The Impact of PhD Degrees in Academic Plastic Surgery: An In-depth Analysis of Faculty and Residents

Doctor of Philosophy (PhD) is the highest academic degree awarded by universities in most fields of study. In surgery, it is thought to provide surgeons with skills to conduct high-quality research and advance academically. However, this presumed effect has not been assessed among academic plastic surgeons (APSs) and plastic surgery residents (PSRs). The purpose of this study is to determine the differences in multiple strata of career progression and success between PhD and non-PhD graduates in academic plastic surgery.

We conducted a nationwide cross-sectional study of APSs and PSRs. Departmental websites of integrated plastic surgery residency programs were used to identify our study population and their demographics, degrees, and tenure status. Data on research productivity were collected using Scopus. Information on research funding was gathered through the National Institutes of Health and Plastic Surgery Foundation. To assess the plastic surgery programs' reputations, we divided residency programs into four quartiles (Q1, 1-20; Q2, 21-40; Q3, 41-60; Q4, 61+) according to their Doximity ranking.

We identified 841 APSs (78.5% men) and 948 PSRs (58.1% men), of whom 5.1% and 2.7% had a PhD degree, respectively. PhD graduates had significantly more advanced research portfolios. PhD APSs were more likely to secure research funding, and PhD PSRs were more likely to train at highly reputed programs. However, academic rank and leadership appointments were not significantly influenced by PhDs.

Holding a PhD can strongly advance a plastic surgeon's research portfolio, but it does not guarantee a better position or tenure status.
