Using a Machine Learning Approach to Predict the Need for Elective Revision and Unplanned Surgery after Implant-based Breast Reconstruction.

Two-stage implant-based reconstruction after mastectomy may require secondary revision procedures to treat complications, correct defects, and improve aesthetic outcomes. Patients should be counseled on the possibility of additional procedures during the initial visit, but the likelihood of requiring another procedure is dependent on many patient- and surgeon-specific factors. This study aims to identify patient-specific factors and surgical techniques associated with higher rates of secondary procedures and offer a machine learning model to compute individualized assessments for preoperative counseling. A training set of 209 patients (406 breasts) who underwent two-stage alloplastic reconstruction was created, with 45.57% of breasts (185 of 406) requiring revisional or unplanned surgery. On multivariate analysis, hypertension, no tobacco use, and textured expander use corresponded to lower odds of additional surgery. In contrast, higher initial tissue expander volume, vertical radial incision, and larger nipple-inframammary fold distance conferred higher odds of additional surgery. The neural network model trained on clinically significant variables achieved the highest collective performance metrics, with ROC AUC of 0.74, sensitivity of 84.2, specificity of 63.6, and accuracy of 62.1. The proposed machine learning model trained on a single surgeon's data offers a precise and reliable tool to assess an individual patient's risk of secondary procedures. Machine learning models enable physicians to tailor surgical planning and empower patients to make informed decisions aligned with their lifestyle and preferences. The utilization of this technology is especially applicable to plastic surgery, where outcomes are subject to a variety of patient-specific factors and surgeon practices, including threshold to perform secondary procedures.

Effectiveness of SCAR-Q for assessment of incisional SCAR after implant-based reconstruction in breast cancer patients: Can it be a tool for incision selection?

Incisional scarring is a factor of cosmetic appearance evaluated after breast reconstruction, along with the shape, position, and size of the breast. This study aimed to examine the effect of the incision scar location on patient satisfaction after breast reconstruction. Using the Japanese version of the SCAR-Q, we assessed the scar appearance, symptoms and psychosocial effects. Plastic surgeons performed assessments using the Manchester Scar Scale. The patients were divided into two groups: those with scars on the margins of the breast (MB group) and those with scars in the breast area (IB group). The results revealed that patients in the MB group reported significantly higher satisfaction with the scar appearance and psychological impact than those in the IB group. However, assessments using the Manchester Scar Scale did not reveal any significant differences between the two groups. In conclusion, this study underscores the importance of patient-reported outcomes in the evaluation of scar satisfaction after breast reconstruction. Patients tend to prefer and have higher satisfaction with scars along the breast margin, which offers valuable insights into surgical decisions. Further studies with larger and more diverse sample sizes are required for validation.

Upper Limb Reconstruction with Latissimus Dorsi Flap

The latissimus dorsi flap (LDF) is a surgical technique used by surgeons to rebuild many different types of breast cancer surgical defects, such as modified radical mastectomy, quadrantectomy, and lumpectomy. The LDF can be utilized as an autogenous flap alone, in conjunction with implant-based immediate reconstruction, in conjunction with tissue expanders for a phased reconstruction, or in either case, either immediately or later. During breast reconstruction, the LDF is a dependable soft tissue covering option that offers shape and function with manageable short- and long-term morbidities. When tissue is scarce, the LDF can help by providing tissue volume in autologous reconstruction. It can also serve as a dependable vascular pedicle for implant-based repair in situations when the tissue has been exposed to radiation.

Co-surgeon versus Single-surgeon Outcomes in Free Tissue Breast Reconstruction: A Meta-analysis.

Autologous breast reconstruction offers superior long-term patient reported outcomes compared with implant-based reconstruction. Universal adoption of free tissue transfer has been hindered by procedural complexity and long operative time with microsurgery. In many specialties, co-surgeon (CS) approaches are reported to decrease operative time while improving surgical outcomes. This systematic review and meta-analysis synthesizes the available literature to evaluate the potential benefit of a CS approach in autologous free tissue breast reconstruction versus single-surgeon (SS). A systematic review and meta-analysis was conducted using PubMed, Embase, and MEDLINE from inception to December 2022. Published reports comparing CS to SS approaches in uni- and bilateral autologous breast reconstruction were identified. Primary outcomes included operative time, postoperative outcomes, processes of care, and financial impact. Risk of bias was assessed and outcomes were characterized with effect sizes. Eight retrospective studies reporting on 9,425 patients were included. Compared with SS, CS approach was associated with a significantly shorter operative time (SMD -0.65, 95% confidence interval [CI] -1.01 to -0.29, p < 0.001), with the largest effect size in bilateral reconstructions (standardized mean difference [SMD] -1.02, 95% CI -1.37 to -0.67, p < 0.00001). CS was also associated with a significant decrease in length of hospitalization (SMD -0.39, 95% CI -0.71 to -0.07, p = 0.02). Odds of flap failure or surgical complications including surgical site infection, hematoma, fat necrosis, and reexploration were not significantly different. CS free tissue breast reconstruction significantly shortens operative time and length of hospitalization compared with SS approaches without compromising postoperative outcomes. Further research should model processes and financial viability of its adoption in a variety of health care models.

Exosomes from Adipose-Tissue-Derived Stem Cells Induce Proapoptotic Gene Expression in Breast Tumor Cell Line.

Lipofilling is an option for breast reconstruction after tumor resection to avoid the complications of an implant-based reconstruction. Although some concerns exist regarding the oncological safety of tissue rich in mesenchymal stem cells with their proangiogenic and proliferation-supportive properties, there are also reports that adipose-tissue-derived stem cells can exhibit antitumoral properties. We isolated primary adipose-tissue-derived stem cells. Both conditioned medium and exosomes were harvested from the cell culture and used to treat the breast cancer cell line MCF-7. Cell viability, cytotoxicity, and gene expression of MCF-7 cells in response to the indirect co-culture were evaluated. MCF-7 cells incubated with exosomes from adipose-tissue-derived stem cells show reduced cell viability in comparison to MCF-7 cells incubated with adipose-tissue-derived stem-cell-conditioned medium. Expression of proapoptotic genes was upregulated, and expression of antiapoptotic genes was downregulated. The debate about the oncological safety of autologous fat grafting after tumor resection continues. Here, we show that exosomes from adipose-tissue-derived stem cells exhibit some antitumoral properties on breast cancer cell line MCF-7.

Evaluation of conventional IMRT and VMAT strategies for postmastectomy radiation therapy after immediate implant-based reconstruction using the new ESTRO-ACROP contouring guidelines.

This study evaluated the usability of conventional templates based on the new contour guidelines of the European Society of Radiation and Oncology and Advisory Committee in Radiation Oncology Practice (ESTRO-ACROP) for treatment plans of postmastectomy radiotherapy after immediate implant-based reconstruction. Intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) plans generated with two different treatment planning systems (TPSs, Eclipse and Monaco) were examined. Six computed tomography scans of patients aged 35-54years were retrospectively analysed who had undergone mastectomy and breast reconstruction using silicone implants after being diagnosed with left breast cancer. Six radiation oncologists participated in this study, and each of them contoured the target volume of one left breast using conventional contour (CTV-CONV) and new contour (CTV-ESTRO) methods. This study showed that compared with CTV-CONV, using CTV-ESTRO with objectives and cost functions similar to those of TPSs worsened the target volume coverage and increased the total number of monitor units. Considering the organs at risk, CTV-ESTRO tended to increase the mean dose delivered to the contralateral lung. It is concluded that the approach used for the new ESTRO-ACROP contour method cannot be applied in a manner similar to that for the conventional breast contour method, implying that the new ESTRO-ACROP contour method may require more time for improving plans for a given treatment.

Post-mastectomy Breast Reconstruction With Gas vs Saline Tissue Expanders: Does the Fill Type Matter?

The most common reconstruction technique following mastectomy is a two-stage technique that involves tissue expansion followed by definitive implant-based reconstruction (IBR). Tissue expanders (TEs) have classically used saline for initial fill; however, TEs with an initial gas fill (GTE) - including the CO2-based AeroForm TE and TEs initially filled with atmospheric air - have been increasingly used in the past decade. We aim to compare the outcomes in breast reconstruction for tissue expanders initially filled with saline vs. gas. PubMed was queried for studies comparing gas and saline-filled tissue expanders (STEs) used in IBR. A meta-analysis was performed on major postoperative outcomes and the required expansion and definitive reconstruction time. Eleven studies were selected and included in the analysis. No significant differences existed between tissue expansion with GTEs versus STEs for eleven of the thirteen postoperative outcomes investigated. Out of the complications investigated, only the risk of infection/cellulitis/abscess formation was significantly lower in the GTE cohort (OR = 0.62; 95% CI = 0.47 to 0.82; P = 0.0009). The time to definitive reconstruction was also significantly lower in the GTE cohort (MD = -45.85 days; 95% CI = -57.80 to -33.90; P < 0.00001). The total time to full expansion approached significance in the GTE cohort (MD = -20.33 days; 95% CI = -41.71 to 1.04; P = 0.06). A cost analysis considering TE cost and infection risk determined that GTE use saved a predicted $2,055.34 in overall healthcare costs. Surgical outcomes for both fill types are predominantly similar; however, GTEs were associated with a significantly decreased risk of postoperative infection compared to saline filled TEs. GTEs can also reduce healthcare expenditures and require less time until definitive reconstruction after placement.

Breast Reconstruction: Focus on Implant-Based Reconstruction

Autologous tissue-based reconstruction and prosthetic implant-based reconstruction are the two main categories of breast reconstruction. The natural feel, size, and form of the breast can be restored by breast reconstruction with breast implants. Following a nipple- and skin-sparing mastectomy and a modified radical mastectomy, implant-based breast reconstruction is most readily executed. The most popular technique for immediate and delayed postmastectomy breast reconstruction is implant breast reconstruction, which makes use of silicone tissue expanders, which were initially utilized for breast reconstruction by Radovan in 1978 and Austad in 1979. As a sign of femininity, breasts might be lost, which can cause a woman great psychological discomfort and negatively impact her sexual life and self-image. Women are given the choice of breast reconstruction following a breast cancer removal treatment, which can enhance their quality of life. However, implant-based reconstruction ought not to be seen as an adjuvant treatment. Procedures like skin-sparing mastectomy and nipple-areola-sparing mastectomy, which enable conservative surgery with an instant implant breast reconstruction, can only be carried out with an early diagnosis.

Impact of autologous breast reconstruction on bra fit.

To inform bra design by analyzing 3D surface images of breast cancer patients who underwent autologous breast reconstruction. We computed bra design measurements on 3D surface images of patients who underwent unilateral and bilateral autologous breast reconstruction. Breast measurements and right-left symmetry between preoperative baseline and postoperative time points were compared using either paired Student t-test or Wilcoxon signed-rank test, depending on the data's distribution. Regression analysis determined associations between measurements and patient characteristics such as age. Postoperative measurements and symmetry differences were also compared between autologous and implant-based breast reconstruction. Among participants who underwent bilateral autologous breast reconstruction, the reconstructed breasts were smaller and positioned higher on the chest wall than their native breasts. For patients who underwent unilateral reconstruction, similar postoperative changes were observed in the contralateral breast due to symmetry procedures. Overall, for participants whose baseline breast measurements showed substantial asymmetry, unilateral reconstruction decreased right-left asymmetry whereas bilateral reconstruction amplified right-left asymmetry. Preoperative baseline breast measurements, age, and BMI were statistically significantly associated with most postoperative breast measurements for participants who underwent bilateral autologous reconstruction. Compared to implant-based reconstruction, autologous reconstruction resulted in fewer changes in breast shape and symmetry that are pertinent to bra fit. Preoperative baseline breast measurements, age, and BMI can impact bra designs for breast cancer survivors who undergo autologous reconstruction due to size, shape, and symmetry changes. Bra needs of people who undergo autologous reconstruction differ from those who undergo implant-based reconstruction.

Incidence and Risk Assessment of Capsular Contracture in Breast Cancer Patients following Post-Mastectomy Radiotherapy and Implant-Based Reconstruction.

We retrospectively analyzed 118 women with breast cancer who underwent PMRT following an IBR between 2010 and 2022. Patients were treated with PMRT of 50.0-50.4 Gy in 25-28 fractions. Capsular contracture was categorized according to the Baker Classification for Reconstructed Breasts. After a median follow-up of 22 months, the incidence of clinically relevant capsular contracture (Baker III-IV) was 22.9%. Overall, capsular contracture (Baker I-IV) occurred in 56 patients (47.5%) after a median of 9 months after PMRT. The rate of reconstruction failure/implant loss was 25.4%. In the univariate analysis, postoperative complications (prolonged pain, prolonged wound healing, seroma and swelling) and regional nodal involvement were associated with higher rates of capsular contracture (p = 0.017, OR: 2.5, 95% CI: 1.2-5.3 and p = 0.031, respectively). None of the analyzed dosimetric factors or the implant position were associated with a higher risk for capsular contracture. Postoperative complications and regional nodal involvement were associated with an increased risk of capsular contracture following breast reconstruction and PMRT, while none of the analyzed dosimetric factors were linked to a higher incidence. Additional studies are needed to identify further potential risk factors.

The Impact of Breast Implant Cohesivity on Rippling and Revision Procedures in 2-Stage Prepectoral Breast Reconstruction

Abstract Background Rippling remains one of the most common complications following prepectoral implant-based reconstruction (IBR). Objectives The purpose of this study was to assess how implant cohesivity, a measure of elasticity and form stability, affects the incidence of rippling in prepectoral IBR. Methods We performed a retrospective cohort study of 2-stage prepectoral IBR performed between January 2020 and June 2022 at the Brigham and Women's Hospital and Dana-Farber Cancer Institute, comparing outcomes in patients who received Allergan Natrelle least cohesive, moderately cohesive, and most cohesive silicone gel implants. Outcomes of interest were rippling and reoperation for fat grafting. Results A total of 129 patients were identified, of whom 52 had the least cohesive implants, 24 had the moderately cohesive implants, and 53 patients had the most cohesive implants. The mean follow-up time was 463 (±220) days. A decreased incidence of rippling was seen with moderately cohesive (odds ratio [OR] 0.30, P &amp;lt; .05) and most cohesive (OR 0.39, P &amp;lt; .05) implants. Third stage reoperation for fat grafting was less frequent in patients with the most cohesive implant (OR 0.07, P &amp;lt; .05). In subgroup analyses, the patients with the most cohesive implant, who did not receive fat grafting at the time of initial implant placement, did not require reoperation for fat grafting (0%). Conclusions The use of highly cohesive implants in prepectoral IBR is associated with decreased rippling and fewer reoperations for fat grafting. Level of Evidence: 3

Bibliometric analysis of quality of life in implant-based breast reconstruction.

Implant-based breast reconstruction (IBR), following mastectomy, significantly impacts patients' quality of life (QoL), necessitating accurate measurement through psychometrically robust patient-reported outcome measure (PROM) tools. This bibliometric analysis aims to discern trends, identify gaps, and evaluate the use of such tools in the IBR literature. The 100 most cited publications regarding QoL in implant-based reconstruction were identified on Web of Science, across all available journal years (from 1977 to 2024) on 10 March 2024. Study details, including the citation count, main content focus, outcome measures, and usage of psychological questionnaires, were extracted and tabulated from each publication. The Oxford Centre for Evidence-Based Medicine (OCEBM) levels of evidence (LOE) of each study were assessed. The 100 most cited publications on QoL in implant-based reconstruction were identified, encompassing 64,192 patients and 28,114 reconstructed breasts. Citations per publication ranged from 62 to 457 (mean, 124.95 ± 73.05), with the highest-cited study being authored by Al-Ghazal (n = 457). The vast majority of publications were LOE II (n = 52), representative of prospective cohort studies, systematic reviews of non-randomised studies, and systematic review and meta-analysis. The number of publications for LOE V, IV, III, and I was 0, 7, 41, and 0, respectively. The main content focus was "quality of life" in 83 publications, with significant utilisation of the BREAST-Q questionnaire. A total of 80 publications used validated questionnaires with psychometric development. This analysis demonstrates that the research methodologies within IBR mostly consist of moderate-quality publications; however, notably, there was a lack of LOE I studies, underscoring a gap in high-quality research within the field. Moreover, only 62/100 used validated PROM tools. Future IBR research studies should be focussed on most robust methodologies, incorporating validated PROM tools, to optimise shared-decision making and informed consent.

Implant reconstruction after mastectomy–A review and summary of current literature

IntroductionThe landscape of breast reconstruction has changed significantly with a shift in focus to include the restoration of a patient's quality of life after cancer. Reconstructive options can be divided into alloplastic (implant based) and autologous (tissue based). This paper aims to provide a current educational summary regarding implant-based reconstruction after breast cancer surgery and review the current literature. MethodA review of the literature was conducted utilising standard PRISMA flowchart. Databases searched included Pubmed, EMBASE, and MEDLINE. ResultsCurrent practice is explored within the text, including types of implants, indications, and surgical approaches. Heterogenous cohorts, surgical technique variation, and selection bias can make comparison of the literature challenging. The major evidence reviews of implant-based reconstruction topics are discussed including, ADM use, radiotherapy, and complications. Despite the benefits of autologous reconstruction, implant-based techniques still represent a significant proportion of reconstructive breast procedures. However, implant-reconstruction is not without its risks and limitations and, with such variety in practice, there remains a lack of high-quality evidence guiding practice. Most importantly, patients need to be counselled about the pros and cons of each choice, particularly with the increasing utilisation of radiotherapy post-reconstruction. Ultimately, the patient and surgeon should reach a decision in full knowledge of the risks and potential outcomes. ConclusionsFurther research is required into implant-based reconstructive therapy, which will allow a greater consensus for management and a pathway for both surgeons and patients.

Progressive collapsing foot deformity: clinical presentation, diagnosis, and management options

Progressive collapsing foot deformity (PCFD) is a prevalent musculoskeletal disease that can cause significant deformity and disability. This review article aimed to overview the clinical presentation, diagnosis, and management options for PCFD. Google Scholar and PubMed were searched specifically for publications published up until May 2023 through several keywords. Inclusion criteria were articles on PCFD and articles published in English. The exclusion criteria were related to flexible flatfoot, vertical talus condition, and non-English articles. PCFD can present with various symptoms and signs, including elongation of the tibialis posterior tendon, hindfoot valgus deformity, forefoot abduction, weakness on the single-heel-rise test, and too-many-toes signs. The footprint assessment can be used easily and effectively to detect PCFD. Diagnosis of PCFD must be according to a thorough history taking, physical check-up, and appropriate imaging studies. Treatment options for PCFD range from conservative measures such as orthotic devices and physical therapy to more aggressive measures such as tendon transfers, arthroereisis, and implant-based reconstructions. The therapeutic plan should be individualized to the patient&amp;apos;s requirements and comorbidities. Different surgical modalities are available to manage flat foot deformity, including arthroereisis, lateral column lengthening, medializing calcaneal osteotomy, dorsal opening wedge osteotomy, and cotton osteotomy. Each intervention has its benefits and disadvantages, and the most appropriate modality should be selected according to the kind and severity of the deformity, the patient&amp;apos;s features and risk factors, and the surgeon&amp;apos;s experience. Pre- and postoperative patient-reported outcomes measurement information system scores can help to evaluate treatment outcomes.

Expanding the Use of Nipple-Sparing Mastectomies in Obese Patients Undergoing Staged Implant-Based Reconstruction

Expanding the Use of Nipple-Sparing Mastectomies in Obese Patients Undergoing Staged Implant-Based Reconstruction

Meshed Dermal Sling for Prepectoral Breast Reconstruction.

The best breast reconstruction solution after mastectomy remains a topic of wide debate. Recently, the focus in the field of implant-based reconstruction has been on the increasing indications for prepectoral reconstruction. This offers undoubted advantages over subpectoral reconstruction, ranging from better aesthetic results and patient comfort to a less invasive procedure that spares the pectoralis major muscle, reducing pain and postoperative recovery time. The dermal sling is a reconstructive variant introduced by Bostwick in the 1990s and is commonly used to complete the subpectoral pocket in one- or two-stage reconstruction, creating a dual-plane reconstruction. This method may be indicated after mastectomy for both therapeutic and prophylactic purposes. It can also be used for unilateral and bilateral reconstructions. We propose a new meshed dermal sling technique that allows complete prepectoral reconstruction without the use of acellular dermal matrix, thus reducing the cost of reconstruction. It also allows the indication for complete prepectoral reconstruction to be extended to patients with medium breast volume and grade 1 or 2 ptosis, without the need to use acellular dermal matrix or the pectoralis major muscle to complete the breast pocket.

Management of complications following implant-based breast reconstruction: a narrative review.

Complications associated with implant-based reconstruction have a spectrum of severity with sequelae ranging from mild aesthetic deformities to additional surgery, reconstructive failure and systemic illness. The purpose of this narrative review of the literature is to provide updated evidence-based information on the management of complications in implant-based reconstruction. A systematic search of PubMed, OVID MEDLINE and the Cochrane Library databases was performed to identify common complications associated with implant-based breast reconstruction, incidences of occurrence as well as preventative and management strategies. Pertinent short and long-term complications of implant-based breast reconstruction include hematoma, implant infection, seroma, skin envelope necrosis, capsular contracture, rupture, malposition, animation and contour deformities, implant-associated anaplastic large cell lymphoma, and breast implant illness. Important preventative measures for short term complications include meticulous sterile technique and antibiotic irrigation, adequate drainage and critical evaluation of mastectomy flaps. Management of short-term complications requires early recognition and aggressive treatment to prevent reconstructive failure as well as long-term complications such as capsular contracture. Important technological advances include dual-port expanders for seroma drainage, indocyanine green angiography for mastectomy flap perfusion evaluation, cohesive form-stable implants for treatment of rippling, and various biologic and synthetic mesh products for pocket control and correction. Important principles in management of short-term complications in implant-based reconstruction include aggressive and early intervention to maximize the chance of reconstructive salvage. Contemporary technological advances have played an important role in both prevention and treatment of complications. Over-arching principles in management of implant-based reconstruction complications focus on preventative techniques and preoperative patient counseling on potential risks, their likelihood, and necessary treatments to allow for informed and shared decision-making.

Moving the needle: a narrative review of enhanced recovery protocols in breast reconstruction.

After a relatively late introduction to the literature in 2015, enhanced recovery protocols for breast reconstruction have flourished into a wealth of reports. Many have since described unique methodologies making improved offerings with superior outcomes attainable. This is a particularly interesting procedure for the study of enhanced recovery as it encompasses two dissident approaches. Compared to implant-based reconstruction, autologous free-flap reconstruction has demonstrated superiority in a range of long-term metrics at the expense of historically increased peri-operative morbidity. This narrative review collates reports of recovery protocols for both approaches and examines methodologies surrounding the key pieces of a comprehensive pathway. All primary clinical reports specifically describing enhanced recovery protocols for implant-based and autologous breast reconstruction through 2022 were identified by systematic review of PubMed and Embase libraries. Twenty-five reports meeting criteria were identified, with ten additional reports included for narrative purpose. Included studies were examined for facets of innovation from the pre-hospital setting through outpatient follow-up. Notable findings were described in the context of a comprehensive framework with attention paid to clinical and basic scientific background. Considerations for implementation were additionally discussed. Of 35 included studies, 29 regarded autologous reconstruction with majority focus on reduction of peri-operative opioid requirements and length of stay. Six regarded implant-based reconstruction with most discussing pathways towards ambulatory procedures. Eighty percent of included studies were published after the 2017 consensus guidelines with many described innovations to this baseline. Pathways included considerations for pre-hospital, pre-operative, intra-operative, inpatient, and outpatient settings. Implant-based studies demonstrated that safe ambulatory care is accessible. Autologous studies demonstrated a trend towards discharge before post-operative day three and peri-operative opioid requirements equivalent to those of implant-based reconstructions. Study of enhanced recovery after breast reconstruction has inspired paradigm shift and pushed limits previously not thought to be attainable. These protocols should encompass a longitudinal care pathway with optimization through patient-centered approaches and multidisciplinary collaboration. This framework should represent standard of care and will serve to expand availability of all methods of breast reconstruction.

Current status prepectoral and subpectoral breast reconstruction in the USA.

Breast cancer remains the most commonly diagnosed cancer in women in the United States. In the setting of a mastectomy, implant-based reconstruction (IBR) remains the most common type of breast reconstruction performed. IBR is typically performed in two-stages (tissue expander - implant) or one stage [direct-to-implant (DTI)]. As a consequence of the limitations associated with submuscular placement of implants, prepectoral implant placement has been gaining more acceptance worldwide. The prepectoral plane eliminates the need for chest wall muscle dissection, disinsertion and manipulation avoiding the muscle related complications of the subpectoral approach such as increased pain, spasm and animation deformity. In addition, prepectoral placement shortens the recovery time and provides greater control of breast shape and contour. With the latest generation form-stable silicone implants coupled with the wide use and acceptance of acellular dermal matrices (ADMs) and other meshes to support the implant, this technique is becoming the mainstay of implant-based reconstruction, under these circumstances the subpectoral technique will continue to be the benchmark to which the prepectoral technique will be compared to. The authors sought to review the literature emanating from North America that pertains to this topic and provide an up-to-date assessment of the current practices of the prepectoral and submuscular technique.

Breast reconstruction after mastectomy in patients with obesity: a narrative review.

Breast reconstruction in patients with obesity presents numerous challenges, both in terms of surgical technique and post-operative complication management. As breast reconstruction techniques continue to evolve, the armamentarium of reconstructive options for patients with obesity has vastly expanded. Options now include immediate or delayed, implant-based, autologous, or hybrid reconstruction. Determining the optimal breast reconstruction in this complex population requires nuanced and experienced decision-making. A literature search was conducted to identify studies assessing breast reconstruction considerations in patients with obesity. The search was performed on PubMed and was limited to English language studies published between 1990 and 2023. Primary studies, case reports, chart reviews, and qualitative studies were included. Additional articles were identified for inclusion based on a review of references, as well as a web-based search, to identify additional studies that were not captured with the primary search strategy. This narrative review article summarizes the current literature available to guide surgeons in breast reconstruction in patients with obesity. The advancements in oncologic surgery and breast reconstruction techniques have expanded available surgical options, including immediate or delayed implant-based, autologous, or hybrid breast reconstruction. Each approach has its unique advantages, disadvantages, and surgical considerations. Despite the challenges, patients with obesity can achieve favorable aesthetic outcomes through careful assessment of comorbidities and expectation management.
