Objective:To evaluate incision scars of transaxillary breast augmentation by different methods of scar assessment.Methods:A retrospective study was carried out on 30 patients (age range 20 to 50 years, with mean age of 32 years) who underwent endoscopic assisted transaxillary type Ⅰ dual plane breast implant augmentation by a same surgeon from August 2014 to November 2016. Scars were estimated by 3 methods which included Vancouver Scar Scale (VSS), Visual Assessment Scale (VAS) and patients' questionnaire.Results:VAS score for left side scars ranged from 0 to 8 and the median was 1. VAS score for right side scars ranged from 0 to 8.3 and the median was 1. A total of 48 scars were scored in the 0-2 point range, representing 80% of the 60 total. VSS score for left side scars ranged from 0 to 11.6 and the median was 0.8. VSS score for right side scars ranged from 0 to 11.3 and the median was 1.2. A total of 46 scars were scored in the 0-2 point range, representing 76.7% of the total 60 breats. The scores between VSS and VAS had significant statistical differences ( P<0.001). 80.0% of our patients regarded scars as unconspicuous or basically invisible in our questionnaire. Conclusions:The majority of transaxillary incision scars recover in favorable status with high patients satisfactory rate. VAS is a practical tool for evaluating transaxillary incision scars. The VSS score is not equivalent to the VAS score when grading scars only by photos.

Resumen Antecedentes: La cirugía de aumento mamario con lipoinjerto se ha incrementado debido a que evita usar prótesis. Es utilizado para aumentos moderados con fines estéticos, no retarda el diagnóstico de cáncer ni aumenta el riesgo de sufrirlo. Objetivo: Revisar nuestra experiencia en aumento mamario estético con lipoinjerto, en una sesión y con seguimiento superior a un año. Materiales y Método: Se diseñó una cohorte prospectiva de mujeres. Se excluyeron aquellas con alteraciones congénitas, mesenquimopatías y fumadoras. La lipoinyección se efectuó con principios de Coleman. Para la medición del volumen mamario preoperatorio se utilizó la aplicación Breast-V. Volumen de aumento, tasa de retención y tasa de aumento fueron calculados. Resultados: 73 pacientes fueron lipoinjertadas, 35 superaron seguimiento a un año. Volumen mamario inicial fue 219,5 ± 44,1 cc. Volumen de aumento fue 99,9 ± 29,8 cc, tasa de retención grasa injertada 41,4%, tasa de aumento del volumen mamario 48,1%. 41 pacientes presentaron imágenes posoperatorias: quistes 15 pacientes (36,6%); necrosis grasa 2 pacientes (4,9%); macrocalcificaciones 8 pacientes (19,5%); microcalcificaciones 1 paciente (2,5%), cuya biopsia fue negativa para malignidad. Discusión: El lipoinjerto mamario es un procedimiento seguro, con resultados adecuados cuando se realiza en una sesión y por el mismo cirujano, siguiendo principios de Coleman. El aumento porcentual es el índice más significativo para evaluar su éxito. Conclusiones: Lipoinyección mamaria en una sesión es una técnica segura que logra aumento moderado del volumen mamario. Es útil para aumentos moderados o corrección de asimetrías leves. No hay evidencia de que interfiera con el diagnóstico precoz del cáncer de mama.
Background: Lipograft breast augmentation has increased due to avoidance of prosthetics. It is used for moderate increases for aesthetic purposes, it does not delay the diagnosis of cancer or increase the risk of suffering it. Aim: To review our experience in cosmetic breast augmentation with lipograft, in one session and with a follow-up of more than one year. Materials and Method: A prospective cohort of women was designed. Those with congenital alterations, mesenchymopathies and smokers were excluded. Lipoinjection was carried out with Coleman's principies. The Breast-V application was used to measure preoperative breast volume. Volume of increase, retention rate and rate of increase were calculated. Results: 73 patients were lipografted, 35 had a one-year follow-up. Initial breast volume was 219.5 ± 44.1 cc. Volume increase was 99.9 ± 29.8 cc, grafted fat retention rate 41.4%, breast volume increase rate 48.1%. 41 patients presented postoperative images: cysts 15 patients (36.6%); fat necrosis 2 patients (4.9%); macrocalcifiations 8 patients (19.5%); microcalcifiations 1 patient (2.5%), whose biopsy was negative for malignancy. Discussion: The mammary lipograft is a safe procedure, with adequate results when performed in one session and by the same surgeon, following Coleman principles. The percentage increase is the most significant index to evalúate your success. Conclusions: Breast lipoinjection in one session is a safe technique that achieves a moderate increase in breast volume. It is useful for moderate magnification or correction of slight asymmetries. There is no evidence that it interferes with the early diagnosis of breast cancer.

Background@#In 716 Mongolian patients who had breast augmentation surgery at Perfect Clinic during 18 years. The purpose of this study evaluates Mongolians predictors of early and late outcome after primary breast augmentation surgery.@*Aims of study@#In this study, we aimed to clarify predictors of early and late outcome after breast augmentation surgery.@*Methods@#We selected patients who underwent breast augmentation implant surgery between 1999 and 2017. Development of hematoma was chosen for measure of early outcome and capsule contracture was chosen for measure of late outcome. Multivariable Cox proportional hazard regression and Kaplan-Meier estimations were used to clarify independent relationship between possible predictors and outcomes.@*Results@#A total of 716 patients were chosen and mean age was 32±7 years old. Hematoma was occurred in 43 patients (6%) and median time to hematoma was 3 days (IQR 1; 7).). According to the univariable analysis, every 1 year experience was associated with 9% decreased risk of hematoma development. (HR=0.91, 95% CI 0.84-0.99, p<0.05). Finally, Kaplan-Meier estimation was showed that hematoma free survival is higher in more experienced years and patients who had subpectoral muscle.(log rank p<0.01 and p<0.001, respectively). Capsule contracture was occurred in 38 patients (5.3%) and median time to capsule contracture was 10 months (IQR 3; 27). According to the univariable analysis, every 1 year increase of surgical experience is related to 9% decreased risk of capsule contracture (HR=0.81, 95% CI 0.75-0.88, p<0.001), and more textured implant type is associated with less capsule contracture (HR=0.47, 95% CI 0.34-0.66, p<0.001). </br> Multivariable hazard regression was revealed that implant type (HR=0.55, 95% 0.33-0.90, p<0.05) and surgical time (HR=1.00, 95% CI 1.00-1.01, p<0.001) were independently associated with capsule contracture after breast augmentation surgery (Table 4). Kaplan-Meier estimation was determined that capsule contracture free survival is higher in more experienced years and patients who had more textured implant and subpectoral muscle implant (log rank p<0.001, p<0.001 and p<0.001, respectively).@*Conclusions@#For breast augmentation surgery, implant type is independent predictor of capsule contracture and surgical experience is predictor for both hematoma and capsule contracture. Therefore, above mentioned predictors should be considered to prevent complications related to breast augmentation implant surgery.

Objective:To investigate the causes and treatment of implant malposition after breast augmentation surgery.Methods:A retrospective study was conducted to investigate the patients with implant malposition after breast augmentation treated or consulted in our department from January 2000 to December 2020. A total of 95 breasts in 74 patients were treated during the period. The age of the patients was from 19-50 years, with the mean of 31.2 years. Causes of these complications were analyzed and the patients were managed in different ways according to the times after primary breast augmentation.Results:Twenty-one malposition breasts occurred within one week after primary surgery, and 17 breasts were successfully treated with manual reduction and fixation. 4 breasts were treated with operation after failed with manual reduction. The patients had good and bilateral symmetric breast morphology during the 6 months follow-up after the second operation. 25 malposition breasts were treated from one week to one month after primary surgery. Reoperation was performed through the original incision, separating the adhesive cavity to reposition the implant. Those patients were successfully treated. No re-occurrence was detected at 6 months follow-up after treatment. 49 malposition breasts were treated more than 3 months after primary surgery. Excessive capsule wrapping the shifted implant was removed to recreate a fresh wound while the adhesive cavity was separated to reset the implant. Bandage fixation was necessary. 7 implants were exchanged. 2 breasts were over corrected and re-operated successfully.Conclusions:The causes of implant malposition at different time after breast augmentation are various. Different methods can be used for effective treatment.

Objective:To explore whether botulinum toxin A (BTX-A) can improve the retention rate of fat transplantation in fat breast augmentation.Methods:Each patient was divided into control side and experimental side according to the random number table in 14 patients studied. The experimental group received autologous fat and BTX-A combined transplantation on both sides of the breast, while the control side only received autologous fat transplantation. The fat was added with the same volume of normal saline as BTX-A in the control group. All patients were followed up and the effects of BTX-A were evaluated objectively via the comparison of the remained bilateral fat graft volumes that were obtained through a digital three-dimensional reconstructions technique. Moreover, the improvement of each breast appearance and complication were assessed by the physician and patients who were blinded to the recipient treatment assignment.Results:The outcome of the fat breast augmentation was evident for both groups at the follow-up with no evidence of fat embolism, vascular/nervous injury, infection and prolonged bruising. In one of the 14 patients (control group), fat liquefaction necrosis occurred in one side of the breast; after active treatment, it returned to normal, and three patients had different degrees of mass. The analysis on the three-dimensional reconstruction data and the assessments from both the physicians and patients showed significant differences in the fat graft retention volume between the BTX-A group (51.10±20.56)% and the control group (33.06±14.77)%. Nevertheless, there was no significant difference in the incidence of complications between the two sides.Conclusions:Autogenous fat breast augmentation is safe and effective. This study result has shown that BTX-A can significantly improve the retention rate of fat transplantation but cannot reduce the incidence of complications.

Objective:To investigate the preliminary effects of sub-pectoral fascial breast augmentation and reconstruction.Methods:Six patients (10 breasts) of mammary dysplasia, mastatrophy, prophylactic mastectomy, unilateral breast defect with contralateral mastatrophy were included in the study from Oct. 2019 to July 2021. The mean patient age was 29 years (range, 20 to 35 years). All the textured and smooth cohesive gel implants were inserted under pectoralis major fascia by endoscopic-assisted, incisions were including axillary, around areola and inferior mammary fold approaches. The prophylactic mastectomy cases were performed nipple sparing mastectomy and sub-pectoral fascial breast restoration with implants. The fat and fascia tissue were well reserved to give a satisfying coverage of the appropriate implant. Negative pressure drainage and moulding dressing were used after the surgery.Results:Ten breast augmentation and restoration with a mean implant size of 200 cc (range, 180-300 cc). Less immediate postoperative pain and bleeding were reported. Patients were followed up for an average of 10 months (range, 6 to 21 months). There were no cases of major malpositions, double-bubble and bottom out symptoms. The overall outcome was with better symmetry and satisfaction with time passed by, and no secondary surgical procedures needed.Conclusions:Primary and satisfactory results have been obtained in subfascial breast augmentation and restoration for indications. With the endoscopic-assisted accurate pectoral fascial dissection, and well reserved soft tissue coverage, this technique could avoid the pectoralis major muscle ablation and keep the advantages of sub-glandular plane.

Objective:To explore the effect of decision-making assistance during the implantation selection of breast augmentation patients to provide a reference for improving decision-making aids.Methods:From June 2018 to June 2020, the decision-making assistance programs were used in the Department of Plastic and Reconstructive Surgery, Shanghai Ninth People＇s Hospital for prosthesis selection in 51 breast augmentation female patients, aged 23 to 42 years, with an average of 31 years old. The BREAST-Q scale was applied to assess the postoperative results of augmentation patients. Postoperative breast satisfaction was also evaluated by the physicians.Results:With decision-making assistance, breast augmentation patients＇ satisfaction with breasts was (80.27±11.45) points, satisfaction with surgical results (83.41±12.29) points, social and psychological status scores (87.24±7.62) points, and sexual life status scores (85.49±7.90) points, physical condition score (73.94±8.98) points. There was no statistical difference in the scores of breast size between physicians and patients ( P>0.05). In the satisfaction score and total score of breast shape and feeling, physicians＇ scores were higher than patients＇ self-report scores, and the difference was statistically significant ( P<0.05). Conclusions:The patient self-reported postoperative outcomes are at a high level under the application of decision aid program. We can further improve the decision aid program for breast augmentation patients, adjust patient＇s surgical expectation, and realize shared decision making.

Abstract Background and objectives: PECS I block was first described for surgery involving the pectoralis muscles. No randomized clinical trial has been conducted on surgeries that directly involve these muscles, such as subpectoral breast augmentation. We hypothesized that PECS I block would decrease pain in the postoperative period in this population. Methods: This was a randomized, double-blind, placebo-controlled trial in women undergoing subpectoral breast augmentation surgery. PECS I block was performed using 0.4 mL.kg-1 of 0.9% saline on one side and bupivacaine (0.25%) on the other side, each patient being her own control. Numeric Rating Scale (NRS) pain scores (0 - 10) were measured at rest and during movement. The primary outcome was pain score at rest 30 minutes after arrival in the PACU. To detect a clinically significant difference of 50% in pain reduction, 14 volunteers were enrolled (power of 90% and alpha < 0.05). Results: In the PACU, three patients had no difference in pain between sides, five had reduced pain on the placebo side, and six had reduced pain on the bupivacaine side. In the bupivacaine group, pain scores at rest at 5, 30 and 60 minutes and 24 hours were 4.89 (4.23 - 5.56; mean 95% CI), 3.75 (3.13 - 4.37), 3.79 (2.93 - 4.64), and 2.29 (1.56 - 3.01), respectively, whereas in the placebo group, they were 4.96 (4.32 - 5.60), 4.00 (3.50 - 4.49), 3.93 (3.12 - 4.73), and 2.29 (1.56 - 3.01), respectively. Conclusions: PECS I block in patients undergoing breast augmentation surgery does not provide better pain relief than placebo. Therefore, the indications for PECS I block in breast augmentation surgery should be reconsidered.
Resumo Justificativa e objetivos: O bloqueio PECS I foi descrito pela primeira vez para cirurgia envolvendo os músculos peitorais. Nenhum estudo clínico randomizado foi realizado em procedimentos envolvendo diretamente os músculos peitorais, como a mamoplastia de aumento submuscular. Nossa hipótese foi de que o bloqueio PECS I diminuiria a dor pós-operatória nessa população. Método: Realizamos estudo randomizado, duplo-cego, controlado por placebo em mulheres submetidas à mamoplastia de aumento submuscular. Realizamos o bloqueio PECS I com 0,4 mL.kg-1 de solução salina a 0,9% de um lado e bupivacaína (0,25%) do outro lado, sendo cada paciente seu próprio controle. Os escores da Escala de Avaliação Numérica (EAN) de dor (0 - 10) foram obtidos em repouso e durante movimento. O desfecho primário foi o escore de dor em repouso 30 minutos após a chegada à SRPA. Para detectar uma diferença clinicamente significante de 50% na redução da dor, 14 voluntárias foram incluídas (poder de 90% e alfa < 0,05). Resultados: Na SRPA, três pacientes não apresentaram diferença na dor entre os lados, cinco relataram menos dor no lado do placebo e seis, menos dor no lado da bupivacaína. No grupo bupivacaína, os escores de dor em repouso aos 5, 30 e 60 minutos e 24 horas foram 4,89 (4,23 - 5,56; IC médio 95%), 3,75 (3,13 - 4,37), 3,79 (2,93 - 4,64) e 2,29 (1,56 - 3,01), respectivamente, enquanto no grupo placebo foram 4,96 (4,32 - 5,60), 4,00 (3,50 - 4,49), 3,93 (3,12 - 4,73) e 2,29 (1,56 - 3,01), respectivamente. Conclusões: O bloqueio PECS I em pacientes submetidas a mamoplastia de aumento não oferece melhor alívio da dor do que o placebo. Portanto, as indicações para bloqueio de PECS I na cirurgia de aumento de mama devem ser reconsideradas.

@#The relationship between the use of liquid silicone for breast augmentation and carcinogenesis remains undetermined due to limited data reported, especially regarding its risks for acquiring cancer. We documented a case of an 81-year-old woman who presented with bilateral enlarging breast masses with a known history of breast augmentation using liquid silicone. On microscopic examination, the malignancy showed both mesenchymal and epithelial components in a background of stromal changes related to liquid silicone. Based from morphology and immunohistochemistry studies (p63, CK, HMW-CK, and CK5/6, CD34, and BcL-2), this case was signed out as metaplastic carcinoma with mesenchymal differentiation. This rare case of metaplastic carcinoma with mesenchymal differentiation coexisting with liquid silicone, provides evidence supporting the link between cancer development and siliconomas.

Objective: To explore the risk factors related to periprosthetic infection after breast augmentation, and to provide a basis for reducing the risk of postoperative infection. Methods: A total of 1 056 female patients who underwent breast augmentation between January 2010 and January 2018 were analyzed retrospectively. The patients were 20 to 44 years old (mean, 31.6 years). The body mass index (BMI) was 19.0-31.1 kg/m 2, with an average of 24.47 kg/m 2. According to the periprosthetic infection standard of the United States Centers for Disease Control and Prevention (CDC), the patients were divided into infection group and non-infection group. Age, BMI, diabetes, previous history of immunosuppression, history of smoking, previous history of breast surgery, previous history of mastitis, combined with active dermatitis, surgical approach, the type and shape of breast prosthesis, implant in the different layers, combined with mastopexy, operation time, postoperative antibiotic time, postoperative breast crash, and postoperative potential infection surgery were analyzed by univariate analysis. The influencing factors of prosthetic infection were screened by logistic regression. Results: Periprosthetic infection occurred in 60 cases after operation, and the infection rate was 5.68%. Among them, 11 cases were acute infection, 33 cases were subacute infection, 16 cases were delayed infection, and 20 cases were positive in bacterial culture. Postoperative breast crash occurred in 114 cases. Univariate analysis showed that diabetes, previous history of immunosuppression, history of smoking, previous history of mastitis, postoperative breast crash, postoperative potential infection surgery, and combined with breast suspension were the influencing factors of postoperative periprosthetic infection ( P<0.05). Multivariate analysis showed that diabetes, history of smoking, and postoperative breast crash were the risk factors of periprosthetic infection ( P<0.05). Conclusion: Diabetes, smoking, and postoperative breast crash are the risk factors of periprosthetic infection after breast augmentation.
RÉSUMÉ
Background@#Autologous fat grafting has gained popularity in breast augmentation. Various methods can be used to estimate the volume retention rate. This systematic review aimed to establish whether the type of method used for measuring breast volume is a factor that influences the reported volume retention rate.@*Methods@#Studies were identified using the electronic databases PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science from inception of the database up to February 2019. Articles describing autologous fat grafting for breast augmentation were selected based on pre-determined inclusion and exclusion criteria. The characteristics of the included studies were summarized, and the reported volume retention rate from the studies was compared. A quality assessment of all included articles was performed using the methodological index for non-randomized studies criteria.@*Results@#A total of 618 articles were identified, of which 12 studies, with a total of 1337 cases, were eligible. The retention rate of injected adipose tissue varied when the method of fat grafting and volume analysis used were both the same, as well as when the method of fat grafting was the same but the method of volumetric evaluation used was different.@*Conclusions@#Currently, the tools available for estimating the volume retention rate come with limitations. In order to objectively evaluate the percentage of graft retention, a standard protocol that applies to the different methods should be established in the future.

Dentro de los factores determinantes, existió una relación positiva entre el volumen de la prótesis y la mejoría en la calidad de vida de forma global (p = 0,032) y en los dominios «autoimagen y autoestima¼ (p = 0,01) y «vida sexual¼ (p = 0,001). Conclusión: La cirugía de aumento mamario incrementa significativamente la calidad de vida medido mediante el instrumento Breast-Q®. Los determinantes de la mejoría en la calidad de vida estarían directamente relacionados con el volumen de la prótesis.
Introduction: Breast-Q® instrument has been used for measuring the quality of life of patients undergoing breast augmentation surgery. The factors that determine the improvement in the quality of life of these patients are unknown. The aim of this work is to identify the determinant factors of improvement in the quality of life in patients undergoing breast augmentation. Materials and methods: A prospective cohort of 52 patients undergoing breast augmentation was studied. Sociodemographic features, anthropometric measurements, variables related to surgery were studied and the Breast-Q® instrument was applied. For statistical analysis it was used descriptive statistics and linear and logistic regression models. Results: We found improvement in the quality of life, globally (P < .00001) and in all domains except "physical symptoms’ domain. Among the determining factors, there was a positive correlation between the prosthesis volume and improvement in quality of life globally (P = .032) and in the domains "self-image and self-esteem" (P = .01) and "sexual life" (P = .001). Conclusion: Breast augmentation surgery significantly increases the quality of life measured by the Breast-Q® instrument. The determinant factors of improvement in quality of life, would be directly related to the implants volume.

Objective To explore the advantage of Body-Jet hydrodynamic liposuction system in autologous fat transplantation.Methods Through the unique hydrodynamic jet washing liposuction technology and the closed fat storage system,the fat was filtrated and purified,and then the fat was injected into the posterior space of greater pectoral muscle and breast tissue as well as subcutanous tissue of the breast with unique reverse-directed double orifice injector.During May 2015 to July 2016,27 patients were treated in our hospital and followed up for 30 to 180 days.Results All patients had good incision healing;there were no rugged skin,hematoma,seroma and other complications in the liposuction site.In 25 patients after augmentation the breast had rounded appearance and good feeling;1 patient presented liquefied fat,1 patient had poor survival of the injected fat;later 2 cases underwent second surgery.Conclusions The liposuction system can be applied in autologous adipose transplantation breast augmentation.The procedure is simple and quick.The survival rate after adipose transplantation is high with quick recovery.The shape of the breast is full and round with good feeling.
