Flashcards in voice Deck (23):
1

partial submucous cleft palate
+ bifid uvula

hypernasality,
decreased intraoral pressure,
difficulties with adequate production of af/fricatives & plosives

2

extrinsic laryngeal muscles: suprahyoids

(elevators)
digastrics,
geniohyoids,
mylohyoids,
stylohyoids,
genioglossus,
hyoglossus

3

total lung capacity

total volume of air in the lungs

4

tidal volume

amount of air inhaled & exhaled during a normal breathing cycle

5

vital capacity

the volume of air that can be exhaled after a maximal exhalation

6

injection method

patient impounds air in the oral cavity,
pushes it back into esophagus,
& vibrates cricopharyngeus muscle

7

vocal fold adduction strategies

would benefit a singer with recurrent laryngeal nerve damage

8

Blom-Singer prosthetic device

Blom-Singer prosthetic device used by laryngectomees to
shunt air from the trachea to the esophagus
so patient can speak on that pulmonary air

9

spasmodic dysphonia treatments

CO2 laser surgery,
recurrent laryngeal nerve resection,
botox,
voice therapy

10

cover-body theory of phonation

the epithelium,
the superficial layer of the lamina propria,
& much of the intermediate layer of the lamina propria
vibrate as a cover on a relatively stationary body
which is made up of
the remainder of the intermediate layer,
the deep layer,
& the TA muscle

11

frequency perturbation

measurements of jitter,

12

amplitude perturbation

measurements of shimmer,
evaluates cycle-to-cycle variation of vocal intensity,
>1 dB of variation may cause dysphonic quality

13

voice: key structures

thyroid cartilage,
cricoid cartilage,
arytenoid cartilages,
corniculate & cuneiform cartilages,
CN X (vagus)

14

voice: key muscles

thyroarytenoids,
cricothyroids,
posterior cricoarytenoids,
lateral cricoarytenoids,
interarytenoids

15

extrinsic laryngeal muscles: infrahyoids

(depressors)
thyrohyoids,
omohyoids,
sternothyroids,
sternohyoids

16

lifespan changes

involve mean F0
& max phonation time

17

sound spectrograph

useful for quantitative analysis of speech,
often used to obtain baseline measurements prior to phonosurgery

18

resonance disorders

hypernasality,
hyponasality,
assimilative nasality,
cul-de-sac resonance

critical to rule out organic causes
(velopharyngeal inadequacy)

19

pathological changes

carcinoma,
vocal abuse,
neurological,
vf irritation
(environmental agents)

20

pathological treatment

medication,
surgery,
therapy

21

loudness & pitch disorders

associated with functional or organic causes:
mutational falsetto,
hormonal changes,
hearing loss

22

psychogenic disorders

normal laryngeal structures,
often treated with behavioral strategies,
may require psychotherapy or counseling

23

hysterical or conversion aphonia

often attributed to underlying emotional etiology
