RESUMO

BACKGROUND: Fibrous septae play a role in contour alterations associated with cellulite. OBJECTIVE: To assess collagenase clostridium histolyticum-aaes (CCH) for the treatment of cellulite. MATERIALS AND METHODS: Two identically designed phase 3, double-blind, randomized studies (RELEASE-1 and RELEASE-2) were conducted. Adult women with moderate/severe cellulite (rating 3-4 on the Patient Reported Photonumeric Cellulite Severity Scale [PR-PCSS] and Clinician Reported PCSS [CR-PCSS]) on the buttocks received up to 3 treatment sessions of subcutaneous CCH 0.84 mg or placebo per treatment area. Composite response (≥2-level or ≥1-level improvement from baseline in both PR-PCSS and CR-PCSS) was determined at Day 71. RESULTS: Eight hundred forty-three women received ≥1 injection (CCH vs placebo: RELEASE-1, n = 210 vs n = 213; RELEASE-2, n = 214 vs n = 206). Greater percentages of CCH-treated women were ≥2-level composite responders versus placebo in RELEASE-1 (7.6% vs 1.9%; p = .006) and RELEASE-2 (5.6% vs 0.5%; p = .002) and ≥1-level composite responders in RELEASE-1 (37.1% vs 17.8%; p < .001) and RELEASE-2 (41.6% vs 11.2%; p < .001). Most adverse events (AEs) in the CCH group were injection site related; few CCH-treated women discontinued because of an AE (≤4.3%). CONCLUSION: Collagenase clostridium histolyticum-aaes significantly improved cellulite appearance and was generally well tolerated.

RESUMO

Cellulite is characterized by dimpled contour alterations of the skin and is present in approximately 85% to 90% of postpubertal females. Although the pathophysiology of cellulite remains to be fully elucidated, experimental evidence indicates a multifactorial process involving the number and types of fibrous septae, microvascular dysfunction, subcutaneous inflammation, decreased dermal thickness with age, and fat deposition. Cellulite is a major cosmetic concern for many women, and a number of both noninvasive (eg, massage, cosmeceuticals, laser therapy) and minimally invasive techniques (eg, subcision, collagenase injection) have been evaluated to improve the appearance of the affected skin. However, evidence for many of these treatments is limited, largely due to the lack of a validated, convenient tool for the standardized evaluation of cellulite severity. Various imaging modalities have been employed to characterize cellulite severity and the impact of treatment, but only 2-dimensional and 3-dimensional digital photography have been adequately validated. However, in many cases, imaging findings do not correlate with subjective measures of cellulite severity. A number of cellulite rating scales have been developed; some provide only a qualitative measure, whereas others do not fully capture all clinically relevant aspects of cellulite, including the perspective of the patient. There remains an unmet need for global adoption of a validated scale that can be utilized easily by clinicians and patients in clinical and research settings. We propose features that should be included in an ideal rating scale for assessment of cellulite severity.

RESUMO

BACKGROUND: Edematous fibrosclerotic panniculopathy (EFP; cellulite) is associated with thickening and contraction of collagen-rich subdermal septae. Collagenase clostridium histolyticum (CCH) may disrupt collagen-rich septae. OBJECTIVE: To evaluate the safety and efficacy of CCH for treatment of EFP. MATERIALS AND METHODS: In a randomized, double-blind study, women with moderate or severe EFP of the buttocks or posterolateral thighs (i.e., Clinician Reported Photonumeric Cellulite Severity Scale [CR-PCSS] and Patient Reported Photonumeric Cellulite Severity Scale [PR-PCSS] ratings of 3 to 4, and Hexsel Cellulite Severity Scale score ≤13) received up to 3 treatment sessions (Days 1, 22, and 43) of subcutaneous CCH 0.84 mg or placebo injections. End points included the percentage of 2-level and 1-level composite responders (i.e., had ≥2-level or ≥1-level improvement in CR-PCSS and PR-PCSS) at Day 71. RESULTS: Three hundred seventy-five women (mean age, 46.5 years; 86.4% white) were randomly assigned to CCH (n = 189) or placebo (n = 186). At Day 71, the percentages of 2-level and 1-level composite responders were greater with CCH (10.6% and 44.6%, respectively) versus placebo (1.6% and 17.9%; p < .001 for both). The most common adverse events were injection-site related. CONCLUSION: CCH significantly improved EFP appearance versus placebo; further evaluation of CCH for EFP (cellulite) is warranted.

RESUMO

BACKGROUND: Phosphatidylcholine and deoxycholate (PC-DC) injections are a popular nonsurgical method to eliminate unwanted fat. The safety and efficacy of this approach is uncertain. OBJECTIVE: The authors evaluate the effects of PC-DC treatments on body composition, adipocyte function, and mechanisms responsible for fat loss. METHODS: This randomized, open-label study enrolled 13 women with a body mass index (BMI) ≤30 kg/m(2) and lower abdominal subcutaneous fat suitable for small-volume liposuction. Patients were randomized by the final digit of their Social Security numbers and received between 2 and 4 PC-DC treatments, spaced 8 weeks apart. One side below the umbilicus was injected with PC-DC. The contralateral, control side received no treatment. Adipose tissue biopsies were performed on the treated side at baseline, 1 week after the first treatment, and 8 weeks after the final treatment. The primary outcome was change in adipose tissue thickness at baseline and 8 weeks after the final treatment. RESULTS: Seven women completed the study. Treatment with PC-DC significantly reduced the thickness of the anterior subcutaneous abdominal fat (P = .004). Adipose tissue showed rapid increases in crown-like structures, macrophage infiltration, and reduced expression of leptin, hormone-sensitive lipase, adipose tissue triglyceride lipase, and CD36. Plasma C-reactive protein, lipid profile, and plasma glucose concentrations were unchanged. CONCLUSIONS: PC-DC injections can effectively reduce abdominal fat volume and thickness by inducing adipocyte necrosis. These treatments do not appear to increase circulating markers of inflammation or affect glucose and lipid metabolism.

RESUMO

Background: Collagen-rich fibrous septae and subcutaneous adipose protrusions play a role in cellulite pathophysiology. Collagenase clostridium histolyticum-aaes (CCH-aaes) injection causes enzymatic release of septae to resolve cellulite depressions and create a skin smoothing effect. This analysis pooled data from two identically designed, phase-3, randomized, double-blind, placebo-controlled studies to examine the efficacy and safety of CCH-aaes. Methods: Adult women with moderate/severe cellulite (3-4 on Clinician Reported Photonumeric Cellulite Severity Scale and Patient Reported Photonumeric Cellulite Severity Scale) on the buttocks received up to three treatment sessions (Days 1, 22, and 43) of subcutaneous CCH-aaes 0.84 mg or placebo per treatment area. Composite and individual component response (≥2-level or ≥1-level improvement from baseline in Patient Reported Photonumeric Cellulite Severity Scale and/or Clinician Reported Photonumeric Cellulite Severity Scale) and additional patient-reported outcomes were determined at Day 71. Results: Analysis included 424 CCH-aaes-treated and 419 placebo-treated women. CCH-aaes-treated women were 5.9 times more likely than placebo-treated women to be ≥2-level composite responders at Day 71 (odds ratio [95% confidence interval], 5.9 [2.2-15.4]; P < 0.001). A significantly greater percentage of CCH-aaes-treated women versus placebo-treated women were ≥1-level composite responders at Day 71 (39.4% versus 14.6%; P < 0.001). Subgroup analyses indicated no apparent impact of Fitzpatrick skin type category and baseline cellulite severity (moderate/severe) on CCH-aaes efficacy. An inverse relationship between age and CCH-aaes response was observed in those with a body mass index less than 32 kg per m2. The most common adverse events with CCH-aaes were injection-site bruising and injection-site pain. Conclusion: CCH-aaes treatment significantly improved moderate-to-severe buttock cellulite appearance and was generally well tolerated.

RESUMO

Cutaneous scarring is an enormous medical problem with approximately 100 million patients acquiring scars each year. Scar prevention/reduction represents a significant, and largely unmet, clinical need. Research into the prophylactic modulation of scar outcome differs from research into other disease processes as the scar is not present at the start of the study; measurements of changes from baseline are impossible. Final scar morphology is influenced by many variables. A fundamental principle that should be observed in the prospective evaluation of scar prevention/reduction therapies is that, if left untreated, wounds in treatment and control groups should have healed with identical scars. Observation of this principle will allow the detection of true treatment effects. The many variables that influence scar morphology mean that the evaluation of potential pharmaceutical products for this indication favors the use of self-controlled designs in clinical trials. In this article, we review variables that affect scar morphology and recommend the self-controlled design for clinical trials aiming to establish proof of efficacy of scar prevention and reduction pharmaceuticals. With no pharmaceutical products currently licensed for this indication, this represents a new therapeutic area. The principles discussed will also have direct relevance to the wider fields of wound healing and regenerative medicine.

RESUMO

Improvements in infection prevention practices over the past several decades have enhanced outcomes following aesthetic surgery. However, surgical site infections (SSI) continue to result in increased morbidity, mortality, and cost of care. The true incidence rate of SSI in aesthetic surgery is unknown due to the lack of a national surveillance system, but studies of SSI across surgical specialties have suggested that many of these infections are preventable. Patient-related factors-including obesity, glycemic control, and tobacco use-may contribute to the development of SSI following aesthetic surgery. In terms of SSI prevention, proper handwashing and surgical skin preparation are integral. Furthermore, the administration of prophylactic antibiotics has been shown to reduce SSI following many types of surgical procedures. Unfortunately, there are few large, randomized studies examining the role of prophylactic antibiotics in aesthetic surgery. The authors review the medical literature, discuss the risks of antibiotic overutilization, and detail nonpharmacological methods for reducing the risk of SSI.

RESUMO

LEARNING OBJECTIVES: The reader is presumed to have a broad understanding of aesthetic surgical procedures. After studying this article, the participant should be able to: 1. Explain the microbiology of Staphylococcus species and discuss antibiotic resistance development in Staphylococcus species and assess how clinical outcomes are affected. 2. Identify the epidemiology of Staphylococcus carriers and the impact on the clinical practice and regulation. Practice effective measures that prevent surgical site infections. 3. Practice screening for and decolonizing of patients with methicillin-resistant Staphylococcus aureus (MRSA). Physicians may earn 2.5 AMA PRA Category 1 Credit by successfully completing the examination based on material covered in this article. The examination begins on page 245. As a measure of the success of the education we hope you will receive from this article, we encourage you to log on to the Aesthetic Society website and take the preexamination before reading this article. Once you have completed the article, you may then take the examination again for CME credit. The Aesthetic Society will be able to compare your answers and use this data for future reference as we attempt to continually improve the CME articles we offer. ASAPS members can complete this CME examination online by logging on to the ASAPS Members-Only Website (http://www.surgery.org/members) and clicking on "Clinical Education" in the menu bar. Staphylococcus aureus is the most common cause of surgical site infections (SSI), with both methicillin-sensitive and methicillin-resistant strains causing these infections. The incidence of methicillin-resistant S aureus (MRSA) has increased in the US over the past decade, largely due to the emergence of community-acquired MRSA (CA-MRSA). This article reviews the microbiology and epidemiology of methicillin-sensitive S aureus (MSSA) and MRSA, risk factors for surgical site infections among plastic surgery patients, the evidence supporting preoperative screening and decolonization measures to prevent surgical site infections caused by MRSA, recommendations for anti-microbial prophylaxis, and treatment recommendations for surgical site infections. Other proven methods of reducing SSI, including maintenance of normothermia during surgery, glucose control, cessation of nicotine use, and not shaving the surgical site preoperatively are discussed.

RESUMO

BACKGROUND: The number of cosmetic surgical and nonsurgical procedures performed in the United States has increased by 500% over the past 10 years. Most studies of psychosocial functioning following aesthetic procedures have reported high levels of patient satisfaction and improved functioning; however, nearly all these studies focused only on changes during the first posttreatment year. OBJECTIVE: This paper reports on the 2-year results of a prospective, multi-site investigation of postoperative satisfaction and changes in psychosocial status following cosmetic surgery. METHODS: One hundred patients from 8 surgical practices completed psychometric measures of body image, depressive symptoms, and self-esteem before surgery. Patients completed the same measures again at 3, 6, 12, and 24 months postoperatively. In addition, they reported their postoperative satisfaction as well as self-rated attractiveness at the 4 postoperative assessment points. RESULTS: Patients reported improvements in their overall appearance and body image, the appearance of and their degree of dissatisfaction with the feature altered by surgery, and the frequency of negative body image emotions in specific social situations through 24 months after surgery. These improvements were first evident at 3 months postoperatively and were maintained, without deterioration, through 2 years following surgery. CONCLUSIONS: Patients reported high rates of satisfaction and improvements in body image within the first 3 months of cosmetic surgery. These improvements were well maintained through the first 2 postoperative years.

RESUMO

BACKGROUND: Liposuction has been proposed as a potential treatment for the metabolic complications of obesity. We evaluated the effect of large-volume abdominal liposuction on metabolic risk factors for coronary heart disease in women with abdominal obesity. METHODS: We evaluated the insulin sensitivity of liver, skeletal muscle, and adipose tissue (with a euglycemic-hyperinsulinemic clamp procedure and isotope-tracer infusions) as well as levels of inflammatory mediators and other risk factors for coronary heart disease in 15 obese women before and 10 to 12 weeks after abdominal liposuction. Eight of the women had normal glucose tolerance (mean [+/-SD] body-mass index, 35.1+/-2.4), and seven had type 2 diabetes (body-mass index, 39.9+/-5.6). RESULTS: Liposuction decreased the volume of subcutaneous abdominal adipose tissue by 44 percent in the subjects with normal glucose tolerance and 28 percent in those with diabetes; those with normal oral glucose tolerance lost 9.1+/-3.7 kg of fat (18+/-3 percent decrease in total fat, P=0.002), and those with type 2 diabetes lost 10.5+/-3.3 kg of fat (19+/-2 percent decrease in total fat, P<0.001). Liposuction did not significantly alter the insulin sensitivity of muscle, liver, or adipose tissue (assessed by the stimulation of glucose disposal, the suppression of glucose production, and the suppression of lipolysis, respectively); did not significantly alter plasma concentrations of C-reactive protein, interleukin-6, tumor necrosis factor alpha, and adiponectin; and did not significantly affect other risk factors for coronary heart disease (blood pressure and plasma glucose, insulin, and lipid concentrations) in either group. CONCLUSIONS: Abdominal liposuction does not significantly improve obesity-associated metabolic abnormalities. Decreasing adipose tissue mass alone will not achieve the metabolic benefits of weight loss.

RESUMO

The Center for Implant Retrieval and Analysis has been established at Washington University's Division of Plastic and Reconstructive Surgery for the purpose of studying implantable devices retrieved after surgery or autopsy and assessing their condition after implantation. Since the early 1990s, significant experience has been gained in testing and analyzing silicone gel breast implants and, to a lesser extent, saline-filled devices. However, there has been no systematic method reported for collecting and evaluating these implants in a way that would permit di. erent laboratories to compare their data. This article offers the plastic and reconstructive surgery community a standardized protocol for analyzing explanted silicone gel and saline-filled breast implants. The protocol gives surgeons a clearly defined approach for removing, handling, documenting, and shipping explanted breast implants. At the same time, biomaterials researchers can use the protocol to acquire implant data with reliable and reproducible methods. Because the study of saline implants has lagged behind the study of silicone gel implants, the article concludes with a demonstration of how this protocol can be applied to obtain mechanical properties data and use scanning electron microscopy to illuminate failure mechanisms of saline devices, including three explants removed after 20+ years in vivo.

RESUMO

This article describes some of the major anatomical issues that confront plastic surgeons when contouring and augmenting the gluteal region. A better understanding of anatomy can improve the cosmetic results of gluteal augmentation and thereby enhance patient satisfaction. More importantly, this knowledge can reduce the risks of complications, some of which may have long-term adverse effects.

RESUMO

LEARNING OBJECTIVES: The reader is presumed to have a broad understanding of plastic surgical procedures and concepts. After studying this article, the participant should be able to: Physicians may earn 1 AMA PRA Category 1 credit credit by successfully completing the examination based on material covered in this article. The examination begins on page 176. ASAPS members can also complete this CME examination online by logging onto the ASAPS Members-Only Web site (http://www.surgery.org/members) and clicking on "Clinical Education" in the menu bar. Little has been published about venous thromboembolism (VTE) complications in plastic surgery. The authors investigated the recent literature, particularly literature reviews and meta-analyses of clinical studies, in order to outline strategies for prevention of deep vein thrombosis (DVT) and pulmonary embolism (PE) applicable to plastic surgery patients. Major risk factors for VTE include trauma, a prior history of VTE, older age, use of oral contraceptives or hormone replacement therapy, and prolonged travel. Although the frequency of VTE among plastic surgery patients is estimated to be from less than 1% to 2% of cases, in fact many of our patients are at moderate to high risk of VTE. Moreover, the actual frequency of VTE among plastic surgery patients is probably higher than we know, because up to two thirds of cases are asymptomatic. Mechanical methods of VTE prophylaxis include graduated compression stockings (GCSs), intermittent pneumatic compression (IPC) devices, and venous foot pumps (VFPs). They are recommended primarily for patients with a high risk of bleeding or as an adjunct to chemoprophylaxis. Intermittent pneumatic compression devices were found to be more effective than passive compression using GCSs. For plastic surgery patients, IPC devices or VFPs are recommended for any procedure that lasts more than 1 hour, and for all patients receiving general anesthesia. Use should begin 30 to 60 minutes before surgery. Low-molecular-weight heparin (LMWH) is the most widely used form of DVT/PE prophylaxis. Other forms of chemoprophylaxis are coming onto the market or under development. In particular, fondaparinux, an indirect FXa inhibitor, was approved in 2004 for VTE prophylaxis in orthopedic surgery. Studies have indicated that it is significantly more effective than LMWH after joint replacement, hip fracture surgery, and in cancer patients. Other drugs in development include idraparinux, another indirect FXa inhibitor, direct FXa inhibitors, and several direct thrombin inhibitors. Plastic surgeons have generally been reluctant to use antithrombotic agents because of the increased risk of bruising or hematoma and the possible need for blood transfusion. However, numerous studies have found little or no increase in the frequency of clinically important bleeding associated with their use. Some plastic surgeons now routinely use chemoprophylaxis in patients undergoing abdominoplasty, combined procedures, or procedures lasting more than 4 hours. The authors also recommend postoperative chemoprophylaxis in circumferential body contouring, thighplasty, surgery requiring open space dissection, transverse rectus abdominus muscle (TRAM) procedures, and surgical procedures likely to contribute to venous stasis or compression. It is impractical and expensive to screen every patient for asymptomatic DVT. A patient history focusing specifically on VTE risk factors should be performed within a few weeks of surgery. Patient education should include information about the symptoms of DVT and PE (including the fact that most patients with VTE are asymptomatic) and a full explanation of the risks and benefits of anticoagulant prophylaxis.

RESUMO

While inadvertent perioperative hypothermia has received serious attention in many surgical specialties, few discussions of hypothermia have been published in the plastic surgery literature. This article reviews the physiology of thermoregulation, describes how both general and regional anesthesia alter the normal thermoregulatory mechanisms, indicates risk factors particularly associated with hypothermia, and discusses the most effective current methods for maintaining normothermia. Hypothermia is typically defined as a core body temperature of /=36.5 degrees C is maintained. Unless preventive measures are instituted, inadvertent hypothermia occurs in 50% to 90% of surgical patients, even those undergoing relatively short procedures lasting one to one-and-a-half hours. During either general or regional anesthesia, a patient's natural behavioral and autonomic responses to cold are unavailable or impaired, and the combination of general and neuraxial anesthesia produces the highest risk for inadvertent perioperative hypothermia. Unless hypothermia is prevented, the restoration of normothermia can take more than 4 hours once anesthesia is stopped. Consequences of hypothermia are serious and affect surgical outcomes in plastic surgery patients. Potential complications include morbid cardiac events, coagulation disorders and blood loss, increased incidence of surgical wound infection, postoperative shivering, longer hospital stays, and increased costs associated with surgery. Measures for preventing hypothermia are emphasized in this article, especially those proven most effective in prospective and controlled clinical studies. Perhaps the most important step in maintaining normothermia is to prewarm patients in the preoperative area with forced-air heating systems. Intraoperative warming with forced-air and fluid warming are also essential. Other strategies include maintaining an ambient operating room temperature of approximately 73 degrees F (22.8 degrees C), covering as much of the body surface as possible, and aggressively treating postoperative shivering. None of these measures can be adequately employed unless a patient's core body temperature is monitored throughout the perioperative period. Prevention of perioperative hypothermia is neither difficult nor expensive. Proper preventive measures can reduce the risk of complications and adverse outcomes, and eliminate hours of needless pain and misery for our patients.

RESUMO

The authors point out that dimethyl sulfoxide (DMSO) increases tissue perfusion and may effectively treat or prevent ischemia in flaps. They recommend application of topical DMSO every 4 to 6 hours, until blood flow improves, to areas that show signs of ischemia or less than adequate perfusion. Other potential cosmetic surgery uses of DMSO include areas of skin care, pain relief, and treatment of keloids.

RESUMO

BACKGROUND: Although several studies have investigated patient satisfaction and changes in body image following aesthetic plastic surgery, few have investigated more specific dimensions of body image, including dysphoric emotions that occur in specific social situations or body image quality of life. In addition, few studies have investigated changes in body image that may occur in concert with changes in more general areas of psychosocial functioning, such as depressive symptoms and self-esteem. OBJECTIVE: This prospective, multi-site study investigated postoperative satisfaction and changes in psychosocial status following cosmetic surgery. METHODS: One hundred patients recruited from 8 geographically diverse surgical practices completed psychometric measures of body image, depressive symptoms, and self-esteem prior to surgery. Seventy-two patients completed the 3-month postoperative assessment, 67 completed the 6-month assessment, and 63 completed the 12-month assessment. All statistical tests on changes after surgery were conducted using the sample of 72 patients who completed the 3-month assessment. A Last Observation Carried Forward analysis was used to account for patients who did not complete the subsequent follow-up assessments. In addition, they reported their postoperative satisfaction as well as self-rated attractiveness at the 3 postoperative assessment points. RESULTS: Eighty-seven percent of patients reported satisfaction with their postoperative outcomes. Patients also reported significant improvements in their overall appearance, as well as the appearance of the feature altered by surgery, at each of the postoperative assessment points. Patients experienced significant improvements in their overall body image, their degree of dissatisfaction with the feature altered by surgery, and the frequency of negative body image emotions in specific social situations. All of these improvements were maintained 12 months after surgery. CONCLUSIONS: These results add to a growing body of literature documenting improvements in body image following cosmetic surgery.

RESUMO

BACKGROUND: There is a growing concern for microbial resistance as a result of overuse of antibiotics. Although guidelines have focused on the use of antibiotics for surgery in general, few have addressed plastic surgery specifically. The objective of this expert consensus conference was to evaluate the evidence for efficacy and safety of antibiotic prophylaxis in plastic surgical procedures. METHODS: THE AUTHORS: searched for existing high-quality systematic reviews for antibiotic prophylaxis in the literature from the MEDLINE, Cochrane Library, and Embase databases. All synonyms for antibiotics were combined with terms for relevant plastic surgery procedures. The searches were not limited by language, and included all study designs. In addition, supplemental hand searches were performed of bibliographies of relevant articles, and extensive "related articles." Meta-analyses were performed and reviewed by experts selected by the American Association of Plastic Surgeons to reach consensus recommendations. RESULTS: Database searches identified 4300 articles, from which 2042 full-text articles were identified for eligibility. De novo meta-analyses were performed for each plastic surgical category. In total, 67 studies met the inclusion criteria, including nine for breast surgery, 17 for head and neck surgery, 10 for orthognathic surgery, seven for rhinoplasty/septoplasty, 19 for hand surgery, five for skin surgery, and two for abdominoplasty. CONCLUSIONS: Systemic antibiotic prophylaxis is recommended for clean breast surgery and for contaminated surgery of the hand or the head and neck. It is not recommended to reduce infection in clean surgical cases of the hand, skin, head and neck, or abdominoplasty.

RESUMO

Prophylactic bilateral mastectomy has been demonstrated to reduce breast cancer incidence in women with a high inherited susceptibility to breast cancer. For the majority of high-risk women, however, bilateral prophylactic mastectomy is not an acceptable option for primary prevention of breast cancer. Several epidemiological follow-up studies have indicated that there may be a substantial reduction in breast cancer risk among women who have undergone breast reduction surgery. The authors reviewed the evidence from these studies, with emphasis on the problems inherent in interpreting the results of nonexperimental studies of elective medical procedures. Although such observational studies cannot demonstrate definitively that reduction mammaplasty reduces the risk of breast cancer, the evidence from these studies is sufficiently strong to warrant the evaluation of breast reduction surgery as an option for primary prevention in clinical studies of women at increased risk of breast cancer. The availability of a more acceptable surgical option for primary prevention of breast cancer could increase the number of women willing to choose risk reduction surgery and thus may result in an overall reduction in breast cancer mortality among high-risk women.
