RESUMO

BACKGROUND: Oncoplastic surgery is an expanding approach for managing breast conservation because it offers improved cosmetic outcomes while maintaining oncological safety. OBJECTIVES: This study aimed to assess the oncological and surgical outcomes of patients who underwent oncoplastic procedures at a single institution. METHODS: The study population includes all consecutive breast cancer patients who underwent lumpectomy followed by immediate oncoplastic breast reconstruction with contralateral breast adjustment between 2010 and 2021. Following IRB approval, patient demographics, tumor characteristics, surgical details, complications, and follow-up were evaluated for this group. Quality of life (QOL) and patient-reported outcome measures were assessed through questionnaires. RESULTS: Following multidisciplinary tumor board discussion, 77 patients (82 breasts) underwent oncoplastic surgery. Of these, 92.2% underwent breast MRI prior to surgery with mean mass enhancement of 2.35 cm (range, 0-8.5 cm) and non-mass enhancement of 5.77 cm (range, 0-14 cm), and 44% presented with multifocal disease. The final positive surgical margin rate was 2.4%, and all conserved breasts received adjuvant radiation therapy. The 5-year local recurrence rate for invasive tumors was 4.1%. QOL scores were generally high, with most patients reporting good to excellent cosmetic outcomes and high personal satisfaction with breast appearance and softness. Physicians reported breast symmetry in 89.5%. CONCLUSIONS: The findings suggest that oncoplastic surgery with contralateral breast adjustment is safe, effective, and an excellent option for breast cancer patients wishing for breast conservation even for large or multifocal masses, with favorable oncologic and cosmetic outcomes. The QOL analysis indicates high patient satisfaction. These results support the use of oncoplastic surgery in the management of breast cancer.

RESUMO

BACKGROUND: Round nano-surface Ergonomix (Motiva, Establishment Labs; Alajuela, Costa Rica) implants were developed to address concerns regarding capsular contracture and textured anatomical breasts implants. OBJECTIVES: The authors describe their early experience with Ergonomix implants in breast reconstruction. METHODS: The authors retrospectively reviewed the charts of 212 patients (321 breasts) who underwent breast reconstruction employing round nano-surface Ergonomix implants between June 2017 and December 2020. Patients were followed for at least 12 months postoperatively. Demographics, surgical data, and postoperative surgical outcomes were recorded. Postoperative physical well-being and satisfaction with the breasts and implant were evaluated with Breast-Q questionnaires. RESULTS: Of 211 patients, 75.4% had surgery due to cancer, and 24.6% underwent prophylactic surgery. Major complications occurred in 21 breasts (6.5%), of which 20 underwent revision operations. Reconstruction failed in 1 case (0.3%). Eleven breasts (3.4%) had minor complications. Immediate breast reconstruction, irradiated breasts, and smokers had higher rates of complications (P = 0.009, 0.02, 0.022, respectively). Rippling was more common in the pre-pectoral implant plane compared with sub-pectoral reconstruction (9% vs 1.2%, P = 0.001). Capsular contracture rate was 0.9% and occurred only in irradiated breasts. Implant malposition (inferiorly and laterally) occurred in 6.5% of the breasts, with no association between implant malposition and implant plane. Early follow-up demonstrated high patient satisfaction with the implant and breasts, and high scores in terms of patients' physical well-being. CONCLUSIONS: Breast reconstruction employing the round nano-surface Ergonomix implant yielded low complication rates and high patient satisfaction. The transition from macro-textured to nano-surface implants has operative implications requiring a learning curve and surgical adjustments.

RESUMO

ABSTRACT: We present a case report of a 48-year-old woman with a late-onset seroma of her left breast, 6 years after removal of her textured breast implants. At that time, she also had a late-onset seroma of her left breast, and capsulectomy was performed along with removal of the implants. The current late seroma presentation, which followed 6 years of uneventful healing, was treated with en bloc excision of the encapsulated seroma. Pathology results were concordant with locally invasive anaplastic large cell lymphoma (ALCL). Review of her previous seroma cytology from 6 years ago was performed given the current updated guideline standards on breast implant-associated ALCL (BIA-ALCL). Evidence of BIA-ALCL confirmed the patient had the diagnosis 6 years ago. The disease persisted and remained indolent for 6 years and manifested clinically as a late seroma of the left breast. This case report emphasizes the high degree of suspicion that is required in late seroma cases involving textured breast implants or a history of textured breast implants, along with the need for en bloc capsulectomy as a primary treatment for diagnosed BIA-ALCL to avoid incomplete capsulectomy and recurrence of the disease.

RESUMO

INTRODUCTION: Lymphedema is a pathological condition in which intercellular protein-rich fluid accumulates and leads over time to inflammation, adipose tissue hypertrophy and fibrosis. Secondary lymphedema is caused by injury or blockage of the lymphatic system and the main cause in the Western world is the treatment of a variety of cancers, the main one being breast cancer. Chronic arm edema after breast cancer surgery is a common problem with an estimated incidence of 1 in 5 patients after breast cancer treatment. In this article we review the main risk factors, approaches to reducing the risk of developing lymphedema after treatment for breast cancer and existing treatment protocols for lymphedema including the surgical innovations in this field and our experience in these innovative surgical approaches. To date, 26 physiological surgeries have been performed at the Tel Aviv Medical Center using the microsurgical approach for treating lymphedema. These surgeries had no significant complications and the improvement was observed to be greater in the group of patients with secondary lymphedema. Lymphovenous anastomosis and vascularized lymph node transfer offer promising solutions for the treatment of breast cancer related lymphedema. The introduction of additional techniques and the refinement of these procedures will probably continue to improve the results in the future.

RESUMO

BACKGROUND: Reduction mammoplasty in patients with gigantic breast hypertrophy runs a high risk of complication. Traditionally, inferior pedicle reductions or free nipple grafting techniques have been recommended for gigantic breasts on the basis of measurements and expected resection weights. The superiomedial pedicle (SMP) technique has been less commonly used, due to concerns of vascular inadequacy. This study examines the outcomes of SMP in large reductions and outlines suggested modifications for enhanced safety. METHODS: This is a retrospective review of all patients who underwent SMP breast reduction in our institution between 2005 and 2016. Included are cases with resection weights greater than 800 g. RESULTS: A total of 173 patients with 341 breasts were included. Mean sternal notch to nipple (SNN) distance was mean 35.0 ± 6.6 cm (range 23-44.5) on the left and 34.9 ± 6.6 cm (range 18-46) on the right. Mean resection weight was 1152.2 ± 368.6 g (range 810-2926) on the left and 1159.4 ± 326.6 g (range 800-2528) on the right. The total complication rate was 22.7%. Minor complications occurred in 63 (18.6%) breasts. Major complications occurred in 12 (4.1%) breasts. NAC congestion and partial necrosis occurred in 1.8% and total NAC necrosis in 0.9%. CONCLUSION: The SMP reduction technique is a safe option for gigantic breast reduction with comparable complication rates to other techniques. Preoperative measurements or resection weights are not reliable risk factors alone. High tissue density may be a significant risk factor. High-risk breasts mandate surgical planning and should be tailored to include technical modifications as described.

RESUMO

INTRODUCTION: Paralysis of the facial mimetic muscles causes loss of voluntary and non-voluntary muscle function, as well as facial tone. This is a devastating condition with profound functional, aesthetic and psychological consequences. Etiologies include congenital paralysis and acquired paralysis following viral infection, trauma, head and neck tumors, iatrogenic damage and more. Clinical presentation includes ocular symptoms (dry eye, epiphora, corneal irritation), nasal symptoms (nasal obstruction) and oral symptoms (drooling and speech disturbances). Reconstruction of facial nerve function is based on renewing the neural input to the paralyzed face in parallel with transferring a functioning muscle. The gold standard in long term facial paralysis reanimation includes a two-stage procedure that involves cross-face nerve grafting and later on a free gracilis muscle transfer. This method allows reconstruction of a symmetric, spontaneous and voluntary smile. In cases when cross-face nerve grafting is impossible, a free-gracilis muscle transfer is performed with neural coaptation to another cranial nerve, most commonly the motor nerve to the masseter muscle (of the trigeminal nerve). Non-microsurgical methods for facial reanimation exist, however, nowadays they are rarely performed. In addition to the surgical reconstruction, other surgical and non-surgical procedures are performed for functional and aesthetic symmetrization purposes. These include fat injection to the face, botulinum toxin injection, oculoplastic procedures and more. In this article we describe our patient population with facial nerve paralysis, common facial reanimation procedures, considerations in choosing the appropriate reconstruction procedure and the general approach for treatment of facial paralysis in our multidisciplinary facial paralysis clinic.

RESUMO

PURPOSE: There are no evidence-based guidelines for surveillance of women after bilateral mastectomy and reconstruction. Several societies recommend against routine breast imaging in this setting. Despite these recommendations, magnetic resonance imaging (MRI) is frequently used to follow these women. We sought to examine the findings on MRI studies done in this setting. METHODS: This is a retrospective cohort study including all consecutive MRI exams done after bilateral mastectomy and reconstruction between January 2010 and April 2018. Data collected included demographic information, family history, BRCA status, indication for bilateral mastectomy, type of reconstruction, findings on MRI, and work-up of MRI findings. Cancer detection rate and interval cancer rates were calculated. RESULTS: One hundred fifty-nine women had 415 surveillance MRI exams. Most (372, 90%) studies were done in women with implant-based reconstruction. Four hundred and five (98%; 95% confidence interval (CI) 96-99%) of the studies were negative. One breast recurrence was found on MRI (cancer detection rate 2.4 per 1000 MRI exams, 95% CI 0.4-13); however, this woman was simultaneously diagnosed with metastatic disease. The false-positive rate was 90% (95% CI 54-99%). During follow-up three women were diagnosed with local recurrence (interval cancer rate 5 per 1000, 95% CI 1.3-17) and 4 women were diagnosed with metastatic disease. CONCLUSION: The yield of surveillance MRI in women with bilateral mastectomy and reconstruction is very low. As most of the cohort had retro-pectoral implant-based reconstruction, it appears safe to recommend against surveillance MRI in this setting regardless of the indication for mastectomy.

RESUMO

BACKGROUND: Breast implant-associated anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin's lymphoma that is found around breast implants. ALCL was discovered only two decades ago. In Israel we currently have four diagnosed cases (as of 2018). Until recently, the estimated incidence was 1:300,000 women with breast implants, while recent reports range from 1:3817 to 1:30,000. OBJECTIVES: To determine the occurrence of breast implant-ALCL in Israel. METHODS: We conducted a retrospective analysis of the four patients diagnosed with ALCL in Israel. Cytology was confirmed and the clinical data was collected. Based on the estimated number of women with breast implants in Israel, a calculation of the true incidence was completed. RESULTS: The incidence in Israel is significantly higher than the older incidence reports indicate. We estimated that the lifetime prevalence of the disease is 4:60,000 women with a textured breast implant, or 1:15,000 women with a textured breast implant in Israel. CONCLUSIONS: ALCL is not common. We support the claim that the prevalence is significantly higher than what was initially described. This finding has clinical and medicolegal implications that should be addressed accordingly.

RESUMO

BACKGROUND: There are several methods for primary breast reconstruction following oncologic resection, including alloplastic and autologous-based reconstruction. Major complications that can lead to re-operation and reconstruction failure occur in up to 25% of the patients and necessitate salvage procedures. OBJECTIVES: To present the authors' experience using a pedicled latissimus dorsi (LD) flap for the salvage of complicated and impending failed breast reconstruction. METHODS: A retrospective cohort study was conducted of all patients who underwent breast reconstruction salvage by means of an LD flap in our institution during a 5-year period. Demographic, oncologic, surgical, and postoperative data were collected and analyzed. RESULTS: Seventeen patients underwent breast reconstruction salvage with the LD flap. Fourteen patients had alloplastic reconstruction and three patients had autologous reconstruction. Postoperative complications included wound infection in three patients, minor wound dehiscence in two, and donor site seroma in two. One case of postoperative infection required re-operation with exchange of the implant with a tissue expander. All breast reconstructions were salvaged using the LD flap. Only one patient complained of functional limitations in using the arm of the harvested LD. CONCLUSIONS: The LD flap is a valuable and reliable flap for alloplastic or autologous breast reconstruction salvage and has a high rate of salvage success despite the challenging surgical environment. This flap offers a good cosmetic reconstruction outcome with relatively low donor-site morbidity and high patient satisfaction.

RESUMO

BACKGROUND: Breast conservation therapy (BCT) can cause breast distortion and asymmetry. Repair of this asymmetry by means of breast reduction or mastopexy procedures can be challenging and harbor considerably high rates of complications. METHODS: In this retrospective study, we describe our experience in repairing post-BCT breast asymmetry by performing breast reduction or mastopexy. The surgical protocol we followed consisted of stringent patient selection, thorough surgical planning, basic surgical refinements, and patient education for enhancing the likelihood of achieving a good outcome with minimal surgical complications. RESULTS: Our search of the departmental database identified 25 patients with breast asymmetry who had undergone breast reduction or mastopexy between 2009 and 2017. Corrective surgery was performed 4 years on average after the completion of radiotherapy, and those patients included eleven who had undergone breast reduction and fourteen who had undergone mastopexy on the radiated side. Two patients (8%) had major complications that required further surgery (major fat necrosis, wound infection, and breast deformation), and five patients (20%) had minor complications (infection, minor fat necrosis, wound dehiscence, and nipple congestion). All complications developed on the radiated breast. There was no correlation between the occurrence of complications and patients' demographics, tumor type, tumor location, and breast tissue resection (p > 0.05). CONCLUSION: Only two of our 25 patients had major complications following breast reduction and mastopexy for the repair of asymmetry post-BCT. Following our four-step protocol was instrumental in leading to the successful performance of these procedures.

RESUMO

BACKGROUND: The superomedial vertical scar breast reduction (SVBR) described by Hall-Findlay is gaining popularity among surgeons worldwide. The aim of this study was to evaluate its long-term aesthetic outcome, the extent of quality of life improvement and the factors that influence patient satisfaction and reviewers' evaluation of aesthetic/surgical outcome. METHODS: In this historical prospective study, we included women who underwent SVBR at least one year prior to enrollment and responded to a quality of life questionnaire. Their breasts were photographed, measured and evaluated by the plastic surgery staff. RESULTS: A total of 40 patients responded to the questionnaire, and the breasts of 31 of them were measured and photographed. All 31 patients had good breast symmetry according to objective breast measurements. There was a clear correlation between the patients' and the reviewers' scores of breast symmetry, scar appearance and breast shape (r = 0.4-0.65, r = 0.432-0.495 and r = 0.335-0.403, respectively). The factor that most influenced reviewers' and patients' satisfaction with the overall aesthetic outcome was the breast-to-body proportion. CONCLUSIONS: The proportions between the breast size and the patient's body habitus are pivotal to patient satisfaction and should be taken into consideration when planning a reduction mammaplasty. The SVBR technique for breast reduction provided good cosmetic outcome and symmetry over a long-term follow-up.

RESUMO

BACKGROUND: Postmastectomy radiation therapy (PMRT) is a widely accepted treatment for locally advanced breast cancer. Some patients require additional boost radiation to the internal mammary nodes as the part of regional nodal irradiation (RNI). Delayed breast reconstruction with an autologous free flap using the internal mammary vessels for microvascular flap anastomosis is a common practice for these patients. The aim of our study was to evaluate the effect of RNI on autologous microvascular breast reconstruction. PATIENTS AND METHODS: A retrospective study was performed on 57 patients (69 flaps) undergoing deep inferior epigastric perforator (DIEP) flap for delayed breast reconstruction after radiation therapy. The study group included 37 patients (65%) who received PMRT and RNI to the internal mammary nodes. The control group included 20 patients (35%) who received PMRT alone. Early and delayed surgical complications, including wound complications, fat necrosis, and flap loss, were compared between the groups. RESULTS: The patient demographics in both groups were similar. Complication rate showed a higher trend in the study group for flap loss (8.3% versus 0%) and vascular anastomosis failure (5.6% versus 0%), but with no statistical difference (p = 0.54, 0.53, respectively). The control group showed a higher trend in fat necrosis (25% versus 8.3%, p = 0.11). CONCLUSIONS: DIEP flap breast reconstructions with internal mammary vessels anastomosis should be performed with cautious in patients who had received RNI to internal mammary nodes because of potential added risk for surgical complications.

RESUMO

BACKGROUND: Infection and capsular contracture are two of the most significant complications of breast-implant surgery. Both complications are associated with bacterial contamination of the implant surface. Plasma activation of the surface of a silicone breast implant changes its surface properties from water repelling (hydrophobic) to water absorbing (hydrophilic), thus making it possible for antibacterial irrigants to temporarily adsorb onto the implant surface. OBJECTIVES: To support our hypothesis that by changing the surface properties we could render antibacterial irrigation more effective in inhibiting bacterial growth on a breast implant shell. METHODS: An in vitro study using silicone discs cut from a textured silicone breast implant shell was performed by treating some of the discs with plasma activation and then exposing the discs to contamination with either Staphylococcus aureus or Pseudomonas aeruginosa and then variously treating the discs with 10% povidone iodine, Cefazolin, or Gentamicin. Bacterial contamination was verified and counted using contact plates as well as culture media. RESULTS: Plasma activation changed the wetting properties of the disc's surface from hydrophobic to hydrophilic. Nonplasma activated contaminated discs demonstrated clear bacterial growth both in the untreated group and in the antibacterial-treated group. Combining antibacterial treatment with plasma activation resulted in complete inhibition of bacterial growth in each of the groups treated with antibacterial irrigants. CONCLUSIONS: Combining plasma activation with topical antibacterial irrigants can inhibit the growth of bacteria on implant shell discs. By changing the properties of the surface from hydrophobic to hydrophilic, the adsorption of the antibacterial irrigants is enhanced.

RESUMO

BACKGROUND: Immediate breast reconstruction in large and ptotic breasts is challenging, often requiring skin-reducing procedures. The Wise-pattern skin-reducing mastectomy (WPSRM) technique provides reliable one-stage implant coverage using the pectoralis muscle and a de-epithelialized inferiorly based dermal flap. However, de-vascularization may result in mastectomy skin flap necrosis. We aimed to critically evaluate and isolate patients at high risk of complications using this procedure. METHODS: We retrospectively reviewed consecutive patients undergoing WPSRM by the senior author from January 2008 to December 2011. Data collected included patient demographics, breast cancer staging, smoking, preoperative radiation, chemotherapy, BMI, mastectomy weight, implant size and type. We analyzed their effect on complications, revisions and failure rate. RESULTS: Fifty-nine WPSRMs were performed in 39 patients with a minimum of 12-month follow-up. Complications occurred in 43.75% patients and 34.88% breasts. Multivariate statistical analysis revealed that age (p = 0.093) and BMI (p = 0.631) were not significant risk factors as opposed to previously published data. Mastectomy weight was significantly associated with major complications requiring secondary surgery (odds ratio per 100 g of breast tissue was 1.18; 95% CI 1.01-1.39; p = 0.036) as 90.5% of our complications occurred in those patients with mastectomy weight exceeding 700 g. Complications were reduced twofold when selecting a Becker adjustable implant over a silicone one for these higher mastectomy weights. CONCLUSION: WPSRM was found to be associated with an increased complication rate in patients with high mastectomy weights and immediate reconstruction with silicone implants. We propose an algorithm offering better patient selection for this technique in immediate breast reconstruction.

RESUMO

OBJECTIVES: Dalbavancin, a semi-synthetic lipoglycopeptide, is characterized by a long plasma half-life, which allows weekly dosing. Dalbavancin may be a good treatment option for patients with deep sternal wound infections owing to its improved pharmacokinetic profile and antibacterial activity compared with currently used antibiotics. Here we evaluated the efficacy of 7 or 14 days of treatment with dalbavancin, compared with vancomycin and with saline, in reducing sternal bone MRSA counts in a rat Staphylococcus aureus deep sternal wound infection model. METHODS: A mid-sternal wound was surgically induced in anaesthetized rats. A clinical strain of MRSA was injected into the sternum to establish infection. Rats were treated intraperitoneally for 7 or 14 days with dalbavancin, vancomycin or saline. The number of cfu per gram of sternum or spleen tissue was determined using viable counts. The antibacterial efficacy was determined by the reduction in bacterial counts per gram of sternum or spleen tissue in each treatment group. RESULTS: Treatment with dalbavancin was superior to treatment with saline for 7 days (0.75 log reduction in bone cfu) or 14 days (>3 log reduction in bone cfu) and similar to treatment with vancomycin. Additionally, dalbavancin was also effective in reducing systemic dissemination of MRSA. CONCLUSIONS: Dalbavancin is effective in the treatment of MRSA rat sternal osteomyelitis.

RESUMO

PURPOSE: The fibula flap serves as the workhorse for many mandibular defect types. For massive defects that include the mandible, floor of the mouth, and tongue, reconstruction might mandate a 2-flap approach. This report describes a systematic yet flexible design of a single composite osseocutaneous fibula flap for such cases. PATIENTS AND METHODS: From 2003 through 2011, 5 patients underwent surgery for T4 squamous cell carcinoma and adenoid cystic carcinoma. They underwent wide resection of the mandible and floor of the mouth with hemi- to subtotal glossectomy. A large skin paddle was designed on the leg using a customized template consisting of 3 components matching the alveolar, floor-of-mouth, and tongue segments. The round tongue component was folded using its thickness to provide 3-dimensional volume and form in place of the missing tongue. The other 2 components had a crescent shape and were adjusted intraoperatively to match the resected defect. RESULTS: All 5 flaps survived, with 1 case of flap loss that was successfully replaced. Delayed healing of the leg donor site was encountered in 4 patients. CONCLUSION: The proposed single 3-dimensionally folded flap design provides ample tissue to replace bony and soft tissue elements for major anterior or lateral segment defects. There was morbidity owing to donor-site complications but these were treatable, with recorded functional restoration.

RESUMO

Distal tibial tumor ablation results in combined soft tissue and bone defect that involves the ankle joint. This area is unique and problematic because it combines low caliber limb size, relatively soft tissue deficiency, suboptimal bone and soft tissue healing ability, and the need to sustain increased mechanical loads. The management is difficult, controversial, and traditionally was treated by primary amputation. We present our experience with a limb sparing surgery using biological reconstruction.Between 2004 and 2007, 5 patients with malignant bone tumors of the distal tibia underwent tumor resection and reconstruction with free vascularized osteoseptocutaneous fibula flap. The average age was 33.2 years (range, 11-62 years). In all cases, a skin island was harvested and used for wound closure. Arthrodesis of the ankle joint was preformed in all patients. Double fixation system was used to provide stability and avoid flap rotation.All flaps survived. There were no major complications. One patient had partial loss of the skin paddle that was treated conservatively. Callous formation was documented after an average time of 4 months, partial weight bearing after an average time of 4 months, and full weight bearing after an average time of 11.5 months. All patients regained almost normal ambulation within a year.

RESUMO

BACKGROUND: Oncoplastic breast reduction in women with medium to large breasts has reportedly benefitted them both oncologically and cosmetically. We present our experience with an oncoplastic breast reduction technique using a vertical scar superior-medial pedicle pattern for immediate partial breast reconstruction. METHODS: All patients with breast tumours who underwent vertical scar superior-medial pedicle reduction pattern oncoplastic surgery at our centre between September 2006 and June 2010 were retrospectively studied. Follow-up continued from 12 months to 6 years. RESULTS: Twenty women (age 28-72 yr) were enrolled: 16 with invasive carcinoma and 4 with benign tumours. They all had tumour-free surgical margins, and no further oncological operations were required. The patients expressed a high degree of satisfaction from the surgical outcome in terms of improved quality of life and a good cosmetic result. CONCLUSION: The vertical scar superior-medial pedicle reduction pattern is a versatile oncoplastic technique that allows breast tissue rearrangement for various tumour locations. It is oncologically beneficial and is associated with high patient satisfaction.


CONTEXTE: Chez des femmes qui avaient une poitrine de moyenne à volumineuse, la réduction mammaire oncoplastique aurait exercé des bienfaits, tant au plan oncologique que cosmétique. Nous présentons notre expérience d'une technique de réduction mammaire oncoplastique à cicatrice verticale et pédicule supéromédian pour une reconstruction mammaire partielle immédiate. MÉTHODES: Tous les cas de tumeurs mammaires soumis à la réduction à cicatrice verticale et pédicule supéromédian en chirurgie oncoplastique dans notre centre entre septembre 2006 et juin 2010 ont été passés en revue rétrospectivement. Le suivi s'est échelonné sur 1 à 6 ans. RÉSULTATS: Vingt femmes (âgées de 28 à 72 ans) ont été inscrites : 16 étaient atteintes d'un cancer envahissant et 4 de tumeurs bénignes. Elles présentaient toutes des marges chirurgicales libres de tumeur et aucune autre intervention oncologique n'a été nécessaire. Les patientes ont exprimé un degré élevé de satisfaction à l'endroit des résultats de la chirurgie pour ce qui est de l'amélioration de leur qualité de vie et de l'effet cosmétique positif. CONCLUSION: La technique de réduction à cicatrice verticale et pédicule supéromédian est une technique oncoplastique flexible qui permet un réarrangement des tissus mammaires en fonction de la localisation des tumeurs. Au plan oncologique, elle est bénéfique et associée à un degré élevé de satisfaction chez les patientes.
