Abstract
With improvement in mastectomy skin flap viability and increasing recognition of animation deformity following sub-pectoral implant placement, there has been a transition toward pre-pectoral breast reconstruction. While studies have explored the cost effectiveness of implant-based breast reconstruction, few investigations have evaluated cost with respect to pre-pectoral versus sub-pectoral breast reconstruction. A retrospective review of 548 patients who underwent mastectomy and implant-based breast reconstruction was performed from 2017 to 2020. The demographic and surgical characteristics of the pre-pectoral and sub-pectoral cohorts were well matched, except for reconstructive staging, as patients who underwent pre-pectoral reconstruction were more likely to undergo single-stage instead of two-stage reconstruction. Comparison of institutional cost ratios by reconstructive technique revealed that the sub-pectoral approach was more costly (1.70 ± 0.44 vs 1.58 ± 0.31, p < 0.01). However, further stratification by laterality and reconstructive staging failed to demonstrate difference in cost by reconstructive technique. These results were confirmed by multivariable linear regression, which did not reveal reconstructive technique to be an independent variable for cost. This study suggests that pre-pectoral breast reconstruction is a cost-effective alternative to sub-pectoral breast reconstruction and may confer cost benefit, as it is more strongly associated with direct-to-implant breast reconstruction.

Abstract
INTRODUCTION Prepectoral implant-based breast reconstruction (PIBR) has regained popularity, despite decades-long preference for subpectoral implant placement. This paper aims to compare patient-reported outcomes (PRO) between prepectoral and subpectoral approaches to implant-based breast reconstruction (IBBR). The primary PRO was with the BREAST-Q, and postoperative pain scores, while the secondary outcomes were complication rates. METHODS A comprehensive literature search of the PubMed library was performed. All studies on patients undergoing IBBR after mastectomy that compared prepectoral to subpectoral placement and PROM or postoperative pain were included. RESULTS A total of 3789 unique studies of which 7 publications with 216 and 332 patients who received prepectoral and subpectoral implants, respectively, were included for meta-analysis. Patients with prepectoral implant placement had significantly higher satisfaction with the outcome (p = 0.03) and psychosocial well-being (p = 0.03) module scores. The pain was lower in patients with prepectoral implants on postoperative day 1 (p<0.01) and day 7 (p<0.01). The subgroup analysis of prepectoral breast implants showed that complete acellular dermal matrix coverage had lower rates of wound dehiscence (p<0.0001), but there were no significant differences in complications between one-stage and two-stage procedures. CONCLUSION Overall, patients with prepectoral implants reported higher BREAST-Q scores and lower postoperative pain and lower complications rates than patients with subpectoral implants. In appropriately selected patients, prepectoral implant placement with ADM coverage, be it the primary placement of an implant or placement of a tissue expander before definitive implant placement, should be the modality of choice in patients who choose IBBR. Further research should focus on patient selection, strategies to reduce cost and cost-benefit analysis of PIBR.

Abstract
BACKGROUND Nipple-sparing mastectomy (NSM) with immediate prosthetic breast reconstruction (IPBR) is an oncologically accepted technique that allows to improve aesthetic results and patient quality of life. Traditionally, implant for reconstruction have been placed in a submuscolar (SM) plane, beneath the pectoralis major muscle (PMM). Recently, prepectoral (PP) placement of prosthesis is increasingly used in order to avoid morbidities related to manipulation of PMM. The aim of the present study was to report our experience with 209 NSMs and IPBR using a prepectoral approach and polyurethane-coated implant without acellular dermal matrices (ADMs). METHODS A retrospective review of breast cancer patients who underwent NSM followed by PP - IPBR from January 2018 to April 2021 was performed. Data were recorded in order to evaluate operative details, major complications and oncological outcomes. Aesthetic results and patient quality of life were measured by a specific "QOL assessment PRO" survey. RESULTS Two hundred and nine patients (269 breasts) with PP - IPBR after NSM were included. Mean age was 47 (25-73) years and median follow-up was 14 (1-40) months. A simultaneous contralateral implant-based mammoplasty of symmetrization after unilateral NSM was carried out in six of 149 (4%) patients. Implant loss was observed in three of 209 patient (1.44%); two of 209 (0.96%) patients developed a full-thickness NAC necrosis that required excision. During follow-up one local relapse (0.48%) and two regional nodes recurrences (0,96%) was observed. Patient satisfaction, assessed using a personalized QOL Assessment PRO survey, in term of aesthetic results, chronic pain, shoulder dysfunction, sports activity, sexual and relationship life and skin sensibility, was excellent. CONCLUSIONS Our experience shows that PP-IPBR using polyurethane-coated implant after NSM is a safe, reliable and effective alternative to traditional IPBR with excellent aesthetic outcomes and high patient quality of life; it is easy to perform, minimizes complications related to manipulation of PPM and reduces operative time while resulting also in a cost-effective technique.

Abstract
Background Bilateral risk-reducing mastectomy (BRRM) has increased its popularity in the last years because of its aim to minimise the chances of developing breast cancer in high-risk patients. Women undergoing this procedure must be considered highly demanding patients given the need to combine aesthetical, functional and preventive desires. This study aims to present the authors' experience in performing BRRM followed by single-stage prepectoral reconstruction (PPBR) with implant completely covered by acellular dermal matrix (ADM) and to report indications, surgical techniques, functional and aesthetic results. Methods A single-centre prospective data collection was carried out from January 2017 to January 2021 of patients at high risk of developing breast cancer undergoing BRRM and immediate PPBR with ADM. Patients were subdivided into two groups according to the breast shape: Group A had small and medium size breasts and Group B had large and ptotic breasts. Oncological and surgical outcomes were collected. Satisfaction with reconstruction and related quality of life were evaluated through the BREAST-Q questionnaire. Results A total of twenty-three patients met the inclusion criteria. Seventeen patients were included in group A and six patients in group B. Average follow-up was 18.4 months. Minor complications occurred in four breasts: one seroma, one hematoma and two cases of wound dehiscence. Capsular contracture was not observed. All patients were satisfied with the final result according to the post-operative BREAST-Q questionnaire. Conclusions Immediate prepectoral breast reconstruction could represent the ideal reconstruction option after BRRM and should be offered to all women that fulfil the inclusion criteria.

Abstract
BACKGROUND To assess the impact of animation deformity on health-related quality of life, a content-specific, valid, and reliable patient-reported outcome measure is needed. This report describes the development and validation of the BREAST-Q Animation Deformity scale. METHODS Women with breast cancer who had an implant-based reconstruction provided data. In phase 1 (January 2017 and December 2018), qualitive and cognitive patient interviews and expert input were used to develop and refine scale content. In phase 2 (March to June 2019), a field test study with members of the Love Research Army (LRA) was conducted. Rasch Measurement Theory (RMT) analysis was used to examine psychometric properties. RESULTS In phase 1 of the study, qualitative (n = 11) and cognitive (n = 4) interview data and expert input (n = 9) led to the development of a 12-item scale measuring animation deformity. In phase 2, 651 LRA members provided data and 349 participated in a test-retest study. In the RMT analysis, the data fit the Rasch model (X2(96) = 104.06; p = 0.27). The scale's reliability was high, with person separation index and Cronbach alpha values with/without extremes of ≥ 0.84 and ≥ 0.92 respectively, and an intraclass correlation coefficient of 0.92 (95% confidence interval, 0.90-0.94). Mean scores on the Animation Deformity scale varied as predicted across subgroups of participants who reported differing amounts of change in breast appearance when their arms were lifted overhead or when they lifted something heavy, and for increasing happiness with the overall outcome of their breast reconstruction. CONCLUSION The 12-item Animation Deformity scale forms a new scale in the BREAST-Q Reconstruction Module that can be used in comparative effectiveness research or to inform clinical care.

Immediate Prosthetic Breast Reconstruction after Nipple-Sparing Mastectomy: Traditional Subpectoral Technique versus Direct-to-Implant Prepectoral Reconstruction without Acellular Dermal Matrix. J Pers Med 2021; 11:jpm11020153. [PMID: 33671712 PMCID: PMC7926428 DOI: 10.3390/jpm11020153] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2020] [Revised: 02/18/2021] [Accepted: 02/19/2021] [Indexed: 12/04/2022] Open
Abstract
Background: The aim of this study was to compare outcomes of immediate prosthetic breast reconstruction (IPBR) using traditional submuscular (SM) positioning of implants versus prepectoral (PP) positioning of micropolyurethane-foam-coated implants (microthane) without further coverage. Methods: We retrospectively reviewed the medical records of breast cancer patients treated by nipple-sparing mastectomy (NSM) and IPBR in our institution during the two-year period from January 2018 to December 2019. Patients were divided into two groups based on the plane of implant placement: SM versus PP. Results: 177 patients who received IPBR after NSM were included in the study; implants were positioned in a SM plane in 95 patients and in a PP plane in 82 patients. The two cohorts were similar for mean age (44 years and 47 years in the SM and PP groups, respectively) and follow-up (20 months and 16 months, respectively). The mean operative time was 70 min shorter in the PP group. No significant differences were observed in length of hospital stay or overall major complication rates. Statistically significant advantages were observed in the PP group in terms of aesthetic results, chronic pain, shoulder dysfunction, and skin sensibility (p < 0.05), as well as a trend of better outcomes for sports activity and sexual/relationship life. Cost analysis revealed that PP-IPBR was also economically advantageous over SM-IPBR. Conclusions: Our preliminary experience seems to confirm that PP positioning of a polyurethane-coated implant is a safe, reliable and effective method to perform IPBR after NSM.

Abstract
Prepectoral implant-based breast reconstruction has recently gained increasing popularity, but there are limited data regarding national trends in the use of this technique. Our aim was to determine practice patterns related to prepectoral breast reconstruction among plastic surgeons, as well as to identify perceived advantages and disadvantages of this technique. Methods A 16-question electronic survey tool was distributed to 2535 members of the American Society of Plastic Surgeons. Survey items focused on surgeon practices related to prepectoral reconstruction, in addition to their motivations for and concerns with performing the procedure. Results A total of 274 responses were received (10.8% response rate). Nearly half of respondents (48.4%) reported using prepectoral techniques in all or most of their procedures. Decreased animation deformity was identified as the most significant advantage by 76.3% of respondents. Increased rippling and potential wound healing complications were identified as the most significant disadvantages to the procedure by 49.1% and 40.4% of respondents, respectively. The majority of surgeons reported using acellular dermal matrices in their procedures, with most surgeons demonstrating preferences for cohesive and shaped devices. Conclusions Prepectoral breast reconstruction is being widely adopted by plastic surgeons, with the majority of surgeons in our sample using prepectoral techniques in their practices. Responses demonstrate that this technique offers several perceived advantages, most notably the avoidance of animation deformity. However, our data also highlight that there are still many unanswered questions in the community about the complication profile and technical aspects of prepectoral techniques that warrant further investigation.

Abstract
BACKGROUND As chest reconstructions in Poland syndrome are performed for patients at young ages, patients are generally concerned about conspicuous scars. Meanwhile, a robotic-assisted latissimus dorsi (LD) muscle harvest with inconspicuous scars has been performed for autologous breast reconstruction. As our experience with robotic-assisted LD flap harvest has increased over the years, we have made improvements in surgical techniques to optimize results. The purpose of this study was to introduce and identify the role of the refined robotic-assisted LD muscle flap harvest technique in autologous chest reconstruction in patients with Poland syndrome. METHODS Autologous chest reconstruction using a robotic-assisted LD muscle flap harvest was performed for 21 patients with Poland syndrome. Subjective assessments were performed to evaluate improvement in chest deformity, patient satisfaction with overall outcomes, chest symmetry, and scars. Assessments by the operator and two independent evaluating investigators were carried out with patients' photographs. The complication rates and the time for robotic surgery were also evaluated. RESULTS At the last visit, the average patient grades for improvement in chest deformity, satisfaction with overall outcomes, chest symmetry, and scars were 4.80, 4.72, 4.18, and 4.87, respectively. Assessments by the operator and two independent evaluating investigators demonstrated that improvement in chest deformity was achieved in all patients. No serious complications such as flap loss were recorded for any patient. The time for robotic surgery markedly decreased as experience accumulated. CONCLUSIONS Surgical refinements for robotic-assisted LD flap harvest might be effective and reduce operative times for patients with Poland syndrome.
