is defined as the act of swallowing, resulting from a complex and dynamic neuromotor mechanism, which aims to transport the food bolus from the mouth to the stomach effectively.
Well-proportioned tongue thrust which is repeated during deglutition
in the maxilla and mandible helps in their forward and lateral growth.
All patients in the jejunum and gastric tube groups had normal deglutition
after 6 months.
The maxillofacial and oral region has structures that are static and dynamic as well as special organs responsible for special functions such as mastication, deglutition
, and speech.
Maintaining proper laryngopharyngeal sensation, re-creating a functional neoglottic valve and an adequate airway and enhancing physiological coordination during deglutition
are crucial for successful rehabilitation of swallowing.
It has been reported in all age groups and may be due to anatomical or functioning abnormality in deglutition
, such as Zenker's diverticulum, cleft palate, hiatal hernia, achalasia, or other neuromuscular diseases, affecting pharyngeal motility or the cough reflex [2, 6].
Their etiology remains obscure, although hydramnion has been occasionally associated with fetal cranio-facial deformities, suggesting a potential role of fetal deglutition
in the regulation of amniotic fluid volumes.
According to Rahn and Heartwell, the immediate complete denture should satisfy the following requirements: (1) Compatibility with the surrounding oral environment, (2) restoration of masticatory efficiency within limits, (3) harmony with the functions of speech, respiration, and deglutition
, (4) esthetic acceptability, and (5) preservation of the remaining hard and soft tissue support.
This complex mechanism of pharyngeal phase of deglutition
is controlled by the interneuronal circuit of the medullary swallow center.
Sherman, "Subthalamic nucleus deep brain stimulation improves deglutition
in Parkinson's disease," Movement Disorders, vol.
The patient's phonation, chewing, deglutition
, and aesthetic improved.
Glossopharyngeusandhypoglossus nerves can be impressed so that deglutition
is impairment and microaspiration or aspiration pneumonia can occur.
