[Mucosal bridge of the vocal fold].

Mucosal bridge of the vocal fold is a newly recognized laryngeal disease need to be differentiated from the functional voice disorder. A 16-year-old woman with deteriorating hoarseness presented for indirect laryngoscopy and laryngofiberoscopy of just slight swelling of the bilateral vocal folds. Since the laryngeal stroboscopy revealed the decrease of wave formation at the swelling portion, we performed an endolaryngeal microsurgery and discovered a sulcus in a side of the vocal fold and a mucosal bridge in the other side. Resection of the bridge followed by the voice therapy increased the voice range and decreased the hoarseness. This case suggests that the laryngeal stroboscopy and microscopic examination with direct laryngoscopy are the most important for diagnosing the mucosal bridge of the vocal fold.
