Effects of Respiration on Soft Palate Movement in Feeding.
Summary of "Effects of Respiration on Soft Palate Movement in Feeding."
Cyclic soft palate elevation is temporally associated with masticatory jaw movement. However, the soft palate is normally lowered during nasal breathing to maintain retropalatal airway patency. We tested the hypothesis that the frequency and amplitude of soft palate elevation associated with mastication would be reduced during inspiration. Movements of radiopaque soft palate markers were recorded by videofluorography while 11 healthy volunteers ate solid foods. Breathing was monitored with plethysmography. Masticatory sequences were divided into processing and stage II transport cycles (food transport to the oropharynx before swallowing). In food processing, palatal elevation was less frequent and its displacement was smaller during inspiration than expiration. In stage II transport, the soft palate was elevated less frequently during inspiration than expiration. These findings suggest that masticatory soft palate movement is diminished during inspiration. The control of breathing appears to have a significant effect on soft palate elevation in mastication.

Medical and Biotech [MESH] Definitions
The structure that forms the roof of the mouth. It consists of the anterior hard palate (PALATE, HARD) and the posterior soft palate (PALATE, SOFT).
Tumors or cancer of the PALATE, including those of the hard palate, soft palate and UVULA.
Congenital fissure of the soft and/or hard palate, due to faulty fusion.
A movable fold suspended from the posterior border of the hard palate. The uvula hangs from the middle of the lower border.
Failure of the SOFT PALATE to reach the posterior pharyngeal wall to close the opening between the oral and nasal cavities. Incomplete velopharyngeal closure is primarily related to surgeries (ADENOIDECTOMY; CLEFT PALATE) or an incompetent PALATOPHARYNGEAL SPHINCTER. It is characterized by hypernasal speech.
This study reconstructed a three dimensional fluid/structure interaction (FSI) model to investigate the compliance of human soft palate during calm respiration. Magnetic resonance imaging scans of a h...
We found a case of salivary mucocele which originated in the minor salivary gland (palatine gland) of the soft palate in a dog. At first admission, the soft palate swelled remarkably. Computed tomogra...
The tissue in the palatal region can be divided into the hard and the soft palates, each having a specialized function such as occlusion, speech, or swallowing. Therefore, an understanding of the mech...
Objective: To find an anatomical measurement of the cleft palate (or a calculated parameter) that predicts the occurrence of velopharyngeal insufficiency (VPI) after palatal cleft repair. Study Design...
Abstract Objective: To study changes in cleft size and maxillary arch dimensions from infancy to 5 years and evaluate these changes in relation to performed surgical procedures. Design: Retrospect...
In this study, we want to see how feeding affects breathing in small premature babies. Using a special feeding tube in the stomach, we can measure how the diaphragm (a large breathing musc...
The aim of this study is to determine the postoperative course including effects on the quality of life following soft palate surgery with radiofrequency knife (RAUP).
The purpose of the study is to compare the effectiveness of soft palatal implants with placebo and continuous positive airway pressure treatment in obstructive sleep apnea.
The overall research problem is that cerebral palsy and accompanying sensory neuro-impairments is a major epidemiological problem for some pre, near, and term age infants. Both infant and...
This trial is a randomised controlled trial with a parallel design taking place in centres across the UK, Scandinavia and Brazil. 650 infants with a diagnosis of isolated cleft palate who...
