Google Trends (GT) provides cost-free, customizable analyses of search traffic for specified terms entered into Google's search engine. GT may inform plastic surgery marketing decisions and resource allocation.
The aim of this study was to determine GT's utility in tracking and predicting public interest in nonsurgical cosmetic procedures and to examine trends over time of public interest in nonsurgical procedures.
GT search volume for terms in 6 ASPS and ASAPS nonsurgical procedure categories (Botox injections, chemical peel, laser hair removal, laser skin resurfacing, microdermabrasion and soft tissue fillers [subcategories: collagen, fat, and hyaluronic acid]) were compared with ASPS and ASAPS case volumes for available dates between January 2004 and March 2019 with the use of univariate linear regression, taking P < 0.01 as the cutoff for significance.
Total search volume varied by search term within the United States and internationally. Significant positive correlations were demonstrated for 17 GT terms in all 6 ASPS and ASAPS categories: "Botox®," "collagen injections," "collagen lip injections" with both databases; and "chemical skin peel," "skin peel," "acne scar treatment," "CO2 laser treatment," "dermabrasion," "collagen injections," "collagen lip injections," "fat transfer," "hyaluronic acid fillers," "hyaluronic acid injection," "hyaluronic acid injections," "Juvederm®," and "fat transfer" with just 1 database. Many search terms were not significant, emphasizing the need for careful selection of search terms.
Our analysis further elaborates on recent characterization of GT as a powerful and intuitive data set for plastic surgeons, with the potential to accurately gauge global and national interest in topics and procedures related to nonsurgical cosmetic procedures.
Google Trends（GT）提供免费的、可定制的搜索流量分析，可针对特定术语输入谷歌搜索引擎。GT 可能会为整形手术的营销决策和资源分配提供信息。
本研究旨在确定 GT 在跟踪和预测公众对非手术美容程序的兴趣方面的效用，并考察公众对非手术程序的兴趣随时间的变化趋势。
使用单变量线性回归比较了 6 个 ASPS 和 ASAPS 非手术程序类别（肉毒杆菌注射、化学换肤、激光脱毛、激光皮肤再生、微晶磨皮和软组织填充物[亚类：胶原蛋白、脂肪和透明质酸]）的 GT 搜索量与 2004 年 1 月至 2019 年 3 月期间可用日期的 ASPS 和 ASAPS 病例量，以 P<0.01 为显著性截点。
在美国和国际上，总搜索量因搜索词而异。在所有 6 个 ASPS 和 ASAPS 类别中，17 个 GT 术语均显示出显著的正相关：“Botox®”、“胶原蛋白注射”、“胶原蛋白唇部注射”与两个数据库；以及“化学皮肤脱皮”、“皮肤脱皮”、“痤疮疤痕治疗”、“CO2 激光治疗”、“微晶磨皮”、“胶原蛋白注射”、“胶原蛋白唇部注射”、“脂肪转移”、“透明质酸填充物”、“透明质酸注射”、“透明质酸注射”、“Juvederm®”和“脂肪转移”与仅 1 个数据库。许多搜索词并不显著，这强调了仔细选择搜索词的必要性。
我们的分析进一步阐述了 GT 最近被描述为一种强大而直观的数据集，对整形医生具有潜在价值，可准确衡量全球和国家对与非手术美容程序相关的主题和程序的兴趣。
