Cosmetic surgery represents 20 to 30 percent of total plastic surgical volume. The authors hypothesize that with current capitalization and market share, cosmetic surgery should be proportionally represented in scientific innovation.
All journals that may contain articles relevant to plastic surgery were selected from the 2016 edition of Journal Citation Reports. The authors identified, reviewed, and analyzed the 100 top-cited plastic surgery clinical articles using the Science Citation Index Expanded (1900 to 2017) as a proxy for innovation.
The top-100 articles were cited a median of 329.5 times (range, 240 to 1709 times). Sixteen journals were represented, led by Plastic and Reconstructive Surgery (45 percent) and Annals of Surgery (15 percent). Fifty-six percent were reconstructive, 13 percent were breast, 11 percent were pediatric/craniofacial, 11 percent were cosmetic, and 9 percent were hand/peripheral nerve articles. Only 11 percent of articles represented level of evidence I or II, with the majority (79 percent) of articles being level IV. Sixty-seven percent of publications originated from United States. The 11 cosmetic articles originated from different subspecialties: injectables, fillers, and fat grafting (n = 7); contouring (n = 2); facial cosmetic (n = 1); and general cosmetic (n = 1).
Cosmetic innovation is not keeping up with reconstructive innovation; it is unknown why cosmetic surgery is lacking. The authors offer several speculations as to why there is a gap in cosmetic surgical research and, by proxy, innovation.
美容外科约占整形外科学术总量的 20%至 30%。作者假设，按照目前的资金和市场份额，美容外科应该在科学创新中占有相应的比例。
从 2016 年期刊引证报告中选择可能包含整形外科学术文章的所有期刊。作者使用科学引文索引扩展版（1900 年至 2017 年）作为创新的代表，确定、回顾和分析了前 100 篇高引的整形外科学临床文章。
前 100 篇文章的平均被引频次为 329.5 次（范围为 240 次至 1709 次）。有 16 种期刊被引用，其中以《整形与重建外科》（45%）和《外科学年鉴》（15%）为主。56%为重建性文章，13%为乳房文章，11%为小儿/颅面外科文章，11%为美容文章，9%为手部/周围神经文章。只有 11%的文章代表了证据水平 I 或 II，而大多数（79%）文章为证据水平 IV。67%的出版物来自美国。11 篇美容文章来自不同的亚专业：注射剂、填充物和脂肪移植（n=7）；轮廓（n=2）；面部美容（n=1）；以及普通美容（n=1）。
美容创新跟不上重建创新；尚不清楚为什么美容外科缺乏创新。作者对为什么在美容外科研究中存在差距，以及由此产生的创新差距，提出了一些推测。
