MBS Flashcards
MBS is a ?
also called
videofluorographic evaluation
- modified barium swallow
- cookie swallow study
- videofluoroscopic swallow study (VFSS)
Rationale: to identify ? the evaluate ? to develop an ? to implement and evaluate ? the provide ?
normal and abnormal anatomy and physiology of swallow
integrity of airway protection before during and after swallowing
effective dysphagia treatment plan for the patient
effectiveness of postures, maneuvers, bolus modification, and sensory augmentations in improving swallowing safety efficiency
recommendations regarding optimum delivery of nutrition and hydration
Why?
a radiographic study SHOULD NOT be conducted for ?
rather the major question to be answered from the radiographic study is:
sole purpose of determining whether or not the patient aspirates
what is the anatomical or physiologic cause of the patient’s apsiration
Indications:
neurological impairment
- congenital
- acquired (acute, progressive, traumatic)
structural/mechanical impairment
- head and neck cancer
- treatment of head and neck cancer via surgery, radiation therapy, and or chemotherap
Indications:
structural mechanical continued
- tracheostomy and or ventilator dependence
- vocal fold paralysis
- cervical spine repair
- craniofacial anomalies
- velopharyngeal incompetence
- pharyngeal stenosis
- pharyngeal diverticulum
Contraindications:

patient is unable
patient is unable
size of patient prevents

to cooperate or participate in instrumental exam

Limitations of videofluorographic swallowing evaluation: - -procedure only -... issues -....issues -... with potential for
time restraints due to radiation exposure
- samples swallow function
- contrast issues
- viscosity issues
- barium, unnatural food bolus / refusal

Videofluorographic swallowing evaluations: swallowing physiology and coordination: -...closure -mandibular ? -tongue ?
- oral ?
- elevation of
- bolus?
- … of bolus
lip closure
- motiona nd efficiency (lateral tongue range of motion and control )
- base retraction (strength and range of motion)
- tongue strength, range of motion and control during;
- bolus to palate
- seal against palate
- anterior to posterior propulsion of bolus
Swallowing physiology and coordination continued: -... closure -timing of -.. transport time -... and ... -pharyngeal ? (what and what ) ... movement airway ?
velopharyngeal closure
- swallow initiation
- oral and pharyngeal transport time
- range of motion and timing of velar movement
- muscle contraction (strength and degree and symmetry)
- epiglottic movement
- airway protection : supraglottic to glottic level
Swallowing Physiology and coordination continued:
- .. motion
- … mobility
- …. opening
- coordination of?
- .. of movement
hyolaryngeal motion ( vertical and anterior)
- vocal fold mobility (anterior to posterior view)
- UES opening (amplitude duration timing)
- coordination of pharyngeal structural movement during swallow
- asymmetry of movement

premature spillage into pharynx (reduced sensation)
-poor oral handling
- laryngeal elevation
- epiglottis inversion/coverage of laryngeal vestibule
- VF closure

- backflow from esophagus
