I. Basis of Voice and Speech Production – Anatomy/Physiology/Terminology A. Glottis = vocal cord area B. Supraglottis= area of larynx above vocal cords (false vocal cords/ arytenoids/epiglottis) C. Subglottis = area of larynx immediately below the vocal cords

I. Basis of Voice and Speech Production – Anatomy/Physiology/Terminology D. Voice = output from the lung and larynx video of normal videostrob E. Speech = communication resulting from modification of voice by the articulators (tongue/lips/palate/teeth) video of dysarthria F. The function of normal vocal cords (a competent glottic valve) converts the DC current of air streaming upward from the lung into an AC current. Voicing: ‘Glottic valve’ convert DC-AC Cough
Slide 6-

I. Basis of Voice and Speech Production – Anatomy/Physiology/Terminology G. The most superficial layer of the vocal cord is fluid. It overlies the mucosal surface of the vocal cord which also contains muscle and ligament. Normal voicing requires this fluid layer to be present – underscoring key components to the treatment of voice disorders: humidification and hydration.

Normal larynx Vocal Folds - Complex Nature Body - Underlying muscle + vocal ligament Cover - Loosely attached epithelium Overlying fluid
Slide 8-

I. Basis of Voice and Speech Production – Anatomy/Physiology/Terminology G. The combination of adequate breath support (lungs) and appropriate vocal cord vibration are needed for normal phonation. [VIDEO of patient with asthenic voice]
Slide 9-

I. Basis of Voice and Speech Production – Anatomy/Physiology/Terminology H. Impaired function of the glottic valve results in an abnormal voice and can also impair swallowing and breathing. [VIDEO of bilateral vocal cord paralysis]
Slide 10-

I. Basis of Voice and Speech Production – Anatomy/Physiology/Terminology I. Passive vibration of the vocal cords rather than active movement by muscle contraction results in voice – this concept explains how a patient with bilateral vocal cord paralysis may have a normal voice. [VIDEO of bilateral vocal cord paralysis #2]
Slide 11-

I. Basis of Voice and Speech Production – Anatomy/Physiology/Terminology J. Phonation can also occur without vocal cords. A man treated with removal (partial laryngectomy) of cancerous vocal cords is able to produce a lung powered sound (voice) by vibration of the arytenoid mucosa against the base of the tongue. [VIDEO of patient below]

II. The Significance of Voice Disorders A. Dysphonia as a tipoff to another illness
Slide 15-

II. The Significance of Voice Disorders B. Voice Professional = singers, doctors, lawyers, teachers, anyone using their voice to work
Slide 16-

III. Understand the functions of the larynx and how disease impairs those functions A. Impaired function of the glottic valve results in an abnormal voice and can also impair swallowing and breathing.
Slide 17-

III. Understand the functions of the larynx and how disease impairs those functions B. Impaired vocal cord/fold vibration results in dysphonia.
Slide 18-

III. Understand the functions of the larynx and how disease impairs those functions C. Example of dysphonia due to abnormal vocal cord vibration from laryngitis. Laryngitis is inflammation of the larynx and can be caused by a. Infection: viral/bacterial/fungal b. Trauma: vocal overuse/intubation c. Exposure to irritants: smoke/GE reflux/inhalants
Slide 19-

IV. How to Evaluate a Patient with a Voice Disorder A. Obtain a History
Slide 20-

IV. How to Evaluate a Patient with a Voice Disorder B. Perform a physical examination

IV. How to Evaluate a Patient with a Voice Disorder C. Methods to image the larynx include:

IV. How to Evaluate a Patient with a Voice Disorder C. Methods to image the larynx include: flexible fiberoptic transnasal exam of the larynx, [VIDEOS of exam]
Slide 23-

V. Identify Common Voice Disorders A. Important voice disorders include infectious, neurogenic, traumatic, psychogenic, and neoplastic causes Viral ALS Scarring Trauma: nodule/polyp Psychogenic Neoplastic
Slide 24-

V. Identify Common Voice Disorders A. Important voice disorders include infectious, neurogenic, traumatic, psychogenic, and neoplastic causes Chronic hoarseness (> 2 weeks or ? >3 months) Neoplastic Glottic cancer: Harsh, breathy voice Supraglottic cancer: “Silent”; muffled voice, neck mass, airway obstruction Subglottic: Airway obstruction RRP (Recurrent respiratory papillomatosis)
Slide 25-

V. Identify Common Voice Disorders A. Important voice disorders include infectious, neurogenic, traumatic, psychogenic, and neoplastic causes Chronic hoarseness (> 2 weeks or ? >3 months) Psychogenic “Functional aphonia” “Psychogenic aphonia” Muscle tension dysphonia
Slide 26-

VI. Management of common voice disorders A. Voice disorders may be managed by physicians who are not capable of examining the vocal cords when the presumptive diagnosis is laryngitis through a. voice rest b. humidification c. hydration d. management of associated symptoms (such as cough) and reflux.
Slide 27-

VI. Management of common voice disorders B. Referral to an Otolaryngologist is indicated when a. there is clinical suspicion that the voice disorder is not a self-limited laryngitis b. the voice problem persists longer than two to three weeks; c. there are associated symptoms such as swallowing or breathing impairment
Slide 28-

VI. Management of common voice disorders C. Medications with adverse effects on the voice include: Drying effect (antihistamines, diuretics, tricyclic antidepressants) Laryngeal irritants (inhaled propellants Factors increasing bleeding risk (aspirin, anticoagulants)
Slide 29-

VI. Management of common voice disorders D. Medications with favorable effects on the voice: Antitussives: codeine/dextromethorphan/benzonatate (Tessalon perles) Mucolytics: guaifenesin Water: H20 (humidification and hydration) Anti-reflux medications (H2 blockers e.g. Zantac /PPI e.g. Prilosec/Omeprazole)
Slide 30-

VI. Management of common voice disorders E. Speech pathologists manage voice disorders by: Assessing vocal behavior Modifying vocal behavior Maximizing vocal potential
