ENT Flashcards
1

Sensing head movement - the vestibular system
2

4
Q
How is sudden onset sensory neural hearing loss treated
A
high dose cortical steroids
5
Q

Sound will be Louder in the normal ear as a normal ear it’s better sensing the sound
6
Q
The Web is test results in conductive hearing loss

Mx of SN hearing loss
> hearing aids/ ADL - mild to moderate
> cochlear implant - severe to profound not benefitting from hearing aids
246
indications for cochlear implant
In children, audiological assessment and/or difficulty developing basic auditory skills.
In adults, patients should have completed a trial of appropriate hearing aids for at least 3 months
247
risks of cochlear implant
nfection, facial paralysis due to nerve injury intra-operatively, cerebrospinal fluid (CSF) leakage, and meningitis - should have up to date injections to strep and haemophilis
248
CI to the cochlear implant
Lesions of cranial nerve VIII or in the brain stem causing deafness
Chronic infective otitis media, mastoid cavity or tympanic membrane perforation
Cochlear aplasia

Anterior versus posterior nosebleeds
> anterior: Visible source of bleeding usually occurs due to an insult to the capillaries
> posterior: More profuse and originate from deeper structures

> comorb - like severe HTN, CAD
Child under two
256
If bleeding does not stop after 10-15 minutes of continuous pressure on the nose consider
> Cautery - Should be used as the initial measure if the source of bleeding is visible and caught tree is tolerated (involves silver N)
> Packing may be used if Cautrey is not tolerated or bleeding point cannot be visualized
257
Nosebleeds and hemodynamically unstable patients
control bleeding with first aid measures in the interim
patients with a bleed from an unknown or posterior source (i.e. the bleeding site cannot be located on speculum, bleeding from both nostrils or profuse) should be admitted to hospital.

this is normal and means that the patient either has no current symptoms or a central cause is causing the symp
262
Peripheral versus central vertigo
Peripheral problem, usually affecting the vestibular system
Central problem, usually involving the brainstem or the cerebellum -> sustained non positional vertigo
263
causes of central vertigo
> posterior circulation infarction
> tumour
> MS
> vestibular migraine
264
post circ stroke
sudden onset and may be associated with other symptoms, such as ataxia, diplopia, cranial nerve defects or limb symptoms
265
vertigo & driving
patients must not drive and must inform the DVLA if they are liable to “sudden and unprovoked or unprecipitated episodes of disabling dizziness”.
266
symptoms of nasal septum haematoma
may be precipitated by relatively minor trauma
the sensation of nasal obstruction is the most common symptom
pain and rhinorrhoea are also seen
on examination, classically a bilateral, red swelling arising from the nasal septum
267
nasal septal haematoma vs deviated nasal septum
Nasal septal haematomas are typically boggy whereas septums will be firm
