Card Set Information
Voice disorder children elderly
voice disorders in children and elderly
Infant vocal tract?
velum & epiglottis in close proximity
VFs have not developed a VL, there are no layers, thick cover, e/ more vasularity
Arytenoids are disproportinately large
laryngeal position is high
hyoid bone and thyroid cartilage are contiguous
Common voice disorders in children?
Fund. freq high at infancy (55 Hz) but slowly lowers as ages
children may have greater jitter, less vocal control
Ps higher than for adults, lower mean airflow rates
max phonation times are lower until puberty
___? soft cartilages, collapse of structures into airway
surgery if airway is obstructed
w/o surgery it will resolve on its own
usually detected at birth
__? narrowing in trachea
if it involves cartilage and airway is obstructed, surgery is necessary
if it involves soft tissue only, it may resolve spontaneously
Vocal Fold Papilloma
Signs of congenital anomalies?
___: most common acquired disorder in children- accounts for 50% of acquired disorders?
__: trauma to RLN
Tx of nodules in children?
conservative - no surgery
involve family, teacher
ID and modify causal behaviors
minimize excessive inappropriate vocal behaviors
trend- adults who had nodules as children seem to have a higher incidence of voice problems
VF characteristics in persons ___?
> 65 y/o
blood flow decreases
lamina propria thickens
: less elastin and collagen, more fibrotic tissue
atrophy of muscle
decreased neuronal firing rates
varies e/ gender
pitch higher in males, lower in females
decr freq and intensity ranges
greater Fo variability
decr intensity variability
slower speaking rate
smaller vital capacity
decr lung pressure
greater peak airflow and greater air leakage
greater open quotient
bowing, incomplete closure, posterior gap
atrophy and thinning of VFs
Decr mucosal wave and amplitude of vibration
incr VF stiffness
most common disorders?
laryngeal cancer (men)
VF paralysis (women)
Nodules and Polyps
many voice problems in elderly are not caused by aging (4%) but by disease
