give risk factors for hearing loss
exposure to excessive noise levels
this type of hearing loss is caused by external of middle ear problem
conductive hearing loss
this type of hearing loss is caused by damage to the cochlea or vestibulocochlear nerve
sensorineural hearing loss
this type of hearing loss is both caused by conductive and sensorineural
mixed hearing loss
this type of hearing loss is caused by emotional problem
functional hearing loss
perception of sound; often “ringing in the ears”
tinnitus
what helps to soften cerumen
glycerin
mineral oil
half strength h202\
peroxide in glyceryl
inflammation most commonly caused by bacteria Staphylococcus or Pseudomonas, or fungal infection from Aspergillus spp
external otitis
rare, progressive infection that affects the external auditory canal, surrounding tissues, and skull
malignant external otitis
sensation of fullness or pain in the ear
otalgia
Manifestations include otalgia (ear pain), fever, and hearing loss
otitis media
treatment for otitis media
antibiotics (amoxicillin)
myringotomy or tympanotomy
fluid in the middle ear without evidence of infection
serous otitis media
result of recurrent acute otitis media
chronic otitis media
reconstruction of the tympanic membrane
tympanoplasty
reconstruction of the bones of the middle ear
ossiculoplasty
are used to reconnect the ossicles to reestablish sound conduction
prostheses
removal of diseased bone, mastoid air cells, and cholesteatoma
mastoidectomy
benign tumor, an ingrowth of skin that causes persistently high pressure in the middle ear
cholesteatoma
what is the common side effect of antibiotics
diarrhea
any altered sense of orientation in space
dizziness
the illusion of motion or a spinning sensation
vertigo
involuntary rhythmic movement of the eyes associated with vestibular dysfunction
nystagmus
infection of the inner ear
labyrinthitis
tumor of the VIII cranial nerve
acoustic neuroma
Abnormal inner ear fluid balance cause by malabsorption of the endolymphatic sac or blockage of the endolymphatic duct
meniere’s disease
what is triad symptoms of meniere’s disease
hearing loss
tinnitus
vertigo
what type of hearing loss is present in meniere?
sensori or conductive
sensori
what are the drugs for meniere’s disease symptoms
MTAD
meclizine (antivert)
tranquilizer valium
diuretics (thiazide)
an auditory prosthesis used for people with profound sensorineural hearing loss bilaterally who do not benefit from conventional hearing aids
cochlear implant
