Breast Reconstruction: The Oncoplastic Approach.

Breast reconstruction surgery is continualladvancing, significantly enhancing patient well-being. Current surgical techniques prioritize minimizing donor site morbidity while achieving a more natural breast appearance. Increasing patient preferences for avoiding prosthetic materials in reconstruction, along with advancements in oncological safety and heightened aesthetic expectations, are driving the exploration and development of innovative approaches. Today's reconstructive options range from straightforward oncoplastic glandular remodeling to intricate microsurgical procedures. This narrative review, titled "Breast reconstruction: the oncoplastic approach," provides a comprehensive overview of contemporary trends in breast-conserving treatment. It evaluates the indications for these techniques and offers guidance to plastic surgeons in crafting personalized treatment plans. This approach presents a valuable single-stage alternative or adjunct to traditional prosthetic or microsurgical reconstruction methods.

Establishment and characterization of a rat model of scalp-cranial composite defect for multilayered tissue engineering.

Composite cranial defects have individual functional and aesthetic ramifications, as well as societal burden, while posing significant challenges for reconstructive surgeons. Single-stage composite reconstruction of these deformities entail complex surgeries that bear many short- and long-term risks and complications. Current research on composite scalp-cranial defects is sparse and one-dimensional, often focusing solely on bone or skin. Thus, there is an unmet need for a simple, clinically relevant composite defect model in rodents, where there is a challenge in averting healing of the skin component via secondary intention. By utilizing a customizable (3D-printed) wound obturator, the scalp wound can be rendered non-healing for a long period (more than 6 weeks), with the cranial defect patent. The wound obturator shows minimal biotoxicity and will not cause severe endocranium-granulation adhesion. This composite defect model effectively slowed the scalp healing process and preserved the cranial defect, embodying the characteristics of a "chronic composite defect". In parallel, an autologous reconstruction model was established as the positive control. This positive control exhibited reproducible healing of the skin within 3 weeks with variable degrees of osseointegration, consistent with clinical practice. Both models provide a stable platform for subsequent research not only for composite tissue engineering and scaffold design but also for mechanistic studies of composite tissue healing.

Propeller Perforator Flaps Used for Hand and Digit Reconstruction: A Systematic Review.

Background: Propeller perforator flaps (PPFs) have increased in popularity due to the freedom in design and ability to cover a variety of defects without sacrificing the major vessels. Present reports of PPFs for upper limb reconstruction have not provided guidance for hand reconstruction, specifically. This study aims to review the current literature and evaluate techniques for use of PPFs in hand reconstruction. Methods: A comprehensive literature review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for articles published from 1991 to 2021. The database search was queried for records using appropriate Medical Subject Headings (MeSH) terms. Studies reporting PPFs were limited to English language and excluded lower extremity or upper extremity reconstruction not specific to defects in the hand or digits. Study characteristics, patient demographics, indications, preoperative testing, flap characteristics, flap survival, and complication rates were collected. Results: Out of the initial 1,348 citations yielded, 71 underwent full-text review. Ultimately, 25 unique citations were included encompassing 12 retrospective reviews (48%), 3 prospective cohort studies (10%), and 10 case series (40%). In review, 525 patients underwent reconstruction with a total of 613 propeller flaps performed to repair defects of the hand, digits, or both with use of 18 unique flap types. Overall flap survival was 97.8%. Acute wounds accounted for 72.9% of performed reconstructions. The mean flap coverage was 14.7 cm2. Complications occurred in 19.8% of cases, with venous congestion and partial flap necrosis occurring in 5.5 and 6.5% of cases, respectively, leading to a flap failure rate of 2.1%. Conclusion: PPFs are a reliable option for hand or digital reconstruction, allowing surgeons to cover a variety of defects without sacrificing local vasculature. Despite nearly a 20% reported complication rate, nearly all flaps with venous congestion and partial flap necrosis included in these articles resolved without the need for secondary intervention, retaining an excellent overall flap survival.

Outcome of modified fleur-de-lis latissimus dorsi myocutaneous flap for breast reconstruction.

BACKGROUND: Reconstruction of breast following mastectomy is important in terms of rehabilitating patients of breast cancer. Numerous approaches have been used in the reconstruction process. A procedure that has gained interest of the patients is reconstruction of breast using the autologous form. Main objective of this study is to determine the outcomes of modified fleur-de-lis latissimus dorsi flap in patients undergoing breast reconstruction. METHODOLOGY: This is a retrospective case series which was conducted at the Department of Plastic Surgery, SIMS/Services Hospital, Lahore, from January 2020 till December 2022. 184 patients age 25-60 years and Females with a history of mastectomy, who had to undergo creation of breast shape using a tissue flap from another part of the body at the site of breast following mastectomy were included. All patients were subjected to standard procedure of breast reconstruction with latissimus dorsi flap using modified fleur-de-lis technique and postoperatively weekly assessment in the first month and then monthly until 3 months was carried out and outcome of the study was analysed. RESULTS: The mean age and VAS score of the patients was 49.7 ± 9.17 and 6 ± 2.21, respectively. 57.1 % patients have DCIS, benign in 38 % patients and other tumours were present in 4.9 % patients. Immediate versus delayed reconstruction was done in 63.6 % versus 36.4 % patients respectively. Good aesthetic outcome was achieved in 80.3 % patients CONCLUSION: Modified fleur-de-lis latissimus dorsi flap in patients undergoing breast reconstruction yielded a good aesthetic outcome in the majority of the patients.

Latissimus dorsi flap for breast reconstruction: a large single-institution evaluation of surgical outcome and complications.

PURPOSE: The use of autologous tissues is considered gold standard for patients undergoing breast reconstruction and is the preferred method in the post-radiation setting. Although the latissimus dorsi flap (LDF) has been replaced by abdominal flaps as technique of choice, it remains a valuable option in several specific clinical situations and its use has been regaining popularity in recent years. In this work, we present an 18-year retrospective analysis of a single-institution single-surgeon experience with LDF-based reconstruction with focus on early complications and reconstructive failures. METHODS: Hospital records of all patients undergoing breast surgery for any reason in the Certified Breast Cancer Center, Regio Klinikum Pinneberg, Germany between April, 1st 2005 and October, 31st 2022 were reviewed. 142 consecutive LDF-based reconstructive procedures were identified. Detailed information was gathered on patient characteristics, treatment-related factors, and complications. RESULTS: One hundred forty patients (139 female, 1 male) received 142 LDF-based surgeries. The flap was used mainly for immediate breast reconstruction with or without implant (83% of patients), followed by defect coverage after removal of a large tumor (7%), implant-to-flap conversion with or without placement of a new implant (6%), and delayed post-mastectomy reconstruction (4%). The use of LDF decreased between 2005 and 2020 (2005: 17, 2006: 13, 2007: 14, 2008: 16, 2009: 5, 2010: 9, 2011: 8, 2012: 3, 2013: 10, 2014: 8, 2015: 8, 2016: 7, 2017: 7, 2018: 4, 2019: 4, 2020: 2, 2021: 6, 2022: 4). Surgery was performed for invasive breast cancer in 78%, ductal carcinoma in situ in 20% and other reasons such as genetic mutation in 1% of patients. Ipsilateral radiation therapy was received by 12% of patients prior to LDF surgery and by 37% after the surgery. 25% of patients were smokers. The median duration of surgery, including all procedures conducted simultaneously such as e.g., mastectomy, axillary surgery, or implant placement, was 117 min (range 56-205). Patients stayed in the hospital for a median of 7 days (range 2-23 days). The most common complication was seroma (26%), followed by wound dehiscence (8%), surgical site infection (7%), partial skin and/or nipple necrosis of any size (7%) and hematoma requiring surgical evacuation (2%). 19% of all patients required seroma aspiration or drainage, mostly at the donor site and performed under ultrasound guidance in the ambulatory setting. Flap loss due to necrosis occurred in 2% of patients. CONCLUSIONS: Latissimus dorsi flap is a well-established surgical technique commonly used for immediate breast reconstruction as well as defect coverage in locally advanced breast cancer. To the best of our knowledge, this is one of the largest single-surgeon analyses of early complications in patients receiving LDF. As expected, seroma was the most common complication observed in nearly one third of patients and requiring a therapeutic intervention in every fifth patient. Serious adverse events occurred rarely, and flap loss rate was very low.

Pedicle stabilization with fibrin sealant in DIEP flap breast reconstruction.

Microsurgical procedures are nowadays routinely performed worldwide in reconstructive surgery. The deep inferior epigastric artery perforator (DIEP) flap has become the gold standard in breast reconstruction due to its excellent outcomes and lower donor site morbidity. However, complications, including flap failure, still occur in DIEP flap breast reconstruction. Often, according to our experience, these complications result from pedicle disorders, which can be attributed to postoperative mobilization. In the present study, we evaluated the efficacy and safety of using a fibrin sealant as a method for pedicle stabilization to prevent pedicle mobilization in the postoperative period. With our technique, after the flap insetting and microsurgical anastomosis, the pedicle was stabilized by applying a fibrin sealant (TISSEEL™) around and over the entire pedicle. Our study included a homogeneous series of 70 patients who received a delayed DIEP flap breast reconstruction. A retrospective study was conducted to evaluate this novel technique compared to the conventional method. In our experience, the fibrin glue allowed us to reduce the strain for correct pedicle positioning and all subsequent efforts to avoid displacements in the postoperative period. Our preliminary results suggest that this method may lead to a reduction in overall complications attributable to pedicle disorders.

Imaging of the Reconstructed Breast.

The incidence of breast cancer and, therefore, the need for breast reconstruction are expected to increase. The many reconstructive options available and the changing aspects of the field make this a complex area of plastic surgery, requiring knowledge and expertise. Two major types of breast reconstruction can be distinguished: breast implants and autologous flaps. Both present advantages and disadvantages. Autologous fat grafting is also commonly used. MRI is the modality of choice for evaluating breast reconstruction. Knowledge of the type of reconstruction is preferable to provide the maximum amount of pertinent information and avoid false positives. Early complications include seroma, hematoma, and infection. Late complications depend on the type of reconstruction. Implant rupture and implant capsular contracture are frequently encountered. Depending on the implant type, specific MRI signs can be depicted. In the case of myocutaneous flap, fat necrosis, fibrosis, and vascular compromise represent the most common complications. Late cancer recurrence is much less common. Rarely reported late complications include breast-implant-associated large cell anaplastic lymphoma (BIA-ALCL) and, recently described and even rarer, breast-implant-associated squamous cell carcinoma (BIA-SCC). In this review article, the various types of breast reconstruction will be presented, with emphasis on pertinent imaging findings and complications.

Radiation and free flaps: what is the optimal timing?

The debate over when to perform flaps in patients undergoing radiation remains an ongoing dilemma without definitive resolution. Classically, reconstructive surgeons recommended avoiding exposure of autologous flaps to radiotherapy due to concerns over surgical complications and poor aesthetic outcomes. However, delayed reconstruction carries its own risk profile and aesthetic limitations, given the irreversible changes to the breast envelope. Immediate reconstruction not only confers psychosocial benefits but allows for preservation of the native breast skin and footprint. In recent years, a growing body of evidence suggests that with modern radiation techniques, long-term outcomes of immediate vs. delayed autologous reconstruction may be more similar than previously thought. This review examines the advantages and disadvantages of each treatment algorithm and critically evaluates the existing literature on autologous breast reconstruction in the setting of post-mastectomy radiotherapy. Importantly, radiation regimens have varied widely over time and between institutions, introducing significant heterogeneity in published outcomes of flap contracture or fat necrosis after immediate reconstruction. While delayed autologous reconstruction remains a reasonable pathway, the benefits of immediate reconstruction should not be dismissed. Our findings ultimately corroborate the view that immediate flap reconstruction is a sound treatment option that can be safely offered to patients. The decision regarding which pathway to pursue should ultimately be patient-centric and driven by multidisciplinary consensus, rather than by prior dogma.

Psychological impact of the COVID-19 pandemic on breast cancer patients.

PURPOSE: The COVID-19 pandemic uniquely impacted patients with breast cancer as mastectomies were allowed to proceed, yet breast reconstruction surgeries were halted. The purpose of this study was to examine the effect of the COVID-19 pandemic on the rates of breast reconstruction and patients' well-being. METHODS: A chart review included all patients who underwent mastectomy from December 2019 to September 2021. Patients were contacted by a member of the research team and asked to participate in a COVID-19-specific survey and to complete the Hospital Anxiety and Depression Scale (HADS). Patients were then grouped into "surge" or "nonsurge" groups based on the date of mastectomy. RESULTS: Two hundred and fifty-nine patients were included in this study. During the study period, 42% (n = 111) of the patients underwent breast reconstruction. The "surge" group included 106 patients whereas the "nonsurge" group included 153 patients. Fewer patients began breast reconstruction during the surge period compared with the nonsurge period (34.0% vs. 49.0%, p = 0.017). Eighty-six patients participated in the COVID-19 survey. Forty-one percent (n = 35) of the patients felt that their care was disrupted because of COVID-19. Eighty-three patients completed the HADS survey. Overall, 16.8% and 15.7% of the respondents fell into the moderate to severe ranges for both anxiety and depression scales, respectively. CONCLUSIONS: Patients with breast cancer have faced increased difficulties with access to breast reconstruction throughout the COVID-19 pandemic. Our institution demonstrated decreased rates of breast reconstruction and an increase in anxiety and depression. The positive benefits of breast reconstruction cannot be overlooked when determining resource allocation in the future.

Surgical Management of Breast Amyloidosis.

Amyloidosis is characterized by extracellular deposition of insoluble misfolded beta-pleated proteins. Amyloid disease involving the breast is rare and there is a paucity of literature guiding surgical management in caring for these patients. In this article we review medical and surgical management with an emphasis on post mastectomy breast reconstruction. We propose an algorithm for breast reconstructive options based on unique considerations in this patient population. An institutional database at the Medical College of Wisconsin was used to identify patients diagnosed with breast amyloidosis from 2011 to 2021. We utilized the electronic medical record to present patient demographics, diagnostic and treatment data regarding the medical and surgical management of these patients. Five women were identified with a median age of 70 years and a median follow up of 19 months (range, 9-80 months). All patients were diagnosed with light chain (AL) type of amyloidosis. Systemic amyloidosis was identified in 3 patients and localized disease was identified in 2 patients. Concurrent breast malignancy was identified in 2 patients who underwent skin-sparing mastectomies followed by breast reconstruction with both prosthetic and autologous techniques. Both prosthetic and autologous reconstructive techniques are safe in patients with amyloidosis, however careful consideration and preoperative work-up are warranted to avoid complications in this vulnerable population. Further studies are warranted to improve surgical outcomes in patients with amyloidosis involving the breast.

Maximizing volume in autologous breast reconstruction: stacked/conjoined free flaps.

Since the first report of abdominally based tissue breast reconstruction with a free flap of rectus abdominis muscle to reconstruct mastectomy defects, autologous breast reconstruction has continually increased in popularity due to improved cosmesis, patient satisfaction, and quality of life. While abdominal tissue is frequently used as the principal donor site, other flap options are available, including from the buttocks, thighs, and back. Microsurgical advancements in recent years have continued to improve patient outcomes and decrease operative times. One innovative technique is the use of stacked or conjoined free flaps which can be used when more breast volume is needed than can be provided by one free flap alone. These stacked or conjoined free flaps can be used unilaterally or bilaterally and can include combinations of nearly every free flap depending on the volume of tissue desired for the reconstruction. Though these flaps are increasing in popularity, there is limited comparative data on the safety and efficacy of stacked or conjoined free flaps as compared to single free flaps. In this review, we aim to highlight the use of stacked/conjoined free flaps for autologous breast reconstruction, as well as highlight recent data on this technique and provide recommendations for its safe use.

Total breast reconstruction with a fat-augmented latissimus dorsi flap: A comparative study between muscle and myocutaneous flaps.

The fat-augmented latissimus dorsi myocutaneous flap can overcome the volume insufficiency of latissimus dorsi flaps by immediate fat grafting into the flap. When breast skin supplementation is unnecessary, latissimus dorsi flaps can be harvested as a muscle flap to avoid an additional back incision. Here, we compared the efficacy of fat-augmented latissimus dorsi myocutaneous and muscle flaps in total breast reconstruction. We retrospectively reviewed 94 cases of unilateral total breast reconstruction using fat-augmented latissimus dorsi flaps (muscle: 40, myocutaneous: 54) at our hospital from September 2017 to March 2022. The muscle flap group had a significantly shorter operative time than the myocutaneous flap group (p < 0.0001). Mastectomy specimen weight did not differ between the 2 groups, but total flap weight in the muscle flap group was significantly lower (p < 0.0001). Conversely, total fat graft volume, fat graft volume to the latissimus dorsi flap, and fat graft volume to the pectoralis major muscle were significantly greater in the muscle flap group (p < 0.0001, p < 0.0001, and p = 0.02, respectively). The percentage of cases requiring additional fat grafting was significantly higher in the muscle flap group, but postoperative esthetic evaluation did not significantly differ between the 2 groups. Both groups scored high on each BREAST-Q item, but the muscle flap group scored significantly higher for "Satisfaction with Back." Although the frequency of additional fat grafting was higher than with fat-augmented latissimus dorsi myocutaneous flaps, total breast reconstruction with fat-augmented latissimus dorsi muscle flaps is a viable technique with a short operative time and high patient satisfaction.

Breast reconstruction: Review of current autologous and implant-based techniques and long-term oncologic outcome.

Implant-based reconstruction is the most common method of breast reconstruction. Autologous breast reconstruction is an indispensable option for breast reconstruction demanding keen microsurgical skills and robust anatomical understanding. The reconstructive choice is made by the patient after a discussion with the plastic surgeon covering all the available options. Advantages and disadvantages of each technique along with long-term oncologic outcome are reviewed.

Obesity and the Latissimus Dorsi Flap: A Radiologic Study.

Introduction: The increasing prevalence of obesity in patients with breast cancer has prompted a reappraisal of the role of the latissimus dorsi flap (LDF) in breast reconstruction. Although the reliability of this flap in obese patients is well-documented, it is unclear whether sufficient volume can be achieved through a purely autologous reconstruction (eg, extended harvest of the subfascial fat layer). Additionally, the traditional combined autologous and prosthetic approach (LDF + expander/implant) is subject to increased implant-related complication rates related to flap thickness in obese patients. The purpose of this study is to provide data on the thicknesses of the various components of the latissimus flap and discuss the implications for breast reconstruction in patients with increasing body mass index (BMI). Methods: Measurements of back thickness in the usual donor site area of an LDF were obtained in 518 patients undergoing prone computed tomography-guided lung biopsies. Thicknesses of the soft tissue overall and of individual layers (e.g., muscle, subfascial fat) were obtained. Patient, demographics including age, gender, and BMI were obtained. Results: A range of BMI from 15.7 to 65.7 was observed. In females, total back thickness (skin, fat, muscle) ranged from 0.6 to 9.4 cm. Every 1-point increase in BMI resulted in an increase of flap thickness by 1.11 mm (adjusted R2 of 0.682, P < .001) and an increase in the thickness of the subfascial fat layer by 0.513 mm (adjusted R2 of 0.553, P < .001). Mean total thicknesses for each weight category were 1.0, 1.7, 2.4, 3.0, 3.6, and 4.5 cm in underweight, normal weight, overweight, and class I, II, III obese individuals, respectively. The average contribution of the subfascial fat layer to flap thickness was 8.2 mm (32%) overall and 3.4 mm (21%), 6.7 mm (29%), 9.0 mm (30%), 11.1 mm (32%), and 15.6 mm (35%) in normal weight, overweight, class I, II, III obese individuals, respectively. Conclusion: The above findings demonstrate that the thickness of the LDF overall and of the subfascial layer closely correlated with BMI. The contribution of the subfascial layer to overall flap thickness tends to increase as a percentage of overall flap thickness with increasing BMI, which is favourable for extended LDF harvests. Because this layer cannot be separated from overall thickness on examination, these results are useful in estimating the amount of additional volume obtained from an extended latissimus harvest technique.

Introduction: La prévalence croissante d'obésité chez les patientes atteintes du cancer du sein a suscité une réévaluation du rôle du lambeau du grand dorsal (LGD) en reconstruction mammaire. La fiabilité de ce lambeau est bien établie en cas d'obésité, mais on ne sait pas si le volume suffit pour effectuer une reconstruction purement autologue (p. ex., prélèvement élargi de la couche adipeuse sous-aponévrotique). De plus, en cas d'obésité, la combinaison habituelle de l'approche autologue et prothétique (LGD+expanseur et implant) est liée à un taux de complications plus élevé lié aux implants à cause de l'épaisseur du lambeau. La présente étude visait à obtenir des données sur l'épaisseur des diverses parties du grand dorsal et à traiter des conséquences de la reconstruction mammaire chez les patientes ayant un IMC plus élevé. Méthodologie: Les chercheurs ont mesuré l'épaisseur du dos au siège habituel de prélèvement du LGD chez 518 patientes dans le cadre d'une biopsie pulmonaire orientée par tomodensitométrie en position couchée. Ils ont mesuré l'épaisseur globale du dos et l'épaisseur de chaque couche dans cette région. Ils ont également obtenu les données démographiques des patientes, y compris l'âge, le genre et l'IMC. Résultats: Les chercheurs ont observé une fourchette d'IMC de 15,7 à 65,7. Chez les femmes, l'épaisseur totale du dos (peau, adiposité, muscle) variait entre 0,6 et 9,4 cm. Chaque point ajouté à l'IMC est associé à une augmentation de l'épaisseur du lambeau de 1,11 mm (rapport de cote rajusté [RCR] de 0,682, p<0,001) et à une augmentation de l'épaisseur de la couche adipeuse sous-aponévrotique de 0,513 mm (RCR de 0,553, p<0,001). L'épaisseur totale moyenne pour chaque catégorie de poids correspondait à 1,0, 1,7, 2,4, 3,0, 3,6 et 4, cm chez les patientes en insuffisance pondérale, de poids normal, en surpoids et obèses de classe I, II et III, respectivement. L'apport moyen de la couche adipeuse sous-aponévrotique à l'épaisseur du lambeau était de 8,2 mm (32 %) globalement et de 3,4 mm (21 %), 6,7 mm (29 %), 9,0 mm (30 %), 11,1 (32 %) et 15,6 mm (35 %) chez les patientes de poids normal, en surpoids et obèses de classe I, II, III, respectivement. Conclusion: Les résultats précédents démontrent que l'épaisseur globale du LGD et de la couche sous-aponévrotique est étroitement liée à l'IMC. L'apport de la couche sous-aponévrotique a tendance à être proportionnel à l'IMC en pourcentage de l'épaisseur globale du lambeau, ce qui est favorable à un prélèvement étendu du LGD. Puisque cette couche ne peut pas être séparée de l'épaisseur globale à l'examen, ces résultats sont utiles pour évaluer le volume supplémentaire obtenu à partir de la technique de prélèvement élargi du grand droit.

Preoperative Assessment of the Breast Reconstruction Patient.

Through a multidisciplinary approach, as well as, a nuanced appreciation of patient goals and setting appropriate expectations, breast reconstruction can significantly improve the quality of life following mastectomy. A thorough review of the patient medical and surgical history in addition to oncologic treatments will facilitate discussion and recommendations for an individualized shared decision-making reconstructive process. Alloplastic reconstruction, although a highly popular modality, has important limitations. On the contrary, autologous reconstruction is more flexible but requires more thorough consideration.

Hybrid Microsurgical Breast Reconstruction:: HyFIL® & HyPAD™ Techniques.

There are numerous indications for hybrid breast reconstruction, with the most common being patients who have inadequate donor site volume to achieve the desired breast volume. This article reviews all aspects of hybrid breast reconstruction, including preoperative and assessment, operative technique and considerations, and postoperative management.

Recent advances in surgical techniques for breast reconstruction.

Although the number of patients with breast cancer continues to rise worldwide, survival rates for these patients have significantly improved. As a result, breast cancer survivors are living longer, and quality of life after treatment is of increasing importance. Breast reconstruction is an important component that affects quality of life after breast cancer surgery. With the development of silicone gel implants in the 1960s, autologous tissue transfer in the 1970s, and tissue expanders in the 1980s, breast reconstruction has advanced over the decades. Furthermore, the advent of perforator flaps and introduction of fat grafting have rendered breast reconstruction a less invasive and more versatile procedure. This review provides an overview of recent advances in breast reconstruction techniques.

Delayed-immediate breast reconstruction: An assessment of complications and outcomes in the context of anticipated post-mastectomy radiotherapy.

INTRODUCTION: The detrimental effects of post-mastectomy radiotherapy on breast reconstruction are well known. We report our experience with a delayed-immediate approach involving an initial subcutaneous implant with definitive reconstruction after adjuvant radiotherapy. METHODS: Patients were identified retrospectively from hospital, theatre and implant registry records. Details regarding demographics, cancer pathology, surgical data and oncological therapies were collected. Primary outcomes included complication rates of first-stage surgery and time to definitive reconstruction. RESULTS: A total of 115 patients underwent mastectomy and temporary subcutaneous implant (36 nipple sparing) between 2008 and 2019. Five were smokers with eleven having a body mass index > 30. The median age was 46 years (27-76 years) and tumour size 50 mm. Almost 95% underwent radiotherapy, 82% chemotherapy and 70% had axillary node clearance. Median mastectomy weight was 464 g (123-1300 g) with median temporary implant volume 375 cc (180-655 cc). Complications of first-stage surgery at three months included 5.2% implant loss (n = 6), 14.8% infection rate, 17.4% readmission rate and 10.4% returned to theatre. Reconstructive failure occurred in four cases (3.5%). A total of 76 patients completed definitive reconstruction, including 26 autologous, 21 latissimus dorsi with implant, and 28 implant-only reconstructions. The median time to reconstruction following the completion of radiotherapy was 12 months. This increased in those who had implant complications (28 vs. 15 months) or radiotherapy (16 vs. 10 months) versus those without. CONCLUSIONS: Delayed-immediate breast reconstruction using a temporary subcutaneous implant has been shown to be a safe, feasible and potentially beneficial method than simple mastectomy and delayed reconstruction with a complication rate comparable to that of immediate implant reconstruction.
