Respiratory-Based problems
Laryngeal cancer
The aging voice
Deaf and hard of hearing
Pediatric
Professional voice users
Transgender
Airway obstructions
Asthma
Emphysema
Faulty breath control
PVFM
Tracheostomy
Medical intervention
Laryngectomy
Counseling and communication options
Voice is not affected in a sensorineural hearing loss
Until the loss exceeds 50 dB in frequencies under 2000 Hz
Voice charateristcs in deaf or profoundly hard of hearing people
Elevated F0 Varied pitch and loudness changes Downward formant shifts Resonance variations
Speech characteristics of those people Slower rate of speech by prolonging vowels Variations in the prosody or melody of speech
Voice training for the severely hearing-impaired people should not begin
Until efforts are made to provide needed amplification.
2 common causes Structural and lesion mass airflow
interference Abnormal laryngeal movement
interference
2 types of airway obstructions Airflow interference Vocal fold paralysis
2 common causes Infectious
Epiglottis and supraglottal structures Result of bacterial infection
Subglottal obstruction Croup – a viral disease
Noninfectious – space occupying lesions Carcinoma Large cysts
treaments Infectious
Antibiotic therapy Corticosteroids etc.
Noninfectious – space occupying lesions Radiations therapy Surgical reduction or removal of the lesions
Mostly is larngeal paralysis
2 common types Unilateral
Contributes to some compromise of the open airway
Bilateral Bilateral abductor paralysis
A life-threatening obstacle of the open airway
Nonorganic disorder of the upper airway Both true and false VFs
Exhibiting paradoxical function of closure on
Inspiration Expiration Combination of them
Symptoms of respiratory distress do not respond to treatment for asthma
An excellent description and photograph of larynx during a PVFM inspiration
The membranous portion of the folds adducted
With a posterior triangular glottal chink
3 common causes Psychogenic
In conversion reaction Visceral (本能的 )
Related to irritation from LPR Upper airway sensitivity
Neurological A form of laryngeal dystonia
Aware of abnormal and normal VF positioning during inspiration and expiration
Voice therapy Yawn sign Nasal inspiration Working on /s/ duration Use of diaphragmatic-abdominal
breathing Videoendoscopic biofeedback
