The flashcards below were created by user chellen12 on FreezingBlue Flashcards. What would you like to do?


  1. Levator Veli Palatini
    major muscle for velum elevation
  2. palatopharyngeus
    closes off part of the oral cavity and pull velum down
  3. bilamiderm disk
    2 layers of tissue, how the embryo begins
  4. what happens when the facial parts do not meet correctly.
    creates cranial fissures, clefts, immorality
  5. what week does face formation take place?
    within 4 weeks
  6. what weeks does that palate form?
    8-9 weeks
  7. direction of face formation
    all comes down from midbrain or together from sides
  8. mechanically induced malformation
    factors that directly influence the development of the embryo
  9. craniofacial
    malformation of the cranium and face that effects or has the potential to effect communication
  10. cleft
    elongated opening, resulting from failure of parts to fuse. Includes: lip, hard palate, and soft palate
  11. microforms
    minimal changes is oralfacial structures
  12. examples of microforms
    cleft uvula, submucous cleft, hairline indention of the lip, minimal palatal defects
  13. a patient with a cleft uvula is life to have
    submucous cleft (palatal cleft hiding)
  14. submucous cleft
    some tissue is covering the hard palate so looks normal, but the bone and muscles have not fused
  15. indications of submucous cleft
    cleft/bifid uvula and/or high palatal vault
  16. cleft palate is related to what factor
    sex: more frequent in males
  17. cleft palate is linked to ages in males or females (dads or moms)
    males younger than 20 and older than 40
  18. international classification of clefts is based on:
    where the lack of fusion took place
  19. muscles that make up the soft palate
    levator and tensor palatine
  20. language disorder related to cleft palate and cleft lip and palate
    mild language disorder
  21. language disorder related to cleft lip
    no language disorder
  22. when to children with clefts begin to babble and speak?
    later age than non-clefted children
  23. what speech sounds are the most frequent in error?
    ones the require build up of oral pressure--intra-oral pressure
  24. what speech sounds of least affected with cleft palate?
    nasal consonants and semi-vowels
  25. what common substitution patterns (2) for cleft palate?
    • glottal stops for oral stops
    • nasal fricatives for oral fricatives
  26. percent of cleft population that has phonatory problems
    25-50%
  27. vocal problems are related to what happening with the vocal folds?
    • hyperfunction of vocal folds overdrivien to compensate for inadequate velopharyngeal function
    • push from the throat instead of the diaphragm to get louder voice
  28. soft voice syndrome
    loss of air pressure through the nasal cavity
  29. resonance
    quality of sound damped/enhanced by the cavities above the vocal folds
  30. resonance deal with...
    vowels
  31. nasal emission deals with...
    consonats
  32. how does articulation affect resonance?
    • the position of the tongue in the oral cavity
    • the tongue is held high or retracted--air gets sent through the nose and not mouth.
  33. how does the position of the mouth/lips influence resonance?
    • limited opening of the mouth/lips results in limited jaw movement
    • air mostly moves through the nasal cavity
  34. hypernasal
    • nasal cavity is open
    • occurs with abnormal coupling of the oral and nasal cavities
    • sound: "too nasal"
    • can be heard well on vowels
  35. hyponasal
    • nasal cavity is closed
    • occurs when VP port or nasal airway is partially or totally closed.
    • noticeable on consonants
  36. hypernasality occurs with what factors:
    • high vowels
    • oral opening is small
    • when valving closes too late or too early
    • high tension in head and neck
  37. nasal air emission
    • inappropriate release of air though the nasal cavity during speech
    • only occurs on consonants
    • most observable on high pressure consonants
  38. hypernasality is as ____disorder
    resonance
  39. nasal air emission is a ____ disorder
    articulation
  40. correlation phenomena
    the greater the nasal air emission, the greater the likelihood of weak or omitted consonants
  41. primary surgery
    closing the cleft
  42. secondary surgery
    refining anatomic structures for speech normalcy and cosmetic concerns
  43. after prepalatal surgery what is used to keep lines from tearing
    metal bow
  44. bilateral clefts needs pre-surgical management of what
    the maxillary, to keep from collapsing by use of an arch expander
  45. what is also done prior to bilateral ceft surgery
    premaxilla taping so tissues get used to being in place and wont tear after surgery
  46. issue with early secondary cleft repair
    potentially interfere with mid facial growth
