What is presbycusis?
Presbycusis = Age-related, bilateral, symmetrical sensorineural hearing loss affecting high frequencies first.
Commonest form of adult hearing impairment
Is presbycusis conductive or sensorineural?
Sensorineural.
Which frequencies are lost first in presbycusis?
High-frequency sounds.
Is presbycusis usually symmetrical or asymmetrical?
Symmetrical.
Name modifiable risk factors for presbycusis.
Chronic noise exposure, smoking, hypertension, diabetes, ototoxic medications
NICE emphasis: reduce modifiable risks → noise protection, CV risk factor management.
Which non-modifiable factors increase presbycusis risk?
Age, male sex, family history.
What symptom commonly accompanies presbycusis?
Tinnitus.
Was are the presenting features of presbycusis?
Why might presbycusis be mistaken for cognitive decline?
Hearing loss can impair communication and is associated with higher dementia risk.
What is the investigation of choice for diagnosing presbycusis?
Assessment for presbycusus:
What audiometry pattern is seen in presbycusis?
Sensorineural loss with preserved low frequencies and reduced high frequencies.
What would Rinne’s test show in presbycusis?
Rinne positive (air > bone).
What would Weber’s test show in presbycusis?
Sound lateralises to the better ear (sensorineural pattern).
Can presbycusis be reversed?
No, it is irreversible.
What is first-line management for presbycusis according to NICE?
Name communication strategies to help patients with presbycusis.
Reduce background noise, face-to-face conversation, good lighting, lip reading support.
What lifestyle measures can help prevent or reduce presbycusis progression?
Noise protection, CV risk factor control, avoiding ototoxic drugs.
When should asymmetrical hearing loss be referred for investigation?
Refer to ENT urgently to rule out vestibular schwannoma (MRI IAM).
Which occupational groups are at high risk of presbycusis from noise exposure?
Construction workers, woodworking, heavy industry.
Why is treating hearing loss important beyond communication?
Improves quality of life and may reduce dementia risk.
When do you refer for hearing loss?
Definition of sudden sensorineural hearing loss (SSNHL)
SSNHL: Hearing loss over less than 72 hours with no conductive cause.
More detailed:
* Sensorineural hearing loss developing over < 72 hours
* No conductive cause identified
* Otological emergency → requires immediate ENT referral (within 24 hrs) if onset within 30 days
Is SSNHL an emergency?
Yes, it is an otological emergency requiring immediate ENT referral.
