.4%, averaging 1.4%. However, no significant correlation was found between the aspirated volume of fat and lipid profile change. In conclusion, over a 2-month period, large-volume liposuction reduced weight and total cholesterol level and increased the HDL/LDL ratio. The authors hope to discover whether the therapeutic impact of liposuction is long-lasting, and to determine whether it reduces the morbidity and mortality associated with obesity.

Cutis marmorata resemblance after liposuction.

Liposuction is a safe method for the treatment of lipodystrophy. It gives good results in relation to body contours, especially when the superficial and deep layers of the superficial fascia are aspirated. The authors present clinical cases of female patients who underwent liposuction of the abdomen, flanks, and back in which superficial and deep liposuction was used. In the immediate postoperative period, these patients presented a skin pattern of marbled appearance, involving rosy-purplish stains intermingled with other whitish stains on the skin in the areas subjected to surgery and resembling the cutis marmorata described in the literature. Even 1 year after the operation, the stains had not receded. The literature mentions cases of cutaneous necrosis provoked by a temperature increase induced by liposuction cannulas. This trauma said to be the determining factor for local lesions of the subdermal plexus. However, no cases involving lesions of this plexus attributable to mechanical trauma from cannulas are cited. According to several authors, it is important during superficial liposuction to maintain a strip about 1 cm thick under the deep dermis for the preservation of the arterial plexus of the skin. This would avoid the formation of a skin pattern resembling cutis marmorata.

Various surgical techniques for improving body contour.

Body contouring surgery is the most frequently performed aesthetic surgical procedure. Multiple and varied options exist for obtaining an adequate body contour, and most surgeries address the thoracoabdominal region. Because the success of a surgery depends greatly on the selection of the proper surgical procedure, this article presents an approach for selecting the best surgical option based on the characteristics of each patient. Considering this, surgeons approach a contour problem with two options: to modify the content or to modify the container. These options include five basic surgical procedures: pexia, dermolipectomy, liposuction, fat infiltration, and implant placement. Each patient requires a different technique and many need several procedures during the same surgical session to obtain the best results. Likewise, each procedure should be undertaken according to precise indications, depending on the aesthetic problem of the patient and the individual characteristics of the treated area. It is for this reason that the most important factors to be considered should be analyzed to determine the best surgical procedure and the combination of surgical procedures that will improve the thoracoabdominal contour for the same patient.

Use of a regional infusion pump to control postoperative pain after an abdominoplasty.

This study presents the clinical results for 20 patients who underwent abdominoplasty. A subset of these patients were given a pain relief system that provides continuous infusion of a nonnarcotic medication directly into the surgical wound to reduce postoperative pain. Whereas patients received a pain pump in addition to standard oral/intramuscular pain medication, 10 patients received only the standard oral and intramuscular postoperative pain medications. All 20 patients then were asked to complete an evaluation of their postoperative discomfort and pain. The findings show a significant reduction in postoperative pain with the use of the ambulatory pain pump. The simplicity of installing and running the pump and the benefits obtained, including early ambulation and less pain as well as reduced need and strength of narcotic medications lead the authors to believe that the implementation of this pain control technology soon will become widespread in their specialty. The study indicates that patients require less sedation and get out of bed sooner with this device, thereby reducing the incidence of deep venous thrombosis, pulmonary emboli, and narcotic-dependency.

Scientific basis for the use of hypotonic solutions with ultrasonic liposuction.

BACKGROUND: A number of plastic surgeons have advocated using hypotonic solution in ultrasound lipoplasty, theorizing that induced adipocyte swelling increases membrane susceptibility to ultrasonic disruption. Additionally, it has been theorized that potassium increases membrane permeability. This study aimed to determine the effect of solution osmolality on adipocyte diameter, the time course of hypotonic solution action, and the effect of potassium addition on adipocyte diameter. METHODS: Base solutions with three different osmolalities were prepared: normal saline (NS) (154 mOsm/l), 1/2NS (77 mOsm/l), and 1/4NS (38.5 mOsm/l). Each solution was modified to contain 0, 5, and 10 mEq/l of potassium and adjusted to starting osmolality. Adipocytes of six patients were suspended in the nine solutions, and diameters were determined at 0, 15, 30, and 45 min. Diameters were measured using imaging software (Kodak ID 3.6). RESULTS: At time 0, the average adipocyte diameter was 79 +/- 8 microm, and no difference was seen in any of the solutions. Cells in the NS group showed no significant increase in diameter over 45 min. The 1/2NS group achieved an 8% +/- 1.9% increase in diameter at 45 min (p < 0.05). The 1/4NS group showed an increase by 14% +/- 2.4% (p < 0.01) at 15 min, and 15% +/- 2.3% (p < 0.01) at 45 min. Potassium had no independent effect on cell diameter. CONCLUSIONS: Hypotonic solution can significantly increase human adipocyte diameter. The findings showed that 1/2NS had a significant effect within 15 min. Tumescent solutions with an osmolality of 1/4NS may be useful in facilitating ultrasonic lipoplasty.

Changing the metabolic profile by large-volume liposuction: a clinical study conducted with 123 obese women.

Adipose tissue is a metabolically active tissue. The hypertrophic fat cells of obese patients produce increased quantities of leptin and tumor necrosis factor-alpha (TNF-alpha) and are less sensitive to insulin. This study aimed to determine whether aspirating large amounts of these subcutaneous fat cells by large-volume liposuction (LVL), could change the metabolic profile in 123 obese women. All the patients had a main central body fat distribution (waist-hip ratio, 0.91+/-0.01) and a body mass index of 32.8 +/- 0.8 kg/m). They were studied for 90 days after LVL to determine their changes in insulin sensitivity, resting metabolic rate, serum adipocytokines, and inflammatory marker levels. During 3 months of follow-up evaluation, LVL resulted in a significantly improved insulin sensitivity, resting metabolic rate, serum adipocytokines, and inflammatory marker levels. Such parameters correlate with a decrease in fat mass and waist-hip ratio. Interestingly, no significant changes were seen between the first (21 days) and second (90 days) metabolic determinations after LVL. However, these findings, confirm other preliminary data published previously, and could change the actual role of LVL in the multidisciplinary treatment of obesity.

Refinements of vertical scar mammaplasty: circumvertical skin excision design with limited inferior pole subdermal undermining and liposculpture of the inframammary crease.

Vertical scar mammaplasty, first described by Lötsch in 1923 and Dartigues in 1924 for mastopexy, was extended later to breast reduction by Arié in 1957. It was otherwise lost to surgical history until Lassus began experimenting with it in 1964. It then was extended by Marchac and de Olarte, finally to be popularized by Lejour. Despite initial skepticism, vertical reduction mammaplasty is becoming increasingly popular in recent years because it best incorporates the two concepts of minimal scarring and a satisfactory breast shape. At the moment, vertical scar techniques seem to be more popular in Europe than in the United States. A recent survey, however, has demonstrated that even in the United States, it has surpassed the rate of inverted T-scar breast reductions. The technique, however, is not without major drawbacks, such as long vertical scars extending below the inframammary crease and excessive skin gathering and "dog-ear" at the lower end of the scar that may require long periods for resolution, causing extreme distress to patients and surgeons alike. Efforts are being made to minimize these complications and make the procedure more user-friendly either by modifying it or by replacing it with an alternative that retains the same advantages. Although conceptually opposed to the standard vertical design, the circumvertical modification probably is the most important maneuver for shortening vertical scars. Residual dog-ears often are excised, resulting in a short transverse scar (inverted T- or L-scar). The authors describe limited subdermal undermining of the skin at the inferior edge of the vertical incisions with liposculpture of the inframammary crease, avoiding scar extension altogether. Simplified circumvertical drawing that uses the familiar Wise pattern also is described.

A retrospective study on the use of a low-molecular-weight heparin for thromboembolism prophylaxis in large-volume liposuction and body contouring procedures.

This retrospective study was designed to evaluate the efficacy of low-molecular-weight heparin (enoxeparin) as a prophylaxis for venous thromboembolism and deep venous thrombosis (DVT) in the management of large-volume liposuction, added body-contouring procedures, or both. The author present an 18-month experience with the use of this therapy for 291 consecutive patients. All the patients fell into the categories of high risk and highest risk for the development of deep vein thrombosis, embolism, or both. Three patients experienced transient DVT-like symptoms and underwent a thorough workup by an independent highly specialized critical care medical team. The results were found ultimately to be inconclusive for DVT and pulmonary embolism. However, all the patients experienced a complete recovery. The results show a 0% incidence of DVT and pulmonary embolism among patients who received enoxeparin as prophylaxis. The medication did not precipitate major bleeding when administered 1 h after surgery. This study offers the first report that describes the use of enoxeparin in aesthetic surgery for high-risk patients. The authors feel the need to inform their colleagues of the benefits obtained over the past 18 months by incorporating this therapy in large-volume liposuction and extensive body-contouring procedures performed during the same operative session. This study was conducted by a highly experienced surgical team in a fully accredited outpatient facility with established protocols for handling these types of procedures on a daily basis. The authors are optimistic about the results, and the use of enoxeparin is now part of their postoperative regimen in high-risk aesthetic surgery cases.

Triple plication in miniabdominoplasty.

A novel method for plication of the abdominal fascia in miniabdominoplasty addresses abdominal laxity and improves the waistline. The design comprises a vertical plication of the rectus fascia from xiphoid to pubis and fusiform plication of the oblique fascias with limited undermining and scars, all in the setting of a miniabdominoplasty. The procedure was performed for 10 women undergoing surgery between January and December 2004. The technique resulted in improved tension of the entire abdomen, a decreased perimeter of the waist, and improved uniformity in the contour of the anterior and lateral view, avoiding the epigastric bulking generated when infraumbilical vertical plication is used alone. There were few minor and no major complications. At the follow-up assessment 6 months to 2 years after surgery, there was no loss of the improved muscle-aponeurotic tension or abdominal contour. Triple plication of the fascia provides a good method for improving both the waistline and abdominal laxity in the setting of a miniabdominoplasty.

Treatment with ultrasound-assisted liposuction of accessory axillary breast tissues.

Supernumerary nipples and breast tissue often are dismissed as cosmetic curiosities. These structures have the potential for pathologic degeneration and may be associated with significant congenital abnormalities. In a prospective comparison of 100 Native American women with 100 non-Native American women, these accessory organs were found much more commonly among Native American women. Careful attention should be given to thorough evaluation and long-term follow-up evaluation of any patient with this anomaly. This study investigated a patient who underwent surgical removal of her axillary breast tissue with ultrasound-assisted liposuction. The advantages of this method include a minimal incision scar from the liposuction cannula and the ability to detect residual axillary breast by ultrasound.

Magnetic resonance imaging assessment of gluteal fat grafts.

BACKGROUND: One goal of lipoplasty is to create a round and projected buttock contour. Despite multiple papers evaluating lipoinjection, controversies still remain. METHODS: This report describes a series of patients who underwent liposuction, gluteal lipoinjection, and evaluation with magnetic resonance imaging (MRI). From January 2003 to January 2004, the patients scheduled for contour surgery by the investigators were evaluated using MRI, photographic records, and gluteal circumference measurement 1 week before surgery, then 2 weeks and 3 months after the procedure. A statistical analysis was performed for 10 patients who received, on the average, a 350-ml injection of fat obtained during liposuction. RESULTS: Gluteus muscle volume increased, reaching a higher level 2 weeks after the injection than the level 3 months afterward (p < 0.001). The gluteal circumference, modified 2 weeks after surgery by about 1 to 3 cm, came back to previous values 3 months after the procedure (p < 0.05), a phenomena interpreted as reabsorption and resolution of the postoperative edema. There is no correlation between the gluteus muscle volume obtained by MRI and the gluteal circumference (p > 0.05). CONCLUSIONS: The findings led to the conclusion that enhancement of the gluteal contour after fat injection results from survival of the injected tissue 3 months after the surgery, which was objectively evaluated by MRI as having a calculated reabsorption rate of 24% to 36%.

Smokers: risks and complications in abdominal dermolipectomy.

Cigarette smoke has many detrimental effects on health, with consequences such as cardiovascular diseases, respiratory diseases, and tumors. In plastic surgery, these effects appear during the wound healing process. This retrospective study showed wound healing in 57 patients who had undergone abdominal dermolipectomy surgery. The patients were divided into two groups: smokers and nonsmokers. According to the results, smokers face a great complication risk for surgical wounds, which cause aesthetically more undesirable scars than observed in nonsmokers. The authors hypothesize that abstinence from smoking for 4 to 12 weeks before surgery would improve the quality of the scars.

Conservative management of local Mycobacterium chelonae infection after combined liposuction and lipofilling.

A case of Mycobacterium chelonae infection in the buttock after combined liposuction and lipoinjection is presented. The real possibility of contamination from operating room equipment was the potential etiologic factor of this infection. The clinical presentation of the disease was typical. The difficulty confirming the diagnosis was solved by specific culturing techniques. Successful treatment with limited debridement and irrigation combined with prolonged specific antibiotic therapy effected a long-term cure.
