Historical Roots of Modern Plastic Surgery: A Cited Reference Analysis.

[BACKGROUND] Highly cited publications are referred to as citation classics and can signify important contributions to a discipline. Although citation classics in plastic surgery have been identified, none were published before 1960. Citation classics in earlier periods may contain the historical roots or intellectual origins of the field. We set out to identify such scholarly works and analyze their characteristics.

[METHODS] A novel technique of citation analysis, referred to as reference publication year spectroscopy, was used to analyze the literature. The spectrogram revealed distinct peaks before 1960, which corresponded to 20 citation classics. These 20 references were then analyzed with respect to historical context, topic of interest, anatomical region, originality, and if authors were named for their findings (eponyms).

[RESULTS] Twenty distinct citation classics (published from 1851 to 1959) were identified, accounting for 430 literature citations. Salmon's "Arteres de la Peau" was the most cited reference, followed by Gillies' "Principles of Plastic Surgery" and Neuber's "Fat Grafting." The theme of angiosomes was highly represented. Most citation classics dealt with reconstruction of acquired defects (37%) and primarily focused on the head and neck regions (45%). Thirty-five percent of clinical studies were noted for their originality, and 5 studies earned their authors' eponymous distinctions.

[CONCLUSION] The roots of modern plastic surgery began in the late 19th century with early efforts to describe cutaneous vasculature. Historical studies that either establish principles or lead to an advancement in our reconstructive methods have the best chance of achieving classical status.
