title: Objectification of the severity of Reinke's edema.
abstract: According to the severity, Reinke's edema (RE) of the vocal folds can be divided into three stages as classified by Yonekawa. We evaluated open and closed quotients of vocal folds vibratory cycles using Videostrobokymography (VSK) in a cohort of patients with RE. Parameters were measured from the anterior, medial and posterior third of the vocal folds. Mean values from RE group were OQ (0.44; 0.46; 0.52); CQ (0.56; 0.54; 0.48). Results from the whole glottis OQ and CQ in RE were: OQ=0.48 and CQ=0.52. Significant differences were found for OQ and CQ mean values as well as values measured from each third of the glottis between the control group and patients with RE. In the first Yonekawa group no statistically significant differences were found compared to the control group, but there were significant differences in the remaining two groups. The correlation between the stage of edema on the Yonekawa classification and the mean values of OQ and CQ was 70%.
