What is rinne’s test?
Place the fork on the mastoid process and ask the patient to tell you when they stop hearing. Place it infront of the ear at this point and ask if they can hear it again. If they can this, this is rinne’s positive and is not conductive hearing loss.
What is weber’s test?
Place the base of the fork on the middle of the frontal bone and ask if there is a side that is heard louder in. If there is one ear, this is the ear that has a conductive loss and this is Weber’s positive

Normal - mobile ossicles - A-gram
hypermobile ossicles - Ad gram
Fixed ossicles - As-gram

What are the 6Ds of ear symptoms?
Deafness Discomfort Discharge Dizziness Defective facial movement Din din (tinnitus)
Define conductive hearing loss.
A problem between the external auditory meatus and the middle-ear
Give 2 examples of conductive loss
Cholesteatoma
Otitis media
Define sensorineural hearing loss
There is a sensory/neural/both problem that is resulting in hearing loss
What can cause sensorineural hearing loss?
Sensory - cochlea
Neural - problem with the nerves e.g. vestibulocochlear
Deafness can be mixed between sensorineural and conductive - true/false
true
What is central hearing loss?
Both the conductive and sensorineural systems are intact but the patient is deaf due to damage in the acoustic centres of the brain e.g. stroke
Discomfort may be charged by a number of nerves; which nerves.
Vagus/facial/glossopharyngeal/trigeminal/nerves from C2/3.
What other ENT problem may present as earache due to a shared nervous supply?
Referred pain from tonsilitis
What is otorrhoea?
This is discharge from the ear.
Where can dizziness be a problem from?
Ear
Brain
Dizziness and hearing loss often occur together in the inner ear with inflammation of it - true/false

False - can have one with out the other
Define tinnitus
The sound of silence - this is the ringing in your ears when you enter a very quiet room
What should you investigate, in order to exclude, for a patient with tinnitus?
look for a tumour.
Tinnitus, which affects the patient’s QOL is treated using ear drops - true/false
False it is treated by trying to teach the patient to adapt to it.
What percentage of the population does tinnitus ruin lives in?
2%
What is Otitis media with Effusion
This is fluid behind the ear drum in the absence of infection.
