Despite a successful outcome, fat grafting as a procedure has remained relatively dormant until recent years. Now- adays, it is one of the most commonly performed pro- cedures carried out by plastic surgeons worldwide. This renaissance in fat grafting is reflected in the medical literature, with a rapidly growing subsection devoted to autologous fat transplantation. Fat grafting, however, remains a contentious issue within plastic surgery with no consensus as to how to optimally perform the procedure. Various methods of harvesting and transfer have been described, and the published results vary considerably. Despite a rapidly growing volume of articles pertaining to fat grafting in the medical literature, it remains unclear as to which articles have been the most influential on this field. A citation is an abbreviated alphanumeric expres- sion that supports the relevance given by the author to the work of others on a subject of discussion in which the citation appears. The citation number of a published piece of work is the most recognized meth- od of assessing its relative importance to a specific area. 3 Although it is the most-used mode of gauging the influence of a body of work, it is an inherently Copyright © 2015 The Authors.

Received for publication September 5, 2014; accepted November 24, 2014. Background: There has been substantial rise in the volume of published works on fat transfer in the medical literature in the past 25 years, and this is indicative of its growing popularity. However, many unanswered ques- tions remain, and there is no consensus as to the optimum technique. Con- sequently, the scientific and clinical research on fat grafting continues to increase rapidly. The purpose of our study was to perform a bibliometric analysis of the most-cited articles in fat transfer. Methods: Through the Web of Science, all articles relating to fat grafting were identified in the plastic and reconstructive literature. The 100 most- cited articles were identified and analyzed individually. Results: Total citations ranged from 35 to 363 and the most-cited paper by Sidney Coleman was published in Plastic and Reconstructive Surgery. The United States produced 46% of the most-cited papers, and the University of California was the most prolific institution. Twenty-one articles focused on lipofilling to the face while 14 articles looked at fat grafting to the breast. Conclusions: The scientific relevance of a published work is reflected in the number of citations from peers that it receives. Therefore, the 100 most- cited papers in fat grafting have been the most influential articles on this field, and they are likely to be the ones that are remembered most.
