In the laryngostroboscopic examination, we found a bilateral vocal cord palsy with hyperplastic vestibular folds (Figure 1).
Post-operative finding via laryngoscopy after laterofixation on the right side: The right vocal fold is fixed laterally (white arrow) and thus widens the glottic gap, while the position of the left vocal fold is unchanged (black arrow). The vestibular folds are less swollen.
