Q

What is otosclerosis?

A

Most common cause of acquired hearing loss in young adults

Sound vibrations cannot be transmitted effectively to the cochlear
You get gradual unilateral or bilateral CONDUCTIvE hearing loss

Q

What is labyrinthitis?

A

Infection affecting the inner ear, usually viral

17
Q

What does labyrinthitis present with?

A

Acute onset and persistent vertigo, tinnitus and hearing loss
N and V
Fever
It is self limiting

18
Q

What is acute vestibular neuritis?

A

It is similar to labyrinthitis however it is inflammation of only the vestibular nerve, often after a viral infection
It is acute, spontaneous and prolonged vertigo
N and V
Hearing isn’t affected
Self limiting

19
Q

What is presbyacusis?

A

Most common type of sensorineural hearing loss n people over the age of 55
It is progressive and usually bilateral sensorineural hearing loss that occurs in older people as they age

20
Q

What is noise related hearing loss?

A

Loud nose damages the cochlea
Can result in permanent hearing loss and tinnitus
Prevention with protective ear wear
Decreased listening to loud music etc…

21
Q

What can you use for congenital hearing loss

A

Hearing aids
Cochlear implants
Sign language

22
Q

What is chronic suppurative otitis media?

A

Chronic inflammation of the middle ear and mastoid cavity
Recurrent ear discharges (otorrhoea) through a tympanic perforation with conductive hearing loss
No otalgia or fever

It is safe if it doesn’t involve chOlesteatoma
It is not safe if involving Cholesteatoma

23
Q

What can a perforated tympanic membrane be caused by?

A

Trauma, middle ear infection, sudden load noise, barotrauma (air pressure)
Will heal by itself in 6-8 weeks (avoid water initially) if infected use ABx

24
Q

What is a wet perforTed tympanic membrane?

Perforation which occurs in wet. On dictions like surfing and waterskiing
Infection and purulent discharge
Often caused by a pseudomonas species
Heals spontaneously and can take up to 9 months

26
Q
