Definition
- A test which uses differences in temperature to diagnose ear nerve damage.

- Positive = meniere's dz

- This test stimulates the inner ear and nearby nerves by delivering cold and warm water to the ear canal at different times.

- cold water enters the ear, it should cause nystagmus. The eyes should move away from the cold water and slowly back.

- Warm water is placed into the ear. The eyes should now move towards the warm water then slowly away.

- electrodes, placed around the eyes, detect the movements. A computer records all the results.

Term
modified Epley maneuver
Definition
- modified Epley maneuver. (for BPV) -- Turns pt's head 45 degrees horizontally toward the affected ear. Hold the pt's arms for support. Tilt the pt backward to a horizontal position with your head kept in place at a 45-degree turn, hanging. An attack of vertigo is likely as the debris moves toward the apex of the canal. Hold in this position until the vertigo stops, usually within a minute. Turn the pt's head 90 degrees toward the unaffected ear. Roll the pt to the side of the unaffected ear, so they are now looking at the floor. The debris should move in the canal again, possibly provoking another attack of vertigo. You should remain in this position until the vertigo subsides, usually within a minute. Help pt back to a seated position. Then tilt the pt's head down 30 degrees, which allows the debris to fall into the utricle of the canal where it will not cause vertigo.[image]
Term
Semont maneuver
Definition
- Semont maneuver (for BPV) --Turn head 45 degrees horizontally toward the unaffected ear.Tilts pt 105 degrees so pt is lying on the side of the affected ear with your head hanging and your nose pointed upward. You remain in this position for 3 minutes. The debris should move to the apex of the canal. Then moves the pt quickly through the seated position, holding your head in place, until you are lying on the side of the affected ear with your nose pointed to the ground. You remain in this position for 3 minutes. The debris should move toward the exit of the canal. Then slowly move the pt back to the seated position. The debris should fall into the utricle of the canal, where it will not cause vertigo.[image]
