Inner ear disease Flashcards
describe BPPV and its symptoms
transient (seconds) feeling of movement
caused by loose calcium carbonate crystals within the ear
can follow head trauma or inner ear disease but most often spontaneous
what is the treatment of BPPV
normally self limiting
Epley manouver
what is the investigation for BPPV
Halpike manouver
describe vestibular neuronitis (labyrinthitis) and its symptoms
caused by inflammation of the vestibular nerve
sudden severe attack of vertigo, normally lasting 2-3 days
what is the treatment for vestibular neuronitis
often self limiting
vestibular sedatives - can use prochlorperazine/cinnarzine for short term periods
physiotherapy
how does Menieres disease present
causes episodes of vertigo lasting minutes-hours with associated fluctuating hearing loss and tinnitus
patients often describe a feeling of aiural presure
what is thought to cause Menieres disease
thought to be due to an increase in pressure in one of the fluid compartments in the ear
how do you treat menieres disease
normally self limiting, but hearing loss can start to become permanent
- low salt and caffeine diet
- betahistine - reduces pressure
- intratympanic injections
how does a vestibular migraine present
similar to menieres disease - attacks of vertigo lasting minutes to hours, but without hearing loss/tinnitus
- headache
- visual disturbance
- numbness
what should you do in unilateral tinnitus
MRI to exclude CPA tumour
what is a vestibular schwannoma and when should you exclude it
a slow growing but benign tumour, occurs in 1% of patients with unilateral symtpoms
