Breast augmentation is the most common aesthetic surgery performed in the United States (US) annually. Analysis of Google Trends (GT) data may give plastic surgeons useful information regarding worldwide, national, and regional interest for breast augmentation and other commonly performed aesthetic surgeries.
Data were collected using GT for breast augmentation and associated search terms from January 2004 to May 2017. Case volume was obtained from the American Society of Plastic Surgeons (ASPS) annual reports for the calendar year 2005-2016.
Trend analysis showed that total search term volume for breast augmentation and breast implants gradually decreased worldwide and in the US over the study period while the search term boob job slowly increased. Univariate linear regression demonstrated a statistically significant positive correlation between average annual Google search volume of "breast augmentation" and the annual volume of breast augmentations performed in the US according to ASPS data (R = 0.44, p = 0.018). There was no significant correlation between national volume of breast augmentations performed and search volume using the terms "breast implants" or "boob job" over time (p = 0.84 and p = 0.07, respectively). In addition, there appears to be country specific variation in interest based on time of year and peaks in interest following specific policies.
To our knowledge, this is the first and only analysis of GT data in the plastic surgery literature to date. To that end, this study highlights this large and potentially powerful data set for plastic surgeons both in the US and around the world.

隆胸手术是美国每年进行的最常见的美容手术。对谷歌趋势（GT）数据的分析可为整形外科医生提供有关全球、国家和地区对隆胸及其他常见美容手术的兴趣的有用信息。
使用GT收集2004年1月至2017年5月期间隆胸及相关搜索词的数据。病例数量来自美国整形外科医师协会（ASPS）2005 - 2016历年的年度报告。
趋势分析表明，在研究期间，全球和美国隆胸及乳房植入物的总搜索词量逐渐下降，而“隆胸手术”的搜索词量则缓慢增加。单变量线性回归显示，根据ASPS数据，“隆胸”的年均谷歌搜索量与美国每年进行的隆胸手术量之间存在统计学上显著的正相关（R = 0.44，p = 0.018）。随着时间的推移，美国进行的隆胸手术量与使用“乳房植入物”或“隆胸手术”等术语的搜索量之间没有显著相关性（p分别为0.84和0.07）。此外，基于一年中的时间以及特定政策后的兴趣高峰，不同国家的兴趣似乎存在差异。
据我们所知，这是迄今为止整形外科学文献中对GT数据的首次也是唯一一次分析。为此，本研究向美国和世界各地的整形外科医生突出展示了这个庞大且可能具有强大功能的数据集。
