lesson 6 Flashcards
Radiographic examination of the pharynx and upper
esophagus during active deglutition
PHARYNGOGRAPHY
PHARYNGOGRAPHY INDICATIONS:
- Abnormalities in
deglutition.
PHARYNGOGRAPHY CONTRAINDICATIONS:
- Known allergies to
C.M.
PHARYNGOGRAPHY TYPE OF C.M AND ROUTE OF ADMINISTRATION
- Thick creamy Barium sulfate held by the tongue
administered via swallowing.
PHARYNGOGRAPHY
PROCEDURE/PROJECTIONS:
- Hold C.M. in the mouth until signaled to swallow.
- Attempt mucosal study by restricting the patient from swallowing again.
- Take mucosal study using Modified Valsalva Maneuver for double contrast
delineation.
Radiographic examination of laryngeal structures using C.M
LARYNGOGRAPHY
LARYNGOGRAPHY TYPE OF C.M AND ROUTE OF ADMINISTRATION
- Negative C.M. (To demonstrate air containing
laryngeal structures) - Positive C.M. (5 hrs NPO) – 10-15 ml of Dionosil
LARYNGOGRAPHY
PROCEDURE/PROJECTIONS:
- Have the patient position in Seated Upright/Supine AP and Lateral and used soft
tissue technique during exposure. - Head is extended to prevent superimposition of mandible to larynx during
AP projection. - If negative and positive C.M. are used the
procedure is made during Respiratory Stress
Maneuvers.
FOR TOMOLARYNGOGRAPHY (Tomographic
study of laryngeal structures):
- Made during quiet inspiration and expiration phonation.
- Exposure made using arc of 40-50 degrees.
CONTRAST STUDY OF THYROID GLANDS
PROCEDURE/PROJECTIONS:
- Position the patient in lateral making the
thyroid mass tangent to the IR. - Rotate shoulders posteriorly in LATERAL
POSITION to demonstrate intrathoracic
extension of goiter. - Obtain OBLIQUE views of the neck to
demonstrate Nodular enlargement.
For Vocal cords and cleft palate
PHONATION OF VOWELS
For distention of subglottic larynx and trachea with air.
VALSALVA MANEUVER
For distention of supraglottic larynx and laryngopharynx with air
MODIFIED VALSALVA MANEUVER
HEIGHT OF ACT OF SWALLOWING OF 1 TBSP. OF CREAMY C.M
For Pharyngeal structures
ACT OF SWALLOWING WITH TUFT/PLEDGET OF COTTON SATURATED
IN C.M
For non-opaque foreign bodies in pharynx and upper esophagus.
