Staged Mastopexy Before Nipple-Sparing Mastectomy: Improving Safety and Appearance in Implant-Based and Autologous Breast Reconstruction.

BACKGROUND: Breast reconstruction following nipple sparing mastectomy in patients with large or ptotic breasts remains challenging because of the risk of ischemic complications and the difficulty in managing the redundant skin envelope. Staged mastopexy or breast reduction before the mastectomy/reconstruction has been shown to decrease the risk of complications and improve clinical outcomes. METHODS: A retrospective analysis was conducted of patients with a genetic predisposition to breast cancer who underwent staged breast reduction/mastopexy before nipple sparing mastectomy and reconstruction in our institution. In patients with in situ disease or invasive cancer, the first stage consisted of lumpectomy and oncoplastic reduction/mastopexy. Breast reconstruction at the second stage was performed with free abdominal flaps or breast implants and acellular dermal matrix. Data regarding the ischemic complications were recorded. RESULTS: In total, 47 patients (84 breasts) underwent this staged approach. All patients had a genetic predisposition to breast cancer. The time interval between the two stages was 11.5 months (range, 1.3 to 23.6 months). Twelve breasts (14.3 percent) were reconstructed with free abdominal flaps, 6 (7.1 percent) with tissue expanders and 66 (78.6 percent) with permanent subpectoral implants and acellular dermal matrix. There was one postoperative superficial nipple areolar complex epidermolysis (1.2 percent), and two partial mastectomy skin flap necrosis (2.4 percent). The mean follow-up time after completion of reconstruction was 8.3 months. CONCLUSION: Mastopexy or breast reduction before nipple sparing mastectomy and reconstruction is a safe procedure with a low risk of ischemic complications.

Analysis of Allergan's Biocell Implant Recall in a Major University Breast Center.

BACKGROUND: In May 2019, Health Canada released a national recall of all macrotextured breast implants that later became international in July 2019 regarding increasing accounts of suspected breast implant-associated anaplastic large cell lymphoma. In Canada, this recall targeted Allergan's Biocell implants. This report presents the postmortem of this comprehensive single-center recall, which had to be undertaken in a limited time. METHODS: Four months after the beginning of the recall, the authors analyzed the transcript of meetings to characterize the team assembled during the recall. Then, to reconstruct the systemic work plan as well as the crucial steps and actors of the recall process, a chronologic table of the 5 meetings held during the recall, agendas and transcripts of every meeting, electronic correspondences, and other documents created during the recall were consulted. RESULTS: Between 1996 and 2018, 1260 women were affected by the recall, meaning that they received Allergan's macrotextured implants. Ninety-two patients underwent explantation of the device or will undergo implant explantation. To this day, no patient was diagnosed with breast implant-associated anaplastic large cell lymphoma. CONCLUSIONS: Our center's experience highlights the utmost importance of building a national breast implants registry. We recommend breast centers to develop preestablished crisis centers and train staff to better prepare for future device recalls and minimize waste of time. Finally, we believe that implants should be identified based on the characteristics rather than their brand name.

Preliminary Results Supporting the Bacterial Hypothesis in Red Breast Syndrome following Postmastectomy Acellular Dermal Matrix- and Implant-Based Reconstructions.

Acellular dermal matrices have become a mandatory tool in reconstructive breast surgery. Since their introduction, they have been considered to be nonreactive and nonimmunogenic scaffolds. However, some patients who undergo implant-based breast reconstruction with acellular dermal matrices develop postoperative cutaneous erythema overlying their matrices, a condition commonly referred to as red breast syndrome. The aim of this study was to gain a better understanding of this phenomenon. An analysis was conducted on consecutive patients who underwent acellular dermal matrix- and implant-based breast reconstructions and developed red breast syndrome that was treated surgically between April of 2017 and June of 2018 at the authors' institution. During surgery, 1-cm specimens of acellular dermal matrix were sampled and analyzed by scanning electron microscopy. Observations were charted to score and record the presence and thickness of biofilm, and for identification of bacteria. These measurements were performed using Adobe Photoshop CS6 Extended software. Six postmastectomy breast reconstruction patients were included, all with AlloDerm Ready-to-Use-based reconstructions. All specimens were colonized by various bacteria ranging from Gram-negative bacilli to Gram-positive microorganisms. Biofilm was present in all studied specimens. The cause of skin erythema overlying acellular dermal matrix grafts, and the so-called red breast syndrome, may be related to contamination with various bacteria. Although contamination was omnipresent in analyzed samples, its clinical significance is variable. Even if acellular dermal matrix-based reconstructions are salvaged, this could come at the price of chronic local inflammation.

Free Transfer of a Paralyzed Contralateral Little Finger for Total Thumb Reconstruction in an Electrical Burn Patient: A Case Report and Literature Review.

The authors report the case of a 30-year-old male with 52% TBSA high-voltage electrical injury of the upper half of the body. Injuries included a cervical burn with associated alteration of the left brachial plexus as well as extensive soft tissue burn of the right hand. Three months later, he developed osteomyelitis of the right thumb metacarpal bone requiring amputation proximal to the metacarpophalangeal joint. Following initial management, the patient had a permanent distal left upper extremity paralysis with nonfunctional but relatively undamaged ipsilateral hand digits. The right hand remained functional with four intact digits and a thumb stump. Usually, late reconstruction of proximal thumb amputation is performed by pollicization or free toe transfer procedures. In this particular case, right thumb reconstruction was done by free transfer of the left little finger. Four months postoperatively, the patient demonstrated a functional pinch between the reconstructed thumb and the ipsilateral digits along with improving sensation. This uncommon surgical procedure restored a functional thumb with minimal donor site morbidity. The decision-making process and operative technique are presented in detail along with a review of the thumb reconstruction literature.

The double capsules in macro-textured breast implants.

Breast implants are amongst the most widely used types of permanent implants in modern medicine and have both aesthetic and reconstructive applications with excellent biocompatibility. The double capsule is a complication associated with textured prostheses that leads to implant displacement; however, its etiology has yet to be elucidated. In this study, 10 double capsules were sampled from breast expander implants for in-depth analysis; histologically, the inner capsular layer demonstrated highly organized collagen in sheets with delamination of fibers. At the prosthesis interface (PI) where the implant shell contacts the inner capsular layer, scanning electron microscopy (SEM) revealed a thin layer which mirrored the three-dimensional characteristics of the implant texture; the external surface of the inner capsular layer facing the intercapsular space (ICS) was flat. SEM examination of the inner capsule layer revealed both a large bacterial presence as well as biofilm deposition at the PI; a significantly lower quantity of bacteria and biofilm were found at the ICS interface. These findings suggest that the double capsule phenomenon's etiopathogenesis is of mechanical origin. Delamination of the periprosthetic capsule leads to the creation of the ICS; the maintained separation of the 2 layers subsequently alters the biostability of the macro-textured breast implant.

Refining outcomes in dorsal hand coverage: consideration of aesthetics and donor-site morbidity.

BACKGROUND: With high success rates, flap survival should no longer be the sole criterion in judging success in dorsal hand and wrist reconstruction. The authors sought to determine the best flap for dorsal hand coverage in terms of aesthetic appearance, donor-site morbidity, and minimization of revision surgery. METHODS: A retrospective review of all free flaps for dorsal hand and wrist coverage from 2002 to 2008 was performed. Flaps were divided into four groups: muscle, fasciocutaneous, fascial, and venous flaps. Outcomes assessed included need for debulking, blinded grading of aesthetic outcomes, and flap and donor-site complications. RESULTS: A total of 125 flaps were performed with no flap losses. There was no difference in partial loss or infection among the different flap groups. There was a significant range in the need for future debulking procedures, with debulking required in 67 percent of fasciocutaneous, 32 percent of muscle, 5.8 percent of fascial, and 0 percent of venous flaps. There was a significant difference in aesthetic outcomes: venous flaps had the best overall aesthetic outcomes; fascia and muscle flaps scored equally in terms of overall aesthetics, color, and contour match; and fasciocutaneous flaps had significantly worse aesthetic, contour, and color match results compared with all other flap types. Fasciocutaneous flaps had greater donor-site morbidity in terms of need for skin grafting and wound breakdown. CONCLUSION: The aesthetic outcome of dorsal hand reconstruction is dependent on flap choice, with statistically significant differences in revision surgeries and aesthetics among flap types.

Intravenous regional anesthesia administered by the operating plastic surgeon: is it safe and efficient? Experience of a medical center.

BACKGROUND: Intravenous regional anesthesia (Bier's block) is an effective method of providing anesthesia for extremity surgery. This technique is most suitable for short-duration, less than 60-minute surgical procedures in distal extremities. Earlier studies recommended that intravenous regional anesthesia be performed by anesthesiologists who are familiar with the technique and fully trained to treat its complications. This study was conducted to demonstrate that intravenous regional anesthesia administered by the operating plastic surgeon is safe, efficient, and simple to perform. METHODS: A 5-year retrospective chart review (January of 2000 to December of 2004) was undertaken. The study included patients who underwent surgical procedures and were administered intravenous regional anesthesia by the surgeon. RESULTS: Four hundred forty-eight patients were included in the study, and 479 operations of 483 scheduled were completed under intravenous regional anesthesia performed by the operating surgeon. Intravenous regional anesthesia was efficient in 478 of 479 of the cases (99.8 percent). Tourniquet-related technical problems were noted in five of 483 cases (1 percent), resulting in cancellation of four operations, with no reported consequent anesthetic toxicity. Minor complications were reported in six of 479 of the cases (1.2. percent). No major complications occurred. CONCLUSIONS: Despite earlier worries about the safety of intravenous regional anesthesia if not administered by anesthesiologists, the authors found that intravenous regional anesthesia represents a safe and efficient technique of anesthesia for extremity surgery when performed carefully and appropriately by the operating surgeon. The authors suggest that plastic surgeons familiarize themselves with this technique, which is simple to perform. This could probably result in lower overall costs and greater autonomy for the surgeon.
