Ears Flashcards
What is Acute Otitis Externa (AOE)?
- infection of the outer ear canal
- AKA swimmer’s ear
What causes Acute Otitis Externa (AOE)?
Excessive moisture or abrasion in the ear canal leading to bacterial or fungal infections
Manifestations of Acute Otitis Externa (AOE)?
Tragal tenderness (pain when the tragus is touched)
- flap over ear
Swelling of the external canal
Ear discharge with odor
AOE Management
Topical treatment for AOE (Acute Otitis Externa)?
2% solution of acetic acid
Fluoroquinolones
What is Acute Otitis Media (AOM)?
Inflammation and fluid in the middle ear
- Can open up a hole @ tympanic membrane
What causes Acute Otitis Media?
Bacterial or viral infections
Manifestations of Acute Otitis Media?
Otalgia (ear pain)
Middle-ear effusion (bulging of the eardrum due to fluid buildup)
Middle-ear inflammation (redness of the eardrum)
What surgeries are used in Acute Otitis Media management?
Tympanoplasty: reconstruction of the tympanic membrane (eardrum)
Ossiculoplasty: reconstruction of the bones of the middle ear (ossicles). Prostheses used to reconnect the ossicles
Mastoidectomy: removal of diseased bone, mastoid air cells, and cholesteatoma to eliminate infection
Stapedectomy: reconnecting to the cochlea.
What is Otosclerosis?
Abnormal bone growth in the middle ear, particularly the ossicles (tiny bones) and limiting their movement.
- This leads to hearing loss.
Surgery for otosclerosis?
Stapedectomy: part of the stapes bone is removed/replaced with a prosthesis to improve hearing by reconnecting to the cochlea.
What is Meniere’s Disease? What causes it?
Imbalance of fluid in the inner ear
- Due to poor absorption of fluid in the endolymphatic sac or a blockage in the endolymphatic duct
Manifestations of Meniere’s Disease?
Tinnitus (ringing in the ears)
Vertigo (spinning sensation)
- Episodic (episodes accompanied by nausea and vomiting)
Head pressure
Fluctuating progressive hearing loss
Management for Meniere’s Disease?
- Dietary changes (low sodium, 2000mg/day)
- Medications (diuretics)
- Surgery: endolymphatic sac decompression or vestibular nerve section
