cleft palate Flashcards
what causes hypo nasality?
- upper airway obstruction due to adenoid hypertrophy or nasal blockage (pg.339)
what causes cul-de sac resonance?
caused by enlarged tonsils, which blocks the entrance to the oral cavity causing pharyngeal cul-de-sca- resonance
(pg.339)
Clinician decides to do nasopharyngoscopy, in which the nasopharyngoscope is passed through the
middle meatus and back to the area of velopharyngeal closure. What will this procedure
enable the clinician to observe?
The child’s posterior and lateral pharyngeal walls, as well as the nasal aspect of the velum
and the adenoid pad as the child produces sentences
What speech characteristics could you expect to find with a partial submucous cleft palate accompanied by a bifid uvula.?
- Hypernasality
- decreased intraoral breath pressure
- difficulties with fricatives, affricates, and plosives
Eustachian tube dysfunction in children with cleft is most related to lack of contraction of the ________________.
tensor veli palatini muscle.
Are cleft lips more often unilateral or bilateral?
unilateral on left side

Assessment:
What allows examiner to view posterior and lateral pharyngeal walls as well as nasal aspect of velum and adenoid pad as client produces sentences?
Nasopharyngoscopy
Assessment:
What can observe movements of soft palate, lateral pharyngeal wall, posterior pharyngeal walls and tongue as client produces CV’s, voiced and voiceless fricatives and selected phrases?
Videofluoroscopic
Assessment:
What gives ratios of inhalation and exhalation?
Oral manometer
What does a ratio of 1.0 on an oral manometer suggest?
adequate velopharyngeal closure
What does a ratio of less than 1.0 on an oral manometer suggest?
VPI, reduced intelligibility, hypernasality
