Anatomy of the semicircular canals.
Epley maneuver. Move the patient back in the gurney such that when he lies down, his or her head will hang over the edge of the gurney. Emphasize to the patient to keep his or her eyes open during each position so that nystagmus can be observed. Lower the guardrails of the gurney on the opposite side from which the patient's head is turned.
Epley maneuver. Turn the patient's head 45° to the side that had the most prominent symptoms during the Hallpike test. In this example, the patient's head is turned 45° to the left. With both hands holding the patient's head, gently lay the patient down in the supine position with the head hanging over the edge of the bed. Note: Each maneuver does not need to be performed rapidly. The Epley maneuver is positional, not positioning.
Epley maneuver. The patient's head should be at 45° and hanging off the edge of the bed. Observe the patient's eyes and look for torsional nystagmus. Keep the patient in this position for at least 30 seconds or until the nystagmus or symptoms resolve.
Epley maneuver. Because the patient's head will be turned 90° in the other direction, the physician needs to move to the head of the gurney and regrip the patient's head so that the fingers are pointing toward the patient's feet.
Epley maneuver. Turn the patient's head 90° in the opposite direction (in this case, the patient's head is now facing to the right). Again, observe for nystagmus and hold this position for at least 30 seconds or until nystagmus or symptoms resolve.
Epley maneuver. Close-up view of step shown in Media file 6.
Epley maneuver. Ask the patient to turn onto his or her shoulder.
Epley maneuver. Guide the patient's head down so that he or she is looking at the ground. Again, wait for at least 30 seconds.
Epley maneuver. Close-up of view shown in Media file 9.
Epley maneuver. The patient's head needs to be regripped again. Then, the patient needs to sit up with the legs hanging over the side of the gurney (which is why the guardrails need to be lowered before the start of the procedure).
Epley maneuver. The patient is now sitting upright.
Epley maneuver. Move the patient's head slightly forward. This completes the Epley maneuver. The maneuver may be performed multiple times.
Hallpike test. In this example, the right posterior semicircular canal is being tested. Note that the head extends over the edge of the gurney. The thumb can be used to help keep the eyelids open since noting the direction of the nystagmus is important.
Epley maneuver. In this example, the left posterior semicircular canal is being treated. In this clip, the maneuvers are performed quickly. In a real patient, each position should be held for at least 30 seconds or until resolution of the nystagmus and vertigo.
Semont maneuver. Generally reserved for the cupulolithiasis form of benign positional vertigo, in which the otoliths are attached to the cupula of the semicircular canal. This maneuver has to be performed rapidly to be effective, and it is not recommended in elderly persons. In this example, the right posterior semicircular canal is being treated.
Bar-b-que maneuver. This maneuver is used to treat horizontal canal benign positional vertigo. In this example, the right horizontal canal is being treated. Each position should be held at least 20-30 seconds.
