(similar to nodules)

How do you treat polyps?
- try voice therapy first
- often need laser surgery to fix
- still need voice tx after surgery
268
Do polyps normally resorb with just voice tx?
no
269
What is Reinke's edema?
swelling in Reinke's space (swelling to the superficial layer of the lamina propria)
270
Is Reinke's edema usually unilateral or bilateral?
bilateral, but assymetrical
271
Do you see chinks in the vocal chords with Reinke's edema?
not usually
272
Does mass of the vocal folds increase with Reinke's edema?
yes, and pitch decreases
273
What will the vocal folds be like with Reinke's edema?
floppy
274
What is Reinke's edema strongly associated with?
smoking, reflux, and hyperfunction
275
What is the natural reaction of the folds when they are being misused?
get swollen
276
Is Reinke's edema most likely in women or men?
women
277
What does someone's voice sound like if the have Reinke's edema?
husky and low pitched
278
What are perceptual signs of Reinke's edema?
- low pitch
- hoarseness
- shortness of breath possible (because of possibly compromised airway)
- likely see decreased pitch range
279
What are the acoustic signs of Reinke's edema?
- low fundamental frequency (a woman will have a fundamental frequency of around 108 Hz)
- increased jitter and shimmer
- spectral noise
280
What are physiological signs of Reinke's edema?
- large fluid filled folds
- huge excursion of the mucosal wave
- likely will see complete closure
281
What is laryngitis?
inflammation of the larynx including the vocal folds
282
What is the medical term for laryngitis?
erythema
283
What is laryngitis caused by?
- exposure to noxious agents (organic)
- reflux (organic)
- dust and allergens (organic)
- vocal abuse (functional)
284
What happens if you continue to use your voice after you have laryngitis?
could cause other things like nodules or atrophy to the vocal folds
285
What are perceptual signs of laryngitis?
- roughness
- hoarseness
- dryness of the throat
- sore throat
286
What are acoustic signs of laryngitis?
- increased jitter and shimmer
- reduced frequency and intensity ranges
- variable frequency
- high spectral noise
287
What are some physiological signs of laryngitis?
- red tissue
- epithelium appears thickened
- movement of the folds is often asymmetrical or aperiodic
- reduced mucosal wave
288
What is ventricular dysphonia?
when someone is using their false folds to vibrate
289
What is often happening during ventricular dysphonia?
the false folds are "loading" on top of the true folds and the sound is a combination of both the folds
290
What does ventricular dysphonia sound like?
- monotone
- low in pitch
- diplophonia
- unpleasent
291
What is a psychogenic voice disorder?
when there are underlying psychological factors causing a person to use their voice differently
292
are people who have psychogenic often completely aphonic?
yes
293
What are things you can do to try and get people with a psychogenic voice disorder to phonate?
ask them to cough, throat clear, hum, laugh, say "mhm"
294
what do people who loose their voice get when people give them a lot of attention for not having a voice?
secondary gain
295
Why don't psychogenic voice patients often not respond well with voice therapy?
it isn't getting to the root of their problem
296
What are the 4 types of psychogenic voice disorders?
- puberphonia
- functional aphonia
- functional dysphonia
- somatization (Briquet's dysphonia)
297
What are some techniques you can use to get a patient to get to their normal voice when they have puberphonia?
- coughing
- digital manipulation
- use masking
- encourage glottal fry
298
What is functional aphonia?
when a person speaks in a whisper
299
What are some voice treatments for functional aphonia?
reflexive voicing tasks
300
What is functional dysphonia?
when someone has some voice but it's abnormal
301
What causes functional dysphonia?
often an imbalance between respiration, phonation and resonance
302
How can you assess stimulability for functional dysphonia?
- matching pitch
- matching loudness
- match other qualities
303
What is somatization/Briquet's dysphonia?
some true psychological trauma has caused a patient to loose their voice
304
What type of psychogenic voice disorders is most resistant to change?
somatization/Briquet's dysphonia
305
What is a conversion disorder?
a psychological trauma is converted into a physical symptom
306
Which psychogenic disorder is considered a true conversion disorder?
Briquet's dysphonia
