Ear conditions Flashcards
What is otitis media with effusion?
also known as ‘glue ear’ which is a collection of fluid within middle ear space without acute inflammation
caused by eustachian tube dysfunction, leading to fluid and negative pressure in middle ear affecting hearing
how might glue ear present?
hearing loss, intermittent ear pain with fullness or popping, aural discharge, recurrent ear infections
- retracted and straw coloured TM
how is glue ear managed?
most resolve spontaneously in 2-3 months
if persists and affects school performance may require grommets to equilibriate pressures
what causes acute otitis media?
inflammation of middle ear, caused by virus or bacteria (like strep pneumoniae, H.influenzae)
common in children due to easier passage for infection via smaller eustachian tube
how does otitis media present?
earache, young children tugging ear, fever, restlessness etc - symptoms WITH otoscopic : red, yellow TM, buldging of TM, or perforation of TM §
how is otitis media managed?
admission if severe temperature in child, analgesia, abx amoxicillin for 5-7 days, review if ongoing
what are some complications of otitis media?
can complicate to TM perforation, facial never involvement, mastoiditis or even intracranial complications
what is mastoiditis?
inflammation of mastoid air cells, common in children, occurs following untreated middle ear infections
*redness, tenderness behind ear, otorrhoea, headache, loss of hearing, high temp, swelling behind ear causing ear to stick out otoscopy - buldging red TM, CT head if severe
how is mastoiditis managed?
IV abx, myringotomy to drain middle ear, mastoidectomy if severe
- if secondary to otitis media refer to ENT
what is a cholesteotoma?
abnormal sac of keratinizing squamous epithelium and accumulation of keratin within midde ear or mastoid air cell spaces which get infected and erode bone
how might a cholesteotoma present?
asymptomatic, recurrent discharge foul smelling, conductive hearing loss, rare progression to vertigo, facial nerve palsy etc - attic crust
what is chronic otitis media?
chronic inflammation of middle ear and mastoid cavity with recurrent ear discharge through TM perforation for 2 weeks, complication of acute otitis media
how might chronic otitis media present?
persistent ear discharge without pain or fever, hearing loss in affected, hx of otitis media, glue ear, tinnitus - TM perforation and middle ear inflammation
how is chronic otitis media managed?
urgent admission if serious complication
- referral to ENT, secondary care with abx, steroids and cleaning of ear - keep ear dry etc
*extracranial spread. - red flags: headache, nystagmus, vertigo, fever, labyrynthitis, facial paralysis etc
what is otitis externa?
inflammation of of skin and subdermis of external ear canal, less than 6w, caused by staph. aureus or pseudomonas
