COMD 5070 Velopharyngeal Function
Questions and Correct Answers
What populations are affected by velopharyngeal problems? ✅cleft palate=structure
hearing impaired=managing velopharyngeal function
dyarthria=
What is a cleft palate? ✅when structures with in the skull and specifically the oral
cavity have failed to meet at midline, leaving a gap
How common is cleft palate? ✅1 in 750
What deficit can still occur after surgery for a cleft palate? ✅the velum itself may be
insufficiently long enough to meet with the pharyngeal wall as it constricts to give you
good velopharyngeal closure; some individuals may have residual speech problems
What kind of velopharyngeal problem would a hearing impaired person have?
✅managing velopharyngeal function because they don't have the auditory feedback
that is required to let them do this properly
If a person has marginal or extremely limited hearing what sounds won't they have the
sensitivity to hear with their own auditory feedback? ✅nasal consonants;they are
extemely low intensity sounds
What things might cause dysarthria? ✅stroke
head injury
cerebral palsy
progressive neurological disorders
How does dysarthria affect the velopharyngeal function? ✅there is a neruomuscular
deficit; the brain sends out signals to the muscles that operate the velopharyngeal port
and those signals may not be strong enough and so may not be coordinated with other
actions that are needed in the vocal tract; a functional deficit in the activity of the
velopharyngeal port resulting in elevated nasality for sounds that ought to be entirely
oral
What is affected if the velopharyngeal port is not operating appropriately? ✅serious
implications for speech intelligibility and speech quality
When there is leakage through the velopharyngeal port it allows? ✅pressure to escape
into the nasal cavity and into the nares; this causes problems for pressure consonants
where you really ought to have pressure impounded in the mouth
