ENT Flashcards
2 types of hearing loss
- Conductive : problem with sound travelling from environment to inner ear
- Sensorineural : problem with sensory system or vestibulocochlear nerve in the inner ear
Causes of sensorineural hearing loss
-> Sudden sensorineural hearing loss (over less than 72 hours)
-> Presbycusis (age-related)
-> Noise exposure
-> Ménière’s disease
-> Labyrinthitis
-> Acoustic neuroma
-> Neurological conditions (e.g., stroke, multiple sclerosis or brain tumours)
-> Infections (e.g., meningitis)
-> Medications
what medications can cause hearing loss ?
~ Loop diuretics - rare (e.g., furosemide)
~ Aminoglycoside antibiotics (e.g., gentamicin)
~ Chemotherapy drugs (e.g., cisplatin)
Causes of adult onset conductive hearing loss
- Ear wax (or something else blocking the canal)
- Infection (e.g., otitis media or otitis externa)
- Fluid in the middle ear (effusion)
- Eustachian tube dysfunction
- Perforated tympanic membrane
- Otosclerosis
- Cholesteatoma
- Exostoses
- Tumours
what is presbycusis and what kind of hearing loss is it
- Age related hearing loss
- Sensorineural
Explain the type of hearing loss in presbycusis
- High-pitched sounds first and more notably than lower pitched sounds
- Occurs gradually and symmetrically
8 RF for Presbycusis
Increased Age (biggest)
Male gender
Family history
Loud noise exposure (Key RF!)
Diabetes
Hypertension
Ototoxic medications
Smoking
Explain the presentation of presbycusis
- Gradual and insidious
- Speech difficult to hear due to it affecting HIGH pitched sounds more
- May be associated with tinnitus
How is presbycusis diagnosed 3 steps to management
- Audiometry = sensorineural hearing loss pattern with normal or near normal hearing at lower frequencies an worsenign hearing loss at higher frequencies
- Optimise the environment, hearing aids, cochlear implants
Definition of sudden sensorineural hearing loss (SSNHL)
Hearing loss over less than 72 hours
Most common cause of SSNHL
Idiopathic (90%)
Diagnosis of SSNHL
- Loss of at least 30 decibels in 3 consecutive frequencies on an audiogram
Management of SSNHL GP and then ENT management if idiopathic
- Immediate referral to ENT within 24 hours
- No underlying cause = high dose oral pred 7 days
- Reduced or altered hearing
- Popping noises or sensations in the ear
- A fullness sensation in the ear
- Pain or discomfort
- Tinnitus
- SX worse when external air pressure changes
Diagnosis and 3 common causes
Eustachian Tube Dysfunction
- Viral URTI
- Allergies (e.g. hayfever)
- Smoking
what would be seen on tympanometry in eustachian tube dysfunction
- The air pressure in the middle ear may be lower than the ambient air pressure because new air cannot get through the tympanic membrane to equalise pressures
- As a result = tympanogram will show peak admittance with negative ear canal pressures
Treatment options for Eustachian tube dysfunction and the main procedure
- Valsalva manoeuvre
- Decongestant nasal sprays (short term only)
- Antihistamines and a steroid nasal spray for allergies or rhinitis
- Surgery may be required in severe or persistent cases

Typical presentation of otosclerosis

- Unilateral or bilateral hearing loss, tinnitus
What kind of hearing loss is seen in otosclerosis
- Conductive
- Affects lower pitched sound more than higher.
- Hears female speech more easily than males.
- Hears voices loud in comparison to environment leading them to talk quietly
what will be seen on examination in otosclerosis
- Otoscopy = normal
- Weber’s = normal if bilateral OR louder in more affected ear.
- Rinne’s = conductive hearing loss. Sound will be easily heard when on mastoid but they will not hear the sound in air
Initial investigation of choice for diagnosing otosclerosis and what will it show ?
- Audiometry = conductive hearing loss
- Bone conduction readings will be normal (0-20 dB)
- Air conduction readings will be greater than 20 dB, plotted below the 20 dB line
What will be seen on tympanometry and high resolution CT in otosclerosis
-> Tympanometry = reduced admittance of sound.
-> High resolution CT = detect the boney changes
Management options for otosclerosis
- Conservative = hearing aids
- Surgical (stapedectomy and stapedotomy)
Explain the two surgical options used in otosclerosis
-> Stapectomy = remove stapes bones and replacing with prosthesis
-> Stapedotomy = removing part of stapes bone but leaving footplate.
