Historical and pedagogical justification for a train-the-trainer curriculum in microsurgical education: a narrative review

This review explores the pedagogical foundations and traces the evolution of microsurgery training from early 20th-century pioneers to modern simulation—highlighting the shift from live to non-living training models, the emergence of simulation-based practice, and the push toward standardized instruction and formal curricula. Drawing on over 40 years of leadership in microsurgical education, Columbia University Microsurgery Training and Research Lab has recently developed the Train the Trainer (TTT) course as a structured curriculum to certify experienced microsurgeons as instructors. The course covers effective teaching techniques, core microsurgical principles, and hands-on practice with non-living and simulation models, while emphasizing educational philosophy and curriculum design principles. Participants learn to assess trainee progress, deliver constructive feedback, and communicate across diverse learning styles and cultural backgrounds. Together, these developments underscore the importance of a formal TTT curriculum in standardizing and advancing microsurgical education and set the stage for the detailed curriculum modules described in the second companion paper.
