patient education and reassurance

The initial step in managing BPPV is patient education and reassurance.[35][42][43]​ This is done by explaining its non-life-threatening nature and favorable prognosis, with spontaneous remission in one third of patients at 3 weeks and the majority of patients at 6 months from onset.​[7][43][68]

Patients should be made aware that BPPV is a highly treatable condition, with the majority of episodes resolving after the administration of a single particle repositioning maneuver.[2][44][45] However, relapses and remissions can occur unpredictably in both treated and untreated patients.[48] Patients who have secondary BPPV (e.g., secondary to vestibular neuronitis) should be encouraged to return to normal physical activity to facilitate central nervous system compensation.[43]

3-position particle repositioning maneuver (PRM)

Treatment recommended for ALL patients in selected patient group

Contraindications to repositioning maneuvers include severe cervical disease, unstable cardiovascular disease, suspected vertebrobasilar disease, and high-grade carotid stenosis.[48] For those patients without contraindications, the literature describes many minor variations of the PRM technique, but the 3-position PRM variant of the Epley maneuver is recommended.[54][91] The PRM has a well documented short-term efficacy, with the majority of patients treated successfully after a single PRM attempt.[2][44][45] Postmaneuver instructions, including post-PRM postural restrictions, are not necessary.[59][60][61][62]

The procedure involves the following steps: [Figure caption and citation for the preceding image starts]: Particle-repositioning maneuver (right ear)Parnes LS, Agrawal SK, Atlas J.

Place the patient in a sitting position at the end of the examination table.

Rotate the head 45° toward the affected ear, then swiftly place the patient in a supine position with the head hanging 30° below the horizontal at the end of the examining table (Dix-Hallpike position).

Observe for primary stage nystagmus.

Maintain this position for 1-2 minutes.

The head is rotated 90° toward the opposite ear while maintaining the head hanging position.

Continue then to roll the whole patient another 90° toward the unaffected side until the head is facing 180° from the original Dix-Hallpike position. This change in position should take <3-5 seconds.

Observe for secondary-stage nystagmus. A favorable response occurs when the secondary-stage nystagmus is in the same direction as the primary-stage nystagmus, because the canalith particles would still be moving toward the utricle; an unfavorable response occurs when the nystagmus is in the opposite direction, which results when the particles regress away from the utricle toward its original position. Absence of nystagmus is not uncommon and may indicate mixed results, such as partial (incomplete) BPPV resolution.

Maintain the final position for 30-60 seconds, and then have the patient sit up. Upon sitting, there should be no vertigo or nystagmus in a successful maneuver, because the particles will have been cleared from the posterior semicircular canal back into the utricle.

For horizontal canal and anterior canal BPPV, special maneuvers exist, but these patients should be referred to a specialist center.

vestibular suppressant medication (only useful in small subset of patients)

Treatment recommended for SOME patients in selected patient group

Medication is not an effective treatment for BPPV. The use of vestibular suppressant medications such as the benzodiazepines (lorazepam, diazepam) and antihistamines (meclizine, dimenhydrinate, promethazine) is not recommended in the vast majority of BPPV cases.[35][48][49][50]

Vestibular suppressant medications are not curative and are often ineffective at symptom management given the sudden and short-lived onset of BPPV.[43][48]

Suppressants also produce unwanted adverse effects such as drowsiness. The central nervous system (CNS) suppression these drugs cause may result in disease prolongation by inhibiting central compensation for a coexisting vestibular loss: for example, in cases of BPPV secondary to vestibular neuronitis.[43][48]

There is, however, a small subpopulation of patients with prolonged autonomic dysfunction and imbalance who may benefit from vestibular suppressant medication (e.g., lorazepam or diazepam), but the CNS depressant adverse effects of these medications must be carefully weighed prior to initiating treatment.[43][48]

Rarely, a small subset of patients become extremely nauseated and emetic during a repositioning maneuver, necessitating stopping the maneuver. Such individuals may benefit from a prophylactic antiemetic (e.g., meclizine, dimenhydrinate, promethazine) prior to subsequent maneuvers.[48]

Primary options

lorazepam: 0.5 to 2 mg intravenously/intramuscularly every 4-8 hours when required; or 0.5 to 2 mg intravenously/intramuscularly as a single dose prior to repositioning maneuver

OR

diazepam: 2-10 mg orally/intravenously every 4-8 hours when required; or 2-10 mg orally/intravenously as single dose prior to repositioning maneuver

OR

meclizine: 12.5 to 25 mg orally every 4-8 hours when required, maximum 100 mg/day; or 12.5 to 25 mg orally as a single dose approximately 60 minutes prior to repositioning maneuver

OR

dimenhydrinate: 25-50 mg orally every 4-6 hours when required, maximum 400 mg/day; or 25-50 mg orally as a single dose approximately 30 minutes prior to repositioning maneuver

OR

promethazine: 12.5 to 25 mg orally/intravenously every 4-6 hours when required, maximum 100 mg/day; or 12.5 to 25 mg orally/intravenously as a single dose approximately 30-60 minutes prior to repositioning maneuver

vestibular rehabilitation exercises

Treatment recommended for SOME patients in selected patient group

Some patients may benefit from vestibular rehabilitation exercises to promote functional recovery and prevent recurrence, particularly if they are at higher risk of falls or have residual generalized dizziness after BPBPV treatment.[35][70]​ Vestibular rehabilitation consists of home exercises or a customized program delivered by a therapist. Suitable home exercises include the modified self-Epley, modified Semont, and half somersault maneuvres.[71][72][73][74]

Semont repositioning maneuver

Treatment recommended for ALL patients in selected patient group

Although the PRM and Semont maneuver share a similar mechanism and efficacy, the PRM is used preferentially by most clinicians in North America because it is more comfortable for the patient and simpler to perform, especially in overweight and older patients.[42][55][56][57][58][7] If the PRM fails after repeated sessions, then the Semont (liberatory) maneuver is the next treatment option. The procedure involves the following steps: [Figure caption and citation for the preceding image starts]: Liberatory maneuver of Semont (right ear)Parnes LS, Agrawal SK, Atlas J.

Sit the patient midway along the long side of an examination table, with their legs hanging over the edge.

Rotate the head 45° toward the unaffected side. While maintaining the head rotation, swiftly place the patient's upper body in a side-lying position on the affected side, with the head resting on the examination table and now facing upward. This may induce nystagmus and vertigo because of particle movement toward the apex of the semicircular canal. Maintain this position until the vertigo and nystagmus stop (1-2 minutes).

Move the patient rapidly through the sitting position of step 1 and into the opposite side-lying position while maintaining the same head rotation, so that the head is resting on the examination table and now facing downward. A nystagmus response in the same direction would indicate that the particles are exiting the semicircular canal. The transition from step 2 to 3 relies on inertia, and therefore it must be done very quickly. Maintain this position until the vertigo and nystagmus stop (1-2 minutes). Slowly return the patient to the sitting position of step 1.

modified and specialized treatments

Treatment recommended for ALL patients in selected patient group

If repositioning maneuvres fail after repeat surgery visits, then prompt referral to a tertiary specialist dizziness clinic is indicated.[7]

Patients with contraindications to repositioning maneuvers and those unable to tolerate repositioning maneuvers or exercises may benefit from vestibular habituation therapy under the supervision of a physical therapist.[43]

For patients with cervical spine or other issues that limit neck extension, a 30° bed tilt during the PRM can avoid the need for neck extension. It should be noted that a 30° tilt is sufficient to cause the patient to slide down the bed. Thus, although most PRMs can be easily carried out by a solo clinician, a PRM with a 30° bed tilt will require at least one assistant.

A chair that can spin and position the patient in any plane in space without the need for neck movements is available.[75]

surgery

The vast majority of BPPV cases will respond to the repositioning maneuvers or resolve spontaneously. The surgical treatment of BPPV is reserved for unrelenting, incapacitating cases where repeated attempts with repositioning maneuvers and vestibular rehabilitation exercises have failed.[78][79] Surgical treatment may also be considered for patients who respond to PRMs but have unremitting recurrences soon after, to the extent that they are eager for a definitive solution rather than repeated PRMs. Less than 1% of BPPV patients will ever require surgery, but because BPPV is so common, that number of surgical candidates is not negligible.[80]

Prior to surgery, all other diagnoses must be excluded and imaging of the posterior fossa is a prerequisite. There are two surgical procedures for BPPV: singular neurectomy and posterior canal occlusion. Posterior canal occlusion surgery is the recommended procedure and has been shown to be a highly efficacious, safe, and reproducible technique in numerous studies.[78][80][81][82][83][84][85][86] The technique is based on the premise that obstruction of the posterior semicircular canal lumen prevents endolymphatic flow and thus renders the cupula immobile.[79][87]
