Videolaryngostroboscopic pictures and videostrobokymographic illustration of vocal fold anatomy and function, preoperative (upper row) vs. postoperative (lower row). Example A (left side): 45-year-old male professional theater actor with a flat hyperkeratotic lesion of the right vocal fold. Example B (right side): 32-year-old female medical doctor with an exophytic tumor of the right vocal fold. Findings three months postoperatively show: pT1a completely removed, healing process finished, vocal folds with straight margin, complete glottal closure, and restored phonatory mobility (A: normalized, regular and symmetric oscillations; B: oscillations with scarring-related reduced amplitude and phase shift).
