Document Summary
Spasmodic dysphonia: a permanent voice disorder of a neurogenic nature, can occur to people in their thirties. Adduction type: spasms in vocal folds; intermittent aphonia; strained-strangled voice; dif culty in phonating, monotone, monopitch and monoloudness; shaky voice. Vocal nodules: softer small formations that develop on the vocal folds as a result of vocal abuse, can lead to a hoarse voice or intermittent pitch and phonation breaks. Vocal polyps: can appear when blood vessels rupture and swell as a result of vocal abuse, contrary to nodules, polyps can be the result of a single intense shouting event, leads to a hoarse and breathy voice. Contact ulcers: lesions caused by vocal abuse, can cause pain. Laryngeal webs: membrane connecting one cord to the other, congenital or caused by scar, needs surgical approach. Papilloma: hard wart-like masses, can be removed surgically, but can come back. Ways to talk after after a laryngectomy: we need a new sound source (alaryngeal speech)
