Different laryngeal images during phonation. a points out the vocal folds and the glottal gap; this video sequence presents a complete closure of the vocal folds. b, c present a glottal chink in the posterior part of the vocal folds which means that they do not have a complete closure. Additionally c has a occlusion in the anterior part of the glottis caused by the arytenoid cartilages. a, b and c show black artifacts due to reflections of the light inside the tube of the endoscope that carries the camera
