Cards

Term
Cerumen impaction
Definition
S/sx: conductive hearing loss. Exam shows cerum in canal.
Tx: 3% H2O2 or irrigation only if TM is intact. Remove only if symptomatic- hearing loss, ear pain, fever, facial paralysis. If asymptomatic, leave since cerumen has a purpose.
Removal: curettes, lavage, cerumenolytics, suction.
Term
Foreign bodies in ear
Definition
More common in children. Firm materials may be removed w/ loop or hook. Aqueous irrigation shouldn't be performed for organic bodies because they will swell. Live insects should be immobilized w/ lidocaine before removal.
Term
Conductive hearing loss
Definition
obstruction (cerumen), middle ear effusion, stiffness effect (otosclerosis), discontinuity (ossicular disruption), transient auditory tube dysfxn associated w/ URI. Persistant usually due to chronic ear infection, trauma or otosclerosis.
Weber test shows lateralizatoin to impaired ear. and Rinne shows BC=AC or BC>AC.
Term
Sensorineural hearing loss
Definition
Sensory results from deterioration of chochla usually due to loss of hair cells fromt he organ of Corti. Presbyacusis (age related) is common. Also noise exposure, head trauma, DM. Neural loss occurs w/ lesions involving CN VIII, auditory nuclei, ascending tracts or auditory cortex: neuroma, MS, cerebrovascual dz.
Term
Tinnitus
Definition
Perception of abnormal ear or head noises. OFten assoc w/ conductive hearing loss. May indicate vascualr abnormality: glomus tumor, carotid vaso-occllusive dz, AV malformation or aneurysm.
Term
External otitis
Definition
S/Sx: otalgia, pruritis, purulent d/c. Often a hx of recent H2O exposure or mech trauma. Commonly G- rods Pseudomonas, Proteus or fungi (aspergillus). Exam shows erythema and edema of ear canal skin and pain w/ manipulatin of auricle. TM is mobile.
Tx: irrigate w/ H2O2 or vinegar. Dry canal. ABX: cipro, cortisporin. Otic drops of aminoglycoside abx and steroid ONLY if TM is intact.
Term
Malignant otitis externa
Definition
50-60% mortality w/o abx. Spread of infection to soft tissue, bone. At risk pt: DM and immonocompromised.
S/sx: persistant foul d/c, granulations, deep pain. PE shows otorrhea, edema, necrosis.
Tx: IV abx
Term
Acute otitis media
Definition
bacterial infection precipitated by viral URI. S/sx: pain, aural pressure, decreased hearing, +/- fever. PE shows erythema, Bulging TM with decreased mobility, mastoid tenderness.
Tx: abx w/ nasal decongestant. Amox, sulfa, augmentin for resistance
Term
Acute masoiditis
Definition
Evolves following several weeks of inadequately tx'd AOM
S/Sx: posauricular pain, erythema, fever. X-ray shows coalescence of mastoid air cells.
Tx: IV abx, mastoidectomy
Term
Acute and serous otitis media
Definition
when auditory tube remains blocked pressure results in transudation of fluid most common in kids due to narrow, horizantal tubes.
S/Sx: usually follows URI or barotrauma. TM is dull and hypomobile, air bubbles and conductive hearing loss.
Tx: oral corticosteroids, oral abx
Term
Chronic otitis media
Definition
S/Sx: purulent d/c, TM often perforated, pain uncommon. Conductive hearing loss.
Tx: regular removal of debris, ear plugs for prevention of H2O exposure, topical abx drops for exacerbations.
Term
Otitis media pathogens, abx tx and referral
Definition
Strep pneumonea, Haemophilus influenza, Streptococcus pyogenes.
Amox, E'mycin, sulfonamide. Resistant cases use cefaclor or amoxicillin-clavulanate.
Refer pt's w/ complications (mastoiditis, petrous apicitis, facial paralysis) or chronic cases
Term
Vertigo
Definition
Sensation of motion when there is no motion or exaggerated sense of movement. Peripheral: onset sudden w/ tinnitus, hearing loss and horizantal nystagmus.
Central: gradual onset, vertical nystagmus.
Exam: romberg, gait
Term
Meniere's dz
Definition
distention of endolymphatic compartment of inner ear.
S/sx: episodic vertigo 1-8hr; low-frequency sensorineural hearing loss; tinnutus low-tone; sensation of aural pressure.
Term
Vestibular neuronitis
Definition
paroxysmal single attack of vertigo w/o accompanying impairment of hearing.
S/Sx: nystagmus, vertigo may persist for days to weeks
Term
Vertigo assoc w/ MS
Definition
Central lesion that becomes disabling.
Term
Positioning vertigo
Definition
Due to free-floating otoconia w/in wemicirular canal. Transient vertigo following changes in head position lasting 10-60 sec. Occurs in clusters lasting several days. Tx is Pt.
Term
cervical vertigo
Definition
position receptors in facets of c-spine dysfxn. Vertigo triggered by neck movements.
Term
Traumatic vertigo
Definition
labyrinthine concussion most common. Sx diminish w/in days.
Term
Perilymphatic vertigo
Definition
Leakage of perilymphatic fluid from inner ear to tympanic cavity via round or oval window resulting from injury, barotrauma or vigorous valsalva
Term
Viral rhinits
Definition
cause: rhinovirus, adenovirus, strep, H flu, Staph
S/sx: HA, nasal congestion, watery rhinorrhea, sneezing, malaise.
Tx: degongestants
Term
Allergic rhinits
Definition
cause: allergens.
s/sx: eye irritation, turbinates pale or violaceous, +/- nasal polyps.
Tx: antihistimines
Term
Rhinitis medicamentosa
Definition
cause: use of nasal spray >3d.
s/sx: rebound congestion often worse tahn original complaint.
Tx: complete cessatoin of sprays
Term
acute sinusitis
Definition
cause: dz that swell mucous membrain causing mucociliary obstruction. Strep, H flu
S/Sxx: 1-4wk of secretion from green to yellow, PND, HA, cough
Tx: decongestants. Abx if s/s over 10-14d or severe (fever, facial pain, swelling)
Term
Viral pharyngitis
Definition
S/sx: gradual onset of rhinorrhea, cough, diarrhea. May have fever (adenovirus, HSV), pharyngeal vesicles (coxsackie), tonsilar enlargement and exudate (EBV).
Tx: fluids, tylenol, rest
