Review of range of arytenoid cartilage motion.

Vocal fold abduction/adduction posturing is key to phonation control. As biomechanical models of the larynx increase in complexity, there is a need to verify them with laboratory data. To help experimental cross-validation of models, ranges of vocal process displacement were reviewed and combined. Although general inter-study agreement was found, there was substantial variation. Using a model of vocal fold posturing, insights were uncovered that could not otherwise be made; best-practice guidelines and research avenues for future studies of vocal posturing were also outlined.
