The eustachian tube joins the middle ear to the pharynx at the back of the throat.
The eustacian tube connects the inner ear to the back of the throat.
The function of the Eustachian tube is to help equalize pressure on either side of the eardrum. It connects the middle ear to the nasopharynx which is the area of the upper throat behind the nose.

The Eustachian tube connects the inner ear with the back of the throat. It occurs in both ears and drains fluids into the esophagus.
In humans, the eustachian tube connects the middle ear to a section of the throat known as the pharynx. These tubes are normally closed, but they can open to allow middle ear pressure to reach equilibrium with atmospheric pressure (think of the pops you hear when you drive up a mountain or go up in a plane). They also serve to drain mucus from the middle ear.

Otitis media (middle ear infection) is usually associated with upper respiratory infections -- pharyngitis, laryngitis (sore throat). The ear has a tube, the eustachian tube, that connects the middle ear with the oropharynx (very back of throat, behind uvula) to maintain pressure equilibrium with atmospheric conditions. Sometimes the infection in the middle ear can drain through that tube and irritate the throat...OR the infection starts lower in the throat or lungs and can ascend through this tube and cause an ear infection.
it is an ENT or ear, nose, and throat doctor
The part of the ear that connects it to the outside world is the outer ear. The outer ear contains the ear drum and the bell. The bell is the part of the ear that shows on the outside.
This is the tube that connects the ear with the throat. Its function is to equalize air pressure on both sides of the eardrum to keep the eardrum from rupturing and to reduce pain that may be felt when air pressure is reduced. When a person yawns or swallows, the eustachian tube opens, and some of the air in the middle ear may pass into the throat, adjusting the pressure in the middle ear to match the pressure in the outer ear.
I would imagine the whole ear, and if an infection spreads from the throat to the ear, then you should really get that checked.
