Dix Hallpike Maneuver vs. Epley Maneuver

Benign paroxysmal positional vertigo, more often known as BPPV, is a condition of the inner ear that is quite prevalent and is characterized by symptoms such as nausea, dizziness, and unsteadiness. The most typical cause of vertigo is BPPV, particularly in those over 65.

BPPV happens when crystals, or otoconia, that are typically found in the utricle, a component of your inner ear's vestibular system (or balance system), become dislodged and gather in one of the semi-circular canals. The displaced crystals shift as you move your head, sending the brain and the eyes the wrong signals.

The brain receives signals that indicate movement, even when the head has only shifted slightly. This will make you feel like you're moving or spinning when you do simple things like roll over in bed, get in or out of bed, or look up.

BPPV Symptoms

The activities that induce BPPV symptoms differ between individuals.

• Movements such as getting out of bed or turning over in bed frequently induce disorientation, vertigo, lightheadedness, unsteadiness, or nausea.
• When you tilt your head back to look upward, it might cause vertigo for some people.
• Symptoms are typically intermittent, disappearing for weeks or months at a time and then reappearing for extended or shorter intervals.

BPPV Effects

There are a series of fluid-filled canals within the inner ear. These canals are angled in various directions. When the head moves, the way the fluid in these tubes moves tells the brain exactly how far, how fast, and in what direction the head is moving.

The dislodgement of tiny calcium carbonate crystals (otoconia) within the canals is suggested to contribute to BPPV. Typically, the utricle and other inner ear structures contain unique reservoirs where the crystals are retained. It is hypothesized that injury or utricle degeneration might permit crystals to escape and obstruct fluid flow in the balancing system.

Dix Hallpike Maneuver vs Epley Maneuver

Both the Dix-Hallpike maneuver and the Epley maneuver are utilized to identify and manage benign paroxysmal positional vertigo (BPPV), a common cause of ear-based disorientation. The main distinctions between the two are as follows:

A diagnostic procedure called the Dix-Hallpike Maneuver is performed to diagnose BPPV and establish whether the afflicted side is on the left or the right. The patient is first positioned in an upright position with his head tilted 45° to one side, and then he is rapidly repositioned into a supine position with their head dangling off the end of the table. If benign paroxysmal positional vertigo (BPPV) is present, it may cause symptoms such as vertigo and nystagmus (involuntary eye movements). 

After the Dix - Hallpike test has identified BPPV, the Epley Maneuver is utilized to treat it. Calcium carbonate crystals that have been dislodged from the semicircular canal can be treated by moving the patient through a series of positions that are intended to relocate the crystals to a location where they will not cause discomfort. Both procedures should only be carried out by a qualified healthcare practitioner and are equally safe and effective for the diagnosis and treatment of BPPV.
