Organic Voice Disorder Flashcards
Describe the vocal fold structure
Epithelium Superficial Intermediate Deep- these three form the lamina propria Body (vocalis muscle)
What does the severity of dysphonia relate to
- Site of lesion - does it stop adduction
- Depth of lesion- does it affect the mucosal wave
- Size of lesion- if large enough can cause stridor
- Any compensatory muscle patters- eg change in phonatory setting to compensate
What are vocal fold nodules and how do they occur and present themselves
They are benign Caused by repeated trauma- eg shouting May start as unilateral and develop to bilateral but will not be equivalent in size Surgery could cause scarring Therefore voice therapy is used
What is the difference between acute and chronic laryngitis
Chronic laryngitis does not resolve spontaneously
What is suggested to treat acute laryngitis
Rest
Drinking water
Steam inhalation
What is the difference between vocal nodules and polps
Polp’s are larger and more vascular
What are the three types of polp
Localised
Haemorrhagic
Diffuse polypoid degeneration
What is diffuse polypoid degeneration
Swelling of oedema in Reinkes space. Causes vocal folds to be asymmetrical
Results in low pitched voice
What are the two types of vocal fold cyst
Mucus retention
Epidermoid
Why can VF cysts cause a change in voice
Causes a reduction in the mucosal wave
How are VF cysts treated
Surgery
What are the three types of laryngeal granuloma
- Arytenoid granuloma
- intubation granuloma
- post injection granuloma
What is an arytenoid granuloma
More common in men
Occurs when they use too low a pitch- using too much force
Treatment- voice therapy and reflux medication
What is an intubation granuloma
Trauma to the vocal folds that occurred during intubation
Surgery may be offered if it is restricting airway
What is a post injection granuloma
Occurs in response to vocal fold injection used to treat VF paralysis
