Introduction Presbyacusis : sensory neural hearing
loss, gradually ,in elderly, degeneration disorders, bilateral, symmetric, start in high frequencies
Limitation in communicationIsolated
Epidemiology demography1990, >65 yr : 6,7 million people 2020 estimation :18,8 million
people Prevalence presbyacusis >65 yr : 30 %>75 yr : 50%
Presbyacusis in Indonesia : 9,3 million peopleUS census Bureau International
Data Base th 2004
Epidemiology1 off 3 American, age 65-75 yr suffer
hearing loss The National Institute on Deafness &
other Communication Disorders
(NIDCD)
8,58 million England suffer hearing loss : 75% age >60 yr
The UK National Study of Hearing Disorder 1995

Prevalence
National Academy on an aging society Hearing loss-A Growing Problem that effect quality of life.Des 1999
EtiologiAtherosclerosis /cardiovascular diseasesDiet and metabolismAccumulation noise inducedDrugs/ toxic substances StressGenetic
DIAGNOSIS• Screening • Anamnesis Otoscopy Tuning fork tes Pure tone Audiometri Speech Reception Test (SRT) Speech discrimination scor (SDS)
Anamnesis : Aged >60 yearsHearing impaired slowly, progressive,&
symmetries, TinnitusDifficulties hearing in noise
(Cocktail party deafness)Pain in hearing loud sound(recruitment)
Diagnosis
SymptomSlowlyImpaired in high frequenciesWomen and children voice difficult to hearTinnitusRecruitment
Sign and Symptom
High frequency hearing loss. Gradually, bilateral and symetricDifficulty in differentiated the consonant
s, r, n, c , h, ch. Coctail party deafness. Recruitment : over increasing sensitivity
Audiology Test DiagnosticPure tone
Audiometry
Speech Reception Test (SRT)
Speech Discrimination Score (SDS)
Physical examination/ Otoscopy normal
Audiogram : sensory neural hearing loss in >1000Hz frequency
Speech Audiometric test : Speech discrimination score decrease

Management:NeurotonicAvoid loud noise, ototoxic Annual hearing testRehabilitation:
Hearing aid, lip reading & auditory training

PrognosisProgressiveAvoid etiology factors
Impact of lifeQuality of lifeSocial isolatedLess activitiesDepression emotional problemFrustrated othersLess Interpersonal relationship Lonely
Quality of life Hearing problem could impact function
and psichosocial life such as :Daily comunication Phone comunication (social and
emergency) Social attitudeFamily relationship, activity and time
leisureSafetyIndependent living.
SummaryChanges in Presbyacusis :Changes cochlea structures and audit0ry
nerves Atrophy and hair cell degeneration in organ
CortyChanges vascularisation and decreasing
volume and size of nerves
SummaryPresbyacusis could
managed properlyNeed early
identification Psychosocial impact
should be consider Try to identification of
etiology and specific problem.
Need support from family, friends and surrounding
