Reflexogenic Areas for Velopharyngeal Closure in Rabbits
Dysphagia, 1998Responsive 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 ...

Measurement of Velopharyngeal Closure Force during Vowel Production
Cleft Palate-Craniofacial Journal, 1994The 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.

Acoustic technique for determining timing of velopharyngeal closure in swallowing
Dysphagia, 1990A pure tone sound source was introduced at a nostril and monitored by a miniature accelerometer on the throat. During velopharyngeal closure in a swallow, the pure tone component in the accelerometer signal was attenuated. Throat accelerometer recordings were made simultaneously with videofluoroscopy of a modified barium swallow in adults with normal ...

Radiological evaluation of velopharyngeal closure.
JAMA, 1971To the Editor.— We wish to add some remarks to the reports ( 216 :2075, 1971) of papers presented by Hogan and Zaborsky at the plastic surgery meeting in Williamsburg, Va, concerned with the success and failure of pharyngeal flaps in eliminating nasality in patients with cleft palate.

Variations in Velopharyngeal Closure Assessed by Endoscopy
Journal of Speech and Hearing Disorders, 1974Velopharyngeal closure may be observed directly with a laryngeal telescope 6 mm in diameter. The speech sample used during the endoscopic examination should include several repetitions of a plosive consonant to insure sustained closure. Thirty-four normal subjects were observed, and the percentage of occurrence in four categories of velar and lateral ...

Anatomy and Physiology of Velopharyngeal Closure and Insufficiency
2015The velopharynx is a complex structure that is responsible for separation of the oral and nasal cavities during speech production and swallowing. Incompetence of this mechanism can lead to hypernasality, with nasal air emission and incomprehensible speech, as well as nasopharyngeal regurgitation. There can be a significant social stigma associated with

Evaluation of Velopharyngeal Closure by CT Scan and Endoscopy
Plastic and Reconstructive Surgery, 1984Computerized tomography (CT) and endoscopy were used for the objective evaluation of velopharyngeal closure. In 19 patients with cleft palates and 9 normal subjects, CT scans of the velopharynx were made both at rest and during vowel phonation with a scanning time of 3.0 seconds and slicing width of 3 mm.

Induced Fatigue Effects on Velopharyngeal Closure Force
Journal of Speech, Language, and Hearing Research, 2000This investigation studied the effects of induced velopharyngeal fatigue in speakers with normal mechanisms. Five adult female and 5 adult male subjects were used. A force sensing bulb was placed in the velopharynx to measure velopharyngeal closure force and intramuscular electrodes were inserted in the levator veli palatini muscle to sample muscle ...

Evaluating velopharyngeal closure with real-time MRI
Pediatric Radiology, 2014Sir, It was with great interest that we read the article titled “Feasibility study to assess clinical applications of 3T cine MRI coupled with synchronous audio recording during speech in evaluation of velopharyngeal insufficiency in children” by Sagar and Nimkin [1].

Investigating Velopharyngeal Closure Force with Linear Regression
2019 IEEE International Conference on Bioinformatics and Biomedicine (BIBM), 2019Cleft palate is a common birth defect worldwide. Children diagnosed with this abnormality face difficulties during feeding, hearing, and especially speech. Although surgical methods exist to repair cleft palate, subsequent corrective surgeries are often necessary since children are unable to gain full speech capabilities due to velopharyngeal ...
