Objective To evaluate the effect of head-mounted video system in the teaching of free flap reconstructive
surgery. Methods A total of 45 surgeons with further study program in the Department of Plastic and Reconstructive Surgery
of Shanghai Ninth People's Hospital from June 2022 to December 2023 were included and randomly divided into experimental
group (n=23) and control group (n=22). Both groups were given lectures about basic theoretical knowledge and surgical
procedure before operation. The experimental group observed the surgery by video system, and the video data was directly
taken from the head-mounted video device of the operator and accompanied by explanation, while the control group was
observed in the operation room. The basic theoretical assessment, surgical procedure assessment and teaching satisfaction
rate were compared between the two groups. Results The scores of surgical procedure assessment and teaching satisfaction
rate of experimental group were higher than those of control group, the difference was statistically significant( P<0.05), but
there were no statistically significant difference in the basic theoretical assessment scores between the two groups (P>0.05).
Conclusion The head-mounted video system can improve the teaching effect and teaching satisfaction of flap reconstructive
surgery, which has certain promotion significance.
