The document outlines the three main types of hearing loss: conductive, sensorineural, and mixed, along with their causes. Conductive hearing loss can be due to issues in the outer or middle ear, while sensorineural hearing loss is related to the inner ear. Mixed hearing loss involves both conductive and sensorineural factors, and various causes are listed, including infections, trauma, and genetic factors.

1. Causes of Hearing Loss

2. Types of Hearing Loss
There are 3 main types of Hearing Loss based on the site of lesion -
● Conductive Hearing Loss - caused due to problems in the outer or
middle ear.
● Sensorineural Hearing Loss - caused due to problems in the inner ear.
● Mixed Hearing Loss - caused due to problems in both the Conductive
(i.e., outer and/or middle ear) and the Sensorineural counterpart (i.e.,
in the inner ear).

3. Let’s take a look at the
causes of these
Three Types of Hearing Loss
respectively

4. Conductive Hearing Loss
● Malformation in outer ear,
ear canal, eardrum, or
middle ear structure
● Fluid build-up in middle ear
due to colds
● Ear infection like Otitis
Media
● Perforated eardrum
● Allergies
● Excessive accumulation of
earwax
● Foreign object in the ears
● Overexposure to loud noises
● Prescubysis (ageing)
● Malformation of the inner ear
● Hereditary reasons
● Head trauma
● Meniere's disease
● Autoimmune disease
● Otosclerosis
● Tumors
Sensorineural Hearing Loss

5. Mixed Hearing Loss
● When a Sensorineural Hearing Loss is compounded by
Conductive Hearing Loss
● Developmental abnormalities or malformations in both
the outer and/or the middle ear and the cochlea
● Sensorineural damage in the inner ear - such as the
cochlea
● Damage in the auditory nerve

6. Too Much
Exposure to
Loud
Decibels of
Noises

7. Genetic
Factors

8. Ear
Infections -
like Otitis
Media, an
inflammatory
disease of
the Middle
Ear

9. Otosclerosis -
When one of
the 3
Ear bones
or Ossicles
is unable to
Vibrate freely

10. Meniere’s
Disease -
it causes
Vertigo

11. Diabetes

12. Hearing
Loss due to
Old Age or
Prescubysis

13. Perforated
Eardrum

14. Ototoxic
Medications

15. Smoking
or
Intake of
Alcohol

16. Head Trauma
or Brain Injury

17. Diseases, Viruses, Infections,
including -
● Meningitis
● Measles
● Mumps
● Chicken Pox
● Influenza
