EAR DISORDERS Flashcards
a hydrophobic protective covering of the ear canal against water damage, infection, trauma, and foreign bodies
Cerumen
is the accumulation of cerumen causing obstruction in the external ear
Cerumen Impaction
What causes cerumen impaction?
S-swimmer’s ear
C- Conditions of the skin (asthma)
U- Unnecessary ear cleaning
B- Blockage within the ear canal
A- Autoimmune conditions
Clinical Manifestations of Cerumen Impaction
-Sensation of fullness inside ear
- Conductive Hearing loss
- Ear pain
Prevention of Cerumen Impaction
-Don’t clean ears with cotton buds
- Wear earplugs when swimming
The rationale on why ears don’t need to clean with cotton buds
The ears are self-cleaning and do not need to be cleaned unless there is cerumen impaction
Management for Cerumen Impaction
Irrigation of the Ear Canal
- Soften cerumen by instilling mineral oil or half- strength hydrogen peroxide (H202) 3o minutes prior to procedure
-Straighten the ear canal
- Warm saline irrigation is gently flushed toward the roof of the ear canal
-Position patient on affected side
-Instrumentation
The rationale on position the patient on affected side in the management of cerumen impaction
To promote drainage of fluids
Is the inflammation or infection of the external auditory canal (EAC)
Otitis Externa
Also called “Swimmer’s Ear”
Otitis Externa
Risk is increased with continuous water exposure of EAC and local trauma
Otitis Externa
Common pathogens of Otitis Externa
-Pseudomonas aeruginosis (yellow green)
- Staphylococcus aureus (creamy white)
Nerve impulse
Organ of corti
What are the 3 ossicles?
-Maleus
- Ileus
- Stapes
Medical Management of Otitis Externa
-Otic Preparations
-Ciprofloxacin Otic
-Ofloxacin Otic
-Alcohol Vinegar Otic Mix (Homemade)
- 50% rubbing alcohol, 25% white vinegar, 25% distilled water
-Used as prevention of or as flushing solution for fungal infections
Used as a prevention of or as flushing solution for fungal infections
Alcohol vinegar otic mix (Homemade)
Clinical manifestations of Otitis Externa
- Aural tenderness
-Ear pain - Otorrhea, initially clear but quickly becomes purulent and foul-smelling
-Hearing loss - Erythema, edema, and narrowing of EAC
-Fever (occasional
Hallmark sign of Otitis Externa
Aural Tenderness
Is any inflammation in the middle ear regardless of the etiology or pathogenesis
Otitis Media
Generally, less common among adults
Otitis Media
Characterized by changes in tympanic membrane (TM)
Otitis Media
Characteristics of Normal Tympanic Membrane
pearly-grey, translucent, and shiny
Characteristics of TM in Acute Otitis Media
Bulging TM
Characteristics of TM in Chronic Otitis Media
Retracted TM
Acute infection of the middle ear lasting less than 6 weeks
Acute Otitis Media
Usually precipitated by an Upper RTI
Acute Otitis Media
Clinical Manifestations of Acute Otitis Media
-Bulging tympanic membrane
-Otalgia
- Otorrhea
- Hearing loss
- Fever
Sudden relief is an indicator of TM perforation
Otalgia
