Association between operation- and operator-related factors and surgical complications among patients undergoing free-flap reconstruction for head and neck cancers: A propensity score-matched study of 1,865 free-flap reconstructions.

In a hospital that consisted of surgeons with high-volume or very-high-volume experience, the operators or operation experience were not significantly associated with the surgical complications. Only a longer operation time was associated with surgical complications in the patients who underwent free-flap reconstruction for head and neck cancer.
