Question 1

Where does wax come from?

Accepted Answer

Wax is made by glands just inside the ear canal. The amount of wax produced is understood to be genetic. Other factors, such as certain medications or smoking, can also affect the amount of wax produced.

Question 2

What are the Eustachian Tubes?

Accepted Answer

The Eustachian Tubes are two very narrow tubes that connect the middle ear to the throat. They have two main purposes; one is to drain fluid from the middle ear down to a small opening at the back of throat, the other is to allow pressure between the outer ear and the inner ear to equalize. 
The Eustachian normally lies closed and opens when you swallow, yawn or sneeze.
They also open when you perform the Valsalva maneuver. This is when you hold your
breathe and gently apply pressure through the nose until the ears “pop” causing the
Eustachian tubes to open. Air pressure is then equalized between both outer and inner ear.
