What VSK reveals about phonation in Reinke’s edema
We evaluated open (OQ) and closed quotients (CQ) of vocal folds (VF) vibratory cycles at three locations (anterior, middle, and posterior glottis) using VSK lines in a cohort of patients with Reinke’s edema (RE). Mean values for OQ were 0.44 at the anterior (a), 0.46 at the middle (m), and 0.52 at posterior (p) locations. The CQ values were 0.56 (a), 0.54 (m), and 0.48 (p), respectively. Results for the whole glottis OQ and CQ were 0.48 and 0.52, respectively. Differences for OQ and CQ measured at each location were significant.
