ABSTRACT

OBJECTIVE: The primary objective of this study was to determine the long-term satisfaction levels of women who have undergone breast augmentation and augmentation mastopexy procedures, while identifying the factors influencing patient satisfaction. METHODS: A self-reported retrospective case study design was used to collect data from women with breast implants. The study employed a survey that included demographic information, preoperative diagnosis, implant details, and patient-reported outcomes measured using the Breast-Q Instrument, which evaluates satisfaction with breasts, self-esteem, sexual well-being, and physical symptoms. Statistical analyses were conducted to identify correlations and differences in outcomes between the different variables. RESULTS: The survey was completed by 1022 women from 19 countries, with Chile, Mexico, and Colombia being the most represented. Augmentation was performed on 72.2% of the patients, while 27.7% underwent augmentation mastopexy. Patient satisfaction with breast size and shape varied significantly between the two procedures, with patients undergoing augmentation mastopexy showing less satisfaction. In addition, patients who were unaware of their implant shape or placement reported lower satisfaction scores. The study also found that patient satisfaction decreased over time in the augmentation mastopexy cases and that patients with high body mass index had lower satisfaction. CONCLUSION: Augmentation mastopexy in patients with breast ptosis yields lower satisfaction than augmentation alone. Dissatisfaction escalates with overweight/obesity (BMI), post-surgery time, and misinformation. Implant pocket (pre-vs. subpectoral), shape (round vs. anatomical), and size did not impact satisfaction.

ABSTRACT

This article explores the importance of understanding the tridimensional artistic anatomy of the back, pelvis, and thighs in gluteal surgery. It emphasizes the need for plastic surgeons to have a comprehensive knowledge of these anatomic structures to achieve successful outcomes. The authors highlight the significance of ethnic differences in determining ideal aesthetic results and stress the importance of considering and respecting these variations. Individualization of treatment is a key principle in gluteal surgery, as each patient has unique preferences and needs. Effective communication and collaboration between the surgeon and the patient are crucial in determining desired aesthetic goals and achieving satisfactory outcomes.

ABSTRACT

OBJECTIVES: To describe characteristics of women with aesthetically ideal buttocks and differentiate them from women with normal buttocks. METHODS: Case-control study comparing anatomy of women with ideal buttocks (buttocks models) to women with normal buttocks using magnetic resonance images, anthropometric measurements and photography. RESULTS: Comparing to normal women, buttocks models have a narrower waist, narrower iliac crest, wider C point, wider hips and bigger and thicker gluteus maximus muscle (GMM). A bigger GMM adds more projection to the C point, point of maximum projection in the lateral view is 2.7 cm higher than the pubic bone. The amount of subcutaneous fat was equal in models and controls. CONCLUSIONS: Our study provides new knowledge regarding the tridimensional aspects of the beauty of the buttocks area. A beautiful buttock is a conjunction of adequate bony shape, muscle development, subcutaneous fat layer, and tight skin. Comparing to normal women, buttocks models have a narrower waist, narrower iliac crest, wider C point, wider hips and bigger and thicker Gluteus Maximus Muscle. Accurate understanding of the aesthetic goals in a given patient can guide surgical technique. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

ABSTRACT

BACKGROUND: An informed consent is mandatory to obtain any clinical audiovisual material from patients. Although there are some documents created for this purpose, there are some barriers for their application, such as the context in which they were created, the language and download availability. AIM: To create a proposal for an informed consent form (ICF) for the capture and different uses for audiovisual material from patients. MATERIAL AND METHODS: A bibliographic search was carried out to obtain different ICFs in Spanish and English, which were subjected to a process of translation, counter-translation and fragmentation. Subsequently, a panel of experts was formed by members of the Chilean Society of Plastic Surgery with extensive experience in social networks. Delphi methodology was applied to reach a consensus about the definitive content of the ICF based on the previously selected fragments. RESULTS: ICFs available for download were identified. The panel was made up of seven Plastic Surgeons and two Delphi rounds were carried out through electronic surveys. At the end of the process, an ICF proposal was obtained for therapeutic, academic or scientific purposes and another for dissemination or education in the mass media. CONCLUSIONS: The proposed ICFs were liberated for their use among health care professionals in Chile, who could use them, provided that they are approved by the local healthcare ethics committees.

ABSTRACT

BACKGROUND: TULUA (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar) is the acronym for a radically different lipoabdominoplasty, intended to add simplicity, improve vascular safety, and attain good results. Modifications are unrestricted liposuction, no flap detachment, massive transverse infraumbilical plication, umbilicus amputation, neoumbilicoplasty, diminished tension wound closure, and low transverse scar settlement. The objectives of this article are to describe the technique and analyze a multicenter experience. METHODS: Sixty-eight plastic surgeons from 10 countries provided data for a retrospective review of 845 patients. Aesthetic results were scored by each surgeon using the Salles scale and analyzed in combination with complications to identify associations between patient and surgery characteristics. RESULTS: Of the patients, 95.5 percent were female, 19.7 percent were obese, 35.6 percent had prior scars, 10.4 percent had undergone previous abdominoplasty, 6.5 percent were postbariatric, and 6.6 percent were smokers. One patient had a kidney transplant, and 16.5 percent had comorbidities. Surgery characteristics varied widely, being on average as follows: lipoaspirate, 2967 ml; resection, 1388 g; and surgical time, 3.9 hours; 46.5 percent were not hospitalized. Averaged results were 8.68 of 10 points, besides adequate positioning and proportion of scar and umbilicus, without epigastric compensatory bulging (4.97 of 6 points). Overall complications were 16.2 percent, mostly seroma (8.8 percent); vascular-related complications (i.e., necrosis, wound dehiscence, and infection) constituted 2.7 percent. There were no fatalities. The logistic regression model demonstrated that smoking and obesity duplicate the risk of complications; if age older than 60 years is added, the risk of complication increases seven to nine times. Reported indications were multiple; however, pathologic diastasis was excluded. CONCLUSION: TULUA lipoabdominoplasty is a new reproducible procedure with good quantified results and an acceptable complication rate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

ABSTRACT

High-definition (HD) liposuction has allowed surgeons to sculpt the abdomen, enhancing abdominal etching. To create a more athletic abdomen, fat grafting has been used subcutaneously, and rectus abdominis fat grafting has been performed in patients undergoing lipoabdominoplasty. With the objective of increasing muscle volume to obtain a natural-looking abdomen in patients who are not suitable for abdominoplasty, we propose the use of ultrasound-guided rectus abdominis fat grafting (UGRAFT) in association with HD liposuction. PATIENTS: A prospective study with 10 consecutive patients undergoing UGRAFT was conducted. After HD liposuction, UGRAFT was performed from an incision in the umbilical region, using a blunt 2.5-mm cannula assisted by ultrasound. Fat injection was done closer to the anterior rectus sheath in the lower and middle muscle bellies. RESULTS: UGRAFT was performed in 10 patients. The mean age was 34.8 years (range, 24-51 years). The mean body mass index was 23.83 kg/m2 (range, 20.58-28.39 kg/m2). The mean volume of fat injected per "pack" was 34 cm3 (range, 20-40 cm3). UGRAFT added a mean time of 20 minutes (range, 15-30 minutes) to HD liposuction. Comparing the rectus abdominis muscle thickness pre-UGRAFT and post-UGRAFT, average muscle thickness increase was 5.1 mm (55.7% ± 37%), with P < 0.0001. CONCLUSION: UGRAFT showed to be helpful for obtaining muscle expansion and a more natural abdominal contour, avoiding that unnatural appearance that HD liposuction may provide in patients who gain weight or have skin laxity.

ABSTRACT

PURPOSE: This study aimed to compare the effects of ketamine and ketamine associated with magnesium on opioid consumption and pain scores in patients undergoing abdominoplasty and/or liposuction compared to standard treatment. PATIENTS AND METHODS: A total of 63 patients were included and randomized as follows: 21 patients in the Control group, 20 patients in the Ketamine group (Ket), and 22 patients in the Ketamine-magnesium group (KetMag). The KetMag group received an IV bolus of 0.3 mg/kg of ketamine and 50 mg/kg magnesium, followed by continuous infusion of ketamine (0.15 mg/kg/h) and magnesium (10 mg/kg/h) until extubation. The Ket group received the same bolus and infusion of ketamine, together with a bolus and continuous infusion of placebo instead of magnesium. The Control group received saline instead of ketamine and magnesium. The groups were compared in morphine consumption during the first 12h, body-postoperative pain and disability scale until the 90th day, the time until the first morphine request on the PCA pump, pain scores, and the adverse effects related to the use of study drugs. RESULTS: The KetMag group had a lower morphine consumption by almost 50% during the first 12h than the Control and the Ket groups. In addition, the KetMag group required the first dose of morphine later than the other two groups. There were no differences in the adverse effects of the proposed treatments. Finally, multiple linear regression and a nonlinear approach analysis indicated that the Control group experienced a higher degree of pain and increased morphine consumption per hour than Ket and KetMag groups. CONCLUSION: Co-administration of intraoperative ketamine plus magnesium and ketamine alone are an effective and easy regime for reducing pain and opioid consumption in the postoperative period.

ABSTRACT

Acute compartment syndrome (ACS) is the increase of pressure in a closed osteofascial space. This reduces capillary perfusion below the level necessary for tissue viability. Injury could be irreversible if proper treatment is not performed. Hand ACS secondary to cutaneous loxoscelism with edematous predominance is extremely infrequent. We present a clinical case of a 22-year-old patient who started a hand compartment syndrome secondary to cutaneous loxoscelism (CL), requiring emergency surgical treatment with dorsal and palmar fasciotomy.

ABSTRACT

Resumen El síndrome compartimental agudo (SCA) es el aumento de la presión en un espacio osteofascial cerrado. Esto reduce la presión capilar bajo el nivel necesario para la viabilidad de los tejidos del compartimento. El SCA de mano como complicación de un loxoscelismo cutáneo (LC) de predominio edematoso es muy poco frecuente. Presentamos el caso de una mujer de 22 años que presentó un SCA de la mano secundario a un LC y que requirió tratamiento quirúrgico de urgencia mediante una fasciotomía dorsal y palmar.

ABSTRACT

BACKGROUND: High-definition liposculpture is a novel surgical technique widely accepted among plastic surgeons. The aim of this article is to describe surgical outcomes with a special emphasis on complications in high-definition liposculpture patients. METHODS: An historical cohort of patients who underwent high-definition liposculpture from two senior surgeons was reviewed. Technique, patient selection criteria, preoperative marks and surgical outcomes are described. Postoperative complications are discussed. RESULTS: A total of 417 patients underwent high-definition liposculpture between 2015 and 2018. Primary liposuction and secondary liposuction were performed in 308 (74%) and 109 (26%), respectively. Combined surgeries were performed in 121 cases (29%). There were no systemic complications. Local complications included hyperpigmentation (n = 276), seroma (n = 125), nodular fibrosis (n = 83), unsatisfactory definition in superficial liposuction areas (n = 16), unnatural appearance of body contour (n = 17), VASER-related burns (n = 3) and Mondor's syndrome (n = 2). Most patients (94%) were satisfied with the results. CONCLUSION: High-definition liposculpture is a body contouring technique that has shown excellent results. Despite non-serious complications were frequent, most complications were local and safely treated without affecting surgical outcome. To know these complications will help to recognize them earlier and to adjust patient expectation about the postoperative period.

ABSTRACT

BACKGROUND: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emergent disease that threatens patients with texturized breast implants. Major concerns about the safety of these implants are leading to global changes to restrict the utilization of this product. The principal alternative is to perform breast augmentation utilizing smooth implants, given the lack of association with BIA-ALCL. The implications and costs of this intervention are unknown. OBJECTIVES: The authors of this study determined the cost-effectiveness of smooth implants compared with texturized implants for breast augmentation surgery. METHODS: A tree decision model was utilized to analyze the cost-effectiveness. Model input parameters were derived from published sources. The capsular contracture (CC) rate was calculated from a meta-analysis. Effectiveness measures were life years, avoided BIA-ALCL, avoided deaths, and avoided reoperations. A sensitivity analysis was performed to test the robustness of the model. RESULTS: For avoided BIA-ALCL, the incremental cost was $18,562,003 for smooth implants over texturized implants. The incremental cost-effectiveness ratio was negative for life years, and avoided death and avoided reoperations were negative. The sensitivity analysis revealed that to avoid 1 case of BIA-ALCL, the utilization of smooth implants would be cost-effective for a risk of developing BIA-ALCL equal to or greater than 1:196, and there is a probability of CC with smooth implants equal to or less than 0.096. CONCLUSIONS: The utilization of smooth implants to prevent BIA-ALCL is not cost-effective. Banning texturized implants to prevent BIA-ALCL may involve additional consequences, which should be considered in light of higher CC rates and more reoperations associated with smooth implants than with texturized implants.

ABSTRACT

BACKGROUND: The identification of prognostic factors of gastric cancer (GC) has allowed to predict the evolution of patients. AIM: Assess the reliability of the lymphoparietal index in the prediction of long-term survival in GC treated with curative intent. METHOD: Prospective study of the Universidad de Chile Clinical Hospital, between May 2004 and May 2012. Included all gastric cancer surgeries with curative intent. Exclusion criteria were: gastrectomies due to benign lesions, stage 4 cancers, R1 resections, palliative procedures, complete esophagogastrectomies and emergency surgeries. RESULTS: A total of 284 patients were included; of the sample 65.4% were male,mean age of 64.5 years,75% were advanced cancers, 72.5% required a total gastrectomy, 30 lymph nodes harvest. Surgical morbidity and mortality were 17.2% and 1.7%. 5-year survival was 56.9%. The N+/T index could predict long-term survival in all de subgrups (p<0.0001), although had a reliable prediction in early GC (p=0.005), advanced GC (p<0.0001), signet ring cell GC (p<0.0001), proximal GC (p<0.0001) and distal GC (p<0.0001). The ROC curves N+/T index, LNR and T classification presented areas below the curve of 0.789, 0.786 and 0,790 respectively, without a significant statistical difference (p=0.96). CONCLUSION: The N+/T index is a reliable quotient in the prognostic evaluation of gastric adenocarcinoma patients who have been resected with curative intent.

ABSTRACT

Chest wall shape is an important aspect to consider when planning a breast augmentation. Minor chest wall deformities are usually underestimated by the patient and surgeon and may compromise postoperative outcomes. Lower costal cartilage dysmorphia or winged rib is one of these minor underestimated chest wall deformities characterized by a visible and palpable cartilaginous prominence under the inframammary fold and causes discomfort in patients decreasing the satisfaction with the breast augmentation surgery. For these patients, the author utilized an innovative surgical technique that allows resection of the protruding cartilages and placement of breast implants through the same surgical incision. Six patients with winged ribs underwent breast augmentation and costal cartilage resection via this method and there were no intraoperative or early postoperative complications, and all patients were satisfied with the aesthetical result after 6 months of follow-up. The presented surgical technique has a short learning curve with excellent postoperative results. Cases are presented to demonstrate the improved postoperative chest wall contour combined with breast augmentation outcome.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

ABSTRACT

INTRODUCTION: The aim of the study was to describe the normal orbital volume and its most important relationships with other clinical variables. METHODS: We designed a correlation study and consecutive normal CTs scans were included. Orbital volume and facial anthropometrics were measured and correlated between them. Two independent and blind observers made all the measurements. Uni and multivariate statistical analysis were performed in order to create a predicting model for orbital volume. RESULTS: A total of 199 consecutive patients were included in the study (398 orbits). The mean Orbital Volume (OV) was 24.5 ± 3.08 cc. Adequate intra and interobserver reliability was observed. There were no differences between the right and left orbit (p=0.73). The male average OV was 24.9 ± 3.03 cc, the female OV was 23.9 ± 3.08 cc. Age group analysis demonstrated a slow increase in OV beyond thirty years, but these differences were not significant (p=0.98). Only the age, total facial height, facial width and the interorbital distance were significant and were included in the predictive model of OV. CONCLUSION: We have characterized the normal orbital volume,variations and associations. In order to further advance in the understanding of the clinical implications the abnormal orbital volume must be fully studied.
