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