Existe en la práctica diaria de los cirujanos plásticos una búsqueda continua de mejores alternativas técnicas para el tratamiento de las deformidades del contorno abdominal. La LADE (Lipoabdominoplastia con defi nición anatómica) da un paso más adelante de la técnica LAP tradicional. Esta técnica incorpora los principios de resaltar la defi nición de la musculatura abdominal, consiguiendo resultados más naturales y con menos estigmas de una intervención quirúrgica. Los resultados estéticos son mucho más armoniosos, con un verdadero aspecto abdominal rejuvenecido. Logramos reducir la morbilidad preservando los vasos sanguíneos perforantes y suspendiendo la fascia de Scarpa. Una correcta selección del paciente asociado a la estandarización de esta técnica hace que el procedimiento sea seguro y reproducible

There is a continuous search for better technical alternatives for the treatment of abdominal contour deformities in the practice of plastic surgeons. LADE ­ Lipoabdominoplasty with Anatomical Defi nition ­ is a step ahead of the traditional LAP technique. This technique incorporated the principles of highlighting the defi nition of the abdominal musculature, achieving more natural results with fewer reminders of a surgical intervention. The aesthetic results are much harmonious, with a true abdominal rejuvenated appearance. We can reduce morbidity by preservation of perforating blood vessels and suspension of Scarpa's fascia. The correct selection of the patient associated with the standardization of this technique makes the procedure safe and reproducible

A reinterpretation of human breast anatomy includes all the layers of the anterior body wall.

Mammary glands define mammals as a group, yet a comprehensive anatomical description of the mammary gland does not exist for almost any mammalian species. In humans, the anatomical and surgical literature provide conflicting and incomplete descriptions of the gross anatomy of the breast. We dissected 9 male and 15 female human body donors to clarify this gross anatomy. We found that, like other epidermally derived glands of the body, the mammary glandular tissue is constrained to a membrane-bound, central structure referred to as the corpus mammae in the surgical literature, and not dispersed throughout the breast as typically described in the anatomical literature. The major fasciae of the human anterior body wall, including the superficial fatty Camper's fascia and the deeper membranous Scarpa's fascia, both contribute to the structure of the breast. This anatomical arrangement suggests that, as the mammary gland invaginates posteriorly from the integument during embryological development, the mammary fat pad most likely derives from Camper's fascia, and growth of Scarpa's fascia around this fat pad forms the anterior and posterior lamellae of the breast pocket. Anteriorly, Scarpa's fascia becomes a double layer that creates the surface structure of the breast. Posteriorly, Scarpa's fascia forms a circummammary ligament that (1) stabilizes the breast against the thoracic wall and (2) is continuous with Scarpa's fascia on the rest of the anterior body wall. The suspensory ligaments of the breast represent the typical retinaculae cuti found consistently throughout the human body wall, and do not directly attach to the skin. Instead, these retinaculae attach to the anterior or posterior lamella of Scarpa's fascia.

Abdominoplasty after massive weight loss. Safety preservation fascia technique and clinical outcomes in a large single series-comparative study.

Introduction: Weight loss after bariatric surgery causes very important modifications to the patient's silhouette. Abdominal fat and skin excess reduction are associated with several complications. The most frequent are seroma and hematoma whereas major complications, such as pulmonary embolism, are less frequent. This study aimed to describe our technical procedure for abdominoplasty in patients with massive weight loss after bariatric surgery. Methods: In total, 196 patients were included. All patients who underwent abdominoplasty classic (group A) and abdominoplasty with the preservation and lift of Scarpa fascia (group B) and with umbilical transposition between May 2018 and May 2021 were included. Patients with concomitant correction of ventral hernia were excluded. Demographic and operative data were analyzed according to comorbidities and postoperative complications. Results: There were 160 (81.6%) women. The mean age was 43.6 years; the mean weight was 86.7 kg; and the mean BMI was 28.6 kg/m2. Five patients (2.5%) presented postoperative seroma. Four patients (2%) presented partial dehiscence/skin necrosis one of them requiring a revision. Finally, 26 patients presented a postoperative complication, with an overall incidence of 12.6%. The average postoperative hospital stay was 3.6. The rates of seroma were significantly higher in men, patients with a BMI > 30 kg/m2, and aged >50 years. Conclusion: Preserving Scarpa Fascia during surgical post-bariatric patient procedures reduces the seroma formation and the scar complication and reduces the tension of the inguinal-pubic region with correction of our deformation after weight loss. Improves reducing the drain and reducing seroma incidence suction and hospital stay.

Prevalence of Scarpa's ganglion enhancement on high-resolution MRI imaging.

BACKGROUND AND PURPOSE: The vestibular ganglion, or Scarpa's ganglion, is a cluster of afferent vestibular neurons within the internal auditory canal (IAC). There is minimal literature describing enhancement of this region on magnetic resonance imaging (MRI) and its correlation to clinical symptoms. Here, we sought to find the prevalence of enhancement at Scarpa's ganglion, and determine whether such enhancement correlates with demographics or clinical symptoms. MATERIALS AND METHODS: A retrospective review was performed of consecutive patients with an MRI of the IAC between 3/1/2021 and 5/20/2021. Two neuroradiologists independently reviewed for T1 and FLAIR enhancement of the Scarpa's ganglion on post-contrast fat-saturated T1 and post-contrast FLAIR images. Discrepancies were agreed upon by consensus. Clinical variables (hearing loss, vestibular symptoms, tinnitus, and MRI indication) were gathered from a retrospective chart review. RESULTS: Eighty-nine patients were included (51 female); the mean age was 58 (range 19-85). The most common MRI indication was hearing loss (n = 53). FLAIR enhancement was present on the right in 7 patients, on the left in 7 patients, and bilaterally in 6 patients. No enhancement was seen on post-contrast T1 images. There was no statistically significant correlation between consensus FLAIR on at least one side and age (p = .74), gender (p = .29), hearing loss (p = .32), hearing loss side (p = .39), type of hearing loss (p = .87), vestibular symptoms (p = .71), or tinnitus (p = .81). CONCLUSIONS: Enhancement is present in the minority of patients on post-contrast FLAIR images. If seen, it should be considered an uncommon but not unexpected finding with no clinical significance.

Analysis of Superficial Subcutaneous Fat Camper's and Scarpa's Fascia in a United States Cohort.

Together, the Camper's and Scarpa's fasciae form the superficial fat layer of the abdominal wall. Though they have clinical and surgical relevance, little is known about their role in body composition across diverse patient populations. This study aimed to determine the relationship between patient characteristics, including sex and body mass index, and the distribution of Camper's and Scarpa's fascial layers in the abdominal wall. A total of 458 patients' abdominal CT examinations were segmented via CoreSlicer 1.0 to determine the surface area of each patient's Camper's, Scarpa's, and visceral fascia layers. The reproducibility of segmentation was corroborated by an inter-rater analysis of segmented data for 20 randomly chosen patients divided between three study investigators. Pearson correlation and Student's t-test analyses were performed to characterize the relationship between fascia distribution and demographic factors. The ratios of Camper's fascia, both as a proportion of superficial fat (r = -0.44 and p < 0.0001) and as a proportion of total body fat (r = -0.34 and p < 0.0001), showed statistically significant negative correlations with BMI. In contrast, the ratios of Scarpa's fascia, both as a proportion of superficial fat (r = 0.44 and p < 0.0001) and as a proportion of total body fat (r = 0.41 and p < 0.0001), exhibited statistically significant positive correlations with BMI. Between sexes, the females had a higher ratio of Scarpa's facia to total body fat compared to the males (36.9% vs. 31% and p < 0.0001). The ICC values for the visceral fat, Scarpa fascia, and Camper fascia were 0.995, 0.991, and 0.995, respectively, which were all within the 'almost perfect' range (ICC = 0.81-1.00). These findings contribute novel insights by revealing that as BMI increases the proportion of Camper's fascia decreases, while the ratio of Scarpa's fascia increases. Such insights expand the scope of body composition studies, which typically focus solely on superficial and visceral fat ratios.

Postbariatric Abdominoplasty: A Comparative Study on Scarpa Fascia Preservation Versus Classical Technique.

BACKGROUND: Abdominoplasties performed with Scarpa Fascia preservation, improve recovery and reduce complications, particularly seroma. Bariatric patients who experience massive weight loss frequently seek body contouring procedures and represent a high-risk group. This study aimed to evaluate the effects of abdominoplasty with Scarpa Fascia preservation versus the classical technique in a bariatric population. METHODS: A retrospective observational cohort study was performed between March 2015 and March 2021 in 65 postbariatric patients who underwent a classic full abdominoplasty (group A, N = 25) or a similar procedure except for the preservation of Scarpa fascia (group B, N = 40). Total and daily drain output, time until drain removal, long drainers (≥ 6 days), length of hospital stay, emergency department visit, readmission to the hospital, reoperation, local and systemic complications were the outcomes evaluated. RESULTS: Group B had a 3-day reduction in time until drain removal (p < 0.001), a 62.6% reduction of total drain output (p < 0.001) and a 3-day reduction in the length of the hospital stay (p < 0.001). Long drainers (≥ 6 days) were highly reduced (from 56.0% in group A to 7.5% in group B) (p < 0.001). There was a lower incidence of liquid collections in group B, with a 66.7% reduction in seroma incidence. CONCLUSIONS: Abdominoplasty with Scarpa Fascia preservation improves recovery by reducing drain output, allowing earlier drain removal and reducing long periods with suction drains. It also reduces hospital stay and seroma incidence. This technique modifies the high-risk postbariatric patient in such a major way that he behaves like a nonbariatric.

Classic Versus Scarpa-sparing abdominoplasty: An infrared thermographic comparative analysis.

BACKGROUND: Scarpa fascia preservation during abdominoplasty has been shown to have several clinical advantages. The mechanisms behind its efficiency have been the subject of several studies. Three theories have been proposed, relating to mechanical factors, lymphatic preservation, and improved vascularization. This study aimed to further investigate the possible vascular impact of Scarpa fascia preservation by using a thermographic analysis. METHODS: A single-center prospective study was conducted, involving 12 female patients randomly and equally assigned to one of two surgical procedures: classic (Group A) and Scarpa-sparing abdominoplasty (Group B). Dynamic thermography was applied before and after surgery (one and six months), and two regions of interest (ROIs) were considered. The latter had the same location on every sample, and corresponded to areas where different surgical planes had been used. Static thermography was applied intraoperatively, and four ROIs were considered, located over Scarpa and over the deep fascia. The respective thermal data were analyzed. RESULTS: The general characteristics of both groups were identical. Preoperative thermography demonstrated no differences between groups. Intraoperative higher thermal gradients between lateral and medial ROIs were observed in Group B (P = 0.037, right side). Dynamic thermography at one month demonstrated a trend for better thermal recovery and better thermal symmetry (P = 0.035, 1-min mark) in Group B. No other differences were found. CONCLUSION: Dynamic thermography presented a better response when Scarpa fascia was preserved: stronger, faster, and more symmetric. Based on these results, improved vascularization may have a role in explaining the clinical efficiency of a Scarpa-sparing abdominoplasty.

Scarpa Fascia Preservation to Reduce Seroma Rate on Massive Weight Loss Patients Undergoing Abdominoplasty: A Comparative Study.

(1) Background: An increasing number of patients undergo bariatric surgery and seek body contouring surgery after massive weight loss (MWL). Abdominoplasty itself is associated with a high complication rate in these patients, particularly due to seroma formation. Scarpa fascia preservation (SFP) has been proven to be an efficient method of reducing seroma rates. We aimed to evaluate the possible benefits of SFP on massive weight loss patients comparatively. (2) Methods: This is a single-center retrospective comparative study encompassing 202 MWL patients operated between 2009 and 2019 at Turku University Hospital. Patients included in the study had a preoperative weight loss greater than 30 kg. Of them, 149 went through traditional abdominoplasty and 53 abdominoplasties with SFP. The primary outcome measure was seroma occurrence, while secondary outcomes included drainage amount, hospital stay, surgical site occurrence, and need for blood transfusion. (3) Results: The only statistically significant difference between groups on patients' demographics was the sex ratio, favoring females in the control group (43:10, 81% vs. 130:19, 87%, p = 0.018). SFP significantly reduced seroma occurrence (9.4% vs. 26.2%, p = 0.011) and decreased mean drainage duration (3.7 ± 2.4 vs. 5.3 ± 3.2 days, p = 0.025). There was a trend towards lower drainage output (214.1 ± 162.2 mL vs. 341.9 ± 480.5 mL, p = 0.060) and fewer postoperative days on ward in the SFP group. Other complication incidences did not differ between the groups. The multivariable analysis did not show any significant factor for seroma formation or surgical site occurrence. (4) Conclusions: Preserving Scarpa fascia on MWL patients may result in decreased seroma occurrence and a shorter time to drain removal.

[Coverage of an infected Deep femoral arteria vascular graft bypass by pediculated chimeric antero- lateral thigh flap associated with a vastus lateral muscle]. / Couverture d'un pontage par allogreffe de l'artère fémorale profonde par un lambeau pédiculé chimérique antérolatéral de cuisse associé au muscle vaste latéral.

Scarpa triangle defects with exposure of femoral bypass are challenging to treat. The authors present the case of a 46 years-old male with a groin defect of 10×18cm with an exposure on 5cm of an allograft of the deep femoral artery. Bypass was performed in emergency because of a limb ischemia with deep femoral artery thrombosis and aneurysm of the superficial femoral artery. The reconstructive surgery may propose a large musculo-cutaneous flap to fill the dead spaces surrounding the infected bypass, the flap should be vascularized by the deep femoral arteria, could not be the rectus abdominals flap because of the precedent abdominal incision. The homolateral pediculated ALT-flap with vastus lateral component appeared to be a good solution because of its versatility and the low morbidity of the donor site.

Abdominoplasty with Scarpa Fascia Preservation: A Systematic Review and Meta-analysis.

BACKGROUND: Scarpa fascia preservation has been proposed to minimize complications associated with conventional abdominoplasty, but its efficacy is unclear. The purpose of this article is to determine the influence of preserving scarpa fascia on reducing postabdominoplasty complications. METHODS: A comprehensive search of Medline Ovid, PubMed, Web of Science, and the Cochrane CENTRAL databases was conducted from the inception till June 2021. Eligible studies were prospective controlled studies investigating postoperative complications after scarpa fascia preservation following abdominoplasty. Stata 15.1 software was used for the meta-analysis. RESULTS: The meta-analysis included seven studies with 682 abdominoplasty patients. Abdominoplasty with scarpa fascia preservation could significantly reduce incidence of seroma (OR = - 1.34, 95% CI = - 2.09 - - 0.59, P < 0.05), length of hospital stay (SMD = - 1.65; 95% CI = - 3.50-0.20; P = 0.08), time to drain removal (SMD = - 3.64; 95% CI = - 5.76 - - 1.52; P < 0.05), and total drain output (SMD = - 401.60; 95% CI = - 593.75 - - 209.44; P < 0.05) compared with that of conventional abdominoplasty. However, it failed to achieve a statistically significant reduction in hematoma (OR=- 1.30, 95% CI = - 2.79-0.18, P = 0.08), infection (OR = - 1.03; 95% CI = - 2.17-0.12; P = 0.08), skin necrosis (OR = 0.63; 95% CI = - 1.20-2.45; P = 0.50), and wound dehiscence (OR = 0.28; 95% CI = - 0.28-0.83; P = 0.33). The seroma incidence rate was lower when a scalpel was utilized for dissection rather than electrocautery (3% (95% CI = 1-7%) versus 11% (95% CI = 5-18%)). CONCLUSIONS: Preservation of scarpa fascia during abdominoplasty might reduce the likelihood of postoperative seroma, length of hospital stay, time to drain removal, and total drain output. However, it did not significantly affect the incidence of hematoma, infection, skin necrosis, and wound dehiscence.
