A Bibliometric Review of Capsular Contracture in Breast Implant: Global Trends and Research Hotspots

Introduction: Capsular contracture (CC) is the most common complication following breast augmentation and reconstruction. Although numerous risk factors and preventive strategies have been proposed, the etiology remains poorly understood. This study employs bibliometric analysis to evaluate global research trends, collaboration networks, and emerging hotspots in CC research. Methods: We queried the Web of Science Core Collection using keywords related to breast implants and CC, including publications through December 31, 2024. Data including publication year, author, institution, citations(C), and keywords were analyzed using VOSviewer, Microsoft Excel, and Scimago Graphica to visualize trends, collaboration networks, and research foci. Results: A total of 2065 publications(P) were included. The United States led in both total publication output and citation count (P = 800, C = 27 984), with Harvard (P = 48, C = 1688) and Georgetown Universities (P = 45, C = 2750) being key contributors. Emerging contributions from Asian institutions were noted, though citation impact remained lower. Plastic and Reconstructive Surgery was the most prolific and cited journal (P = 473, C = 23 113). Recent research hotspots identified through keyword analysis include Biofilm, Acellular Dermal Matrix (ADM), Implant placement, contamination, and inflammation. Most top-cited studies were of Level IV or V evidence. Conclusion: Research on CC is increasing, with a shift toward exploring biological mechanisms like biofilm formation and preventative measures such as ADM and implant positioning. Despite growing international interest, most evidence remains low quality. Future work should prioritize clinical studies that generate higher level of evidence and foster broader global collaboration to improve patient outcomes and refine surgical practices.
