quiz 3 part 1 (ear) Flashcards
S+S of a nontraumatic TM rupture?
preceded by a stabbing ear pain, pain is releived after the rupture, post rupture otorrhea
what can cause a nontraumatic rupture?
severe acute otitis media
what suggests an inner ear injury in a TM rupture?
tinnitis, hearing loss, vertigo
how can you diagnose a TM ruputre?
otoscope where it will be visible and audiometry to document conductive hearing loss
treatment of TM rupture?
-surgery if it stays open >3months
-no earplugs or water
-test otorrea to make sure it is not CSF leak from a basilar fracture
-suction blood obscuring the ear canal
-DO NOT irrigate keep it dry
-broad spectrum antibiotic if the ear was contaminated
complications of TM rupture from trauma
-basilar fracture can allow the infection to go into the brain
-fluid can cause infection
what is often the result of a basilar skull fracture?
hemotypanum: blood in the middle ear cavity
-blue black discoloration of the TM
what is ramsey hunt syndrome?
acute facial paralysis in assocation with herpetic blisters/ herpes zoster
-blisters in the ear canal, auricle or bother
-manifestation of shingles
other names for ramsey hunt?
intermedius neuralgia and genticulate neuralgia
pathophysiology of ramsey hunt?
in the ganglion of the seventh cranial nerve
-nervous intermedius is in sensory portion of CN7
ramsey hunt s+s?
deep ear pain, pain radiating toward the pinna, constant dull background pain
-vertigo, tinnitus, ipsilateral hearing loss, facial paresis from inflammation of the facial nerve
-rash and blisters on the anterior 2/3 of tongue, soft palate, external auditory canal and pinna
complication of ramsey?
blisters becoming infected causing cellulitis
ramsey hunt workup:
WBC count, ESR, VZV serology
how are you going to treat ramsey hunt?
-**oral acycolvir **
-corticosteorids
-vestibular suppresants bc of the vertigo
-local anesthetic for otalgia relief
-carbamazepine *especially in the case of nerve pain to the facial nerve (idiopathic genticulate neuralgia
what is someone also has bels palsy with ramsey?
make sure to protect corneal irritation
and injury
-make sure there are no contraindication from the drug
-droppy eye
what is otitis media with effusion?
fluid in the middle ear without S+S of infection
S+S of OM with effusion?
-seorus or mucoid
-opaque or yello
-decrease mobility or air fluid level
-hearing loss, speech effects, language and learning impact
why might otitis media with effusion occur
-allergic rhinitis
-as an inflammatory response to AOM or poor euschian tube hygiene
-nasopharygeal carcinoma
-unresolved AOM
-there is no infection in the fluid
signs of otitis media with effusion?
TM is dull and impaired mobility sometimes cloudy
-air bubbles in the middle ear
-acoustic reflectometry and tympanometry detect fluid
what if the effusion is not resolving?
think malignancy
how to treat OM with effusion?
-cotricosteroids, decongesstants, abx, antihistamine
-tympanostomy (tube insertion) and a myringotomy (if persistant??)
age range for typical OM w effosion?
6 months to 4 years
-in an adult think barotrauma, urti, OR chronic allergic rhinitis
what is a euschian tube dysfunction?
a closed tube the would normally provide ventilation and drainage for the middle ear cleft
what typically precedes a euschian tube dysfunction?
viral uri or allergy
euschian tube S+S
popping and cracking sound (from a partial blockage), aural fullness, fluctuating hearing, dyscomfort (barometric pressure changes)
what will the TM look like in a case of euschian tube dysfunction?
hypomobile due to the build up of fluid
how can we treat euschian tube dysfunction?
pop ears against closed nostrils *DO NOT due this if there is an active intranasal infection
-decongestant
-no barometric pressure changes
-balloon dilation of the tube
complications of euschian tube dysfunction
developing serous otitis media
what predisposes you for a euschian tube dysfunction?
having a patulous tube (wider) bc it is easier to get infected
there is a high chance chronic otitis media is caused by what?
food or inhalant allergy that can help an urti spread to the ear
