Data gathering
- Red flags
- acute onset hearing loss + vertigo -> contact ENT on call
- CN symptoms, limb weakness, cerebellar signs, severe headache -> urgent HASU review
- History
- Menieres – ear fullness, tinnitus
- BPPV – head movement triggers vertigo
- Vestibular neuronitis – prodromal viral URTI, continuous spinning, vomiting
- Vestibular migraine – recurrent episodes of vertigo, nausea, photophobia, phonophobia, often normal examination
- Dysequilibrium (unsteadiness)
- multisensory imbalance – elderly patient, vision, proprioception
- Examine
- ENT exam
- CN exam
- Cerebellar exam
- L/S BP
- Dix-Hallpike
- Head impulse test (negative in central causes)
Clinical management
- Investigations
-
- Bloods – FBC, U+Es, TFTs, HbA1c
- Bedside BM
- Audiometry
-
- Treatment
- BPPV
- Epley manoeuvre, Brandt-Daroff exercises, refer if not settled after 4 weeks
- Vestibular neuronitis
- Prochlorperazine (max 3 days), refer if not settled after 4 weeks
- Vestibular migraine
- Only treat if known vestibular migraine – prochlorperazine 5mg TDS, refer if symptoms persist more than 6 weeks
- Multisensory imbalance
- Refer to falls clinic
- BPPV
Notes
- Cerebellar examination
- DANISH
- Dysdiadochokinesia
- Ataxia (gait and posture)
- Nystagmus
- Intention tremor
- Slurred, staccato speech
- Hypotonia/Heel-shin test
- DANISH
- Dix-Hallpike test for BPPV
- Patient in a sitting position
- Rapidly lay the patient down flat on a couch with head turned to the side and neck extended (ensure no neck pathology)
- A nystagmus occurs if BPPV present
- Long term use of prochlorperazine, cinnarizine
- generally recommended to avoid as slows central compensation and creates psychological dependence – advise patients to mobilise as much as possible to compensate quicker
