Background: Direct-to-implant prepectoral breast reconstruction in the last years demonstrated to be a feasible and advantageous method in selected cases because it respects chest wall musculature integrity and avoids animation deformity. Current approaches involve implant wrapping with Acellular Dermal Matrix (ADM) or synthetic mesh to guarantee implant coverage and stability and reduce complications. Prepectoral polyurethane implant positioning without further coverage is an alternative breast reconstruction method poor described in literature.
Patient And Methods: A single-institution retrospective analysis was performed on 453 patients, extending our previous preliminary experience, who underwent nipple-sparing mastectomy (NSM) and prepectoral polyurethane implant positioning between December 2017 and June 2021. Follow-up included postoperative complications record and self-reported patient's satisfaction.
Results: A total of 784 mastectomies were performed in 453 patients. 331 were bilateral procedures (73.1%) and 122 were unilateral (26.9%). Minimum follow-up time was 6 months and maximum was 42 months. No major complications were reported. Contour defects and excessive implant visibility occurred in 82 patients (18.1%) and was successfully managed with autologous fat grafting.
Conclusion: Nipple-sparing mastectomy with immediate prepectoral polyurethane implant reconstruction without the need for ADM or mesh is a feasible and safe option. Accurate patient selection and respectful mastectomy technique is crucial to achieve optimal outcomes with this approach. Fat grafting is a useful refinement procedure to improve cosmetic results in this setting.

Background: Breast augmentation and breast reconstruction with implants are among the most performed surgery worldwide.
Objective: In the search for an ideal implant in terms of safety, shape and consistency, the authors report their experience with a subtype of breast implant, the Diagon\Gel 4Two implants, in both cosmetic and reconstructive cases by analyzing their experience on 116 consecutive patients.
Methods: One hundred and sixteen consecutive patients undergoing both aesthetic and reconstructive breast surgery using Diagon\Gel 4Two Implants between January 2021 and December 2022 were retrospectively reviewed.

Breast cancer treatment increasingly incorporates immediate prepectoral prosthetic reconstruction after conservative mastectomy, including nipple-sparing (NSMs) and skin-sparing mastectomies (SSMs). Although recent data from the literature show that postmastectomy radiotherapy (PMRT) after prepectoral reconstruction presents good clinical results, with reduction in capsular contracture and implant migration, compared to the traditional submuscular technique, these patients have higher rates of long-term complications when compared with nonradiated patients. This study evaluates the protective effects of autologous fat grafting to reduce long-term radiotherapy-induced complications in breast cancer patients submitted for prepectoral reconstruction with polyurethane-covered (PU) implants.
View Article and Find Full Text PDFBackground: Revisional surgery for aesthetic breast augmentation remains a challenging procedure. Polyurethane (PU) implants have been found to avoid capsular contracture recurrence as well as to prevent implant displacement by bio-integrating with the pocket.
Objectives: Our study aimed to assess the use of PU implants in breast revisional surgery and to provide an algorithm.

Background: Interfaces continue to be used in prepectoral breast reconstruction to refine breast appearance, but more clinical data are required to assess their effectiveness. This study compares the rates of capsular contracture, breast esthetics, and patient satisfaction between two commonly used interface materials, acellular dermal matrix (ADM) and polyurethane (PU) foam.
Methods: A cross-sectional assessment was conducted on all patients who underwent prepectoral direct-to-implant reconstruction with an interface material between June 2018 and June 2022.
Local Flaps to Cover Skin Necrosis after Skin-sparing Mastectomy and Prepectoral Reconstruction from PreQ-20 Trial.

Article Synopsis
- - Recent shifts in mastectomy practices have led to higher indications for the procedure, especially in women who are at higher risk for breast cancer, with prepectoral reconstruction using polyurethane implants as a viable option
- - A study assessed 226 women undergoing skin-sparing mastectomies, revealing a 20.9% complication rate primarily due to wound dehiscence, with 13 local flaps successfully performed to cover exposed implants
- - The findings suggest that local flaps are a low-risk option to prevent implant loss from skin complications, although 46.2% of cases still experienced implant cover failure
