Capsular contracture is one of the most common and trying complications associated with the placement of breast prostheses. The authors hypothesized that silicone implants have a higher rate of capsular contracture than saline implants when used for cosmetic, nonreconstructive breast augmentation. This was based on several previous studies and the experience of the senior author (R.J.R.). The authors objectively evaluated this hypothesis using a systematic review of the literature, specifically examining the incidence of capsular contracture with saline and silicone cosmetic breast implants.
A review of the PubMed, OVID, and Cochrane databases for prospective studies using these implants and having at least 1-year follow-up on all implants was performed. Reference articles of the articles meeting these inclusion criteria were also included. Two independent reviewers performed the same systematic review with the same a priori criteria, and discrepancies were settled by the senior author.
The systematic review was performed in March of 2009. One thousand six hundred ninety-six articles were identified as potentially inclusive based on the search term "breast augmentation." When filtered for "saline or silicone" search terms, 583 articles were found. In the end, 16 articles met inclusion criteria.
There is a lack of current prospective data comparing saline and silicone breast implants in the literature, thereby interfering with the ability of physicians to make data-driven recommendations to patients based on the best medical evidence. The authors were unable to accept or reject their null hypothesis definitively based on this review.
包膜挛缩是与乳房假体放置相关的最常见且最棘手的并发症之一。作者假设,在用于美容而非重建性乳房增大的情况下,硅胶植入物的包膜挛缩发生率高于盐水植入物。这是基于几项先前的研究以及资深作者(RJR)的经验。作者通过对文献的系统回顾客观地评估了这一假设,专门研究了盐水和硅胶美容乳房植入物的包膜挛缩发生率。
对 PubMed、OVID 和 Cochrane 数据库中使用这些植入物的前瞻性研究进行了回顾,所有植入物均有至少 1 年的随访。还包括符合这些纳入标准的文章的参考文献。两位独立的审查员使用相同的预先设定的标准进行了相同的系统评价,分歧由资深作者解决。
系统评价于 2009 年 3 月进行。根据搜索词“乳房增大”,确定了 1696 篇可能包含的文章。在过滤了“盐水或硅胶”的搜索词后,发现了 583 篇文章。最后,16 篇文章符合纳入标准。
文献中缺乏比较盐水和硅胶乳房植入物的当前前瞻性数据,从而妨碍了医生根据最佳医学证据为患者提供基于数据的建议的能力。作者无法根据这篇综述肯定或否定他们的零假设。
