Breast Splint for Prevention of Nipple-areolar Complex Malposition after Direct-to-implant Breast Reconstruction.

ABSTRACT: Breast reconstruction with immediate placement of breast implants (direct-to-implant methods) following nipple-sparing mastectomy has increased because of the low burden on the patient and good aesthetic results. However, nipple-areolar complex (NAC) malposition after this surgery remains a common complication that has yet to be entirely resolved. Here, we introduce an approach using Duoactive CGF to prevent postoperative NAC malposition. Immediate postoperative fixation of Duoactive CGF cranially to the NAC of the operated breast was applied for 2-4 weeks. This is referred to as a breast splint. In the study, nine patients who received breast splints and 15 patients who did not were enrolled. The NAC position on the splint-treated breast was compared with that on the healthy side within 6 months after surgery. A case with little visual malposition was defined as having a good outcome, based on the deviation in the cranial direction not exceeding the position of the contralateral NAC. Our preliminary data demonstrated that the rate of good outcomes was significantly higher (P = 0.028) in cases in which a breast splint was used, compared with those that were not treated with a breast splint (7/9, 78.8% versus 4/15, 26.7%). Postoperative application of a breast splint using Duoactive CGF is a simple and useful method to prevent NAC malposition after breast reconstruction, using a direct-to-implant method.

Project description:BackgroundAlthough video-assisted breast surgery is gaining popularity, endoscopic reconstruction after mastectomy is still facing lots of problems, bring about that endoscopic method has not yet become a standard procedure for breast cancer reconstruction. Here, we introduce a novel surgical technique of video-assisted transaxillary nipple-sparing mastectomy and immediate implant-based breast reconstruction and describe the detailed surgical procedure using this technique.MethodsDetailed steps of surgical procedure, the patient characteristics and the mean operative time of this new technique were described in this article. All patients were asked to score their satisfaction with their reconstructed breasts preoperatively, 1 month, 3 months, 6 months and 12 months postoperatively using the BREAST-Q.ResultsAt first, we used our "conventional method" and performed on 10 patients from April 2017 to June 2020; the operative time was 324.80 ± 66.39 minutes. After improving several procedures of the technique, the "optimized method" was performed on 14 cases from July 2020 to November 2020; the operative time decreased to 193.71 ± 28.75 minutes with shortest was 133 minutes; the optimized method was novel and easy to learn and be generalized. Most of the patients were satisfied with the reconstruction results. There was no significant difference between preoperative scores and scores at 3 months, 6 months and 12 months (p = 0.364). Since there is no wound on the breast dome, no obvious postoperative complications were observed except for one patient presented with infection.ConclusionsThis new technique has allowed surgeons to achieve excellent and reproducible outcomes in a single-stage procedure and represents an excellent technique for patients who wish to have a scarless and aesthetically pleasing appearance after mastectomy for breast cancer. This article also highlights the mean operative time (193.71 ± 28.75 minutes) that has been made possible with this new technique.Level of evidence vThis journal requires that authors assign a level of evidence to each article.

Project description:There are more than 3 million breast cancer survivors living in the United States of which a significant number have undergone mastectomy followed by breast and nipple-areolar complex (NAC) reconstruction. Current strategies for NAC reconstruction are dependent on nonliving or nonpermanent techniques, including tattooing, nipple prosthetics, or surgical nipple-like structures. Described herein is a tissue engineering approach demonstrating the feasibility of an allogeneic acellular graft for nipple reconstruction. Nonhuman primate (NHP)-derived NAC tissues were decellularized and their extracellular matrix components analyzed by both proteomic and histological analyses. Decellularized NHP nipple tissue showed the removal of intact cells and greatly diminished profiles for intracellular proteins, as compared with intact NHP nipple tissue. We further evaluated the biocompatibility of decellularized grafts and their potential to support host-mediated neovascularization against commercially available acellular dermal grafts by performing in vivo studies in a murine model. A follow-up NHP pilot study evaluated the host-mediated neovascularization and re-epithelialization of onlay engrafted decellularized NAC grafts. The murine model revealed greater neovascularization in the decellularized NAC than in the commercially available control grafts, with no observed biocompatibility issues. The in vivo NHP model confirmed that the decellularized NAC grafts encourage neovascularization as well as re-epithelialization. These results support the concept that a biologically derived acellular nipple graft is a feasible approach for nipple reconstruction, supporting neovascularization in the absence of adverse systemic responses. Impact statement Currently, women in the United States most often undergo a mastectomy, followed by reconstruction, after being diagnosed with breast cancer. These breast cancer survivors are often left with nipple-areolar complex (NAC) reconstructions that are subsatisfactory, nonliving, and/or nonpermanent. Utilizing an acellular biologically derived whole NAC graft would allow these patients a living and permanent tissue engineering solution to nipple reconstruction.
