    Thermal Injury to Reconstructed Breasts from Commonly Used Warming Devices: A Risk for Reconstructive Failure
    (Wolters Kluwer Health, 2016) Faulkner, Heather; Colwell, Amy; Liao, Eric; Winograd, Jonathan; Austen, William
    Background: Sensation is decreased or absent after breast reconstruction. This leaves reconstructed breasts vulnerable to injury from common household thermal sources such as heating pads and hot water bottles. We sought to categorize these injuries, provide a treatment plan, and prevent these injuries in the future. Methods: A retrospective review of patients who had sustained burns to reconstructed breasts with household devices was performed at a single institution. A PubMed search was performed to identify and summarize articles cataloguing patients who had suffered burns to breast reconstructions. Results: Five patients in our practice were affected. Fifteen articles were identified in the literature search. A total of 40 patients had sustained thermal injury to reconstructed breasts, with the majority being full thickness burns (67.5%). Patients who sustained full thickness burns to reconstructed breasts were more likely to require an operative procedure compared with patients who sustained partial thickness burns (P = 0.0076). Conclusions: Reconstructed breasts are at risk for injury from commonly used household warming devices and ambient heat from the sun. As a result, patients should be counseled about these risks accordingly, to avoid injury or loss of reconstruction. These injuries require immediate vigilant treatment.

    Tissue Reinforcement in Implant-based Breast Reconstruction
    (Wolters Kluwer Health, 2014) Scheflan, Michael; Colwell, Amy
    Background: Tissue reinforcement with allogeneic or xenogeneic acellular dermal matrices (ADMs) is increasingly used in single-stage (direct-to-implant) and 2-stage implant-based breast reconstruction following mastectomy. ADMs allow surgeons to control implant position and obviate the need for submuscular implant placement. Here, we review the benefits and risks of using ADMs in implant-based breast reconstruction based on available data. Methods: A comprehensive analysis of the literature with focus on recent publications was performed. Additional information regarding the proper use of ADMs was based on our institutional experience. Results: ADM use may improve definition of the lateral confines of the breast and lower pole projection. It may facilitate direct-to-implant procedures and improve aesthetic outcomes. The effect of ADMs on complication rates remains controversial. Known patient risk factors such as obesity, smoking, and radiotherapy should be considered during patient selection. For patients with healthy, well-vascularized skin envelopes, ADM-assisted direct-to- implant reconstruction is a safe and cost-effective alternative to 2-stage implant reconstruction, with low complication rates. ADMs may be used to treat capsular contracture, and limited available data further suggest the possibility that ADMs may reduce the risk of capsular contracture. Novel synthetic or biosynthetic tissue reinforcement devices with different physical and ease-of-use properties than ADMs are emerging options for reconstructive surgeons and patients who seek to avoid tissue products from human or mammalian cadavers. Conclusions: ADM-assisted implant-based breast reconstruction may improve aesthetic outcomes. However, appropriate patient selection, surgical technique, and postoperative management are critical for its success, including minimizing the risk of complications.

    Optimizing Nipple Position following Nipple-Sparing Mastectomy
    (Wolters Kluwer Health, 2017) Colwell, Amy; Taylor, Erin; Specht, Michelle; Orringer, Jay S.
    Background: The best treatment for nipple malposition following nipple-sparing mastectomy is prevention. This article reviews basic elements for success in nipple-sparing mastectomy and offers an option to patients with grade 2–3 breast ptosis who strongly desire to preserve the nipple. Methods: Retrospective review identified patients undergoing nipple-sparing mastectomy and immediate reconstruction. Results: Patient selection centered on realistic goals for postoperative breast size, nipple position, and when not to save the nipple. The choice of device considered projection and nipple centralization as equal components and led to wider, lower profile devices selectively for the first stage of reconstruction. In severe grade 2–3 nipple ptosis, an inferior vertical incision or wedge excision was used to enhance nipple position postoperatively. Eighteen consecutive patients underwent 32 implant-based breast reconstructions following nipple-sparing mastectomy with the vertical incision. The average age was 45 years old, and the average body mass index was 26.7. Direct-to-implant reconstruction was performed in 25%, whereas 75% had tissue expander-implant reconstruction. Overall complications included infection (3%) and nipple necrosis (3%) leading to explant in 1 reconstruction. Conclusions: The final nipple position following nipple-sparing mastectomy can be optimized with preoperative planning. The vertical incision, combined with proper patient selection and choice of device, may increase eligibility for nipple-sparing procedures in patients with grade 2–3 ptosis who desire nipple preservation.
