Disorders
Can cause perforation of tympanic membrane
infection, trauma to ear, inserting foreign objects
Caused by eustachian tube obstruction or dysfunction, air bubbles may be visualized in middle ear
Serous otitis media
Test used to determine conductive hearing loss
Weber test
Used to diagnose tinnitus
An audiogram speech discrimination test or a tympanogram
Meds for acute otitis media
broad spectrum antibiotic and otic preparation for drainage
A complication of otitis media
Labyrinths
Nursing management for external otitis
educate patients to not clean the external
ear canal with Q tips, avoid events
that leads to infections, avoid getting the canal wet, can use a water-insoluble
gel placed in the ear as a barrier to prevent water getting in, and tell patients that infection can be prevented by using antiseptic otic preparations
Sounds over this decibel can cause noise induced hearing loss
85-90 dB
Ways to remove foreign objects from ear
Irrigation, suction, or instrumentation
What must be monitored when administering aminoglycosides
auditory levels and kidney function
can destroy the vestibular nerve, only known risk factor is cell phone usage, S/S include tinnitus, hearing loss, and vertigo.
What is acoustic neuroma
Clinical manifestations of otitis media
hearing loss, persistent or intermittent foul-smelling otorrhea, pain, perforation of the tympanic membrane, cholesteatoma
Sensorineural-caused by a defect in the ___________ (multiple answers)
cochlea, eighth cranial
nerve, vestibulocochlear nerve, or the brain itself
Complications to watch for following surgical removal of acoustic neuromas
facial nerve paralysis, cerebrospinal fluid leakage, meningitis, cerebral edema
Management for motion sickness and their main side effect
OTC antihistamines and anticholinergics; drowsiness
A fluctuating, progressive sensorineural hearing loss associated with tinnitus and aural pressure
Cochlear Meniere Disease
Includes otalgia, otorrhea, fever, and hearing loss
Signs/Symptoms of acute otitis media
Can increase risk or cause sensorineural hearing loss in older adults
diabetes and ototoxic medications
an incision in the tympanic membrane to relieve pressure and to drain serous or purulent fluid from the middle ear
myringotomy (and tympanostomy if tubes are placed)
List ototoxic drugs
Aminoglycosides, Aspirin, NSAIDs, Diuretics, antibiotics (-mycins), chemo drugs
A dilation of the endolymphatic space, excessive build-up of the endolymph fluid fills the inner ear, can rupture the inner membrane
Endolymphatic hydrops (Menieres Disease)
A rarer, progressive, debilitating infection of the external auditory canal, the surrounding tissue, and the base of the skull.
What is Malignant external otitis
Risk factors of hearing loss
mal formation of ear structures, family history, low birth weight, bacterial meningitis, recurrent ear infections
Two types of surgical procedures to treat vertigo and how do they work
Endolymphatic sac decompression equalizes the pressure in the endolymphatic space.
Vestibular nerve sectioning cuts the vestibular nerve to decrease vertigo
Prescribed this for 1-2 weeks when experiencing acute vertigo
Meclizine
