Voice Disorders Flashcards
Dysphonia
Interruption in the ability to produce a complex, dynamic voice; pitch, loudness and quality
Voice
The complex dynamic product of vocal fold vibration that allows us to vocalize and verbilize, socially and culturally mediated
Pitch
Perceptual quartile of fundamental frequency
Loudness
Perceptual quarilate of amplitude (decibels)
Quality
Harmonics
Classification system of voice disorders
Organic-> laryngeal and neurologic
Functional-> psychogenic and muscle tension Dysphonia
Laryngeal disorders
Cancer
Congenital abnormalities
GERD or LPR
laryngitis
Neurogenic voice disorders
VF paralysis
Spasmodic Dysphonia
Psychogenic voice disorders
Conversion disorder
Mutational falsetto
Excessive muscle tension voice disorders
Vocal fold nodules
Vocal polyps
Instrumental observations
Acoustic- visipitch
Aerodynamic- airflow, air pressure and VF resistance against airflow from the lungs called sub glottal air flow
Direct visualization- laryngoscopy
Direct- rigid, flexible, stroboscopy
Indirect- mirror used to look back (no machines)
Vocal abuse treatment
Vocal hygiene
Respiratory exercises
Loudness reduction
Relaxation training
Neurological disorder treatment
Phonosurgery (thyroplasty)
Botulinum
Lee Silverman voice treatment
Alaryngeal communication
Surgical opening at the trachea (stoma)
Communication without larynx
Tracheoesphageal speech
Surgical procedure creates a hole between the trachea and esophagus Breathe through stoma then cover and air goes through esophagus in order to speak through mouth
