- What theory explains vocal fold vibration as an interaction between muscle tension and airflow forces?
Show answer
The myoelastic-aerodynamic theory- What aerodynamic principle helps pull the vocal folds back together during phonation?
Show answer
The Bernoulli effect (a pressure drop as air speeds through the narrowed glottis)- What model describes the vocal fold as a stiffer outer layer over a more pliable inner body?
Show answer
The cover-body model- What is Reinke's space?
Show answer
The superficial layer of the lamina propria, just under the vocal fold epithelium- What are vocal nodules?
Show answer
Bilateral, callus-like growths on the vocal folds, typically at the junction of the anterior and middle thirds- What most commonly causes vocal nodules?
Show answer
Chronic vocal abuse or misuse (phonotrauma)- What is a vocal fold polyp?
Show answer
A usually unilateral, soft, fluid-filled lesion on the vocal fold, often from a single traumatic vocal event- What is Reinke's edema?
Show answer
Diffuse swelling (fluid buildup) in the superficial lamina propria of the vocal folds, strongly linked to smoking- What commonly causes a laryngeal granuloma?
Show answer
Trauma to the vocal process, such as from intubation or chronic throat clearing- What causes recurrent respiratory papillomatosis?
Show answer
Human papillomavirus (HPV) infection- What is a vocal fold cyst?
Show answer
A fluid- or keratin-filled sac enclosed within the lamina propria of the vocal fold- What is sulcus vocalis?
Show answer
A groove-like indentation along the edge of the vocal fold where lamina propria tissue is missing- What is the most common cause of unilateral vocal fold paralysis?
Show answer
Damage to the recurrent laryngeal nerve, such as from thyroid surgery- What distinguishes vocal fold paresis from vocal fold paralysis?
Show answer
Paresis is partial weakness of vocal fold movement, while paralysis is complete loss of movement- What is spasmodic dysphonia?
Show answer
A neurological voice disorder (focal laryngeal dystonia) causing involuntary spasms of the laryngeal muscles during speech
