Acoustic technique for determining timing of velopharyngeal closure in swallowing

Dysphagia, 1990
A 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, 1971
To 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, 1974
Velopharyngeal 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

2015
The 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, 1984
Computerized 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, 2000
This 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, 2014
Sir, 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), 2019
Cleft 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 ...

A Respirometric Technique for Evaluating Velopharyngeal Closure in Children

Journal of Speech, Language, and Hearing Research, 1982
Respirometric quotients, indices of velopharyngeal closure, were determined from oral and nasal air volumes measured separately but simultaneously. Ten children aged 6–10 years were the subjects. The quotients were significantly lower for speech stimuli involving nasal sounds than for those involving nonnasal sounds.

Preoperative Velopharyngeal Morphology in Older Cleft Palate Patients With Postoperative Velopharyngeal Closure Versus Velopharyngeal Insufficiency

Journal of Craniofacial Surgery, 2013
The purpose of this study was to investigate the preoperative morphology of velopharyngeal structures in older patients with cleft palate and to evaluate which structure(s) could distinguish velopharyngeal function. The investigators implemented a retrospective study and 66 patients whose palate was repaired by 1 surgeon with the same technique were ...
