This type of hearing loss can occur due to any condition which interferes with the conduction of sound reaching the cochlea. The lesion may lie in the external ear, tympanic membrane, middle ear or ossicles up to stapediovestibular joint (oval window).
The conductive hearing loss may be congenital or acquired.

Impedance Audiometry:
Useful in intact tympanic membrane to know the cause of conductive hearing loss.
1. Impedance audiometry: Useful in intact tympanic membrane to know the cause of conductive hearing loss.
2. Management: Most cases of conductive hearing loss can be managed by medical or surgical means.
