Schluckmuster

Schluckmuster is a term used in medical and speech-language pathology contexts to describe the characteristic sequence and coordination of the muscles and structures involved in deglutition. It encompasses the phases of swallowing and the timing of movements of the tongue, the larynx, the pharynx, and the esophagus. In clinical practice, the concept is applied to both adults and children, and in pediatrics it is often discussed alongside the coordination of sucking, swallowing, and breathing.

A typical, healthy Schluckmuster includes distinct phases: the oral preparatory and oral transit phase, followed by a pharyngeal phase in which the bolus is propelled toward the esophagus while airway protection is maintained, and finally esophageal peristalsis. Proper timing and coordination are essential to prevent residue and aspiration, and to ensure efficient transfer of the bolus.

Abnormal Schluckmuster can indicate dysphagia or other swallowing disorders. Variants include delayed initiation of the swallow, reduced tongue propulsion, insufficient airway protection, pharyngeal constriction deficits, or residue in the valleculae or pyriform sinuses. In infants and young children, poor coordination between sucking, swallowing, and breathing can lead to coughing, choking, or insufficient weight gain.

Assessment typically combines clinical bedside evaluation with instrumental methods such as videofluoroscopic swallow study (VFSS) or fiberoptic endoscopic evaluation of swallowing (FEES). Treatment depends on the underlying cause and may involve speech-language pathology therapy, compensatory strategies, postural adjustments, and dietary modifications to improve safety and efficiency of swallowing.
