Breast implants can be introduced through a variety of incisions, most commonly an inframammary incision, but also a periareolar incision or an axillary incision. Usually, the implant is inserted through the same incision used in performing an augmentation/mastopexy. Some authors use a separate inframammary incision. Capsular contracture is the most common complication of breast augmentation. One theory holds that it is caused by an infected biofilm, prompting surgeons to minimize implant handling, known as the "no touch" technique. This review was undertaken to investigate the relationship, if any, between the access incision and the risk of capsular contracture.
An electronic literature search was conducted to identify publications comparing capsular contracture rates by the access incision.
Ten studies were evaluated. Most were retrospective series. Three were prospective core studies. Some studies reported an increased risk of capsular contracture for a periareolar incision; a similar number did not. One study supported a separate inframammary incision at the time of vertical augmentation/mastopexy.
Bacterial studies in the last decade show that the resident bacteria on the skin surface and within breast tissue are similar. Sophisticated microbiological evaluation of breast capsules reveals that the microbiome relates to the patient, as opposed to a specific bacterial profile for capsular contracture. A review of the statistics used in determining an advantage for a separate incision at the time of vertical augmentation/mastopexy reveals that there is no statistically significant risk reduction when using an additional inframammary incision, which adds an unnecessary scar.
The access incision at the time of breast augmentation or augmentation/mastopexy is unlikely to affect the capsular contracture risk. There is no need to make a separate incision to insert the implant at the time of augmentation/mastopexy, or to isolate the implant from contact with breast parenchyma. Little evidence supports the "no touch" technique. The etiology of capsular contracture remains unknown.
乳房植入物可以通过多种切口引入,最常见的是乳晕下切口,但也可以是乳晕周围切口或腋窝切口。通常,植入物通过用于进行隆胸/乳房提升的相同切口插入。一些作者使用单独的乳晕下切口。包膜挛缩是乳房增大最常见的并发症。一种理论认为,它是由感染的生物膜引起的,这促使外科医生尽量减少植入物的处理,即所谓的“无接触”技术。进行这项综述是为了研究切口与包膜挛缩风险之间的关系(如果有的话)。
进行了电子文献检索,以确定比较切口处包膜挛缩发生率的出版物。
评估了 10 项研究。大多数是回顾性系列研究。有三项是前瞻性核心研究。一些研究报告乳晕周围切口的包膜挛缩风险增加;类似数量的研究没有报告。一项研究支持在垂直隆胸/乳房提升时使用单独的乳晕下切口。
过去十年的细菌研究表明,皮肤表面和乳房组织内的常驻细菌相似。对乳房胶囊的复杂微生物评估表明,微生物组与患者有关,而不是与包膜挛缩的特定细菌特征有关。对确定在垂直隆胸/乳房提升时使用单独切口的优势所使用的统计数据进行审查后发现,使用额外的乳晕下切口没有统计学上显著的风险降低,这会增加不必要的疤痕。
乳房增大或隆胸/乳房提升时的切口不太可能影响包膜挛缩的风险。在隆胸/乳房提升时没有必要为植入物插入单独的切口,也没有必要将植入物与乳房实质隔离。几乎没有证据支持“无接触”技术。包膜挛缩的病因仍不清楚。
