单期重建的皮下缩腔切除术，是几年前提出的一种对于拥有大而下垂乳房的女性来说被认为是肿瘤学上安全的手术程序。本研究描述了一种新技术，即J型疤痕皮下缩腔乳房重建术，该术中采用了乳房前扩张器和无细胞基质（Braxon fast），适用于那些需要乳房缩小手术并因治疗或预防性目的需要截肢的拥有大而下垂乳房的患者。我们在2021年1月至2022年12月期间，由意大利乌迪内市的圣玛利亚第米谢尔考迪亚大学医院整形外科部门进行了这种手术的35个乳房的19位女性病例系列，随访中位数为15个月。J型疤痕的优点在于降低了皮肤坏死风险，降低了乳房底部下垂的率，简化了手术设计，并减少了不涉及乳房内侧象限的疤痕对患者的影响。患者在手术后3个月进行了“乳房Q 2.0”术后问卷调查，结果显示对重建效果的满意度较高。因此，我们认为这种手术技术对于乳房丰满且经过适当捏取检测并希望进行治疗/预防性截肢并立即进行异种重建的患者是一个有效的选择。版权所有©2023年由美国整形外科学会取得。

Skin reducing-mastectomy, described several years ago, for single stage reconstruction is considered an oncologically safe procedure and is used in those woman with large and ptotic breasts. This study describes a new technique, the J-pattern skin-reducing breast reconstruction with prepectoral implant and acellular dermal matrix (Braxon fast), which is indicated to patients with large and ptotic breasts who would benefit from a breast reduction and need a mastectomy for curative or prophylactic purpose. We present our case series on 35 breasts in 19 women submitted to the above mentioned procedure from January 2021 to December 2022 at the Plastic and Reconstructive Surgery Department of the University Hospital Santa Maria della Misericordia of Udine, Italy, with a median follow up of 15 months. The advantages of the J scar and consist in a reduced risk of skin necrosis, a reduced bottoming out rate, a simplification of the surgical design and a lower impact of scars not involving the medial quadrants of the breast. Patients were administered the Breast Q 2.0 post-operative questionnaire at 3 months postoperatively, which showed a high average level of satisfaction with the reconstruction. We therefore believe that this surgical technique is a valid option in patients who have a voluminous breast and an adequate pinch test and wish to undergo a curative/prophylactic mastectomy with immediate heterologous reconstruction.Copyright © 2023 by the American Society of Plastic Surgeons.
