Traditional abdominoplasty

Indications of Oblique Flankplasty

The oblique flankplasty is an important alternative in truncal body contouring surgery. Because of the proximity and direction of the incision, it is effective in narrowing the waist and addressing the challenging flank area. There are pros and cons to the technique, specifically when compared with a lower body lift, and these should be carefully considered for each patient.

Shear Wave Elastography for Assessment of Changes in Abdominal Soft Tissues after Lipoabdominoplasty

BACKGROUND

The changes in the elasticity of the abdominal skin, subcutaneous tissues and muscles after lipoabdominoplasty are still unknown. The aim of this study was to provide an objective assessment of tissue elasticity after lipoabdominoplasty using ultrasound elastography.

METHODS

A total of 21 female patients (31-41 years old) who underwent lipoabdominoplasty from Oct 2019 to Mar 2022 were included in this retrospective study. The elastography values of the skin, subcutaneous tissues and abdominal muscles were obtained with the ultrasound shear wave elasticity imaging system pre-operation (Pre) and 6 months post-operation (Post) at four different points.

RESULTS

Twenty-one female patients were included. The elasticity of the abdominal skin, subcutaneous tissues, rectus abdominis and external oblique abdominis significantly increased at 6 months post-operation. The improvements in abdominal soft tissue elasticity were not uniform across the examined points.

CONCLUSIONS

Significant changes in the elasticity of the abdominal skin, subcutaneous tissues and muscles were observed after lipoabdominoplasty. Ultrasound elastographic assessment was objective and feasible for evaluating the effect of lipoabdominoplasty on abdominal soft tissue.

Retrospective Analysis of Predictive Factors for Complications in Abdominoplasty in Massive Weight Loss Patients

INTRODUCTION

Ex-obese patients present with redundancy of abdominal skin and soft tissue due to massive weight loss (MWL). The plastic surgeon can restore the body shape through body contouring procedures. Hence the need to adequately direct patients to body contouring by identifying suitable candidates exists. Our work aims to retrospectively analyze the abdominoplasty complications in our case series to identify associated risk factors and evaluate the effect of combined procedures on abdominoplasty outcomes.

MATERIALS AND METHODS

We retrospectively investigated predictive factors of abdominoplasty procedure complications on 213 MWL patients who received abdominoplasty with and without rectus sheath plication, abdominal liposuction, and other body contouring procedures. We identified risk and protective factors with univariate and multivariate regression analysis. Furthermore, we assessed the impact of additional procedures on the complication rates.

RESULTS

The overall complication rate was 49.8% (26.8% minor complications; 23% major complications). The delayed wound healing rate was 27.7%, and the revision surgery rate was 25.8% (14.7% early revision; 14.2% late revision). These results were compared with literature reports. Several negative predictors emerged as non-modifiable (advanced age, diabetes mellitus, surgical mode of weight loss) or modifiable (preoperative obesity and body mass index (BMI); active smoking; preoperative anemia; use of fibrin glue or quilting sutures). Performing rectus sheath plication improved most of the outcomes. Liposuction of hypochondriac regions and flanks led to increased safety and reduced the risk of surgical dehiscence and delayed wound healing, in contrast to epimesogastric liposuction. The other combined body contouring procedures did not worsen the outcomes, except for poor scarring.

CONCLUSION

Our findings encourage us to continue associating rectus sheath plication, liposuction, and other body contouring surgeries with abdominoplasty. We emphasize the importance of proper patient selection, particularly with regard to anemia, before body contouring surgery in the interests of offering safe surgery and satisfactory results. Further studies are needed to investigate how the optimal BMI cut-off and abstinence from smoking (in terms of time) before surgery reduce postoperative complications.

Two-stage Radiofrequency-assisted Lipoabdominoplasty

Decades of lipoabdominoplasty safety, reliability, and efficacy have permitted more aggressive contouring of the abdominoplasty flap without increased risk for wound healing complications. However, the recent introduction of unrestricted liposuction of all vascular zones and high-definition liposculpting continue to challenge the vascularity of the abdominoplasty flap, particularly in high-risk patients. The present study reviews the authors' approach to abdominal lipodystrophy, and introduces a technique which maximizes fat extraction and skin excision while reducing risk of complication (two-stage radiofrequency-assisted liposuction and abdominoplasty).

TULUA Male High-Definition Abdominoplasty

BACKGROUND

Abdominoplasty is a surgical technique for body contouring that has been shown to improve the patient's quality of life. It has become more common among male patients, so clear differences between procedures for men and women have to be stated. The authors present their experience with high-definition lipoabdominoplasty with transverse plication in men.

METHODS

Records of male patients undergoing transverse plication full abdominoplasty in addition to high-definition liposculpture were analyzed. A total of 24 consecutive cases were found between January of 2017 and June of 2019. Patient ages ranged from 24 to 60 years. Patients aged 18 years or younger were excluded. Body mass index ranged from 25 to 33 kg/m2. Photographic records were taken before and during follow-up at 2 days and 1, 3, 6, and 12 months after surgery.

RESULTS

Male TULUA (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar) with high-definition lipoabdominoplasty was successfully achieved in 24 cases. No major complications were reported. Six minor complications were reported (25 percent). Rectus abdominis diastases are less common in men compared to women, as pregnancy is the most determining factor in its development. Fat distribution is also a key difference when performing lipoabdominoplasty for the male or the female patient. The authors recommend a transverse plication of the abdominal wall, instead of a vertical one, as flap viability is preserved and enhanced muscular definition can be accomplished.

CONCLUSIONS

Combining transverse plication with high-definition lipoabdominoplasty (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar plus high-definition lipoabdominoplasty) is a safe and reproducible technique for the male patient. It offers higher aesthetic results in line with modern beauty ideals.

The reverse lip design: a design for safe and effective abdominoplasty

Conventional abdominoplasty includes the removal of an ellipse-shaped section of abdominal tissue between the umbilicus and mons pubis. However, this method can result in tension of the undermined flap, especially in the midline. To address this problem, we present reverse lip design as a modified method that also has aesthetic advantages. The reverse lip design entails a longer lower flap edge while preserving the triangular tissue in the vascularly stable pubis area. These markings create an image of a reverse lip shape with a cleft at the bottom of the lower markings. After typical lipoabdominoplasty is performed, redundant waist tissues can easily be pulled inward and downward. The reverse lip design abdominoplasty demonstrated no complications and required no further revisions after the procedure. Patients were generally satisfied with the aesthetic improvements in their body shape. They were also able to return to their routine activities approximately 1 week after the operation while wearing a supporting undergarment. This modified abdominoplasty using the reverse lip design reduces low midline tension of the undermined abdominal flap while enhancing body aesthetics with a slimmer waistline, leading to higher patient satisfaction.

Corset Autodermis External Obliqueplasty Reinforcement of Rectus Diastasis and Umbilical Hernia Repairs during Abdominoplasty

SUMMARY

Abdominoplasty is among the most commonly performed aesthetic operations and is frequently combined with rectus abdominis musculoaponeurotic plication of rectus diastasis and repair of umbilical and ventral hernias. The authors present a spare parts technique to assist in reinforcement of both rectus diastasis plication and hernia repair during abdominoplasty operations using an autodermis onlay reinforcement graft. The graft is harvested from the excess abdominal pannus normally discarded during abdominoplasty and is inset on tension between the bilateral semilunar lines and plicated along a concave "corset" contour. This reduces distracting forces on the hernia and diastasis repairs and further augments abdominal contour. This technique has been performed for 8 years on 82 low-surgical-risk patients, without any noted increase in complications. The corset autodermis external obliqueplasty is a spare parts technique that may reduce recurrence of rectus diastasis and abdominal hernias repaired at the time of abdominoplasty and is an alternative strategy to mesh placement in this risk-averse aesthetic surgery population.

Abdominoplasty: My Preferred Techniques

BACKGROUND

Abdominoplasty has been evolving since the 1960s with many technical innovations throughout the years. It has become one of the most frequent and common procedures done in aesthetic plastic surgery, with the ultimate goal of not only to remove the excess tissue in the abdominal area but also to achieve an aesthetic trunk silhouette.

OBJECTIVE

The prime objective of this article was to describe our preferred approach for a full cosmetic abdominoplasty.

METHODS

We summarized all the key technical aspects from our shared surgical approach for abdominoplasty. The article describes collective experiences from authors performing the surgery in South America, North America, and Asia.

RESULTS

The key technical aspects identified were conservative muscle plication, customized excess tissue resection, and ultrasound-assisted liposuction to improve definition in the abdominal lines and body curves, combined with lipofilling. The aesthetic results are presented.

CONCLUSIONS

Abdominoplasty should be customized to every patient's anatomy and desired cosmetic outcome, taking into consideration all the anatomical areas surrounding the abdominal wall.

Outcome of Body-Contouring Procedures After Massive Weight Loss

BACKGROUND

With the increased popularity of bariatric surgery, the demand for body-contouring procedures is growing. Associated with these procedures are a number of complications due to different risk factors and patients' characteristics. The aim of this study was to assess the outcome of body-contouring procedures and correlate it to possible risk factors.

METHODS

The study included a collective of 112 patients who underwent 157 body-contouring procedures. Patients' characteristics, risk factors, and complications have been recorded. Three groups were formed based on the type of surgical procedure to perform correlations of BMI, weight of resected tissue, and length of hospital stay using Spearman's rank test. Correlations between patients' risk factors and complication occurrence were analyzed with Fisher's exact test.

RESULTS

The most common procedure patients underwent was the classic abdominoplasty (n = 53). A significant correlation was found between preoperative BMI and weight of resected tissue in abdominoplasties (rho = 0.69), Fleur-de-Lis abdominoplasties (rho = 0.64), and body lifts (rho = 0.60). There was a significant correlation between weight of resected tissue and length of hospital stay (rho = 0.53) and preoperative BMI and length of hospital stay (rho = 0.4) as well. There was no significant correlation between patients' comorbidities or smoking status and the postoperative complication rate. The mean weight of resected tissue was higher in patients with than without complications requiring surgical revision.

CONCLUSIONS

The relevance of risk factors commonly believed to have an influence on postoperative complications should be revised. The weight of resected tissue has an influence on complication.

Hip Asymmetry: Implications in Body Contouring Surgery

BACKGROUND

Asymmetry of the hips and its implication in body contouring procedures has not yet been reported. Hip asymmetry is common in the general population and may account for uneven abdominoplasty scar and the apparent discrepancies in volume following liposuction of the hips and flanks. The goal of this study was to determine the presence of hip asymmetry in women presenting for abdominal contouring surgery.

METHODS

Analysis of preoperative photographs of 100 female patients was performed by three independent plastic surgeons. They were asked to evaluate for hip asymmetry and, when present, determine which side was higher. Adobe Photoshop was also used to objectively measure hip asymmetry. Patients were women with no known history of hip abnormalities; age ranged from 17 to 64 years and the body mass index ranged from 16 to 47 kg/m(2).

RESULTS

All three plastic surgeon reviewers found that the majority of patients had hip asymmetry, with raters 1, 2, and 3 documenting discrepancies in hip height in 88, 60, and 76 percent of patients, respectively. The interrater reliability was 0.713. Chi-square statistical analysis suggested that the raters were not statistically different from one another (p = 0.086). The objective analysis found asymmetry in 82 percent of patients.

CONCLUSIONS

The results showed that the majority of patients who present for abdominal contouring surgery have asymmetric hips. Patients are usually unaware of the unevenness of their own hips; however, they often notice postoperative discrepancies in scar height after abdominoplasty or volume differences after liposuction.

[Research progress of abdominoplasty]

Objective

To summarize the research progress of abdominoplasty.

Methods

The literature related to abdominoplasty in recent years was reviewed and the evolution of this surgical method and related surgical techniques were summarized.

Results

By removing excess skin adipose tissue from abdominal wall and strengthening loosening muscle fascia system, the abdominal wall contour can be improved by abdominoplasty. With the development of liposuction, selective flaps undermining, progressive tension sutures, and Scarpa fascia retention, the trauma and complications of abdominoplasty are significantly reduced, and better aesthetic result is achieved.

Conclusion

At present, the incidence of abdominoplasty complication is still the highest among cosmetic surgeries, and further exploration is needed to reduce complications and improve aesthetic effects.

Histological and biochemical study of the superficial abdominal fascia and its implication in obesity

The advancement of liposculpturing and fascial flaps in reconstructive surgery has renewed interest in the superficial fascia of abdomen. Its histological and biochemical composition may play a vital role in maintaining strength and elasticity of the fascia. Hence, study of abdominal fascia for the elastic, collagen, and hydroxyproline contents is desirable to understand asymmetrical bulges and skin folds and in improving surgical treatment of obesity. Samples of superficial fascia were collected from of upper and lower abdomen from 21 fresh cadavers (15 males and 6 females). Samples were stained using Verhoeff–Van Gieson stain. Digital images of superficial fascia were analyzed using TissueQuant software. The samples were also subjected to hydroxyproline estimation. The superficial fascia was formed by loosely packed collagen fibers mixed with abundant elastic fibers and adipose tissue. Elastic contents and collagen contents of superficial fascia were significantly more in the upper abdomen than that in the lower abdomen in males. Hydroxyproline content of superficial fascia of upper abdomen was significantly more than that of lower abdomen in both males and females. The elastic, collagen and hydroxyproline contents of superficial fascia of upper abdomen were higher compared to the lower abdomen. This may be a reason for asymmetric bulging over abdomen and more sagging fold of skin in the lower abdomen than in the upper abdomen. This study may therefore be helpful in finding new ways to manage obesity and other body contour deformities.

Redefining abdominal anatomy: 10 key elements for restoring form in abdominoplasty

While traditional abdominoplasty methods can successfully achieve the objective of restoring a flat appearance, the results can be artificially board-like, lacking the subtle anatomical features of a three-dimensional abdomen, thus creating the potential for patient dissatisfaction. While often difficult to articulate, patient criticism is almost always distilled to the ubiquitous concern that the surgical abdomen lacks the natural features of an authentic, youthful abdomen. In an effort to provide a more anatomically accurate outcome and improve patient satisfaction, I have made a series of technical modifications to the abdominoplasty that I now perform. Ten key technical refinements, including a modified "Anatomy Defining" Progressive Tension Suture technique, were successively incorporated in 177 patients during the first 5 years of 2000-2014. All have been applied consistently in 961 abdominoplasty procedures during the subsequent 10 years, often accompanied by liposuction of adjacent lateral (non-abdominal) areas to ensure harmonious proportion. This series of refinements adds precision and detail by redefining the native anatomical nuances of the abdomen, an aesthetic objective that has been consistently achieved in BMI ranges between 20 and 35. Overall satisfaction with results was high (94%). The 10 elements described are safe, effective, and lasting.

Comprehensive Liposuction and Complete Abdominoplasty: A Review of 644 Consecutive Cases and Analysis of Complications

The standard of care in abdominal recontouring is complete abdominoplasty. Originally described in 1899 as abdominal lipectomy, the evolution of the procedure has involved rectus plication and application of tension in an effort to improve cosmetic benefits. Resistance to combined lipoaspiration has been fueled by fears of increased complications such as increased rates of ischemia, devascularization, dehiscence, seromas, and higher revision rates. A paucity of evidence supported these fears. We retrospectively reviewed 644 consecutive abdominoplasties performed by one surgeon (E.J.N.) in a facility accredited by the American Association for Ambulatory Healthcare. All patients were American Society of Anesthesiologists (ASA) 1–3.

The incidence and management of secondary abdominoplasty and secondary abdominal contour surgery

BACKGROUND

Limited data exist in the literature regarding the general incidence of secondary abdominal contour procedures and secondary abdominoplasty (excluding revisions) or specific recommendations for surgical management of these patients.

METHODS

The authors performed a retrospective chart review of 562 patients who underwent abdominal contouring procedures (liposuction and/or modified or full abdominoplasty) performed by a single surgeon (A.M.) from January of 2004 until October of 2012. Nonsurgical primary cases, secondary surgery that was revisional in nature, and massive weight loss patients were excluded.

RESULTS

Seventy-three patients (13.0 percent) underwent secondary abdominal contouring procedures. Forty-six of 73 patients had charts available to be examined in greater detail. Thirty-four of these patients underwent secondary liposuction, whereas 12 of these patients had secondary full abdominoplasty procedures. Secondary operations occurred an average of 4.98 years after the primary procedure (range, 6 months to 15 years). Patients underwent secondary liposuction (n = 34) on average 3.16 years after their initial procedure, significantly sooner than patients who underwent secondary abdominoplasty (n = 12) 8.35 years after their initial procedure (p = 0.002). Patients with a body mass index less than 25 kg/m2 (n = 26) had both secondary liposuction (n = 16) and secondary abdominoplasty (n = 10), whereas all patients who had a body mass index of 25 kg/m2 or greater (n = 20) underwent only secondary liposuction.

CONCLUSIONS

True secondary abdominal contouring procedures represented 13.0 percent of all abdominal contouring procedures. The most common indication for a secondary procedure was an umbilical-site closure scar. Specific recommendations for surgical management of five common scenarios for secondary abdominal procedures are discussed.

Outpatient lipoabdominoplasty: review of the literature and practical considerations for safe practice

BACKGROUND

Lipoabdominoplasty, popularized by Saldanha et al in 2001, is a powerful technique to contour the abdomen and flanks. It has not gained widespread use as concerns exist about increased complications related to wound healing and thromboembolism.

OBJECTIVES

The authors review the existing literature on lipoabdominoplasty and discuss their experiences with the technique in a retrospective case series.

METHODS

A literature search of PubMed/MEDLINE using the search terms lipoabdominoplasty and abdominoplasty was performed by 2 independent investigators. The charts of 85 consecutive patients who underwent lipoabdominoplasty between February 2007 and July 2012 were reviewed.

RESULTS

A combined 1316 lipoabdominoplasty patients had results reported in the literature. Of these patients, 21 of 1316 (1.6%) developed seroma, 5 of 1032 (0.5%) experienced hematoma, 6 of 1032 (0.6%) experienced venous thromboembolism, and 3 of 1032 (0.3%) developed pulmonary embolism. In our case series, all patients were women with an average age of 48 years (range, 27-70 years), average body mass index of 25.2 (17.7-35.5), average follow-up of 8 months (range, 1-54 months), average lipoaspirate of 1605 mL (range, 150-5350 mL), and average weight of resected tissue of 1039 g (range, 128-4838 g). The average operative time was 225 minutes (range, 88-435 minutes), and average time in recovery prior to discharge was 124 minutes (range, 33-270 minutes). Seroma occurred in 20 of 85 patients, 1 patient developed deep venous thrombosis (DVT), 1 patient developed cellulitis, and 1 patient developed an abscess.

CONCLUSION

Lipoabdominoplasty is a safe and effective procedure in appropriately selected patients. Performing the procedure in an outpatient setting requires attention to multiple factors in the perioperative period to ensure safe patient outcomes. Larger prospective studies should be performed to evaluate best practices regarding rare complications such as DVT or pulmonary embolism.

Layers of the abdominal wall: anatomical investigation of subcutaneous tissue and superficial fascia

INTRODUCTION

In recent times new surgical approaches have been developed, in which subcutaneous tissue is the primary object, such as flaps and fat removal techniques, but different descriptions and abundance of terminology persist in Literature about this tissue.

AIM AND METHODS

In order to investigate the structure of abdominal subcutaneous tissue, macroscopic and microscopic analyses of its layers were performed in 10 fresh cadavers. Results were compared with in vivo CT images of the abdomen of 10 subjects.

RESULTS

The subcutaneous tissue of the abdomen comprises three layers: a superficial adipose layer (SAT), a membranous layer, and a deep adipose layer (DAT). The SAT presented fibrous septa that defined polygonal-oval lobes of fat cells with a mean circularity factor of 0.856 ± 0.113. The membranous layer is a continuous fibrous membrane rich in elastic fibers with a mean thickness of 847.4 ± 295 μm. In the DAT the fibrous septa were predominantly obliquely-horizontally oriented, defining large, flat, polygonal lobes of fat cells (circularity factor: mean 0.473 ± 0.07). The CT scans confirm these findings, showing a variation of the thickness of the SAT, DAT and membranous layer according with the subjects and with the regions.

DISCUSSION

The distinction of SAT and DAT and their anatomic differences are key elements in modern approaches to liposuction. The membranous layer appears to be also a dissection plane which merits further attention. According with the revision of Literature, the Authors propose that the term "superficial fascia" should only be used as a synonym for the membranous layer.
