Meniere Flashcards
what is the typical presentation of Meniere?
Intermittent vertigo, tinnitus, sensorineural hearing loss (low frequencies - can last up to an hour) (+ N+V)
define meniere’s disease?
Recurrent episodes of tinnitus, paroxysmal vertigo and unilateral fluctuating hearing loss- can last up to an hour
outline the aetiology of meniere’s disease
Disturbed homeostasis of endolymph (fluid in the inner ear) - impaired absorption/ overproduction
POSSIBLE THEORY: During acute attach the XS fluid pressure causes distention and rupture of Reissner’s membrane which can cause release of endolymph into perilymphatic spaces causing a sudden hearing loss, vertigo and tinnitus. Between attacks the Reissner’s membrane may reattach itseld restoring chemical balance
Disease = idiopathic; syndrome = secondary to a number of known inner-ear disorders
what are the presenting symptoms of meniere’s disease?
Vertigo(WORLD AROUND YOU IS SPINNING)
Loss of hearing in affected ear (@ start it is during vertigo spells but later stages it may become constant) - occurs in affected ear and starts at low frequencies
Tinnitus– occurs in affected ear
sensation of fullness
Loss of balance
Headaches
Nausea/vomiting
what is seen on examination in Meniere’s disease?
positive Romberg’s test and Fakuda’s stepping test(turning towards affected side when asked to march in place with eyes closed)
Positive romberg’s test (feeling unsteady when eyes closed) indicated a proprioceptive issue
what are the appropriate investigation for Meniere’s disease?M
Positive Romberg
Fukuda/Unterbergertest ( marching on spot) -> Cant hold position and turns to affected side
Reinnes and Webers test: unilateral sensorineural loss
Poor tandem walking
Exclusion MRI- MRI is done for any patient with asymmetrical hearing loss, primarily to exclude acoustic neuroma.
If the patient has bilateral symptoms and a poor response to treatment, AI testing may be conducted e.g.ANA antibodies, Rh factor.
