Hypernasality in the Presence of “Adequate” Velopharyngeal Closure

Cleft Palate-Craniofacial Journal, 1993
In some instances, hypernasality occurs despite an instrumental assessment of “adequate” velopharyngeal closure. The pressure-flow technique was used to assess the timing characteristics associated with velopharyngeal closure in 11 such subjects. The group's performance was compared to the aerodynamic characteristics of two other subject groups.

Velopharyngeal Closure and the Longus Capitis Muscle

Acta Oto-Laryngologica, 1996
The dynamic mechanism of velopharyngeal function not only in normal individuals but also in patients with velopharyngeal insufficiency, which is mainly related to cleft palate, has been the subject of considerable interest and controversy. Recently, in order to clarify velopharyngeal movement in the valvular action on phonation we examined dynamic MR ...

Reflexogenic Areas for Velopharyngeal Closure in Rabbits

Dysphagia, 1998
Responsive areas for velopharyngeal closure were examined by recording diaphragmatic and superior pharyngeal constrictor activities of anesthetized rabbits. Pressure stimulation was applied with a cotton applicator to the mucosae of three pharyngeal areas: the anterior (palatal) and posterior walls of the nasopharynx and the posterior wall of the ...

Instrumental Assessment of Velopharyngeal Closure for Speech

Seminars in Speech and Language, 2011
The presence of a palatal cleft at birth should not prevent good speech production in most children provided they have (1) appropriate surgical intervention to close the palate at or around the child's first birthday, (2) careful monitoring of speech development throughout childhood, (3) speech therapy when needed, and (4) secondary surgical or speech ...

Measurement of Velopharyngeal Closure Force during Vowel Production

Cleft Palate-Craniofacial Journal, 1994
The purposes of this study were to (a) design and test a new velopharyngeal closure force sensing bulb, and (b) use the closure force bulb to gather additional information on the variations in closure force associated with different vowels. The closure force sensing bulb possessed a flat frequency response to 30 Hz.
