BACKGROUND
Breast augmentation through the injection of polyacrylamide hydrogel (PAAG) was a popular procedure in the past, but it has since been prohibited due to various complications, including masses, migration, infection, inflammation, and even cancer. However, there were rare cases of granulomatous mastitis with pectoralis major muscle defect following PAAG injection for breast augmentation.
CASE DESCRIPTION
A 40-year-old female patient presented with a swollen and suppurative mass in her left breast and was insensitive to antibiotics. She was admitted to our department for further treatment after 7 months with progressive local and general symptoms. Ultrasound imaging showed ill-defined heterogeneous echoes, and contrast-enhanced magnetic resonance imaging (MRI) revealed non-mass enhancement lesions in the multiregional distribution in Breast Imaging-Reporting and Data System 4A (BI-RADS 4A) with oedema in the retroglandular space and multiple enlarged lymph nodes in the ipsilateral axilla. Intraoperative observations revealed necrotic tissues, multiple abscesses, residual mucoid PAAG prosthesis diffused into the mammary glands and intramuscularly into the pectoralis muscle, and partial loss of pectoralis major muscle. Histopathological results revealed foreign-body granulomas accompanied by gel-like granular PAAG and proliferative inflammatory cells. She recovered after undergoing the characteristic surgical management in our center under general anesthesia and had no recurrence during the 2-year follow-up.
CONCLUSIONS
This case revealed that PAAG injection for augmentation mammaplasty, even after the removal operation, could result in subsequent complications, including granulomatous mastitis and pectoralis major muscle damage. PAAG filler complications are difficult to treat, therefore, it is essential to establish appropriate and effective therapeutic procedures.

Breast cancer ranks among the most commonly diagnosed cancers worldwide and bears the highest mortality rate. As an integral component of cancer treatment, mastectomy entails the complete removal of the affected breast. Typically, breast reconstruction, involving the use of silicone implants (augmentation mammaplasty), is employed to address the aftermath of mastectomy. To mitigate postoperative risks associated with mammaplasty, such as capsular contracture or bacterial infections, the functionalization of breast implants with coatings of cyclodextrin polymers as drug delivery systems represents an excellent alternative. In this context, our work focuses on the application of a mathematical model for simulating drug release from breast implants coated with cyclodextrin polymers. The proposed model considers a unidirectional diffusion process following Fick's second law, which was solved using the orthogonal collocation method, a numerical technique employed to approximate solutions for ordinary and partial differential equations. We conducted simulations to obtain release profiles for three therapeutic molecules: pirfenidone, used for preventing capsular contracture; rose Bengal, an anticancer agent; and the antimicrobial peptide KR-12. Furthermore, we calculated the diffusion profiles of these drugs through the cyclodextrin polymers, determining parameters related to diffusivity, solute solid-liquid partition coefficients, and the Sherwood number. Finally, integrating these parameters in COMSOL multiphysics simulations, the unidirectional diffusion mathematical model was validated.

BACKGROUND
Breast augmentation is one of the most commonly performed aesthetic surgery procedures. Yet, few reports in the literature analyze individual surgeon experiences with a unified surgical method on a large group of patients. This study aimed to analyze a single surgeon's complications rate and experience with the Akademikliniken augmentation mammaplasty method from the beginning of his career.
METHODS
A retrospective outcome analysis of all patients (n = 1646) who underwent breast augmentation between 2009 and 2021 performed by a single surgeon was conducted. Complications and reoperation rates were evaluated. In addition, correlations with the patient and implant characteristics and insertion-method-related risk factors were analyzed.
RESULTS
In total, 1212 female patients (mean age, 31.47 years) were analyzed. The minimal follow-up for every patient was 6 months (mean follow-up, 18.35 months). The total complication rate was 7.1%, and the most common complication (2.64%) was capsular contracture (Baker scale III/IV). Implant insertion with a funnel significantly lowered the overall risk of complications ( = 0.009). Statistical analysis indicates that the single independent risk factors for primary breast augmentation are patient age younger than 27 years, initial breast size B and C, and tobacco smoking.
CONCLUSIONS
This study indicated that capsular contracture and implant rotation are the most common complications of analyzed primary augmentation mammoplasty. It also identifies various risk and protection factors, such as funnel usage, which should be considered by the surgeon when performing this type of procedure.

INTRODUCTION
In recent years, artificial intelligence (AI) has gained popularity, even in the field of plastic surgery. It is increasingly common for patients to use the internet to gather information about plastic surgery, and AI-based chatbots, such as ChatGPT, could be employed to answer patients' questions.The aim of this study was to evaluate the quality of medical information provided by ChatGPT regarding three of the most common procedures in breast plastic surgery: breast reconstruction, breast reduction, and augmentation mammaplasty.
METHODS
The quality of information was evaluated through the expanded EQIP scale. Responses were collected from a pool made by ten resident doctors in plastic surgery and then processed by SPSS software ver. 28.0.
RESULTS
The analysis of the contents provided by ChatGPT revealed sufficient quality of information across all selected topics, with a high bias in terms of distribution of the score between the different items. There was a critical lack in the "Information data field" (0/6 score in all the 3 investigations) but a very high overall evaluation concerning the "Structure data" (>7/11 in all the 3 investigations).
CONCLUSION
Currently, AI serves as a valuable tool for patients; however, engineers and developers must address certain critical issues. It is possible that models like ChatGPT will play an important role in improving patient's consciousness about medical procedures and surgical interventions in the future, but their role must be considered ancillary to that of surgeons.

Review
BACKGROUND
Vulvar migration is a rare complication of filler injection for breast augmentation, generally presenting as repeated pain and fever. We will report a case of woman with polyacrylamide hydrogel breast injection develops vulvar abscess.
CASE PRESENTATION
A woman with a history of polyacrylamide hydrogel breast injection was noted to have vulvar abscess due to migration of filler materials. Filler removal surgery and vacuum sealing drainage was performed for this patient. The patient was discharged from the hospital with no further complications. After a review of pertinent literature, only four previous case reports are found. Local inflammatory response, infection, large volume injections, inframammary fold destruction, hematogenous or lymphatic migrate, trauma, gravity and external pressure could play essential parts in the migration of injected filler.
CONCLUSION
Polyacrylamide hydrogel migration poses a worldwide challenge, necessitating personalized solutions. Our case study underscores the importance of comprehensive examinations for individuals with a history of filler breast injection when suspecting vulvar filler migration.

In the late nineties, polyacrylamide gel (PAAG) gained popularity in China as a soft tissue filler for breast augmentation and contouring, but was banned 10 years later due to the increasing incidence of complications. We report a case of PAAG complication that occurred 20 years after the initial injection, where the patient had significant unilateral breast swelling and an intracapsular lesion. Surgical removal of the breast filler and immediate breast reconstruction was successfully performed, and histology confirmed a benign breast lesion. These findings highlight the importance of clinical awareness of PAAG breast filler complications.

BACKGROUND
The fat-augmented latissimus dorsi (FALD) flap is an evolution of the traditional latissimus dorsi (LD) flap, which allows to obtain a total autologous breast reconstruction (BR) avoiding the use of breast implants. The aim of this study was to develop a predictive preoperative formula in order to estimate and optimize the amount of fat to be transferred during FALD flap BR, using only anthropometric measurements.
METHODS
We conducted a prospective clinical study between September 2020 and April 2023. All patients underwent back pre-operative ultrasound scan to assess the subcutaneous skin paddle thickness (SPT) and a regression analysis was performed to evaluate which anthropometric variable had a better correlation with this thickness.
RESULTS
Data from 66 FALD flaps were collected. The mean SPT was 11.95 mm (SD 4.56). A significant correlation between SPT and body mass index (BMI) was found (r = 0.640, p < 0.0001). Using the fat-to-capacity ratio (113%), the following formula (the FALD-V) was developed to predict the needed fat transfer into FALD flap: [-509 + 12.32 × BMI + 11.71 × skin paddle width + 17.43 × skin paddle height] × 1.13. The considered variables (BMI, skin paddle width and skin paddle height) were statistically significant (p < 0.001, p = 0.0483, p = 0.0154, respectively). The cross-validation confirmed the accuracy of the formula (r = 0.810).
CONCLUSION
The FALD-V can be used as an innovative complimentary device in the planning of FALD flap one-stage total autologous BR. To enhance its application, a 3.0 WebApp at www.braflap.com (and www.breast-v.com) is available free of charge for both iOS and Android devices.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has been regarded as a long-term problem after silicone breast implantations. We report a case in which BIA-ALCL and breast cancer were not detected preoperatively, with subsequent removal of a ruptured breast implant. A 52-year-old woman had silicone breast implants on both sides for breast augmentation 15 years ago. Right axillary lymphadenopathy and intracapsular ruptures were noted by magnetic resonance imaging. Right axillary lymph node biopsy was performed at our department of breast surgery. Flow cytometry for BIA-ALCL was also performed using the exudate around the implant. The results were negative for breast cancer and BIA-ALCL. However, taking into consideration exacerbation of breast implant rupture and the patient's anxiety about BIA-ALCL, ruptured bilateral implants were removed by total capsulectomy. The postoperative course was uneventful 1 year after the operation, and her anxiety was dispelled despite her breast deformity. Appropriate explantation and periodic examination may be required to prevent excessive anxiety.

BACKGROUND
Evaluation of practice patterns by American Board of Plastic Surgery (ABPS) diplomates allows for a greater understanding as to how the field is progressing. Understanding evolving procedural trends can give insight into plastic surgeons' subspecialty focus and influence resident training to prepare them for future practice.
METHODS
American Society of Plastic Surgeons member only projections for aesthetic and reconstructive procedures were reviewed from 1999 to 2018 in 5-year increments to identify shifts in frequency between the beginning (1999-2003) and end (2014-2018) of the timeframe. Tracer utilization for all four ABPS modules were also examined between 2014 and 2018. Descriptive statistics were performed to identify significant changes ( < 0.05) in subspecialty focus and procedure trends.
RESULTS
Annual procedure incidence between 2014 and 2018 was compared with that between 1999 and 2003. The annual number of procedures more than doubled from 3,244,084 to 6,628,082. Among reconstructive procedures, there was a statistically significant increase in the number of breast reconstruction, breast implant removal, and maxillofacial surgery procedures, and a statistically significant decrease in the number of procedures focused on reconstruction of birth defects, burn injuries, and hand anomalies. In aesthetic surgery, significant increases were seen in the number of augmentation mammoplasty, abdominoplasty, and mastopexy procedures, with significant decreases in the number of blepharoplasty and rhinoplasty procedures.
CONCLUSIONS
Understanding the changing practice patterns of ABPS diplomates is essential to define the direction that our specialty is taking over time, and to guide program directors in plastic surgery on areas of focus for appropriate training of plastic surgeons.

In this report, we present a case study of a rare human bacterium, , which caused an infection in a patient who had undergone autologous fat-based breast augmentation using cryopreserved fat. This infection occurred during a secondary fat grafting procedure. To identify the bacteria causing the infection, we used high-throughput DNA sequencing technology since this bacterium is seldomly reported in human infections. The patient was successfully treated with intravenous imipenem. We also discuss potential factors that may have contributed to this unusual bacterial infection and propose that DNA sequencing can be a useful tool in cases where standard culture techniques fail to identify the causative agent. Additionally, we highlight the importance of further research on the cryopreservation of fat. In summary, this case highlights the possibility of rare bacterial infections occurring after fat grafting procedures and emphasizes the importance of identifying the causative agent through advanced techniques such as DNA sequencing. Further research is needed to improve our understanding of the risks associated with cryopreservation of fat and to identify ways to prevent these types of infections in the future.
