Video: Hands-on Help: Barry Snow, Neurologist Objective: To compare the efficacy and recurrence rates of modified Epley maneuver, modified Semont maneuver and Brandt-Daroff maneuver in patients with posterior canal benign paroxysmal positional vertigo (PC-BPPV). In the video below, Barry Snow, a neurologist at Auckland City Hospital, discusses a flow chart he has developed to help diagnose and determine the best treatment for vertigo, and demonstrates the Dix-Hallpike test for benign paroxysmal positional vertigo (BPPV). It isn't painful but may bring on an attack of vertigo and possibly nausea and vomiting. BPPV with the most common variant (crystals in the posterior SCC) can be treated successfully with no tests, pills, surgery or special equipment by using the Epley maneuver. This test is called the Dix-Hallpike test and can be performed in the health professional’s rooms. It involves a health professional experienced in the treatment of benign paroxysmal positional vertigo (BPPV) carrying out a series of body and head manoeuvers to look for the ‘jumping’ of the eyes that's seen in people with BPPV. The main diagnostic test is called the Dix-Hallpike test. Your doctor will also examine your ears and eyes, check your balance and your nerves. No blood test is needed to diagnose BPPV, but your doctor may order some blood tests or further tests to rule out other conditions. They will also find out whether you have other symptoms such as hearing loss or ear fullness to rule out another diagnosis. Your doctor will ask you about your symptoms and their relation to any head movements. You are also at higher risk of BPPV if you are a woman, suffer from a head or ear injury, or have had an infection in your inner ear. It is not clear why some people have these loose calcium crystals, but it is thought to be related to increasing age, so BPPV is more common in people over the age of 40. Your brain gets confused between these extra nerve signals and the normal nerve signals sent from your unaffected ear, resulting in vertigo. These nerve signals tell your brain the movement and position of your head.īPPV occurs when there are loose calcium crystals in the fluid of the semicircular canals of one ear, causing extra nerve signals or wrong signals to be sent to your brain. Your semicircular canals contain fluids that send signals to your brain when your head moves.

The cochlea helps with hearing, whereas the semicircular canals help with balancing and posture. Your inner ear includes the cochlea and semicircular canals. BPPV is a condition that affects your inner ear. The advantage of deep head hanging maneuvers is that they can be effectively performed without knowledge of the side involved.Each of your ears has 3 parts: the outer ear, the middle ear and the inner ear. Anterior canal BPPV is rare and generally short-lived, but there is weak evidence that deep head hanging and a variety of eponymous maneuvers may hasten recovery. For horizontal canal BPPV, the Gufoni maneuver is easier to perform compared to the BBQ roll, as it requires that the clinician only identify the side of weaker nystagmus (regardless of whether it's geotropic or apogeotropic) and not necessarily the side involved. Treating posterior canal BPPV with Epley or Semont manuevers is comparable as far as efficacy and the ease with which maneuvers are performed. The Epley maneuver or repositioning maneuver is a maneuver used by medical professionals to treat one common cause of vertigo, benign paroxysmal positional vertigo (BPPV) needs update of the posterior or anterior canals of the ear. Since the therapeutic efficacy amongst maneuvers for each canal is comparable, the choice of treatment is generally based on clinician preference, complexity of the maneuvers themselves, poor treatment response to specific maneuvers, and musculoskeletal considerations such as arthritic changes and range of motion of the cervical spine. There is good evidence to support treatment of posterior canal BPPV with Epley or Semont maneuvers and horizontal canal BPPV with Gufoni maneuvers or BBQ roll (also known as Lempert 360 roll or log roll) and weaker evidence for head hanging maneuvers in the least common anterior canal variant. Surgery has a very minor role in the management of BPPV, and although medications may transiently ameliorate symptoms, they do not treat the underlying process. Repositioning maneuvers are highly effective in treating BPPV, inexpensive, and easy to apply. There are few conditions in neurology that are diagnosed with such ease and certainty as benign paroxysmal positional vertigo (BPPV).
