Talmud ; Scott C. Talmud 1 ; Scott C. Vertigo can be a challenging complaint to evaluate and treat. It can arise from a slew of vastly different pathophysiologies, with acuity ranging from minimally consequential to catastrophic.
The maneuver, when properly employed, can identify a common, benign cause of vertigo, which can then be treated with bedside maneuvers, often providing instant relief to patients.
This disease process is thought to be caused by free-floating debris often in the form of a calcium carbonate stones, termed otoliths in the semicircular canals of the inner ear. Three canals make up this system, each forming a loop filled with endolymph and lined with hair cells.
During normal rotational movement of the head, the fluid endolymph remains relatively motionless while the canals and the hair cells move. The hair cells are mechanically pushed by the resistance of the endolymph, opening mechanically gated ion channels that trigger an action potential indicating rotational movement.
Each of the three canals is oriented slightly differently, with the anterior and posterior canals in the vertical plane, set to detect movement in the sagittal and coronal planes, respectively, and the lateral canal 30 degrees off from the maaneuver plane, detecting movement to the left or right in hallpile horizontal plane.
This results in the sensation of movement and nystagmus characteristic of vertigo in brief paroxysms with positional changes of the head. The patient is positioned recumbent with the head back and toward the affected ear, causing the otolith to progress superiorly along the natural course of the canal.
Typically, after a five to second delay, this will cause vertigo and rotary or up-beating nystagmus, which will resolve within 60 seconds.
These patients experience vertigo in brief episodes lasting less than one minute with changes of head position and return maneuber total normalcy between episodes. Light-headedness or a sensation of nausea might last longer than one minute, but if the sensation of movement persists for more than one-minute alternative diagnoses must be considered. Dizziness is a common complaint, and serious causes must be considered and excluded first.
Non-paroxysmal vertigo is more likely to be caused by a vestibular syndrome or central etiology, such as brain stem stroke. Any neurological deficit, especially truncal ataxia, should generate concern for a central cause and trigger further workup.
The Dix-Hallpike maneuver should be avoided in a patient with neck pathology, in whom the movements involved could be dangerous to the patient.
Cervical instability, vascular problems like vertebrobasilar insufficiency and carotid sinus syncope, acute neck trauma and cervical disc prolapse are absolute contraindications. In patients without an absolute contraindication, one paper suggests briefly assessing neck rotation and extension before attempting the maneuver to see if these positions can be comfortably maintained for thirty seconds.
All that is required for this test is a bed that can recline to horizontal, but certain equipment can be helpful, if available. Frenzel goggles can be useful to magnify the movements of the eyes.
A mat table can be useful for elevating the shoulders and keeping the patient closer to the ground and thus, safer. Video ENG equipment can be used by advanced practitioners to better monitor eye movements during this maneuver. Consider an antiemetic before implementing the test.
The patient begins sitting up, and their head is oriented 45 degrees toward the ear to be tested. The clinician then lies the patient down quickly with their head past the end of the bed and hallpiike their neck 20 degrees below the manehver, maintaining the initial rotation of the head. The clinician then watches the patient’s eyes for torsional and up-beating nystagmus, which should start after a brief delay and persist for no more than one minute. This would indicate a positive test. If the test is negative but clinical suspicion remains high, the patient should be given a chance to recover for at least one minute, and then testing of the other ear can be undertaken.
Lateral canal pathology may not be detected by this method, and a supine roll test may be done if this is suspected. The exclusion of dangerous etiologies of vertigo should be the clinician’s primary concern, requiring excellent history and physical examination skills.
While there is a high rate of recurrence and this is not always effective, relieving the symptoms of our patients in this way is highly desirable, and patients can be given instructions on how to do this at home for recurrences.
