Regeneration of Vocal Fold Mucosa Using Tissue-Engineered Structures with Oral Mucosal Cells

Glottal closure was achieved at the posterior portion by suturing the bilateral cartilaginous portion of the vocal folds of the excised larynges. A contact microphone was attached firmly to the excised larynges and connected to the laryngostroboscope. Experimental phonation was artificially induced by blowing air through the trachea. The upper surfaces of the vocal folds were illuminated by the stroboscopic light from the laryngostroboscope via a flexible endoscope. Vocal fold vibrations were recorded by a video processor.
