Abstract
BACKGROUND Several alternative flaps have been introduced and used for autologous breast reconstruction. However, as body fat distribution is different among patients, the donor of choice for sufficient breast projection varies between patients. METHODS Patients who underwent autologous breast reconstruction from Jan 2018 to Sep 2022 were included. Age, body mass index (BMI), smoking history and hypertension, and diabetes occurrence were collected as baseline demographic data. Breast projection with five types of flap thickness was measured based on computed tomography angiography. Analysis was performed for five major autologous flaps for breast reconstruction. RESULTS A total of 563 patients were included in the study. The mean age of the patients was 47.4 ± 7.9 (standard deviation; SD) years. The mean BMI of the patients was 24.0 ± 3.4 kg/m2. Only the correlation between flap thickness to breast projection ratio and age in the PAP flap illustrated statistical significance (p = .039), but the correlation coefficient was quite low (r = -0.087). Slim patients who had lower BMIs (under 25 kg/m2) had significantly higher sufficient flap thickness for breast reconstruction than patients with higher BMIs over 25 kg/m2 in the profunda artery perforator (PAP) flap (p < .001), the lumbar artery perforator (LAP) flap (p < .001), and the superior gluteal artery perforator (SGAP) flap (p < .001). CONCLUSIONS The deep inferior epigastric perforator flap provided sufficient thickness and was not usually affected by age and BMI. The PAP, LAP, and SGAP flaps tended to maintain the thickness of the flap even when BMI decreased, so they are advantageous for reconstruction in slim patients. This study contributes evidence in consideration of flap selection in autologous breast reconstruction.

Abstract
SUMMARY Recent reports have introduced robotic breast surgery for immediate breast reconstruction with an implant. However, relevant reports of robot-assisted breast reconstruction including capsulectomy are limited. Although capsulectomy lowers risk of capsular contracture and thus contributes to better aesthetic outcomes, total capsulectomy may have complications, such as injury to axillary structures or chest wall and overlying skin devascularization. To minimize the risk of injury, the authors used a robotic system with Da Vinci SP, which has freely movable arms and clear, magnified three-dimensional vision, for total capsulectomy. Compared with conventional procedures, robotic surgery has the critical advantage of minimal incision and concealed scars, contributing to positive aesthetic outcomes. This study suggests that robot-assisted capsulectomy is technically feasible and safe for patients undergoing breast reconstruction with immediate reimplantation.

Abstract
BACKGROUND Although there are many acellular dermal matrix (ADM) products, the sterilization process varies for each product. We compared the clinical outcomes of immediate prepectoral direct-to-implant (DTI) breast reconstruction with and without sterilization products. METHODS This was a retrospective study of immediate prepectoral DTI breast reconstructions performed between 2018 and 2020. We classified patients depending on whether the used ADM products had undergone radiation sterilization and compared the patient demographics and surgical outcomes, including seroma, infection, mastectomy flap necrosis, capsular contracture, and implant failure. RESULTS The study included 357 patients, 182 in the no-sterilization group and 179 in the sterilization group. The ADM size differed significantly between the no-sterilization and sterilization groups (122.7 cm2 vs. 145.4 cm2, respectively, P = 0.01). There were no significant differences in overall rates of complications between the two groups, including seroma (P = 0.28), infection (P = 0.63), mastectomy flap necrosis (P = 0.76), and capsular contracture (P = 0.76). However, implant failure from infection (0% vs. 3.4%, P = 0.01) and drainage amount (690.3 mL vs. 779.36 mL, P = 0.04) with similar removal days were significantly higher in the sterilization group. CONCLUSION The authors demonstrated similar complication rates for seroma, infection, mastectomy flap necrosis, and capsular contracture. Whereas a bigger size of ADM was needed to cover a similar implant volume, and drain amount was higher in the sterilization group, the salvage rate from infection was higher in the no-sterilization group with a significant difference.

Abstract
SUMMARY Laser imaging detection and ranging (LiDAR) is a modern three-dimensional (3D) technology that uses a time-of-flight method based on the round-trip time of an infrared laser beam to detect the presence and features of objects. The iPhone 12 Pro is the first smart mobile device with built-in LiDAR sensors. The authors' team developed a software application based on iOS devices with built-in LiDAR sensors for 3D breast scanning and automatically analyzing the breast's geometric measurement. Breast geometry, including midclavicle-to-nipple distance, sternal notch-to-nipple distance, nipple-to-inframammary fold (IMF) distance, distance between nipples, and body circumference on nipple and IMF level were measured using the software application and tapeline. The relative technical error of measurement (rTEM) value was used to calculate the error ratios between the measurements acquired by the software application and those of the tapeline. Good rTEM values ranging from 2.99% to 5.19% were found in the midclavicle-to-nipple distance, sternal notch-to-nipple distance, distance between nipples, nipple-level circumference, and IMF-level circumference. However, there was a poor rTEM value greater than 10% in the nipple-to-IMF distance. The proposed software application using current iOS devices with built-in LiDAR sensors can provide an ideal 3D scanning system that has a low cost burden, good accuracy, portability, and ease of use.

Abstract
BACKGROUND Direct-to-implant breast reconstruction is a standard method of implant-based reconstruction; however, the risk of skin necrosis and implant failure exists. During simultaneous contralateral augmentation, an implant larger than the resected tissue must be inserted to balance both sides, which may increase the risk of complications. This study examined the differences in the incidence of complications between the single-stage direct-to-implant reconstruction and 2-stage reconstruction when contralateral augmentation was performed simultaneously. METHODS This study included 99 patients who underwent implant-based breast reconstruction with contralateral augmentation between 2012 and 2020. A retrospective chart review was conducted and the patients were divided into 2 groups: the single-stage reconstruction (n = 61) and 2-stage reconstruction (TSR, n = 38) groups. Demographic data and surgical and oncological information were collected. Complications including skin necrosis and reconstruction failure were investigated as the primary outcome. RESULTS Implant volume and contralateral implant volume were significantly greater in TSR group than in the single-stage reconstruction group. There were no significant differences in the incidence of complications and reconstruction failure rates between both groups. The nipple-sparing mastectomy was the risk factor for complications. Furthermore, the risk factors for mastectomy skin necrosis were implant volume and differences in the volume of both implants. CONCLUSIONS Single-stage reconstruction did not increase the risk of complications compared with TSR when implants that were larger than the resected tissue were inserted after mastectomy. Proper patient selection and selection of implants that are not excessively large could satisfy patients' cosmetic needs in a single operation.

Abstract
BACKGROUND This study compared conventional and robot-assisted mastectomy and breast reconstruction. To the best of our knowledge, this study is the first to report the results of robot-assisted mastectomy and breast reconstruction as well as a comparison of patient-reported outcomes. METHOD A retrospective study included 473 breasts of 423 patients who underwent conventional mastectomy and breast reconstruction and 164 breasts of 153 patients who underwent robot-assisted mastectomy and breast reconstruction from July 2019 to October 2021. Demographic and oncologic data, reconstructive outcomes, and patient-reported outcomes (BREAST-Q) were evaluated. The results of implant-based and autologous breast reconstruction were separately evaluated. RESULTS Skin necrosis requiring surgical debridement occurred significantly more frequently in the conventional group (8.0%) than in the robot-assisted group (2.0%) in implant-based reconstruction (p=0.035). At 6-12 months, robot-assisted breast reconstruction showed a higher sexual wellbeing score for implant-based reconstruction and a higher physical wellbeing score for autologous breast reconstruction than conventional breast reconstruction according to the BREAST-Q questionnaire. CONCLUSION Robot-assisted mastectomy and breast reconstruction was associated with less skin necrosis and better patient-reported outcomes (sexual wellbeing for implant-based reconstruction and physical wellbeing for autologous breast reconstruction) than the conventional option. Robotic surgery could be a good option for mastectomy and breast reconstruction.

Abstract
Background In this study, we established two rat models that mimic human submuscular and premuscular breast reconstruction. We analyzed the capsule formation according to surgical techniques and adjacent tissues, including the chest wall tissues, such as the ribs and acellular dermal matrices (ADMs) that come in contact with silicone implants. Methods This study consisted of experiments on 12 Sprague-Dawley rats that underwent implant reconstruction using ADM. They were divided into two groups: rats that underwent dual-plane implantation (n = 6; group 1) and those that underwent premuscular implant insertion (n = 6; group 2). All rats were irradiated with 35 Gy of fractionated radiation. Three months after surgery, the histology and immunochemistry of the capsule tissues of the ADM, muscle, and chest wall were analyzed. Results Overall capsule thickness was thicker in group 1. Based on the tissue in contact with the silicone implant, ADM had a thinner capsule, less inflammation, less fibrosis, and less vascularization than the muscle and chest wall tissues. Conclusions This study described two rat models of clinically relevant implant-based breast reconstruction using a submuscular and premuscular plane, ADM, and irradiation. Overall, the premuscular implantation rat model was associated with a thinner capsule. The ADM in contact with the silicone implant, even after irradiation, had superior protection from radiation compared with the other tissues.

Abstract
BACKGROUND This cadaveric study aimed to describe the anatomy of the profunda artery perforators (PAPs). METHODS In total, nine free cadavers with 18 upper thighs were dissected, 12 of which were from female cadavers, and 6 were from male cadavers. The average age of the cadavers was 84.7 ± 4.2 years. Dissection was performed to evaluate the anatomic position and characteristics of the femoral PAPs. The perforator distance from the gluteal sulcus, number of perforators, perforating muscles, diameter of the perforators, origin of the perforators, and number of nerves passing above and below the perforators were determined. RESULTS The average number of perforators that penetrate the adductor magnus muscle was 2.5. The average distance from the origin of the perforators to the gluteal sulcus was 71.72 ± 28.23 mm. The average numbers of the obturator nerves passing above and below the perforator in the adductor magnus muscle were 1.3 (range, 0-4) and 0.7 (range, 0-2), respectively. CONCLUSION The results provide a detailed anatomic basis for the PAP flap. The perforators of a PAP flap may be included in a flap with a transverse design. Sacrificing the small obturator nerves during dissection may not lead to significant donor site morbidity.

Abstract
BACKGROUND Prepectoral direct-to-implant insertion (DTI) with acellular dermal matrix (ADM) is the currently preferred operation for breast reconstruction. There are different placements of ADM, which are largely classified as wraparound placement or anterior coverage placement. Because there are limited data comparing these two placements, this study aimed to compare the outcomes of these two methods. METHODS This was a retrospective study of immediate prepectoral DTI breast reconstructions performed by a single surgeon between 2018 and 2020. Patients were classified depending on the ADM placement type used. Surgical outcomes and breast shape changes using nipple position during follow-up were compared. RESULTS A total of 159 patients were included in the study, with 87 in the wraparound group and 72 in the anterior coverage group. Demographics were similar between the two groups, excluding ADM amount used (154.1 cm 2 versus 137.8 cm 2 ; P = 0.01). There were no significant differences in the overall rate of complications between the two groups, including seroma (6.90% versus 5.56%; P = 1.0), total drainage amount (762.1 mL versus 805.9 mL; P = 0.45), and capsular contracture (4.6% versus 1.39%; P = 0.38). The wraparound group had a significantly longer distance change than that of the anterior coverage group in the sternal notch-to-nipple distance (4.44% versus 2.08%; P = 0.03) and midclavicle-to-nipple distance (4.94% versus 2.64%; P = 0.04). CONCLUSIONS Wraparound and anterior coverage placement of ADM in prepectoral DTI breast reconstruction showed similar complication rates, including seroma, drainage amount, and capsular contracture. However, wraparound placement can make the breast more ptotic in shape compared with anterior coverage placement. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
BACKGROUND This study was performed to evaluate the hypothesis that capsule formation varies according to the radiation dose in muscle tissues; chest wall tissues, including the ribs; and acellular dermal matrices (ADM) that are in contact with the silicone implant. METHODS In this study, 20 Sprague-Dawley rats underwent submuscular plane implant reconstruction using ADM. They were divided into four groups: an unradiated control group ( n = 5), nonfractionated radiation at a dose of 10 Gy ( n = 5), nonfractionated radiation at a dose of 20 Gy ( n = 5), and fractionated radiation at a dose of 35 Gy ( n = 5). Three months after surgery, hardness was measured, and histologic and immunochemical analyses of the capsule tissues of the ADM, muscle tissues, and chest wall tissues were analyzed. RESULTS As the radiation dose increased, the silicone implant became harder, but no significant difference in capsule thickness according to the radiation dose was observed. Based on the tissue in contact with the silicone implant, ADM had a thinner capsule thickness than the muscle tissues, as well as less inflammation and less neovascularization compared with the other tissues. CONCLUSIONS This study describes a new rat model of clinically relevant implant-based breast reconstruction using a submuscular plane and ADM with irradiation. The ADM in contact with the silicone implant, even after irradiation, was protected from radiation compared with the other tissues. CLINICAL RELEVANCE STATEMENT These research results could support the use of ADM in implant-based breast reconstruction for prevention of the capsular contracture, even after radiation.

Abstract
BACKGROUND This study compared the reconstructive outcomes and fat necrosis of the profunda artery perforator (PAP) flap with those of the deep inferior epigastric perforator (DIEP) flap. METHODS Data on all DIEP and PAP flap breast reconstructions performed between 2018 and 2021 at Asan Medical Center were compared. The overall reconstructive outcomes and presence of fat necrosis were analyzed through ultrasound evaluation performed by a board-certified radiologist. RESULTS The PAP (n = 43) and DIEP flaps (n = 99) were used to reconstruct 31 and 99 breasts, respectively. The average age of the patients in the PAP flap group (39.1 ± 7.3 years) was lower than in the DIEP flap group (47.4 ± 7.7 years), and the body mass index (BMI) of patients undergoing PAP flap reconstruction (22.7 ± 2.8 kg/m2) was lower than those undergoing DIEP flap reconstruction (24.3 ± 3.4 kg/m2). There was no total loss of both flaps. Donor site morbidity was higher in the PAP flap group (11.1%) compared with the DIEP flap (1.0%). The rate of fat necrosis was higher in the PAP flaps (40.7%) than in the DIEP flaps (17.8%) during ultrasound. CONCLUSION In our study, we found that PAP flap reconstruction tended to be performed in patients who were younger with lower BMIs compared with the DIEP flap. Successful reconstructive outcomes were observed in both the PAP and DIEP flaps; however, a higher rate of necrosis was observed in the PAP flap compared with the DIEP flap.

Abstract
BACKGROUND Acellular dermal matrix (ADM) is generally used on implant-based breast operations; However, it can increase surgical site infection. Many immersion solutions are applied to ADM, however, the most effective solution is unknown. The purpose of this study is to determine the effect of different solutions on the biofilm formation and mechanical properties of ADM. METHODS Aseptic porcine-derived ADMs were immersed in 5 different solutions for 30 min; sterile normal saline, 10% povidone-iodine, 0.5% chlorhexidine, antibiotics (cefazolin, gentamicin, and vancomycin), and taurolidine. They are transferred to 10 ml suspension of methicillin-sensitive/resistant Staphylococcus aureus (MSSA/MRSA) or Staphylococcus epidermidis and an overnight culture was performed. After rinsing and sonication to obtain the biofilm on ADM, colony forming unit (CFU) was measured. In addition, the maximum load before ADM deformation and the elongation length of ADM at the start of the maximum load was determined. RESULTS Regardless of strains, povidone-iodine, chlorhexidine, and taurolidine group had lower CFUs than the saline group with statistical significance. Meanwhile, the antibiotics group did not show statistical difference from the saline group. Moreover, only taurolidine group showed higher tensile strength (MRSA, p = 0.0003; S. epidermidis, p = 0.0023) and elongation length (MSSA, p = 0.0015) than the saline group. The antibiotics and chlorhexidine group yielded lower tensile strength and elongation length than the povidone-iodine and taurolidine groups. CONCLUSIONS It was suggested that the 10% povidone-iodine or taurolidine solution is effective. In contrast, the antibiotics solution could be considered as an effective intraoperative solution.

Abstract
Background Brassiere cup size is defined as the difference in chest circumference between the inframammary fold and the fullest part of the breast. However, a large number of women are not aware of the correct definition and are prone to wearing incorrectly-sized brassieres. In this report, the authors compared the cup size of worn brassieres and the actual measurement. Methods This study was a retrospective review of patients who had undergone breast reconstruction operation between May 2020 and June 2021. All patients who visited the plastic surgery clinic for breast reconstruction were inquired about their cup size, and their breast circumferences were measured. The patient demographic information, ptosis grade, mastectomy specimen weight, measured breast circumference, and known cup size were analyzed. Results Overall, 163 women were included. Notably, 92 of 163 patients (56.4%) were wearing a correctly-sized brassiere. Patients were more likely to wear a correctly-sized brassiere as the cup size became smaller. Moreover, patients with A-cup breasts tended to wear larger brassieres, whereas patients with B and C-cup breasts tended to wear smaller brassieres than their actual breast cup size. Conclusions Approximately one in two women do not know their correct brassiere cup size. Women tend to wear a brassiere of the wrong size as their cup size becomes larger. Therefore, it is important for surgeons to be aware of their patient's brassiere wearing habit and their perception when a surgery, such as augmentation or reconstruction, is planned.

Abstract
This study aimed to evaluate the results of magnetic resonance imaging (MRI) surveillance of implant-based breast reconstruction in patients with breast cancer. Methods This retrospective observational study analyzed patients who underwent implant-based breast reconstruction and MRI surveillance by a single surgeon from March 2011 to December 2018, in a single center. All patients were informed about the recommendation of the Food and Drug Administration for MRI surveillance, and they choose to undergo MRI 3 years after surgery. Results The compliance rate for MRI surveillance was 56.5% (169/299). MRI surveillance was performed at a mean of 45.8 (4.04 years) ± 11.5 months after surgery. One patient (0.6%) showed an abnormal finding of an intracapsular rupture of the silicone implant. Conclusions MRI surveillance for implant rupture in implant-based breast reconstruction showed a low incidence of silent implant rupture (0.6%), whereas the compliance of MRI was relatively high (56.5%). These results raise questions about whether taking an MRI in 3-4 years is suitable for imaging surveillance of breast silicone implants. Screening recommendations should be more evidence-based, and more studies are needed to prevent unnecessary screening and patient burden.

Abstract
The issue of breast implant-associated anaplastic large cell lymphoma in 2019 has resulted in the discontinuation of textured breast implants and resumption in the use of smooth round implants. However, in the field of breast reconstruction, long-term follow-up data for direct-to-implant reconstruction using smooth round implants is insufficient. This retrospective study aimed to evaluate the long-term outcomes of breast reconstruction using smooth round implants. This study included 185 patients (208 breasts) who underwent smooth round implant-based immediate breast reconstruction between 2007 and 2018. Their demographic information and surgical and oncological data were collected. Early (within 90 days) and late (after 90 days) complications, reoperations, implant maintenance, and the survival rate were analyzed to evaluate the long-term outcomes and identify the related factors. The mean follow-up period was 112.08 months. The most common early complications were skin necrosis (9.13%) and infection (3.85%). The factors influencing the development of early complications were the mastectomy specimen weight (237.14 ± 114.84 cc and 298.04 ± 141.53 cc for no complication and any complication, respectively; p = 0.0123) and implant volume (222.79 ± 77.76 cc and 264.48 ± 89.03 cc for no complication and any complication, respectively; p = 0.0082). The most common late complication was capsular contracture (13.46%). Approximately 91.35% of the implants were maintained during the follow-up period. The factors affecting the development of early complications and implant maintenance were the mastectomy specimen weight and implant volume. This study provides information on long-term follow-up results useful in cases where only smooth round implants are available, which can then serve as a basis for future related studies.

Abstract
Loss to follow-up is inevitable in retrospective cohort studies, and patients are lost to follow-up after direct-to-implant reconstruction despite annual follow-up recommendation. We analyzed more than 500 patients to analyze the rate of loss to follow-up to plastic surgery and to investigate the factors affecting it. A retrospective review of patients who underwent direct-to-implant reconstruction between July 2008 and August 2016 was performed. Loss to follow-up to plastic surgery was defined as a difference of ≥24 months between the total and plastic surgery follow-up. The rate of loss to follow-up and associated factors including patients' demographics, surgery-related variables, oncological data, and early and late complications were analyzed. Of 631 patients who underwent direct-to-implant reconstruction, 551 patients continued visiting the hospital for breast cancer-related treatment. Of the 527 patients who were eligible for the study, 157 patients (29.8%) were lost to plastic surgery follow-up. Surgery-related variables, early complications, cancer stage, and adjuvant therapies were not significantly different. Younger age was significantly associated with loss to follow-up in univariate analysis. However, logistic regression revealed that a long total follow-up period, distant metastasis, and absence of late elective complications were significant factors contributing to follow-up loss. Late elective complications such as malposition, capsular contracture, and mastectomy flap thinning were more common in the follow-up group (48%) than in the loss to follow-up group (22%). Follow-up loss after direct-to-implant reconstruction was not associated with specific demographic or surgery-related variables, and postoperative courses significantly affected the loss to follow-up.

Abstract
The impact of locally recurrent breast cancer on reconstructed breasts remains largely unknown. Therefore, this study aimed to investigate the incidence of reconstruction loss due to local recurrence in patients who underwent nipple-sparing mastectomy with immediate reconstruction for breast cancer and to identify potential recurrence-associated risk factors for loss of index reconstruction. The records of 1,696 patients who underwent nipple-sparing mastectomy with immediate reconstruction between March 2003 and December 2016 at a single institution were reviewed. Among them, 128 patients with local breast cancer recurrence as the first event were analyzed. The primary outcome was loss of reconstruction due to local breast cancer recurrence. Reconstruction loss was classified as partial flap loss with breast distortion, complete flap loss, or implant loss during salvage treatment of local recurrence. Reconstruction loss occurred in 21 of the 128 patients (16%). Reconstruction loss rates were 20% for autologous and 9.5% for implant-based reconstruction (P = 0.204). Multivariate analysis showed that recurrent tumor size > 2.0 cm and multifocal recurrence were independent factors associated with an increased risk of reconstruction loss. Moreover, age ≥ 50 years at the time of recurrence diagnosis, recurrent tumor size > 2.0 cm, and multifocal recurrence were independently associated with complete flap/implant loss in the multivariate analysis. The incidence of reconstruction loss due to local breast cancer recurrence after nipple-sparing mastectomy with immediate reconstruction was low in this study. Age ≥ 50 years at recurrence diagnosis and the extent of local recurrence independently affected reconstruction loss. To detect recurrence early, careful follow-up through regular ultrasonography or magnetic resonance imaging at the reconstruction site is important.

Abstract
Abstract
Background The difficulty of elevating a deep inferior epigastric perforator (DIEP) flap largely depends on the intramuscular course of the vessel and the perforator. Previous studies, however, have lacked histologic descriptions of the vessels and surrounding structures. The present study analyzed the histologic aspects of the deep inferior epigastric vessels and perforators, focusing on their perivascular relationships with muscle fibers.
Methods The abdomen of a cadaver was histologically evaluated to identify intramuscular deep inferior epigastric vessels. Tissue samples were stained with hematoxylin and eosin and with Masson trichrome stain to visualize fibrous components. Twenty-one DIEPs from 12 patients were also evaluated to determine the histologic aspects of the perivascular structure. In the cross-section of each perforator and adjacent tissue, the perforator-to-muscle distance and trichrome-stained area were measured, and the correlation of the perforator size with the perforator-to-muscle distance and the percent collagenous portion of the distance were determined.
Results Histologic analysis showed that the deep inferior epigastric vessels and perforators were encased by perimysial connective tissue and were not in direct contact with the muscle fibers. The smaller perimysia branched out from the larger perimysia, forming an interconnecting network structure. Correlation analysis showed that larger vessels had more collagenous portions in the perimysial structures (Spearman's ρ = 0.537, p = 0.012).
Conclusion The deep inferior epigastric vessels and perforators reside in a perimysial fibroadipose tissue network. This may provide surgeons with a microscopic perspective during DIEP dissections.
Clinical Relevance Statement Having an idea of the perforator anatomy in microscopic level can help us to perform safer perforator dissections.

Abstract
BACKGROUND The internal mammary system provides the recipient vessel of choice in free autologous tissue breast reconstruction. However, left internal mammary veins (IMVs) are smaller than right IMVs, thus raising questions about their reliability. Here we analyzed right and left breast deep inferior epigastric perforator (DIEP) flap reconstruction performed by an experienced versus less experienced surgeon and hypothesized that less experienced surgeons might encounter difficulty in cases of smaller left IMVs. METHODS We respectively reviewed the charts of 714 DIEP flap breast reconstructions performed by an experienced surgeon (>15 years' DIEP flap experience) and 231 performed by a relatively inexperienced surgeon (<4 years' DIEP flap experience). Reconstructions requiring microvascular revisions were compared with nonrevision controls, and left-side reconstructions were compared with right-side controls. RESULTS Preoperative risk factors were not significantly different between the left and right cohorts for either surgeon. The experienced surgeon performed 17 microvascular revisions (2.4%), including 9 left (52.9%) and 8 right (47.1%). The less experienced surgeon performed 7 microvascular revisions (3.0%), all left. The left- and right-side revision rates were 2.4% and 2.3% for the experienced surgeon versus 6.1% and 0% for the less experienced surgeon, respectively, with a higher rate for the left side (P = 0.0299). CONCLUSIONS The left-side microvascular revision rate was higher for the less experienced surgeon. Considering that left IMVs are smaller, less experienced surgeons should carefully perform left-side free flap breast reconstructions and be prepared to convert to thoracodorsal recipient vessel use.

Abstract
Abstract
Background Contralateral perfusion of zones II and IV is critical to estimate the amount of fat necrosis and determine intraoperative flap sacrifice during autologous breast reconstruction. We aimed to determine whether perfusion of the contralateral side was affected by the peak flow velocity in the feeding vessels in the deep inferior epigastric artery (DIEA) perforator free flap reconstructions.
Methods This was a retrospective review of patients who received DIEA perforator flap for autologous breast reconstruction from February to July 2020. Intraoperative indocyanine green (ICG) angiography and measurement software (Image J) were used to validate the perfusion of the contralateral side of the flap. Peak flow in the vessels was measured with duplex color Doppler and linear correlation was used to analyze the association between perfusion and blood flow velocity.
Results Forty-two patients received a DIEP flap. The average age of the patients was 48.5 years, and body mass index was 23.84 kg/m2. Peak flow velocity of the internal mammary artery (IMA) was significantly higher than that of the DIEA (p <0.05). Contralateral perfusion confirmed by ICG angiography was higher in the IMA than in the DIEA (p <0.05). A linear correlation was found between peak speed (p = 0.045) and ICG perfusion length (p = 0.00003).
Conclusion The status of flap perfusion depends on the feeding vessel. The velocity of blood flow between IMA and DIEA is different, and the flap perfusion varies accordingly. Therefore, ICG angiography should be performed after anastomosis at the recipient site for an accurate assessment.

Abstract
BACKGROUND AND OBJECTIVES Despite advances in medicine, infection at the surgical site is an impregnation problem that most surgeons confront. Although studies on the seasonality of infection have been conducted in various areas, no study has confirmed the relationship between seasonal temperature and infection after breast reconstruction. METHODS From 2008 to 2018, a retrospective study was conducted on patients who underwent implant-based breast reconstruction. Patient demographics, intraoperative data, postoperative data, and temperature information were collected. Temperature differences between cases with and without infection were examined. The differences in the incidence and risk of infection by season were estimated according to the hot season (July to August) and the nonhot season (September to June). RESULTS Of the 460 cases enrolled, 42 cases developed an infection. Among them, 15 (35.71%) cases developed infection during the hot season (P = 0.003). According to the logistic regression model, the risk of infection was 2.639 times higher in the hot season than in the nonhot season (95% confidence interval, 1.282-5.434; P = 0.008). When the temperature was higher than 25°C, the risk of infection increased by 45.2% for every 1°C increase, which was statistically significant (odds ratio, 1.452; 95% confidence interval, 1.198-1.76; P < 0.001). CONCLUSION In conclusion, the hot season or average temperatures higher than 25°C increase the risk of infection in patients undergoing implant-based breast reconstruction. It is essential to focus on skin hygiene during the healing of the incision site.

Abstract
BACKGROUND AND OBJECTIVES Despite expander-based breast reconstruction being used as a reliable reconstruction method, implant removal due to wound dehiscence and infection still occurs in 0.5% to 15% of cases. This study aimed to compare the outcomes of the new inframammary fold (IMF) incision approach with previous incision in second-stage operation of expander-based 2-stage breast reconstruction. METHODS Patients who underwent expander-based 2-stage breast reconstruction between February 2014 and May 2019 were included. After expander inflation, patients undergoing second-stage reconstruction were divided into the previous incision and IMF incision groups and their outcomes were compared. Propensity score matching analysis was performed to compare postoperative 1-year results. RESULTS The previous incision and IMF incision groups comprised 79 and 31 patients, respectively. There were no intergroup differences in general demographics or intraoperative data, except for total inflation volume (426.87 ± 102.63 mL in the previous incision group and 375.48 ± 94.10 mL in the IMF incision group, P = 0.017). Wound dehiscence occurred in 12 and 0 cases in the previous and IMF incision groups, respectively (P = 0.018). Implant removal was performed due to dehiscence in 9 cases (8.18%) and 0 cases (0%) in the previous and IMF incision groups, respectively (P = 0.049). In 1-to-1 propensity score matching analysis, the IMF incision group showed better results at 1-year follow-up (odds ratio: 0, 95% confidence interval: 0-1.09; P = 0.063). CONCLUSIONS The IMF approach is a safe method for replacing the expander with an implant, with lower incidence of wound dehiscence and implant explantation.

Abstract
We report a case of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), which had a history of spontaneous resorption of late seroma before diagnosis. A 47-year-old woman with a history of augmentation mammoplasty with round textured implants in January 2013 presented with a swelling on her right breast 6 years later, which was diagnosed as late seroma with suspected intracapsular rupture using ultrasonography (USG). Although aspiration was not done at the time of the initial USG, the seroma resolved spontaneously within weeks. A further workup proceeded with USG-guided aspiration followed by magnetic resonance imaging. Cytology of the aspirated fluid showed atypical cells. Cell block cytology and immunohistochemical staining confirmed the diagnosis of BIA-ALCL. En bloc resection with total capsulectomy and explantation was performed as curative surgery. Pathologic stage pT2N0M0 was confirmed and the patient was followed up without further treatment. Although the classic presentation of BIA-ALCL is known as late persistent seroma, an atypical manifestation such as spontaneous resorption may occur, as in the current case. A high level of suspicion and a thorough investigation with appropriate modalities will make it possible to detect this rare and potentially devastating disease.

Abstract
Background Few data are available on the risk factors of locoregional recurrence (LRR) after neoadjuvant chemotherapy (NACT) and immediate breast reconstruction (IBR) in breast cancer. Herein, we evaluated the factors predicting LRR in a large series of patients who underwent either nipple- (NSM) or skin-sparing mastectomy (SSM) with IBR after NACT. Methods We retrospectively analyzed 609 breast cancer patients who underwent NACT and NSM/SSM with IBR between February 2010 and June 2017. Factors associated with an increased risk of LRR were analyzed by univariate (chi-square or Fisher's exact test) and multivariate (Cox proportional hazard regression model) analyses. Results During a median follow-up of 63 months, LRR as the first event occurred in 73 patients, and the 5-year cumulative LRR rate was 10.8%. Multivariate analysis revealed post-NACT Ki67 ≥ 10% [hazard ratio (HR), 2.208; 95% confidence interval (CI), 1.295-3.765; P = 0.004], high tumor grade (HR, 1.738; 95% CI, 1.038-2.908; P = 0.035), and presence of lymphovascular invasion (LVI) (HR, 1.725; 95% CI, 1.039-2.864; P = 0.035) as independently associated with increased LRR risk. The 10-year LRR rate was 8.5% for patients with none of the three associated risk factors, 11.6% with one factor, 25.1% with two factors, and 33.7% with all three factors (P < 0.001). Conclusions Post-NACT Ki67 ≥ 10%, high tumor grade, and presence of LVI are independently associated with an increased risk of developing LRR after NACT and NSM/SSM with IBR. Future prospective trials are warranted to decrease the risk of LRR in patients with associated risk factors.

Abstract
PURPOSE Prosthetic breast reconstruction in the prepectoral plane with acellular dermal matrix (ADM) support has been gaining popularity and the use of robotic assistance could enhance this procedure. This study introduces robot-assisted prosthetic breast reconstruction using the anterior tenting method. METHODS Sixteen patients (16 breasts) undergoing surgery from July 2019 to April 2020 were included in this study. The breast oncology team performed mastectomies with direct-to-implant (DTI) reconstruction using the da Vinci XiTM (Intuitive Surgical Corp., Sunnyvale, CA, USA) system. The prepectoral plane anterior tenting method using ADM was performed. RESULTS Of the 16 patients, 14 underwent a nipple-sparing mastectomy and two underwent a skin-sparing mastectomy. The average patient age was 44.9 years, body mass index (BMI) was 22.9 kg/m2, and mastectomy weight was 367.6 g. The breast oncology team had an average operating time of 194.7 minutes, and the plastic surgery team had an average operating time of 80.8 minutes. The average postoperative drainage was 943.6 mL, and minor complications occurred in two patients. CONCLUSION With the robot, only a small incision of approximately 4.5 cm is necessary and areas that are not readily visible, such as the side of the axilla, can be accessed during the surgery. Using a smaller ADM size, the implant pocket under the ADM can be easily created under a magnified view. Inframammary fold (IMF) restoration is also possible with robotic surgery and delayed bleeding from the pocket can be easily controlled.

Abstract
PURPOSE We compared oncologic outcomes between breast cancer patients who underwent immediate implant-based breast reconstruction (IBBR) and those who underwent autologous flap reconstruction (AFR) after neoadjuvant chemotherapy (NACT). METHODS The study group comprised 536 patients with primary breast cancer who underwent NACT followed by immediate IBBR or AFR. After propensity score matching, 138 patients in the IBBR group and 276 patients in the AFR group were selected for comparisons of locoregional recurrence-free survival (LRRFS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and breast cancer-specific survival (BCSS). RESULTS No significant differences were observed between the matched groups in locoregional recurrence rates (IBBR vs. AFR: 12.3% vs. 12%; P = 0.915) and distant metastasis (13% vs. 17%; P = 0.293). There was also no significant difference between the groups in LRRFS (P = 0.956), DFS (P = 0.606), DMFS (P = 0.283), or BCSS (P = 0.121). The 5- and 10-year LRRFS rates were 87.6% and 85.9% in the IBBR group, and 87.7% and 86.1% in the AFR group; the 5- and 10-year DFS rates were 79% and 77.5% in the IBBR group, and 77% and 75% in the AFR group; the 5- and 10-year DMFS rates were 85.9% and 85.9% in the IBBR group, and 83.2% and 81.8% in the AFR group; and the 5- and 10-year BCSS rates were 97.8% and 91.3% in the IBBR group, and 91.8% and 86% in the AFR group, respectively. CONCLUSIONS In this propensity score-matched analysis of oncologic outcomes in breast cancer patients who underwent immediate reconstruction after NACT, no significant differences were observed between the IBBR and AFR groups.

Abstract
Nipple-spring mastectomy (NSM) with immediate breast reconstruction is being increasingly used in the treatment of breast cancer [1]. However, there are limited available data on the prognostic implications of locoregional recurrence (LRR) following this surgical procedure. This article is a supplementary resource of the original research article by Wu ZY et al. entitled "Locoregional Recurrence Following Nipple-Sparing Mastectomy with Immediate Breast Reconstruction: Patterns and Prognostic Significance" [2] and presents data regarding the subsequent distant metastasis following the first LRR, as well as the prognoses for isolated local recurrences according to the site of recurrence after NSM and immediate breast reconstruction for primary breast cancer. Data from a total of 1,696 patients with primary breast cancer who underwent NSM with immediate reconstruction from March 2003 to December 2016 at the Asan Medical Center, Seoul, Korea, were retrospectively reviewed. An LRR as the first event was found to have developed in 172 patients. Among these, 117 cases (6.9%) involved isolated local recurrence, including 52 cases (3.1%) of nipple-areola complex recurrence, 41 cases (2.4%) of skin/subcutaneous recurrence, and 24 cases (1.4%) of chest wall recurrence. Kaplan-Meier survival analysis and the log-rank test were performed to compare the subgroups of local recurrence. In 172 patients with LRR, subsequent distant metastases were observed in 30 cases (17.4%). Our data may be helpful for conducting further in-depth investigations on salvage treatment options in patients with LRR following NSM and immediate breast reconstruction.

Abstract
INTRODUCTION There are limited available data on the prognostic implications of locoregional recurrence (LRR) after nipple-sparing mastectomy (NSM) and immediate reconstruction. In this study, we investigated the patterns and prognosis associated with LRR following this treatment approach for breast cancer. METHODS A total of 1696 patients with primary breast cancer who underwent NSM with immediate reconstruction from March 2003 to December 2016 were retrospectively analyzed. Post-recurrence disease-free survival (DFS) and distant metastasis-free survival (DMFS) rates were calculated using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate analyses using the Cox proportional hazards model were performed to evaluate the prognostic factors associated with the DFS and DMFS. RESULTS After a median follow-up period of 84 months, we identified 172 patients (10.1%) with an LRR as the first event. The 5-year post-recurrence DFS rates for the nipple-areola complex recurrence (NCR), skin or subcutaneous recurrence/chest wall recurrence (SCR/CWR), and regional recurrence (RR) groups were 89.1%, 73%, and 59.4%, respectively (P = 0.009), and the 5-year post-recurrence DMFS rates for the NCR, SCR/CWR, and RR groups were 96%, 82.8%, and 59.7%, respectively (P < 0.001). In multivariate analysis, a time to LRR ≤2 years (P = 0.016) and the site of LRR (P = 0.022) were significantly associated with the post-recurrence DFS. CONCLUSIONS NCR is more likely to be detected as a non-invasive recurrence and is associated with more favorable overall outcomes than other LRR types. The interval to LRR and its site of onset seem to be associated with the prognostic outcomes.

Abstract
BACKGROUND Cancer recurrence after breast-conserving therapy is most often managed by salvage mastectomy. Successful breast reconstruction immediately after salvage mastectomy, however, remains challenging because the reconstruction is performed on previously irradiated breast tissue. METHODS Records of patients who underwent breast reconstruction from June 2010 to June 2019 were reviewed, including their demographic characteristics, methods of breast reconstruction, and early and late outcomes. Deep inferior epigastric perforator (DIEP) flaps and direct-to-implant (DTI) reconstructions following salvage mastectomies were compared with reconstructions following completion or primary mastectomies. Patients who underwent reconstruction followed by postmastectomy radiotherapy (PMRT) and patients followed up for less than 6 months were excluded. RESULTS DIEP flaps in 27 breasts that underwent salvage mastectomy were compared with DIEP flaps in 32 breasts that underwent completion and 564 that underwent primary mastectomy. Rates of early complications, including microsurgical revision and total flap loss, and of late complications (>6 months after surgery), including fat necrosis and flap volume loss, did not differ significantly. DTI reconstruction in 20 breasts that underwent salvage mastectomy was compared with DTI reconstruction in 12 breasts that underwent completion and 351 that underwent primary mastectomy. Wound healing problems, including wound dehiscence and delayed wound healing (15% vs. 2.6%, P = 0.0022), and capsular contracture (30% vs. 5.4%, P = 0.0000), were significantly more frequent in breasts that underwent salvage than primary mastectomy. CONCLUSIONS DIEP flap is a successful reconstruction option after salvage mastectomy. DTI reconstruction is associated with higher rates of wound healing problems and capsular contracture after salvage than after primary mastectomy.

Abstract
BACKGROUND Additional second vessels may be required to handle multiple flaps used to add breast volume, boost blood flow for supercharging, or use salvage recipient vessels. In these situations, retrograde internal mammary vessel flow can be used although this causes doubts and concerns. PATIENTS AND METHODS Forty sides of the chests of 20 fresh cadavers with intact thoracic cages and internal mammary veins (IMV) were used in the study. IMV valve numbers and locations were checked, and the bifurcation was confirmed. A retrograde fluorescent angiography and a saline infusion test were followed to confirm flow direction. RESULTS Twenty-eight vessels were identified in 40 sides of the chest; of them, 45% had no valves. A mean 0.7 valves per chest side were identified; 23 (82.1%) of 28 valves were located above the second intercostal space (ICS). A mean 1.76 communicating veins were found between the IMV bifurcation. In all cadavers, a crossing vein connecting the left and right medial IMV was confirmed just below the xiphoid process. Fluorescent angiography and a saline infusion test proved that the retrograde flow was caudal through the bifurcated IMV to the communicating, intercostal, and crossing veins. CONCLUSION The IMV valve was present in 55% of our subjects and located concentrically above the second ICS level. It is highly unlikely that the retrograde flow was disturbed because the retrograde anastomosis level was below the second ICS. Furthermore, the bifurcation, intercostal, and crossing veins across the xiphoid process enabled valve-less detour flow. Thus, retrograde IMV flow is considered safe.

Abstract
BACKGROUND Seroma is a recognized complication encountered at the reconstructed breast and donor site after abdominal-based breast reconstruction. Seroma is caused by lymphatic channel disruption and the formation of a large space between the deep fascia during flap elevation. Surgical techniques to preserve the lymphatics and secure the closure of the donor site can reduce seroma formation. This study investigated the safety and effectiveness of the diuretic hydrochlorothiazide at reducing interstitial fluid accumulation and seroma formation during deep inferior epigastric perforator (DIEP) flap breast reconstruction. METHODS Sixty patients with breast cancer who underwent skin- or nipple-sparing mastectomy and DIEP flap reconstruction were enrolled between August 2016 and June 2017. The patients were randomly assigned to receive either 25 mg per day of hydrochlorothiazide from the second to the twentieth day after surgery (treatment) or no diuretic (control). The clinicopathological characteristics, drainage time, and drainage volume were statistically compared between the two groups. RESULTS The average total drainage volume at the donor site was 291 mL in the treatment group and 434 mL in the control group (p = 0.003). The differences in body mass index and flap weight between the two groups were not statistically significant (p = 0.879 and p = 0.963, respectively). No hypotension or electrolyte imbalance was noted during the follow-up. CONCLUSIONS Intake of 25 mg per day of hydrochlorothiazide tablets effectively reduced the total abdominal drainage volume and removal time of indwelling drains. However, the adverse effects should be further investigated in a large population and multiracial cohort before using hydrochlorothiazide for seroma prevention.

Abstract
Purpose Skin grafts have been widely used in managing extensive chest wall defects after mastectomy for advanced breast cancer. However, their durability and tolerability to radiotherapy is still controversial. A thoracoabdominal (TA) flap with a few technical refinements can safely transfer a larger flap while minimizing complications. Methods From January 2007 to February 2018, a retrospective review was performed to compare 2 groups after wide breast excision: skin graft group (group 1) and lateral-based, single vertical incision rotation-advancement TA flap (group 2). Patients' demographics, operative details, complications, hospital stay, postoperative outpatient visits, cost, and start of adjuvant therapy were analyzed between the 2 groups. Results During the study period, 34 patients received skin graft and 41 patients received TA flap. group 2 had a shorter hospital stay (6.41 ± 2.64 days vs. 12.62 ± 4.60 days, P < 0.001) and shorter time to complete wound healing (29.27 ± 18.68 days vs. 39.24 ± 27.70 days, P = 0.03) than group 1. There was also a difference in the period from surgery to initiation of adjuvant therapy (group 1, 45.04 days ± 17.79 days; group 2, 37.07 ± 15.38 days, P = 0.073). Although limitation in shoulder motion was more frequent in group 2, limitation of motion for >1 year was observed in 4 patients in only group 1 (43.90% vs. 38.24%, P = 0.613). Conclusion TA flap has a simple design that minimizes concerns involving the donor site. Moreover, it does not require complicated procedures and allows for re-elevation whenever necessary. Finally, it guarantees faster wound recovery than skin graft with fewer complications.

Abstract
Background This study was conducted to evaluate the impact of choosing a particular recipient venous system on venous patency and flap survival in 652 head and neck free flap reconstructions.
Methods A retrospective review was performed. Patient factors investigated included: age, sex, type of flap, tumor location, history of radiation, presence of previous neck dissection, tumor stage, and any underlying disease. Data related with recipient vein including the number of anastomosis, the repair technique, the type of recipient vein, and the configuration of selected venous system were examined. The impact of patient factors and parameters related with recipient vein on the venous patency and flap survival were analyzed using bivariate and multivariate analyses.
Results Of 652 free flaps, 36 flaps (5.5%) were re-explored due to venous congestion and 28 flaps (77.8%) were salvaged. The overall survival rate of total free flaps was 98.8%. The type of recipient venous system was found to be an insignificant factor with respect to venous congestion and flap survival in multivariate analysis. A history of radiation treatments was the only factor associated with a higher risk of venous compromise (odds ratio [OR] = 13.138, p < 0.001) and a lower rate of flap survival (OR = 20.182, p = 0.002).
Conclusion The selection of recipient venous systems has no impact on venous patency and flap survival. History of radiation treatment was the only factor associated with venous congestion and flap failure. Since no single method can ensure a successful reconstructive result, selecting the optimal recipient vein should be based on individual patient factors and the surgeon's experience.

Abstract
BACKGROUND The low deep inferior epigastric perforator (DIEP) flap was first introduced in 2016 as it had aesthetic advantages over the conventional DIEP flap. With our experience of over 100 low DIEP flap procedures to date, we have conspicuously lowered complication rates and established more definitive criteria to select proper candidates. METHODS We analyzed 103 patients who underwent breast reconstruction with the low DIEP flap at our hospital between May 2014 and June 2018. Demographics, patient selection criteria, flap specifics, surgical outcomes including postoperative complications, and the location of the abdominal scar and umbilicus were reviewed retrospectively. RESULTS The mean patient age was 46.7 years, and the average body mass index was 23.7 kg/m2. A low DIEP with an average weight of 377 g was utilized within 6 hours 17 minutes in this cohort. There was no significant difference in the rate of venous congestion or fat necrosis compared with the conventional DIEP flap. The average distance from the pubic hairline to the abdominal scar was 0.6 cm and from the anterior superior iliac spine to the abdominal scar was -0.4 cm. The postoperative location of the umbilicus was 7.0 cm above the pubic hairline. CONCLUSION The low DIEP flap is not only a reliable option for a breast reconstruction but is an aesthetically superior approach with a lower abdominal scar and natural umbilicus. Patients may benefit from this technique if prudently selected by computed tomography (CT) angiography. A perforator that is larger than 1 mm in diameter and well enhanced on CT angiography from the division of the external iliac artery to the abdominal skin particularly in the intramuscular course should be selected.

Abstract
BACKGROUND Although guidelines to prevent surgical site infections (SSIs) were published more than a decade ago, prophylactic antibiotics are still used subjectively in clinical practice. In this study, we evaluated the safety of single-dose preoperative intravenous antibiotics without postoperative antibiotics in the field of clean wound surgery performed under local anesthesia. We also surveyed the present clinical conditions for prophylactic antibiotic use in the plastic surgery departments of training hospitals in Korea. METHODS A total of 360 consecutive patients who underwent clean wound surgery under local anesthesia in an outpatient clinic from March 2018 to October 2018 were reviewed. In the study group, a single surgeon administered first-generation cephalosporins intravenously within 1 hour of skin incision and did not prescribe additional antibiotics. In the control group, 2 other surgeons prescribed oral first-generation cephalosporins postoperatively for 2 to 3 days without preoperative antibiotics. A telephone survey about perioperative antibiotic regimens was conducted at the departments of plastic surgery in training hospitals. RESULTS There were 128 patients in the study group and 232 patients in the control group. There were no significant differences between the 2 groups regarding SSIs and other surgical complications. A total of 41 training hospitals answered the survey and every hospital had protocols of prescribing postoperative oral antibiotics routinely at the time of discharge with a mean duration of 3.9 days. Only 11 hospitals (26.8%) prescribed parenteral antibiotics before surgery as well as postoperative oral antibiotics. CONCLUSION Intravenous injection of single-dose first-generation cephalosporins 1 hour before surgery without postoperative antibiotics did not increase the incidence of SSIs compared with the usual practice of giving only postoperative antibiotics prescription for 2 to 3 days in cases of clean wound surgery performed under local anesthesia. Proper antibiotic prophylaxis should be performed by surgeons in training hospitals without hesitation.

Abstract
Deep inferior epigastric perforator (DIEP) flap is associated with less donor site morbidity than transverse rectus abdominis myocutaneous flap. However, abdominal muscle atrophy and donor site complications caused by denervation during pedicle dissection cannot be avoided. This retrospective study investigated the change in the rectus abdominis muscle volume after DIEP flap harvest. Of 395 patients who underwent unilateral DIEP flap breast reconstruction between August 2007 and July 2017, 25 patients with >2-year postoperative abdominal computed tomography data were evaluated. Preoperative and postoperative images of the abdominal muscle after pedicle dissection and the nonoperated side were compared. The volume of the muscles from the lower margin to the umbilicus was determined by using OsiriX image analysis application. The muscle volumes on the side of pedicle dissection decreased from 72.63 ± 23.29 cm3 preoperation to 53.09 ± 16.93 cm3 postoperation (p < 0.001). The corresponding volumes on the side without dissection were 73.29 ± 19.25 cm3 and 60.89 ± 18.79 cm3 (p < 0.001). The percentage of postoperative retained volume relative to the preoperative retained volume was 75.65% ± 19.18% on the pedicle dissection side and 84.65% ± 19.00% on the contralateral side. The 9% difference was not statistically significant (p = 0.10). No major abdominal complications were observed. Despite nerve injury during DIEP flap surgery, the volume loss of the involved and contralateral muscles did not differ. More than 75% of the abdominal muscle volume was retained. Muscle integrity was well maintained without any postoperative complications.

Abstract
BACKGROUNDS This study aimed to compare the oncologic outcomes of nipple-sparing mastectomy (NSM)/skin-sparing mastectomy (SSM) followed by immediate reconstruction with those of conventional mastectomy (CM) in young patients aged under 35 years old with breast cancer. METHODS We analyzed retrospectively 2889 patients who underwent mastectomy for breast cancer at Asan Medical Center from January 2003 to December 2008. We compared NSM/SSM followed by immediate reconstruction with CM in patients under 35 years old by analyzing clinicopathologic features, breast cancer specific survival rate (BCSS), distant metastasis free survival rate (DMFS), and local recurrence rate (LRR). RESULTS Out of a total of 2889 patients, we performed NSM/SSM in 118 patients and CM in 141 patients aged less than 35 years old. DMFS were 85.3% and 73.4% in NSM/SSM and CM, respectively (p = 0.001). BCSS were 90.7% and 73.0% in NSM/SSM and CM, respectively (p = 0.001). After adjusting for stage, there were no statistically significant differences between the two groups with respect to DMFS and BCSS. The type of surgery was not a prognostic factor in multivariate analysis for DMFS and BCSS (CM vs. NSM/SSM: DMFS HR = 0.67, p = 0.215; BCSS: HR = 0.66, p = 0.265). CONCLUSIONS Compared to CM, NSM/SSM followed by immediate breast reconstruction is oncologically safe and could be a viable surgical treatment in young patients under 35 years old with breast cancer.

Abstract
To evaluate the oncological outcomes of patients with breast cancer after nipple-sparing mastectomy (NSM)/skin-sparing mastectomy (SSM), followed by immediate reconstruction, as compared to conventional mastectomy (CM).SSM/NSM has been increasingly used to treat women with breast cancer who wish to preserve the overlying breast skin, but concern exist regarding its oncological safety due to the potential for residual breast tissue. We report our experience performing SSM/NSM for breast cancer treatment compared to CM with a long follow-up period.All consecutive patients who underwent mastectomy for breast cancer at Asan Medical Center between January 1993 and December 2008 were identified by retrospective medical chart review. The patients who underwent NSM/SSM, followed by immediate breast reconstruction with a pedicled transverse rectus abdominis musculocutaneous flap (TRAM), were compared to the patients who underwent CM in terms of breast-cancer specific survival (BCSS) rate, distant metastasis-free survival (DMFS) rate, and local recurrence (LR) rate.During the study period, 6028 patients underwent mastectomy for breast cancer. Of these, 1032 and 4996 underwent NSM/SSM with TRAM and CM, respectively. Their median follow-up durations were 94.4 (range, 8.1-220.2) and 110.8 (range, 6.1-262.0) months, respectively. Their 5 year BCSS rates were 95.4% and 88.1%, respectively (log-rank, P < .001). Their 5 year DMFS rates were 93.0% and 85.6%, respectively (log-rank, P < .001).Relative to CM, NSM/SSM, followed by immediate breast reconstruction, may be a viable and oncologically safe surgical treatment in selected patients with breast cancer.

Abstract
Background Breast reconstruction using deep inferior epigastric artery perforator (DIEP) free flap is widely used because of the advantages of minimizing donor-site morbidity, but it requires technical competency in vascular dissection. This study evaluated the influence of patient factors and vascular status on the time and speed of dissection of the vascular pedicle.
Methods DIEP free flap procedures were performed in 49 patients assigned to immediate or delayed reconstruction groups. Factors that significantly influenced the time required and the speed of dissection were evaluated.
Results The average total dissection time was 55.9 minutes (34.5 minutes for the intramuscular dissection and 21.4 minutes for the submuscular dissection). The dissection speed for the total vascular pedicle was 2.65 cm/10 minutes (1.71 cm/10 minutes for the intramuscular dissection and 4.30 cm/10 minutes for the submuscular dissection). The presence of a Pfannenstiel scar, length of the vascular pedicle in the intramuscular area, and the number of microclips used significantly correlated with the total dissection time.
Conclusion The length of the intramuscular pedicle, number of microclips used, and presence of a Pfannenstiel scar significantly correlated with the total dissection time of the vascular pedicle. An assessment prior to the surgery can reduce the time of operation and make it easier to elevate the flap.

Abstract
BACKGROUND Tissue transfer, such as use of the transverse rectus abdominis myocutaneous (TRAM) or deep inferior epigastric artery perforator (DIEP) free flaps, is considered a standard method. However, outcomes may vary among inset methods. Here we compared the aesthetic outcomes of breast reconstructions using vertical and horizontal flap inset methods. METHODS We, respectively, reviewed 274 patients who underwent unilateral post-mastectomy breast reconstruction using TRAM or DIEP free flaps between April 2006 and December 2013. Photographs (frontal and bilateral oblique views) obtained 6 months post-operatively were evaluated. Symmetry scores and regional volume discrepancy scores were compared between the vertical and horizontal inset groups. Symmetry scores were adjusted for 11 potential confounding factors on multivariate regression analysis. RESULTS The vertical inset method was associated with higher total symmetry scores, projection, and ptotic naturalness scores. On multivariate regression analysis, the inset method was an independent predictor of outcomes. Regional volume discrepancy score analysis showed a greater tendency for more symmetrical volumes in the upper, medial, and lateral poles with the vertical inset. CONCLUSION The flap inset method is one of the key determinants of aesthetic breast reconstruction outcomes. The vertical inset method was associated with superior aesthetic outcomes and enabled balanced distribution of flap volume to the four poles of the breast.

Abstract
BACKGROUND Numerous nipple reconstruction methods have been proposed including the use of local flaps and composite grafts, but most methods have shown a significant loss of projection. We combined a modified CV flap with a composite graft (nipple sharing) to maximize the projection and volume of the new nipple and reduce the size of the contralateral nipple. METHODS In total, 30 patients underwent nipple reconstruction using a combined method between January 2013 and November 2015. This technique was selected if the diameter of the contralateral nipple was large and the thickness of the skin was less than 2 mm. After the modified CV flap was created, a composite graft from the contralateral nipple was placed between the V flaps and the C flap. The loss of projection and the ratio of the new nipple to the contralateral nipple were evaluated 12 months after surgery. RESULTS Nipple reconstruction was successful in all cases. The projection at 12 months after reconstruction was 68% of the initial projection, and the mean projection ratio of the new nipple to the contralateral nipple was 0.81. There was no complication in the donor nipple; in fact, the shape was improved with nipple reduction, and the scar was inconspicuous. CONCLUSIONS Nipple reconstruction that combines a modified CV flap and composite graft can maximize the nipple projection and provide a chance for nipple symmetry as the two components will act synergistically.

Abstract
BACKGROUND The purpose of this study was to determine the risk factors associated with mastectomy skin flap necrosis during immediate reconstruction with TRAM or DIEP flaps. METHODS This study reviewed 1116 cases of immediate breast reconstruction over 10 years. Patients ranged in age from 29-76 years (average = 45.1 years), and had an average follow-up period of 65.6 months. Thirteen factors (age, BMI (body mass index), smoking habits, diabetes ptosis grade, midclavicle-to-nipple distance, neoadjuvant chemotherapy, free or pedicled flap, mastectomy method, surgeon, stage, axillary dissection, mastectomy weight) known to be associated with mastectomy flap necrosis were retrospectively analysed. The odds ratios of the risk factors were calculated using logistic regression analyses. RESULTS Mastectomy skin flap necrosis occurred in 247 cases (22.1%). Univariate regression analysis showed that the odds ratio of age, BMI, ptosis grade, midclavicle-to-nipple distance, free flap, mastectomy method, surgeon, stage, and mastectomy weight were significant and the odds ratios determined using multivariate analysis were significant for mastectomy method, surgeon, and mastectomy weight. CONCLUSION During breast reconstruction using abdominal tissue, the independent risk factors that affect mastectomy skin flap necrosis include the mastectomy method, surgeon, and the weight of the mastectomy specimen. Awareness of the impact of each risk factor will lead to the modification and individualisation of surgical techniques and continually improve outcomes.

Abstract
BACKGROUND The internal mammary artery (IMA) is one of the most popular recipients for microsurgical breast reconstruction. However, it is often separated into sleeve-like layers when it is handled. This study tried to explain this unique behaviour of the IMA through histologic observation. METHODS Nine pairs of IMAs and DIEAs were harvested and subject for haematoxylin-eosin and Verhoeff's elastic staining. Thickness of the tunica media and the number of elastic lamellae were compared. Samples of the IMA, the DIEA, and the thoracodorsal artery from another patient were observed through the transmission electron microscope to further show the structural differences. RESULTS The most notable difference was presence of multiple elastic lamellae in tunica media in the IMAs, which was barely present in the DIEAs. The mean number of elastic lamellae was 9.2 in the IMA group and 1.0 in the DIEA group (p < 10(-9)). A transmission electron microscope showed that the tunica media of the DIEA and the TDA was densely packed with smooth muscle cells, while the muscle cells distributed sparsely in the IMA. CONCLUSIONS The IMA is an elastic artery which is characterised by multiple layers of elastic lamellae while relatively lacking in smooth muscle cells. The wall of the IMA is easily dissected between the tunica media and the adventitia, or at the outer 1/3 of the tunica media. The inner structure is easily torn if microsutures do not engage the tunica adventitia.

Abstract
OBJECTIVES Successful management of post-resection bronchopleural fistula (BPF) is a challenge, and various loco-regional flaps have been used to directly cover or to enhance closure of the bronchial stump. The serratus anterior muscle (SAM) is one of the workhorse flaps, although its use as a musculocutaneous flap has been debated. Here, we present our early experience with serratus anterior musculocutaneous (SAMC) flaps for the obliteration of BPF. METHODS A retrospective review of patients with surgical management of BPF from April 2005 to June 2014 was performed. A de-epithelized SAMC flap has replaced the conventional SAM flap since August 2013. Nine of consecutive former SAM flaps and 5 consecutive later SAMC flaps were identified. A detailed review of the SAMC flap cases was performed to describe medical and surgical history, BPF diagnosis and location, and the outcome of the flap surgery. RESULTS All five BPFs treated by SAMC flap were greater than 1 cm in diameter and all occurred on the right side. The leading primary diagnosis of a BPF was lung cancer, and the 4 lung cancer patients all underwent previous irradiation. The average size of the skin paddle was 19 × 6.6 cm(2), and the average volume of the skin paddle was 100.3 cm(3). Recurrence of the BPF was noted in 1 patient 6 weeks after surgery. In 4 of 5 patients, viable adipose tissue was confirmed by computed tomography scans. CONCLUSIONS The SAMC flap holds merits of a local flap such as short operation time, relative safety, no need of position change and faster recovery, with increased freedom of flap transfer and additional volume, thus widening surgical indication of the large, recalcitrant BPFs. We suggest that the SAMC flap could be safely harvested and used for management of a BPF or similar intrathoracic lesion when extensive flap length or bulk is required.
