The biological effects of quadripolar radiofrequency sequential application: a human experimental study.

An experimental study was conducted to assess the effectiveness and safety of an innovative quadripolar variable electrode configuration radiofrequency device with objective measurements in an ex vivo and in vivo human experimental model. Nonablative radiofrequency applications are well-established anti-ageing procedures for cosmetic skin tightening. The study was performed in two steps: ex vivo and in vivo assessments. In the ex vivo assessments the radiofrequency applications were performed on human full-thickness skin and subcutaneous tissue specimens harvested during surgery for body contouring. In the in vivo assessments the applications were performed on two volunteer patients scheduled for body contouring surgery at the end of the study. The assessment methods were: clinical examination and medical photography, temperature measurement with thermal imaging scan, and light microscopy histological examination. The ex vivo assessments allowed for identification of the effective safety range for human application. The in vivo assessments allowed for demonstration of the biological effects of sequential radiofrequency applications. After a course of radiofrequency applications, the collagen fibers underwent an immediate heat-induced rearrangement and were partially denaturated and progressively metabolized by the macrophages. An overall thickening and spatial rearrangement was appreciated both in the collagen and elastic fibers, the latter displaying a juvenile reticular pattern. A late onset in the macrophage activation after sequential radiofrequency applications was appreciated. Our data confirm the effectiveness of sequential radiofrequency applications in obtaining attenuation of the skin wrinkles by an overall skin tightening.

Changing Body Image and Well-Being: Following the Experience of Massive Weight Loss and Body Contouring Surgery.

This paper reports on the perception of changing body image and well-being for patients who had undergone plastic surgery following massive weight loss. The exploratory, qualitative study was undertaken with 20 patients from one teaching hospital in the south of England. Semi-structured interviews were carried out and a thematic analysis of the data undertaken. The results provide important insights regarding body contouring influencing body image change and the adjustment process involved. The ability to pursue self-esteem and the accruing social benefits is emphasized in the interrelated sub themes including social acceptance, undoing depression and sexual vitality. Body contouring surgery following massive weight loss appears to facilitate improvement in body image and well-being. Adjustment to the changing body image is both empowering and challenging. Supportive educational programmes need to be developed to assist this transition to a more positive body image and appreciation; these could usefully include access to and involvement with patient support groups.

Weiterbildung in der ästhetischen Chirurgie an einer Universitätsklinik – Das „Münchner Modell“

Aesthetic surgery is regarded as one of the 4 pillars of plastic surgery. To assure safety in this field of surgery, a structured and well guided surgical training is indispensable. However, during the specialist training for plastic and aesthetic surgery, plastic aesthetic interventions are often carried out in low numbers only. Objective of the present study was the development, implementation and evaluation of a new training concept in aesthetic surgery. Over a period of 2 years, 304 aesthetic operations were performed in the fields of body contouring, breast surgery and facial surgery as an "educational surgery". Educational surgeries were performed by resident surgeons under the guidance of experienced specialists and under favourable financial conditions. As indicator for safety of the interventions, the incidence of complications was recorded and assessed. Out of a total of 304 operations included in the study 47.7% were performed as an educational surgery. In the fields of body contouring and breast surgery, the majority of interventions (51.3% and, respectively, 53%) were carried out as educational surgeries. In aesthetic surgeries of the face only 28.4% were educational surgeries. In 4.9% of all cases complications occurred. The incidences of complications were approximately the same in the educational surgeries (5.5%) and in the surgeries carried out by experienced specialists (4.4%), showing no significant difference. The presented training concept aims at ensuring high quality in patient care by structure and quality of surgical training. Our data give evidence that a structured training of residents in the field of aesthetic surgery is possible without loss in quality. We expect that -sufficient surgical education and the associated quality will consequently contribute to keep aesthetic surgeries a domain of plastic surgery and to prevent these procedures from being taken over by other surgical disciplines.

Strategy to Minimize Oral Mucosal Tear and Lip Injury in Facial Contouring and Orthognathic Surgery

In this article, the authors present a simple but effective technical strategy to protect the lip and mucosa from iatrogenic thermal injury and traumatic mucosal tear in orthognathic and aesthetic facial contouring surgery. During surgical exposure and osteotomy, a piece of double-layered Vaseline dressing gauze is strategically placed over the lip and mucosal tissues before the application of the Obwegeser or Gimma retractors. The objective is to avoid traumatic and thermal injury to the lip and mucosal tissues during the use of various retractors and other craniomaxillofacial dynamic instruments in such surgery. In our experience of consecutive 400 intraoral osteotomy procedures over the last 5 years of using the double-layered Vaseline gauze to protect the lip tissues and oral mucosa, there was no incidence of any unintentional complications of thermal injury and tears of the lip and mucosa. It is simple and effective with minimum learning curve, but most importantly it has significantly minimized the morbidity associated with lip thermal injury and mucosal tear in these patients.

Demographic Factors, Outcomes, and Complications in Abdominal Contouring Surgery After Massive Weight Loss in a Developing Country

Few reports about body contouring surgery after massive weight loss (MWL) have been produced in the developing countries. As Mexico is considered a developing country, we performed a retrospective analysis of medical records of patients who underwent this type of surgery to evaluate their demographic characteristics as well as their outcomes and complications. Results from 684 patients with MWL, 69 (10%) had abdominoplasty; the type of abdominoplasty influenced the operative time, bleeding, and complications (P < 0.05); the body mass index influenced the weight of resected tissue (P < 0.000) and hospital stay (P < 0.020), but did not affect the type of abdominoplasty performed, surgical time, complications, reoperation, or transfusion rates. In contrast with the developed countries, in these procedures, operating time was higher and the patients had more surgical bleeding with higher rates of transfusion and a longer hospital stay, but with the same clinical results and percentage of complications.

Use of Rapidly Hardening Hydroxyapatite Cement for Facial Contouring Surgery

Hydroxyapatite cement is an ideal alloplastic material to replace the autogenous bone grafts in craniofacial surgery. Hydroxyapatite cement is advantageous because it can be easily molded by hand unlike other alloplastic materials such as silicone and high-density polyethylene. For aesthetic applications of hydroxyapatite cement, we evaluated the efficacy and safety of the rapidly hardening hydroxyapatite cement used in facial contour augmentation, especially for the forehead and the malar area. A total of 18 cases of facial skeleton augmentation or contouring surgery using rapidly hardening hydroxyapatite cement (Mimix; Biomet, Warsaw, IN) were examined, and the long-term cosmetic results and any complications were also analyzed. The aims of facial contouring surgeries were to correct the following conditions: hemifacial microsomia, craniosynostosis, posttraumatic facial deformity, deformity after tumor resection, dentofacial deformity, and Romberg disease. The application sites of hydroxyapatite cement were the forehead, malar area, chin, and paranasal area. A mean of 16 g (range, 5-50 g) of the hydroxyapatite cement was used. Postoperative infection, seroma, and migration of the implant were not observed during the follow-up period of 23 months. Rapidly hardening hydroxyapatite cement, Mimix, is easy to manipulate, promptly sclerotized, and can be replaced by living bone tissue, with a low complication rate. Therefore, it can be an optimal treatment that can be used instead of other conventional types of alloplastic materials used in facial contouring surgery.

Complications of Abdominal Contouring Surgery in Obese Patients

Medical records of 122 patients who underwent an abdominoplasty or panniculectomy from 2003 to 2008 were reviewed to determine current rates of wound complications associated with these procedures in the presence of obesity. An additional aim was to determine current rates of complications as compared with those found 10 years ago at our institution to determine if the finding of obesity alone continues to adversely affect wound outcomes. Sixty-three of 122 patients (51.6%) experienced 1 or more wound-related complications. Major complications occurred in 13 patients (10.7%). A striking finding was that the lowest major complication rate 4.5%, was found in patients with extreme obesity (BMI >40). Comparisons between the 1999 and current studies found that the difference in major complications in those classified as obese, with 2 (9%) in the current study and 8 (40%) in the 1999 study, was significant (P = 0.039). Our findings suggest that high rates of major complications found in those with obesity in the 1999 study are not found today. Extreme obesity is not an absolute contraindication to operation and may be performed safely.

Intraoperative Three Dimensional Correction During In Situ Contouring Surgery by Using a Numerical Model

A numerical study was conducted by simulating in situ contouring (ISC) surgery. To quantify intraoperative correction during ISC surgery. Surgical techniques correcting scoliosis, like the ISC one, lead to a complex 3-dimensional correction of the spine. Using motion analysis devices to analyze the effect of intraoperative surgical maneuvers was tedious and limited the study to the kinematics of exposed vertebrae. An alternative method consisted in simulating the surgical gestures. However, proposed models were based on rigid instrumentations, and focused attention on specific gestures of the rod-rotation and the distraction techniques through operator-dependent simulations. This study included 10 patients with severe idiopathic scoliosis treated by ISC surgery. From a patient-specific finite-element model (T1-L5 and pelvis), all main steps of the ISC surgery were automatically simulated. A specific algorithm was developed to determine the sequences of bending maneuvers according to the rod shapes chosen by the surgeon. The accuracy of the automated surgery simulation was assessed regarding the virtual postoperative spinal configuration and postoperative clinical data. For each maneuver, vertebral kinematics was computed as well as the evolution of various clinical parameters. The bending maneuvers of both the first and the second rods provided complementary effects inside, but also outside the fused spinal area. These main maneuvers combined the intraoperative spinal corrections induced by maneuvers specific to the rod-rotation surgery. The automated patient-specific simulation of ISC surgery may improve the understanding of the main mechanisms involved in the scoliosis surgical correction.

Procedural Risk for Venous Thromboembolism in Abdominal Contouring Surgery: A Systematic Review of the Literature

To ensure that patients receive appropriate thromboembolic prophylaxis, other specialties have begun using risk stratification models. Because these models do not include plastic surgery patients, research must be directed toward exploring the risk associated with these operations. A systematic review of the literature was performed to address these issues. A thorough search for all articles discussing abdominal contouring surgery was conducted. Data were collected from this institution through a retrospective chart review and included in the analysis. Procedures were divided into four groups, dependent on what was reported, as follows: abdominoplasty alone, abdominoplasty with an intraabdominal procedure, abdominoplasty with another plastic surgical procedure, and circumferential abdominoplasty. Frequencies of venous thromboembolism were recorded. Chi-square analysis was performed to examine for statistical differences. One hundred fourteen articles were reviewed; 30 articles were included in the analysis. Circumferential abdominoplasty was associated with the highest venous thromboembolism rate (3.40 percent). This was statistically higher than the thromboembolic rate of abdominoplasty (0.35 percent) (p < 0.0001) and abdominoplasty with concomitant plastic surgery (0.79 percent) (p < 0.0001). Abdominoplasty combined with an intraabdominal procedure was associated with the second highest rate of thromboembolism (2.17 percent). This rate was higher than abdominoplasty alone (p < 0.001) and abdominoplasty with concomitant plastic surgery (p = 0.02). Circumferential abdominoplasty and abdominoplasty performed in combination with an intraabdominal procedure were demonstrated to have significantly increased risk for venous thromboembolism. Patients undergoing these procedures should be risk stratified and have perioperative prophylaxis managed accordingly. It is suggested that both of these operations be placed into a higher exposing risk category within the modified Davison-Caprini risk assessment model.

Facial Contouring Surgery for Asians

Asian people, especially women, prefer a more delicate and feminine facial shape. To achieve a softer and better facial contour, there are several procedures to change the facial skeleton. Reduction malarplasty and mandibular angleplasty are common facial contouring operations in Asia. A lot of techniques have been developed independently by several authors. Various approaches can be chosen, such as intraoral or external skin incisions. There as also different contouring methods that can be chosen depending on the patient's morphology and the surgeon's technical preferences. The different osteotomy techniques used to mobilize the zygomatic complex can be classified according to the specific portion that is being repositioned. Resection and contouring methods for a prominent mandibular angle can be subdivided according to the specific type of anomaly. The purpose of this article is to review the concepts and various operative procedures for reduction malarplasty and angleplasty. The authors propose a guideline for selecting the appropriate procedure(s) for individual patients. Decisions should be made according to the patient's need, anatomic variations, and possible operative sequelae.

Maintenance of Weight Loss after Body Contouring Surgery for Massive Weight Loss

Weight loss can be achieved through gastric bypass surgery or diet. Surgery has been reported to be more effective in achieving long-term weight loss. The authors aimed to determine whether massive weight loss is maintained or improved after body contouring. Seventy patients underwent body contouring surgery after massive weight loss from January of 2001 to January of 2005. Data collected included age; gender; mode of massive weight loss; body mass index before massive weight loss, at contour surgery, and at follow-up; and weight of skin excised. Weight loss was achieved by open (n = 57) or laparoscopic gastric bypass surgery (n = 7), or by diet (n = 6). Average weight loss at contour surgery was 152 lb for open gastric bypass, 139 lb for laparoscopic gastric bypass, and 140 lb for the diet group. Mean weight of excised skin was 12.8 lb. Gastric bypass patients on average gained 2.3 lb, whereas nonsurgical patients gained 22 lb after body contouring, netting out skin excised. On multivariate analysis, weight loss did not differ between laparoscopic and open gastric bypass (p = 0.9); however, surgery led to a 27-lb greater weight loss compared with diet (p = 0.03). This effect was more remarkable with follow-up less than or equal to 18 months compared with more prolonged follow-up. Every year increase in age was associated with an 0.8-lb weight gain (p = 0.03). Gastric bypass surgery patients maintain massive weight loss better than "diet" patients. Weight loss tapers over time for gastric bypass surgery patients, with ultimate weight gain, comparable to that seen in the general population as it ages.

Chest-Wall Contouring Surgery in Female-to-Male Transsexuals: A New Algorithm

In female-to-male transsexuals, the first surgical procedure in their reassignment surgery consists of the subcutaneous mastectomy. The goals of subcutaneous mastectomy are removal of breast tissue, removal of excess skin, reduction and proper positioning of the nipple and areola, and ideally, minimization of chest-wall scars. The authors present the largest series to date of female-to-male transsexuals who have undergone subcutaneous mastectomy. A total of 184 subcutaneous mastectomies were performed in 92 female-to-male transsexuals, using the following five techniques: semicircular, transareolar, concentric circular, extended concentric circular, and free nipple graft. The technique used depended on the breast size and envelope, the aspect and position of the nipple-areola complex, and the skin elasticity. To best meet the goals of creating a normal male thorax, the authors have developed an algorithm to aid in choosing the appropriate procedure. The overall postoperative complication rate was 12.5 percent (23 of 184 subcutaneous mastectomies), and in eight of these cases (4.3 percent), an additional operative intervention was required because of hematoma, infection, and/or wound dehiscence. Despite this low complication rate, additional procedures for improving aesthetic results were performed on 59 breasts (32.1 percent). The semicircular and concentric circular techniques produced the highest rating of the overall result by patient and surgeon, whereas the extended concentric circular technique produced the lowest rating. Skin excess and skin elasticity are the key factors in choosing the appropriate technique for subcutaneous mastectomy, which is reflected in the algorithm. Although the complication rate is low and patient satisfaction is high, secondary aesthetic corrections are often indicated.

Facial contouring review of 100 cases and new concepts

Objectives: Multiple factors contribute to the aesthetically pleasing face including: skin, soft tissue, bony contours and cultural norms. Surgery for facial contouring consist of jaw surgery, rhinoplasty, facial implantation, chin malar and submalar contouring, mandible, orbit, maxilla and pyriform surgery. In this article we will review 100 patients who have undergone facial contouring surgery and study the effect of each type of surgery in the facial contours. Methods: One hundred patients were included in this study with measuring of facial contours both preoperative and postoperative. The results were compared in each technique and we find the numerical changes after each surgery. Results and conclusions: In some of the surgeries in face like orthognathic surgery we can predict the results before doing it, but especially in soft tissue surgeries in the face it is not so easy to predict the results as the numerical changes. By using the result of this study we can go toward the prediction of the facial contouring surgeries.

Abdominoplasty and Abdominal Contour Surgery: A National Plastic Surgery Survey

According to the American Society for Aesthetic Plastic Surgery's 2004 Cosmetic Surgery National Data Bank, during the last 7 years, the number of abdominoplasty procedures performed has increased 344 percent. A national report on abdominoplasty has not been since 1977. Grazer and Goldwyn's study reflects the preliposuction era of abdominal contouring surgery. The purpose of this study was to assess current trends in abdominal contouring techniques and associated procedures and the incidence of their complications. The study was designed as a descriptive correlation survey evaluating the frequency of various abdominal contour techniques and complications among 3300 randomly chosen members of the American Society of Plastic Surgeons. There were 497 respondents, for a response rate of 15 percent. A total of 20,029 procedures were reported in the survey; 35 percent (n = 7010) were liposuction of the abdomen, 10 percent (n = 2003) were limited abdominoplasties, and 55 percent (n = 11,016) were full abdominoplasties. Survey data covered the plastic surgeon's demographics, techniques, and incidence of complications during a 12-month period. The authors report the largest series of local and systemic complication rates and compare them with those of previously published abdominoplasty surveys. With respect to full abdominoplasty, lower complication rates for deep vein thrombosis (0.04 percent) and pulmonary embolus (0.02 percent) were seen. No deaths were reported. There was no correlation between a surgeon's years in practice and complication rates, in concordance with the earlier study by Grazer and Goldwyn. Despite more extensive abdominal contouring techniques and the addition of liposuction to abdominal contouring, the local and systemic complication rates coincided with previous complication rates, as outlined in other studies.

The Contact YAG Laser in Body Contouring Surgery

The contact Neodium: YAG laser has advantages over conventional cold-knife surgery of electrocautery in body contouring and reconstructive surgery. Clinically the Nd: YAG laser causes less damage to surrounding tissues than the electrocautery when used for dissection. It provides hemostasis simultaneously during surgery that is advantageous over conventional cold-knife surgery. Patients may have an easier recovery after surgery with the contact YAG laser than after surgery with the electrocautery.
