Ménière’s

Disease

OVERVIEW

Idiopathic disease an abnormal inner ear fluid

balance caused by a mal-absorption of fluid in the endolymphatic sac

a blockage in the endolymphatic duct

regardless what cause it, endolymphatic hydrops develops.

NORMAL

DILATED

OVERVIEW

more common in adults an average age of onset in the 40s with symptoms usually beginning

between the ages of 20 and 60 years

common in both genders the right and left ears are affected

with equal frequency

CLINICAL MANIFESTATIONS fluctuating, progressive

sensorineural hearing loss tinnitus or a roaring sound a feeling of pressure or fullness in

the ear episodic, incapacitating vertigo,

often accompanied by nausea and vomiting

2 SUBSETS OF MENIERE’S DISEASE

Cochlearfluctuating, progressive sensorineural hearing loss associated with tinnitus and aural pressure in the absence of vestibular symptoms or findings.

Vestibularcharacterized as the occurrence of episodic vertigo associated with aural pressure but no cochlear symptoms

ASSESSMENT & DIAGNOSTIC FINSINGS A careful history is taken to determine

the frequency, duration, severity, and character of the vertigo attacks.

MEDICAL MANAGEMENT Can be successfully treated

with diet and medication therapy

Many patients can control their symptoms by adhering to a low-sodium (2,000 mg/day) diet

SURGICAL MANAGEMENT

Endolymphatic Sac Decompression equalizes the pressure in the

endolymphatic space favored by many otolaryngologists as a

first-line surgical approach to treat the vertigo of Ménière’s disease

SURGICAL MANAGEMENT

Middle and Inner Ear Perfusion used to decrease vestibular function and

decrease vertigo ototoxic medications, such as streptomycin

or gentamicin, can be given to patients by infusion into the middle and inner ear

SURGICAL MANAGEMENT

Intraotologic Catheters catheters are being developed to provide a

conduit from the outer ear to the inner ear uses of these catheters include treatment

for sudden hearing loss and various disorders causing intractable vertigo

SURGICAL MANAGEMENT

Vestibular Nerve Section provides the greatest success rate

(approximately 98%) in eliminating the attacks of vertigo

cutting the nerve prevents the brain from receiving input from the semicircular canals

NURSING MANAGEMENT

Nursing Dx: Risk for injury related to altered mobility because of gait disturbance

1.Assess extent of disability in relation to activities of daily living.

2.Recommend that patient keep eyes open and stare straight ahead when lying down and experiencing vertigo.

2. Place pillow on each side of head to restrict movement.

3. Encourage patient to sit down when dizzy.

Nursing Dx: Risk for deficient fluid volume related to increased fluid output, altered intake and medications

1.Monitor intake and output.

2.Assess indicators of dehydration (e.g. pulse, skin turgor, blood pressure, mucous membranes).

3.Encourage oral fluids as tolerated; discourage beverages containing caffeine.
