RESUMEN

BACKGROUND: Direct-to-implant (DTI) breast reconstruction after mastectomy has gained increasing popularity. While concerns over ischemic complications related to tension on the mastectomy flap persist, newer techniques and technologies have enhanced safety of this technique. OBJECTIVES: To compare clinical and patient-reported outcomes of DTI and 2-stage tissue expander (TE) reconstruction. METHODS: A prospective cohort design was utilized to compare the incidence of reconstructive failure among patients undergoing DTI and TE reconstruction by unadjusted bivariate and adjusted multivariable logistic regression analyses. Secondary clinical outcomes of interest included specific complications requiring intervention (infection, seroma, hematoma, mastectomy flap necrosis, incisional dehiscence, device exposure) and time to final drain removal. Patient-reported outcomes on BREAST-Q were also compared. RESULTS: A total of 134 patients (257 breasts) underwent DTI reconstruction and 222 patients (405 breasts) received TEs. DTI patients were significantly younger with lower BMIs; less diabetes, hypertension, and smoking; and smaller breast sizes; they also underwent more nipple-sparing mastectomies with prepectoral reconstructions. Rates of any complication (18% DTI vs 24% TE, P = .047), reconstructive failure (5.1% vs 12%, P = .004), and seroma (3.9% vs 11%, P < .001) were significantly lower in the DTI cohort on unadjusted analyses; however, there were no significant differences on adjusted regressions. Patient-reported satisfaction with breasts, psychosocial well-being, and sexual well-being were more substantively improved with DTI reconstruction. CONCLUSIONS: Prepectoral DTI reconstruction is a viable option for postmastectomy reconstruction in carefully selected patients, with no significant increase in reconstructive failure or other complications.

RESUMEN

PURPOSE: Breast cancer is diagnosed at a median age of 62 years in the USA. At the same time, mortality rates for breast cancer continue to decrease, falling by 40% from 1989 to 2016. In the coming decades, the number of elderly patients with breast cancer, potentially seeking reconstruction, is expected to increase. METHODS: A retrospective chart review of 309 patients, aged 60 years or older, undergoing immediate or delayed breast reconstruction, was conducted. Patient characteristics, clinical information and major complications requiring reoperation were evaluated. Multivariate analyses identified factors contributing to complications such as BMI, comorbidities, smoking status, history of previous breast conservation therapy (BCT), total expander volume, radiotherapy, and chemotherapy. RESULTS: 26.7% of patients had at least one complication requiring reoperation, and 6.9% of patients suffered reconstructive failure. Logistic regression analysis of all patients (n = 309) found a statistically significant relationship between major complication and history of ipsilateral BCT (p = 0.026) and adjuvant chemotherapy (p = 0.005). Logistic regression analysis in patients undergoing tissue expander (TE) reconstruction (n = 215) showed that major complications were related to BMI over 35 kg/m2 (p = 0.04), history of ipsilateral BCT (p = 0.048), and adjuvant chemotherapy (p = 0.033). CONCLUSION: Breast reconstruction in women over 60 years old was not independently associated with higher major complication rates in our series.

RESUMEN

PURPOSE: We explored the impact of the relative volume of a tumor versus the entire breast on outcomes in patients undergoing breast conservation therapy (BCT) versus mastectomy and reconstruction (M + R). We hypothesized that there would be a threshold tumor:breast ratio (TBR) below which patient-reported outcomes (PRO) would favor BCT and above which would favor M + R. METHODS: We conducted a prospective cohort study of patients with ductal carcinoma in situ (DCIS) or invasive breast cancers undergoing BCT or M + R. A prerequisite for inclusion, analysis of tumor and breast volumes was conducted from three-dimensional magnetic resonance imaging reconstructions to calculate the TBR. Three-dimensional photography was utilized to calculate pre- and postoperative volumes and assess symmetry. Oncologic, surgical, and patient-reported outcome data were obtained from relevant BREAST-Q modules administered pre- and postoperatively. RESULTS: The BCT cohort had significantly smaller tumor volumes (p = 0.001) and lower TBRs (p = 0.001) than patients undergoing M + R overall. The M + R group, however, comprised a broader range of TBRs, characterized at lower values by patients opting for contralateral prophylactic mastectomy. Postoperative satisfaction with breasts, psychosocial, and sexual well-being scores were significantly higher in the BCT cohort, while physical well-being significantly favored the M + R cohort 480.2 ± 286.3 and 453.1 ± 392.7 days later, respectively. CONCLUSIONS: Relative to BCT, M + R was used to manage a broad range of TBRs. The relative importance of oncologic and surgical risk reduction, symmetry, and number of procedures can vary considerably and may limit the utility of TBR as a guide for deciding between BCT and M + R. Clinical Trial StatementThis study was registered with clinicaltrials.gov as "A Prospective Trial to Assess Tumor:Breast Ratio and Patient Satisfaction Following Lumpectomy Versus Mastectomy With Reconstruction", Identifier: NCT02216136.

RESUMEN

Nonsurgical vulvovaginal rejuvenation (NVR) is growing in popularity as a treatment for restoration of youthful female genitalia. Numerous radiofrequency (RF) and laser devices have entered the market claiming improvement in vaginal laxity and genitourinary syndrome of menopause. There is a paucity of evidence existing concerning the effectiveness of these devices for both pre- and postmenopausal women with laxity and/or atrophy at the histologic and clinical level. Therefore, the goal of this review is to scrutinize the peer-reviewed data on NVR with RF and laser devices, identify gaps in existing literature, and propose opportunities for further investigation.

RESUMEN

Mastopexy and mastopexy-augmentation are aesthetic breast surgeries that seek to create youthful, beautiful appearing breasts. Age, hormonal changes, or weight loss can lead to alterations that require addressing the skin envelope and breast parenchyma. Many surgical approaches have been described including periareolar, vertical, and Wise pattern techniques, but most modern mastopexies include manipulation of the breast parenchyma to improve the longevity of breast ptosis correction. Mesh support of the ptotic breast is an extension of this paradigm shift and seeks to restore the lost strength of the support structures of the breast. Despite initial controversy, single stage mastopexy-augmentation has been demonstrated to be a safe option for appropriately selected and informed patients who desire both correction of shape and volume. Revisions may still be necessary based on patient and surgeon goals for correction. Evolving technologies will likely continue to enhance the ability of aesthetic plastic surgeons to provide pleasing, durable correction of breast ptosis.

RESUMEN

BACKGROUND: Sexual health issues can be characterized by vaginal laxity (VL), sexual distress, and sexual dysfunction. The epidemiology of these issues in plastic surgery patients, and especially breast cancer survivors, remains poorly understood. OBJECTIVES: To prospectively assess sexual health issues in a plastic surgery patient population with and without breast cancer. METHODS: A prospective cohort study was created in our practice from June to August 2017 with administration of a survey including the vaginal laxity questionnaire (VLQ), female sexual distress scale-revised (FSDS-R), and female sexual function index (FSFI). Multivariate logistic regression identified the controlled effect of patient variables on development of sexual health issues. RESULTS: Of 291 patients solicited, 239 completed the survey (37.7% breast cancer survivors vs 62.3% without). Prevalence of VL was nearly 1 in 6 women. Of these, 46.0% met criteria for sexual distress (FSDS-R ≥ 11.0) and 64.8% had sexual dysfunction (FSFI ≤ 26.5). Breast cancer survivors exhibited significantly greater overall sexual dysfunction (P < 0.001) and greater dysfunction within all FSFI domains of desire, arousal, lubrication, orgasm, satisfaction, and pain (all P < 0.02). On multivariate regression, number of vaginal deliveries predicted development of VL (OR 1.87, P < 0.001), presence of VL predicted sexual distress (OR 3.01, P = 0.007), while history of breast cancer predicted sexual dysfunction (OR 1.87, P < 0.05). CONCLUSIONS: Sexual health issues are prevalent amongst plastic surgery patients. Aesthetic practices can improve patients' quality of life by focusing on these areas. Potential therapeutic options to address sexual health issues should consider addressing vaginal laxity.

RESUMEN

BACKGROUND: Implant-based breast reconstruction (IBR) after nipple-sparing mastectomies (NSM) can have complications that require explantation of a tissue expander or permanent prosthesis. When complications occur, preservation of the nipple-areola complex (NAC) remains critical to ensure aesthetic breast reconstruction. To date, there are minimal data on outcomes for patients experiencing unplanned explantations in IBR after NSM. OBJECTIVES: To evaluate final reconstructive outcomes for NSM patients who undergo IBR and have an unplanned explanation and to separately analyze the outcome of the NAC aesthetic subunit. METHODS: We analyzed a prospectively maintained database of NSM patients undergoing IBR reconstruction at a single institution to identify patients who had complications resulting in unplanned explanation. Demographics, covariates, and reconstructive outcomes, including salvage with IBR or autologous flaps, were assessed. Final outcomes of the NAC were also evaluated. RESULTS: A total of 213 patients underwent 382 NSM with IBR with either direct-to-implant (DTI) or tissue expander/implant (TE/I) reconstructions. The complication rate was 15.2% (N = 58) and 33 (8.6%) unplanned explantations occurred: 23 (69.8%) of whom ultimately completed reconstruction with either IBR (30.4%) or autologous flaps (69.6%). NACs were preserved in 62.5% of breasts with unplanned explantations. Only 8 NACs were lost in the entire cohort (2.1%). CONCLUSIONS: Following unplanned explantations in IBR after NSM, salvage can be performed with either IBR or autologous flaps. However, the majority of salvage procedures in IBR after NSM will be with autologous flaps that bring in healthy soft tissue to restore location specific defects caused by complications. The NAC can ultimately be preserved as an aesthetic subunit in most patients despite the occurrence of initial complications.

RESUMEN

BACKGROUND: The ability to perform nonsurgical facial rejuvenation procedures is a core competency requirement for plastic surgery residents. However, limited data exist on training models to achieve competency in nonsurgical facial rejuvenation and on outcomes of these procedures performed by residents. The purpose here is to evaluate patient-reported outcomes and safety of nonsurgical facial rejuvenation procedures performed by plastic surgery residents. METHODS: We prospectively enrolled 50 patients undergoing neuromodulator and/or soft-tissue filler injections in a resident cosmetic clinic between April and August 2016. Patients completed FACE-Q modules pre-procedure, and at 1 week and 1 month post-procedure. Paired t-tests were used to calculate statistical significance of changes between pre- and post-procedure scores. Effect sizes were calculated to assess clinical improvement from pre- to post-procedure. The magnitude of change was interpreted using Cohen's arbitrary criteria (small 0.20, moderate 0.50, large 0.80). RESULTS: Forty-five patients completed the study. Patients experienced significant improvements (p < 0.001) in all FACE-Q domains, including aging appearance appraisal (improved from 49.7 ± 29.4 to 70.1 ± 21.6, effect size 0.79), psychological well-being (44.0 ± 14.6-78.6 ± 20.7, effect size 1.93), social functioning (48.6 ± 16.6-75.5 ± 21.7, effect size 1.20), and satisfaction with facial appearance (50.1 ± 13.7-66.2 ± 19.7, effect size 0.95). At 1 month, overall satisfaction with outcome and decision were 75.8 ± 20.7 and 81.1 ± 20.4, respectively. No patients experienced complications. CONCLUSIONS: Nonsurgical facial rejuvenation procedures performed by residents can improve patients' quality of life and provide high satisfaction without compromising safety.

RESUMEN

Background: Direct-to-implant (DTI) and tissue expander/implant (TE/I) reconstructions are the most common implant-based reconstructions after nipple-sparing mastectomy (NSM). However, there are little data beyond complication rates comparing these options. Fat grafting has emerged as an adjunct in NSM reconstructions to improve aesthetic results; however, its impact on patient perceptions of aesthetic outcomes remain unknown. To improve patient-centered care, aesthetic outcomes must be considered from the patients' perspective. Objectives: To evaluate patient-reported outcomes of aesthetic satisfaction and quality of life in patients undergoing immediate DTI vs TE/I reconstruction after NSM and to assess the role of fat grafting on these outcomes. Methods: This is a prospective cohort study comparing NSM patients undergoing DTI or TE/I reconstruction. Patient-reported outcomes were evaluated using the BREAST-Q. Continuous and categorical variables were analyzed using t test and Fisher's exact test, respectively. Results: Fifty-nine patients underwent 113 reconstructions with either DTI (n = 41) or TE/I (n = 18). Mean follow up was 12.1 months. DTI and TE/I patients had comparable satisfaction with outcome, though TE/I patients had significantly larger final implant sizes. TE/I who underwent fat grafting also had significantly higher satisfaction with outcome and psychosocial wellbeing. Conclusions: Patient-reported outcomes are comparable between DTI and TE/I reconstructions after NSM. In order for TE/I patients to achieve a similar level of satisfaction, they may require a larger final implant and additional operations compared to DTI patients. Additionally, fat grafting improves overall satisfaction. TE/I patients may have different aesthetic expectations than DTI patients, emphasizing patient-centered discussions are essential to optimizing outcomes after NSM. Level of Evidence: 3.

RESUMEN

BACKGROUND: Tissue liquefaction technology (TLT) delivers warmed saline from the liposuction cannula tip at low pressure pulses to disaggregate adipocytes. This technology differs significantly from that used in other liposuction devices including water jet-assisted liposuction. Here we introduce our early experience with this technology in the setting of fat transfer for revision breast reconstruction. METHODS: A retrospective chart review of 136 consecutive patients who underwent fat harvest with TLT and subsequent transfer into 237 breast reconstructions was conducted at a single institution. This two-surgeon series examined donor and recipient site complication rates over a median follow-up of 143 days [87-233]. RESULTS: The overall complication rate was 28.7 %, of which the majority (22.1 %) was fat necrosis at the recipient site as documented by any clinical, imaging, or pathologic evidence. The abdomen served as the donor site for half of the cases. Donor site complications were limited to widespread ecchymosis of the donor site notable in 10.4 % of cases. Twenty-five percent of patients had received postmastectomy radiotherapy prior to fat transfer. Prior to revision with fat transfer, implant-based breast reconstruction was used in 75.5 % of cases, and autologous flaps in the remainder. Fat transfer was combined with other reconstructive procedures 94.1 % of the time. CONCLUSIONS: TLT can be used to harvest adipocytes for fat transfer with donor site morbidity and recipient site complications comparable to other modalities. The efficiency and quality of harvested fat makes this technology appealing for wide spread adoption during fat transfer.

RESUMEN

BACKGROUND: Comprehensive aesthetic surgery education is an integral part of plastic surgery residency training. Recently, the ACGME increased minimum requirements for aesthetic procedures in residency. To expand aesthetic education and prepare residents for independent practice, our institution has supported a resident cosmetic clinic for over 25 years. OBJECTIVES: To evaluate the safety of procedures performed through a resident clinic by comparing outcomes to benchmarked national aesthetic surgery outcomes and to provide a model for resident clinics in academic plastic surgery institutions. METHODS: We identified a consecutive cohort of patients who underwent procedures through our resident cosmetic clinic between 2010 and 2015. Major complications, as defined by CosmetAssure database, were recorded and compared to published aesthetic surgery complication rates from the CosmetAssure database for outcomes benchmarking. Fisher's exact test was used to compare sample proportions. RESULTS: Two hundred and seventy-one new patients were evaluated and 112 patients (41.3%) booked surgery for 175 different aesthetic procedures. There were 55 breast, 19 head and neck, and 101 trunk or extremity aesthetic procedures performed. The median number of preoperative and postoperative visits was 2 and 4 respectively with a mean follow-up time of 35 weeks. There were 3 major complications (2 hematomas and 1 infection requiring IV antibiotics) with an overall complication rate of 1.7% compared to 2.0% for patients in the CosmetAssure database (P = .45). CONCLUSIONS: Surgical outcomes for procedures performed through a resident cosmetic clinic are comparable to national outcomes for aesthetic surgery procedures, suggesting this experience can enhance comprehensive aesthetic surgery education without compromising patient safety or quality of care. LEVEL OF EVIDENCE: 4 Risk.

RESUMEN

OBJECTIVE: The study purpose was to evaluate the associations between patient characteristics and the histologic remodeling scores of acellular dermal matrices (ADMs) biopsied from breast reconstruction sites in the first attempt to generate a multivariable risk prediction model of nonconstructive remodeling. It was hypothesized that host characteristics and surgical site assessments predict the degree of graft remodeling for ADMs used during breast reconstruction. METHODS: The ADMs were biopsied from the breast reconstruction sites of n = 62 patients during a subsequent breast procedure, stained with hematoxylin-eosin, and evaluated according to a semi-quantitative scoring system for remodeling characteristics (cell types, cell infiltration, extracellular matrix deposition, scaffold degradation, fibrous encapsulation, and neovascularization) and a mean composite score. Biopsies were stained with Sirius Red and Fast Green, and analyzed to determine the collagen I:III ratio. Based on univariate analyses between subject clinical characteristics and the histologic remodeling scores, cohort variables were selected for multivariable regression models using a P value of 0.20 or less. RESULTS: The composite score model yielded 3 variables: pack-year history, corticosteroid use, and radiation timing (r pseudo = 0.81). The model for collagen I yielded 2 variables: corticosteroid use and reason for reoperation (r pseudo = 0.78). The model for collagen III yielded 1 variable: reason for reoperation (r pseudo = 0.35). CONCLUSIONS: These preliminary results constitute the first steps in generating a risk prediction model that predicts the patients and clinical circumstances most likely to experience nonconstructive remodeling of biologic grafts used to reconstruct the breast.

RESUMEN

BACKGROUND: Subclinical infections, manifest as biofilms, are considered an important cause of capsular contracture. Acellular dermal matrices (ADMs) are frequently used in revision surgery to prevent recurrent capsular contractures. OBJECTIVE: We sought to identify an association between capsular contracture and biofilm formation on breast prostheses, capsules, and ADMs in a tissue expander/implant (TE/I) exchange clinical paradigm. METHODS: Biopsies of the prosthesis, capsule, and ADM from patients (N = 26) undergoing TE/I exchange for permanent breast implant were evaluated for subclinical infection. Capsular contracture was quantified with Baker Grade and intramammary pressure. Biofilm formation was evaluated with specialized cultures, rtPCR, bacterial taxonomy, live:dead staining, and scanning electron microscopy (SEM). Collagen distribution, capsular histology, and ADM remodeling were quantified following fluorescent and light microscopy. RESULTS: Prosthetic devices were implanted from 91 to 1115 days. Intramammary pressure increased with Baker Grade. Of 26 patients evaluated, one patient had a positive culture and one patient demonstrated convincing evidence of biofilm morphology on SEM. Following PCR amplification 5 samples randomly selected for 16S rRNA gene sequencing demonstrated an abundance of suborder Micrococcineae, consistent with contamination. CONCLUSIONS: Our data suggest that bacterial biofilms likely contribute to a proportion, but not all diagnosed capsular contractures. Biofilm formation does not appear to differ significantly between ADMs or capsules. While capsular contracture remains an incompletely understood but common problem in breast implant surgery, advances in imaging, diagnostic, and molecular techniques can now provide more sophisticated insights into the pathophysiology of capsular contracture. LEVEL OF EVIDENCE: 4 Therapeutic.

RESUMEN

BACKGROUND: Breast implants are the most commonly used medical devices in plastic surgery, and capsular contracture (CC) is one of the most common complications. However, our assessment of CC is based largely on Baker grade, which is problematically subjective and affords only four possible values. METHODS: The authors performed a systematic review concluding in September of 2021 in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. It identified 19 articles that propose approaches to measuring CC. RESULTS: In addition to Baker grade, the authors identified several modalities reported to measure CC. These included magnetic resonance imaging, ultrasonography, sonoelastography, mammacompliance measuring devices, applanation tonometry, histologic evaluation, and serology. Capsule thickness and other measures of CC inconsistently correlated with Baker grade, whereas the presence of synovial metaplasia was consistently associated with Baker grade I and II, but not III and IV capsules. CONCLUSIONS: There remains no particular method to reliably and specifically measure the contracture of capsules that form around breast implants. As such, we would recommend that research investigators use more than one modality to measure CC. Other variables that can impact breast implant stiffness and associated discomfort beyond CC need to be considered when evaluating patient outcomes. Given the value placed on CC outcomes in assessing breast implant safety, and the prevalence of breast implants overall, the need for a more reliable approach to measuring this outcome persists.

RESUMEN

BACKGROUND: Coronavirus disease of 2019 (COVID-19) poses unique challenges for breast reconstruction. At the authors' institution, COVID-19 postoperative protocols mandated patients undergoing immediate prosthetic breast reconstruction transition from 23-hour postoperative observation to same-day discharge. The authors sought to compare complications and hospital costs between these groups. METHODS: A retrospective study of consecutive patients who underwent immediate prosthetic breast reconstruction from March of 2019 to April of 2021 at an academic hospital was performed. Before mid-March of 2020, patients were admitted postoperatively for observation; after mid-March of 2020, patients were discharged the same day. Postoperative complications at 48 hours, 30 days, and 90 days and hospital costs were compared. RESULTS: There were 238 patients included (119 outpatient and 119 observation). Across all time points, total complications, major complications, categorical complications (wound healing, seroma, hematoma, infection, implant exposure), and reconstructive failures were low and not statistically different between groups. There were no differences in 30-day hospital readmission/reoperation rates (7.6% outpatient versus 9.2% observation; P = 0.640). No patient or surgical factors predicted major complication or hematoma by 48 hours or infection by 90 days. At 90 days, radiation history ( P = 0.002) and smoking ( P < 0.001) were significant predictors of major complications. Average patient care costs outside of surgery-specific costs were significantly lower for outpatients ($1509 versus $4045; P < 0.001). CONCLUSIONS: Complications after immediate prosthetic breast reconstruction are low. Outpatient surgery is safe, harboring no increased risk of complications. Furthermore, outpatient care is more cost-effective. Therefore, surgeons should consider outpatient management of these patients to minimize COVID-19 exposure and reduce resource consumption, all while maintaining excellent surgical care. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
