Background: Although reduction mammaplasty is a well-described technique for aesthetic purposes, there are few previous reports regarding its application and clinical outcome following conservative breast surgery reconstruction. The purpose of this study was to analyze the feasibility of the technique and its outcome following conservative breast surgery. Methods: Oncologic data and information on age, body mass index, smoking history, and comorbid conditions were collected. Reconstructed and opposite breast complications were evaluated. Reduction mammaplasty was indicated to reconstruct moderate breast defects in patients with enough remaining breast tissue. Mean follow-up was 22 months. Results: Seventy-four patients underwent immediate reduction mammaplasty following breast-conserving surgery. In 55.4 percent of patients, tumors measured 2 cm or less (T1) and in 47.2 percent they were located in the upper outer quadrants. Breast complications occurred in 13 patients (17.6 percent), with skin necrosis in six (8.1 percent), infection in two (2.7 percent), partial areola necrosis in two (2.7 percent), dehiscence in two, and total areola necrosis in one (1.35 percent). Late complications represented by skin lesions and fat necrosis were observed in five patients (6.8 percent). Obese patients and smokers had a significantly higher rate of reconstructed breast complications compared with the normal/overweight patients (p = 0.002) and nonsmokers (p = 0.043). No significant association between complications and age, hypertension, diabetes, axillary lymph node dissection, or chemotherapy was found. Conclusions: Reduction mammaplasty is a consistent technique for reconstruction following breast-conserving surgery. Complications are more often observed in the reconstructed breast, and obese patients and smokers are higher risk patients.

Background: The latissimus dorsi myocutaneous flap is frequently used for total breast reconstruction; however, few reports have been available regarding clinical outcome following conservative breast surgery. The aim of this study was to perform a retrospective review on 48 patients undergoing immediate latissimus dorsi myocutaneous flap surgery following conservative breast surgery between 1999 and 2004. Methods: Information on age, body mass index, smoking history, comorbid medical conditions, and oncologic status was collected. Reconstructed breast and donor-site complications were evaluated. Results: Mean follow-up was 16 months. In 56.2 percent of patients, tumors measured 2 cm or less (T1) and in 47.9 percent were located in the upper outer quadrants. Flap complications occurred in seven and donor-site complications occurred in 12 of 48 patients. Dorsal seroma (20.8 percent), dorsal dehiscence (6.2 percent), and partial flap loss (6.2 percent) were the most common complications. Surgical intervention with skin suture was necessary in two cases of dorsal wound dehiscence. Partial flap losses were limited and were treated by a conservative approach. A significant as-sociation (p =0.035) was detected between dorsal seroma and obesity (body mass index ≥ 30 kg/m2) and was associated with a 5.2-fold increase in the odds of developing this complication. No significant association between complications and age, smoking history, hypertension, diabetes, axillary lymph node dissection, or chemotherapy was found. Conclusions: On the basis of our observations, the latissimus dorsi myocutaneous flap is a consistent technique for reconstruction following conservative breast surgery. Donor-site complications are more often observed in those who are obese; they are higher risk patients.

Background: Although the lateral thoracodorsal fasciocutaneous flap is a well-studied procedure for late breast reconstruction following radical surgery, there are few previous reports regarding its indication, flap design, and clinical outcome following conservative breast surgery. Methods: Thirty-four patients underwent immediate unilateral lateral thoracodorsal fasciocutaneous flap breast reconstructions. Mean time of follow-up was 23 months. The lateral thoracodorsal fasciocutaneous flap was indicated to reconstruct moderate lateral breast defects where there was not enough breast tissue to perform the reconstruction. Flap and donor-site complications were evaluated. Information on aesthetic results and patient satisfaction was collected. Results: All tumors were located in lateral breast regions, and 64.7 percent measured 2 cm or less (T1). Flap complications occurred in four patients (11.8 percent), with partial flap necrosis in three (8.8 percent). Donor-site complications occurred in eight (23.5 percent), with seroma in five (14.7 percent) and wound dehiscence in three (8.8 percent). The cosmetic result was considered to be good or very good in 88.2 percent, and the majority of patients were either very satisfied or satisfied. Surgical intervention was necessary in two cases of wound dehiscence. Serial dorsal puncture in cases of seroma were performed with satisfactory results. Conclusions: The lateral thoracodorsal fasciocutaneous flap is a simple and reliable technique for conservative breast surgery reconstruction. Success depends on patient selection, coordinated planning with the oncologic surgeon, and careful intraoperative management.

Background: Although use of the latissimus dorsi myocutaneous flap associated with the Biodimensional anatomical expander implant system (McGhan 150) is a reliable technique, little information has been available regarding clinical outcome following periareolar skin-sparing mastectomy reconstruction. The purpose of this study was to analyze the feasibility of the technique, surgical planning, and its outcome following skin-sparing mastectomy. Methods: Thirty-two patients underwent immediate unilateral latissimus dorsi myocutaneous flap/Biodimensional anatomical expander implant system breast reconstruction. Mean follow-up was 18 months. The technique was indicated in patients with small- or moderate-volume breasts with or without ptosis, in whom the use of abdominal flaps was precluded. Flap and donor-site complications were evaluated. Information on anesthetic results and patient satisfaction was collected. Results: Seventy-two percent had tumors measuring 2 cm or less (T1) and 78 percent were stage 0 and I according to American Joint Committee on Cancer criteria. Breast skin complications occurred in 9.4 percent. Two patients presented small breast skin necrosis, and in one patient, a wound dehiscence was observed. Donor-site complications, all represented by seroma, occurred in 12.5 percent. The cosmetic result was considered good or very good in 84.4 percent, and the majority of patients were either very satisfied or satisfied. No local recurrences were observed. All complications except two were treated by conservative means. Conclusions: The latissimus dorsi myocutaneous flap/Biodimensional anatomical expander implant system is a simple and reliable technique for periareolar skin-sparing mastectomy reconstruction. Success depends on patient selection, coordinated planning with the oncologic surgeon, and careful intraoperative and postoperative management.

BackgroundAlthough transaxillary breast augmentation (TBA) is a well-studied procedure, few previous reports exist concerning the subfascial technique, especially without endoscopic assistance. This study aimed to analyze the feasibility of the technique after breast augmentation in terms of its indication, surgical technique, limitations, and clinical outcome.MethodsFor this study, 42 patients underwent TBA without endoscopic assistance. The technique was indicated for patients with breasts of small or moderate volume without ptosis, patients who wanted no breast scars, and patients who had a poorly defined inframammary fold. The mean follow-up period was 16 months. Implant and incision approach complications were evaluated. Information on patient satisfaction was collected.ResultsA total of 14 complications occurred in 42 patients, all of them minor. Axillary incision–related complications occurred in 26% of the patients, as represented by a late axillary subcutaneous band (119%), sensory loss in the inner aspect of the arm (71%), and a hypertrophic scar and small wound dehiscence (71%). No patient presented with capsular contracture, visible rippling, or infection. Most of the patients (93%) were either very satisfied or satisfied with their result, and none regretted the surgery.ConclusionThe TBA procedure without endoscopic assistance is a simple and reliable technique for breast augmentation. Most of the complications in this study were minor and predictable. They did not interfere with the aesthetic outcome nor the normal postoperative recovery. With TBA, success depends on patient selection as well as careful intra- and postoperative management.

Alexandre Mendonça Munhoz; Eduardo Montag; Eduardo Arruda; Claudia Aldrighi; Rolf Gemperli; José Mendes Aldrighi; Marcus Castro Ferreira

Background:Reduction mammaplasty procedures and especially the superior-medial dermoglandular pedicle (SMDP) technique are frequently used for esthetic objectives; however, few reports have been available regarding its application following conservative breast surgery reconstruction. The purpose of this study is to analyze the feasibility of the technique and describe the surgical planning and its outcome following oncologic surgery. Methods:Thirty-nine patients underwent immediate bilateral SMDP breast reconstructions. Mean time of follow-up was 20 months. SMDP was indicated to reconstruct inferior breast defects in patients with enough remaining breast tissue. Reconstructed (RB) and opposite (OB) breast complications were evaluated and information on esthetic result and patient satisfaction was collected. Results:Tumors (51.2%) measured 2 cm or less (T1) and 66.6% were located in the lower outer quadrants. Mean change in nipple position was 12.5 cm. Immediate RB complications occurred in 8 patients (20.5%), with skin necrosis in 3 (7.6%), infection in 2 (5.1%), dehiscence in 2 (5.1%), and partial areola necrosis in 1 (2.5%) patient. Late complications were observed in 7.6%. All late complications were observed after adjuvant radiotherapy. The cosmetic result was considered to be good or very good in 84.6%, and the majority of patients were either very satisfied or satisfied. All complications were treated by conservative approach. Conclusion:SMDP is a reliable technique and should be given primary consideration in cases of lower quadrant reconstruction. The success of the procedure depends on patient selection, coordinated planning, and careful intraoperative management.

Background: Transaxillary breast augmentation has gained popularity because of the good aesthetic results and scar placement in a less visible position. As breast-augmented patients age, an increasing number of breast cancer cases can be expected. Sentinel lymph node detection (SLND) is a well-established technique in breast cancer. To date, no information is available regarding the feasibility of SLND for patients with previous transaxillary implants.Methods:A 28-year-old women with bilateral breast hypoplasia underwent a bilateral breast augmentation by the transaxillary approach. One week earlier, SLND was accomplished through two periareolar injections of 0.1 mCi 99m-technetium-labeled fitate and lymphoscintigraphy. A 3.5-cm-long axillary incision was performed, and the dissection continued through the subfascial plane to create the implant’s pocket. A silicone gel implant (215 g round, low-profile, textured Silimed) was inserted.Results: A satisfactory aesthetic result was obtained. Two postoperative lymphoscintigraphies were performed (15 days and 7 months after surgery) with satisfactory SLND. No complication was noted.Conclusion: The initial data show that SLND in the setting of prior breast implant augmentation through the transaxillary approach is feasible. Additional prospective studies and larger clinical series are necessary to analyze the accuracy of SLND for patients with previous breast implants.

Background:Bilateral mammaplasty or mastopexy is frequently used for oncoplastic objectives. However, little information has been available regarding outcome following immediate and delayed reconstruction. Method:Patients were divided into Group I (immediate reconstruction) and Group II (delayed reconstruction). Retrospective review was performed to compare complications, length of hospital stay, revision surgeries, and satisfaction. The associations between the complications with potential risk factors (timing, age, body mass index, smoking, and comorbid medical conditions) were analyzed. Results:There were a total of 144 patients with a mean follow-up of 47 months. Of the 106 patients in Group I, complications occurred in 24 (22.6%), skin necrosis was observed in 7.5%, fat necrosis in 5.6%, and 6.6% patients developed local recurrence. Mean period of hospitalization was 1.89 days. Of the 38 patients of the Group II, complications occurred in 12 (31.5%), skin necrosis was observed in 7 (18.4%), fat necrosis in 4 (10.5%), and 5.2% patients developed local recurrence. Mean period of hospitalization was 1.35 days. Increased length of hospital stay greater than 1 day (P < 0.001) and the number of revision surgeries (P = 0.043) were associated with the timing of the reconstruction. In univariate analysis, no difference between groups was found with respect to complication incidence (P = 0.275); however, after adjusting for other risk factors, the probability of complications tend to be higher for Group II (OR = 2.65; 95% confidence interval = 1.01–7.00; P = 0.049). Conclusions:On the basis of the results of our study, the probability of complications tends to be higher for delayed reconstructions, and it is demonstrated that obesity and smoking are risk factors for complications. Ultimately, these data may facilitate the provision of individualized risk information for shared medical decision-making.

Abstract:  Although breast reconstruction with deep inferior epigastric perforator (DIEP) flap is a well‐described technique, few publications have specifically reported the technical aspects and the outcome following skin‐sparing mastectomy (SSM). The aim of this study is to analyse the feasibility of its immediate application and to describe the operative planning, outcome and complications after SSM. 27 patients underwent 30 DIEP flap breast reconstructions with all immediate and 3 bilateral. Mean time of follow‐up was 29 months. Breast skin, DIEP Flap and donor‐site complications were evaluated. Information on patient satisfaction was collected. 70% had tumors measuring 2 cm or less (T1) and 74% were stage 0 and I according to American Joint Committee on Cancer. Breast skin complications occurred in 7.4%, all represented by small areas of skin necrosis. Partial losses were observed in two (7.4%) patients (less than 15% of total area) and total DIEP loss in 1 (3.7%). Donor‐site complications represented by bulging occurred in only one patient (3.7%). The majority of patients were either very satisfied or satisfied. One local recurrence was observed. All complications except 2 were treated by a conservative approach. The DIEP flap is a reliable technique for SSM reconstruction. Success depends on patient selection, coordinated planning with the oncologic surgeon and careful intraoperative and postoperative management. The main advantage is that patients can safely undergo dual procedures with the added aesthetic benefits in breast and abdominal donor site.

Background:The transaxillary approach plays a useful role for breast augmentation due to scar placement in a less visible position. However, the future impact of the procedure on the lymphatic drainage patterns and sentinel lymph node (SLN) detection remains controversial. To date, no information is available regarding the feasibility of SLN identification in patients with previous transaxillary breast augmentation (TBA). Methods:Twenty-six patients underwent primary TBA. Mean follow-up was 8.3 months. All patients were submitted to lymphoscintigraphy (LSG), with a dose of 0.1 mCi 99m-technetium-labeled dextran 1 week before (preop-LSG) and 10 days (Po10 days-LSG) after TBA. Results:Preop-LSG was successful in all patients. Mean number of SLN detected was 2 per patient (range, 1 to 4) in the right axilla and 2.2 (range, 1 to 5) in the left. In Po10 days-LSG, SLN detection was successful in 92.3%. Mean number of SLN detected was 2.3 per patient (range, 0 to 7) in the right axilla and 1.8 (range, 0 to 6) on the left. Two patients (7.6%) failed to reveal the accumulation of radioactivity in Po10 days-LSG. Comparing bilaterally, in the number of SLN detected (P = 0.838) and the SLN uptake (P = 0.067) between Preop-LSG and Po10 days-LSG, no significant differences were observed. No major complication was noted. Conclusion:The initial data illustrate that SLN detection in the setting of prior TBA is feasible in a great part of patients. Additional long-term studies are necessary to investigate the accuracy of SLN biopsy in subgroups of breast cancer patients with previous breast implants.
