|
|
|
Hypernasality can be characterized as
|
Increased nasal resonance perceived on vowels mostly.
|
|
|
Velopharygeal dysfunction and Velopharnygeal Inadequacy (VPI) are umbrella terms but VPI with a possible etiology of a too short velum from a previously repaired cleft is also know as
|
Velopharyngeal insufficiency
|
|
|
What is a common surgery for Velopharyngeal Insufficiency?
|
Double Z plasty
|
|
|
What is the main role of the tensor veli palatini?
|
to open the Eustacian tube in order to equalize the pressure between the middle ears and atmosphere.
|
|
|
What is the VP closure during consonants?
|
higher elevations and higher Closure
|
|
|
What is the VP closure during plosives, fricatives, and affricates (high pressure consonants)?
|
great velar height and closure
|
|
|
What is the VP closure during vowels?
|
Lower velar elevations and closure than consonants
|
|
|
What is the VP closure during high vowels?
|
Higher velar elevation and closure and contact than low vowels. Vowels adjacent to nasal consonants have les closure force.
|
|
|
What is the primary palate composed of?
|
the alveolus, premaxilla (behind the area of the incisors). This fuses at 7 weeks gestation
|
|
|
What is the secondary palate composed of?
|
Structures posterior to incisive foramen
|
|
|
What is NAM (nasoalveolar molding)?
|
It is a treatment used for cleft palates. Patients are fitted for the alveola mold (12 mm), followed by weekly fittings and adjustments. When the gap reaches 5 mm in diameter, a nasal bulb is attached. When gap is 1 mm, patient receives PE tubes
|
|
|
Describe a palatal fistulae.
|
This occurs after the palate is repaired. There is a breakdown along the surgical suture lines.
|

|
|
What is expressivity?
|
The manifestation of the traits in various degrees.

|
|
Describe Stickler.
|
It is a genetic syndrome that affects the connective tissue for the eyes, ears, and bones because of genetic failure. Affects the 12q13.11 gene
|
|
|
Describe some symptoms of Stickler.
|
Cleft palata, midface hypoplasia, myopia, sensorineural hearing loss, and epicanthal folds
|
|
|
What is Van Der Woude Syndrome and some of its symptoms?
|
It affects gene 1q32-41. May see cleft lip and/or palate, and lower lip pits.
