Management of Vestibular Disorders

Diagnostic Approach

The American Academy of Otolaryngology-Head and Neck Surgery recommends determining the specific type of vestibular disorder through careful history and diagnostic maneuvers, as management differs significantly based on etiology 1
For suspected BPPV, the American Academy of Otolaryngology-Head and Neck Surgery suggests performing the Dix-Hallpike maneuver to diagnose posterior canal BPPV (vertigo with torsional, upbeating nystagmus) 2
If Dix-Hallpike is negative but BPPV is still suspected, the American Academy of Otolaryngology-Head and Neck Surgery recommends performing the supine roll test to assess for lateral semicircular canal BPPV 2
The American Academy of Otolaryngology-Head and Neck Surgery advises differentiating vestibular disorders from other causes of imbalance, dizziness, and vertigo including central disorders (stroke, migraine), other neurotologic conditions (cerebellopontine angle tumors), and systemic conditions 3
The American Academy of Otolaryngology-Head and Neck Surgery recommends avoiding unnecessary radiographic imaging in patients who meet diagnostic criteria for BPPV unless additional signs/symptoms inconsistent with BPPV are present 2
Similarly, the American Academy of Otolaryngology-Head and Neck Surgery suggests avoiding routine vestibular testing in patients with clear BPPV unless additional vestibular signs/symptoms warrant further investigation 4

The American Academy of Otolaryngology-Head and Neck Surgery recommends canalith repositioning procedures as first-line treatment for BPPV 4
For posterior canal BPPV, the American Academy of Otolaryngology-Head and Neck Surgery suggests performing the canalith repositioning maneuver (Epley maneuver) 4
For lateral canal BPPV, the American Academy of Otolaryngology-Head and Neck Surgery recommends performing the roll maneuver (Lempert maneuver or barbecue roll) 5
The American Academy of Otolaryngology-Head and Neck Surgery advises that postprocedural restrictions are not necessary after canalith repositioning 2
The American Academy of Otolaryngology-Head and Neck Surgery recommends offering vestibular rehabilitation exercises either self-administered or with a clinician 6
The American Academy of Otolaryngology-Head and Neck Surgery suggests including habituation exercises, adaptation exercises for gaze stabilization, and balance training 5

The American Academy of Otolaryngology-Head and Neck Surgery recommends using vestibular suppressants (antihistamines, benzodiazepines) only for short-term symptomatic relief during acute vertigo attacks 7
The American Academy of Otolaryngology-Head and Neck Surgery advises being aware that centrally acting anticholinergic drugs (scopolamine, atropine) can suppress acute vertigo but have significant side effects including blurred vision, dry mouth, urinary retention, and sedation 7
The American Academy of Otolaryngology-Head and Neck Surgery recommends that all benzodiazepines carry significant risk for drug dependence and should be used cautiously 7

The American Academy of Otolaryngology-Head and Neck Surgery recommends assessing for modifying factors including impaired mobility/balance, central nervous system disorders, lack of home support, and increased fall risk 8
The American Academy of Otolaryngology-Head and Neck Surgery suggests implementing fall prevention strategies as patients with vestibular disorders have significantly higher fall risk 9
The American Academy of Otolaryngology-Head and Neck Surgery advises screening for comorbidities that may complicate management, including sleep apnea in patients with increased vertigo 7
The American Academy of Otolaryngology-Head and Neck Surgery recommends considering the impact of traumatic brain injury, as post-traumatic BPPV may be more refractory to treatment and may require repeated physical treatments 8

The American Academy of Otolaryngology-Head and Neck Surgery recommends educating patients about their specific vestibular disorder, treatment options, and risk of recurrence 9
The American Academy of Otolaryngology-Head and Neck Surgery suggests providing information about safety concerns, particularly fall risk 9
The American Academy of Otolaryngology-Head and Neck Surgery advises reassessing patients within one month after initial treatment to document resolution or persistence of symptoms 2
The American Academy of Otolaryngology-Head and Neck Surgery recommends evaluating for unresolved vestibular disorders or underlying peripheral/central nervous system disorders for persistent symptoms 2

The American Academy of Otolaryngology-Head and Neck Surgery recommends providing written instructions for home exercise programs 5
The American Academy of Otolaryngology-Head and Neck Surgery suggests educating patients and caregivers about potential disease recurrence and when to seek follow-up care 9
The American Academy of Otolaryngology-Head and Neck Surgery advises considering home safety assessment for patients with persistent balance issues 8

Migraine occurs in 34% of BPPV patients compared to only 10% in non-dizzy control populations, representing a more than 3-fold increased prevalence, according to the American Academy of Otolaryngology-Head and Neck Surgery 10
The association between migraine and BPPV is bidirectional—BPPV is more common in migraine patients, and migraine is more common in BPPV patients, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 11
Clinicians should routinely assess all BPPV patients for migraine history because it fundamentally modifies management and treatment outcomes, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 10, 12

Obtain detailed migraine history in all BPPV patients, including headache characteristics, frequency, associated symptoms, and current migraine treatments, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 10, 12
Avoid routine imaging unless atypical features are present, according to the American Academy of Otolaryngology-Head and Neck Surgery 13, 14

Implement fall risk screening using CDC-recommended questions, as advised by the American Academy of Otolaryngology-Head and Neck Surgery 15, 10, 12
Elderly patients with BPPV are at 12-fold increased fall risk, and comorbid migraine may further compound this risk, according to the American Academy of Otolaryngology-Head and Neck Surgery 10
Positive screening should prompt detailed assessment using Get Up and Go test, Tinetti Balance Assessment, or Berg Balance Scale, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 15, 10
