The journal aims to promote latest information and provide a forum for doctors, researchers, physicians and healthcare professionals to find most recent advances in the areas of ENT. Austin ENT: Open Access accepts research articles, reviews, mini reviews, case reports and rapid communication covering all aspects of ENT. Austin ENT: Open Access strongly supports the scientific up gradation and fortification in related scientific research community by enhancing access to peer reviewed scientific literary works. Austin Publishing Group also brings universally peer reviewed journals under one roof thereby promoting knowledge sharing, mutual promotion of multidisciplinary science.

3. INTRODUCTION
Association between advanced age and high
tone deafness was first discovered by
ZWAARDEMAKER in 1899.
Presbycusis is the most common
otolaryngologic problem of elderly.
It involves bilateral high frequency hearing
loss associated with difficulty in speech
discrimination and central auditory processing of
information.

4. DEFNITION
Presbycusis is a sensorineural hearing
disorder. It is most commonly caused by
gradual changes in the inner ear.
The cumulative effects of repeated
exposure to daily traffic sounds or
construction work, noisy offices, equipment
that produces noise and loud music can
cause sensorineural hearing loss.

6. TYPES OF
PRESBYCUSIS
Sensory
Neural
Strial
Cochlear conductive
Mixed presbycusis
Intermediate presbycusis

7. CLINICAL FEATURES
Insiduous onset
Symmetric SNHL
Progressive loss with age
No other otologic diseases
Normal ear examination

8. IMPACT OF PRESBYCUSIS
No visible infirmity
Those interacting with him/her may not
take helpful measures
Forces him to continuously ask for help
Fosters a sense of disability
Voluntarily remain
In isolation at parties
May eventually withdraw from social
situations

9. CAUSES
Atherosclerosis
Diet and metabolism
Accumulated exposure to noise
Drug and environmental chemical
exposure
Genetics
stress

10. PREVENTION AND
TREATMENT
Prevention:
Counseling
Periodic otologic examination
Annual audiograms in high risk patterns
Career or life style change
Treatment:
No effective surgical or medical treatment

11. ALTERNATIVE
MEDICINE
30% dietary caloric restriction
Antioxidant therapy- vitamin
A supplements
Control
diabetes/hyperlipidemia

12. PROGNOSIS
Majority:
Slow deterioration
Neural presbycusis:
Worsen more rapidly

13. REHABILITATION
Precise hearing aid fitting
Hearing assistive devices
Lip reading classes
Possible cohlear implantation
