Q

labyrinthitis vs Menieres

A

both have tinnitus, vertigo, hearing loss
Menieres comes in 1-2 hour episodes and is not curable
labyrinthitis epodes can last longer eg days and you can recover/is curable
labyrinthitis = recent history of cold/infection, intense for few days then goes away slowly
Menieres = no obvious recent trigger, comes and goes

Q

what is a cholesteatoma and what happens if it gets infected

A

growths of keratinising squamous cells that form in the attic of the ear (area of middle ear behind tympanic membrane) - shows as a visible white mass behind the eardrum
non cancerous but can be erosive to surrounding structures
if infected: produce chronic foul-smelling discharge, and debris fills the ear canal, causing hearing loss, facial nerve paralysis, intracranial abscess
