The preoperative to postoperative differences in jitter values (jitter and relative average perturbation) were closely correlated to the shimmer values for patients with postoperative vocal fold edemas. In the patients with edema, the preoperative to postoperative differences in jitter had a correlation coefficient of 0.95 (P < 0.0001) to the difference in shimmer, compared with a correlation coefficient of 0.39 (P < 0.0001) in the patients without edema.CONCLUSIONS: This study supports the use of the {"}Best-of-Three{"} procedures for precise and relevant MDVP parameter calculations. The MDVP parameters, with closely correlated changes in jitter and shimmer values, accurately reflect the induced vocal fold edema when using the preoperative to postoperative changes.",
