Q - How do we hear?
Q - What is conductive deafness and how it can be treated.
A - Ear is divided into three parts – outer ear, middle ear and inner ear. The sound travels from the outer ear through the ear drum, the middle ear and then via the small bones of the middle ear it reaches the inner ear. This conduction of sound may be interfered by
a) wax or fungal debris in the outer ear canal
b) Perforation of the ear drum.
c) collection of fluid behind the ear drum i.e. in the middle ear (common in children, also called glue ear)
d). Discontinuity or fixity of the small bones of middle ear (ossicles)
Conductive Deafness – Treatment
Wax or fungal debris blocking the outer ear canal can be removed by suction cleaning with the help of ear microscope.
Perforated ear drums can be surgically repaired. The surgery is known as tympanoplasty where a thin fascia harvested from a muscle which is located just above the pinna, is laid under the remaining ear drum. At the same time the ossicles (small bones of the middle ear) are inspected for their continuity and repaired if needed. The fascia acts like a scaffold over which the original ear drum regenerates from its edges of the perforation.
Glue ears which are persistent and do not improve with medications can be treated by an operation called myringotomy and grommet insertion where a miniature ventilation tube is fixed to the ear drum which not only allows free drainage of the glue from the middle ear but also ventilates the middle ear at the same time. The grommet/ventilation tube gets extruded by itself in 6 months to 1 year time.

Thanks for the informative post on deafness. In some cases, hearing issues can be caused by wax buildup—ear wax specialist is a safe and effective solution that can help restore clarity. Great read!
