Chapter 1 Flashcards
What is Dysphagia?
difficulty swallowing and/or difficulty moving bolus from mouth to stomach
Is dysphagia age specific?
no, ages can range from newborn to elderly
What are some etiologies of Dysphagia?
infection, structural malformations, surgery, conditions that weaken/damage muscle/nerves
What are some examples of the types of surgeries that can lead to Dysphagia?
thyroid, RLN, cervical
What are some examples of the types of conditions that weaken/damage muscle/nerves?
CVA, parkinson’s, TBI
What are some consequences of Dysphagia?
Dehydration, malnutrition, aspiration pneumonia and overall quality of life
What is the leading cause of death in Parkinson’s?
Aspiration pneumonia
What are the types of dysphagia?
Oral, pharyngeal and esophageal
although oropharyngeal can also be mentioned when its a combination of oral and pharyngeal
The types of dysphagia correlate with the __
phases of dysphagia
What are some of examples of oral dysphagia?
tongue movement, lip closure, pocketing and transport
What are some examples of pharyngeal dysphagia?
airway closure, residues, motility and UES
What are some examples of esophageal dysphagia?
motility, LES, fistula, diverticulum, HCI-reflux, ulcer
Patients who report oropharyngeal swallowing are able to describe symptoms accurately. T/F
True
Patients with esophageal disorders may be highly inaccurate in describing their symptoms. T/F
True
Literature on deglutition or swallowing falls into three categories: _
Physiology of normal swallow, changes in physiology if swallowing as a result of a variety of medical conditions and methodologies for screening/diagnosis and management of patients with dysphagia
What is diverticulum?
pockets in esophagus
What are the stages of dysphagia?
oral, pharyngeal and esophageal
Describe the oral stage.
mastication, bolus formation, and bolus transport from the oral cavity to pharynx.
This stage begins when lips close after food enters mouth.
How long does the oral stage last?
It is dependent on the bolus
Describe the pharyngeal stage.
The epiglottis inverts over the laryngeal vestibule. The larynx and hyoid bone are pulled anteriorly and superiorly to open the pharynx, relax the cricopharyngeus (UES) muscle, and assist the vocal folds in closing off the glottis. The bolus is propelled through the pharynx toward the esophagus by action of pharyngeal constrictors.
How long is the pharyngeal phase?
about 1 second
When does the pharyngeal phase begin?
when the head of the bolus gets past the posterior faucial pillar
The majority of disorders are found in what phase of the swallow?
pharyngeal
Describe the esophageal stage.
The bolus flows through the esophagus via peristaltic contractions of striated and smooth muscle along the esophageal wall. Relaxation of the LES allows bolus to flow into stomach, then closes to prevent food from coming back up
