Normally, the eustachian tube (which extends from the back of the nose to the ear) is closed unless one pops the ears (like when flying in an airplane). As such, one does not normally see the eardrum moving to and fro with breathing.
Symptoms this poor patient with patulous eustachian tube may exhibit include hearing one's own breathing inside the ear as well as autophonia (hearing yourself talk in the ear). Symptoms improve transiently when the head is placed in a dependent position (head between the knees).
Treatment is very difficult. Some medical treatments that can be tried that often is ineffective include placement of ear tubes, SSKI (super-saturated potassium iodide), premarin drops, and reserpine. Perhaps the best treatment I've seen for Patulous Eustachian Tube is that provided by Dr. Dennis Poe at Massachusetts Eye and Ear Infirmary in Boston, MA. He performs a minimally invasive endoscopic insertion of a tiny catheter into the eustachian tube. The catheter is just the right size that one can still pop ears easily to prevent eustachian tube dysfunction, but large enough so that one does not suffer the symptoms of patulous eustachian tube.
The most common problem seen in the clinic regarding the eustachian tube is actually the complete OPPOSITE problem of patulous eustachian tube. It is eustachian tube dysfunction or the "clogged" ears whereby the ear feels full of pressure and one just is not able to pop the ears to release the pressure. In this situation, the eustachian tube stays closed, even when trying to pop the ears.
