Abstract
Background Time spent under the microscope is often a limiting factor as plastic surgery residents
work toward proficiency in microsurgery. This study describes and assesses a novel
application of a digital microscope compatible with smart devices which can consistently
and reliably magnify microsurgical fields.
Methods A digital microscope was used to display an “operating” field on a tablet device.
Two junior plastic surgery residents participated in multiple training sessions. During
each session, residents completed two sessions of a knot-tying task and a chicken
vessel anastomosis task. The sessions were recorded on the tablet, photographed, and
graded by an experienced microsurgeon utilizing three standardized microsurgery training
scales (OWOMSA, OSATS, and Global scale) for evaluation. Between sessions, the residents
received feedback from the experienced microsurgeon.
Results Statistically significant improvements (p < 0.05) in microsurgical technique were observed across 16 areas assessed by the standardized
evaluation scales. Additionally, the residents' surveys suggest favorable attitudes
toward the digital microscope and its value as a training device.
Conclusion Traditional operating microscopes present considerable barriers for effective microsurgical
training. The digital microscope analyzed in the present study provides solutions
to several of these barriers: it is economical, lightweight, portable, and can be
set up by the trainee on any flat surface; photographing and recording capabilities
via the connected tablet device make the digital microscope setup optimized for education.
Our study demonstrates measurable improvements in trainee's skills with use of—as
well as favorable trainee attitudes toward—the digital microscope, which could present
a valuable addition to plastic surgery education.
