BACKGROUND: Implant-based breast reconstruction is the most prevalent form of breast reconstruction. Autologous fat grafting (AFG) was conceptualized as an alternative to implant-based breast reconstruction and was found to be a reliable reconstruction modality. However, usually, a few grafting rounds are required to create the desired shape and size of the breast. Current literature describes ample experience with AFG as an adjunct to implant-based breast reconstruction for improving appearance. However, the utilization of breast implants following initial AFG has been sparingly described. The primary advantage of this study is the creation of new fat tissue as a breast mound. The reconstruction is then concluded by inserting an implant into this new mound. This approach reduces the overall number of fat injections needed to achieve the desired outcome, as well as the total volume of the implant.
METHODS: This IRB-approved retrospective study was conducted between January 2015 and December 2021. All women who underwent delayed breast reconstruction with AFG during this timeframe and wanted to complete it with a silicone implant as a last stage were included in the study.
RESULTS: A total of 29 patients (33 breasts) underwent delayed breast reconstruction with AFG and a silicone implant as the final stage. In all cases, the results were satisfying without any major complications. Minor complications were observed with one patient and included an infection.
CONCLUSIONS: The findings of this study have demonstrated the effectiveness of this procedure together with patient satisfaction, thus highlighting the potential advantages that this approach offers.

BACKGROUND: The Brazilian Butt Lift (BBL) is a safe technique that entails body reshaping through buttock augmentation using autologous fat transfer.
METHODS: Between 2018 and 2022, 3000 patients underwent surgery. Each procedure commenced with the patient in supine position, starting with abdominal liposuction, followed by fat transfer to hips. Subsequently, the patient was repositioned to a prone stance. Liposuction of the back and waist ensued, concluding the surgery with fat transfer to the buttocks. Stringent precautions were implemented to ensure the safety of the patient throughout the procedure.
RESULTS: Eighty-six percent of patients express satisfaction with their outcomes, while seventy percent of the transferred fat calls survive in the buttocks. One serious complication and some minor complications have been encountered and effectively managed through conservative measures.
CONCLUSIONS: BBL proves to be a safe and satisfactory surgery when performed by experienced surgeons who adhere to fundamental principles.

Fat transfer is increasingly used as part of our reconstructive armamentarium to address the challenges encountered in burn wounds and reconstructive surgery. The present systematic review aimed to evaluate the effectiveness of autologous fat transfer for acute burn wound management. A systematic review of the US National Library of Medicine, Cochrane Library, Web of Science, and Embase was conducted on October 15, 2022 (registration number CDR42022369726). A database watch was performed until submission of the manuscript. The review focused on wound healing. All studies reporting fat transfer in adult patients (at least 5 patients reported) with deep 2nd degree burn wounds were included. The database search yielded a total of 720 records and 367 patients were included from 3 studies. A statistically significant improvement in scar texture, scar appearance, and time to healing was reported in one study in the fat transfer group versus control (P<0.001). Similarly, scores for scar color, scar thickness, scar stiffness, and scar regularity increased significantly. The small number of included studies and their heterogeneity did not allow a meta-regression to be performed. This systematic review emphasizes the limited evidence currently available regarding the use of autologous fat transfer to improve burn wound healing in adult patients, even though it seems promising. Future search should focus on randomized controlled trials with a larger number of participants.

Gluteal augmentation has become a popular esthetic procedure since its inception. The main methods are augmentation using implants or autologous fat grafting, which is the harvesting and grafting of patients\' own fat tissue. The last review comparing the safety of these methods was written 7 years ago, which warrants the writing of a new one. PubMed, Cochrane, and Medline were searched for studies focusing on the methods of gluteal augmentation listed previously. Five search terms were used and 15 studies fulfilled the criteria. The data were cataloged according to the method described and outcomes compared. Seven articles focused on gluteal implants and another seven assessed autologous fat grafting, whereas one detailed both. The most common complications in 524 implant procedures were wound dehiscence (9.16%), excessive implant palpability (5.92%), and seroma (3.82%), with an overall complication rate of 25%. The most common complications in 1788 gluteal fat augmentation procedures were seroma (6.9%), infection (3.0%), and transient sciatic paresthesia (1.0%), with an overall complication rate of 13%. Several articles listed satisfaction figures, but these were not assessed because this article was not powered to assess this outcome. Overall, gluteal augmentation using autologous fat grafting leads to fewer postoperative complications than implants and allows greater contouring of the buttocks and the surrounding areas. However, it can also be a far more dangerous procedure if certain recommendations are not followed.

A 52-year-old female patient developed facial fat necrosis presenting with cutaneous induration three weeks after minimal access cranial suspension (MACS) lift with autologous fat grafting from the abdomen. Given that the patient received the Moderna SARS-CoV-2 vaccine one week after surgery, we hypothesize that the former predisposed her to tissue ischemia leading to fat necrosis. Histological findings after biopsy were consistent with fat necrosis, which included marked dermal fibrosis with areas of focal fat necrosis, lipophages, multinucleated giant cells, and siderophages. It is our hope that documenting this rare development in literature may serve as encouragement for adverse effect reporting after the SARS-CoV-2 vaccine administration and may boost inspection and monitoring of other health consequences by regulating agencies.

We present a 23-year-old male patient with severe PS, characterized by marked left thoracic wall deformity. Reconstruction was performed using the Fat-Augmented Latissimus Dorsi flap, which was fixed to the chest wall hollowing corresponding to where the pectoralis major muscle was missing. Patient was satisfied with final aesthetic and functional result.

Lupus panniculitis (LP) often presents with tender nodules and intermittent ulcers that then heal with scarring and lipoatrophy. The current mainstay of treatment is medical treatment. Research regarding the treatment of lipoatrophy from LP with autologous fat grafting is limited. We would like to share our experience in this rare case, which was treated with autologous fat transfer. A 48-year-old female presented with erythematous plaque, tender nodules, and ulcers following by a depression of the lesion at the left temporal area. The patient also had indurated erythematous plaque at her left cheek. Both lesions were aggravated by sunlight exposure. After several investigations, she was diagnosed as LP with secondary lipoatrophy and tumid lupus erythematosus at her left temporal and left cheek, respectively. She received antimalarial drug and topical steroids. The patient underwent two sessions of autologous fat transfer. She was satisfied with the volume and contour improvement in the scar following the injection of 8 and 3.7 mL of fat. Furthermore, the patient reported the remission of tender nodules and ulcers since the first fat graft injection. In conclusion, the autologous fat transfer is a simple and effective treatment for lipoatrophy and scar secondary to LP with promising results.

UNASSIGNED: Autologous fat transfer is common in breast augmentationor reconstruction. However, AFG recipient site in the breast for fat grafting has not been carefully investigated.
UNASSIGNED: Forty female patients requiring breast augmentation with fat grafting were randomly assigned into two groups. The retromammary group received 2/3 fat into the retromammary space and the other 1/3 into the subcutaneous and retropectoral planes. The retropectoral group received 2/3 fat into the retropectoral plane and the other 1/3 into the subcutaneous and retromammary planes. The fat grafting result at 6 months was assessed by 3D laser surface scanning and then ultrasound. Any complications were recorded during follow-up. Samples from a patient who underwent fat grafting for 6 months was obtained and histological examination was conducted.
UNASSIGNED: No significant difference in the retention rate after 6 months was observed between the two groups (retromammary group: 35.9% ± 6.6; retropectoral group: 39.3% ± 5.1, p = 0.1076). The retromammary grouphad a higher incidence of oil cyst formation than the retropectoral group. Histological examination showed that there were more oil cysts and mac2 positive macrophage infiltration in the fat cells in retromammary group, while retropectoral group had more small-size adipocytes.
UNASSIGNED: Although fat grafting into the retropectoral plane did not provide a superior fat graft retention rate, it did lower the incidence of complications. The retropectoral space show great potential to become a favorable recipient site.

A 59-year-old woman with prior bilateral lower eyelid autologous fat transfer, subdermal micro-needling and fractional radiofrequency skin resurfacing presented with delayed left-sided preseptal cellulitis with small multinodular abscesses unresponsive to oral outpatient antibiotic regimens and inpatient intravenous antibiotics. Wound culture revealed Mycobacterium chelonae infection treated successfully with a 4-month regimen of clarithromycin and tedizolid without recurrence. This case highlights (1) the need for vigilance and a broad differential in delayed post-operative wound infections including non-tuberculous mycobacterial infections, (2) resolution of infection without recurrence on clarithromycin and novel tedizolid oral antibiotic therapy, and (3) that caution should be exercised when performing combination autologous fat transfers with subdermal micro-needling procedures as the breakdown in skin integrity may potentiate infection.
