ears - specific deafness Flashcards
first step mx in Sudden-onset sensorineural hearing loss
urgent referral ENT
what usually causes Sudden-onset sensorineural hearing loss
idiopathic - can be vestibular schwannoma
invx Sudden-onset sensorineural hearing loss
MRI
mx Sudden-onset sensorineural hearing loss
(in ENT) - oral steroids
where do vestibular schwannomas arise from
cerebollpontine angle - CNVIII nerve sheath
symptoms vestibular schwannomas
(CNVIII) vertigo, unilateral sensorineural hearing loss, unilateral tinnitus
what other cranial nerves can be affected in vestibular schwannomas and what symptoms
V = no corneal reflex // VII = facial palsy
who commonly gets bilateral vestibular schwannomas
NFT 2
invx vestibular schwannomas
MRI cerebellopontine angle (+ audiometry)
symptoms impacted ear wax
pain, tinnitus, vertigo, CONDUCTIVE hearing loss
mx ear wax
drops - olive oil, sodium bicarb, almond oil // or irrigation
contraindication to treatment ear wax
perforation or grommets
what can cause Perforated tympanic membrane
