Study Notes
Voice Disorders
- Voice disorders can have a significant impact on an individual's life, affecting their academic, social, psychological, and vocational abilities.
Processes of Speech Production
- Respiration, phonation, resonation, articulation, and prosody are the five processes involved in speech production.
Anatomy and Physiology of Voice Production
- The larynx is responsible for phonation, airway protection, assisting in swallowing, and helping in activities that require highly elevated abdominal pressures.
Incidence and Prevalence of Voice Disorders
- The incidence and prevalence of voice disorders are not precisely known due to conflicting definitions, methodological differences, and varying patient populations.
- According to Roy et al. (2005), nearly 7% of respondents had a voice disorder at the time of the interview, and nearly 30% had experienced a voice disorder at least once in their lifetime.
- Cohen et al. (2012) reported that about 1% of patients received a diagnosis of dysphonia, with females being almost twice as likely as males to be diagnosed with dysphonia.
Classification of Voice Disorders
- Stemple (2007) classified voice disorders into congenital laryngeal pathologies, pathologies of the vocal fold cover, neurogenic laryngeal pathologies, and pathologies of muscular dysfunction.
- Boone et al. (2020) suggested a classification of voice disorders into muscle tension voice disorders, functional voice disorders, psychogenic voice disorders, and organic voice disorders.
Types of Voice Disorders
- Muscle Tension Dysphonia (MTD) is the most common voice disorder, resulting from overuse of the respiratory, laryngeal, and supralaryngeal systems, and can lead to secondary tissue changes.
- Psychogenic voice disorders can result from severe emotional trauma or conflict, leading to functional dysphonia or functional aphonia.
- Organic voice disorders are related to structural deviations or diseases of specific structures of the vocal tract.
