This condition is recognized endoscopically by the presence of a linear groove
or furrow which runs along the medial edge of the true vocal folds.

Examination under anaesthesia showing the affected area caused by sulcus vocalis (arrows). The epithelium is directly stuck onto the vocal ligament resulting in bowing and phonatory gap with loss of mucosal waves on laryngeal videostroboscopy.
Figure shows scarred right vocal fold (yellow ellipse) with sulcus and loss of tissue of its free edge (green ellipse). The opposite vocal fold showed similar pathology with an obvious tissue loss (+).
